Patent ID: 8905110

Claim:
A machine for the production of air filled cushions, comprising: a drive mechanism that moves layers of plastic through the machine along a predefined path; a film holder configured to hold a supply of the layers of plastic, the holder located so that drive mechanism draws the plastic film from the supply holder along the path; an injector having an outlet located adjacent to the path that injects air between the layers so that the drive mechanism moves the layers with respect to the injector; and a sealing mechanism comprising first and second sealing portions having an operating position in which the sealing portions are disposed on opposite sides of the layers in the path and pressed together thereagainst to provide sufficient pressure for sealing the layers together to seal off the injected air; wherein the first and second sealing portions are associated to move between the operating position and a standby position, in which standby position the sealing portions are separated from each other, releasing the layers of the plastic in the path, and the drive mechanism is associated with the sealing mechanism to move together between the operating and standby positions.
