Abstract
A method for setting a gap dimension of a gap between a die cutting cylinder and a counter pressure cylinder of a rotary die cutting device includes providing a control system including a controller, at least one sensor, and an adjusting device actuated by the control system. The method further includes actuating the adjusting device in response to the at least one sensor sensing a deviation of a web being processed from a desired state which includes a set of one or more detectable parameters with quantifiable and measurable variables, thereby setting the gap dimension between the rotary die cutting device and the counter pressure cylinder, in which actuating the adjusting device is achieved as a result of the control system operating in a closed feedback loop. The method further includes sensing by the at least one sensor occurring with or without disruption of operation of the rotary die cutting device.
