    The invention relates to a method for producing brushes, in particular toothbrushes, which have tufts of bristles with machined individual bristles, in particular polished, at their useful ends, the material for bristles being fed to the machining of the bristle ends as a sheathed sheath of skewer having a cross section of skein which corresponds to a multiple of the cross section of a tuft of bristles and a section of the bristles skein being cut after machining of the free end of the skein.
    The invention further relates to a device for producing brushes having tufts of bristles, in particular toothbrushes, comprising a feed device for skewer-shaped hair material having a sheath, having a skewer cross section which corresponds to a multiple of the cross-section of a tuft of bristles, a machining device for machining the bristle ends, a support device for supporting the skein of bristles away from its free end and for positioning it during machining of the free end of the skein of bristles as well as a cutting device for severing skein sections.
    It is already known from DE 43 14 692 A1 how to machine, in particular polish, skeins of bristles in the assembly at the free end. Then the whole of the skein is divided into individual skeins or tufts of hair. Skeins or tufts of divided hairs are transported with a perforated transport plate.
    Document DE 10 2004 054 839 A1 discloses a method and a device for making brushes, in which the bristle material is fed to the machining of the bristle ends as a skew of bristles having a cross-section. skein which corresponds to a multiple of the cross section of the tuft of bristles and the free end of the skein of bristles is then machined. The bundle of bristles is provided with a sheath that is removed before a support and positioning device and therefore before machining the skein of bristles.
    Then, a skein section corresponding to the desired length of the tuft of hair is separated. On the skein section to be separated, mountable and removable transport supports are provided in the form of collets, rubber rings and / or spring ring.
    The task of the present invention is to provide a method and a device of the type mentioned at the beginning for making brushes with which tufts of brushes can be prepared in a simplified manner and can be brought to further processing in different ways.
    To solve this problem, it is proposed with regard to the method according to the invention that the skein of hair is supported at a distance from its free end and that the sheath surrounding the skein of hair is partly removed in the area which protrudes, that the free end of the skein of bristles is machined and that before cutting a skein section in the skein of bristles, an annular sheath section is separated from the sheath that protrudes from the support zone and either push on the section of skein to be sectioned.
    As regards the device according to the invention intended to implement the method, it is proposed that the feeding device has at least one support device for a skein of sheathed hair by means of which the skein of hairs can be positioned at least in the longitudinal direction of a sheath removal device, that the sheath removal device is configured to partially remove the sheath that protrudes from the support area of the skein of bristles and that a device for separating and moving an annular sheath section which protrudes and for pushing this annular section onto the skew section to be cut is provided.
    Advantageously, the sheath of the skeins of hair, which is present in the delivery condition, thus continues to be at least partly used to hold together a severed skein section. Expensive devices usually required, with supports that are positioned around the skein section, are no longer needed.
    The skein of sheathed hair can, in this case, be supported in a first station and a section can be removed from its sheath in the predefined free length of the skein of bristles which protrudes from the support zone to a sheath. remaining following the support area. This remaining sheath is dimensioned in length so that an annular sheath section can be separated therefrom, which will be pushed later on the skew section to be severed. In this case, this skein section may be significantly shorter than the length of the skein of bristles protruding from the support zone.
    The excess length of the skein of bristles is adjusted to the intended polishing treatment of the free ends of the bristles and, in this case, in particular to a predetermined polishing result. In this case, a tip polishing of the bristle ends is obtained in the case of a longer overspill length, while a more rounded or flat polishing is performed in the case of a smaller overshoot length. The skein of bristles protruding from the support device makes a circular motion upon contact with the polishing surface.
    The annular sheath section may already, prior to the polishing treatment, be separated from the remaining sheath or may be perforated at this subsequent separation location so that substantially the entire length of the skew of the pile is thereby movably arranged for the circular movement of offset. On the other hand, the annular sheath section may also be separated only later before cutting the skein section and then pushed onto the skew section to be severed. In the latter case, the excess skein may be somewhat stabilized by the remaining sheath and stiffer with respect to the circular motion during polishing, which may be considered for a planned polishing result.
    By changing the distance between the support device and the free end of the skein of hair that is to be treated, it is possible to influence the result of the polishing.
    This is why the skein of bristles can be positioned lengthwise at least during the treatment, if necessary during the separation or displacement of the sheath or during the sectioning process of the skein section.
    During the machining of the skein of bristles, different polishing treatments of the end of the skein of bristles can be undertaken in several polishing stations, where appropriate with rotational speeds, polishing devices and / or different polishing surfaces.
    It is particularly advantageous that the annular sheath section separated from the sheath which protrudes from the support zone is folded over the skein section to be sectioned, in particular accordion.
