Claim Text:
1. An apparatus adapted for sealing bags selected from the group consisting of woven polymeric bags and multi-wall paper bags, comprising: a hot air manifold along which a bag is conveyed after the bag has been filled with contents and then closed; a hot air chamber of the manifold; the hot air chamber having first air passages, extending through a back wall of the chamber, to transmit hot air under pressure to heat at least a portion of a first adhesive layer on the bag to an adhesive state, and having second air passages, extending through a top wall of the chamber, to transmit hot air under pressure to heat a second adhesive layer on the bag to an adhesive state; the apparatus being adapted for sealing woven polymeric bags with the adhesive layers heated to adhesive states by the hot air of a reduced amount, wherein a hot air deflector covers selected said second air passages, reducing the number of second air passages for transmitting hot air of a reduced amount; and the apparatus being adapted for sealing a multi-wall paper bag requiring hot air of an increased amount for heating a corresponding adhesive layer to an adhesive state, wherein said hot air deflector is moveable and mounted to a position uncovering the selected said second air passages to increase the number of second air passages for transmitting hot air of an increased amount for heating a corresponding adhesive layer to an adhesive state, wherein fasteners attach the hot air deflector to the manifold, and the fasteners loosen for the deflector to move and uncover the selected second air passages to increase the amount of hot air under pressure through the top wall for heating a corresponding adhesive layer on a multi-wall paper bag.
