Tapered drive bar apparatus

Abstract

The present disclosure relates to a drive bar apparatus for use in a helical conveyor system. In one embodiment, the drive bar apparatus includes at least one tapered drive bar configured to be mounted to a central drum of the helical conveyor system. Each of the at least one tapered drive bars includes a tapered tip having a conical outer surface for urging protrusions extending from conveyor belting to be engaged by the central drum to a first side or a second side of the at least one tapered drive bar. Each of the at least one tapered drive bars further includes a bar portion extending from the tapered tip and having a varying height which increases from the tapered tip to enable the bar portion to progressively increase engagement with the protrusions as the conveyor belting moves up the central drum.

Dependencies are inferred from the claim text.
