Abstract: A method for producing a connection unit (1) which has a connector with a connector shaft (6) and a disc (3) which is captively arranged on the connector shaft (6). The disc (3) has an annular disc body (23), the inner contour (33) and outer contour (34) of which have been produced by a plastic deformation of the disc body (23). The inner contour (33) is shaped such that the disc body (23) is fixed on the connector shaft (6). At the same time, the originally non-circular outer contour (34) is shaped so as to be at least substantially circular. The deformation process is carried out by introducing radial deformation forces into the outer circumferential surface (27) of the disc body (23).

Abstract: A stack gripper has two pairs of support elements, which are arranged next to one another and are adjustably fastened to a transverse carrier. A drive is provided for an adjustment apparatus, with which the spacing between the two pairs can be changed without the lateral spacing of the support elements of a pair being changed.

Abstract: In a method for the cutting of paper products, the paper products are trimmed at at least one side in a cutting apparatus and are subsequently ground.

Abstract: A rotary cutting knife for the cutting of print shop products is provided with a blade carrier at whose outer periphery blades are arranged such that only one cutting edge of the blades essentially projects over the outer periphery of the blade carrier. The blade carrier has cut-outs between two adjacent blades at its outer periphery.

Abstract: A system for the handling of paper products has a cross-stacker, a pressing module and a dispensing module which are arranged along a straight conveying path. A rotation device which permits a rotation of a stack of paper products by 180° is provided.

Abstract: A cross-stacker for paper products has a pre-collection chamber, at least one rotation device and two ejection devices, with a transport device being provided beneath the pre-collection chamber which transports paper products collected in the pre-collection chamber.

Abstract: A stacking apparatus for paper products comprises a supplier of an overlapping stream of paper products and a plurality of receiver elements to form a layer. A rotation device is arranged beneath the receiver elements, with the orientation of the supplied printed products being rotated through 90° with respect to the orientation of the layer on exiting the further receiver element.

Abstract: An apparatus for parting a shingled flow of two-layer paper products in the vertical direction with a rotatable deflector sheave and a wedged-shape deflector, both pivotally mounted above the shingled flow, wherein the wedged-shaped deflector may be inserted into the shingled flow and retracted at a speed in the conveying direction which exceeds the conveying speed of the shingled flow.
