Description

Monolithisches Fachhalteelement zu dem Webrotor einer ReihenfachwebmaschineMonolithic shed holding element for the weaving rotor of a row shed weaving machine
Die Erfindung bezieht sich auf ein monolithisches Fachhalteelement zu dem Webrotor einer Reihenfachwebmaschine gemäss Oberbegriff von Anspruch 1 sowie auf einen Webrotor und eine Webmaschine mit erfindungsgemässen Fachhalteelementen.The invention relates to a monolithic shed holding element for the weaving rotor of a row shed loom according to the preamble of claim 1 and to a weaving rotor and a loom with shed holding elements according to the invention.
Reihenfachwebmaschinen sind Mehrphasenwebmaschinen (siehe z.B. EP 0 013 321), bei welchen mehrere gegeneinander stufenweise verschobene Schussfäden in wanderndeRow shed looms are multi-phase looms (see e.g. EP 0 013 321), in which several weft threads that are gradually shifted against each other move into moving ones
Webfächer eingetragen werden, wobei mit einem Webrotor eine Mehrzahl von Fächern gebildet wird, die sich jeweils über die gesamte Webbreite erstrecken. Der walzenförmige Webrotor weist axial ausgerichtete Lamellenkämme mit Anschlags- bzw. Führungslamellen auf. Zwischen den Führungslamellen sind abwechselnd Fachhalteorgane angeordnet, welche die Hoch- bzw. Tieffachstellung der Kettfäden festlegen.Weaving compartments are entered, a plurality of compartments being formed with a weaving rotor, each of which extends over the entire weaving width. The roller-shaped weaving rotor has axially aligned lamella combs with stop or guide lamellae. Between the guide lamellae, shed retaining elements are alternately arranged, which fix the up or down position of the warp threads.
Aus der EP 0 196 349 sind monolithische Fachhalteelemente bekannt, die jeweils einen Kettfadenführungsabschnitt aufweisen, der aus einem Durchgang zwischen zwei Vorsprüngen besteht, wobei der Boden des Durchgangs die Hochfachauflagefläche für Kettfäden bildet. Die Vorsprünge haben die Funktion der oben erwähnten Führungslamellen. Der Schusseintrag erfolgt mittels eines Luftstrahls. Für einzelne Fachhalteelemente ist jeweils eine Form derart vorgesehen, dass für eine Hilfsblasdüse Raum frei gehaltenen ist.Monolithic shed holding elements are known from EP 0 196 349, each of which has a warp thread guide section, which consists of a passage between two There are projections, the bottom of the passage forming the high compartment support surface for warp threads. The projections have the function of the guide slats mentioned above. The shot is inserted using an air jet. A shape is provided for individual compartment holding elements in such a way that space is kept free for an auxiliary blowing nozzle.
Diese bekannten monolithischen Fachhalteelemente werden mit Vorteil als Presslinge aus keramischem Material gefertigt. Statt ganz aus Keramik kann dasThese known monolithic shelf holding elements are advantageously manufactured as compacts from ceramic material. Instead of entirely made of ceramic, this can be done
Fachhalteelemente beispielsweise aus Leichtmetall bestehen, wobei zumindest der Kettfadenführungsabschnitt mit keramischem oder einem anderen widerstandsfähigen Material beschichtet sein uss.Compartment holding elements consist, for example, of light metal, at least the warp thread guide section being coated with ceramic or another resistant material.
Die Hilfsdüse, die einen Luftkanal sowie eine geeignete Düsenöffnung aufweist, kann nicht oder nur mit grossem Aufwand aus keramischem Material hergestellt werden. Anders als bei den Fachhalteelementen besteht aber die kostengünstige Möglichkeit, die Hilfsdüsen aus Kunststoff zu fertigen. Wegen schneller Abnutzung durch dieThe auxiliary nozzle, which has an air duct and a suitable nozzle opening, cannot be produced from ceramic material or can only be produced with great effort. In contrast to the shelf holding elements, there is the cost-effective option of manufacturing the auxiliary nozzles from plastic. Because of rapid wear from the
Kettfäden ist Kunststoff für die Fachhalteelemente nicht verwendbar.Warp threads, plastic cannot be used for the compartment holding elements.
Die Erfindung beruht auf der Aufgabe, Fachhalteelemente zu schaffen, die kostengünstiger herstellbar sind. Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Dadurch, dass die Hilfsdüse im Fachhalteelement integriert ist und nicht als separates Element hergestellt werden muss, ergibt sich eine Kostenreduktion. Eine entsprechende Ausführung des Fachhalteelements aus keramischem Material wäre sehr teuer, da die für die Düse nötige Bohrung nur unter hohen Kosten erzeugbar wäre.The invention is based on the task of creating compartment holding elements that can be manufactured more cost-effectively. This object is solved by the features of claim 1. The fact that the auxiliary nozzle is integrated in the compartment holding element and does not have to be manufactured as a separate element results in a cost reduction. A corresponding design of the compartment holding element made of ceramic material would be great expensive, since the bore required for the nozzle could only be produced at high costs.
Ein weiterer Vorteil der integrierten Düse ist, dass zwischen Düse und Schussfadenkanal des Fachhalteelements keine problematische Übergangsstelle vorliegt. Der Schussfaden führt während des Eintrags eine über den gesamten Querschnitt des Schussfadenkanals hin- und herpendelnde Schwingbewegung aus. Damit der Faden bei den Berührungen mit den Fachhalteelementen möglichst keine Beschädigung erleidet, muss die Kontur des Kanals fadenfreundlich ausgebildet sein. In einem Spalt an der Übergangsstelle zwischen Düse und Schussfadenkanal können Fasern des Schussfadens hängen bleiben. Eine solche problematische Stelle wäre daher nicht fadenfreundlich. Als eine weitere Aufgabe der Erfindung kann daher die Beseitigung einer derartigen Übergangsstelle angesehen werden.Another advantage of the integrated nozzle is that there is no problematic transition point between the nozzle and the weft thread channel of the compartment holding element. During the insertion, the weft carries out an oscillating movement that oscillates back and forth over the entire cross section of the weft thread channel. So that the thread does not suffer any damage when it comes into contact with the compartment holding elements, the contour of the channel must be thread-friendly. Fibers of the weft thread can get caught in a gap at the transition point between the nozzle and the weft thread channel. Such a problematic area would therefore not be thread-friendly. The elimination of such a transition point can therefore be regarded as a further object of the invention.
