Abstract
A method of hardening a clothing wire for processing textile fibers and to an apparatus system therefor. The clothing wire has a succession of teeth arranged in its longitudinal direction, and the clothing wire is guided through a heating region in a pass-through direction for contact with at least one open flame. The heating region is followed by a quenching bath having a quenching liquid and by a subsequent tempering apparatus. The clothing wire moving in the pass-through direction is flushed around with a protective medium in a transition region between the region of contact with the open flame and the entry into the quenching liquid.

A method of hardening a clothing wire for processing textile fibres, the clothing wire having a longitudinal direction and a succession of teeth arranged in the longitudinal direction, the method comprising:
- guiding the clothing wire through a heating region in a pass-through direction for contact with at least one open flame;
- following the heating region, guiding the clothing wire through a quenching bath having a quenching liquid;
- subsequent to the quenching bath, guiding the clothing wire through a tempering apparatus;
- and
- flushing the clothing wire moving in the pass-through direction around with a protective medium comprising the quenching liquid in a transition region between a region of contact with the open flame and an entry into the quenching bath, including bringing the quenching liquid, with a flow movement in a flow direction from the quenching bath as far as the heating region, the flow direction being opposite to the pass-through direction of the clothing wire.
An apparatus for hardening a clothing wire for processing textile fibres, the clothing wire having a succession of teeth arranged in a longitudinal direction of the clothing wire, the apparatus comprising:
- a heating region with an open flame through which the clothing wire is arranged to be guided in a pass-through direction;
- a quenching bath having a quenching liquid following the heating region;
- a tempering apparatus following the quenching bath;
- and
- a transition region arranged between a region of contact with the open flame and an entry into the quenching liquid wherein the transition region is constructed for flushing around the clothing wire with a protective medium comprising the quenching liquid, and wherein the transition region includes a wire conduit tube or a wire conduit channel, through which the quenching liquid is arranged to be conveyed in the direction of the heating region.
