ABSTRACT:
A method for the continuous formation of a stack of folded products standing on edge includes feeding folded products to a stack of folded products standing on edge. The stack is moved forward with a conveyor belt at a speed being matched to the feeding of the folded products to the stack. An interruption in the continuous feeding of the folded products to the stack is detected. A separating device is activated. The conveyor belt is stopped for the duration of the interruption. A device for the continuous formation of the stack of folded products includes a device for feeding the folded products in a stream to a stack of folded products standing on edge. The stack is moved forward on a conveyor belt at a speed being synchronized with the feeding of the folded products to the stack. At least one separating device contacts the folded products. A sensor monitors the stream of folded products and supplies output signals. A logic unit is connected to the sensor for recognizing an interruption in the stream of folded products from the output signals of the sensor. The logic unit is connected to the conveyor belt and to the at least one separating device for activating the at least one separating device upon the occurrence of an interruption in the stream and for stopping the conveyor belt for the duration of the interruption.
