INVENTOR: KONRAD AUF DER MAUER INVENTION: APPARATUS FOR FORMING A GAP IN AN IMBRICATED STREAM OF SUBSTANTIALLY FLAT PRODUCTS ABSTRACT OF THE DISCLOSURE A first conveyor is adjoined downstream, as viewed in a predetermined conveying direction for an imbricated product stream, by a gap-forming device. A gap is formed in the imbricated product stream by means of the gap-forming device which feeds the imbricated product stream to a second conveyor. The gap-forming device comprises a belt conveyor provided with two laterally spaced transport belts, as well as an accelerating conveyor arranged between the two transport belts. A conveyor belt of the accelerating conveyor comprises passages which are distributed over approximately one half of its length. At the region of the conveying-active path of the conveyor belt, the passages are in connection with a suction trough. In order to form a gap in the imbricated product stream, the conveyor belt is driven at a higher speed than the belt conveyor, and the suction trough is connected to a negative pressure source. As a result, the products lying on the accelerating conveyor at the -1- beginning of gap formation are sucked onto the conveyor belt and accelerated by the latter, while the following or trailing products are further conveyed at a lower speed by means of the belt conveyor. -2-
