Abstract
An apparatus for inflating and sealing packing cushions has a drive mechanism for feeding a preconfigured film material to a sealing mechanism in a flattened state without wrinkles in the sealing region in which a longitudinal seal is formed. In one aspect, the drive mechanism comprises a pair of upper adjacent belts and a backing element, such as a lower belt. The sealing mechanism may be a rotary sealing wheel that contacts the film material between the upper adjacent belts.