    On the one hand, the length of the annular portion of the sheath is therefore not critical, that is to say that it can vary within certain limits, and on the other hand, one obtains, because of this folding, a radial narrowing of the annular section through which the gripped and supported skein section is held together even more safely. This is of great importance, especially in the case of very short skein sections. In addition, a better holding of the skein section can thus be achieved, even in the case of less elastic sheath material and less axial length.
    According to a configuration of the invention, the length of the annular sheath section may be smaller than the length of the skewer section to be cut and this sheath section may be moved, prior to sectioning of the skein section, by being pushed on it.
    In this case, after having cut the skein section of the skein of hair, it is advanced by the length of the separate skein section and a section corresponding to the extended length, after deduction of the length of the skein. circular sheath section, is separated from the sheath that protrudes from the support area of the skein of bristles.
    According to another embodiment of the invention, the length of the annular duct section may correspond to the length of the skewer section to be cut, this duct section being displaced, before the skew section is cut, being push on it. The separation of a piece remaining from the sheath is not necessary in this case so that the economy of an operation.
    The length of the annular duct section may also be greater than the length of the skewer section to be sectioned. In this case, the annular sheath section is moved, prior to severing the skein section, by being pushed and folded accordionally thereon until its length is equal to, or preferably less than, the length of the skein section to be sectioned.
    The device according to the invention can present as a feeding device a linear transport device along which different treatment stations are arranged in line one behind the other.
    On the other hand, the feeding device can also be configured as a carousel-shaped transport device, the different treatment stations being arranged in a circle.
    The embodiment in question depends, among other things, on the space available and the number of treatment stations.
    According to an exemplary embodiment, the sheath removal device, one or more treatment stations, the device for separating and moving the annular sheath portion and the cutting device can be arranged along the transport path of the device. support of the skein of hair.
    The sheath removal device and / or the separation and displacement device preferably have a tool for weakening the sheath at a separation location, preferably a perforating tool.
    Suitably, the perforation tool has, in this case, one or more perforation gears movable around the skein of bristles and engageable with the sheath, the perforation gears being configured so that to weaken the sheath at the separation location only to push the annular sheath portion onto the skein of bristles.
    The one or more perforation gears are engaged with the sleeve for perforating purposes and reciprocate by rolling about the skein in the circumferential direction so that a circular perforation is formed as a location for at the separation in the sheath.
    If necessary, the engagement or engagement gearwheels can then be moved in the axial direction of the skein. In this case, the annular section of sheath is separated or torn at the perforation and moved towards the free end of the skein of bristles. After positioning the sleeve ring, the perforation gears are moved radially outward and are disengaged.
    The skeins of bristles are preferably retained in a tube which can be positioned in the lengthwise direction. In the case of skeins of bristles which are slightly longer and therefore have no inherent stability preventing them from curling, which are for example a length of two meters, the tubular support guarantees a straight position defined skeins of hair.
    To position the skein of hair in the length direction, it can be provided, at least in a treatment station, a positioning device that can be coupled with the skein of hair or with the tube holding it .
    The positioning device can therefore be arranged in a stationary manner, so it does not run with the skeins of hairs transported.
    Other configurations of the invention are set forth in the other dependent claims. The invention is further explained in more detail above based on the drawings.
    It is shown very schematically on:
    Fig. 1 an installation for making brushes with a device for producing tufts of bristles, two insertion machines for filling cassettes, an injection molding machine and a packaging machine,
    Fig. 2 a skein of bristles shown in cross-section with a sheath removal device placed thereon,

    Fig. A cutting device for cutting a skein section, and
    Fig. 31 a partial view of the feeder configured as a carousel-shaped transport device.
    An installation 1 shown in FIG. 1 is used to make brushes having tufts of bristles, especially toothbrushes. This installation has a feeding device 2 for the material of the hair in the form of skeins of bristles 4 provided with a sheath 3. With the aid of the feed device 2, the skeins of bristles 4 brought into a station of equipment 5 are stripped of their sheath in a sheath removal station 6, are then polished at the free end of the skein of bristles 4 successively in three polishing stations 7, 7a, 7b and are brought, after this treatment, to a separation and displacement device 8 where an annular sheath section 10 is separated from the remaining sheath 9 (see Figs 6 and 20) and is pushed onto a section of skein 11 to be cut from the Skein 4 of hair (see Figs 13 and 26). Finally, a skein section 11 is separated from the skein of bristles 4 in a cutting station 12 and the collection of the skein sections provided with the annular sheath portion 10 finally takes place in a sampling station 13. Skew sections are placed in the embodiment according to FIG. 1, in these material cassettes 14 of two insertion machines 15. In the case where the material of the hairs in the form of skein sections is to be stored, the annular sheath portions 10 can remain on the sections of the same. skein 11 sectioned so that they are held together securely. This is of particular importance, especially in the case of very short skein sections which have, for example, a length of less than 15 millimeters. If the skein sections are placed in material cassettes 14, the sheath sections can be removed.
