ABSTRACT:
Stacks of paper sheets wherein a first marginal portion of a relatively large second sheet extends beyond the corresponding first marginal portions of two piles of relatively small first sheets, wherein the second sheet is disposed between the two piles of first sheets and wherein at least some first sheets are often out of exact alignment with the remaining (aligned) first sheets are treated in an apparatus wherein an inclined first surface supports one side of a stack and a second surface at the lower end of the first surface is provided on a stop for those (second) marginal portions of the sheets which are remote from the first marginal portions. The misaligned first sheets are moved into exact register with the remaining first sheets by shifting them toward the second surface so that their second marginal portions contact the stop. This is accomplished by resorting to abutments which contact both sides of the first marginal portion of the second sheet and are movable toward the second surface to engage the first marginal portions of misaligned first sheets and to move such sheets toward the stop. The abutment at one side of the first marginal portion of the second sheet is movable into deforming engagement with the adjacent section of such first marginal portion to deform the second sheet prior to shifting of misaligned first sheets toward the stop.
