Abstract

The wire passes through a die, a device to remove lubricating oil (3) and a seal into a container (5) where it is rolled on a reel. The reducing gas is supplied via a tube and valve (6, 7) and bled off when necessary through another tube and valve (8, 9). A driving motor (14) rotate the reel. The interstices formed between the wire turns on the reel are thus filled with the reducing gas. Subsequent heat treatment of the wire can be carried out in a shorter time than if the wire had been wound in air.
