ABSTRACT:
Method and apparatus for twisting conductors into a twisted pair in which the conductos are passed from two axially aligned reels and axially out of a cylinder. The conductors pass through one twist position axially at one end of the cylinder, extend around the cylinder and along the cylinder to the other end to a second twist position. The conductors are drawn along their paths during rotation of a flyer radially outside the cylinder. Speed of rotation of the conductors leaving the reels forces the conductors against the inner surface of the cylinder against which the conductors slide as they move towards the first twist position. The flyer means is provided, preferably, upon the outer surface of the cylinder.
