Abstract: A modular spiral belt constructed of a series of hingedly interconnected belt modules arranged in a helical stack. The modular spiral belt includes outer side plates (50) that include openings for airflow and inner side plates (80) that are solid to block airflow. The openings may include valves for selectively opening and closing the openings. A locking mechanism may lock two tiers together. A hold down may apply pressure to prevent destacking of the belt or a guide may be disposed with the helical stack for preventing destacking.

Abstract: A spiral conveyor for positively driving a conveyor belt (20) along a helical path. The spiral conveyor includes a rotating drive tower (180) with parallel drive members (14) extending from the bottom to the top of the tower on its periphery. Each drive member includes an outwardly protruding ridge (28) 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. In another version, a conveyor belt has teeth (62) with guide surfaces (78,79) at the inside edge of the belt. The teeth guide the drive members between belt rows into driving engagement with drive faces at the inside edge of the belt.

Abstract: A sectional article transfer assembly for receiving articles stripped from the conveying surface of a moving conveyor belt. The article transfer assembly includes, as a first piece, a transfer edge member having a base portion lying on and supported by a support frame and a belt-abutting portion that extends from the base portion to closely abut the conveying surface of a conveyor belt as it passes around a sprocket. The belt-abutting portion can have fingers or a beveled straight edge, for example. The transfer edge member mates with a second piece, a transfer plate member, which has a recessed portion that overlaps and mates with the base portion of the transfer edge member and a flat top article-transfer plate continuous and coplanar with an upper surface of the transfer edge member to form an extension of the conveying surface of the belt along which articles arc conveyed. In preferred versions, the two pieces can each be made of different materials, such as a durable material for the transfer edge member and a low-friction material for the transfer plate member. Other combinations of materials can be used to adapt the characteristics of the sectional transfer assembly to different operational demands.
