A device detects at least one position of at least a part of a printing material while the printing material is transported in a printing machine. The device includes an optical sensor for establishing a distance between a printing machine component and the printing material. The distance established by the optical sensor is temperature-compensated by a computer.

A sheet-fed printing press includes a printing cylinder and a high-precision sensor system for monitoring a sheet run in the area of the printing cylinder. At least one gage, which is mounted on the printing cylinder, can be detected by the sensor system. It is particularly advantageous if the sensor system is configured to be self-calibrating. A method for calibrating a sensor system and a method for aligning a sensor system are also provided.

An apparatus for turning a sheet during transport through a printing press provides better printed results as a result of improved sheet guidance. A transfer drum has gripper systems disposed in channels for holding the sheet at the leading and trailing sheet edge, and guide elements covering the channels.

A device for transporting sheets in recto or verso printing operation has tongs grippers each with upper and lower grippers. The upper gripper, or rigid gripper, that forms the gripper pad can be locked directly or indirectly in recto printing operation.

A method of varying a drum profile of a vario drum for transporting printing material sheets, in which shell segments of the vario drum are pivoted inward and outward. Sheet supporting elements assigned to the shell segments are reversibly deformed by pivoting the shell segments. A vario drum suitable for implementing the method and a machine containing the vario drum for processing printing material sheets contain the shell segments and the associated sheet supporting elements.

Method of varying a drum profile of a vario drum and vario drum for implementing the method

A machine for processing printing material sheets, in particular a sheet-fed printing press, has a sheet transport drum for transporting the printing material sheets and at least one sheet supporting element. The sheet supporting element, which is formed with a sheet supporting surface, is compatible with the sheet transport drum, for supporting the printing material sheets in a first operating mode. When the machine is operated in the first operating mode the sheet supporting element is held attached to the sheet transport drum, and when the machine is operated in a second operating mode the sheet supporting element is stored in the machine detached from the sheet transport drum. A corresponding printing material processing machine is suitable for carrying out the novel method.
