<p>An apparatus for placing current on a moving electrode wire (20) travelling between two points. An electrically conductive member (14) having a circular outer surface and a longitudinal axis is provided at an angle from a straight line between two points and with its circular outer surface in contact with the moving wire (20). The moving wire (20) contacts the circular outer surface along a curvilinear path. The conductive member (14) is received within a bore of a holder body (32). The holder body also includes a wire hole (40) which intersects the bore and communicates therewith through an elongate passage. The moving electrode wire (20) is received through the wire hole and slides over the conductive member surface visible from the wire hole (40). The contact surface is curvilinear shaped. The conductive member (14) may be turned about its longitudinal axis to expose unworn contact surfaces.</p> |
