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.
Claims22
A conveyor for transporting successive objects of a series of objects in a predetermined direction and along a predetermined path toward an abutment, comprising:
- a first section spaced apart from said abutment and including means for advancing the objects in said direction with a first force;
- and
- a second section disposed between said first section and said abutment and including means for advancing the objects in said direction with a second force greater than said first force.
A method of conveying successive stacks of superimposed sheets in a predetermined direction and along a predetermined path toward an abutment, comprising the steps of:
- conveying the stacks with a first force along a first section of said path remote from the abutment;
- and
- conveying the stacks with a second force, greater than the first force, along a second section of said path between the first section and the abutment.
