Abstract

Für eine Auflösewalze, die zum Vereinzeln von Fasem an einer Offenend-Spinnmaschine Verwendung findet, wird vorgeschlagen, daß der Gamiturdraht, bevor er auf die Auflösewalze aufgezogen wird, gehärtet ist. Weiterhin ist vorgesehen, daß der Gamiturdraht vor dem Härten spiralförmig vorgeformt ist. Darüber hinaus wird ein Verfahren zum Herstellen eines für die Erfindung verwendeten Garniturdrahtes vorgeschlagen. Dabei werden für den Beschichtungsvorgang die vorgeformten Windungen während des Beschichtens im Abstand zueinander gehalten.

Figure 00000001
For an opening roller, which is used for separating fibers on an open-end spinning machine, it is proposed that the thread wire is hardened before it is drawn onto the opening roller. Furthermore, it is provided that the gauze wire is pre-shaped in a spiral before hardening. In addition, a method for producing a clothing wire used for the invention is proposed. For the coating process, the preformed turns are kept at a distance from each other during the coating.
