Abstract
Apparatus and method for controlling the speed of the conveyor on which a stack of sheets is being collected. A first conveyor moves a stream of sheets into a stacker and onto a second conveyor which moves the stack away from the incoming stream. The stream is moved around a drum which forms a part of the first conveyor and a second conveyor receives the stack and moves at a speed which accommodates the growth of the stack. A sensor detects the thickness of the stream of sheets, and another sensor detects the speed of the first conveyor, and the two sensings are transmitted to the drive for the second conveyor so that the second conveyor is moved at an automatic and appropriate speed to accommodate the incoming stream of sheets.
