Abstract
Official abstract text for this publication.
A method for regulating a web tension in a processing machine for processing a product web, in particular a shaftless printing press, includes separating a first product-web section from a second product-web section by a delay section. The web tensions in the first and second product-web sections are influenced by first and second actuators, respectively. To regulate the web tension in the first product-web section, the method further includes defining a regulation output value from which an actuating command for the first actuator is derived. An actuating command for the second actuator is defined from the regulation output value and a delay element to decouple the web tension in the second product-web section from the regulation of the web tension in the first product-web section. The delay element delays the effect of the regulation output value on the actuating command for the second actuator by a delay time.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for regulating a web tension in a processing machine for processing a product web, comprising: separating a first product-web section from a second product-web section by a delay section, which includes at least one roll, at least 25% of which is wrapped around by the product web: influencing a first web tension in the first product-web section by a first actuator and influencing a second web tension in the second product-web section by a second a…
