Abstract
A device and method are disclosed for forming air filled cushions. The device includes a drive mechanism to move inflatable tubing through the apparatus, and an injector, optionally including an outlet, located continuously within, or within a portion of, the tubing. This arrangement can permit the formation of air filled cushions in a continuous stream. Also disclosed is a roll of plastic tubing that is sealed transversely at a succession of intervals, with each pair of seals stopping just short of a longitudinal center line of the tubing. Such tubing might be used in conjunction with the apparatus, the central gap between the seals allowing passage of the injector.
