Definitions
- the invention relates to a shaft rod for building a webschaft for a loom.
- each heald In weaving looms are used to hold a large number of healds, each heald a thread eye for guiding a warp thread. Further warp threads run between the healds. By moving the heald up and down, the warp threads guided by the heddles can be moved out of the plane of the remaining warp threads, thereby creating a shed into which the weft thread can be inserted.
- Each weave usually has two mutually parallel horizontal shaft rods whose ends are interconnected by vertical side supports.
- the weave thus forms a rectangular frame.
- the upper and lower shafts each carry, e.g. made of steel Litzentragschiene.
- the healds have end loops, with which they are held on the Litzentragschienen.
- the healds and the Litzentragschienen are usually made separately and connected with each other afterwards. This suggests the DE 10 2004 037 717 B3 the use of rubber straps in front.
- the shaft rod is provided for this purpose with a groove into which a foot of the heddle support rail extends.
- the rubber cord To clamp the foot in the groove is the rubber cord, which is inserted into the remaining space in the axial stretched state. When the rubber cord relaxes, it shortens, increasing its diameter, so that it wedges the foot of the heddle guide into the groove of the shaft rod. However, this requires that the rubber cord can contract accordingly along its entire length.
- the heald bar is to be provided with a relatively complicated shaped accurately formed foot to cause a correct positioning of the rail and its positive locking.
- a shaft rod with a Litzentragschiene known which has a trapezoidal foot. This is made separately depending on the embodiment and riveted to the heald bar or formed integrally therewith.
- the shaft rod has a correspondingly shaped receiving space, in which the mounting rail foot is inserted and secured, for example, by adhesive, so that a thin adhesive joint is formed.
- a shaft rod is known, which is composed of narrow strip-shaped metal shells. At the lower edge of the shaft rod, a heddle support rail is attached. The connection can be secured by adhesive.
- the US-A-4,844,130 discloses a shaft rod with a heddle support rail having a receiving groove for a lower edge of the shaft rod. Adhesive is used for the connection.
- the shaft rod according to the invention has a rod body and a Litzentragschiene, which are glued together.
- the bond is produced within a receiving space in which a holding portion and a space-filling solidifying material, e.g. are arranged in the form of an adhesive.
- the heddle support rail is designed as a sheet metal bent part with at least one bending edge. Under "sheet metal part” are also understood profiled sheet metal parts. They consist of sheet preferably uniform thickness.
- the space-filling adhesive fills the receiving space at least largely, in which extends the holding portion.
- the space filling adhesive occupies the larger part of the receiving space while the holding portion occupies the smaller part of the receiving space.
- the holding section engages with a large clearance in the receiving space, so that it can always be introduced into the receiving space in a simple manner, regardless of manufacturing tolerances.
- the receiving space in the region of its mouth has a cross-sectional width both in the opening direction and in the transverse direction of the mouth, which is greater than the material thickness of the holding portion.
- the room-filling adhesive compensates for manufacturing tolerances and secures the holding section materially in the receiving space. This results in a low-cost connection.
- the holding section and the receiving space interlock.
- additional connecting means such as e.g. Rivets or screws superfluous.
- the compound is mixed cohesively and positively, i. it is based in part on the material connection between the receiving space, holding portion and adhesive and partly on the shape of the parts involved, which abut against each other at at least one point, preferably at least two surfaces.
- the holding portion is preferably a part of the heddle support rail, but may also be part of the rod body. It is preferably designed as a foot with a uniform material thickness. Preferably, the holding portion is a part of a sheet metal bending part, which forms the heddle rack or the rod body. For anchoring in the receiving space of the holding portion is angled in a connection state in the receiving space located location. This improves the anchoring of the holding portion in the receiving space.
- the receiving space is preferably formed on the rod body.
- the rod body may be formed as an aluminum extruded profile. It may also be formed by a sheet metal bent part or several components connected to one another by welding, gluing or other joining technologies.
- the arrangement of the receiving space on the rod body leads to simple designs of the heddle support rail, which can then be designed as a sheet metal bent part particularly simple. Preferably, a height-width ratio of ⁇ 5 on. This creates a compact, rigid mounting rail.
- the support rail may have other bending edges in addition to the at least one bending edge, whereby a stable solid support rail is formed. The bends form stiffeners of the metal strip from which the mounting rail.
