ABSTRACT

Disclosed herein are embodiments of a spiral conveyer belt system. Embodiments
of the system allow for a longer compressed pitch and improved
engagement/disengagement interactions between a drum and an inner edge of a
spiral conveyor belt while maintaining necessary product support and belt
support strength. In part, the disclosures relate to a grooved,
"ribless" cage bar cap, wherein grooves extend below an outer-facing
surface of the cage bar cap and are configured to engage with a belt support
rod inner-end or a belt-link tab. The bar cap groove may be straight
(generally orthogonal to the outer-facing surface) or angled to better engage
and drive the belt so the belt cannot slip forwards or outwards with respect
to a drum outer boundary.
