Ferner ist am Ladenprofil 17 ein Zwischenprofil 21 mit Schrauben befestigt, an dem die erfindungsgemäßen Führungsmittel 23 befestigt worden sind. Diese Befestigung erfolgt mit Hilfe von Schrauben 22, die durch im Zwischenprofil 21 vorgesehene Schlitze reichen und die mit einem in den Führungsmitteln 23 vorgesehenem Gewinde zusammenarbeiten.The comb drawer 8 has a drawer axis 16 on which a Shop profile 17 has been fastened with screws. On the shop profile 17 the reed 9 with fastening means 18 attached. There is also an intermediate profile 21 on the shop profile 17 attached with screws to which the invention Guide means 23 have been attached. This attachment takes place with the help of screws 22, which are in the intermediate profile 21 slots provided and the one with cooperate with the guide means 23 provided thread.

Die Führungsmittel 23 dienen dabei zur Führung des Greiferbandes 1 und/oder eines Führungsteils 24 für den Greifer. Das Führungsteil 24 bildet eine Verbreiterung des Greiferbandes 1 und ist im Bereich sowohl des Gebergreifers 2 als auch des Nehmergreifers 3 vorgesehen. Diese Führungsmittel 23 können sich mit Hilfe der Bewegung der Kammlade 8 in und aus dem Webfach 15 bewegen. Die Führungsmittel 23 befinden sich, wie mit einer gestrichelten Linie in Fig. 2 dargestellt worden ist, in einer Stellung, bei der ein eingetragener Schußfaden an die Anschlaglinie 19 des Gewebes 20 angeschlagen wird. Wenn die Führungsmittel 23 durch die Kettfädenfläche 14 hindurch in das Webfach 15 eingetragen worden sind, bilden sie eine sich in Längsrichtung A des Webfaches 15 erstreckende Führung für das Greiferband 1 und/oder das Führungsteil 24.The guide means 23 serve to guide the gripper belt 1 and / or a guide part 24 for the gripper. The Guide part 24 forms a widening of the gripper belt 1 and is in the area of both the gripper 2 and the Slave gripper 3 provided. These guide means 23 can with the help of the movement of the comb drawer 8 in and out of the Move shed 15. The guide means 23 are located as has been shown with a dashed line in Fig. 2 is in a position where a registered weft is struck on the stop line 19 of the fabric 20. When the guide means 23 through the warp thread surface 14 have been entered into the shed 15 form they are in the longitudinal direction A of the shed 15 extending guide for the gripper belt 1 and / or Guide part 24.

Die erfindungsgemäßen Führungsmittel 23 weisen, wie mehr im einzelnen in den Fig. 3 und 4 dargestellt worden ist, ein erstes Führungselement 25 auf, das das Greiferband und/oder das Führungsteil 24 unterstützt sowie ein zweites Führungselement 26, das mit der Oberseite des Greiferbandes 1 und/ oder mit dem Führungsteil 24 für den Greifer 2 zusammenarbeitet. Das Oberteil 27 des ersten Führungselements 25 unterstützt das Führungsteil 24. Dieses Oberteil 27 weist eine abgerundete oder kegelförmige Form auf. Im Bereich des Oberteils 27 ist ebenfalls ein Führungsteil 28 vorgesehen, das sich parallel zum Greiferband 1 befindet und gestattet, das Greiferband 1 zwischen diesem Führungsteil 28 und der Führungsfläche 29 des zweiten Führungselements 26 zu führen. Das Führungsteil 28 kann - wie dargestellt - flach sein oder eine abgerundete oder eine zylinderförmige Form aufweisen. Die Führungsfläche 33 des Führungsteils 24 bildet mit dem Greiferband 1 einen Winkel D und wird geführt von und unterstützt über einen Teil der Länge des vorerwähnten Oberteils 27 des ersten Führungselements 25. In der dargestellten Ausführungsform wird das Führungsteil 24 nicht auf dem vorderen Ende 34 des Oberteils 27 des ersten Führungsteils 25 geführt. Das zweite Führungselement 26 weist ein Oberteil 30 auf, das, wie auch das Oberteil 27, eine abgerundete oder kegelförmige Form aufweist.The guide means 23 according to the invention, as more in 3 and 4 has been shown individually first guide element 25 on the gripper belt and / or the guide part 24 supports and a second guide element 26, which with the top of the gripper belt 1 and / or cooperates with the guide part 24 for the gripper 2. The upper part 27 of the first guide element 25 supports the guide part 24. This upper part 27 points a rounded or conical shape. In the area of Upper part 27 is also provided with a guide part 28, which is parallel to the gripper belt 1 and allows the gripper belt 1 between this guide member 28 and the Guide surface 29 of the second guide element 26 to guide. The guide part 28 can - as shown - be flat or have a rounded or a cylindrical shape. The guide surface 33 of the guide part 24 forms with the Gripper belt 1 an angle D and is guided by and supported over part of the length of the aforementioned top 27 of the first guide element 25. In the illustrated Embodiment, the guide member 24 is not on the front End 34 of the upper part 27 of the first guide part 25 guided. The second guide element 26 has an upper part 30 on, like the top 27, a rounded or has a conical shape.

