ABSTRACT:
Machine and method for making air-filled packing cushions from a roll of prefabricated film material having a longitudinally extending inflation channel near one edge of the material and chambers which communicate with the channel through laterally extending passageways. The roll rests on a pair of spaced apart, horizontally extending rollers. The film material is fed from the roll to an inflation tube which extends into the inflation channel, air is introduced into the chambers through the inflation tube to inflate the cushions, and a longitudinally extending seal is formed across the passageways between the channel and the chambers after the cushions are inflated.
