ABSTRACT:
A can stacking infeed machine for stacking nestable extruded cans where can diameter is greater than can height, includes a pair of gravity chutes for dividing an elevated stream of cans at input into two streams of cans, one above the other at output. A rotating starwheel collocates the cans sliding down the chutes one above the other for discharge in vertically registering pairs. A leaf spring mechanism urges the bottom of the upper can into nested engagement with the top of the lower can as the starwheel rotates releasing the cans to slide from the machine. Normally open switches located for sensing the flow of cans down both gravity chutes interrupt rotation of the starwheel thus preventing discharge of a single can from either chute. Stacked can pairs are accelerated upon release by the rotating starwheel as they slide from the machine to provide spacing.
