A method for producing individual material sections, particularly sheets of paper, according to a certain format, from a web-type, for example imprinted object (object web), more particularly a web of paper or material, using a cutting means for cutting off the individual material sections from the object web and then removing said sections from the cutting means, wherein during the course of actuation of the cutting means at least one carrier is engaged with the object web, wherein following the cutting process, the carrier is displaced, together with the object web gripped by said carrier, by means of a controllable linear drive, over a displacement stroke, which is adjusted and/or varied in a controlled manner by the linear drive according to a section format that is predefined for the material section.

Variable folding system comprising linear drives, especially for printing machines

An electrical drive system for angular positioning of one or several rotating and/or tilting machine components and equipment components, particularly of printing machines, including at least one electric motor having a rotor designed for rigid and direct coupling to the component, further including by one or several angle encoders for registering the angular motion of the rotor of the electric motor and/or the component, a signal processing module which receives the actual angle position signals from the angle encoder or encoders and which also receives the setpoint data for comparison with the actual data, and a power amplifier controlled by the signal processor and used for driving the electric motor.

Printing machine with positionable interacting cylinders

Process for the measurement of the absolute position of the movable, cyclic division mark carrier of an incremental position indicator or rotation indicator/resolver within and/or with regard to one of its divisional segments, periodically formed and/or delimited by the division marks on the carrier, with two scanning elements, stationarily arranged and addressing the division marks, which are positioned at such a distance from one another along the length or periphery of the segment that they deliver two sine- and cosine-like measurement signals which are evaluated on the basis of the arctangent function for position determination, by utilizing the values or components of a parameter vector identifying the measurement process, which is continuously redetermined during the measurement operation according to preset optimization criteria, for correction of the evaluation for disturbances and inaccuracies in the position indicator.
