1. A wire-twisting machine for fabricating straight and contrahelically wound sections comprising:

  • means for securing a first wire between first and second fixed end means;

    first and second coaxially spaced pulley wheels located inwardly of the fixed points and having central openings therein through which the first wire passes;

    stationary guide means located between the second pulley wheel and the second fixed end means, the guide means having a coaxially located central opening for allowing the first wire to pass therethrough;

    a second wire secured to a radially outward point on the first pulley wheel and positioned in parallel spaced relation to the first wire;

    radially outward openings formed in the second pulley wheel and the guide means for passing the second wire for securement to a point on the second fixed end means; and

    means for rotating the pulley wheels in synchronous rotation while undergoing limited translation therebetween wherein the second wire is helically wound around the first wire between the second pulley wheel and the guide means while the first and second wires remain parallel and unwound outwardly of the second pulley wheel and the guide means.
