Abstract (en)
[origin: US4549420A] The wire-cross-section is first reduced down to an intermediate cross-section by subjecting the wire to a cold-rolling in a rolling-section with a plurality of stands which is part of a manufacturing unit. The cross-section is continuously further reduced down to the required cross-section in a wire-drawing section forming also part of the manufacturing unit. The first step in the reducing in the wire-drawing section is performed in a roller die, the other steps being performed in normal dies. The lubricating oil circuit for the roller die is completely isolated from the lubricating oil circuit for the other dies. After wire-drawing the wire is coiled on a coiling-machine.
