Abstract:
1. A method of determining the core diameter of a wire having a wire core surrounded by an insulating sheath, comprising the steps of: providing a signal applicator having a wire gathering device and a piercing pin movable relative to the wire gathering device; moving the wire gathering device to grasp the wire; moving a piercing pin relative to the wire processing device to pierce the insulating sheath and contact the wire core; applying a sensing signal to the wire core through the piercing pin; moving a pair of electrically grounded wire processing blades into contact with the insulating sheath of the wire; moving the pair of wire processing blades toward the wire core; monitoring for a change in the sensing signal as the wire processing blades move toward the wire core caused by contact between the wire core and the wire processing blades; determining the position of the wire processing blades upon the change in the sensing signal; and determining the diameter of the wire core based upon the determined position of the wire processing blades.
