Abstract (en)
[origin: EP2143555A1] A machine (1) for making a packaging material in the form of cushions (100) of gas, for example cushions filled with air, comprises feeding rollers (21) that are adapted to bring a web (10) of thermoplastic material along a longitudinal feeding direction. The web (10) comprises, in particular two films (10a, 10b) that are overlapped to each other and can be unwound starting from a roll (50). The transversal welding lines (11) have in particular a length that is less than the transversal width (L) of the web (10), in order to define an open passageway (18) at which the web (10) is put on a longitudinal guide (25) that is arranged downstream of the feeding rollers (21). At the guide (25) a cutting blade (85) is present that cuts longitudinally the web (10) obtaining a longitudinal cut (14). This allows the introduction of an inflation member (27) and the movement of the web (10) along the machine (1).
