    In the manufacture of brushes, especially
    Toothbrushes
    Bristle filaments are held in a so-called material box and removed by means of a compartment device. For that, the
    Rule at least
    Recording room stocked bundles from this
    Compartment device in the one compartment notch, in which the in the
    material box
    Bristle filaments still loose using a
    Material presser are promoted.

    Relative movement between the compartment device and the
    Recording room of the material box is in the
    Material box of stocked bristle material is removed in portions, in order to be finally attached to a brush body or a bristle holder in the further process.
    The material presser is used to fill the one or more compartment notches of the compartment device.
    To do this, the
    Bristle filaments of that

    Recording room of the
    Material box, which also as
    Material box channel can be referred to
    Towards one
    Removal opening of the
    Material box against the
    Compartment device pushed and finally get into the at least one in the
    Compartment notch located compartment when this is moved to the receiving space of the material box.
    The should in the
    Usually upright or even vertical and closely lined up
    Bristle filaments through the
    Material presser on the one hand protected from falling over and on the other hand at
    BE2018 / 5077 continuous consumption of the stock of loose bristle filaments can be transported further in the direction of the compartment device. The fill level of the
    Material box gradually. Before the material box is completely emptied, bristle filaments are refilled.
    This can be done manually or automatically.
    For a satisfactory
    Removal of
    Bristle bundles from the stock of loose bristle filaments
    Help the
    The compartment device has
    Material pusher a special meaning, since this the
    Bristle filaments ultimately the
    Compartment device feeds. So far from the
    State of
    Known technology
    Procedure and
    Removal devices can
    Removal of
    Bristle bundles from the in the
    Recording room of the
    Material box located
    Stock of loose
    Bristle filaments are subject to certain fluctuations that can affect the quality of the brushes produced.
    The object of the invention is therefore to provide a method, a removal device and a brush production machine of the type mentioned at the outset, with which the removal of bristle bundles from a supply of loose bristle filaments and thereby the quality of the brushes to be produced can be improved.
    To solve this problem, a method of
    BE2018 / 5077 proposed initially proposed type with the means and features of the independent claim directed to a method for removing bundles of bristles. In particular, it is proposed in the method of the type mentioned at the outset to control and / or regulate a pressure force with which the material presser acts on the bristle filaments in the receiving space in such a way that the bristle filaments of the compartment device also have a defined material pressure when the degree of filling of the at least one receiving space changes be fed.
    In this way, the pressure force of the
    Material pusher depending on the degree of filling of the receiving space are controlled and / or regulated so that the material pressure in the receiving space, in particular in the area of removal or transfer of the bristle filaments from the receiving space to the compartment device, regardless of the degree of filling of the receiving space to a defined value or material pressure setpoint and preferably can be kept constant.
    The basis for this improvement according to the invention was the finding that the total mass of the individual bristle filaments within the receiving space has a certain stiffness or resilience. Lined up closely, the individual bristle filaments act like a multitude of springs, some of which are arranged in parallel, some in a row. With the continuous removal of bristle filaments, the
    According to the decreasing degree of filling of the material box or the at least one receiving space, the overall stiffness of the mass of bristle bundles in the receiving space, in combination with other factors influencing the supply of the bristle filaments to the compartment device, lead to a significant reduction in pressure when the bristle bundles are supplied to the compartment device , Because of these influences, it has hitherto been difficult or not possible at all to keep the material pressure required for a uniform removal in the receiving space at a defined pressure value.
    For example, if the bristle filaments consist of a comparatively soft material and / or have a round cross-section, it is possible that the pressure force introduced is not completely passed on in the direction of the compartment device and used for the transfer of the bristle filaments to the compartment device. In the case of such bristle filaments, which due to their geometry also have different stiffnesses depending on the direction of loading, for example because they have a cross-section that deviates from a circular shape, in particular oval, square, polygonal, star-shaped or x-shaped cross section, the previously described effect of reducing the pressure when feeding the bristle bundles can occur be even more pronounced on the compartment device. Furthermore, the difference between the pressure drop that occurs with a full material box can be compared to the pressure drop that occurs
    BE2018 / 5077 an at least partially emptied material box with such bristle filaments that have a cross-section deviating from a circular shape, is even more pronounced than with bristle filaments with a circular cross-section. Therefore, when processing bristle filaments that have a cross-section that deviates from a circular shape, the invention can have a particularly positive effect on the uniform supply and division of bristle bundles.
