Abstract: Multi-section print material, such as a newspaper, is folded so as to enable inserts to placed at any location or at multiple locations within the half fold. Several sections are stacked onto one another with one of the signatures offset in the transport direction by a given amount. When the stack is subsequently half-folded, the protruding signature forms a lap which enables an insertion device to automatically insert at the lap position. The system may be operated in straight operation or collect operation. In one embodiment, the sections are transported in two web paths where they are cut into signatures. One of the web paths is delayed so that its signature arrives at the half fold gripper or pin cylinder slightly later than the signature from the other web path. The subsequently formed half fold has the trailing edge of the later-arriving signature protruding by a given lap amount that enables the downline inserter to insert at that position.
