Definitions
- the invention relates to a heald with a shaft rod, which is constructed of a fiber-reinforced plastic material.
- the invention relates to the connection between the side supports of the heald and the shaft rods.
- Heald frames are generally rectangular frame-shaped structures with long horizontally disposed shaft rods and vertical side supports which interconnect the shaft rods at their respective ends.
- the shaft rods carry Litzentragschienen for holding healds.
- the basic structure of such a weaving can, for example.
- the DE 101 16 813 B4 or even the EP 0 531 886 A1 , of the EP 0 659 178 B2 or the EP 1 985 733 A1 be removed.
- the heald must be disassembled.
- the side supports are connected by suitable corner connectors with the shaft rods.
- the corner connectors are usually designed as clamping and or clamping devices. These are used to initiate the longitudinal forces of the side supports in the shaft rods so that they take no damage.
- the EP 0 513 281 B1 proposes to attach to the end of the shaft rod two metal plates, between which blocks are firmly attached.
- the sheet metal plates and the blocks define a cavity into which a projection of the side support fits.
- One of the blocks is with a threaded hole provided, in which a clamping screw can be screwed. This presses the projection of the side support against the opposite block and thus clamps the corner connector firmly.
- the DE 198 16 950 A1 discloses a heald frame referred to as a shaft frame, whose shaft bars are made of aluminum profile or composite material. At its end a cross-sectionally U-shaped sleeve member is mounted, the legs of which overlap the flat sides of the shaft rod. The sleeve member receives mounting screws for connecting an extension of the side support.
- the DE 101 16 813 B4 discloses a heddle with a corner joint that utilizes the elasticity of the heddle. This has a longitudinal slot which extends from a trained in the end of the heald bag over a certain distance along the shaft rod.
- the shaft rod also contains two clamping blocks, referred to as guide elements, which are inserted into a cavity of the shaft rod and fixedly connected to the side walls. A clamping screw can pull the two clamping blocks against each other. They clamp between each other an extension of the side support.
- the longitudinal slot provided in the shaft rod allows very little movement of the clamping blocks to clamp or release the extension of the side support.
- the corner joint works according to CH 427688 A , Again, a mounted at the end of the shaft rod longitudinal slot is used to allow a clamping movement of the above or below the slot leg of the shaft rod.
- a socket On the shaft rod a socket is attached, which has two flat body. These are glued to sections, preferably end portions of the two side surfaces or connected in a planar manner in other suitable manner.
- the flat bodies may be, for example, sheet metal plates, plastic plates or the like. They can have a uniform thickness or varying thicknesses.
- the flat bodies may taper away from the end of the shaft rod towards the center. This can contribute to the forces acting on the corner connector over a large area and without local To transfer jumps on the shaft rod.
- An alternative embodiment comes with only a flat body.
- the flat body is glued on both sides in a plane-parallel to the flat sides of the shaft rod slot in the shaft rod.
- first rigid stop element and a second, on the first stop element towards further tensionable stop element are arranged.
- a tensioning means can tension the second stop element against the first stop element.
- a pocket is formed by a corresponding recess of the shaft rod.
- an extension extending from the side support extending between the two stop elements can be tightened to form a firm connection between the shaft post and the side support.
- the first stop is rigid and the second stop resiliently mounted or resiliently, pivotally or otherwise mounted at least slightly movable, on the one hand a secure clamping of the extension of the side support and thus secure attachment as on the other hand given a rigid coupling between side support and shaft rod when the connection is tightened.
- the first stop element and the second stop element are preferably arranged independently of one another on the flat bodies.
- the first stopper member and the second stopper member may be a functional portion of a one-piece insert disposed between the flat bodies.
- the extension of the side support may be provided with a threaded bore into which a bolt engages extending through the first stop member.
- the first stop element preferably lies on the side of the extension pointing away from the side support.
- the invention combines several advantages. It offers a concept for the safe connection of side supports to shaft rods made of lightweight construction materials, which can be quite sensitive to the local application of force.
- lightweight construction bars may, for example, be formed from fiber-reinforced plastics as a solid body or as a hollow body. They may also be formed of light metal, in particular aluminum and / or magnesium alloys, e.g. in the form of correspondingly thin sheets, between which foam body, honeycomb body or the like can be kept for reinforcement. It may also be shaft rods made of light metal as a solid body or as a hollow body.
- the corner connector according to the invention can be applied to shaft rods of all the above and similar types.
- One of the stop elements serves to produce a rigid force transmission path between the side supports and the flat parts while the other stop element serves as a tensioning means.
- the heald has at least partially planar side surfaces.
- the flat bodies are arranged on flat parts of the side surfaces.
- the shaft rod has at least one non-planar side surface, it is also possible to adapt the flat body to the corresponding non-planar side surface by providing it with a corresponding complementary shape.
