Abstract
A method for measuring and regulating the elongation of a moving material web that includes the steps of measuring the length change or speed change occurring over a drive roller, from which the elongation is calculated and, if it deviates from the desired elongation, the web tension is corrected in order to set the elongation. Such a method is preferably used in a web tension device disposed between a roll exchanger and a printing press. The web tension is preferably adjusted through the use of a dancer roller, whose force exerted on the material web is regulated by a controlled dancer cylinder.
