APPARAT ZUR HERSTELLUNG VON PNEUMATISCH GEFÜLLTEN VERPACKUNGSKISSEN |
摘要 |
System, method and material for making pneumatically filled packing cushions in which a plastic film material having two superposed layers joined together along first and second longitudinal edges is prefabricated at a first location by forming longitudinally spaced, transversely extending rows of perforations across it and sealing it together along seal lines which extend from the first edge of the material in a direction generally parallel to the rows of perforations other and terminate a short distance from the second edge to form chambers with open mouths facing the second edge between the rows of perforations. The material is then fan-folded or formed into rolls for storage and shipment. At a second location, gas is introduced into the chambers by passing the material along a tube positioned between the ends of the seals and the second edge of the material and injecting the gas into the open mouths of the chambers through openings in a side wall of the tube. The two layers are then sealed together across the open mouths to close the chambers and retain the gas in them. |
