METHOD FOR REGISTER CORRECTION IN A WEB PROCESSING MACHINE HAVING A DELAY SECTION

摘要

A method for register correction in a web processing machine includes leading a product web through at least one delay section and processing the product web by a first processing device. An actuating command is applied to the first processing device to position the product web at an intended position during a web tension change. The actuating command is determined from an actuating command leading to the web tension change and at least one delay term. The at least one delay term delays the action of the actuating command leading to the web tension change on the actuating command for the first processing device by a delay time needed by the product web to pass through the at least one delay section before the first processing device.
