Scoring device and methods for setting axial position and gap dimension

A method for operating a rotary scoring device, comprising:

• feeding a material web to be treated into a feed of the rotary scoring device;
• sending data associated with at least one characteristic property of the material web, measured by at least one sensor, to a control unit;
• operating an adjusting device to adjust an axial position of one or more score blades;
• operating a motor to adjust a gap dimension between the one or more score blades and an anvil shaft, the motor including an encoder to send a feedback signal, to determine at least one of speed, RPM, count, distance or direction;
• and
• setting the axial position and the gap dimension between the one or more score blades and the anvil shaft to a desired location to treat the material web.

A method for setting a gap of a rotary die cutting system, comprising:

• providing a control system including a controller, at least one sensor, a first adjusting device, and a second adjusting device, each actuated by the control system;
• actuating the first adjusting device in response to the at least one sensor sensing a deviation from a desired state, thereby setting a gap dimension between a rotary die cutting device and a counter pressure cylinder of a rotary die cutting device;
• and
• actuating the second adjusting device in response to the at least one sensor sensing a deviation from a desired state, thereby setting an axial position and a gap dimension between one or more score blades and an anvil shaft of a rotary scoring device, wherein the rotary scoring device positioned in series with respect to the rotary die cutting device, wherein actuating the second adjusting device is achieved as a result of the control system operating in a closed feedback loop, and
• wherein sensing by the at least one sensor occurring with or without disruption of operation of the rotary die cutting system.

A rotary scoring device, comprising:

• a frame including at least one blade holder, containing a score blade therein, and an anvil shaft, the at least one blade holder is separated from the anvil shaft by a gap;
• and
• a control system including a controller, at least one sensor, and a first adjusting device and a second adjusting device actuated by the control system,
• wherein the first adjusting device is operably connected to the at least one blade holder to adjust an axial position, and
• wherein the second adjusting device is operably connected to the at least one blade holder to adjust a gap dimension between the score blade and the anvil shaft.