- the heald support rail and the rod body are preferably screwed into each other for mounting, i. the holding section is pivoted into the receiving space.
- the angled foot portion preferably has a greater width than the mouth of the receiving space. Thus, the foot portion engages in a retracted state, a wall of the receiving space, which causes a positive locking.
- the mounting by means of pivotal or rotary movement of the rod body and the shaft support rail to each other facilitates the installation of a long support rail of a shaft rod, for example, of a length of 4 to 6 meters.
- the space-filling adhesive can be introduced into the receiving space before merging the support rail and rod body. After swiveling in the mounting rail, the adhesive flows around the retaining section and locks it. Depending on the composition of the adhesive, it is also possible to remove it after assembly, i. after the pivoting of the mounting rail in the receiving space of the rod body to introduce into the receiving space. A preferably low-viscosity adhesive then almost completely fills the receiving space.
- At least two surfaces of the connecting portion that are at an angle to one another are preferably in contact with surfaces of the receiving space and thus fix the position of the holding portion and the receiving space in conjunction with one another, so that the heddle support rail is fixed in a desired setpoint position during curing of the adhesive . It is also possible to provide locking means on the connecting device, which lead to a latching effect and secure the heald rail temporarily. This simplifies the fixation of the heddle support rail during the curing of the adhesive.
- the receiving space can be arranged both on the heddle support rail and on the rod body. In the latter case, it is preferably provided on a flat side thereof. It can also be provided on a narrow side, if desired.
- the receiving space has an orifice which opens parallel or perpendicular to a flat side of the heddle support rail. Below the mouth, a trough-like region is preferably provided, which forms the receiving space and can be introduced into the larger amounts of adhesive before the heddle support rail is connected to the rod body.
- the shaft rod 1 has a rod body 2 and a Litzentragschiene 3, which are interconnected.
- the rod body 2 may extend over several meters in length. It provides the required vertical stiffness of the shaft rod 1.
- it is formed by an extruded aluminum profile having one or more chambers in the form of cavities.
- the rod body 2 has a web portion 4 extending vertically away from the chamber profile, on which the heddle support rail 3 is mounted.
- the rod body 2 may alternatively also be an otherwise formed body.
- it may be constructed of one or more parts joined together by appropriate bonding technology such as gluing, welding and the like. It can thus be composed of sheet metal parts, non-ferrous metals, plastic parts and similar elements.
- the heddle support rail 3 is preferably a bent sheet metal part. It is used for the storage of healds, of which in FIG. 1 a heddle 5 is representative of a large number of healds is illustrated, which are held with their end eyelets 6 each on the heddle support rail 3.
- the heddle support rail 3 is connected by a connecting device 7 with the rod body 2.
- the heddle support rail 3 has a substantially uniform sheet metal thickness, ie material thickness, as the sheet metal bent part. It is provided at its upper end with a bending edge 8 to form a rounded support surface for the end eyelet 6 of the heald 5. Starting from the bending edge 8, a long leg extends to a further bending edge 9 at the heald support rail 3 is preferably angled at right angles. At the bending edge 9 begins a holding portion 10 for anchoring the heddle support rail 3 on the rod body 2.
- the holding portion 10 is formed in the present embodiment by a hook-shaped portion with two bending edges 11, 12 and a clear width Lw. Thus, the holding portion 10 defines a hook profile 13 with U-section.
- To the connecting device 7 also includes a receiving space 14 which is bounded by a projecting from the web 4 wall portion 15.
- the wall portion 15 initially extends at an approximately right angle to the web 4 and then extends with a front wall portion 16 parallel to the web 4.
- the upper edge 34 of the front wall portion 16 is in turn bent inwardly.
- the front wall portion 16 forms a hook profile 43, which is opposite to the hook profile 13 of the holding portion 10.
- the receiving space 14 has a slot-like mouth 17, which opens approximately parallel to the web 14 upwards. It can be provided in the immediate vicinity of the mouth 17 at the web portion 4, a rib 18 which extends parallel to the mouth 17.
- the holding portion 10 has a cross section which is substantially smaller than the total cross section of the receiving space 14.
- the trough-like receiving space 14 serves to receive space-filling adhesive 19, as is apparent from the FIGS. 2b and 2c evident.
