Zusammenfassung:	PURPOSE:To provide a method and a device for rolling and drawing a wire which prevents a roll under rolling and drawing of the wire from being broken to prolong the service life of the roll, stabilizes the shape of the wire rod and is easy to control the diameter of the wire rod. CONSTITUTION:Plural rolling units 9 having a three-rolls assembly 7 of an undriven or motor-driven triangular caliber and a three-rolls assembly 8 of a motor driven round caliber are arranged in series so that a wire is rolled from three directions, a reverse tension is applied by dancer rolls 11 for applying a reverse tension to the wire entering each rolling unit and the wire ejected from each of rolling units is drawn by capstans 10 arranged on the downstream side of the rolling units.
