ABSTRACT:
The invention relates to the rolling and drawing of metals. The microwire manufacturing method according to the invention is characterized in that a microwire blank (1) is rolled during the drawing process in opposite directions relative to the drawing axis (B--B). The blank (1) is rolled over the same distance equal to at least one half of its circumference. The method is carried out with the aid of a device comprising a body (3), a die (4) and a mechanism for drawing wire through the die (4). The die (4) is composed of two parts (5 and 6) which interact with the blank (1) as the latter is drawn between them. Each of the die parts (5 and 6) has a working surface (8). According to the invention, the parts (5 and 6) of the die (4) are secured in the body (3) so that they can be set in synchronized reciprocating motion in parallel planes. The working surfaces (8) of both parts ( 5 and 6) of the die (4) are flat and parallel with each other and the drawing axis (B--B).
