    摘要: An apparatus for guiding and transferring a sheet in a printing machine from a first cylinder to a gripper of a second cylinder in which the apparatus has a guide device for a holding element, which is held outside the first and second cylinder. In this way, the design of the guide apparatus can be independent of the first and second cylinders. In addition, a longer time period is available for gripping, tensioning and transferring the sheet. The apparatus can be used both in a recto printing machine and in a turner device in recto and verso printing.

    摘要: In an apparatus for adapting the pressing force of a control roller on a control can in a sheet-processing machine by a torsion spring, the apparatus either changes the effective spring length or the spring stiffness as a function of the rotational speed of the sheet-processing machine. The spring can be a torsion spring rod with an actuator setting the spring force by changing the prestress. A stiffening element can be connected to the torsion spring rod and set the spring force by changing the spring stiffness of the torsion spring rod.

    摘要: A reversing or turning assembly of a sheet-processing machine includes an impression cylinder having a circumferential surface for transporting sheets thereon for printing the sheets in a printing nip associated with the impression cylinder. Gripper devices are provided for gripping the printed sheets at a respective trailing edge thereof and for lifting the gripped sheets off the impression cylinder for reversing the gripped sheets. The circumferential surface of the impression cylinder is formed with recesses in a region thereof occupied by the trailing edge of the sheets, for permitting the gripper devices to penetrate or dip into the recesses to grip the sheet trailing edge. The recesses have a position being variable in circumferential direction of the circumferential surface of the impression cylinder for adapting to different sheet formats.
