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.

Machine and methods for the manufacture of air-filled cushions

Devices and methods for forming air pillows are described. In accordance with embodiments of the invention, an apparatus for manufacturing air-filled pillows from a tube material includes a plurality of support rollers, a drive means, an injector means, and a sealing means. The plurality of support rollers support a roll of a tube material along an outer circumferential extent of the roll, in which the tube material includes two opposing sheets joined along at least one longitudinal edge thereof. The drive means draws the tube material from the roll along the support rollers, the injector means injects air into an interior space between the two opposing sheets of the tube material drawn from the roll, and the sealing means seals the two opposing sheets together with the injected air entrapped in the interior space therebetween.
