Abstract
Apparatus for simultaneously accumulating two stacks of paper sheets has a first conveyor which advances a series of sheets into the range of a first transfer member so that successive sheets are respectively adjacent the front and rear surfaces of the transfer member. The transfer member is reciprocable transversely of the path of movement of oncoming sheets, and each of its forward strokes is utilized to expel a sheet into a first stack forming station. Each return stroke of the transfer member is utilized to advance a sheet into the range of a second conveyor which transports sheets forwardly beyond the first stack forming station and into the range of a second transfer member. When the first transfer member performs a forward stroke, the second transfer member expels the foremost sheet from the second conveyor into a second stack forming station. The first conveyor has a first pusher which is moved cyclically along a first endless path to alternatingly advance successive sheets along the first path adjacent the front and rear surfaces of the first transfer member. A second pusher which is rigid with the first pusher, serves to advance successive sheets in the second path in front of the second transfer member.
