ABSTRACT:
A conveyance system comprises a production machine for manufacturing a web of packaging cushions, a duct downstream from the production machine, a blower to provide an air flow through the duct to apply a conveyance force for conveying the web of packaging cushions, and a friction contact area downstream from the production machine and upstream from the duct entrance. The web of packaging cushions passes beneath and contacts the friction contact area to create a friction force opposing the conveyance force so that the conveyance force is not transmitted along the web of packaging cushions to the production machine.
