PROBLEM TO BE SOLVED: To obtain a variable neutral axis wire core using a relatively low temperature thread and a relatively high temperature thread by providing a strip of an extrusion molded strip having an elastomeric cover with a selectively positioned high temperature thread extending longitudinally in the interior to thereby select the neutral bending axis of the strip. SOLUTION: An extrusion molded strip 10 has a U-shaped cross section and has a pair of leg portions 12, 14 connected by a web 16. The extrusion molded strip 10 has a U-shaped wire core 18 having an extrusion molded elastomeric cover 20 therearound. A high temperature thread 28 is extended longitudinally in the elastomeric cover and glued with the elastomeric cover 20. An adhesive is applied to prompt the adhesion between the high temperature thread and the elastic material. The high temperature thread 28 is selectively located with respect to the wire core to provide a desired neutral bending axis of a finished product. The high temperature thread 28 is generally located in the intermediate portion of the leg 14. The high temperature thread 28 can be located along the web in addition to the leg 12. |
