Abstract: A process provides for the safe operation of a printing machine. The printing machine has a first cylinder driven by a first motor, and a second cylinder driven by a second motor. The first cylinder accepts sheets of paper from the second cylinder or delivers them to the second cylinder by a gripper system. In the case of a deviation in the synchronized running between the cylinders, the gripper system is retracted at least in part far enough into the first cylinder that the possibility of a collision of the gripper system with the second cylinder is eliminated.

Abstract: An interface transfers signals from a hand-operated signal generator (1) to a data processing device (2). The hand-operated signal generator (1) is capable of generating at least two types of signals for moving an image in at least two different ways on a display (3) associated with the data processing device (2). Such an image is a 3D image, for example. Each type of signal corresponds to at least one specific mode of operation of the signal generator (1) associated with said type of signal. On the basis of signals generated by the hand-operated signal generator (1), a value determining circuit (23, . . . , 28, 35, 36) in the interface determines a value for each type of signal. On the basis of the values as determined for each type of signal, a relevance determining circuit (39) in the interface determines which of the values determined before is more relevant than the other.

Abstract: A sheet transport system for a rotary press having rails (6a, 6b) configured on both sides of a sheet transport path, driven grippers (20a, 20b) gripping a sheet (2) to be transported near its front end, viewed in the feed direction, at its side edges and pulling it through the rotary press.

Abstract: A transport system is configured for a machine that processes printing material. The transport system has a guide device with one or more diverters and one or more runners that travel along the guide device. An electric linear drive of the transport system has a primary part formed with winding cores and a secondary part formed by the runner. In the region of the diverter, at least one of the cores has a lower height than the cores outside the region of the diverter. This forms a cutout or depression for at least one guide segment of the guide device.

Abstract: A gripper device in a sheet-processing machine includes a gripper, a gripper pad associated with the gripper and a first drive for moving the gripper out of an opened position thereof into a closed position thereof. The gripper is cooperatively engageable with the gripper pad for producing a clamping force for holding sheets being processed. A second drive is separately operable from the first drive during a production printing operation of the sheet-processing machine. The first and second drives are operable for positioning the gripper and/or the gripper pad so that clamping faces of one of the gripper and/or the gripper pad are movable by the second drive perpendicularly to clamping faces of the other of the gripper and/or the gripper pad.

Abstract: An apparatus for transporting a printing material sheet includes a holding crossmember for holding the printing material sheet and a traveling-wave motor for driving the holding crossmember. The traveling-wave motor has a first traveler and a second traveler for mounting the holding crossmember. The holding crossmember is mounted through a spring suspension. The spring suspension can be, for example, a flexible joint in the form of a flexible bellows.

Abstract: In a method and an apparatus for feeding sheets to a sheet-processing machine, the leading edge of the sheet is smoothed before the grippers are closed by further transport into the sheet-processing machine. A curvature or bend in the sheet transport direction is imparted to the sheet. The feed table has, in its feeder region, a curvature in the sheet transport direction, against which curvature the sheet leading edge is laid with the aid of pneumatic or mechanical devices.

Abstract: A conveyor system (10) for a sheet of printing material (12) in a printing material processing machine (14), including a running member (16) which can be moved through the machine (14) along a transport path (18) using a drive (22), and including a number of encoders (24) which are arranged along the transport path (18) and used to sense the position of the running member (16), the conveyor system having the feature that the encoders (24) are connected to an evaluation unit (26) for progressive sampling of the encoder signals; it being possible for an active encoder (28) and a passive encoder (30) of the number of encoders (24) to be specified in the evaluation unit (26) so that a drive signal can be generated in a signal processor unit (32) on the basis of a change in amplitude of the signal of the active encoder (28) and a change in amplitude of the signal of the passive encoder (30).
