Abstract
PURPOSE: To strengthen the adhesion between core wire and coating metal by changing relatively the flow rate of coating metal present around and core wire drawn at a definite speed inside a bearing.
CONSTITUTION: The steel wire 9 to which a front tension is applied is passed through the forming die 12 whose bearing inside face 14 has the recessed portion 15 and A and B portions of which have equal inside diameters, and at the same time the aluminium billet 11 is drawn by extrusion onto the circumference of the steel wire 9 to obtain the aluminium-coated steel wire of a predetermined size. The recessed portion 15 may have a curved surface. In case where the A and B portions of the forming die 12 are different in diameter, the billet 11 at the A portion is strongly contracted to cause the enlargement of size at the recessed portion and further reformed at the B portion to obtain the aluminium-coated steel wire 13 of a predetermined size.
