Abstract

Eine Garnabzugsdüse für Offenend-Rotorspinnvorrichtungen enthält eine gewölbte Kontaktfläche (19), welche ein abzuziehendes und dabei zugleich umlaufendes Garn (14) umlenkt. Die Kontaktfläche (19) ist durch wenigstens eine abrupte Vertiefung (21) derart unterbrochen, dass das Garn (14) in Umlaufrichtung kurzzeitig seinen Kontakt zur Kontaktfläche (19) verliert. Die Kontaktfläche (19) ist in Umlaufrichtung des Garnes bis zur abrupten Vertiefung (21) als sanft ansteigende, sich über einen Umfangswinkel von wenigstens 45° erstreckende Erhebung (22) ausgebildet.

Figure 00000001
A Garnabzugsdüse for open-end rotor spinning devices includes a curved contact surface (19), which deflects a deducting and at the same time revolving yarn (14). The contact surface (19) is interrupted by at least one abrupt depression (21) such that the yarn (14) momentarily loses its contact with the contact surface (19) in the direction of rotation. The contact surface (19) is formed in the direction of rotation of the yarn to the abrupt depression (21) as a gently rising, over a circumferential angle of at least 45 ° extending elevation (22).