    With the insertion machines 15, cassettes 16 which have receiving holes corresponding to the area of bristles of a brush to be produced are filled with tufts of bristles 17 which have been removed using tuft separators 18 in the stock of bristles in the material cassettes 14. The cassettes 16 filled with tufts of bristles 17 are fed to an injection molding machine 19 where the brush bodies are injection molded and the tufts of bristles 17 are in the cassettes are at the same time injection-coated at their attachment ends. The finished brushes can then be fed to a downstream packaging machine 20.
    The feed device 2 is configured, in the exemplary embodiment, as a carousel-shaped transport device 21, a part of which is shown schematically in FIG. 31. The latter has a central axis 22 around which can rotate the supports 23 on the outer end of which a skein of bristles 4 is each time supported. The skein of bristles 4 is located inside a tube 24 and protrudes with its lower end from the tube 24. In the course of the tube 24 or at its lower end, a clamping support device 25 is provided. whereby the skein of bristles 4 can be supported by clamping in a support zone, and can also be positioned, if necessary, in the longitudinal direction. In the embodiment according to FIG. 31, there is provided, for the positioning in length, a stationary device for positioning in length 26 which can be coupled with the tube 24 and which can move the tube 24 in the assembly in the direction of the length. The tube 24 is, in this case, slidably guided in length in guide openings 27 of the support 3.
    Fig. 29 shows a polishing station 7 for polishing the ends 28 of skein of bristles and FIG. 30 shows a cutting station 12 where skein sections 11 can be separated from the skein of bristles 4. In this case, it is also possible to recognize a separation and displacement device with which, according to FIG. 29, a perforation 29a can be made in the sheath 3 by means of the perforating gears 30 at a separation point provided for separating an annular sheath section 10. This separation and displacement device 8 is movable in the direction of the length of the skein of bristles 4 and also serves to detach the annular sheath section 10 at the point of perforation. The separation and displacement device 8 further serves to push the annular sheath section 8 onto a skew section 11 to be sectioned, as can be seen in FIG. 30. The double arrow indicates that the separation and displacement device 8 is movable both in the radial direction and in the axial direction of the skein of bristles 4.
    The skein of bristles 4 is guided in a tube 24 and is supported by a clamping support device 25 disposed at the lower end of the tube 24. When the clamping support device 25 is open, the skein of bristles 4 can be pushed, so advanced after the separation of a skein section 11 or positioned lengthwise during a treatment. A sectioned skein section is received in a housing 34 in the exemplary embodiment.
    Figs. 4 to 17 shows a sequence of operations for sectioning skein sections 11 of a skein of bristles 4 provided with a sheath 3, which have ends of bristles machined at one end and are held together by a sheath portion ring 10.
    A skein of sheathed bristles 4 is first brought to the device and is supported by the clamping support device 25 indicated by arrows directed in opposite directions so that the skein of bristles 4 protrude from the clamping support device 25 with its free end. The overrun can be varied and is primarily a function of the polishing treatment that is provided each time. According to FIG. 5, the sheath 3 is partially removed from the skein of bristles 4 supported according to FIG. 4, in that a peripheral perforation 29 is made at the intended separation point. For this purpose, a perforation tool is provided with a plurality of perforation gears 30, as shown in FIG. 2. In the exemplary embodiment, there are provided four perforation gears 30 arranged in a distributed manner around the perimeter of the skein of bristles 4. A single perforation gear 30 which is arranged to run 360 ° around the skein of hair 4 is also sufficient if necessary. Since in the present embodiment, the perforation tool consisting of several perforation gears 30 is also provided for separating and moving sections of gaines to remove or position, it is appropriate to provide at least two wheels opposed perforation teeth 30, or better still three or four perforation gears, as shown in FIG. 2.
    The perforation gears 30 are in the position shown in FIG. 2, in the engagement position with the sheath 3 so that the perforation 29 is made by reciprocating movement along the perimeter of the skein of bristles 4 along the double arrow Pf 1. The perforation gear wheels 30 are movable in the radial direction of the skein of bristles 4 so that they can also be disengaged from the skein of bristles or its sheath 3. The perforation gear wheels can also be moved in the direction of the length of the skein of bristles 4 so that after the perforation, while the perforating gears 30 are still in engagement, the section of sheath to be separated or positioned can be detached from the remainder of the sheath at the level of the perforation 29 and be pushed on the skein of hair 4.
