    A guiding and braking unit for a material web which passes through a processing machine, e.g. a machine for the manufacture of packing containers. The unit comprises a roller (3) adapted to a guide cylinder (1) for the web (10), this roller (3) being manufactured from a material with a high coefficient of friction. The roller (3) is adapted so that it can be swivelled via an arm (5) in transverse direction of the material web and as a result follows the material web (10) when the same is moved sideways, that is to say axially in relation to the guide cylinder (1). Each sideways movement, however, because of the suspension of the roller (3), brings about a lifting of the roller which is continuously counteracted by the pressing of the roller against the cylinder. As a result the roller is returned automatically to a central position and in so doing, owing to friction, carries the material web with it to a central position in relation to the guide cylinder (1).

    The invention relates to packaging equipment. And relates to a device for guiding and braking strip packaging material,
    The purpose of the invention is to increase the reliability of work.
    Figure 1 shows the device, side view; Fig.2 - the same general view.
    The device for guiding and braking the strip packaging material comprises a guide cylinder 1 mounted on the machine bed 2 with free rotation or from a drive and made mainly of stainless steel or rigid plastic material. A pressure roller 3, axis is mounted with a possibility of contact with it. rotation 4 which is fixed on the lever 5 having two axes 6 and 7 of rotation.
    The pivot axis 6 runs perpendicular to the axis 8 of the guide cylinder 1 and perpendicular to the feed direction of the material 9 at the entry portion of the device, and the axis 7 of rotation of the lever 5 is arranged parallel to the axis 8 of the guide cylinder 1 and is connected by a lever 10 s (silt cylinder 11 to press the roller 3 against the cylinder 1. The power cylinder 11 is also a means for retracting the roller 3 from the guide cylinder 1,
    The power cylinder 11 through the axis 12 is fixed on the frame 2 of the machine. The pressure roller 3 is installed in such a way relative to the guide cylinder 1, that their center-to-center plane 13 is displaced in the material feed direction relative to the plane 14, which is perpendicular to this direction in the entry section of the device, by an angle V in the range of 2-60, preferably 5-15 ° . The diameter of the roller 3, as well as its length, is much smaller than the corresponding dimensions of the directional tipper 1.
    The roller 3 is preferably zipindric and is made of a material with a high coefficient of friction, for example rubber or plastic. In addition, in the event of a high requirement for the braking effect of the assembly, the roller 3 may be made of a flexible material, since the braking effect is achieved mainly by

    due to the force used when deforming the roller 3 when it is pressed against the surface of the cylinder 1 by the force cylinder 11 to create a compressive force.
    During the work of the processing machine and the supply of material 9 along the guide cylinder 1, the roller 3 moves to its active position, resting on the cylinder 1, the material 9 passes between the cylinder 1 and the roller 3. Material that is either advanced by some device (not shown ), or moving forward with the help of the guide cylinder 1 and the driving engine connected to it, in turn, rotates the roller 3 around the axis 4 at a speed corresponding to the speed of the material 9, at the same time the pressure of the roller 3 on the canvas and passing over the cylinder 1 causes a deformation portion of the roller 3, which is in contact with the material. The size of the deformation depends, on the one hand, on the force with which the rod of the power cylinder 11 presses on the roller 3, pressing it against the material web, and on the other hand, on the flexibility of the material from which roller 3 is made. In the case of directional cylinders with free rotation, i.e. without the drive, the tension of the part of the web of material 9 that comes off the starting cylinder is provided by some braking effect which is created by the deformation of the roller 3. Therefore, it is advisable to choose relatively soft and flexible material of the roller 3 or relatively Press the roller firmly against the web of material using a compressive force.
    The material from which roller 3 is made also has a relatively high coefficient of friction,
    which in any case is much higher than the friction coefficient of cylinder 1; If roller 3 is made, for example, of a flexible rubber material, the friction between the roller and the
    lot of the mother; evil 9 is much greater than the friction of the material 9 and cylinder 1, which is usually made of stainless steel or other non-flexible material.

    The high friction between the roller 3 and the web of material 9 has the effect that the web of material 9, if it is for some reason moving sideways, i.e. in the axial direction of the guide ci.pindra, during feed on the guide cylinder 1 carries roller 3, so that the latter, thanks to lever 5, rotates pivotally around axis 6. In terms of its mounting geometry, each hinge roller 3 is sideways around axis 6 means that the roller lifts the surface of the cylinder 1 (or more precisely the surface of the material web located on the cylinder) and is thus raised by the action of the rod of the power cylinder 11. At the same time, the lever 5 also rotates around the second axis 7, but since the power cylinder 11 constantly forces the roller to move in the direction of the axis 8 of cylinder 1, roller 3 immediately returns to the position shown in figures 1 and 2, in which the axis is parallel with the center axis 8 of cylinder 1. Considering the high the friction between the surface of the roller and the web of material 9, the return movement of the roller 3 causes a laterally directed force that moves the web of material 9 back to its originally chosen central position relative to cylinder I. In this case, each movement of the web material Side 9 in the lateral direction relative to the cylinder 1 causes the roller 3 to rotate and lift, which immediately counteracts the power cylinder rod, which forces the roller 3 to move back to its original position and at the same time guides the web of material in such a way that it reliably moves along the surface cylinder to centered position.
    When filling the web of material, replacing roller 3 or for other reasons, roller 3 is transferred from its active position to passive with the help of a power cylinder 11. The supply of pressure medium in cylinder 11 can also vary depending on the required contact pressure between roller 3 and cylinder 1. At the same time, a higher contact pressure creates a higher braking and

    directional effects, and the most acceptable Bejni4HHa should be determined by practical experiments in relation to the type of material and the desired effect.
    Regarding the selected clamping roller installation limits, it is determined that lowering the lower limit (2 °) leads to insufficient JO orientation, since the influence of the cylinder, which usually returns the roller back to its middle position, is reduced, when the upper limit (60 °) is exceeded The f5 lindra rotational circle becomes so large that centering becomes impossible. The limit of 5-15 provides the optimum direction and braking of laminated sheets, usually 20 used as a packaging material.
    The invention creates a guide and brake assembly that can be used in these two functions, as well as simply as a guide or brake assembly of the moving web material. The assembly is compact, manufactured by simple means.