- adhesive is meant here any substance which is initially in a liquid, viscous or pasty, kneadable or otherwise easily moldable state and is curable, wherein it does not reduce its volume during curing or at least not substantially. That means he stays full of space.
- the curing can be done by chemical additives, physical action, such as heat, light or the like, or by passage of time.
- the adhesive preferably bonds to the surfaces wetted by it.
- it can be rigid or slightly elastic after hardening. In the latter case, it may be resilient or have an inner damping, which acts in particular vibration damping.
- FIG. 2b illustrates, first, a surface which is below the mouth 17, preferably below the upper edge 34 of the receiving space 14. It is now the heald bar 3 in the in FIG. 2b illustrated position approximately at right angles from the web portion 4 standing away with her Verbindurigsabterrorism 10 attached to the front wall portion 16.
- the angled upper edge 34 of the front wall portion 16 is preferably slightly shorter than the inside width Lw of the hook profile 13, so that it can be pushed from top to bottom over the angled upper edge 34 of the front wall portion 16.
- the Litzentragschiene 3 is then pivoted, as in FIG. 2b an arrow 20 indicates.
- the heald support rail 3 eventually retracts to its position Figure 2c pivoted in which it extends substantially parallel to the web portion 4. It rests with at least two outer surfaces of its connecting portion 10 on corresponding inner surfaces of the receiving space 14.
- the corresponding area plants are in Figure 2c denoted by 22 and 23.
- the bending edge 11 preferably sits under the rib 18 while the heddle support rail 3 can be seated on the inwardly bent upper edge 34 of the front wall portion 16 as needed. Then, two surfaces may abut each other with an inner surface of the connecting portion 10 abutting an outer surface of the upper edge 34 of the front wall portion 16.
- the area plant 35 is created.
- the rod body 2 may be formed by or include a sheet metal bent part, which in particular forms the web section 4.
- An example of this is in FIG. 3 specified. It eliminates the rib 18, otherwise the above description applies based on the same reference numerals.
- FIG. 4a shows a heddle support rail 3 whose retaining section 10 is merely angled. It lacks in comparison to the embodiment of FIGS. 2 and 3 the bending edge 12.
- the in FIG. 4a noted height H and there also noted width B behave as 5: 1 or less.
- the heddle support rail 3 is particularly compact and stiff.
- This has on its side remote from the front wall portion 16 side an inclined surface 24, the angular orientation is oriented parallel to the part 25 of the holding portion 10.
- the part 25 is arranged at the end of the holding part 10.
- This Litzentragschiene 3 can, as Figure 4c illustrated, are inserted into the filled with adhesive 19 receiving space 14. A rotary or a pivoting movement, like her FIG. 2b is not required here.
- the anchoring of the Litzentragschiene 3 on the rod body 2 is carried out here preferably mainly cohesively.
- the positive connection, in particular in the vertical direction, is like he at FIGS. 2 and 3 is missing, missing here.
- the advantage lies in a particularly low height.
- the distance S between the upper part 26 of the holding portion 10 and the lower part 27 of the front wall portion 16 may be less than 4 mm as it is FIG. 4d illustrated. Otherwise, the previous description applies based on the introduced reference numerals accordingly. Is the heddle support rail 3 with the rod body 2 according to FIG. 4d connected, the alignment of the heddle support rail 3 to the rod body 2 by the surface systems 22, 35 can be carried out.
- FIGS. 5a to 5c can illustrate, using the rod body 2 after FIG. 4b also a Litzentragschiene 3 are used, which has a further bending edge 28 both on its upper side, the bending edge 8 and on its underside.
- the heddle support rail 3 is formed as a sheet metal bent part, for example in the form of a rolled section or Rollformprofils.
- One of the legs 8 extending away from the bending edge 8 is formed at its outer end as a holding portion 10. This one can, like FIG. 5a illustrated already in FIG. 4a shown and described form or alternatively the shape according to FIG. 2a exhibit.
- FIG. 5b illustrates the heddle support rail 3 for connection to the rod body 2 initially attached to the mouth 17 of the receiving space 14, that the front wall of the Litzentragschiene 3 rests with its back 37 flat on the front wall portion 16.
- the lower edge of the part 25 of the holding portion 10 abuts against the inwardly directed upper edge 34 of the front wall portion 16.
