Abstract
An endless conveyor belt has a thermal fluid (gas or liquid) sprayed against a portion of its underside to define a temperature-controlled region of the belt. To prevent the lateral escape of the thermal fluid, stationary seals are provided which contact the belt underside adjacent respective longitudinal edges of the belt. To keep the seals in continuous contact with the belt, despite warping that might occur, the seals carry magnets, and the belt is formed of a magnetizable material. Hence, the magnets force the belt and seals together.
