Die Fig. 1a zeigt eine Frontansicht einer Reihenfachwebmaschine 1 mit einem Webrotor 6, welcher mit fachbildenden Elementen 17a gemäss Fig.2 bestückte fachbildende Abschnitte 6a, 6b aufweist. Der Webrotor 6 weist eine zentral verlaufende Welle mit einem Drehzentrum 6c auf. Die beiden fachbildenden Abschnitte 6a, 6b sind in Verlaufsrichtung des Drehzentrums 6c beabstandet. Der Webrotor 6 weist beidseitig Endabschnitte 6e, 6f auf, welche durch Haltevorrichtungen lla abgestützt sind. Die Endabschnitte 6e, 6f weisen zudem jeweils eine Schussübergabevorrichtung 7a, 7b; 8a, 8b auf, um den zugeführten Schussfäden 2a, 2b, 2c, 2d; 3a, 3b, 3c, 3d jeweils ein geöffnetes Webfach zuzuordnen. Die dargestellte Reihenfachwebmaschine 1 weist zudem eine Mittelstütze 1b auf mit einem Mittenlager 15 für den Webrotor 6.1a shows a front view of a Row shed weaving machine 1 with a weaving rotor 6, which with compartment-forming elements 17a according to Fig.2 has compartment-forming sections 6a, 6b. The web rotor 6 has a central shaft with a Center of rotation 6c. The two subject-forming sections 6a, 6b are in the direction of rotation center 6c spaced. The weaving rotor 6 has on both sides End sections 6e, 6f, which by holding devices lla are supported. The end sections 6e, 6f have in addition, in each case one shot transfer device 7a, 7b; 8a, 8b to the supplied weft threads 2a, 2b, 2c, 2d; 3a, 3b, 3c, 3d each to assign an open shed. The row shed weaving machine 1 also has one Center support 1b with a central bearing 15 for the Web rotor 6.

Wie in Fig. 1b dargestellt sind über einer Teilbreite des fachbildenden Abschnittes 6a Kettfäden 10a angeordnet. Die Gesamtheit dieser Kettfäden 10a bilden eine Webbahn 10. Die Kettfäden 10a sind, wie in Fig. 2 schematisch dargestellt, auf einem Kettbaum 13a vorrätig, wobei der Kettbaum 13a von einer Welle 13b gelagert wird. Die Kettfäden 10a verlaufen ausgehend vom Kettbaum 13a über einen Umlenkbaum 13c und über Legeelemente 14a, 14b, 14c, 14d, sowie über den fachbildenden Webrotor 6 zum Umlenkbaum 16b und weiter zum Warenbaum 18a, welcher auf einer Welle 18b gelagert ist. Der sich in Drehrichtung ω drehende Webrotor 6 weist eine Drehachse 6d auf, sowie einen fachbildenden Abschnitt 6b, welcher mit fachbildenden Elementen 17a, 17b, 17c, 17d bestückt ist. Die fachbildenden Elemente bringen die Kettfäden 10a in eine Hoch- bzw. in eine Tieflage, sodass ein Webfach gebildet wird, durch welches ein Schussfaden 2a, 3a eintragbar ist. Ein Charakteristikum der Reihenfachwebmaschine ist, dass gleichzeitig mehrere in Richtung des Drehzentrums 6c verlaufende Webfächer geöffnet sind, sodass gleichzeitig eine Mehrzahl von Schussfäden in die Kettfäden 10a eintragbar sind. Die Kettfäden 10a umschlingen einen bestimmten Winkelbereich des Webrotors 6, was als ein Umschlingungswinkel γ bezeichnet wird. Der Umschlingungswinkel γ ist im vorliegenden Ausführungsbeispiel derart gross gewählt, dass gleichzeitig vier in Richtung des Drehzentrums 6c verlaufende Webfächer geöffnet sind. Der Umschlingungswinkel γ und/oder die Anordnung der fachbildenden Elemente 17a, 17b, 17c, 17d kann auch derart gewählt sein, dass sich mehr oder weniger als viel gleichzeitig geöffnete Webfächer ergeben. Der maximal mögliche Umschlingungswinkel wird insbesondere begrenzt durch Garneigenschaften der Kettfäden 10a. Je mehr in Umfangsrichtung des Webrotors 6 verteilte fachbildende Elemente 17a, 17b, 17c, 17d angeordnet sind, an welchen die Kettfäden 10a anliegen, um so grösser wird die von den fachbildenden Elementen 