Die Erfindung betrifft ein Fachhalteelement zu dem Webrotor einer Reihenfachwebmaschine gemäss Oberbegriff von Anspruch 1 sowie einen Webrotor und eine Webmaschine mit erfindungsgemässen Fachhalteelementen.The invention relates to a compartment holding element Weaving rotor of a row shed weaving machine according to the generic term of claim 1 and a weaving rotor and a weaving machine with compartment holding elements according to the invention.

Reihenfachwebmaschinen sind Mehrphasenwebmaschinen (siehe z.B. EP 0 013 321), bei welchen mehrere gegeneinander stufenweise verschobene Schussfäden in wandernde 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.Row shed weaving machines are multi-phase weaving machines (see e.g. EP 0 013 321), in which several against each other gradually shifted weft threads in wandering Weaving subjects are entered, with a weaving rotor a plurality of subjects are formed, each one extend across the entire width of the weave. The roller-shaped Webrotor has axially aligned lamella combs Stop or guide slats on. Between Guide lamellae are alternately specialist holding units arranged, which is the high or low position of the Set warp threads.

Aus der EP 0 196 349 sind 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 Luft. Für einzelne Fachhalteelemente ist jeweils eine Form derart vorgesehen, dass Raum für eine Hilfsblasdüse frei bleibt.Shelf holding elements are known from EP 0 196 349 which each have a warp thread guide section, the consists of a passage between two protrusions, the floor of the passage being the high shelf forms for warp threads. The ledges have the function of the guide blades mentioned above. The weft entry takes place by means of air. For individual shelf holding elements each provided a shape so that space for one Auxiliary blowing nozzle remains free.

Bei bekannten Fachhalteelemente ergeben sich immer wieder Webfehler, wenn beispielsweise bei einem vorgesehenen Wechsel von der Hoch- zur Tieffachlage sich ein Kettfaden nicht richtig bewegen lässt. Eine solche Fehlbewegung ist einer ungenügend ausgestalteten Form der Fachhalteelemente zuzuschreiben.Known shelf holding elements always result Web errors, for example, when a provided A warp thread changes from the high to the low position doesn't move properly. Such is a wrong move an insufficiently designed form of Attributes of compartmentalization.

Fig.3) vorgesehen sind. Durch den Webrotor 5 wird das Fachhalteelement 1 in Richtung des Pfeils P bewegt. Die Quernut 11' in der Auflagefläche 11 hat keine funktionelle Bedeutung und besteht lediglich aus herstellungstechnischen Gründen.The compartment holding element 1 has the following parts: Hochfachauflagefläche 11 for warp threads 3, between two ear-shaped projections 12 and 13 is arranged; Weft thread channel 14 with the lateral outlet opening 140 and with the one indicated by the arrow F. Direction of entry; and two not fully shown Parts 15, 15 'which are used to fasten the compartment holding element 1 are provided in a weaving rotor 5 (see FIG. 3). By the weaving rotor 5 becomes the compartment holding element 1 in the direction of the arrow P moves. The transverse groove 11 'in the contact surface 11 has no functional meaning and only exists for manufacturing reasons.

Zur Beschreibung des Fachhalteelements 1 werden anhand der Fig.1 zusätzlich folgende Bezeichnungen eingeführt: Tieffachzone 16, Unterteil 17, Hinterteil 18, Oberteil 19 und Vorderteil 20. Der Unterteil 17 umfasst die Tieffachzone 16.The description of the compartment holding element 1 will be based on 1 the following designations have also been introduced: Deep compartment zone 16, lower part 17, rear part 18, upper part 19 and front part 20. The lower part 17 comprises the Deep compartment zone 16.

Alle in Fig.1 mit ausgezogenen Linien dargestellten Kanten hat man sich als abgerundet vorzustellen. Insbesondere ist der als Konfusor ausgebildete Rand 141 an der Eintrittsseite des Schussfadenkanals 14 stark abgerundet, wie dies in Fig.2 zu sehen ist.All shown in Fig. 1 with solid lines Edges have to be imagined as rounded. In particular, the edge 141 designed as a confuser is strong on the entry side of the weft channel 14 rounded, as can be seen in Fig.2.