    With all bristle filaments it can happen that the pressure in the bulk of the loose bristle filaments within the receiving space is also distributed over the side bars of the material box that laterally delimit the receiving space. As soon as the individual bristle filaments are moved past the lateral boundaries or side strips of the material box, a frictional force can also arise, which can also increase the pressure reduction. The more bristle filaments that lie against the lateral boundaries of the material box, the higher the total friction loss. This can increase the pressure reduction between a removal point of the bristle filaments from the receiving space and the material presser.
    If the material pressure that is present within the receiving space on the stock of loose bristle filaments is to be kept at a defined value, it is therefore expedient to operate the material presser with a full material box with greater pressure than with a material box with a lower fill level. The readjustment required for this or
    BE2018 / 5077
    Readjustment of the material pusher is now made possible by the method, with the effect that the material pressure when removing bristle filaments and changing degree of filling of the receiving space can be kept at a defined pressure value as far as possible.
    In order to be able to remove a constant number of bristle filaments from the supply of loose bristle filaments with the aid of the compartment device, in particular with the aid of compartment notches of the compartment device, it can be expedient if it is in contact with a removal opening of the receiving space that faces the compartment device To keep the material pressure constant, even if the fill level is reduced during the continuous removal of bristle filaments from the supply of loose bristle filaments in the receiving space of the material box.
    In this context, it can be particularly useful if the pressure force of the material presser is controlled and / or regulated in such a way that an essentially constant material pressure is present at a compartment notch of the compartment device or at least in an adjacent removal area of the receiving space - regardless of the degree of filling of the material box ,
    Around the bristle filaments of the compartment device with a defined, preferably constant,
    Supplying material pressure, it can be advantageous
    BE2018 / 5077 if the pressure force of the material presser is controlled and / or regulated depending on a position of the material presser in the receiving space. The position of the material pusher in the receiving space can be used to draw indirect conclusions about the fill level of the material box. If the material pusher is still at a comparatively large distance from the removal opening of the receiving space, it may be necessary to increase the pressure force of the material pusher in order to be able to apply the defined — preferably constant, material pressure, particularly in the removal area of the receiving space, that is to say in the area of the removal opening of the receiving space ,
    Furthermore, it is also possible to control and / or regulate the pressure force of the material presser as a function of an actual material pressure in the receiving space.
    The actual material pressure value can be determined, for example, by means of at least one pressure sensor. This pressure sensor can be arranged, for example, on an inner wall of the material box facing the at least one receiving space. Particularly preferably, the at least one pressure sensor can be arranged adjacent to a removal opening of the material box facing the compartment device. In this way, the material pressure in the receiving space can be determined as close as possible to an actual removal point at which the individual bristle filaments of the compartment device, in particular one in the
    BE2018 / 5077
    Compartment device introduced compartment notch, are supplied.
    In principle, it is conceivable to determine the material pressure directly on or in the compartment notch of the compartment device. However, since this can disrupt the removal process and good results can already be achieved if the material pressure is determined adjacent to the aforementioned removal opening of the material box from which the bristle filaments are fed to the compartment device, this is not absolutely necessary.
    Depending on the design of the
    Material box, it is possible to measure the actual material pressure using at least one sensor
    accommodation space
    Inner wall of a
    Laterally delimiting the recording space
    Sidebar and possibly also on one of the
    Recording room facing
    Inner wall of a
    To determine the counterpart of the material box.
    Such one
    Counterpart can be between the one
    Side sidebar of the
    Material box and the
    Compartment device to be positioned. This way you can in several places
    Material pressure actual values can be determined within the recording space. Thus, the
    Control and / or
    Regulation of
    Pressure force of the
    Material presser may be done even more precisely.
    To regulate the pressure force of the material presser, it can be advantageous if a determined material pressure actual value in the receiving space is combined with a
    BE2018 / 5077
    Material pressure setpoint is compared and the pressure force of the material presser is adjusted depending on a determined deviation between these values in order to reduce or equalize the deviation.
    If the determined material pressure actual value is too low, the pressure force of the material presser can be increased until the
    Actual material pressure value
    Material pressure setpoint corresponds. Is the
    Material pressure actual value too high, the pressure force of the
    Material presser can be reduced to the loose bristle filaments within the receiving space in order to bring the actual material pressure value to the desired material pressure value. The material pressure in the region of the removal opening of the material box can preferably be kept constant even when the fill level of the material box changes, so that the same number of individual bristle filaments can be combined into bristle bundles with the aid of the compartment device.
