Method and apparatus for applying uniaxial compression stresses to a moving wire

An apparatus for moving a wire along its own axis comprising in combination:

• a wheel mounted for rotation about an axle, said wheel being a combination of several discs having beveled outer edges, said discs when mounted face to face on said axle define a drive wheel with a least two continuous generally “V” shaped grooves in a peripheral surface of said wheel;
• a plurality of pressure rollers juxtaposed to said peripheral surface of said wheel, each of said pressure rollers mounted for rotation about an axis parallel to said axle of said wheel, each of said pressure rollers positioned to co-act with said wheel and adapted to exert a gradual increase of axial compression stress on a wire disposed in a groove in said wheel, said pressure rollers and said wheel co-acting to move said wire in the direction of rotation of said wheel, and;
• a plurality of guide rollers juxtaposed to said peripheral surface of said wheel said guide rollers disposed tandemly immediately after said pressure rollers in a direction of rotation of said wheel, said guide rollers disposed along an arc having a radius longer than a radius of said wheel, said arc being tangent to said peripheral surface of said wheel where a first of said rollers is positioned, whereby said guide rollers position said wire for entry into a wire processing device.
