Method for adjusting the processing position of at least one processing device not clamping a product web to be processed

摘要

A method for adjusting the processing position of at least one processing device not clamping a product web to be processed within the context of longitudinal register control in a processing machine includes arranging the at least one processing device in a web section which is delimited by two clamping points. The method further includes applying an actuating variable for adjusting the processing position to the at least one processing device within the context of feedforward control, and calculating the actuating variable for adjusting the processing position on the basis of a register deviation expected from a control action of a tensile force control device for controlling the tensile force in the web section.

1. A method for adjusting the processing position of at least one processing device not clamping a product web to be processed within the context of longitudinal register control in a processing machine, comprising:
arranging the at least one processing device in a web section which is delimited by two clamping points; calculating an expected register deviation that will result from a control action of a tensile force control device for controlling the tensile force in the web section; calculating an actuating variable for adjusting the processing position on the basis of the expected register deviation resulting from a control action of a tensile force control device for controlling the tensile force in the web section; and applying the actuating variable as a feedforward control to the at least one processing device.
