    A method and apparatus for producing open-sided V-belts by cutting from a vulcanized, sleeve-shaped roll. The sleeve-shaped roll is disposed over two drivable rollers. A tensioning arrangement which includes one of the rollers has a weight. This weight acts solely on such roller tending to pull this roller away from the other roller. This tensions the roll. When the tensioning force attains a predetermined limit, it is partially counteracted by a force acting in the opposite direction. The counter-acting force is supplied by suitable means. Cutter means are provided for cutting the roll while it is tensioned and the counteracting force is increased by suitable means in dependence upon the number of belts cut from the roll.

    (54) METHOD OF MANUFACTURING INFINITE SOUTH BELTS AND DEVICE FOR ITS IMPLEMENTATION
    (57) The invention relates to the manufacture of rubber technical products, intended for the manufacture of endless V-belts. The purpose of the invention is to improve the quality of the belts by providing a predetermined tension on the cable regardless of the number of cut and selected annular peMHOj i. For this, the device for manufacturing endless V-belts is equipped with a movable cross-member 12 mounted between the base 1 and the platform 2 with the possibility of vertical movement. Power cylinders 14 are installed on the traverse, the rods 17 of which are rigidly connected to the platform 9. The platform 9 is mounted on the frame 2 by means of vertical bars

Such a constructive design of the device allows the tension of the wickel 6 to be produced during the cutting of the ring belts due to its own weight
    The invention relates to the manufacture of rubber technical products and is intended for the manufacture of rubber technical products and is intended for the manufacture of endless V-belts.
    The purpose of the invention is to improve the quality of the belts by providing the specified tension of a vicel, regardless of the number of cut and selected annular belts.
    Fig, 1 shows the proposed device, the longitudinal difference; FIG. 2 is a section A-A in FIG. FIG. 3 is a section BB in FIG. Fig. 4 is a control circuit.
    The device for making endless V-belts comprises a frame 2 fixed on the base 1, formed by four columns 3 and the top plate 4, and cantileverly mounted on the top plate 4 of the frame without moving the drive drum 5 (not shown) for mounting the tubular wickel 6, the device has A tool for cutting Vikel 6 into annular rollers in the form of a pair of circular knives 7. A tension device with a tension drum 8 located under the driving drum 5, cantilever ted on a vertically movable platform 9 via the rack 10 and the drive 11 for vertical movement. The rack 10 is rotatable. Between, the base 1 and the platform 9 with the possibility of vertical movement set the movable yoke 12. Tensioning tracks. As they are cut and taken from the drums 5 and 8, the knives 7 of the V-belts are cut, they compensate for the reduction in the initially set dead weight of the tensioner by increasing the pressure of the working medium in the cylinders 14.2s. and 2 hp ff, 4 silt,.
    Versa 12 is connected with spindles 13 with a drive 11. Power cylinders 14 are mounted on traverse 2.
    The platform 9 is mounted on the frame 2 by means of vertical guides 15 and bearings 16 and is rigidly connected to the rods 17 of the power cylinders 14. The device is equipped with a system for controlling the pressure of the working medium in the power cylinders 14 in accordance with the weight of the dead pin 6. This system includes means 18 for adjusting supply of the working medium to the cylinders 14,
    a computer 19 and a contact sensor 20 of the pressure of the working medium in the cylinders 14. The device is equipped with limit switches 21 for turning off the vertical transfer actuator 11 mounted on platform 9 and mounted on cylinders 14 by cams 22 for interacting with limit switches 21.
    When the device is implemented
    The proposed method of making endless V-belts is as follows.

    Include the actuator 11, which causes the rotation of the screws 13. The screws J3 raise the yoke 12 together with the power cylinders 14. Due to this, the platform 9 with the bearings 16 fixed on it, turning stand-. 10 and the tension drum 8 rises to a position in which the pre-assembled and vulcanized tubular wiquel 6 is easily mounted on the drums 5 and 8. Then, determined in a broad way by the preset for the wiquette 6 cut, vi31
    face tension Tension control is performed using the means 18, which regulates the working medium pressure in the power cylinders 14 through the computing means 19 and the contact sensor 20 of the working medium. In the cylinders 14, a predetermined pressure of the working medium is set in accordance with the predetermined tension force vikel 6.

    Then, with the help of spindle screws 13, lower the yoke 12 with the power cylinders 14 until the drums 6 with tension tighten the drums 5 and 8. In this; The preset tension of the vikel 6 is produced at the expense of the own weight of the tension device, including the tension drum 8, the post 10, the platform 9, the bearings 16 and the rods 17. The spindles 13 and the actuator 11 are turned off when the cams 22 interact with limit switches 21 at the time of reaching the cylinders 14, the set of a vickel is produced by the working force itself, which compensates for the tension of the tension of the tension on the inside of the tension. A drive drum 5 is then rotated,
    which rotates a vicel 6 at a speed zo originally given its own
    in the range from 700 to 1000 rpm. With the help of circular knives 7, the vikel is cut into separate ring V-belts with repeated retraction and supply of the knives to the vickel. After the cuts and removal from the drums 5 and 8 of the cutting ring belt, the remaining part of the vicel remains on the drums. To ensure a given tension, a vickel, regardless of the number of cut and selected ring belts, during the cutting process compensates for a decrease in the initially specified net weight of the tension device by increasing the pressure of the working medium in the cylinders 14. Increasing the pressure of the working medium in the cylinders 14 performs with the help of computing means 19. However, an increase in the pressure of the working medium in the power cylinders 14 should not lead to an improvement in the tension of vikel 6 compared to a given tension force, so as in this case, it will not be possible to ensure the exact position of the wickle on drums 5 and 8. The latter is the main prerequisite for performing accurate cutting of wickel into ring belts.
