Abstract

PCT No. PCT/DE98/03412 Sec. 371 Date Jul. 14, 1999 Sec. 102(e) Date Jul. 14, 1999 PCT Filed Nov. 18, 1998 PCT Pub. No. WO99/27171 PCT Pub. Date Jun. 3, 1999The invention relates to an auxiliary blow nozzle for air jet weaving machines which permits a symmetric division of the warp, said division protecting the structure of the warp threads, when the blow nozzle is immersed in the warp. To this end, an envelope curve (5) which describes the free end (1b) of the nozzle body (1) and which has a radius (R1) runs at an angle ( alpha ) relative to the longitudinal axis (4a) of the approximately elliptic cross-section of a nozzle body end area (1a). The surfaces (6, 7) originating from the envelope curve (5) slope downward on both sides to the outer periphery (4) in a manner similar to a roof, and said surfaces (6, 7) thus enclose an angle ( beta ). The respective surface (6, 7) having a radius (R2) graduates into the outer periphery (4). A radius (R3) connects radius (R1) of the envelope curve (5) to the outer periphery (4), and each surface (6, 7) constructs an arc-shaped surface section (6a, 7a) which slopes downward at an angle ( gamma ) relative to the outer periphery (4). The graduations of said surface sections into the adjacent surfaces (6, 7) and into the outer periphery (4) are rounded.

Description

Die Erfindung betrifft eine Hilfsblasdüse für eine Luftdüsenwebmaschine mit einem eine Eintrittsöffnung aufweisenden Luftströmkanal, mit einer im Endbereich der Düse vorhandenen Austrittsöffnung mit einer der Längsmittenachse des Luftströmkanals gegenüber abgewinkelten Längsmittenachse, mit wenigstens einen vom Endbereich ausgehenden, in Richtung der Eintrittsöffnung hin verlaufenden Längenabschnitt mit einem etwa elliptischen Außenumfang, mit einer die Längsmittenachse der Austrittsöffnung teilweise umgreifenden und das freie Ende des Endbereiches beschreibenden Hüllkurve, die einen Radius R1 besitzt und wobei die Hüllkurve zu angrenzenden Flächen verrundet ist.
Eine solche Hilfsblasdüse ist aus dem US-Patent 4,987,930 bekannt.The invention relates to an auxiliary blowing nozzle for an air jet weaving machine with an air flow channel having an inlet opening, with an outlet opening provided in the end region of the nozzle with a longitudinal center axis angled with respect to the longitudinal center axis of the air flow channel, with at least one longitudinal section starting from the end region and running in the direction of the inlet opening with approximately elliptical outer circumference, with an envelope curve which partially encompasses the longitudinal center axis of the outlet opening and describes the free end of the end region, and which has a radius R 1 and the envelope curve is rounded to adjacent surfaces.
Such an auxiliary blowing nozzle is known from US Pat. No. 4,987,930.

In Luftdüsenwebmaschinen werden Hilfsblasdüsen mit den vorstehend bekannten Merkmalen eingesetzt.
Die Längsachse der Austrittsöffnung für den Luftstrom liegt dabei rechtwinklig zum Verlauf der Hüllkurve des freien Endes der Hilfsblasdüse bzw. rechtwinklig zur Längsmittenachse des etwa elliptischen Außenumfangs des Düsenkörpers.
Für den Praxiseinsatz der Hilfsblasdüsen bedeutet eine solche Ausbildung, daß zur optimalen Wirksamkeit der Luftströmung auf den in einen Eintragskanal eines Webblattes einzutragenden Schußfaden die Längsmittenachse der Austrittsöffnung in einem Winkel von einigen Winkelgraden in der Horizontalen zu den Kettfäden einer Webkette verdreht bzw. in einigen Winkelgraden zum Eintragskanal des Webblattes hin ausgerichtet ist.
Eine solche Ausrichtung besitzt aber den Nachteil, daß beim Eintauchen der Hilfsblasdüsen in das Unterfach einer Webkette nicht alle betreffenden, von dem freien Ende der Düse gestreiften oder sogar kurzzeitig angehobenen Kettfäden von diesem Ende etwa symmetrisch abgleiten und daß das webtechnisch bedingte, immer wiederkehrende Eintauchen der Hilfsblasdüsen in die Unterkette bei einer nicht parallel zum Verlauf der Kettfäden ausgerichteten Längsachse des etwa elliptischen Außenumfangs zum Beschädigen der Struktur der betreffenden Kettfäden führt.
Diese Beschädigungen sind in dem hergestellten Gewebe erkennbar und stellen sich schließlich im Gewebe als Gewebefehler dar.Auxiliary blowing nozzles with the features known above are used in air jet weaving machines.
The longitudinal axis of the outlet opening for the air flow is at right angles to the course of the envelope curve of the free end of the auxiliary blowing nozzle or at right angles to the longitudinal center axis of the approximately elliptical outer circumference of the nozzle body.
For the practical use of auxiliary blowing nozzles, such a design means that, for optimal effectiveness of the air flow on the weft thread to be inserted into an insertion channel of a reed, the longitudinal center axis of the outlet opening is rotated at an angle of a few degrees in the horizontal to the warp threads of a warp or in a few degrees Entry channel of the reed is aligned.
However, such an alignment has the disadvantage that when the auxiliary blowing nozzles are immersed in the lower shed of a warp, not all of the warp threads concerned, striped from the free end of the nozzle or even briefly raised, slide approximately symmetrically from this end and that the weaving-related, recurring immersion of the Auxiliary blowing nozzles in the lower chain in the case of a longitudinal axis of the approximately elliptical outer circumference which is not aligned parallel to the course of the warp threads leads to damage to the structure of the relevant warp threads.
This damage can be seen in the fabric produced and ultimately presents itself in the fabric as a tissue defect.

