ABSTRACT:
A bagging machine comprising an article discharge chute for releasing one or more articles in an open bag held thereunder at a bag loading position. A plurality of collapsed plastic bags are supported under and adjacent the discharge chute. The mouth of an outer one of the plastic bags is opened with a bag opening clamp and the rear and front wall of the bag are held spaced apart so as to receive one or more articles therein through the discharge chute. Bag holding and stretching fingers grip the bag at opposed upper side edge portions thereof whereby to transfer the first bag filled with the articles to a sealing station after the front and rear walls of the bag are detached from their bag opening securement. At the sealing station, a clamp engages the stretched rear and front walls together below the mouth opening and the rear and front walls together are sealed across the mouth opening above the clamp after release and removal of the bag holding and stretching fingers to effectuate a substantially crease-free seal entirely across the mouth opening of the bag.
