METHOD AND DEVICE FOR MANUFACTURING SAWTOOTH CARD CLOTHING AND ALL-STEEL CARD CLOTHING AS WELL AS SAWTOOTH WIRE

摘要

A method for manufacturing sawtooth and all-steel card clothing so as to process textile fibers by a method capable of manufacturing card clothing promptly and reliably without damaging quality of the card clothing is provided. As a method for manufacturing all-steel card clothing and sawtooth card clothing for processing textile fibers in a carding process, the method comprises: producing a sawtooth wire by generating teeth portions on a wire blank sequentially behind one another in a longitudinal direction of the wire blank, wherein each of the teeth portions transversely extend to the longitudinal direction by departing from a base area; performing a hardening process of the sawtooth wire at least in the area of the teeth portions in the state that oxygen is excluded in the area of the sawtooth wire; and preferably passing the sawtooth wire through a heating chamber. As device for implementing the method, the device comprises: a heating chamber having an exit opening and an entrance opening for passing a sawtooth wire through the heating chamber; and an installation for generating an inert gas atmosphere in the area of the sawtooth wire passing through the heating chamber.
