Abstract
A self stacking helical conveyor including a drum supported for rotation on a vertical axis, an endless belt trained about the drum in vertically successive helical tiers, beginning with a bottom tier, and having a width spanning a central load bearing portion and opposite side edge portions. The belt includes a plurality of successive conveyor sections interconnected for pivotal and translational movement relative to each other. Each of the conveyor sections includes a pair of spaced upstanding supports secured at the opposite side edge portions of the belt, each of the supports having a top detent formation. A bottom detent formation is provided under each of said upstanding supports. A supporting assembly is associated with the drum to support the bottom tier and the others of the helical tiers are supported by engagement of the bottom detent formations with the top detent formations on the spaced upstanding supports in an adjacent underlying tier of the belt.
