Die Spindelschaftbohrung 3.1 endet mit Abstand unterhalb des radial verlaufenden Fadenkanals 5.1 und geht in den Kanalabschnitt 3.2 über.A thread guide tube 8 is inserted into the spindle shaft bore 3.1, see also FIG. 1a. that of one that ends at a distance below the thread guide channel 5.1, with compressed air is acted upon ring channel, at the upper end of an eccentric or sloping channel sections 3.2 to a substantially central in the turntable lead injector nozzle 9 used, the nozzle opening is directed into the thread channel 5.1. The spindle shaft bore 3.1 ends at a distance below the radial thread channel 5.1 and passes into channel section 3.2.

Unterhalb der Spindel ist ein Kupplungsstück 10 angeordnet, das, wie in Figur 1 dargestellt, an das untere Ende der Wirtelbohrung 4.1 anschließbar ist, durch die im übrigen auch das Fadenführungsrohr 8 unter Freilassung eines Ringspaltes hindurchgeführt ist.A coupling piece 10 is arranged below the spindle, which, as shown in FIG. is connectable to the lower end of the whirl hole 4.1, by the way that also Thread guide tube 8 is passed with the release of an annular gap.

Das Umlenkstück 10 ist mit einem an das Fadenführungsrohr 8 anschließbaren Fadenkanal 11 für eine von einer nicht dargestellten Gatterspule abgezogenen Fadenkomponente (Pfeil F1) und mit einem an eine nicht dargestellte Druckluftquelle (Pfeil F2) angeschlossenen Druckluftkanal 12 versehen, der über im einzelnen nicht dargestellte Anschlußkanäle zum Zwecke der Fadendurchfädelung an den das Fadenführungsrohr 8 umgebenden Ringkanal 3.1 des Spindelschaftes 3 anschließbar ist.The deflection piece 10 has a thread channel that can be connected to the thread guide tube 8 11 for a thread component drawn off from a creel (not shown) (arrow F1) and connected to a compressed air source, not shown (arrow F2) Compressed air channel 12 provided for the via Purpose of threading the ring channel surrounding the thread guide tube 8 3.1 of the spindle shaft 3 can be connected.
