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.

Abstract: A modular belt constructed of belt-edge modules that include slide bodies that slide along recesses in base module bodies. Slide cam surfaces on the slide bodies' hinge elements interact with base cam surfaces on the base module bodies' hinge elements of adjacent belt rows to move the slide bodies laterally as the belt articulates and de-articulates at its hinge joints. Optional clamp jaws on the base module bodies and the slide bodies are opened and closed by the sliding action. A belt with clamp jaws can be used as a cover belt for a conveyor belt with sideguards.
