<p>A cable following apparatus having a rotating annulus at the front portion of the main body where the opening of the body passing over the cable first comes in contact with the concentric neutral wires. The annulus, by rotating in the direction of the neutral wrapping wires, has the effect of wrapping down any wires that are broken. Further, a helical groove is cut in the front surface of the rotating annulus. The opening to this rotating helical groove extends beyond a static cutter plate which comprises a major portion of the front surface of the main body. The groove angles back along one side of the annulus at an angle which is close to but less than the perpendicular to the direction of travel of the main body. As a result, the terminal end portion of the helical groove is rotating in a plane slightly behind the static cutting surface. Wires that are broken and pulled away from the cable are picked up and carried through the groove to a position where they are held against the surface of the static cutter and cut off by the force of the side of the helical groove pressing the wire against the static cutter surface face.</p> |