- the heddle support rail 3 must deform slightly elastically when it is pressed down. This gives a latching effect with which the part 25 snaps over the inwardly facing upper edge 34 of the front wall section 16.
- the heddle support rail 3 is initially provisionally secured to the rod body 2.
- Part 25 of the holding portion 10 displaces a portion of the adhesive 19.
- the receiving space 14 is filled completely with adhesive 19. This condition is in FIG. 5c illustrated.
- a further surface installation 36 can be created in that the rear side 37 of the front wall of the heddle support rail bears against the outside of the front wall section 16.
- FIG. 6 shows that in the FIGS. 5a to 5c illustrated principle are also applied to shaft rods 1, the rod body 2 is formed by a sheet metal part.
- the above description applies on the basis of corresponding reference numerals.
- a further modified embodiment is in the FIGS. 7a to 7c played.
- This is based on the arrangement of the receiving space 14 on the Litzentragschiene 3, which is designed as a sheet metal bent part.
- the holding portion 10 is formed as a cross-sectional hook-shaped strip on the web portion 4 and thus on the rod body 2.
- Laying down the receiving space 14 of the lower bending edge 28 outgoing rear leg of the Litzentragschiene 3 is bent in the direction of the web portion 4 toward two mutually parallel bending edges 29, 30, so that a parallel to the rest of Litzentragschiene 3 part 31 with another part 32nd the mouth 17 limited.
- the other part 32 is formed by a bent to the web portion 4 edge of a leg of the Litzentragschiene 3, which extends away from the upper bending edge 8 down.
- the mouth 17 is approximately perpendicular to the web section 4.
- At the web portion 4 of the holding portion 10 is formed as a hook-shaped in cross-section bar, which may be assigned as needed a spaced parallel rib 33 arranged.
- the assembly of the rod body 2 with the Litzentragschiene 3 takes place as from the FIGS. 7b and 7c seen.
- adhesive 19 is arranged in the receiving space 14 .
- the Litzentragschiene 3 and the rod body 2 are hooked into each other and pivoted toward each other until the state after FIG. 7c is reached.
- the adhesive 19 fills all between the shaft support rail 3 and the rod body 2 existing cavities and gaps completely.
- This principle is also applicable when the web portion 4 of the rod body 2 is formed by a bent sheet metal part, as it FIG. 8 illustrated. Again, the previous applies Description based on the already introduced reference numerals accordingly.

Description
Die Erfindung betrifft einen Schaftstab zum Aufbau eines webschafts für eine Webmaschine.The invention relates to a shaft rod for building a webschaft for a loom.
In Webmaschinen dienen Webschäfte zur Aufnahme einer großen Anzahl von Weblitzen, wobei jede Weblitze ein Fadenauge zur Führung eines Kettfadens aufweist. Weitere Kettfäden verlaufen zwischen den Weblitzen. Durch eine Auf- und Abbewegung des Webschafts können die von den Litzen geführten Kettfäden aus der Ebene der übrigen Kettfäden heraus bewegt werden, wodurch ein Fach entsteht, in das der Schussfaden eingetragen werden kann.In weaving looms are used to hold a large number of healds, each heald a thread eye for guiding a warp thread. Further warp threads run between the healds. By moving the heald up and down, the warp threads guided by the heddles can be moved out of the plane of the remaining warp threads, thereby creating a shed into which the weft thread can be inserted.
Jeder Webschaft weist meist zwei zueinander parallele horizontale Schaftstäbe auf, deren Enden untereinander durch vertikale Seitenstützen verbunden sind. Der Webschaft bildet somit einen rechteckigen Rahmen. Der obere und der untere Schafstab tragen jeweils eine z.B. aus Stahl bestehende Litzentragschiene. Die Weblitzen weisen Endösen auf, mit denen sie auf den Litzentragschienen gehalten werden.Each weave usually has two mutually parallel horizontal shaft rods whose ends are interconnected by vertical side supports. The weave thus forms a rectangular frame. The upper and lower shafts each carry, e.g. made of steel Litzentragschiene. The healds have end loops, with which they are held on the Litzentragschienen.