- the two side surfaces of the shaft rod are oriented parallel to each other.
- the shaft rod has preferably a rectangular cross-section. Other cross sections are possible.
- the flat bodies can be as mentioned metal plates.
- they may be steel plates, aluminum plates, sheet metal elements or the like. They preferably extend from one narrow side of the shaft rod to its other. So a large force application is achieved.
- the metal plates or sheets can be integrally connected to the shaft rod, preferably glued.
- the flat bodies are provided on the adhesive side facing the shaft rod with at least one preferably a plurality of projections, for example strips, knobs or the like, the height of which determines the thickness of an adhesive joint to be formed.
- the flat body may, if necessary, extend slightly over the narrow sides of the shaft rod. However, this is not necessary. Preferably, they release at least one narrow side of the shaft rod.
- Both stop elements preferably have different lengths.
- the rigidly arranged stop element preferably projects farther out of the end face of the shaft rod than the other stop element serving for clamping.
- both stop elements project beyond the flat body.
- the rigid stop element can be used in particular for the transmission of thrust forces which are to be transmitted from the side support to the shaft rod.
- the longer rigid stop member engages over at least a portion of the cross section of the side support.
- the first stop element is preferably rigidly connected to the flat bodies, for example by gluing or welding. It can be provided for this purpose individual welds or welds, for example. Laser welds. Also, between the flat body and the stop element, a mechanical connection can be provided by one or more rivets, one or more screws or other form-locking fastening means.
- the second stop element is slightly movable on at least one end. This mobility can be achieved by the stop element is movably connected to the flat body. These screws, rivets or the like can be used. It is also possible to weld an inner end of the stop element with one or both flat bodies. This can be done with one or more welds or welds. The extending away from the weld part of the stop element has inherently a certain resilience, which can be used to achieve the desired low mobility. In addition, the stopper element may have a recess at one or more locations in order to be able to spring better.
- the heald may be reduced to a shaft bar and one or two side supports.
- Such designs are e.g. applicable to heald frames, which have a fixed part of the loom associated lower part and removable from the loom upper part.
- Also for such reduced heddle shafts apply all variants described above.
- the heald is a complete rectangular frame with two shaft rods and two side supports.
- a heald 10 which belongs to a weaving machine not further illustrated. It forms a rectangular frame in which individual healds 11 are arranged. These are used to guide not further illustrated warp threads during the weaving process.
- the healds 11 are arranged on Litzentragschienen 12, 13, which are arranged horizontally at a vertical distance.
- the upper Litzentragschiene 12 is held on an upper shaft rod 14.
- the lower Litzentragschiene 13 is held on a lower shaft rod 15.
- the upper and lower shaft rods 14, 15 are each made of a suitable lightweight material, such as fiber-reinforced plastic, thin honeycomb-reinforced sheet, a thin-walled aluminum extrusion profile or the like.
- corner connectors are provided, of which in Fig. 1 the upper left is highlighted by a dashed circle.
- the following explanation of the highlighted here corner joint 20 applies mutatis mutandis to the three remaining other corner joints as well as corner joints of heddles, for example, have only one shaft rod and one or two side supports.
- Fig. 2 illustrates the corner joint 20 between the shaft bar 14 and the side support 16 by way of example.
- the shaft rod 14 here consists for example of a fiber-reinforced Plastic material in solid profile design with a slim, rectangular cross-section. Accordingly, it has an upper narrow side 21, a lower narrow side 22 and two preferably, but not necessarily, flat flat sides 23, 24 (FIG. Fig. 5 ). While the narrow sides 21, 22 are horizontal in use, the flat sides 23, 24 are vertically disposed in use.
- the cross section of the shaft rod 14 may be homogeneous. However, it can also be provided adjacent to the upper and / or the lower narrow side 21 or 22 with a reinforcing profile, for example a metal hollow profile, a plastic bar profile or other.
- the frame 25 includes a rear flat body 26 and a front flat body 27, which are each firmly connected to the flat sides 23, 24.
- the flat body 26, 27 may be formed in the simplest case by metal plates or other plate-shaped, for example made of plastic elements. However, the flat bodies 26, 27 are preferably made of a different material or a different material composition than the shaft rod 14. For example, the flat bodies 26, 27 may be made of aluminum or steel.
- the flat bodies 26, 27 are glued to the surface connection with the shaft rod 14.
- Fig. 5 indicates the corresponding adhesive joints 28, 29. These preferably extend over the flat body 26, 27 in each case over the entire surface.
- the flat bodies 26, 27 may have small projections (not illustrated), eg knobs, which rest against the flat side 23, 24 and define a gluing gap with a defined thickness.
- Fig. 4 also shows a first stop member 30 and a second Stop element 31.