Das Führungsteil 24 wird dabei auch seitlich zwischen einer Führungsfläche 31 des Führungselements 26 und einer Führungsfläche 32 des Führungselements 25 geführt. Ferner weist das erste Führungselement 25 eine Fläche 36 auf, die sich im Bereich des Führungsteils 24 in einer gewissen Entfernung der Unterfläche 37 des Führungsteils 24 befindet und als Notführungsfläche fungieren kann.The guide member 24 is also laterally between one Guide surface 31 of the guide element 26 and a guide surface 32 of the guide element 25 out. Furthermore, the first guide element 25 has a surface 36 which is in the Area of the guide member 24 at a certain distance from the Lower surface 37 of the guide part 24 is located and as an emergency guide surface can act.

Wird die Kammlade 8 aus der Anschlagposition in ihre hintere Stellung bewegt, so bewegen sich die Führungsmittel 23 gemäß Pfeil P. Während dieser Bewegung wird auch das Webfach 15 gebildet, das heißt, daß der Winkel zwischen den flachen Kettfäden 13 und 14 während dieser Bewegung vergrößert und zum Beispiel maximal wird, wenn sich die Kammlade 8 in der hinteren Stellung, wie dargestellt in Fig. 2, befindet. Dabei werden der Reihe nach Stellungen erhalten, wie sie mittels einer gestrichelten Linie und in einer vollen Linie in Fig. 2 dargestellt worden sind.The comb drawer 8 from the stop position to its rear Moved position, the guide means 23 move according to Arrow P. During this movement, the shed 15 is also formed, that is, the angle between the flat Warp threads 13 and 14 enlarged and during this movement for example becomes maximum when the comb tray 8 is in the rear position, as shown in Fig. 2, is. there positions are obtained in order as they are by means of a dashed line and a full line in FIG. 2 have been shown.

Das Oberteil 30 ist dabei in solcher Weise angeordnet, daß dieses Oberteil 30 über eine gewisse Länge nahezu parallel zur Kettfädenfläche 14 verläuft, wenn das Oberteil 30 des zweiten Führungselements 26 die Kettfädenfläche 14 gerade berührt und durch die Kettfädenfläche 14 hindurch passieren wird, um in das Webfach 15 einzutreten.The upper part 30 is arranged in such a way that this upper part 30 almost parallel over a certain length to the warp thread surface 14 when the upper part 30 of the second guide element 26, the warp thread surface 14 straight touched and pass through the warp thread surface 14 to enter the shed 15.

Das Oberteil 27 ist dabei in solcher Weise angeordnet, daß dieses Oberteil 27 über eine gewisse Länge nahezu parallel zur Kettfädenfläche 14 verläuft, wenn das Oberteil 27 des ersten Führungselements 25 die Kettfädenfläche 14 gerade berührt und durch die Kettfädenfläche 14 hindurch passieren wird, um in das Webfach 15 einzutreten.The upper part 27 is arranged in such a way that this upper part 27 almost parallel over a certain length to the warp thread surface 14 when the upper part 27 of the first guide element 25, the warp thread surface 14 straight touched and pass through the warp thread surface 14 to enter the shed 15.

Durch die Anordnung der Oberteile 27 und 30 können die Führungselemente 25 und 26 günstig durch die Kettfädenfläche 14 hindurch passieren. Bei Kettfäden, bei denen unterschiedliche dünne Fäden zu einem dickeren Faden gebildet worden sind, wird auch vermieden, daß die Führungselemente 25 und 26 dadurch zwischen die einzelnen Fäden geraten können, daß die Kettfäden jeweils auf einer Seite der Führungselemente 25 und 26 landen beziehungsweise vereinzelt darauf liegen bleiben.The arrangement of the upper parts 27 and 30 can Guide elements 25 and 26 favorably through the warp thread surface 14 pass through. For warp threads where different thin threads have been formed into a thicker thread are also avoided that the guide elements 25 and 26th can get caught between the individual threads that the Warp threads on one side of the guide elements 25 and 26 land or occasionally stay on it.

