Abstract
Apparatus for heat treating a continuously moving metal wire (19) has at least two drum-like rotational body systems (5a, 5b) which are arranged in the heat-treatment area and around which the wire winds with several turns, and which, to avoid the relative movement between the wire and the surface of the rotational bodies as a result of a length change in the wire during the heat treatment, are each constructed of several disc-shaped rotational bodies (5) which are arranged in sequence, are termed below in short as "discs" and have at their periphery self-contained wire-guiding grooves (6), with all discs of one disc row (5a) being faced by allocated discs of another disc row (5b) with axially offset wire-guide grooves (6). The first disc (5A) of one of the disc rows (5a) is connected non-rotationally to a drive shaft (3), whereas the remaining discs of this disc row (5a) and the discs of the other disc row (5b) or disc rows, possibly with the exception of a likewise driven disc, are rotatably mounted on shafts or axles (4).
