【発明の名称】水流交絡装置で極微細な液体噴流を発生させるためのノズルボディおよび噴流交絡のための方法
Document Type and Number:
Japanese Patent JP2003508644
Kind Code:
A
Abstract:
The water jet streams on a nozzle beam for the hydrodynamic water needling are formed inside a nozzle body (14, 31) which extends over the length of the nozzle beam. The material of the nozzle strip (14) is, in general, made of high-grade steel in which the holes (30) for the nozzle jet streams are punched or drilled. According to the invention, the material of the nozzle body (31) is made of hard metal, ceramic or of a material having similar properties such as sapphire, and the holes are then made using a laser beam or an electrical discharge machining method or a diamond drill. The nozzle body can be provided as a nozzle strip or only as one individual unit that produces the respective water jet stream. This ensures not only a high level of abrasive resistance of the hole edge areas, but very smooth and, in particular, longer hole walls which can also be produced with sharp-edges and without the formation of burrs.