Bekannt sind des weiteren aus der EP 0 145 824 Hilfsblasdüsen, die ebenfalls einen strukturellen Aufbau gemäß dem Oberbegriff von Patentanspruch 1 besitzen. Mit der konstruktiv festgelegten abgewinkelten Längsmittenachse der Austrittsöffnung gegenüber dem Verlauf der das freie Ende des Düsenkörpers bildeten Hüllkurve bzw. gegenüber der Längsachse des etwa elliptischen Querschnitts des Düsenkörpers, die hier kongruent zur Hüllkurve ist, soll erreicht werden,

  • a) eine optimale Wirksamkeit der Luftströmung auf den Schußfaden und
  • b) eine optimale Anpassung der Außenkontur des Düsenkörper-Endbereiches an den Verlauf der Kettfäden.
    • Auxiliary blowing nozzles are also known from EP 0 145 824, which also have a structural design according to the preamble of claim 1. The constructively defined angled longitudinal center axis of the outlet opening with respect to the course of the envelope curve forming the free end of the nozzle body or with respect to the longitudinal axis of the approximately elliptical cross section of the nozzle body, which here is congruent with the envelope curve, is to be achieved,
  • a) optimal effectiveness of the air flow on the weft and
  • b) an optimal adaptation of the outer contour of the nozzle body end region to the course of the warp threads.

    • Von Nachteil ist hierbei, daß die Längsmittenachse der Austrittsöffnung in einem Winkel von mehr als 90 ° zur Längsachse der elliptischen Form des Düsenkörper-Endabschnittes liegt. Das bedeutet, daß die Austrittsöffnung schwieriger zu fertigen ist, als eine rechtwinklig zur Längsachse des elliptischen Außenumfanges ausgerichtete Austrittsöffnung.The disadvantage here is that the longitudinal center axis of the outlet opening at an angle of is more than 90 ° to the longitudinal axis of the elliptical shape of the nozzle body end section. This means that the outlet opening is more difficult to manufacture than one perpendicular to it Exit opening aligned along the longitudinal axis of the elliptical outer circumference.

    Vor diesem Hintergrund ist es Aufgabe der Erfindung, eine Hilfsblasdüse, insbesondere für Luftdüsenwebmaschinen zu schaffen, die beim Eintauchen in die Webkette ein symmetrisches, die Struktur der Kettfäden schonendes Teilen der Webkette ermöglicht.
    Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.    Against this background, it is an object of the invention to provide an auxiliary blowing nozzle, in particular for air-jet weaving machines, which, when immersed in the warp, enables the warp to be divided symmetrically and protects the structure of the warp threads.
    The object is achieved by the characterizing features of claim 1.

    Durch die erfindungsgemäße Ausbildung des Endbereiches der Hilfsblasdüse wird auf vorteilhafte Weise erreicht, daß die vom Eintauchen der Hilfsblasdüse in die Webkette betroffene Schar von Kettfäden symmetrisch geteilt wird, ohne daß die Struktur der betreffenden Kettfäden in irgendeiner Weise beeinträchtigt wird.Due to the inventive design of the end region of the auxiliary blowing nozzle is on advantageously achieved that by immersing the auxiliary blowing nozzle in the warp affected group of warp threads is divided symmetrically without the structure of the affected warp threads in any way.

    Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels erläutert.The invention is explained below using an exemplary embodiment.

    In weiterer Ausgestaltung der Erfindung können die Flächen 6.7 nach außen leicht gewölbt sein oder aber ebenflächig ausgebildet sein. Die Wölbung kann dabei einen Radius R4 besitzen, der kleiner als 1000 µm ist.In a further embodiment of the invention, the surfaces 6.7 can be slightly curved outwards or they can be flat. The curvature can have a radius R 4 that is less than 1000 microns.