- the two stop elements 30, 31 are connected to the flat bodies 26, 27, for example, welded or glued.
- the stop element 30 is, for example, an elongated metal rod with a rectangular cross-section. However, it can also find a metal hollow profile, a U-profile or the like application.
- a connection zone 32 is marked with cross-hatching. In this connection zone, the stop element 30 is connected to the flat body 27 and to the concealed corresponding side with the flat body 26.
- welding seams may be provided for the connection, for example laser welding seams.
- the stop element 30 is rigid and projects beyond the end edge 33 of the flat body 26 or 27 also.
- the stopper member 30 is on, as Fig. 2 shows, from the side support 16 remote side of the socket 25 is arranged. It overlaps the inner edge of the side support 16 and thus can at least partially project beyond the cross section thereof. In this way, thrust forces of the side support are reduced by being picked up by the abutment member 30 and transmitted to the socket 25.
- the second stop element 31 is preferably shorter. It protrudes less far beyond the edge 33. In addition, it is at least slightly movable on the stop member 30 and away from it. It can be like this Fig. 4 illustrated only in a small zone 34 rigidly connected to the flat bodies 26, 27 be. Again, in this zone 34, any suitable connection means, such as welds, welds, solder pads, pads, or the like, may be provided.
- the first stop element 30 and the second stop element 31 can also functional sections be an otherwise integrally formed use.
- the two stop elements 30, 31 is associated with a clamping means 35 which is adapted to bias the stop member 31 in the direction of the stop member 30.
- the clamping means 35 may be, for example, a clamping bolt 36. This can pass through a provided in the upper stop member 30 vertical hole 37 and be screwed into an aligned threaded bore 38 of the second stop member 31.
- the shaft rod 14 is provided in the region of the stop elements 30, 31 with recesses 39, 40 and in between with a further recess to form a pocket 41.
- This serves to accommodate one Fig. 3 visible extension 42 of the side support 16.
- the extension 42 has a height corresponding to the distance between the stop pieces 30, 31. It has a thickness which corresponds approximately to the distance between the flat parts 26, 27.
- the extension 42 is preferably slightly rounded or bevelled at its free end. It preferably has a rectangular cross-section.
- the side support 16 is provided in the vicinity of the extension 42 on both sides with a step 43, 44 or shoulder, which serves as a stop or contact surface for the edge 33.
- the edge 33 can, like it Fig. 2 indicates something about the front end of the shaft rod 14 protrude.
- a through hole 45 is provided in the side support 16, through which the clamping bolt 36 can find.
- an additional stop element for the extension 42 of the side support 16 can be introduced into the pocket 41, which, like the stop elements 30, 31, is held by the flat bodies 26, 27.
- 16 further structures may be provided on the side support, for example, an extension 46 for securing the axial position of one of the heddle rails or as a stop for sitting on the heald heald healds.
- the terminals 18, 19 may be directly or indirectly connected to the flat body 26, 27, for example, by welding seams or when the flat bodies extend correspondingly beyond the respective narrow side of the relevant shaft rod 14 or 15, by riveting or the like. If the first stop element 30 is located flush with the outer edge of the shaft rod 14, the terminals 18, 19 can also be bolted directly to the first stop element 30 or otherwise connected.
- the mobility can be increased if the stop element 31 has a corresponding spring zone 48.
- This can be formed by a preferably adjacent to the zone 34 recess 49, wherein the cross section of the stop element 31 is weakened.
- the recess 49 can, as shown, be provided on the side remote from the pocket 41 or else on the side of the stop element 31 facing the pocket 41.
- Other measures to weaken the cross section of the material and thus to increase the elasticity e.g. Drilling is also possible.
- Fig. 6 illustrates a modified embodiment of the socket 25.
- the connection between the stopper member 30 and the flat bodies 26, 27 may in turn be created by any material-fluid connection, such as welding, soldering, gluing or as indicated by screw or rivet.
- the connection between the stop element 31 and the flat bodies 26, 27 may be formed by a hinged joint 50.
- the hinge joint 50 may be formed, for example, by a bolt or pin extending between the flat bodies 26, 27, which engages through a bore of the stop element 31. This hole is transverse to the edge 33.
- the pin may be part of a screw or a rivet. Alternatively, the pin can sit in bores of the flat bodies 26, 27 and be pressed, welded, riveted or otherwise connected to them. Again, regardless of the elasticity of the stop element 31, a certain mobility is given to the stop element 30 or away from it. The function otherwise corresponds to that in connection with the embodiment according to FIG Fig. 4 described.
- the weaving shank according to the invention has at least one shaft rod, preferably made of lightweight material 14 and at least one side support 16. These are connected to each other via a corner joint 20, which is based on a specially trained version 25.
