Filed: 1996-10-22
Abstract: PROBLEM TO BE SOLVED: To increase the wire gripping force of a spiral rod at both the end parts of the rod by a method wherein the rigidity of at least the one-pitch length parts of both the ends of the spiral rod is increased. SOLUTION: A resin layer 3 is formed around a reinforcing core 2 consisting of galvanized steel wires, etc., to obtain a wire main part and the wire main part is formed into a spiral with a length about 250cm to obtain a spiral rod 1. The resin layer 3 has a triangular cross-section and its lower side which is brought into contact with a wire is made of conductive resin 3a and its upper side is made of insulating resin 3b. The parts of both the ends which are a little longer than one pitch length P are covered with large rigidity material 5 such as aluminum, aluminum alloy, steel alloy, stainless steel, iron, etc. The length of the high regidity part must be at least one pitch length P. If it is less than one pitch length P, the high regidity end part of the spiral rod does not make one full turn around the wire and hence the gripping force is not enough. As a result, the wire gripping force of the spiral rod at both the end parts can be increased.
