ABSTRACT:
Heat sealing apparatus is provided in which a heat seal head defines longitudinal slots which underlie a wire heating element and communicate with a cooling fluid path to provide rapid cooling to the heating element. The longitudinal slots have a width that is narrower than the width of the wire to provide wall supports on opposite sides of the wire.
