ABSTRACT:
A device for use in conjunction with a sheet group separator of the type having a rotating slotted disk supporting a stack, together with a depressor for the lowermost group, and a finger for separating a corner of said group from the stack. The device comprises a vertically slidable weight at said stack corner so that a constant downward pressure is exerted to prevent upward curling of the corner which might reduce the effectiveness of the finger and depressor movements. A counterweighted pressure bar is pivotally mounted at the lower end of the weight so that placing additional sheets on the stack will not interfere with the operation. The weight is reset by pulling upwardly on a handle so that the pressure bar swings away to clear the new sheets and is swung back into position by the counterweight.
