Abstract: A wirelaying apparatus includes a tool arm with a tool head which carries a wirelaying tool. The tool has a cutting tip through which a wire is laid into a working surface of a workpiece. The workpiece is retained in a retainer and is moved relative to the wirelaying tool. In use, the cutting tip follows along an arcuate path while laying the wire into the working surface of the workpiece. Thus, more complex wirelaying configurations are achieved, such as a bi-helical wirelaying pattern in a generally cylindrical pipe fitting or a bi-spiral wirelaying pattern in a semi-cylindrical saddle coupler pipe fitting.

Abstract: A wirelaying apparatus (2) includes a tool arm (21) with a tool head (22) which carries a wirelaying tool (30). The tool (30) has a cutting tip (31) through which a wire (12) is laid into a working surface (11) of a workpiece (10). The workpiece (10) is retained in a retainer (40) and is moved relative to the wirelaying tool (30). In use, the cutting tip (31) follows along an arcuate path while laying the (10) wire into the working surface (11) of the workpiece (10). Thus, more complex wirelaying configurations are achieved, such as a bi-helical wirelaying pattern in a generally cylindrical pipe fitting or a bi-spiral wirelaying pattern in a semi-cylindrical saddle coupler pipe fitting.

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.
