  • Method for manufacturing air filled packing cushions
    Patent number: 7497066
    Abstract: A machine (1) for the production of packaging material in the form of air filled cushions (24) comprises feeding rollers (2) for conveying parallel two films of plastic material (20a and 20b), unwound starting from rolls (30a and 30b), according to a conveying direction. Downstream of the feeding rollers (2) air is supplied between the two films (20a and 20b) by means of a plurality of tubes (6) extending from a collector (5) and parallel to the conveying direction of the films (20a and 20b). Each tube (6) extends between two longitudinal heatsealing elements (10), crosses a couple of dragging rollers (8) and ends at transversal heat-sealing elements (15).
