Abstract (en)
[origin: WO2004106605A1] The invention relates to a ceramic nozzle core and a method for producing a ceramic nozzle core which is part of a device used for producing loop yarn. The inventive ceramic nozzle core is embodied with an approximately constant wall thickness and a reduced size so as to perform the central functions of the yarn processing duct comprising air injection and a yarn outlet for forming loops while being produced in a molding process. In a particularly preferred method, the ceramic nozzle core is injection-molded with high precision. The inventive ceramic nozzle core can be configured in a miniaturized fashion and as part of a two-piece nozzle core, the ceramic nozzle core being inserted into an outer nozzle core jacket. The two-piece nozzle core can be incorporated into a housing known in prior art, for example, as a replaceable nozzle core.