    As shown in FIGS. 5 and 6, a section within the length of the skein of bristles, which is free, predeterminable, and protrudes from the clamping support device 25, is removed from the sheath 3 of the skein of bristles 4, with the exception of a remaining sheath 9 following the clamping support device 25. This remaining sheath 9 is dimensioned so that an annular sheath section 10 for holding together the separated skein section 11 further can still to be separated.
    The sheath 3 of a newly added skein of hair 4, with the exception of the remaining sheath 9, is first removed from the part of the skein of bristles 4 protruding from the clamping support device 25 so that the Overlying skein section has sufficient lateral mobility for the following polishing treatment according to FIG. 8-10. During the polishing treatment, the distance of the clamping support device 25 from the skein ends 28 may also, if necessary, be varied to thereby influence the polishing result.
    Individual ends 31, 31a, 31b of bristles, polished differently, are shown schematically in FIG. 3. Clamping devices are indicated each time by the opposite arrows, but not in this case to scale, to show clearly that in the case of a shorter free length, ie of length skein of bristles protruding from the clamping support device 25, the individual ends 31 of bristles are, therefore, less curved or rounded polished only on their edges, while with an increasing length of overtaking, the result The rounding direction further leads to a semi-circle-shaped rounding as shown on the individual hair ends 31a and, finally, in case of greater length of protrusion at a tip-shaped polishing of the individual hair ends 31b. In addition to the length of protrusion, the length of the remaining sheath 9 also has an influence on the circular motion or the mobility of the skein section of bristles that protrudes. This can be taken into consideration when sizing the overshoot.
    In fig. 7, another perforation 29a is made in the remaining sheath 9, the length of this duct section being sized according to the length of the annular duct section 10 provided. The perforation 29a already made before the polishing treatment produces a slightly greater mobility of the skein section of bristles protruding from the clamping support device 25. If necessary, the perforation 29a can also be made in the position according to FIG. . 11, therefore before the separation of the sheath portion 10.
    In figs. 8 to 10, it is stated that the free ends 28 of the skein of bristles can be polished in different ways. As a general rule, rotary band polishers are used, the free end 28 of the skein of bristles executing a circular motion due to the linear movement of the polishing belt on the one hand and the rotation of the polisher on the other hand . The radial deviation of the circular movement is in this case, as already mentioned above, a function of the length of protrusion beyond the clamping support device 25 and can be changed by varying this length. It is provided according to FIG. 8, a polishing surface with protuberances 32 and, according to FIG. 9, with grooves 33. FIG. 10 shows a polishing station 7b where the polishing surface is provided with a smooth polishing coating. The different polishing surfaces lead to a particularly good rounding result of the individual hair ends.
    After the polishing treatment, the skein of bristles 4 according to FIG. 11 is available with ends 28 of hair whose treatment is completed. The annular unsheathed section 10 is then separated according to FIG. 12 at the perforation 29a and is pushed onto the area of the skein of bristles 4 near the end so that it is on the section of skein 11 to be sectioned. In the cutting station 12 according to FIG. 13, a skein section 11 is then separated and supported by a receiving device 34. The end 28 of the skein of bristles is, during the cutting process, at a distance from the receiving device 34 approximately in the form of a bucket so that the bristles pushed in the direction of the length during the cutting process can deviate. After cutting, the skein section 11 with the sheath ring 10 is in the receiving device 34 and can thus be evacuated. But it is also possible according to fig. That the skein section 11 supported by the sheath ring 10 is taken out differently and fed to further processing.
    According to figs. 16 and 17, the skein of bristles 4 is advanced the length of the sectioned skein section 11 and a waste section 35 is removed from the sheath 3 so that the part of the skein of bristles 4 protruding from the device clamping support 25 again has the initial state comparable to FIG. 6 with a remaining sheath 9. The treatment cycle then continues as described on the basis of FIGS. 7 to 16 until the skein of bristles 4, which may for example have a length of one to two meters, is fully used.
    Figs. 18 to 28 show a sequence of operations, Figures 18 to 25 corresponding in principle to Figs. 4 to 12. There is a difference that the length of the annular sheath section 10a approximately corresponds to the length of the skein section 11a to be sectioned. There is therefore no section of waste so that, after severing the skein section 11a and after advancing the skein of bristles 4 the length of the separate skein section, a section The skein of bristle protruding from the clamping support device 25 and suitable for further processing is directly available.
    In figs. 25 to 27, it can be seen that the annular sheath section 10a can be folded accordionally, in particular to thereby obtain a more solid circular clamping of the retained skein section 11a. In this case, the length of the sheath section 10a could be approximately equal to or longer than the length of the skein section 11a to be sectioned. It is preferably provided that the length of the accordion-folded sheath section 10a is smaller than the length of the skein section 11a so that there is a sheath-free area at which the skein section 11a can be grasped for example by a transport clamp.
