Operating a continuous sheet-processing machine, e.g. a printing machine, using process variables determined by measuring changes in influencing variables caused by modulating drive speeds for processing elements

摘要

A method for operating a continuous sheet-processing machine with an array of process elements and drive units (11) for the transport and/or processing of continuous sheet material, in which the speeds of at least some of the drives (11) are modulated with a preset modulation frequency and process variables for the machine are determined by measuring changes in the influencing variables for the drives (11) caused by the modulations.
