Abstract

The wire (12) is pulled through a calibration hole, the wire being cooled down as it emerges from the hole. Traction is applied to the wire by enclosing it in a continuous circumferential groove (2) in a revolving drawing wheel (1). The groove occupies at least 360 deg. of arc, may be of a 'V' section which is symmetrical about a radial wheel plane, and may subtend an angle of between 15 and 25 deg. Cooling is effect by a liquid stream (8) which contacts the wire between the calibrating hole and the wheel, and which maintains contact whilst the wire enters the wheel groove. The liquid stream may take the form of a moving column, and wheel to wire contact may be applied over a groove arc of between 180 deg. and 270 deg.
