Patent ID: 8051681

Claim:
A scoring, device, comprising: an extendable score wheel; a first linear motor/actuator arranged to move said score wheel in an X-direction along a side of a bowed sheet of material; a ranging sensor that obtains positional information about a location of the side of the sheet of material; a second linear motor/actuator arranged to move said score wheel in a Y-direction towards the side of the sheet of material; a controller that receives the positional information from the ranging sensor; a first actuator configured to extend said score wheel relative to the second linear motor/actuator further in the Y-direction towards the side of the sheet of material, and wherein said controller is configured to operate the second linear motor/actuator to move the first actuator and the score wheel in the Y-direction and use said positional information to operate said first actuator to move the score wheel relative to the second linear motor/actuator further in the Y-direction such that said score wheel applies a substantially constant scoring force to the side of the sheet of material.