- the socket 25 comprises at least one, preferably two flat body 26, 27.
- the at least one flat body 26 is connected to two stop elements 30, 31, one of which is stationary and the other at least slightly movably held or mounted.

Die Erfindung betrifft einen Webschaft mit einem Schaftstab, der aus einem faserverstärkten Kunststoffmaterial aufgebaut ist. Insbesondere betrifft die Erfindung die Verbindung zwischen den Seitenstützen des Webschafts und den Schaftstäben.The invention relates to a heald with a shaft rod, which is constructed of a fiber-reinforced plastic material. In particular, the invention relates to the connection between the side supports of the heald and the shaft rods.
Webschäfte sind in der Regel rechteckige rahmenförmige Gebilde mit langen horizontal angeordneten Schaftstäben und vertikalen Seitenstützen, die die Schaftstäbe an ihren jeweiligen Enden untereinander verbinden. Die Schaftstäbe tragen Litzentragschienen zur Aufnahme von Weblitzen. Die Grundstruktur eines solchen Webschafts kann bspw. der

Nach ähnlichem Prinzip arbeitet die Eckverbindung gemäß
Die vorgenannten Prinzipien stoßen auf Schwierigkeiten bei der Anwendung an Kunststoffschaftstäben, insbesondere faserverstärkten Stäben.The above principles encounter difficulties when used on plastic shaft rods, in particular fiber-reinforced rods.
Es ist Aufgabe der Erfindung einen Eckverbinder für Leichtbauschaftstäbe anzugeben.It is an object of the invention to provide a corner connector for lightweight construction bars.
Diese Aufgabe wird mit dem Webschaft nach Anspruch 1 gelöst:
- Der erfindungsgemäße Webschaft weist einen Leichtbauschaftstab aus einem faserverstärkten Kunststoffmaterial, beispielsweise mit Karbonfasern, auf. Es kann sich dabei um ein Vollprofil oder ein Hohlprofil handeln. Die zur Verstärkung vorgesehenen Fasern können Langfasern oder Kurzfasern sein. Sie können geordnet oder ungeordnet in dem Kunststoff angeordnet sein. Sie können als Gewebe, Gestricke, Rowings, Einzelfäden, Seile oder dergleichen angeordnet sein. Sie können sich zum Beispiel vorwiegend in Schaftlängsrichtung und/oder auch in anderen Richtungen erstrecken. Es kann sich um organische oder anorganische Fasern, Kohlenstofffasern oder dergleichen handeln. Die Fasern sind in eine Matrix, vorzugsweise eine Kunststoffmatrix oder auch Metallmatrix, bspw. in eine Magnesium-Aluminium-Metallmatrix eingebunden.
- The heddle according to the invention has a lightweight push rod made of a fiber-reinforced plastic material, for example with carbon fibers. It may be a solid profile or a hollow profile. The reinforcing fibers may be long fibers or short fibers. They may be arranged in order or disordered in the plastic. They can be arranged as fabrics, knits, rovings, monofilaments, ropes or the like. For example, they may extend predominantly in the longitudinal direction of the shaft and / or in other directions. It may be organic or inorganic fibers, carbon fibers or the like. The fibers are embedded in a matrix, preferably a plastic matrix or metal matrix, for example in a magnesium-aluminum-metal matrix.
An dem Schaftstab ist eine Fassung angebracht, die zwei Flachkörper aufweist. Diese sind mit Abschnitten, vorzugsweise Endabschnitten der beiden Seitenflächen verklebt oder auf andere geeignete Weise flächenhaft verbunden. Die Flachkörper können bspw. Blechplatten, Kunststoffplatten oder dergleichen sein. Sie können eine einheitliche Dicke oder wechselnde Dicken aufweisen. Zum Beispiel können sich die Flachkörper von dem Ende des Schaftstabs weg zur Mitte hin verjüngen. Dies kann dazu beitragen, die an dem Eckverbinder wirkenden Kräfte großflächig und ohne lokale Sprünge auf den Schaftstab zu übertragen. Eine alternative Ausführungsform kommt mit nur einem Flachkörper aus. Dazu wird der Flachkörper in einem zu den Flachseiten des Schaftstabs planparallelen Schlitz im Schaftstab beidseitig verklebt.On the shaft rod a socket is attached, which has two flat body. These are glued to sections, preferably end portions of the two side surfaces or connected in a planar manner in other suitable manner. The flat bodies may be, for example, sheet metal plates, plastic plates or the like. They can have a uniform thickness or varying thicknesses. For example, the flat bodies may taper away from the end of the shaft rod towards the center. This can contribute to the forces acting on the corner connector over a large area and without local To transfer jumps on the shaft rod. An alternative embodiment comes with only a flat body. For this purpose, the flat body is glued on both sides in a plane-parallel to the flat sides of the shaft rod slot in the shaft rod.
