The present invention concerns a machine for converting a web of preformed pouches to dunnage units. The pouches are defined by transverse seals that extend from a remote edge to within a predetermined distance of an inflation edge. In a first embodiment, the machine includes a guide pin, a drive, a blower, and a sealing element. The guide pin is insertable between the transverse seals and the inflation edge. The guide pin defines a path of travel of the web. The drive moves the web along the path of travel. The blower is positioned with respect to the path of travel for inflating the preformed pouches. The sealing element is positioned to provide a longitudinal seal that intersects the transverse seals to close the preformed pouches and form inflated dunnage units. The disclosed examples of machines for converting a web of preformed pouches to dunnage units including various improvements to existing machines.
