Method for regulating a roll changer and roll changer

摘要

The method involves applying a current precontrol value (24) as precontrol value, with which the initial value (22) of the speed controller (16) is charged for determining the input value (23) for the current controller (15) corresponding to the preset density of the print substrate roll (10). The precontrol value adapted corresponding to the current controller is matched with an actual current value (25).