Zwischen den beiden Flachkörpern sind ein erstes starres Anschlagelement und ein zweites, auf das erste Anschlagelement hin spannbares weiteres Anschlagelement angeordnet. Ein Spannmittel kann das zweite Anschlagelement gegen das erste Anschlagelement spannen. Zwischen beiden Anschlagelementen ist durch eine entsprechende Aussparung des Schaftstabs eine Tasche gebildet. In dieser Tasche kann ein sich von der Seitenstütze weg erstreckender zwischen den beiden Anschlagelementen aufgenommener Fortsatz festgespannt und so eine feste Verbindung zwischen dem Schaftstab und der Seitenstütze hergestellt werden. Weil der erste Anschlag starr und der zweite Anschlag federnd ausgebildet oder federnd, schwenkbar oder auf sonstige Weise wenigstens geringfügig beweglich gelagert ist, ist einerseits ein sicheres Spannen des Fortsatzes der Seitenstütze und somit eine sichere Befestigung wie andererseits auch eine starre Kopplung zwischen Seitenstütze und Schaftstab gegeben, wenn die Verbindung festgespannt ist. Das erste Anschlagelement und das zweite Anschlagelement sind vorzugsweise unabhängig voneinander an den Flachkörpern angeordnete Elemente. Alternativ dazu kann das erste Anschlagelement und das zweite Anschlagelement ein funktioneller Abschnitt eines einstückigen Einsatzes sein, welcher zwischen den Flachkörpern angeordnet ist.Between the two flat bodies, a first rigid stop element and a second, on the first stop element towards further tensionable stop element are arranged. A tensioning means can tension the second stop element against the first stop element. Between the two stop elements, a pocket is formed by a corresponding recess of the shaft rod. In this pocket, an extension extending from the side support extending between the two stop elements can be tightened to form a firm connection between the shaft post and the side support. Because the first stop is rigid and the second stop resiliently mounted or resiliently, pivotally or otherwise mounted at least slightly movable, on the one hand a secure clamping of the extension of the side support and thus secure attachment as on the other hand given a rigid coupling between side support and shaft rod when the connection is tightened. The first stop element and the second stop element are preferably arranged independently of one another on the flat bodies. Alternatively, the first stopper member and the second stopper member may be a functional portion of a one-piece insert disposed between the flat bodies.
Weiter ist es möglich, auf das zweite Anschlagelement gänzlich zu verzichten. Der Fortsatz der Seitenstütze kann mit einer Gewindebohrung versehen sein, in die ein Bolzen greift, der sich durch das erste Anschlagelement erstreckt. Das erste Anschlagelement liegt vorzugsweise auf der von der Seitenstütze weg weisenden Seite des Fortsatzes.Further, it is possible to dispense entirely with the second stop element. The extension of the side support may be provided with a threaded bore into which a bolt engages extending through the first stop member. The first stop element preferably lies on the side of the extension pointing away from the side support.
Die Erfindung verbindet mehrere Vorteile. Sie bietet ein Konzept zum sicheren Anschließen von Seitenstützen an Schaftstäbe aus Leichtbaumaterialien, die hinsichtlich lokaler Krafteinleitung durchaus empfindlich sein können. Solche Leichtbauschaftstäbe können bspw. aus faserverstärkten Kunststoffen als Vollkörper oder als Hohlkörper gebildet sein. Sie können auch aus Leichtmetall gebildet sein, insbesondere Aluminium- und/oder Magnesiumlegierungen, z.B. in Form entsprechend dünner Bleche, zwischen denen Schaumkörper, Wabenkörper oder dergleichen zur Verstärkung gehalten sein können. Es kann sich auch um Schaftstäbe aus Leichtmetall als Vollkörper oder als Hohlkörper handeln. Der erfindungsgemäße Eckverbinder kann bei Schaftstäben aller oben genannten und ähnlichen Arten angewendet werden.The invention combines several advantages. It offers a concept for the safe connection of side supports to shaft rods made of lightweight construction materials, which can be quite sensitive to the local application of force. Such lightweight construction bars may, for example, be formed from fiber-reinforced plastics as a solid body or as a hollow body. They may also be formed of light metal, in particular aluminum and / or magnesium alloys, e.g. in the form of correspondingly thin sheets, between which foam body, honeycomb body or the like can be kept for reinforcement. It may also be shaft rods made of light metal as a solid body or as a hollow body. The corner connector according to the invention can be applied to shaft rods of all the above and similar types.
