ABSTRACT:
A helical conveyor system is disclosed. A conveyor belt 11 is positively driven by drive cage 21 around a plurality of vertically spaced helical loops. A pair of supplemental positive drives 25 and 26, which are driven at the same speed and synchronized with the drive cage, engage the belt 11 near its entry into and exit from the helical portion of its endless path. Vertical driving bars 45 on the drive cage 21 positively engage the cross rod heads 14 of the belt 11 in its helical path. The driving surfaces of the bars 45 are relieved at 61 and 62 to prevent driving engagement with the rod heads 14 over an inlet section of the first loop and an exit section of the last loop. The driving bars 45 also engage the ends of the rod heads 14 to limit the penetration of the driving bars past the edge of the belt.
