  • Deformable side seal for furnaces and method for using
    Patent number: 5085680
    Abstract: A longitudinally extending row of closely spaced elongated flexible springs extend over an elongated slot of a furnace to prevent heat loss. The springs are deflected in turn as an arm moves along the length of the slot and the springs return to their original state after the arm passes by. The arm holds a glass handling device which holds a glass sheet within the furnace. The arm moves along the length of the slot so as to transport the glass sheet through the sections of the heat treating furnace.
