Abstract: A method for continuous quality control of geometric, structural and functional parameters of an applied element, such as a staple, in printed products. The quality control is realized with the aid of at least one measuring device that comprises at least one measuring head including at least one permanent magnet and at least one giant magneto resistance sensor chip. The applied element is detected with the measuring head and, based thereon, a magnetic image is generated of the condition of the element.

Abstract: A device for removing printed products, having a fold and being transported uniformly spaced and astraddle by a transport device, has a rotatingly driven gripping device with controlled gripping elements for gripping one of the printed products by the fold on the transport device and removing the printed product while stably holding the printed product. The rotatingly driven gripping device has control elements for controlling an opening movement and a closing movement of the gripping elements and is adjustable for adaptation to the different thicknesses of the printed products during running.

Abstract: Signatures are transported straddling on a saddle-shaped support of a conveying device by circulating drivers and are removed by means of a blade of the conveying device and are transferred to a lift-off device. The conveying device is lowered in the region of blade and the drivers push the signatures onto the essentially fixed blade. As a result of the conveying device being lowered in the region of the blade the drivers dip down after the signatures are pushed onto the blade and no longer grip the signatures.

Abstract: A gathering and stapling machine includes a gathering chain for conveying printed products and having a variable chain pitch. A stapling device staples the printed products that are conveyed on the gathering chain. A drive device includes a first gear for driving the stapling device, a second gear for driving the gathering chain and a change-over device connected to the first and second gears and having at least two fixed turns ratios.

Abstract: A stapling arrangement of a stapling and gathering machine includes a stapling carriage which is seated on a machine frame and travels with a gathering chain for stapling printed products carried by the gathering chain. At least one stapling head travels with the stapling carriage and with a bending device. A drive mechanism is provided for the stroke of the stapling carriage and the strokes of a shaping element and a punch of the stapling head. The drive mechanism includes a first drive for the stroke of the stapling carriage, and a second drive for the strokes of the shaping element and the punch, and for a movement of the bending device. The first drive can be exchanged independently of the second drive for adaptation to the pitch of the gathering chain. The stapling arrangement can also be converted quickly and easily to a different chain pitch by a semi-skilled operator.
