Abstract

Die Massnahme zur Beeinflussung der Strömung im Garnführungskanal besteht darin, dass nach der Faserführungsfläche zum Spindelkonus und durch die Einlassmündung in den Spindelkanal die Strömung im Spindelkanal durch Mittel derart beeinflusst wird, dass das Eintrittsverhalten der Faserenden und das Abspreizen der hinteren Faserenden in schwacher bis unterdrückter Gegenströmung oder in Mitströmung geschieht und diese Mittel strömungsaktive Verbindungen zwischen dem Ausströmungskanal und dem Spindelkanal sind, beispielsweise Durchgänge mittels Bohrungen oder durch Verwendung von fluiddurchlässigen Sintermaterialien.

Figure 00000001
The measure for influencing the flow in the yarn guide channel is that after the fiber guide surface to the spindle cone and through the inlet opening in the spindle channel, the flow in the spindle channel is influenced by means such that the entry behavior of the fiber ends and the spreading of the rear fiber ends in weak to suppressed counterflow or occurs in the co-flow and these means are flow-active connections between the outflow channel and the spindle channel, for example passages by means of bores or by using fluid-permeable sintered materials.
