Cylinders 17 are five pieces, they are intended to create a compressive force holding the product between the plates 14 and 15 clamping.
    Such constructive execution of the drive allows using one pump of moderate capacity to drive the cylinders 5 of both groups.
    For the strictly vertical movement of the plate 15, racks 19 with slots 20 are fixed on frame 6.
    The movable frame 6 is provided with water movement, which is made in the form of two one-way power cylinders 21 for moving the frame 6 towards the plates 1 and 2 of the press 3 and the power unit for moving the frame away from the press plates. The power unit for moving the frame in the direction from the press plates consists of symmetrically disposed two groups of power cylinders 22 to 23 of one-sided action, relative to the average thickness of the vulcanized product, similarly installed in the upper 15 and lower 14 plates of the clamp 13 parallel to each other and the working surface of the plates 14 14 and 15,

    The slides 33 are made with longitudinal grooves 36, in which protrusions 37 are installed, located on the lower surface of the angles 28, thereby providing communication between the sliders and the frame 6. In the upper wall of the guides 7 are made through grooves 38 for the passage of the protrusions 37. Synchronous movement of the sliders 33 and, consequently, keeping the frame in the right perpendicular direction of product selection, l coordination of operation of all power cylinders, the device can be equipped with electric, pneumatic or mechanical eskoy sound control system laziness. The device works as follows. The operation of the device is described in relation to its use in a press for vulcanizing a belt product such as a conveyor belt, having a reinforcement liner and covering it on both sides with layers of elastic polymeric material. To simplify the description, the work is given from the moment that the section of the conveyor belt located between the plates 1 and 2 of the press 3 has already been vulcanized and must be withdrawn from the zone of the plates of the press, and the next unvulcanized section of the conveyor belt must be inserted in its place. The plates 14 and 15 are pressed together and clamped between them the belts 4 and 5 and the section of the conveyor belt located between the latter. The pressure is applied to the cylinders 22 and 23, by which the frame b is moved along the guides 7 in the direction away from the press plates 3 while the heads 24 and 25 rest against their stock elements 26 and 27. Having moved, the frame 6 carries away the metal tapes 4 and 5 and a conveyor belt sandwiched between them. When the frame is moved along the guides 7, the sliders 33 associated with it move in the cavity 34 of the guides 7 in the same direction and interact with their gear racks 35 with the gear wheels 32, which ensures synchronous movement of the sliders and uniform movement of the frame 6 regardless of - pressure differences of the working medium in the cylinders 22 and 2. When the frame b is withdrawn from the vulcanized section of the conveyor belt in the direction from the plates 1 and 2 of the press 3, the next unvulcanized section of the conveyor belt is introduced into the gap between the plates 1 and 2. Thereafter, the supply of the working medium to the cylinders 22 and 23 is stopped and the supply of the working medium to the power cylinders 16, which raise the upper plate 15 of the clamp, begins. Simultaneously with this, the cavity of the cylinder 1 communicates with the reservoir of the working medium, therefore when the top plate is lifted, the working medium is also pushed out of the cylinder cavity 17. When the top plate 15 is lifted, the heads 24 of the cylinder rods 22 slide along the inclined face surfaces of the elements 26. After the start of lifting the upper plate 15, the frame 6 begins to move in the direction of the plates 1 and 2 of the press 3 when the working medium ejected from the cylinders 17 is fed into the power cylinders 21 and the polars 33 are moved in the cavity 34 towards Fig. 7 .. At the end of the frame retraction b, the closing operation of the plates 14 and 15 of the clamp 13 can be started when the working medium is supplied to the power cylinders 16. During lowering, the plate 15 interacts with the slots 20 of the uprights 19 and the heads 24 of the cylinder 22-current with the working surfaces of the protrusions 26. When the plate 15 interacts with the working branch of the metal tape, the working medium is supplied to the power cylinders 17, which create a force to clamp the tapes 4 and 5 and the conveyor belt located between them, sufficient to create a predetermined tension of the cured conveyor section tapes with cylinders 22 and 23 when fed to last pressures. Then the plates 1 and 2 of the press 3 are closed and the section of the conveyor belt in the working zone of the press is vulcanized. The process then repeats. Since cylinders 22 and 24 are arranged symmetrically with respect to the average plssiness of the vulcanized conveyor belt and force is applied to the frame in several, the conveyor belt is under the influence of a balanced pulling force, the resultant V of which lies on the middle plane of the belt and causes only tensile stress in the belt perceived reinforcing strip tape, not bending. This ensures the high quality of the product and reduces the metal intensity of the device while maintaining the proper rigidity of the structure. Claims of the Invention.
