phage 1. The invention relates to the production of roll materials, for example fiberglass, from raw materials, the processing of which is accompanied by squeezing at normal or elevated temperature. There are known devices for the manufacture of roll materials, comprising drive and tension drums, partially enveloped by a conveyor belt, as well as nodes for the supply of raw materials and the delivery of finished products. In these devices, the relatively low pressure limit of the pressing is due to the applied pressure member, as well as the impossibility of applying stepwise pressing (prepressing), as an important part of the technological process, which improves the parameters of the finished material and reduces the duration of the production cycle. Compression takes place between flax and drum due to belt tension. The relatively low tensile strength of the tape limits the pressing force, and the double-sided bending of the tape during press operation limits its durability. The proposed device differs from the well-known in that the drive and tension drums, as well as the nodes for the supply of raw materials and the delivery of finished products, are mounted inside a contour limited by a transport belt. This ensures the compactness and durability of the device. In order to increase the pressing force of the material, the conveyor belt can be additionally pressed to the drive bairaban with the help of another external tape, which is pulled on a separate tension drum. In such a device, it is advisable to carry out the outer tape of the turns of the cable located close to each other. In Fig. 1, the proposed device is shown, a general view; on the league, 2 section aa of fig, 1; on fig.Z - section b-In figure 1; figure 4 is a view along arrow B in figure 2. The device consists of a frame 1 on which the drive 2 and traction drums 3 and 4 are mounted, the conveyor belt 5 and the outer belt 6 are made of cable turns, the final product output unit 7, the raw material supply unit 8, tension device X (e.g. hydraulic system), drive 10 and heaters 11. Heated drum 2 is rotated by drive 10. Drum 3 is also heated and moves closer to drum 2 or moves away from it using a tensioning mechanism. The drum 4 has a similar tensioning device. The tapes 5 and 6 can be made of steel strips of appropriate width or (as shown in FIG. 2) from one or more steel tapes 5 and a steel or other high-strength cable 6 folded into a flat endless tape, the ends of which are attached to adjacent turns in a known manner as shown in FIG. four . The number of drums in the device and the corresponding number and combination of tapes in the press package are chosen in accordance with the structural requirements. Tensioning mechanism 9 carries out separate tensioning of each drum 3 and 4 by an effort determined by technological requirements, and also regulates the course of the tapes along the drums. The presence of a number of drums and their corresponding location make it possible, in combination with a package of compression tapes, to exclude double-sided bending of tapes during the operation of the device. In this case, the drum 2 is acted on by forces equal to the sum of the forces from all the belts of the package, and on the drums 3 and 4, respectively, from each belt individually. In order to reduce the overall dimensions of the device, the nodes 7 and 8 of the output of finished products and the supply of raw materials are placed in the space between the drums and the tape package, Procurement, for example, of fiberglass canvas (fabric) impregnated with resin, or friends; the material from the node 8 enters the drum 3. By the force of the tape 5, the material is pre-pressed (pre-pressurized) and heated. Then, together with the tape, it enters the drum 2. By the tension generated by the tapes 5 and b, the material is finally pressed. After this, the material comes off the drum 2 and goes to the node 7. Depending on the composition of the starting materials, the device Cuget to produce the finished product, the semi-finished product for further refinement, for example, copolymerization in special chambers, a material with a textured coating, etc. specified by the program. The temperature of the material in the area between the drums 2 and 3, as well as above them, is maintained by the heaters 11. The significant dimensions of the diameters of the drums 2,3 and 4 (for example, 1200 mm and more allow the device to be loaded with the workpiece and removed the finished product.
