ABSTRACT:
An improved machine for welding pleats on fabric that employs a plurality of toothed wheels to index the fabric one pleat at a time. A pusher is positioned between each of a selected pair of adjacent wheels. The pushers are sized and configured to be capable of pushing selected pleats from the wheels to a proper position between the weld stack and anvil for welding. Additionally, the welding stacks are independently pneumatically actuated so that each welding stack may apply the proper welding pressure. A series of air blowers directs a flow of air under a just-welded pleat stripping it from the anvil.
