The mechanism for moving the grippers upwards has a carriage 9 mounted on the frame of the frame, a pneumatic engine 10 with a piston 11, Each lever is fixed on the sleeve 12, and the lower part of the latter is fixed by means of a threaded connection on the rack 14 whose lower part forms the upper part of the air thrust body 15. Each the pneumatic motor 15 has a piston 16 mounted on the shaft 17, which is movably mounted for vertical rotation inside the corresponding rack 14 and the sleeve 12. The opening-closing mechanism of the open grippers has a cam 18 The upwardly facing lug 19 is formed at each end of the shaft 17. On each strut 15, a plate 20 is installed, the upper end of each plate forming a lug 2 which is below the corresponding lug 19. The spring-loaded lever 22 is pivotally fixed by means of an axis 23 on fork 24. On rye 22 there is a prong 25, which rests against plate 20 under the action of a spring. Rod 26 is snubbed on lever 22 so that it can lie in groove 27. Roller 28 is fixed on plate 20, moved along the cam, which is pushes the cam 29 in the lower part of the lever 22 with a pneumatic motor 30 mounted on the machine bed and has a movable piston 31. The piston 31 is fixed on the sleeve 32, which is fixed with its upper end on the annular protrusion 33. On the annular protrusion 33 the support for the shoe is fixed, therefore, when the piston 31 moves upwards, the support for the shoe also moves in a vertical plane. The operation of the machine is carried out as follows. First, the grippers 3, 4, 5 and 6 are located in the upper position, with the ball clamps being more elevated and located above the upper surface of the holding plate 2, the pistons 11 are in the upper position in the pneumatic drive 10. All pliers are opened , the pistons 16 are installed in the lower position in the pneumatic engine x 15. In this case, the 22 turns are turned inwards, their teeth abut 50 in the plates 20 below the projections 21. The cams 29 are installed below and away from the rollers 28 following the movement of the cams, the pistons 31 in pneumatic position 30. In this case, the support 1 for the pad is in the lower position, and the upper part of the support is lower than the level of the upper plane of the tightening plates 2. The nasal part of the workpiece is inserted between the gripping jaws, they catch the tightening edge, and the grippers 6 are lowered. They capture the tightening edge during operation of the pneumatic motors 15, in which the pistons 16 are raised and then lowered under the action of compressed air. The pneumatic motors 10 are driven and the pistons 11 are lowered. During the downward movement of the grippers 6, the pneumatic motors 15 and the plates 20 move downwards, and the plates move downward from the teeth 25 until the protrusion 21 is lower than the teeth 25, while the levers 22 rotate around the axes 23 to move the teeth 25 into the projections 21. During the lowering of the ball grips, the 6 rounded portions of the toe of the workpiece are stretched around the pads. Due to the force applied to the grippers by the pneumatic extensions 10, such a downward movement ends when the resistance to stretching of the workpiece is greater than the tensile force applied by the pneumatic motors 10 during the downward movement. Air motor 30 is now driven by compressed air. The piston 31 rises together with the support 1, and the tightening edge of the workpiece is gripped by all grippers 3, 4, 5 and 6, causing the shoe with the workpiece to rise, and the toe part of the workpiece to stretch around the front part of the shoe. The pad support completes its lift when the upper portion of the support 1 is above the level of the upper surface of the pull plates. Any tendency to lift the support 1, and the operator of the gripper 6 will rise under the action of compressed air, will prevent the pistons 11 from moving downwards, as the teeth 25 rest against the protrusions 21. The grips 6 of the ball grippers 6 are kept at the level of the support 1. that are below the top surface of the plate. End plates have reciprocating motion. First, the tightening plates are moved to the operating position in which they are close to the contour of the pad. Due to the action of the teeth 25, which abut against the protrusions 21 to prevent the grippers 6 from rising above the lower surface of the tightening plates 2, the pneumatic motor 30 is prevented from lifting the pads with the workpiece during engagement working position. After that, the block with the workpiece is held on a support. The glue is pressed along the contour of the toe part of the block, and the tightening plates 2 are moved inwards towards the block, grasping the tightening edge and pressing it against the contour of the pad trace to connect the tightening edge with the trace. During the stroke of the tightening plates, the grippers 3, 4, 5 and 6 release the tightening edge, allowing the tightening plates to work without interference. The grippers release the tightening edge as a result of the operation of the pneumatic motors 15 and the pistons 16 moving down. 010 When releasing the tightening edges of the ball grippers, the resistance of the downward movement of the grippers that previously fixed the tightening edge is weakened, so that the pistons 11 move to the lower wall of the air motor 10, carried grabs further down. Such a downward movement causes the struts 14 and the air motors 15 to move further down. As a result, the bikes 28, following the movement of the cams, will contact the cam 29, turning the lever 22 around the axes 23 and shifting the teeth 25 away from the projections 21. At the end of the device operation, the back plates 2 return to their original position, in which they no longer they are above the grippers, in this case the air motors 10 are actuated, raising the pistons 11 to the idle position. Blocking the levers 22 in their outer positions during such lifting and placing the teeth 25 outside the projections 21 does not prevent the pistons 11 and the parts from moving to their idle positions.
