Abstract
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.
