Abstract

Beschrieben wird ein Verfahren zur Handhabung eines Schußfadens bei Webmaschinen, wobei ein vorderer Abschnitt eines in ein Webfach eingebrachten Schußfadens bei Austritt aus dem Webfach einen ersten Schußwächter passiert und in den Kanal einer Streckdüse eingesaugt wird, am Austritt des Kanals der Streckdüse ein zweiter Schußwächter angeordnet ist, wobei durch die Schußwächter eine vollständige Überwachung des Fadens auf Fadenhemmung und Fadenbruch erfolgt, wobei erfindungsgemäß, unter Vermeidung von Hilfskettfäden (Fangleisten), bei erfolgreichem Eintrag des Schußfadens eine in Schußrichtung vor dem ersten Schußwächter angeordnete Absaugvorrichtung aktiviert wird und gleichzeitig die Streckdüse deaktiviert wird, so daß der vordere Fadenabschnitt von der Absaugvorrichtung erfaßt wird, von einer Schneidevorrichtung geschnitten wird und der abgeschnittene Fadenabschnitt durch die Absaugvorrichtung abtransportiert wird.A method for handling a weft thread is described Looms, a front portion of which is placed in a shed Weft passes a first weft guard when leaving the shed and is sucked into the duct of a stretching nozzle, at the outlet of the duct of the stretching nozzle a second shot guard is arranged, with one by the shot guard complete monitoring of the thread for thread inhibition and thread breakage is carried out, whereby according to the invention, while avoiding auxiliary warp threads (catch strips), at successful insertion of the weft one in the weft direction before the first Gun guard arranged suction device is activated and at the same time the Stretching nozzle is deactivated so that the front thread section of the Suction device is detected, cut by a cutting device and the cut thread section is transported away by the suction device.
