ABSTRACT:
A roller conveyor is designed to advance successive stacks of superimposed sheets of paper or the like against an abutment. The lowermost sheets of the stacks tend to slide relative to the sheets above them, and such tendency is counteracted by constructing the roller conveyor in such a way that its major section, which is spaced apart from the abutment, advances the stacks with a first force and the next-following section thereupon advances the stacks with a greater second force. The conveyor has driven shafts which extend transversely of the direction of advancement of the stacks and are surrounded, with play, by ring-shaped or hollow cylindrical rollers which contact the undersides of lowermost sheets of the stacks.
