Abstract
A machine for converting a web of preformed pouches into inflated dunnage units. The pouches are defined by transverse seals extending from a remote edge to within a predetermined distance from an inflation edge. The machine includes a tensioning device for frictional engagement with the web, an inflation arrangement for inflation of the preformed pouches, a sealing arrangement, and a clamping arrangement. The sealing arrangement may be positioned to provide a longitudinal seal that intersects the transverse seals to close the preformed pouches and form a dunnage unit. The tensioning device holds the web taught during downstream travel.
