An article infeed unit includes a plurality of carrier pocket devices movable to and away from an article delivery station, and a confronting receiver pocket is mounted at the delivery station. The receiver pocket has upstanding sides, and the sides are partly defined by vertical margins confronting the carrier pocket. On demand, a spreader cam operates to spread the receiver pocket side margins apart from one another, so as to accommodate passage of the articles from the carrier pocket into the receiving pocket. At the bottom of the receiving pocket, a base plate is inserted, and the inserted articles rest upon this base member. After the spreader cam is withdrawn, the receiver pocket sides close around the articles. Thereafter, the base plate is withdrawn, and the received articles to descend through the receiver pocket toward a processing device.