    The material pressure setpoint with which the determined
    Material pressure actual value is compared, for example, in a data memory
    Removal device can be stored and read from this to the previously described
    To be able to make a comparison.
    It is also conceivable to determine the position of the material presser in the receiving space and then the pressure force of the material presser to one of the determined positions of the material presser,
    BE2018 / 5077 to adjust the position-dependent pressure force setpoint accordingly. The fill level of the receiving space can be inferred from the position of the material presser within the receiving space. If the material pusher is still at a comparatively large distance from the removal opening of the material box, it may be necessary to apply a higher compressive force to the bristle filaments in the interior of the receiving space through the material pusher in order to achieve the defined material pressure, particularly in the area of the removal opening of the receiving space. If the distance between the material presser and the removal opening of the receiving space is reduced because the degree of filling or fill level of the material box is reduced, the pressure force of the material presser on the bristle filaments can be successively reduced in order to keep the material pressure in the receiving space constant.
    The position of the material presser in the receiving space can be determined using a displacement sensor. However, it is also possible that the material presser, in particular on a pneumatically operated push rod of the material presser, has a position measuring system with which the position of the material presser in the receiving space can be determined.
    The position-dependent pressure force setpoints can be or are stored in a data memory, for example in the form of a pressure force curve which depicts the relationship between the required pressure force and the position of the material presser in the receiving space. From this data storage the
    BE2018 / 5077
    Compressive force setpoints can then be read out if required.
    In addition, it is conceivable to control or regulate the pressure force of the material presser as a function of further parameters, in particular external parameters. For example, a number of bristle filaments could be determined in a brush hole of a brush with a bristle bundle at a position outside the removal device. If the number of individual bristle filaments of the bristle bundle attached there is too small in the brush hole, this can mean that the material pressure in the receiving space of the material box must be increased. On the basis of this knowledge, the pressure force of the material presser can then be increased accordingly. The number of bristle filaments combined in a bristle bundle can be determined automatically, for example, using a camera or manually, for example, under a microscope.
    From time to time it may be necessary to check the position-dependent pressure force setpoints assigned to the individual positions of the material presser in the receiving space. For this purpose, it can be provided that the material pressure in the interior of the receiving space is determined from time to time by means of a pressure sensor with material pushers located in a specific position in the receiving space. If the detected material pressure actual value deviates from the specified material pressure setpoint, this can mean that the position-dependent pressure force setpoint of the material presser that the
    BE2018 / 5077 is assigned to a specific position of the material presser in the receiving space, is no longer correct. The pressure force setpoint can then be adjusted. In this case, it can be expedient to store the corrected position-dependent pressure force setpoint of the material presser, for example, in a data memory.
    It can be advantageous if a pressure sensor is brought into a measuring position in the area of one or the removal opening of the receiving space of the material box, if the compartment device, in particular with a compartment notch, is not in the removal position at the removal opening in order to minimize the actual material pressure value Determine the distance to the tapping point, in particular to the compartment notch.
    The object is also achieved by a removal device of the type mentioned at the outset with the means and features of the independent claim directed to the removal device. In particular, in order to achieve the object in such a removal device, it is proposed that the removal device have a control and / or regulating unit that is set up to control and / or regulate a pressure force with which the material presser acts on the bristle filaments in the receiving space that the bristle filaments of the compartment device are supplied with a defined, preferably constant, material pressure even when the degree of filling of the receiving space changes. In this way, a removal device is created that
    BE2018 / 5077 is suitable for carrying out the method described above.
    In this context, it can be expedient if the control and / or regulating unit is set up to control and / or regulate the pressure force of the material presser as a function of a position of the material presser in the receiving space. As already stated above, the compressive force of the material presser on the bristle filaments located in the receiving space can be increased if the material presser is arranged in a position in the receiving space that is a comparatively large distance from a removal opening of the receiving space through which the bristle filaments of the compartment device are fed. having.
    As the distance between the material presser and the removal opening and / or the compartment device of the removal device decreases, the compressive force of the material presser can also be gradually reduced. As fewer bristle filaments are arranged between the material presser and the compartment device as the distance between the material presser and the compartment device is reduced, the spring effect described above is reduced, so that the pressure force losses and the pressure force distribution within the supply of loose bristle filaments are less pronounced and the pressure force of the
    Material presser can be reduced to keep the material pressure at the predetermined value.
