  • Patent number: 7980541
    Abstract: A device for distributing successive products of a product flow, particularly the successive folding products produced by a cross cutting device by dividing a material web, to two branch flows, with a wedge arrangement which is arranged in a stationary manner in the transporting plane of the product flow and which engages between two cam rollers which flank it and which are arranged symmetrically with respect to the center working plane. The device is characterized in that the wedge arrangement engages between two guide plates which flank it and which, together with the wedge arrangement, define a path fork. The guide plates have slots through which they are alternately penetrated by cams of the respective adjacent cam roller which are associated with the slots, so that the penetrating cams and the guide plate which is not penetrated form a feed for a belt guide associated with a branch flow.
