    The invention relates to the leather industry, namely, devices for stretching and plane drying of flat leathers and hides, the whole invention is an increase in productivity. The use of this device makes it possible, by drying the skin, to optimally increase its area or to treat already prepared skin, and its area will increase by a certain percentage. Fig. 1 shows an embodiment of a device for stretching and flat drying flat skin and hides, side view; FIG. 2 is the same, side view with square sheets} in FIG. 3 is a variant of the device in FIG. 1, top view; Fig. 4 shows a device with square sheets, top view; Fig, 5 is a variant of the device, side view; Fig, 6 - the same section. A device for stretching and flat drying flat skin and hides contains a mechanism for ensuring flat deformation of the semifinished product, having an elastic sheet 1 and means for stretching an elastic sheet nozzle 2 for connection to a vacuum system 3, facing the surface of the sheet, facing to the semi-fabricated catuct 4, and heaters 5 for drying the semi-finished product placed above the mechanism of dp for providing plane deformation. above the first plastic sheet parallel to it,) moreover, both sheets are made of an airtight material, and sharpening 7 located along the edges of the sheets and between them to seal the space between the sheets, while the means for stretching the elastic sheet is connected to the edges both sheets. The means for stretching an elastic sheet has hydraulic cylinders, snugs 8 or pneumatic elements. The tool dp for stretching the elastic sheet and one of the elastic sheets form together an endless conveyor belt 9. The device shown in FIG. 2 works by using two elastic airtight sheets 1 and 6, 433 having a round shape (FIG. 3), skin or skin ( semi-finished leather) 4 is inserted between both sheets (for example, so that the entire upper part of the device together with sheet 1 is removed up or to the side), then both sheets 1 and 6 are again joined, the space between the elastic airtight sheets This space is connected by means of pipe 2 to the vacuum system 3. Atmospheric pressure now press both elastic airtight sheets 1 and 6 to the semifinished product 4 "outside. The ropes are attached to the edges of both elastic air-tight sheets 1 and 6 which are guided through the diverter roller centrally to the hydraulic cylinder 8. One cable system is used for both elastic airtight sheets 1 and 6. By moving the rods of the hydraulic cylinders 8, the ropes 10 act on the edges of both elastic, airtight sheets 1 and 6 in such a way that the area of both sheets increases. Since the elastic airtight sheets 1 and 6, under the influence of atmospheric pressure, are pressed against the semi-finished product 4 on both sides, together with the sheets and the area of the semi-finished product being processed, this process can be repeated many times. When elastic airtight sheets 1 and 6 are returned to their original position, a vacuum is removed. When the sheets are pulled again, a vacuum is created inside the sealed space between the elastic airtight sheets 1 and 6. When drying the skin, heat energy is supplied to the leather semi-finished product 4, for example, with this arrangement, heaters 5 (infrared irradiation) , 2 and 4 elastic airtight sheets 1 and 6 are square in shape. The forces provided by the movement of the hydraulic cylinder rod 8, act directly on the edges of the sheets. Since the hydraulic cylinders 8 only act on the lower elastic air of the pressure-resistant sheet 6, the upper sheet 1 is mechanically stretched together with the sheet 6 at the edges. The sequence of operation corresponds to the sequence of operation of the device shown in FIG. 1. FIG. 3 shows the arrangement of the device in which the elastic airtight sheets 1 and 6 form an endless conveyor belt 9 among themselves. The leather semi-finished product 4 is laid and spread on one of the conveyor belts g9 and is then moved by movement of both elastic airtight tapes 1 and 6 into the zone 11 fixings. In this position, the leather semi-finished product is sealed by the ears 7 between the two elastic airtight sheets 1 and 6, the space between which is connected to the vacuum system 3 by means of the nozzle 2. By means of a rod of hydraulic cylinders 8, acting by stretching forces towards the edges of both ribbons, 434 tons of both ribbons, both in the longitudinal direction and in width. From the space between the two elastic airtight sheets 1 and 6 forming the conveyor, the leather semi-finished product 4 moves reciprocatingly in the horizontal plane. In this embodiment of the device, it is possible to supply thermal energy 4 to the leather semi-finished product 4 using radiator 5 or possibly in a sealed space formed by two elastic airtight sheets 1 and 6 and seals to form a high-frequency field. When the tensile strength is re-applied to the leather semi-finished product 4 by means of the rods of the hydraulic cylinders 8 during the drying process (due to the dynamic effect), the quality of the skin increases (its softness increases).