Die Webschäfte und die Litzentragschienen werden meist getrennt gefertigt und im Nachhinein miteinander verbunden. Dazu schlägt die
Zum Festklemmen des Fußes in der Nut dient die Gummischnur, die in den verbleibenden Raum in axial gerecktem Zustand eingeführt wird. Wird die Gummischnur entspannt, verkürzt sie sich, wobei ihr Durchmesser zunimmt, so dass sie den Fuß der Litzentragschiene in der Nut des Schaftstabs festkeilt. Dazu ist allerdings erforderlich, dass sich die Gummischnur auf ganzer Länge entsprechend zusammenziehen kann. Außerdem ist die Litzentragschiene mit einem relativ kompliziert geformten passgenau ausgebildeten Fuß zu versehen, um eine korrekte Positionierung der Schiene und deren auch formschlüssige Sicherung zu bewirken.To clamp the foot in the groove is the rubber cord, which is inserted into the remaining space in the axial stretched state. When the rubber cord relaxes, it shortens, increasing its diameter, so that it wedges the foot of the heddle guide into the groove of the shaft rod. However, this requires that the rubber cord can contract accordingly along its entire length. In addition, the heald bar is to be provided with a relatively complicated shaped accurately formed foot to cause a correct positioning of the rail and its positive locking.

Diese Art der Verbindungstechnik setzt eine enge Tolerierung der miteinander zu verbindenden Teile voraus.This type of connection technology requires a close tolerance of the parts to be joined together.
Davon ausgehend ist es Aufgabe der Erfindung, eine Möglichkeit zu schaffen, mit der sich Schaftstäbe für Webschäfte auf einfache Weise prozesssicher herstellen lassen.On this basis, it is an object of the invention to provide a way with which shaft rods for heddle shafts can be produced process reliable in a simple manner.
Diese Aufgabe wird mit dem Schaftstab nach Anspruch 1 gelöst:This object is achieved with the shaft rod according to claim 1:
Der erfindungsgemäße Schaftstab weist einen Stabkörper und eine Litzentragschiene auf, die miteinander verklebt sind. Die Verklebung wird innerhalb eines Aufnahmeraums erzeugt, in dem ein Halteabschnitt sowie ein raumfüllendes sich verfestigendes Material z.B. in Form eines Klebstoffs angeordnet sind. Die Litzentragschiene ist als Blechbiegeteil mit wenigstens einer Biegekante ausgebildet. Unter "Blechbiegeteil" werden auch walzprofilierte Blechteile verstanden. Sie bestehen aus Blech vorzugsweise einheitlicher Dicke.The shaft rod according to the invention has a rod body and a Litzentragschiene, which are glued together. The bond is produced within a receiving space in which a holding portion and a space-filling solidifying material, e.g. are arranged in the form of an adhesive. The heddle support rail is designed as a sheet metal bent part with at least one bending edge. Under "sheet metal part" are also understood profiled sheet metal parts. They consist of sheet preferably uniform thickness.
Diese Maßnahmen gestatten eine besonders einfache und prozesssichere Herstellung des Schaftstabs. Der raumfüllende Klebstoff füllt den Aufnahmeraum zumindest weitgehend aus, in den sich der Halteabschnitt erstreckt. Vorzugsweise nimmt der raumfüllende Klebstoff den größeren Teil des Aufnahmeraums ein während der Halteabschnitt den geringeren Teil des Aufnahmeraums einnimmt. Mit anderen Worten, der Halteabschnitt greift mit einem großen Spiel in den Aufnahmeraum, so dass er unabhängig von Fertigungstoleranzen immer auf einfache Weise in den Aufnahmeraum eingeführt werden kann. Dazu weist der Aufnahmeraum im Bereich seiner Mündung eine Querschnittsweite sowohl in Öffnungsrichtung wie auch in Querrichtung der Mündung auf, die größer als die Materialdicke des Halteabschnitts ist. Der raumfüllende Klebstoff gleicht Fertigungstoleranzen aus und sichert den Halteabschnitt stoffschlüssig in dem Aufnahmeraum. Dies ergibt eine kostengünstige Verbindung.These measures allow a particularly simple and reliable production of the shaft rod. The space-filling adhesive fills the receiving space at least largely, in which extends the holding portion. Preferably, the space filling adhesive occupies the larger part of the receiving space while the holding portion occupies the smaller part of the receiving space. In other words, the holding section engages with a large clearance in the receiving space, so that it can always be introduced into the receiving space in a simple manner, regardless of manufacturing tolerances. For this purpose, the receiving space in the region of its mouth has a cross-sectional width both in the opening direction and in the transverse direction of the mouth, which is greater than the material thickness of the holding portion. The room-filling adhesive compensates for manufacturing tolerances and secures the holding section materially in the receiving space. This results in a low-cost connection.
