The machine can be used in the light and food industries and in agriculture. It guarantees high quality packaging without any damage to the product, economy of power and reduced noise during operation as well as high productivity. The machine consists of a frame (1) on which a lower and an upper drum (2 & 3) are mounted containing heat shrinkable foil, an electric motor with a reducer (4) driving a nest-type conveyor belt (5) over which an adhesive device (7), upper roller unwinding device (8), heat chamber (9) and cooling station (10) are mounted. The adhesive device (7) consists of a upper supporting beam (11), enclosed by a clamping device (12) connected to it by adjustable bolts (14) having springs (14). A heating filament (16) is stretched under the beam (11) under which filament (16) there is a resin-dipped fabric liminate bus having a longitudinal chute (18) mounted to an axle (19) connected by bearings (20) to connecting links (17) and elliptic cams (21). Gears (22) are driven together with gears (23) by chains of the nest-type conveyor belt (5). The one end of a sensing bar (26) is fitted to the conveyor belt (5) by means of a plate and a rubber pad (25), its other end being fixed into slot (27) in contact with a track switch (28)./!
