Wire straightener

Abstract

Abstract A wire straightener comprising a planar plate, means for drawing wire having a cast along and in contact with the planar plate and in a plane parallel to the plane of the planar plate and means engaging the wire in staggered positions at opposite sides as it is drawn along and in contact with the planar plate snugging the wire against the planar plate so that axial rotation of the wire is minimized and the wire is delivered from the straightener substantially straight and free from cast. Means may be provided for controlling orientation of the wire as it moves into contact with the planar plate so that its cast lies in said plane parallel to the plane of the planar plate. Wire may be fed from a coil whose axis is substantially normal to the plane of the planar plate whereby to control the orientation of the wire as it moves from the coil into contact with the planar plate so that its cast derived from coiling lies in said plane parallel to the plane of the planar plate. A turntable may carry the coil of wire, turning to pay out wire from the coil as the wire moves from the coil into contact with the planar plate. The wireengaging means may be rotatable elements whose axes intersect the plane of the planar plate, such elements increasing in diameter from the planar plate outwardly, as conical rollers. Cylindrical rollers whose axes are inclined to the planar plate may be employed. Elements of the surfaces of the conical or cylindrical rollers make an angle of between about 45* and about 85* with the planar plate. Means may be provided for varying the distance between the rotatable elements at opposite sides of the wire to accommodate the straightener to wires of different casts or stiffness.