    BE2018 / 5077
    Particularly preferably, the control and / or regulating unit can be set up to control and / or regulate the pressure force of the material presser in dependence on an actual material pressure value in the receiving space.
    In order to determine the actual material pressure value in the receiving space, it may be expedient if the removal device has at least one pressure sensor which is connected to the control and / or regulating unit via a data connection and with which the material pressure in the receiving space can be determined.
    This at least one pressure sensor can, for example, be arranged or arranged on an inner wall of the material box facing the at least one receiving space of the material box.
    In principle, it is also conceivable that the removal device comprises a pressure sensor which, if required, can also determine the material pressure on the compartment device, in particular in or on a compartment notch of the compartment device. For this purpose, this pressure sensor can be positioned in or on the compartment notch.
    To determine an actual material pressure value in the receiving space, at least one pressure sensor can be arranged on an inner wall of a side bar that laterally delimits the receiving space. One, possibly another, pressure sensor can also be on
    BE2018 / 5077 of an inner wall facing the receiving space of a counterpart of the material box. This counterpart can be positioned between a side bar of the material box that laterally delimits the receiving space and the compartment device.
    In order to be able to control and / or regulate the pressure force of the material presser as precisely as possible, the control and / or regulating unit can be set up to process an actual material pressure value determined by a pressure sensor, for example the one mentioned above, with one in one
    Data storage of the removal device deposited
    Compare material pressure setpoint.
    Depending on a determined deviation between the measured
    Material pressure actual value and the deposited
    Material pressure setpoint can be the pressure force of the
    Material pusher can then be adapted, for example by a corresponding control signal to an actuator of the
    Material presser transferred and the

    This with the
    Goal that
    To be able to feed bristle filaments to the compartment device with a defined, preferably constant, material pressure. A pneumatic pressure cylinder, for example, can be used as an actuator
    Push rod is connected to the material presser.
    In order to determine a position of the material pusher in the receiving space, the removal device can have a displacement sensor connected to the control and / or regulating unit via a data connection. It is also conceivable that the material pusher for determination
    BE2018 / 5077 its position in the receiving space, in particular coupled to a push rod of the material presser,
    Path measuring system that has a
    Data connection is connected to the control and / or regulating unit.
    The data determined by the displacement measuring system or the displacement sensor can then be transmitted via the
    Transfer data connection to the control and / or regulating unit, processed by it and to
    Change of
    Material pressure depending on the position of the
    Material pusher in the recording room can be converted into a control signal.
    As already mentioned above, the removal device can have a data memory. Position-dependent pressure force setpoints for the material presser can be stored in this data memory at defined positions of the material presser in the receiving space. In addition, it is possible for the or a further data memory of the removal device to contain correction data, depending on which the pressure force of the material presser can be changed via the control and / or regulating unit.
    It should be mentioned that the control and / or regulating unit of the removal device has a signal converter for converting the measurement signal transmitted by the at least one pressure sensor, a signal converter for the at least one actuator of the material presser and a calculation module and / or a comparator or comparator and at least one data memory may include.
    BE2018 / 5077
    In particular in the case of pneumatically driven material pressers, a pneumatic cylinder as an actuator, which is then connected to the material presser via a push rod, can be driven via an electrically controllable pressure regulator. If electrically driven material pressers are preferred, an electric motor could be controlled via a variably controllable current source. For example, linear motors are known which already have integrated displacement measuring systems with which the position of the material presser (s) in the interior of the respective receiving space could then also be determined, if necessary, without separate displacement sensors.
    The task is also accomplished by a brush manufacturing machine of the type mentioned at the beginning

    Two exemplary embodiments of the invention are described in more detail below with reference to the drawing. They show in a partially highly schematic representation:
    Fig. 1 shows a first embodiment of a removal device of a brush manufacturing machine according to the invention, wherein a material box of the removal device with a single, opening into a removal opening with bristle filaments located therein and a material pusher longitudinally displaceable within the receiving space can be seen, and
    Fig. 2 is an illustration of an inventive
    Embodiment of a
    Brush manufacturing machine with a removal device, a swiveling three-color material box and one
    Darning tool, being between
    Material box a compartment device for
    Removal of
    Bristle bundles from the three recording rooms of the
    Material box is arranged.
    In the following description of various embodiments of the invention, elements that correspond in their function contain identical reference numerals even with a different design and shape.
