Abstract
An apparatus and method for moving a wire along its own axis against a high resistance to its motion causing a substantial uniaxial compression stress in the wire without allowing it to buckle. The apparatus consists of a wire gripping and moving drive wheel and guide rollers for transporting the moving wire away from the drive wheel. Wire is pressed into a peripheral groove in a relatively large diameter, rotating drive wheel by a set of small diameter rollers arranged along part of the periphery causing the wire to be gripped by the groove.
