ABSTRACT:
Preparatory to closing a filled upright sack by a zig-zag closure, grippers engage the flattened mouth end of the sack. A support is swung to a position adjacent the flattened end and swing arms cause the end to be folded onto the support. After rollers have been swung onto backing rollers to clamp the folded-over end, the grippers are opened and withdrawn by the swing arms.
