Abstract: A rotating stitcher 4 for driving U-shaped wire stitches 43 into printed products 3 being conveyed along a linear path, wherein a stapling closing device 5 cooperates with the stitcher 4, for closing the wire stitches 43. The rotating stitcher 4 has stitching heads 7 which are hinged around a rotating support 6. A control device guarantees that the stitching heads 7 are swung into a position where the direction of displacement E of the stitch plunger 10 is at right angles to the direction of transport A of the products 3 to be stitched. This takes place before or during entry of the stitching head 7 into the stitching area. While the wire stitches are driven in and stitched, the stitching heads 7 are held in this position and thus move linearly in the stitching area. The heads 32 of the stapling closing device 5 are guided in the same way, so that they move linearly during stapling, just like the allocated staple head 7.

A self-enclosed track of travel for stapling heads extends around a collector drum having a plurality of supports. A stapling head is assigned to each support. The stapling heads rotate mutually synchronously about the axis of rotation of the drum. While running past a wire section dispenser, each stapling head accepts a wire section from which a staple is formed in a predetermined first region. In a second region, the staple is brought onto the side of the stapling heads facing the supports. In a third region, the stapling heads are lowered onto the printed sheets, which are deposited onto the supports, and stapled together.

Abstract: The stitching or stapling heads, which act together in a stitching zone (C) with the supports that carry printed products to be wire-stitched, have a circular orbit. The stitching heads are guided so as to maintain their more or less vertical position during their orbit. Within the stitching zone (C), each stitching head is thus approximately aligned with its respective support and is therefore in the preferred position for driving the staples into the printed products. When the stitching heads encounter the supports, they are pushed back radially inward against the resistance of compression springs. This causes a slight flattening in the orbit of the stitching heads in the stitching zone (C) and slightly prolongs the time available for the stitching heads to act together with the supports in the stitching process.

Likewise, the stud magazine continually supplies studs from a stud hopper to the stud transfer wheel, which in turn continually supplies studs to the stud die wheel. The eyelet or stud is held on the die of the die wheel and the stripper of the transfer wheel by a vacuum. The vacuum is applied from a vacuum source through ports in each wheel to the die or stripper interface with the eyelet or stud. The vacuum in a transfer wheel operates from the point it receives an eyelet or stud from the magazine until the point where the eyelet or stud in transferred to the die wheel.

Abstract: A chain link type stapler operates in transit at about 45,000 items per minute to staple and crease printed paper products. Only two link chains are required and they have a common contiguous path for receiving and clasping the paper products for transit while being stapled by means of mating, stapler and anvil links. The stapler link operates to receive wire lengths, form staples therefrom, insert and clinch the staples over a cyclic path of the chain. This is achievable by means of a reciprocating wire clip assembly journalled in an internal cavity of the stapler link. Reciprocation is programmed by a cam arm extending externally from the clip assembly and stapler link on which roller means is mounted to ride in a cam track about the chain travel path.

The cams extend in parallelism with the path of signatures at the stapling station.

Abstract: In a staple wire supply system for use in connection with printing machinery or the like and of the sort having a fixed wire guide pipe past whose outlet end a knife is moved for cutting the wire down to the size needed for stapling, the time needed for the operation of changing over to a new reel of wire when one reel has run out may be greatly cut down by so designing the system that two reels may be supported thereon at a time and having a unit for running one wire from one such reel to the guide pipe and guiding the other wire into a ready or waiting position. Between this unit and the guide pipe there are two wire driving parts, such as pinch rollers acting on opposite sides of a capstan, which may be changed over in direction and may be used for moving wire from the two reels in oposite directions at the time of reel changing.

Abstract: Three adjacent continuously running chain link assemblies having two contiguous common paths, respectively in those paths (1) form staples from lengths of wire and (2) insert and clench the staples while creasing a signature passing through the linear path defined by the contiguous chain links.
