Abstract (en)

[origin: EP0346534A2] Single and multi-wire drawing apparatus and method are described. A first wire drawing section (12) includes two pairs of cone drawing blocks (20, 24; 36, 40) and two tandem drawing blocks (48, 56). A second wire drawing section includes a number of tandem drawing blocks (58-64), four in the described embodiment, and a final capstan drawing block (66). The final tandem drawing block (56) of the first wire drawing section (12) is arranged on the second wire drawing section (14). All of the drawing blocks of the first wire drawing section (12) are driven by a single drive (78), while the tandem and the final capstan drawing blocks on the second wire drawing section (14) are actuated by a second drive (92). The dies (68-76) associated with each tandem drawing block (58-64) of the second section (14) are movable so that a number of different wire sizes can be produced by appropriately moving the dies (68-76) and adjusting the speed of the first drive (78) to provide a desired wire speed entering into the second wire drawing section (14).
