Abstract (en)

[origin: EP1393828A2] The wire manufacturing method involves reducing the cross-section of a round wire (4) in one or more stages. The metal wire is shaped to form a flat wire (5) in a laterally open gauge at least during the final stage. The wire is re-shaped into a flat wire without a significant decreases in its cross-section. The metal wire is formed into a flat wire with a maximum ratio of thickness to width of a 1 : 5. AN Independent claim is also included for the following: (a) an arrangement for implementing the inventive method.
