<p>A conveyor system for gripping and transporting plastic film is disclosed in the environment of a packaging machine and process for loading bags of a web (15) of side connected bags (25). The web is fed through a bagger section (17) by a pair of grooved main transport belts (40,41) and a pair of lip transport belts (48,49) each disposed in the groove (51,52) of the associated main belt to trap bag lips (38,39) in the grooves. Adjustable belt spreaders (61,62) space reaches of the transport belts as they move through a load station (60) whereby to sequentially open the bags into rectangular configurations. Alternate conveyor embodiments are also disclosed. The belts of each embodiment are constructed such that when force is applied to a gripped plastic film coaction of the film and belts causes the belt gripping of the film to tighten. <IMAGE> <IMAGE></p> |
