ABSTRACT:
A sheet stacking method and apparatus having conveyor belts for feeding overlapping cut sheets of cardboard in a flow to a stacking station, in which in order to form a gap in the flow a second conveyor belt is driven faster than a first conveyor belt and, during the time the second belt is driven at the faster rate, a third conveyor belt lifts the sheets off the second belt and drives them at the same speed as the first conveyor belt until the sheet downstream of the gap has left the second belt, whereupon the second belt is again driven at the same speed as the first belt and the third belt replaces the flow of sheets onto the second belt.
