ABSTRACT:
An apparatus for stacking thin objects which are delivered by a conveyor to a rotary drum having holes over its periphery extending to the interior and a fixed body within the interior having a plurality of chambers communicating with the holes over a half circumference. Valves connecting to the chambers are operated to successively connect the chamber to a vacuum source so the object is engaged and rotated with the drum and then to successively connect to a pressure source to produce a blowing action moving the object toward a stack.
