Abstract

Die Erfindung betrifft eine Webmaschine mit pneumatischem Schußfadeneintrag, bei der über die Webbreite verteilt eine Anzahl von einzelnen Stützdüsen angeordnet ist. Die Webmaschine enthält ein Profilriet mit einer von der Rietvorderkante gegen die Gewebeanschlagkante vorsprin­ genden Nase. Die Stützdüsen sind als Flachstrahldüsen ausgebildet und weisen einen zentralen verstärkten Kern auf, an den sich seitlich fächerartige flache Strahlen von verringerter Strahltiefe anschließen. Diese Flach­ strahlen decken jeweils abschnittsweise einen als Führungskanal für den einzutragenden Schußfaden dienenden Raum zwischen Rietvorderkante und Nase vorhangartig ab. Die besondere Form der Flachstrahlen wird durch eine Kerbe im Düsenkörper der Stützdüsen bewirkt, in deren mittlerem Teil die Strahlaustrittsöffnung liegt und deren einander entgegengesetzt verlaufende Zweige zu ihren außenliegenden Enden flach auslaufen. The invention relates to a loom with pneumatic Weft thread entry, distributed over the width of the weave a number of individual support nozzles is arranged. The Weaving machine contains a profile reed with one of the Project the front edge of the reed against the fabric stop edge nose. The support nozzles are as flat jet nozzles trained and have a central reinforced core on the fan-shaped flat rays on the side of reduced beam depth. This flat rays cover a section in sections as Guide channel for the weft thread to be entered Space between the front edge of the reed and the nose curtain-like. The special shape of the flat rays is characterized by a Notch in the nozzle body of the support nozzles causes in their middle part is the beam outlet opening and their mutually opposite branches to theirs taper the outer ends flat.
