Abstract:
A spiral conveyor for positively driving a conveyor belt along a helical path. The spiral conveyor includes a rotating cylindrical tower with parallel drive members extending from the bottom to the top of the tower on its periphery. Each drive member includes an outwardly protruding ridge that varies in height from the bottom to the top of the tower. The variations in height facilitate the belt's entry onto and exit from the tower and robust, positive driving engagement with the inside edge of the belt along the majority of its path along the tower.

Claim (Index 1):
A spiral conveyor comprising:\n a drive tower rotatable about a vertical axis and extending from a bottom to a top with a belt entrance portion of the drive tower at or near the bottom for an upgoing spiral or at or near the top for a downgoing spiral, the drive tower including:\n a plurality of parallel ridges projecting radially outward and extending in length at the periphery of the drive tower between the bottom and the top; \n wherein the parallel ridges taper outwardly away from the vertical axis toward the bottom for an upgoing spiral or toward the top for a downgoing spiral in at least a portion of the belt entrance portion; \n a conveyor belt positively driven without slip in a helical path around the drive tower by the parallel ridges engaging an inside edge of the conveyor belt.
