ABSTRACT:
A shrink oven whose air volume is maintained constant as heated loads are removed and new loads are introduced, to prevent loss of heat and to improve performance. In an oven in which loads are introduced through an entry opening, move through the oven, and exit through another opening, exiting and entering loads are moved so that the rate of load displacement out of the oven at the exit is compensated by the rate of load displacement into the oven at the entry. Special arrangements prevent hot air loss around the sides of the load during the exit and introduction phases. These include close-lying passage walls above and on both sides of the openings, for limiting the air conductance of the gaps about the loads, stacking adjacent loads close together at entry and exit to minimize air leak gaps between the loads, and close positioning of the loads next to doors during opening and closing of doors.
