An apparatus consistently imparts a desired cast characteristic and a desired helix characteristic to drawn wire. A set of interchangeable rollers imparts the cast characteristic to the wire in a first plane, and a helix control assembly imparts helix control by shifting the wire leaving the rollers into a second plane. The helix control assembly includes a rotatable sheave and a movable block. The plane in which the sheave resides and to which the wire is shifted is manually controlled by a handwheel. The rollers and the helix control assembly are supported by a common support. The rollers may be mounted in respective universal base plates, a selected one of which is received in an opening in the frame, thereby greatly reducing tooling and maintenance costs and providing improved flexibility in production. Moreover, the rollers include movable rollers interspersed with fixed rollers, wherein the movable rollers may be individually adjusted on either side of the center line of the fixed rollers.

An apparatus for controlling the helix characteristic of wire drawn from a wire source by means for pulling the wire, said apparatus comprising: means, located between the wire source and the means for pulling the wire, for guiding the pulled wire along a path to alternately bend the wire in a first plane, means, located between said guide means and the means for pulling the wire, for selectively exerting forces on the pulled wire, said forces being exerted on the pulled wire in a direction outside the first plane causing the wire to run on an angle, said force exerting means guiding the wire in a second plane which is parallel to said first plane.
