Abstract
This relates to a drive system for selectively positioning a heat sealer and a cooler relative to mandrels supporting bags or pouches, which mandrels are carried by a turret and indexed thereby. A simple oscillating shaft driven by a cam oscillates a double ended lever which, in turn, serves to oscillate wedge shaped cam members so as to simultaneously actuate two sets of heat sealers and coolers with each heat sealer and cooler being carried by a separate support arm.
