Document Type and Number:

WIPO Patent Application WO/1990/000211

Kind Code:

A1

Abstract:

This invention relates to a water jet nozzle applicable to a high-speed loom. A weft thread feeder in a conventional water jet nozzle for a loom consists of hardened steel at best, and a water jet current straightening stabilizer in such a water jet nozzle is formed out of a resin in many cases. When such a conventional water jet nozzle is used for a high-speed loom, the wear resistance and corrosion resistance of these parts proves to be insufficient, and these parts do not stand long. Therefore, it is an object of the present invention to provide a water jet nozzle for looms, which has a high wear resistance and a high corrosion resistance and an excellent high-speed stability. To achieve this object, the present invention provides a water jet nozzle for looms, in which a member, which consists of an orifice and a stabilizer formed integrally out of a material of a high hardness and a high corrosion resistance, is incorporated, a needle formed out of a material of a high hardness and a high corrosion resistance being also incorporated in the water jet nozzle. The present invention is effectively used, especially in a superhigh-speed loom.