Der Halteabschnitt und der Aufnahmeraum greifen ineinander. Durch die Formgebung der ineinander greifenden Bereiche werden zusätzliche Verbindungsmittel, wie z.B. Niete oder Schrauben überflüssig. Die Verbindung ist gemischt stoffschlüssig und formschlüssig, d.h. sie beruht teilweise auf der stofflichen Verbindung zwischen Aufnahmeraum, Halteabschnitt und Klebstoff und teilweise auf der Formgebung der beteiligten Teile, die an zumindest einer Stelle, vorzugsweise an zumindest zwei Flächen aneinander anliegen.The holding section and the receiving space interlock. By shaping the interlocking regions, additional connecting means, such as e.g. Rivets or screws superfluous. The compound is mixed cohesively and positively, i. it is based in part on the material connection between the receiving space, holding portion and adhesive and partly on the shape of the parts involved, which abut against each other at at least one point, preferably at least two surfaces.
Der Halteabschnitt ist vorzugsweise ein Teil der Litzentragschiene, kann aber auch Teil des Stabkörpers sein. Er ist vorzugsweise als Fuß mit einheitlicher Materialdicke ausgebildet. Vorzugsweise ist der Halteabschnitt ein Teil eines Blechbiegeteils, das die Litzentragschiene oder auch den Stabkörper bildet. Zur Verankerung in dem Aufnahmeraum ist der Halteabschnitt an einer in Verbindungszustand in dem Aufnahmeraum befindlichen Stelle abgewinkelt. Dies verbessert die Verankerung des Halteabschnitts in dem Aufnahmeraum.The holding portion is preferably a part of the heddle support rail, but may also be part of the rod body. It is preferably designed as a foot with a uniform material thickness. Preferably, the holding portion is a part of a sheet metal bending part, which forms the heddle rack or the rod body. For anchoring in the receiving space of the holding portion is angled in a connection state in the receiving space located location. This improves the anchoring of the holding portion in the receiving space.
Der Aufnahmeraum ist vorzugsweise an dem Stabkörper ausgebildet. Dazu kann der Stabkörper als Aluminiumstrangpressprofil ausgebildet sein. Er kann auch durch ein Blechbiegeteil oder mehrere untereinander durch Schweißen, Kleben oder andere Verbindungstechnologien verbundene Bauteile gebildet sein. Die Anordnung des Aufnahmeraums an dem Stabkörper führt zu einfachen Bauformen der Litzentragschiene, die als Blechbiegeteil dann besonders einfach gestaltet werden kann. Vorzugsweise weist ein Höhen-Breiten-Verhältnis von < 5 auf. Dadurch entsteht eine kompakte, steife Tragschiene. Die Tragschiene kann außer der mindestens einen Biegekante weitere Biegekanten aufweisen, wodurch eine stabile feste Tragschiene entsteht. Die Abkantungen bilden Versteifungen des Blechstreifens aus dem die Tragschiene besteht.The receiving space is preferably formed on the rod body. For this purpose, the rod body may be formed as an aluminum extruded profile. It may also be formed by a sheet metal bent part or several components connected to one another by welding, gluing or other joining technologies. The arrangement of the receiving space on the rod body leads to simple designs of the heddle support rail, which can then be designed as a sheet metal bent part particularly simple. Preferably, a height-width ratio of <5 on. This creates a compact, rigid mounting rail. The support rail may have other bending edges in addition to the at least one bending edge, whereby a stable solid support rail is formed. The bends form stiffeners of the metal strip from which the mounting rail.