17a bis 17d auf die Kettfäden 10a bewirkte Reibungskraft. Diese Kraft muss in bestimmten Grenzen gehalten werden, sodass der Umschlingungswinkel γ nicht beliebig gross gewählt werden kann. Um trotzdem die Schusseintragsleistung wesentlich zu erhöhen, wird, wie in Fig. la dargestellt, neben dem einen fachbildenden Abschnitt 6a ein zweiter fachbildender Abschnitt 6b angeordnet, wobei die beiden fachbildenden Abschnitte 6a, 6b von getrennten Schussfadeneintragsvorrichtungen mit Schussfäden 2a, 2b, 2c, 2d; 3a, 3b, 3c, 3d beschickt werden.As shown in Fig. 1b are over a section of the compartment-forming section 6a warp threads 10a arranged. The entirety of these warp threads 10a form a woven web 10. The warp threads 10a are, as in FIG. 2, schematic shown, in stock on a warp beam 13a, the Warp beam 13a is supported by a shaft 13b. The Warp threads 10a extend from the warp beam 13a a deflecting tree 13c and laying elements 14a, 14b, 14c, 14d, and via the shed weaving rotor 6 for Deflecting tree 16b and further to goods tree 18a, which on a shaft 18b is mounted. The direction of rotation ω rotating weaving rotor 6 has an axis of rotation 6d, as well a compartment-forming section 6b, which with compartment-forming elements 17a, 17b, 17c, 17d. The shed-forming elements bring in the warp threads 10a a high or a low position, so that a shed is formed, through which a weft thread 2a, 3a can be entered. A characteristic of Row shed weaving machine is that several in at the same time Shed compartments running in the direction of the center of rotation 6c are open so that a plurality of Weft threads can be inserted into the warp threads 10a. The Warp threads 10a loop around a certain angular range of the weaving rotor 6, what is known as a wrap angle γ referred to as. The wrap angle γ is in present embodiment chosen so large, that four at the same time in the direction of the center of rotation 6c running web subjects are open. The Wrap angle γ and / or the arrangement of the compartment-forming elements 17a, 17b, 17c, 17d can also be chosen so that more or less than a lot result in simultaneously opened compartments. The maximum possible wrap angle is particularly limited by yarn properties of the warp threads 10a. The more in Circumferential direction of the weaving rotor 6 distributed compartment-forming Elements 17a, 17b, 17c, 17d are arranged, on which the warp threads 10a rest, the larger that of the shedding elements 17a to 17d on the warp threads 10a caused frictional force. This force must be in certain limits are kept so that the The wrap angle γ cannot be chosen arbitrarily large can. To make the weft insertion performance essential to increase, as shown in Fig. la, next to the a compartment-forming section 6a a second compartment-forming section 6b arranged, the two compartment-forming sections 6a, 6b of separate Weft insertion devices with weft threads 2a, 2b, 2c, 2d; 3a, 3b, 3c, 3d.

In Fig. 1a sind die Schussfadenvorlagevorrichtungen 4a, 8a, 8b; 5a, 7a, 7b jeweils stirnseitig an Webrotor 6 angeordnet, derart, dass die Schussfäden 2a bis 2d; 3a bis 3d von den Endabschnitten 6e, 6f ausgehend in entgegengesetzter Richtung sich bewegend gegen den Mittenabschnitt 6g des Webrotors hin eingetragen werden.1a, the weft feed devices 4a, 8a, 8b; 5a, 7a, 7b in each case on the front side of the weaving rotor 6 arranged such that the weft threads 2a to 2d; 3a to 3d starting from the end sections 6e, 6f in opposite direction moving against the Center section 6g of the weaving rotor are entered.
