Abstract
Apparatus for grouping articles in stacks of a predetermined number in which a wheel having serrated teeth picks off articles from the base of an infeed chute and places them on edge on a pair of inclined rails. The articles are held to the wheel by vacuum and are separated from the wheel by wedge members positioned adjacent the rails. A stack of articles builds on the rails and is slid into a conveyor bucket. After each predetermined number of articles is removed from the chute, a lever is actuated to hold the column of articles in the chute out of contact with the teeth to allow for advancement of the bucket conveyor.
