Abstract (en)

[origin: EP0497002A1] The gap-forming device (12), by means of which a gap is formed in the stream of overlapping articles (S) and which feeds the stream of overlapping articles (S) to the second conveyor (14), is located downstream of a first conveyor. The gap-forming device (12) has a belt conveyor (24) with two transport belts (26) located adjacently with a gap in between, and an accelerating conveyor (30) disposed between these two. The conveyor belt (28) of the accelerating conveyor (30) has openings (42) over approximately half of its length, which connect with the suction trough (44) in the vicinity of the conveying strand (28'). In order to form the gap, the conveyor belt (28) is driven at a higher speed (v2) than the belt conveyor (24), and the suction trough (44) is connected to a vacuum source. The products (48) lying on the accelerating conveyor (30) at the beginning of the gap formation are thereby sucked onto the conveyor belt (28) and accelerated by this, whilst the subsequent products (48) are transported further by means of the belt conveyor (24) with the slower speed (v3). …<IMAGE>…
