ABSTRACT:
An apparatus which damps movement of sets of sheets being stacked on a support member. The support member moves, at selected intervals, to offset adjacent sets of sheets from one another. A pair of pivotably mounted arms have their free ends engaging the outermost sheet of the sets of sheets stacked on the support member. The arms apply a normal force on the sets of sheets without applying a lateral force thereon. In this way, the sets of sheets are damped without disturbing the integrity of the sets of sheets during offsetting.
