Abstract
An apparatus adapted for sealing bags includes a hot air manifold along which a bag is conveyed after the bag has been filled with contents and closed. The manifold includes a hot air chamber having first air passages transmitting hot air under pressure to heat a portion of a first adhesive layer on the bag to an adhesive state, and second air passages transmitting hot air under pressure to heat a second adhesive layer on the bag to an adhesive state. A hot air deflector covers selected second air passages transmitting the hot air, wherein the apparatus is adapted for sealing woven polymeric bags with the adhesive layers. The hot air deflector is moveable to a position uncovering the selected second air passages to increase the amount of hot air, wherein the apparatus is adapted for sealing multi-wall paper bags.