Fig.3 zeigt neben zwei auf dem Webrotor 5 befestigten Fachhalteelementen 1 und 1' eine zwischen diesen angeordnete Anschlagslamelle 2. Die am weitest aussen liegenden Punkte der Anschlagslamellen 2 und der Fachhalteelemente 1 bewegen sich auf den Kreisen 2a bzw. 13a. Die Kettfäden 3 in der Hochfachlage sind mit 3', jene in der Tieffachlage mit 3" bezeichnet. Beim Fachhalteelementen 1 befindet sich der Schussfaden 4 im Schussfadenkanal 14; beim Fachhalteelementen 1' ist er ausserhalb und in jener Lage, aus der er durch die Anschlagslamelle 2 am Tuchrand 8 des Gewebes 7 angeschlagen werden kann. Das Vortuch 7a, das zwischen einer Stützfläche 6 und dem Tuchrand 8 liegt, erfährt beim Anschlagen eine vorübergehende Verschiebung in eine Lage über der Stützfläche 6. Aus dieser Lage federt das Vortuch 7a wieder zurück.3 shows two attached to the weaving rotor 5 Compartment holding elements 1 and 1 'one between these arranged stop lamella 2. The farthest outside lying points of the stop slats 2 and Compartment holding elements 1 move in circles 2a or 13a. The warp threads 3 in the high shed position are 3 ', those in the low compartment with 3 " Compartment holding elements 1, the weft thread 4 is located in the Weft channel 14; for shelf holding elements 1 'it is outside and in the position from which he is through the Stop lamella 2 on the cloth edge 8 of the fabric 7 can be posted. The blanket 7a between a support surface 6 and the cloth edge 8, experiences when struck a temporary shift into one Position above the support surface 6. This springs from this position Screen 7a back again.

Gemäss der Erfindung ist an dem Vorderteil 20 des Fachhalteelements 1 eine zu der Auflagefläche 11 führende Vorderkante als Gleitkante 200 für die Kettfäden ausgebildet. Diese Kante 200 verläuft entlang eines Kurvenstücks 201, auf dem die Krümmungsradien nicht wesentlich von einem Mittelwert abweichen, so dass der grösste Krümmungsradius nicht grösser als rund das Zehnfache des kleinsten ist. Somit gibt es an der Kante 200 beispielsweise keine nasenartige Erhebung, die die Bewegung des Kettfadens 3 bei einem Wechsel von der Hochzu der Tieffachlage beeinträchtigen könnte. Quer zu dem Kurvenstück 201 sind die Krümmungsradien der Gleitkante 200 relativ klein, aber grösser als die Breite b des Fachhalteelements 1. Dank der besonderen Formgebung der Gleitkante 200 bleibt ein Springen oder Hängenbleiben des Kettfadens aus.According to the invention on the front part 20 of the Compartment holding element 1 leading to the contact surface 11 Front edge as a sliding edge 200 for the warp threads educated. This edge 200 runs along one Curve piece 201 on which the radii of curvature are not deviate significantly from an average, so that the largest radius of curvature is not greater than around that Is ten times the smallest. So there is on the edge 200, for example, no nasal elevation that the Movement of the warp thread 3 when changing from the up to could affect the low compartment. Cross to that Curve piece 201 are the radii of curvature of the sliding edge 200 relatively small, but larger than the width b of the Compartment holding element 1. Thanks to the special shape of the The sliding edge 200 remains a jumping or getting stuck Warp thread.

Die Vorsprünge 12 und 13 sind in Fig.1 als "Ohren" dargestellt, die eine konstante Dicke aufweisen. Mit Vorteil wird eine Form vorgesehen, bei der sich diese Ohren 12 und 13 jeweils im oberen Bereich zur Spitze 120 bzw. 130 hin verjüngen. Um mehr Platz für die Kettfäden 3 auf der Auflagefläche 11 zu erhalten, kann auch eine Verjüngung in der umgekehrten Richtung im unteren Bereich der Ohren 12 und 13 vorgesehen werden, so dass die Breite der Auflagefläche 11 grösser als die in Fig.1 angegebene Breite c ist. Diese Formvarianten mit Verjüngungen oben bzw. unten sind in den Zeichnungen nicht dargestellt.The projections 12 and 13 are shown as "ears" in FIG. shown that have a constant thickness. With Advantage is provided a form in which this Ears 12 and 13 each in the upper area to the tip 120 or 130 taper. To make more space for the warp threads 3 to get on the support surface 11 can also Taper in the opposite direction in the lower area the ears 12 and 13 are provided so that the width the contact surface 11 is larger than that indicated in FIG Width c is. These shape variations with tapered top or below are not shown in the drawings.

Der zahnartig geformte Hinterteil 18, dessen Spitze 181 stumpf ist, verjüngt sich gegen den Oberteil 19, der die Breite b aufweist. Die Basis des Hinterteils 18 hat die gleiche Breite b. Daher liegt bei der Öffnung 140 ein Rücksprung vom Oberteil 19 zum Hinterteil 18 vor, dank dem ein Einhaken des Kettfadens 3 beim Wechsel von der Hoch- zu der Tieffachlage ausbleibt.The tooth-shaped rear part 18, the tip 181 is blunt, tapers against the upper part 19, which the Has width b. The base of the rear part 18 has the same width b. Therefore there is an opening 140 Return from the upper part 19 to the rear part 18, thanks which a hooking of the warp thread 3 when changing from Missing up to the low bay.

