Abstract: A printing machine (10) comprises a doctor blade (14), a drive system (20) for urging the doctor blade (14) against a printing cylinder (16) of the printing machine (10), a sensor (32) adapted for sensing a force with which the doctor blade (14) is urged against the printing cylinder (16), and a mechanical locking element (34) adapted for locking the drive system (20) in its operating position. Further, a method of operating a printing machine (10) is presented.

Abstract: A contactlessly measuring system having a contactlessly measuring device, with a light transmitter portion and a light receiver portion, for determining the position of a tool or for determining the longest cutting edge of a rotating tool in a tool machine. A light barrier system is formed by the light transmitter portion and the light receiver portion, each being associated with a leg of an essentially U-shaped support structure of the measuring device. A fluid blowing device, associated with the measuring device, is provided for cleaning a tool to be measured, and/or a sealing air feed is provided in the area of a measuring beam of the measuring device designed as a light barrier measuring system, and/or a protective/closing device is provided at the light transmitter portion and/or the light receiver portion of the measuring device designed as a light barrier measuring system.

Abstract: A process is disclosed for operating an industrial plant by means of a guidance system that controls processes in the industrial plant, in which process operation-relevant data such as states, malfunctions and/or degradation of devices of the industrial plant are acquired by an operator; the operation-relevant data are acquired in an operation monitoring system and stored in electronic, preferably standardized form, and operation-relevant data on events which can affect process control, such as malfunctions of devices, are electronically transmitted to the guidance system.
