ABSTRACT:
A levitating paper stacking device for stacking different length papers. The device includes a box-like receptacle having a bottom wall, a front wall, and a pair of sidewalls, and a fold-down, four bar linkage, perforated ramp. The ramp is movable between a raised position for stacking a shorter length paper and a stored position for stacking a longer length paper. The ramp includes three hinged segments wherein the forwardmost segment constitutes the rear wall of the receptacle when the ramp is in its raised position and wherein the forwardmost and middle segments constitute an addition to the bottom wall of the receptacle when the ramp is in its stored position. The device further includes means for automatically moving the ramp to its raised and stored positions, and means for directing a levitating air flow toward the rearwardmost segment when the rearwardmost segment is in its raised and stored positions, whereby the different length papers are conveyed to the front wall of the box-like receptacle with a minimum of bounceback.