Durch die unterschiedliche Ausbildung und/oder Anordnung der beiden Anschlagelemente wird eine Aufgabenteilung erreicht. Eines der Anschlagelemente dient zur Herstellung eines starren Kraftübertragungswegs zwischen den Seitenstützen und den Flachteilen während das andere Anschlagelement als Spannmittel dient.Due to the different design and / or arrangement of the two stop elements a division of responsibilities is achieved. One of the stop elements serves to produce a rigid force transmission path between the side supports and the flat parts while the other stop element serves as a tensioning means.
Der Webschaft weist wenigstens abschnittsweise ebene Seitenflächen auf. Vorzugsweise sind die Flachkörper an ebenen Partien der Seitenflächen angeordnet. Wenn der Schaftstab jedoch mindestens eine nicht ebene Seitenfläche aufweist, ist es auch möglich, den Flachkörper an die entsprechende nicht ebene Seitenfläche anzupassen, indem er mit einer entsprechenden komplementären Form versehen ist.The heald has at least partially planar side surfaces. Preferably, the flat bodies are arranged on flat parts of the side surfaces. However, if the shaft rod has at least one non-planar side surface, it is also possible to adapt the flat body to the corresponding non-planar side surface by providing it with a corresponding complementary shape.
Vorzugsweise sind die beiden Seitenflächen des Schaftstabs parallel zueinander orientiert. Der Schaftstab hat vorzugsweise einen Rechteckquerschnitt. Andere Querschnitte sind möglich.Preferably, the two side surfaces of the shaft rod are oriented parallel to each other. The shaft rod has preferably a rectangular cross-section. Other cross sections are possible.
Die Flachkörper können wie erwähnt Metallplatten sein. Insbesondere können sie Stahlplatten, Aluminiumplatten, Blechelemente oder ähnliches sein. Sie erstrecken sich vorzugsweise von einer Schmalseite des Schaftstabs zu seiner anderen. So wird eine großflächige Krafteinleitung erreicht. Die Metallplatten oder -bleche können mit dem Schaftstab flächenhaft verbunden, vorzugsweise verklebt sein. Vorzugsweise sind die Flachkörper an der den Schaftstab zugewandten Klebeseite mit mindestens einem vorzugsweisen mehreren Vorsprüngen, bspw. Leisten, Noppen oder dergleichen, versehen, deren Höhe die Dicke einer auszubildenden Klebefuge festlegt. Diese Erhebungen dienen als Abstandshaltermittel zur Qualitätssicherung bei der Herstellung der Klebeverbindung.The flat bodies can be as mentioned metal plates. In particular, they may be steel plates, aluminum plates, sheet metal elements or the like. They preferably extend from one narrow side of the shaft rod to its other. So a large force application is achieved. The metal plates or sheets can be integrally connected to the shaft rod, preferably glued. Preferably, the flat bodies are provided on the adhesive side facing the shaft rod with at least one preferably a plurality of projections, for example strips, knobs or the like, the height of which determines the thickness of an adhesive joint to be formed. These surveys serve as spacer means for quality assurance in the production of the adhesive bond.
Die Flachkörper können sich bedarfsweise etwas über die Schmalseiten des Schaftstabs erstrecken. Dies ist jedoch nicht unbedingt nötig. Vorzugsweise lassen sie zumindest eine Schmalseite des Schaftstabs frei.The flat body may, if necessary, extend slightly over the narrow sides of the shaft rod. However, this is not necessary. Preferably, they release at least one narrow side of the shaft rod.
Beide Anschlagselemente weisen vorzugsweise unterschiedliche Längen auf. Insbesondere ragt das starr angeordnete Anschlagelement vorzugsweise weiter aus der Stirnseite des Schaftstabs heraus als das andere zum Spannen dienende Anschlagelement. Vorzugsweise überragen jedoch beide Anschlagelemente den Flachkörper. Mit diesem Konzept kann das starre Anschlagelement insbesondere zur Übertragung von Schubkräften dienen, die von der Seitenstütze auf den Schaftstab zu übertragen sind. Vorzugsweise übergreift das längere starre Anschlagelement zumindest einen Teil des Querschnitts der Seitenstütze.Both stop elements preferably have different lengths. In particular, the rigidly arranged stop element preferably projects farther out of the end face of the shaft rod than the other stop element serving for clamping. Preferably, however, both stop elements project beyond the flat body. With this concept, the rigid stop element can be used in particular for the transmission of thrust forces which are to be transmitted from the side support to the shaft rod. Preferably, the longer rigid stop member engages over at least a portion of the cross section of the side support.
Das erste Anschlagelement ist mit den Flachkörpern vorzugsweise starr zum Beispiel durch Kleben oder Schweißen verbunden. Es können dazu einzelne Schweißpunkte oder Schweißnähte, bspw. Laserschweißnähte vorgesehen sein. Auch kann zwischen dem Flachkörper und dem Anschlagelement eine mechanische Verbindung durch einen oder mehrere Niete, einen oder mehrere Schrauben oder sonstige formschlüssige Befestigungsmittel vorgesehen sein.The first stop element is preferably rigidly connected to the flat bodies, for example by gluing or welding. It can be provided for this purpose individual welds or welds, for example. Laser welds. Also, between the flat body and the stop element, a mechanical connection can be provided by one or more rivets, one or more screws or other form-locking fastening means.
