Abstract: A dual web, intermittent motion packaging machine consisting of two webs being pulled by a dual web feeder roller unit through a dual side heat sealing device and a dual bag cutting device for forming two sets of bags. The dual web feeder roller device is driven by an assembly of new shafts, clutches, electromagnetic brakes and gears so as to provide for adjustment in pulling the dual webs. The web feeder roller units are adjusted to main synchronization between the two webs. The bags are carried by a dual bag clamping device attached, preferably, to an endless horizontal indexing chain.
