Apparatus and method for arranging cartons or cases of beverages in predetermined patterns in a conveying process for stacking in tiers on pallets. A combination of an input guide conveyor moveable between left, right, and centered positions and at least one moveably adjustable diverter bar is utilized to direct incoming containers along a predetermined path through a pattern-forming zone comprised of a plurality of parallel, power-driven conveyors. Containers are directed one at a time either along a dividing line path between two, adjacent, pattern-forming conveyors in overlapping relation thereto, or directly onto one of those conveyors. A differential speed-control mechanism is provided in conjunction with one or more of the parallel, pattern-forming conveyors and is selectively actuated to change the speed of one conveyor of a pair of conveyors on which a container is being carried in overlapping relation to both conveyors. Such a conveyor speed change causes the container to be turned sideways and is utilized to orient containers in desired, alternate tier patterns for stacking on pallets.
