Abstract
1363199 Rolling wire MORGARDSHAMMAR AB 11 Sept 1972 [10 Sept 1971] 42042/72 Heading B3M In a method of cold drawing a metal wire rod through a pair of oval groove rolls and then through a pair of round groove rolls 3, 4, the pair of round groove rolls 3, 4 are axially prestressed F 1 , F 2 in opposite axial directions and the oval rod 5<SP>1</SP> is led into the round groove rolls 3, 4 such that its major axis is inclined by an angle α of up to 10 degrees relative to the plane which is perpendicular to the roll axes. As a result, the rolls 3, 4 are moved back to a centred position against the prestressing, which is achieved by springs, and the oval rod 5<SP>1</SP> is rotated back to an upright position thereby avoiding the formation of a rod of non-circular section. The rod is inclined by arranging the pair of round or oval groove rolls at an angle of 80-88 degrees relative to the other (Fig. 6, not shown) or maintaining the perpendicular arrangement of the oval and round roll pairs and designing the oval groove so that its axis forms an angle of 2-10 degrees with the plane of division of the rolls.