    BE2018 / 5077
    FIGS. 1 and 2 show different embodiments of a removal device, generally designated 1, for a brush manufacturing machine 2, as is shown, for example, in FIG. Each of the removal devices 1 shown in the figures is designed to remove individual bristle bundles 3 from a supply of loose bristle filaments 4.
    Each removal device 1 has a material box with at least one receiving space for receiving the
    Loose stock
    Bristle filaments and one
    Compartment device on.
    While the
    Removal device according to
    Figure one
    Material box 5 with only one
    Recording room for
    Has bristle filaments
    Removal device 1 according to FIG. 2 via a
    Material box 5, the one with three separate
    Recording rooms 6 is equipped.
    In the embodiment shown in Figure 2
    Removal device can in the receiving rooms 6
    Bristle filaments 4 are kept, which differ in terms of their color and / or their
    Materials and / or hers
    Differentiate cross-section from each other.
    Such one
    Material box is also called
    Labeled three-color material box.
    The compartment device 7 of the removal device 1 according to FIG. 1 is a so-called compartment disk, on the outer circumference of which a plurality of compartment notches are introduced radially into the compartment disk
    BE2018 / 5077 can be recognized. The compartment notches 8 serve to separate individual bristle bundles 3 from the supply of loose bristle filaments 4.
    The compartment device 7 of the removal device 1 according to FIG. 2 is a so-called circular-arc compartment which also has a compartment notch 8 on a front side facing the material box 5 for removing a bundle of bristles 3 from the stock of loose bristle filaments 4.
    With the help of both compartment devices 7, at least one bristle bundle 3 can thus be removed from the supply of loose bristle filaments 4 per working stroke and transferred to a downstream processing station, for example a tamping tool 9 shown in FIG. In each of the receiving spaces 6 shown in the figures, a material presser 10 is provided, which can be moved within the receiving space 6 in order to press the loose bristle filaments 4 in the direction of the compartment device 7.
    Each of the removal devices 1 has a control and / or regulating unit 11, which is set up to withstand a pressure force with which the
    Material pusher 10 can control and / or regulate the respective receiving space 6, 4 of the compartment device 7, preferably constant, even if
    Bristle filaments 4 acted upon in such a way that the bristle filaments are supplied with a defined material pressure, the degree of filling of the
    Material box 5 with continuous removal of
    BE2018 / 5077
    Bristle filaments 4 changes.
    The control and / or regulating units 11 are also set up to control and / or regulate the pressure force of the respective material presser 10 as a function of a position of the material presser 10 in the associated receiving spaces 6. Furthermore, the control and / or regulating units 11 are set up to control and / or regulate the pressure force of the respective material presser 10 as a function of an actual material pressure in the receiving space 6.
    To determine the actual material pressure values, the removal devices 1 shown have at least one pressure sensor 12 for each receiving space 6. Each of the pressure sensors 12 is connected via a data connection 12a to the control and / or regulating unit 11 assigned to it. For the sake of clarity, these data connections 12a are not shown in FIG. 2.
    According to FIG. 1, the removal device 1 has at least one pressure sensor 12 for each receiving space 6. According to FIG. 1, a pressure sensor 12 is arranged on an inner wall 13 of the material box 5 facing the receiving space 6 adjacent to a removal opening 14 of the material box 5 facing the compartment device 7. In the removal device 1 according to FIG. 1, a pressure sensor 12 is arranged on an inner wall 13 of a side bar 15 which laterally delimits the receiving space 6. A second pressure sensor 12 is located on the receiving space 6
    BE2018 / 5077 facing inner wall 13 of a counterpart 16 of the material box 5 is provided. This counterpart 16 is positioned between the side bar 15 which laterally delimits the receiving space 6 and the compartment device 7. In this way, the removal device 1 according to FIG. 1 is set up to determine the actual material pressure value near the compartment device 7 and the removal opening 14.
    In the material box 5 of the removal device 1 according to FIG. 2, at least one pressure sensor 12 is assigned to one of the three receiving spaces 6, which are separated from one another by side strips 15. In addition, a pressure sensor 12 is provided on each of two counterparts 16 of this removal device 1, these counterparts 16, similar to the removal device 1 according to FIG. 1, being arranged between the material box 5 and the compartment device 7 of this removal device 1.
    The control and / or regulating units 11 are set up to compare an actual material pressure value determined by the at least one pressure sensor 12 with a target material pressure value stored in a data memory 17 of the removal devices 1 and to determine a deviation between the target material pressure value and the actual material pressure value. Depending on the deviation between these values determined in this way, the pressure force of the material presser 10 is then adapted via a corresponding actuating signal to an actuator 18, which is, for example, a pneumatic one
    BE2018 / 5077
    Printing cylinder can be.
