  • Method and detector for detecting surface roughness or defects on coated wire or cable
    Patent number: 5365222
    Abstract: A method and detector are provided for accurately and continuously detecting surface roughness or oversize defects on coated wire or cable, such as magnet wire. This is achieved by passing the wire or cable through a die having an opening which is larger than the cross-section of the wire or cable by the size of the surface roughness or defect to be detected. This die is pulled on the wire or cable when engaged by the oversize defect to a spot or position where a sensor is provided to sense the presence of the die and thus of the defect and then produce a suitable alarm.
