Abstract

Bei einem Spinnrotor werden die nicht zu beschichtenden Bereiche des Rotortellers (2) mit einer Abdeckschicht (7, 8) versehen, die nach der Beschichtung des Rotortellers (2) mit einer verschleiss- und spinntechnisch geeigneten Schicht, vor oder während der Endbearbeitung des Rotortellers (2) wieder entfernt wird. Es werden also nur diejenigen Bereiche des Rotortellers (2) mit einer Beschichtung versehen, die im Betrieb einem erhöhten Verschleiss ausgesetzt sind und an die spinntechnisch besondere Anforderungen, beispielsweise hinsichtlich der Oberflächenbeschaffenheit, gestellt werden. Durch die erfindungsgemässe Verfahrensführung ist keine gesamthafte galvanische Beschichtung des Rotortellers mehr erforderlich. Auf Wachsmasken und dergleichen Hilfmittel kann verzichtet werden. Die Entfernung der Abdeckschicht erfolgt vor oder während der Endbearbeitung des Rotortellers (2). Als Abdeckschicht kommen ein Lack auf Basis organischer Filmbildner oder eine wiederverwendbare Kunststoffabdeckung (7, 8) zur Anwendung.

Figure 00000001
In the case of a spinning rotor, the areas of the rotor plate (2) that are not to be coated are provided with a covering layer (7, 8), which after coating the rotor plate (2) with a layer suitable for wear and spinning, before or during the finishing of the rotor plate ( 2) is removed again. Thus, only those areas of the rotor plate (2) are provided with a coating which are exposed to increased wear during operation and which are subject to special requirements in terms of spinning technology, for example with regard to the surface quality. As a result of the procedure according to the invention, an overall galvanic coating of the rotor plate is no longer necessary. Wax masks and the like can be dispensed with. The cover layer is removed before or during the finishing of the rotor plate (2). A coating based on organic film formers or a reusable plastic cover (7, 8) are used as the covering layer.
