Abstract: The invention relates to an optical measurement probe for process monitoring, having a distal end, arranged in the region of a process apparatus, with a light entrance opening, and a proximal end coupled to a spectrometer, wherein a shaft comprising a light-guiding connection between the distal and proximal ends of the measurement probe is arranged between the two ends. The measurement probe is characterized in that the measurement probe has, in its distal region relative to the shaft and/or the proximal end, a reduced external diameter (FIG. 1).

Abstract: The tension of a web in a multi-web system is regulated. At least two webs initially run through a first processing step independently of each other and are subsequently combined with each other to form one resultant web strand. The web tensions of these two initially independent webs are adjusted to each other through a first regulation process. Each of these webs has its web tension regulated on the separate web path by a dedicated second regulation process which is different from the first regulation process.

Abstract: A cylinder of a printing unit of a web-fed printing press includes a cylinder channel which receives plate ends and includes plate end retaining devices. A remotely controllable actuating device or an actuator is located in the channel. The actuating device, or actuator is preferably a piezoelectric system or is in the form of a magnetostrictive system. This actuator is usable, preferably during continuous printing, to shift a plate end retaining device inside the channel in an axial direction of the cylinder to achieve an improved register precision and lateral register precision. The device makes it possible to counteract the influence of a transverse strain imposed by the material to be printed and acting transverse to its direction of conveyance, such a transverse strain having an effect on a common printed image that is printed at different positions of the printing unit.

Abstract: Tension in a web of material that is passing through a web treatment machine, such as a web-fed rotary printing press, is controlled. The desired value for the web tension is modified to counteract defects that may influence web tension during production operation of the web treatment machine. The modification of the web tension is done in advance of, or concurrently with the arrival of the defect that influences the web tension.
