ABSTRACT:
Shingles or the like are usually rectangular in shape and of non-uniform thickness being of a greater thickness at one long edge and of lessor thickness at the other. Such shingles are arranged by automatic equipment for stacking in squared bundles by delivering the shingles one at a time successively and individually onto a pair of laterally-spaced movable shelves formed by a pair of starwheels. By intermittent simultaneous angular movement of both starwheels, or by intermittent angular movement of only the front starwheel while maintaining the rear starwheel motionless, a group (such as five) of accumulated shingles is dropped without flipping onto a transversely moving conveyor belt. By intermittent angular movement of only the rear starwheel while maintaining the front starwheel motionless, a group of shingles is flipped, i.e. turned over on to its other side. If the spacing between the starwheels and the moving conveyor belt is sufficient, the group of shingles will flip through 180.degree. without aid from the transversely moving conveyor belt. Where the spacing between the starwheels and conveyor belt is less, the group of shingles will not be completely flipped by the time it reaches the conveyor belt. In such case, flipping will be completed by the action of the conveyor belt moving in the same transverse directon as the transverse component of movement of the lower edge of the falling group of shingles. By stacking together in one bundle an equal, or approximately equal, number of flipped and unflipped groups of shingles, a bundle having substantially uniform height is obtained.
