A sheet processing machine for the processing of sheets of paper, cardboard, and the like, includes at least one processing station, one delivery unit, one sheet transport system including circulating gripper carts, which are driven by individually actuated linear drives, a machine control system and braking devices located in the entry zone of processing stations. The back edge of the respective sheet at its stop position in the delivery unit and/or the at least one processing station lies directly above the back edge of the delivery stack and/or the back edge of a tool or die of the processing station.

Back-edge braking system

A method for correcting the lateral position of a printing material, includes gripping the printing material with a transport unit, rotating the transport unit in a lateral position correction angular range for correcting the lateral position of the printing material, and rotating the transport unit out of the lateral position correction angular range while retaining the correction of the lateral position of the printing material. An apparatus for correcting the lateral position of a printing material, a printing material conveying system and a machine for processing printing material, are also provided.

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.

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.

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.

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.

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.

A device for registering the position of a rotor part in a transport system also having a static part in addition to the rotor part includes a dimensional standard forming part of the rotor part, and a plurality of transmitters provided on the static part; and a printing unit and a printing machine including the position registering device.

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

An apparatus for transporting a sheet material through a sheet-processing machine is described. The transport system for the sheet material has a drive that is driven independently of the cylinders on the stations processing the sheet material in the sheet-processing machine. The transport system provides at least synchronization of a transport device conveying the sheet material and of the cylinders.