    Each of the removal devices 1 shown also has a displacement sensor 19 for each material presser 10, which is connected via a data connection 19a to the control and / or regulating unit 11 assigned to it and with which the positions of the individual material pressers 10 in the receiving spaces 6 are determined can. The displacement sensors 19 can be viewed as part of a displacement measurement system.
    As both figures show, the actual material pressers 10 are each connected to the actuator 18 assigned to them via a push rod 20. Position-dependent compressive force setpoints, for example in the form of compressive force curves, which represent the relationship between the position of the material presser 10 in the receiving space 6 and the required compressive force, are stored in the data memories 17 of the removal devices 1 for individually defined positions of the material pressers 10 in their receiving spaces 6.
    In addition, so-called external correction data can be stored in the data memories 17, depending on which the pressure force of the material presser 10 can be changed via the respective control and / or regulating unit 11. As already explained above, such correction data can be, for example, a determined number of bristle filaments 4 combined in a bristle bundle 3. If this number is too low, the

    Compressive force of the material presser 10 can be increased, for example, in order to also increase the number of individual bristle filaments 4 in bristle bundles 3 which are divided after the adaptation of the compressive force of the material presser 10 with the aid of the compartment device 7.

    Perform procedure:
    To remove bristle bundles 3 from a stock of loose bristle filaments 4 located in a receiving space 6 of a material box 5, the
    Bristle bundle 3 is removed from the supply of loose bristle filaments 4 by means of the compartment device 7 and transferred to a downstream processing station, in the case of the brush production machine 2 according to FIG. 2, to the stuffing tool 9. The bristle filaments 4 are pushed through the receiving space 5 by means of a material presser 10 and fed to the compartment device 7. It is provided that a pressure force with which the material presser 10 acts on the bristle filaments 4 in the receiving space 6 is controlled or regulated in such a way that the bristle filaments 4 of the compartment device 7 are supplied with a defined, preferably constant, material pressure, even if the degree of filling changes of the recording room 6 changes. The pressure force of the
    Material pusher 10 can be controlled and / or regulated depending on a position of the material pusher 10 in the respective receiving space 6.
    BE2018 / 5077
    It is also possible to control and / or regulate the pressure force of the material presser 10 as a function of an actual material pressure value in the receiving space 6. The pressure sensors 12 are provided to determine the actual material pressure values in the individual receiving spaces 6. Pressure sensors 12 are arranged on an inner wall 13 of the material box 5 facing the receiving space 6 and here in a concrete manner adjacent to the removal opening 14 of the material box 5 facing the compartment device 7.
    The actual material pressure values determined in this way are then compared with a material pressure setpoints stored in the data memories 17 of the removal devices 1. Depending on a determined deviation between these values, the pressure force of the material presser 10 is adapted in order to keep the material pressure in the receiving space 6 constant at a defined value.
    The positions of the material presser 10 in the
    Recording rooms 6 are also determined with displacement sensors 19. After determining the positions of the
    Material pusher 10, the respective compressive force of the individual material pusher 10 one of the so determined
    Positions of the respective material presser 10 assigned position-dependent pressure force setpoint are adjusted accordingly.
    Especially when teaching the so defined
    Control and / or regulation may occur from time to time
    BE2018 / 5077 become necessary to check the position-dependent pressure force setpoints stored in the data memory 17. Here, an actual material pressure in the receiving space 6 can first be determined by means of a pressure sensor 12. If this actual material pressure value is too low in comparison to the required material pressure setpoint, the pressure force setpoint stored in the data memory 17 for the corresponding position of the material presser 10 can be adjusted in order to finally use this control or regulating circuit to determine the position-dependent pressure force setpoints for the
    Material presser 10 gradually update. This adjustment or update of the
    Compressed force setpoints stored in data memory 17 may be required, for example, when the brush manufacturing machine 2 starts up again, the temperature or air humidity changes or bristle filaments 4 made of a different material are inserted.
    In addition, if necessary, a pressure sensor 12 can be brought into a measuring position between at the removal opening 14 of the material box 5 if the respective compartment device 7 with its at least one compartment notch 8 is not in engagement with the removal opening 14 of the material box 5. This is done with the aim of at least at certain time intervals to determine an actual material pressure value as close as possible to the tapping point and the compartment notch 8.
