Abstract (en)

[origin: US4648586A] A gear folder for paper web ribbons utilizes four cooperating cylinders. The paper web is delivered between a cutting cylinder and a pin-holing and grooved bar cylinder where one or more cutting knives sever the web into signatures. The signatures are taken from the pin-holing cylinder by a collecting cylinder that is equipped with controllable pin sets. This collecting cylinder is operable in either straight, collect or double collect production. A bipartite folding blade cylinder, which has a slotted outer casing and a plurality of gear driven folding blades, receives the signatures from the collecting cylinder and causes them to be folded between opposed driven folding rollers. A section stitcher is cooperatively positioned adjacent the pin-holing and grooved bar cylinder.
