ABSTRACT:
Machine for inflating and sealing a preconfigured cushioning material which includes a rotatively mounted roll support shaft having a fixed end and a free end, a hub mounted on the shaft near the fixed end for engagement with a cylindrical core at the end of a roll of film material, a circumferentially expandable roll gripper at the free end of the shaft for locking engagement with the inner wall of the core, an inflator having a conically tapered tip and a plurality of outlet openings for injecting air into cells of the film material, a nip roller pressing against the roll of film material to limit the flow of air into the cells of the film material on the roll, and sealer for sealing the inlet passageways to retain the air in the cells.
