  • Wirelaying tool
    Patent number: 7069637
    Abstract: A wirelaying apparatus and method using a tool (30) having a cutter/cutting tip (31) operatively opening a cut in the interior bore surface (11) of a cylindrical pipe fitting (10), laying wire (12) into the cut and closing the cut using a flange closer (33). The wire (12) is delivered into the cut via an aperture (32) through the cutting tip (31). Delivery of the wire (12) into the cut is thereby improved, overcoming the problem of wire running free within the fitting. In a second embodiment (see FIG. 12) the cutter (31) is rotatably mounted allowing a double helical coil to be formed without removing the cutter from the bore surface.
