FIELD: packing industry.SUBSTANCE: device comprises at least one reserve of a film, a film-feeding head and a tightening device. Besides, the film is fed from the film reserve to the head made as capable of displacement both in direction of wrapping and against the wrapping direction. Besides, between the film reserve and the head there is an accumulator installed to collect or accumulate the film as the head is moving, and the head and the tightening device are arranged as capable of displacement only along two vertical supports. The method of this device operation consists in the fact that the film fed by the head is pulled with the tightening device above the stack of products, besides, the head is displaced in direction of tightening. At the same time as the head is moving, the film is collected or accumulated in the accumulator arranged between the film reserve and the head.EFFECT: group of inventions provides for simplification of maintenance and reduction of labour intensiveness.15 cl, 9 dwg |
