Abstract
In a method for manufacturing sawtooth card clothings and all-steel card clothings for processing textile fibers in a carding process, a sawtooth wire is produced by generating teeth on a wire blank sequentially behind one another in a longitudinal direction of the wire blank, wherein the teeth extend transversely to the longitudinal direction away from a base area. The sawtooth wire is subjected at least in the area of the teeth to a hardening process under exclusion of oxygen in the area of the sawtooth wire. A device for performing the method has a heating chamber having an inlet opening and an outlet opening for the sawtooth wire passing through the heating chamber. An arrangement for generating an inert gas atmosphere in the area of the sawtooth wire passing through the heating chamber is provided.