Der parallel zur Oberfläche des Webrotors 5 gemessene Abstand zwischen den Spitzen 120 und 130 ist die Länge a in Fig.1. Dieser Abstand a ist grösser als bei bekannten Fachhalteelementen. Da der Abstand a zusammen mit der Winkelgeschwindigkeit des Webrotors ein minimales Zeitmass für das Einlesen der Kettfäden festlegt, lässt sich der Webvorgang bei Vorliegen eines grösseren Abstands a mit einer höheren Webgeschwindigkeit durchführen. Der Abstand a ist mindestens rund fünfmal grösser als die Breite b.The measured parallel to the surface of the weaving rotor 5 Distance between tips 120 and 130 is length a in Fig. 1. This distance a is larger than in known ones Compartment holding elements. Since the distance a together with the The angular velocity of the weaving rotor is minimal Specifies the time for reading in the warp threads the weaving process when there is a larger one Distance a with a higher weaving speed carry out. The distance a is at least five times greater than the width b.

Der vordere Vorsprung 130 zeigt in seinem oberen Bereich eine "fliehende" Stirnfläche 131, die im wesentlichen gleich gerichtet ist wie der obere Teil des Kurvenstücks 201. Dies ist von Vorteil bezüglich der oben erwähnten Bewegung des Vortuches 7a, die durch die Anschlagslamellen 2 verursacht wird. Bei bisherigen Formen des Fachhalteelements ergaben sich Störungen durch Einhaken des vorderen Vorsprungs 130 am zurückfedernden Vortuch 7a. Bei der in Fig.1 gezeigten Form tritt ein derartiges Einhaken nicht ein.The front projection 130 shows in its upper region a "fleeing" face 131, which is essentially is oriented in the same way as the upper part of the curve section 201. This is advantageous in relation to those mentioned above Movement of the blanket 7a by the Stop slats 2 is caused. With previous ones Shapes of the shelf holding element resulted from disturbances Hooking the front projection 130 on the springback Screen 7a. The shape shown in FIG. 1 occurs such hooking does not occur.

Der Unterteil 17 des Fachhalteelements 1 weist eine taillierte Tieffachzone 16 auf. Die Taillierung schafft zusätzlichen Raum für die Kettfäden 3", wodurch Behinderungen und Reibungen zwischen den Kettfäden 3" verringert werden.The lower part 17 of the compartment holding element 1 has one waisted deep compartment zone 16. The waist creates additional space for the warp threads 3 ", which Disabilities and friction between the warp threads 3 " be reduced.

Der Hinterteil 18 weist wie der Vorderteil 20 bei der Gleitkante 200 garnfreundlich gerundete Anschrägungen 180 auf. Auch für die zweite Kante 202 des Vorderteils 20 ist auf der Höhe des Schusskanals 14 eine entsprechende garnfreundliche Anschrägung vorgesehen.The rear part 18 has like the front part 20 in the Sliding edge 200 chamfer-friendly rounded bevels 180 on. Also for the second edge 202 of the front part 20 a corresponding one at the level of the firing channel 14 yarn-friendly bevel provided.

In Fig.3 ist die Bewegungsrichtung des Schussfadens 4 umgekehrt zu jener in Fig.1 (Pfeil F). Der Transport des Schussfadens 4 durch den Schusskanal 14 wird mit Hilfsblasdüsen 9 unterstützt. Diese Hilfsblasdüsen 9 sind - wie in Fig.3 zu sehen - in die Hinterteile 18 einzelner Fachhalteelemente 1 integriert.3 shows the direction of movement of the weft thread 4 reversed to that in Fig. 1 (arrow F). The transportation of the Weft 4 through the weft 14 is with Auxiliary blowing nozzles 9 supported. These auxiliary blowing nozzles 9 are - As can be seen in Figure 3 - in the buttocks 18 individual Compartment holding elements 1 integrated.

Es können auch Fachhalteelemente 1 verwendet werden, bei denen nur einer der Vorsprünge 12 oder 13 als Leitelement für die Kettfäden 3 ausgebildet ist. Der andere kann vollständig fehlen; oder es kann lediglich ein kleiner Stummel zwecks Herstellung einer stabilen Auflagefläche 11 vorhanden sein.Compartment holding elements 1 can also be used for which only one of the projections 12 or 13 as a guide element is formed for the warp threads 3. The other one can completely absent; or just a small one Stub for the purpose of creating a stable support surface 11 be present.

Das beschriebene Fachhalteelement 1 ist ein monolithisches Gebilde. Es kann aus keramischem Material hergestellt werden. Mit Vorteil wird es jedoch aus einem Stück Metall herausgearbeitet.The compartment holding element 1 described is a monolithic structure. It can be made of ceramic material getting produced.
