Abstract: A wire construction is provided in which five fine filaments of stainless steel wire are helically overwound about a center filament, also formed of stainless steel. The diameter of the central filament is slightly larger than the diameter of the helically wound filaments, which are of uniform diameter. The wire so constructed retains a high degree of elasticity following manufacture, and is especially suitable for application as an orthodontic wire for use in bracework for straightening teeth, especially the teeth of adolescent children. The wire is formed on a multi-bobbin tubular strander, and during manufacture all of the wire strands are maintained under tension, although the center strand is maintained under greater tension than the helically overwound filaments.

Abstract: A cable for the reinforcement of plastic and elastic articles, such as conveyor belts and the like, is provided which includes a plurality of metal strands which are twisted to form a cable and a non-metallic insert which is disposed between the surfaces of the strands which oppose each other so as to prevent the strands from contacting each other, while leaving the surfaces of the strands which define the outside diameter of the cable exposed. A method and device for producing the cable is also provided.

Abstract: A method of making environmentally approved power lines without entrapment of abrasive blasting ingredients. Each strand to form the top layer of the bare standed non specular conductor is made non specular before it is twisted thru the closing block on the cable strander so that the completed conductor becomes non specular. The preferred method of non specular finishing each strand for the top layer is by means of abrasive blasting.
