The invention concerns a machine for making air cushions for packaging from a tubular film (1) arranged on a reel, comprising spacing means (3) provided inside said tubular film to space the walls thereof, driving means (8) for pulling the tubular film and an inflating and welding device (5, 6, 7) having at least one hollow needle (5) for inflating. Said machine further comprises pinching means (2) for pinching said film to prevent air from moving towards said reel, that is upstream. Said pinching means (2) are located between the spacing means (3) and the reel, and the inflating and welding device (5, 6, 7) is located after the spacing means (3) and before the means (8) driving said film so as to pull the tubular film through the inflating and welding device. |
