Abstract

CANAL DE GUIA DE FIBRA PARA UM DISPOSITIVO DE FIAçãO DE EXTREMIDADE ABERTA E MéTODO PARA A PRODUçAO DE UM CANAL DE GUIA DE FIBRA A presente invenção refere-se a um canal de guia de fibra para um dispositivo de fiação de extremidade aberta para a produção de tal canal de guia de fibra. Os canais de guia de fibra são conhecidos per se e servem para o transporte pneumático de fibras individuais que são cardadas a partir de uma montagem de fibra de alimentação por meio um cilindro de abertura que gira em um alojamento de cilindro de abertura para um rotor de fiação que gira à alta velocidade em um alojamento de rotor que pode ser submetido a uma pressão negativa. De acordo com a presente invenção, o canal de guia de fibra (13) é configurado como um corpo oco cujo diâmetro interno diminui na direção de seu orifício (26). O canal de guia de fibra 1(13) é produzido de acordo com um método de fabricação no qual uma primeira forma de peça em bruto superdimensionada é produzida por meio de moldagem à injeção de uma mistura de um material concrecionável e um aglutinante. A dita peça em bruto é convertida em uma forma intermediária porosa por meio da remoção do aglutinante, e trazida para uma forma final que requer pouco acabamento por meio de uma concreção.FIBER GUIDE CHANNEL FOR AN OPEN END WIRING DEVICE AND METHOD FOR PRODUCING A FIBER GUIDE CHANNEL The present invention relates to a fiber guide channel for an open end wiring device for the production of such a fiber guide channel. Fiber guide channels are known per se and serve for the pneumatic transport of individual fibers that are carded from a feed fiber assembly by means of an opening cylinder that rotates in an opening cylinder housing for a rotor. high-speed spinning in a rotor housing that can be subjected to negative pressure. According to the present invention, the fiber guide channel (13) is configured as a hollow body whose inner diameter decreases in the direction of its hole (26). Fiber guide channel 1 (13) is produced according to a manufacturing method in which a first oversized blank is produced by injection molding a mixture of a concratable material and a binder. Said blank is converted into a porous intermediate form by removing the binder, and brought into a final form that requires little finishing by means of a concrete.
