Abstract: In a device for the transport of sheets in a sheet-processing machine, preferably a printing press, provision is made to transport the sheets on chain-guided gripper bars. The gripper bars are fixed respectively to two chain links arranged indirectly beside each other. The forces acting on the gripper bars are more evenly distributed.

Abstract: A method of depositing sheets coming out of a sheet-processing machine includes decelerating the sheets and depositing the sheets of a main pile. Certain sheets are decelerated and fed to a second sheet pile. The system includes a device for decelerating the sheets arriving from the sheet-processing machine and for depositing the sheets on a main pile. A chain gripper system is configured to hold and decelerate a trailing edge of the sheets. The chain gripper system includes an adjustable gripper opening cam.

Abstract: An apparatus for forming stacks in sheet-processing machines, in particular printing machines, includes side stops moving back and forth. The stops are divided into upper and lower parts. The lower part can be displaced vertically or in slotted guides and can interact with a switch in order to switch off a stack lift drive.

Abstract: An apparatus for ejecting sheets from a sheet transport path onto an auxiliary stack disposed upstream of a main stack, includes a planar sheet guide surface having a sheet ejection opening formed therein. The sheet ejection opening is closed by a sheet separating element and a flap, in a closed state. The separating element and the flap also serve as guide elements during the ejection of sheets.

Abstract: A sheet brake for a press contains braking elements diverging in the sheet running direction in order to tauten the printing material sheets transversely. The braking elements are driven so as to circulate at a nonuniform speed. The nonuniform speed of the diverging braking elements results in more effective transverse tautening of the printing material sheets.

Abstract: A belt conveyor of a printing-material sheet processing machine includes a belt for transporting the printing-material sheets, the belt having openings, and a roller, which has pins for engaging in the openings. At least one ring is rotatably mounted on the roller, relative to the pins, the belt lying on the ring. This belt conveyor is suited for conveying a printing-material sheet, wherein the belt is driven by the roller virtually exclusively via a form lock between the pins and the openings and virtually without a friction lock between the inner surface of the belt and the peripheral surface of the roller. The belt conveyor may be, for example, a sheet brake of a delivery of a printing press.

Abstract: A delivery for a machine for processing flat printing materials includes sheet brakes for accepting sheets fed in a processing direction at an acceptance level and for releasing the sheets at a surrender level. The sheet brakes are adjustably disposed for varying the acceptance level and the surrender level. A machine is provided for processing flat printing materials, having the delivery.

Abstract: A method for transversely tautening a print-carrier sheet includes applying a twisting movement to a belt and transversely tautening the print-carrier sheet with the belt having the twisting movement. A device for performing the method and a print-carrier sheet processing machine, such as a sheet-fed printing press, including the device, are also provided.

Abstract: Apparatus for transferring a rod-like filler of fibrous material of the tobacco processing industry from the underside of a foraminous suction belt conveyor to the concave upper side of a running web of cigarette paper or other suitable wrapping material upstream of the station where the web is draped around the filler and downstream of the station where the fibrous material is showered against the foraminous belt conveyor has a so-called garniture belt conveyor which advances the web along a horizontal path, and a guide which compels an upstream portion of the foraminous belt conveyor to advance above and in at least substantial parallelism with the garniture belt conveyor. The guide causes a downstream portion of the foraminous belt conveyor to slope downwardly toward the garniture belt conveyor.
