Abstract: A conveyor mounted bag gripper coacts with a bag foldover forming blade to fold over a flexible plastic film bag just formed at a bag bottom sealing-cutting station in a bag manufacturing operation, closes to grip and hold the folded over bag, strips the folded over bag from the forming blade as it travels with the conveyor to a bag stacking station, and then opens to release the bag at the bag stacking station.
