Abstract
Overlapping cage-bar caps in a spiral belt conveyor. The cage bars of a spiral-conveyor cage are covered along the majority of their length by a main cage-bar cap fastened to the cage bar at the exit of the belt from the spiral. At the belt's entrance to the spiral, an entrance cage-bar cap overlaps a portion of the main cage-bar cap and the cage bar. The overlap is great enough to prevent a gap from forming along the length of the cage bar between the main cage-bar cap and the entrance cage-bar cap.