Das zweite Anschlagelement ist an zumindest einem Ende etwas beweglich. Diese Beweglichkeit kann erreicht werden, indem das Anschlagelement beweglich mit dem Flachkörper verbunden ist. Dazu können Schrauben, Niete oder dergleichen dienen. Es ist auch möglich, ein innen liegendes Ende des Anschlagelements mit einem oder beiden Flachkörpern zu verschweißen. Dazu können ein oder mehrere Schweißpunkte oder Schweißnähte dienen. Der sich von der Schweißstelle weg erstreckende Teil des Anschlagelements hat naturgegeben eine gewisse federnde Nachgiebigkeit, die genutzt werden kann, um die gewünschte geringe Beweglichkeit zu erreichen. Außerdem kann das Anschlagelement an einer oder mehreren Stellen eine Ausnehmung besitzen, um besser federn zu können.The second stop element is slightly movable on at least one end. This mobility can be achieved by the stop element is movably connected to the flat body. These screws, rivets or the like can be used. It is also possible to weld an inner end of the stop element with one or both flat bodies. This can be done with one or more welds or welds. The extending away from the weld part of the stop element has inherently a certain resilience, which can be used to achieve the desired low mobility. In addition, the stopper element may have a recess at one or more locations in order to be able to spring better.
Der Webschaft kann auf einen Schaftstab und eine oder zwei Seitenstützen reduziert sein. Solche Bauformen sind z.B. bei Webschäften anwendbar, die ein fest der Webmaschine zugeordnetes Unterteil und ein aus der Webmaschine herausnehmbares Oberteil aufweisen. Auch für solche reduzierten Webschäfte gelten alle oben beschriebenen Varianten. Vorzugsweise ist der Webschaft jedoch ein vollständiger rechteckiger Rahmen mit zwei Schaftstäben und zwei Seitenstützen.The heald may be reduced to a shaft bar and one or two side supports. Such designs are e.g. applicable to heald frames, which have a fixed part of the loom associated lower part and removable from the loom upper part. Also for such reduced heddle shafts apply all variants described above. Preferably, however, the heald is a complete rectangular frame with two shaft rods and two side supports.

Zur Verbindung der Seitestützen 16, 17 mit den Schaftstäben 14, 15 sind Eckverbinder vorgesehen, von denen in
Zu der Eckverbindung 20 gehört eine Fassung 25, die mit dem Schaftstab 14 fest verbunden ist. Im vorliegenden Ausführungsbeispiel gehören zu der Fassung 25 ein hinterer Flachkörper 26 und ein vorderer Flachkörper 27, die jeweils mit den Flachseiten 23, 24 fest verbunden sind. Die Flachkörper 26, 27 können im einfachsten Fall durch Blechplatten oder sonstige plattenförmige, beispielsweise aus Kunststoff bestehende Elemente, gebildet sein. Vorzugsweise bestehen die Flachkörper 26, 27 jedoch aus einem anderen Material oder einer anderen Materialzusammensetzung als der Schaftstab 14. Z.B. können die Flachkörper 26, 27 aus Aluminium oder Stahl bestehen. Die Flachkörper 26, 27 sind zur flächigen Verbindung mit dem Schaftstab 14 verklebt.
