Abstract
Machine for inflating and sealing a preconfigured cushioning material which is wound in a roll on a hollow cylindrical core and has superposed layers of plastic film sealed together to form rows of interconnected, inflatable cells, a longitudinally extending channel near one edge of the material and inlet passageways interconnecting the channel and the rows of cells. The machine includes a rotatively mounted roll support shaft, a hub mounted on the shaft for engagement with the core at the end of the roll near the channel, a circumferentially expandable roll gripper for locking engagement with the inner wall of the cylindrical core, a feed mechanism for drawing the material and feeding it along a predetermined path, an inflator for injecting air into the cells, a nip roller, a pressing mechanism for pressing the nip roller against the roll of material, and a sealing mechanism for sealing the inlet passageways to retain the air in the cells.
