ABSTRACT:
Apparatus for stacking and jogging cut sheets or carton blanks continuously includes a pair of side-by-side chambers comprising two side walls and a central divider panel and being open at the front, rear, top and bottom. A U-shaped elevator is disposed in each chamber and means is provided for raising and lowering each elevator individually. A plurality of vertically disposed, spaced stop fingers are mounted at the front of each chamber for outward swinging movement as a unit to permit removal of stacked blanks but normally operating as fixed stops for the blanks being fed to the chamber. Each chamber has a pair of vertical jogger plates and a motor, lever, linkage and pivot mechanism reciprocates one of the jogger plates toward and away from the divider panel and the other jogger plate toward and away from the stop fingers. A rod gate mechanism is disposed forwardly of the fingers and is swingable inwardly from a vertical to a horizontal position to hold the stream of blanks elevated while the already stacked blanks from the chamber are removed.