Zu der Fassung 25 gehören, wie insbesondere
Das zweite Anschlagelement 31 ist vorzugsweise kürzer ausgebildet. Es ragt weniger weit über die Kante 33 hinaus. Außerdem ist es wenigstens geringfügig auf das Anschlagelement 30 hin bzw. von diesem weg beweglich. Dazu kann es wie
Den beiden Anschlagelementen 30, 31 ist ein Spannmittel 35 zugeordnet, das dazu geeignet ist, das Anschlagelement 31 in Richtung auf das Anschlagelement 30 zu spannen. Das Spannmittel 35 kann beispielsweise ein Spannbolzen 36 sein. Dieser kann ein in dem oberen Anschlagelement 30 vorgesehenes vertikales Loch 37 durchgreifen und in eine fluchtende Gewindebohrung 38 des zweiten Anschlagelementes 31 eingeschraubt sein.The two

Ergänzend wird darauf hingewiesen, dass an der Seitenstütze 16 weitere Strukturen vorgesehen sein können, beispielsweise ein Fortsatz 46 zur axialen Lagesicherung einer der Litzentragschienen oder als Anschlag für die auf der Litzentragschiene sitzenden Weblitzen. Außerdem können die Anschlüsse 18, 19 direkt oder mittelbar an die Flachkörper 26, 27 angeschlossen sein, beispielsweise durch Schweißnähte oder wenn die Flachkörper sich entsprechend über die jeweilige Schmalseite des betreffenden Schaftstabs 14 oder 15 hinaus erstrecken, durch Nietverbindung oder ähnliches. Liegt das erste Anschlagelement 30 bündig an der Außenkante des Schaftstabs 14 an, so können die Anschlüsse 18, 19 auch direkt mit dem ersten Anschlagelement 30 verschraubt oder anderweitig verbunden sein.In addition, it should be noted that 16 further structures may be provided on the side support, for example, an
Die in soweit beschriebene Eckverbindung 20 funktioniert wie folgt:
- Zur Herstellung der Eckverbindung wird die
Seitenstütze 16mit ihrem Fortsatz 42 indie Tasche 41 eingefügt, bis die 43, 44 anStufen der jeweiligen Kante 33 anliegen. Es wird dann der Spannbolzen 36 durch die 37, 45 geführt und inBohrungen die Gewindebohrung 38 eingeschraubt. Durch Anziehen des Spannbolzens 36 wirddas Anschlagelement 31 fest gegenden Vorsprung 42 und dieser wiederum festgegen das Anschlagelement 30 gepresst. Die Eckverbindung ist nun betriebssicher hergestellt. Der Abstand zwischen der Gewindebohrung 38 und derZone 34 sichert dabei eine gewisse geringe Beweglichkeit des Anschlagelements 31, die inFig. 4 durch einen Doppelpfeil angedeutet ist. Die Beweglichkeit kann sich auf wenige zehntel Millimeter beschränken und ist ausreichend, um einer Seite ein leichtes Ein- und Ausführen des Fortsatzes 42 in die bzw. aus derTasche 41 zu ermöglichen und andererseitsden Fortsatz 42 sicher festspannen zu können.
- To produce the corner joint, the
side support 16 is inserted with itsextension 42 into thepocket 41 until the 43, 44 rest against thesteps respective edge 33. It is then the clampingbolt 36 is guided through the 37, 45 and screwed into the threaded bore 38. By tightening the clampingbores bolt 36, thestop member 31 is pressed firmly against theprojection 42 and this in turn firmly against thestop member 30. The corner joint is now made reliable. The distance between the threaded bore 38 and thezone 34 ensures a certain low mobility of thestop member 31, the inFig. 4 indicated by a double arrow. The mobility can be limited to a few tenths of a millimeter and is sufficient to allow one side easy insertion and removal of theextension 42 in and out of thepocket 41 and on the other hand to securely clamp theextension 42 can.
Die Beweglichkeit kann erhöht werden, wenn das Anschlagelement 31 eine entsprechende Federzone 48 aufweist. Diese kann durch eine vorzugsweise der Zone 34 benachbarten Ausnehmung 49 gebildet sein, bei der der Querschnitt des Anschlagelements 31 geschwächt ist. Die Ausnehmung 49 kann, wie dargestellt, an der von der Tasche 41 abliegenden Seite oder auch an der der Tasche 41 zugewandten Seite des Anschlagelements 31 vorgesehen sein. Andere Maßnahmen zur Schwächung des Materialquerschnitts und somit zur Erhöhung der Elastizität, z.B. Bohrungen, sind ebenfalls möglich.The mobility can be increased if the
Der erfindungsgemäße Webschaft weist mindestens einen vorzugsweise aus Leichtbaumaterial bestehenden Schaftstab 14 und mindestens eine Seitenstütze 16 auf. Diese sind über eine Eckverbindung 20 miteinander verbunden, die auf einer speziell ausgebildeten Fassung 25 beruht. Die Fassung 25 umfasst mindestens einen, vorzugsweise zwei Flachkörper 26, 27. Der mindestens eine Flachkörper 26 ist mit zwei Anschlagelementen 30, 31 verbunden, von denen eines ortsfest und das andere wenigstens geringfügig beweglich gehalten oder montiert ist. Die beiden Anschlagelemente 30, 31 überragen die stirnseitige Kante 33 des Flachkörpers 26 unterschiedlich weit. Zwischen beiden Anschlagelementen 30, 31 ist ein Spannmittel 35 wirksam, dass dazu dient, das kürzere Anschlagelement 31 auf das längere Anschlagelement 30 hin zu spannen, um zwischen den Anschlagelementen 30, 31 einen Fortsatz 42 der Seitenstütze 16 festzuklemmen. Der Flachkörper 26 überträgt Kräfte zwischen der Seitenstütze 16 und dem Schaftstab 14 großflächig auf diesem.The weaving shank according to the invention has at least one shaft rod, preferably made of
