<p>One aspect of this invention comprises an improved conveyance system having an endless flexible belt (224) which circulates through at least two arcs, at least one gripping member (110) attached to the belt (224), the gripping member (110) having a free end (116) and an anchoring end (114), and a biasing member (432) which biases the anchoring end of the gripping member (110) toward the surface of the conveyor belt, wherein the gripping member is open as it traverses an arced path and is closed as it traverses a straight path. A workpiece (226) is loaded as the gripping member traverses the first arc, and offloaded as the gripping member traverses the second arc. Preferably, the first arc has a greater radius than the second arc. The invention also includes a heater (10, 12) utilizing the conveyance system.</p> |
