    Overlock 12 with two sewing machines (Figs. "1 and 2)" The plate has a lower contact surface of a material with a high coefficient of friction, which ensures the frictional retention of the part 10 when the latter moves along platform 9 with a low coefficient of friction o
    The method is carried out as follows.
    The part 1 is transported in the extended state by means of the feeding plate 7 to the described position on the table 2a.
    Then, using an air-suction unit, a vacuum is created, under the action of which the air-suction nozzles 15 suck up the elastic bands 13 and 13a, 14 and 14a using brushes 19 "Then the elastic bands 13 and 13a, 14 and 14a are gripped relative to the nozzles 15 by means of gripping clamps 31 which move to the gripping position (fig. 07-8) o After that, the suction nozzles 15 are moved in the axial direction away from the table 2 to tension the part, and then the clamps 17 interacting with the elastic bands 13 and 13a are brought into engagement with detail 1 in series with the indicated elastic bands by moving the grippers 17 to a position above and then down onto part 1 (Fig. 12). The fingers 18 of the means for stretching and leveling the part 1 interacting with the fixed table are actuated, while the other half of it folds about I
    After that, using the cylinder 4, the rotary segment 3 is activated so that it overlaps the table 2, and the two halves of the part 1 are superimposed and form the product 10 (Fig. 13) o
    The levers 27 are then actuated to grip the product 10 from the inside of the grippers 17, after which the grippers 17, the fingers 18 and the grips 31 interacting with the elastic bands 14 and 14a are released. After that, the pivot segment 3 returns, and the feed plate 7 is moved and positioned over the part 10 between the clamping levers 27 (Fig. 14). The levers 27 are then released and the part moves along the platform 9 to the two sewing magazines Overlock 12 for sewing together
    The feed plate 7 (Fig. 16) consists of a metal plate having such a shape that the part I protrudes beyond the edges 7a of the plate 7, which has opposite projecting surfaces 7c for guiding
    a large number of rollers associated with the previous working position (not shown) involved in stitching the respective opposite edges of the part 1 “Plate 7 has a large
    5 the number of cutouts 7c for reducing its weight and, in addition, two opposing pins with which the respective grippers interact to raise, lower and move the 7 "plate