Die Litzentragschiene und der Stabkörper werden zur Montage vorzugsweise in einander eingedreht, d.h. der Halteabschnitt wird in den Aufnahmeraum eingeschwenkt. Der abgewinkelte Fußabschnitt hat vorzugsweise eine größere Breite als die Mündung des Aufnahmeraums. Somit hintergreift der Fußabschnitt in eingedrehtem Zustand eine Wand des Aufnahmeraums, was eine formschlüssige Sicherung bewirkt.The heald support rail and the rod body are preferably screwed into each other for mounting, i. the holding section is pivoted into the receiving space. The angled foot portion preferably has a greater width than the mouth of the receiving space. Thus, the foot portion engages in a retracted state, a wall of the receiving space, which causes a positive locking.
Das Montieren mittels Schwenk- oder Drehbewegung des Stabkörpers und der Litzentragschiene zueinander erleichtert die Montage einer langen Tragschiene eines Schaftstabs, beispielsweise von einer Länge von 4 bis 6 Metern. Der raumfüllende Klebstoff kann vor dem Zusammenführen von Tragschiene und Stabkörper in den Aufnahmeraum eingebracht werden. Nach dem Einschwenken der Tragschiene umfließt der Klebstoff den Halteabschnitt und arretiert ihn. Abhängig von der Zusammensetzung des Klebstoffs ist es auch möglich, diesen nach der Montage, d.h. nach dem Einschwenken der Tragschiene in den Aufnahmeraum des Stabkörpers, in den Aufnahmeraum einzubringen. Ein vorzugsweise dünnflüssiger Klebstoff füllt dann den Aufnahmeraum nahezu vollständig aus. Nach dem Einschwenken der Tragschiene liegen vorzugsweise zumindest zwei zueinander in einem Winkel stehende Flächen des Verbindungsabschnitts an Flächen des Aufnahmeraums an und fixieren somit die Lage des Halteabschnitts und des Aufnahmeraums in Verbindung aufeinander, so dass die Litzentragschiene beim Aushärten des Klebstoffs in einer gewünschten Sollposition fixiert wird. Es ist auch möglich, an der Verbindungseinrichtung Rastmittel vorzusehen, die zu einem Rasteffekt führen und die Litzentragschiene temporär sichern. Dies vereinfacht die Fixierung der Litzentragschiene während der Aushärtung des Klebstoffs.The mounting by means of pivotal or rotary movement of the rod body and the shaft support rail to each other facilitates the installation of a long support rail of a shaft rod, for example, of a length of 4 to 6 meters. The space-filling adhesive can be introduced into the receiving space before merging the support rail and rod body. After swiveling in the mounting rail, the adhesive flows around the retaining section and locks it. Depending on the composition of the adhesive, it is also possible to remove it after assembly, i. after the pivoting of the mounting rail in the receiving space of the rod body to introduce into the receiving space. A preferably low-viscosity adhesive then almost completely fills the receiving space. After swiveling in of the mounting rail, at least two surfaces of the connecting portion that are at an angle to one another are preferably in contact with surfaces of the receiving space and thus fix the position of the holding portion and the receiving space in conjunction with one another, so that the heddle support rail is fixed in a desired setpoint position during curing of the adhesive , It is also possible to provide locking means on the connecting device, which lead to a latching effect and secure the heald rail temporarily. This simplifies the fixation of the heddle support rail during the curing of the adhesive.
Der Aufnahmeraum kann sowohl an der Litzentragschiene als auch an dem Stabkörper angeordnet sein. In letzterem Fall ist er vorzugsweise an einer Flachseite desselben vorgesehen. Er kann auch an einer Schmalseite vorgesehen werden, wenn dies gewünscht wird. Vorzugsweise weist der Aufnahmeraum eine Mündung auf, die sich parallel oder senkrecht zu einer Flachseite der Litzentragschiene öffnet. Unterhalb der Mündung ist vorzugsweise ein wannenartiger Bereich vorgesehen, der den Aufnahmeraum bildet und in den größere Klebstoffmengen eingebracht werden können, bevor die Litzentragschiene mit dem Stabkörper verbunden wird.The receiving space can be arranged both on the heddle support rail and on the rod body. In the latter case, it is preferably provided on a flat side thereof. It can also be provided on a narrow side, if desired. Preferably, the receiving space has an orifice which opens parallel or perpendicular to a flat side of the heddle support rail. Below the mouth, a trough-like region is preferably provided, which forms the receiving space and can be introduced into the larger amounts of adhesive before the heddle support rail is connected to the rod body.
