Abstract
Apparatus for feeding sheets one by one from the bottom of a stack of sheets comprising first and second spaced supports cooperatively supporting the bottom of a stack of sheets, the first support comprising a rotatable unit and the second support comprising a flat abutment member. The rotatable unit includes a plurality of juxtaposed rollers at least one of which is intermittently rotated to feed the lowermost sheet in the stack to a conveyor. The flat abutment member is adjustably supported for displacement to a selected predetermined stationary position. The rotatable roller is coupled to a suction device so that suction force is applied to the lowermost sheet in the stack in the course of intermittent rotation and the position of the roller with the conveyor belt is such that the suction will be substantially reduced when the sheet has been received by the conveyor belt.
