Abstract
An offset stacker includes a frame and a movable tray which reciprocates within the frame between an upper stacking station and a lower discharge station. Sets of sheets or bound pamphlets are fed onto the tray and are urged against a fixed wall by a plurality of short patter fingers. A plurality of movable jogger arms is rotated onto the first set and the tray is indexed downwardly so that it may receive a second set which is urged against the jogger arms by a plurality of long patter fingers. The second set is offset from the first and held in position by a plurality of fingers while a third set of sheets is placed upon the second set and urged against the fixed wall by the plurality of short patter fingers. After collecting the sets into an offset stack, the tray is indexed downwardly to the discharging station where a conveyor device removes the offset stack of sets from the tray and presents it for removal from the stacker.
