ABSTRACT:
A device for facilitating stacking of sheets in a hopper of a sheet transporting apparatus in which sheets are directed seriatim onto a stack of sheets in the hopper and subsequently fed seriatim from the stack of sheets in the hopper. The facilitating device comprises at least one elongated member supported at one end thereof for substantially free pivotable movement in a vertical plane under the influence of gravity. The support for the elongated member is located to particularly position the elongated member whereby a sheet directed onto the stack in the hopper will strike the elongated member. The elongated member absorbs kinetic energy of the directed sheet to stop such sheet movement and pivot the elongated member in a first direction about the support and, when the elongated member pivots in the direction opposite the first direction under the influence of gravity, the elongated member strikes the sheet to urge the sheet into accurate operative engagement with the sheet feeder.
