Image Number 15 for United States Patent #6936124.
A wire joint detecting apparatus is provided for use with a wire connecting apparatus. A detecting apparatus includes a detector disposed for sliding contact with a running wire. The detector is mounted for pivotal movement in response to cross-sectional dimensional changes of the wire. The apparatus also includes a detection switch for detecting pivotal movement of the detector. The pivotal movement of the detector is indicative of a cross-sectional dimensional change of the wire that indicates the presence of a joint.