Die Länge, über die das Oberteil 27 nahezu parallel zur Kettfädenfläche 14 verläuft, ist vorzugsweise relativ groß und größer als die Länge, über die das Oberteil 30 parallel verläuft, weil die Gefahr eines Bruches und/oder von Beschädigungen von Kettfäden, die durch das Oberteil 27 entstehen, größer ist als die, welche durch das Oberteil 30 entstehen. Diese Gefahr ist größer, weil sich, einerseits, das Oberteil 27 dichter am Webblatt 9 befindet als das Oberteil 30 und in solcher Weise dieses Oberteil 27 weniger leicht zwischen die Kettfädenfläche 14 dringen kann, und andererseits, weil das Oberteil 27 mit dem Greiferband 1 und/oder mit dem Führungsteil 24 zusammenarbeitet und in solcher Weise dem Verschleiß unterliegt.The length over which the upper part 27 is almost parallel to the warp thread surface 14 runs, is preferably relatively large and greater than the length over which the upper part 30 runs parallel, because of the risk of breakage and / or damage of warp threads created by the upper part 27 is larger than that caused by the upper part 30. This danger is greater because, on the one hand, the top part 27 is closer to the reed 9 than the upper part 30 and in so this top 27 less easily between the Warp thread surface 14 can penetrate, and on the other hand, because that Upper part 27 with the gripper belt 1 and / or with the guide part 24 works together and wear in such a way subject.

Bei Greiferwebmaschinen ist es bekannt, ein Greiferband 1 mit einem nahezu rechtwinkligen Querschnitt so zentral und/oder so horizontal wie möglich durch das Webfach 15 zu führen. Um diese Bedingung zu erfüllen und zu gestatten, das Oberteil 27 parallel zur Kettfädenfläche 14 das Webfach betreten zu lassen, ist es erforderlich, das Greiferband 1 und das Oberteil 27, wie oben erwähnt, unter einem gewissen Winkel D zueinander anzuordnen. Um dies zu gestatten, weist das Führungsteil 24 eine Auskragung unter dem Greiferband 1 auf, die mit einer Führungsfläche 33 versehen ist, die einen Winkel zum Greiferband 1 bildet und mit dem Oberteil 27 des Führungselements 25 parallel verläuft. Der Winkel D ist dabei so beschaffen, daß der Abstand zwischen dem Greiferband 1 und dem Oberteil 27 des ersten Führungselements 25 in Richtung des vorderen Endes 34 des Führungselements 25 zunimmt.In rapier weaving machines it is known to have a rapier belt 1 an almost rectangular cross-section so central and / or to run as horizontally as possible through the shed 15. Around to meet this condition and to allow the upper part 27 enter the shed parallel to the warp thread surface 14 leave, it is necessary the gripper belt 1 and the upper part 27, as mentioned above, at a certain angle D to arrange each other. In order to allow this, this indicates Guide part 24 has a projection under the gripper belt 1, which is provided with a guide surface 33, the one Forms an angle to the gripper belt 1 and with the upper part 27 of the Guide element 25 runs parallel. The angle D is included so that the distance between the gripper belt 1 and the upper part 27 of the first guide element 25 in the direction of the front end 34 of the guide element 25 increases.

In dem dargestellten Beispiel weist das Oberteil 30 des Führungselements 26 einen Winkel E mit dem Greiferband 1 auf, der um einige Grad größer ist als der Winkel D, den das Oberteil 27 mit dem Greiferband bildet. Es leuchtet ein, daß diese Winkel D und E von der gegenseitigen Stellung des Webfaches 15, der Kammlade 8 und der Führungsmittel 23 abhängen.In the example shown, the upper part 30 of the guide element 26 an angle E with the gripper belt 1, which is a few degrees larger than the angle D that the Forms upper part 27 with the gripper belt. It is obvious that these angles D and E from the mutual position of the Shed 15, comb comb 8 and guide means 23 depend.

In den Fig. 3 und 4 ist ein Ausführungsbeispiel dargestellt, bei dem die einzelnen Führungsmittel 23 in solcher Weise zueinander angeordnet werden können, daß das erste Führungselement 25 von ersten Führungsmitteln 23 gerade unter einem zweiten Führungselement 26 folgender Führungsmittel 23 angeordnet ist. Um dies zu gestatten, weisen die Führungsmittel 23 zum Beispiel eine Form auf, wie in den Fig. 3 und 4 dargestellt worden ist, wobei die Führungselemente 25 und 26 räumlich getrennt zueinander angeordnet sind. Dies gestattet, mit einem einzigen Führungsmittelsatz 23, das erste und zweite Führungselement 25 und 26 in Längsrichtung A in einer gewissen Entfernung voneinander anzuordnen, als auch das erste und zweite Führungselement 25 und 26 in Längsrichtung A mit gleichem Abstand vorzusehen.3 and 4, an embodiment is shown in which the individual guide means 23 in such a way can be arranged to each other that the first guide element 25 of first guide means 23 just under one second guide element 26 following guide means 23 arranged is. In order to allow this, the guide means 23, for example, has a shape as shown in FIGS. 3 and 4 with the guide elements 25 and 26 are spatially separated from each other. This allows with a single set of guide means 23, the first and second guide element 25 and 26 in the longitudinal direction A in one some distance from each other, as well first and second guide elements 25 and 26 in the longitudinal direction A to be provided at the same distance.
