Description

Die Erfindung betrifft einen Webschaft für Webmaschinen.The invention relates to a weaving shank for weaving machines.

Sogenannte Webschäfte sind rahmenförmige Anordnungen mit einem langen horizontalen oberen Schaftstab und einem darunter angeordneten langen, horizontalen unteren Schaftstab. Die Enden beider Schaftstäbe sind durch Seitenstützen verbunden. Die Schaftstäbe tragen Litzentragschienen, auf denen Weblitzen sitzen. Zum Aufziehen und Abnehmen von Weblitzen muss der Webschaft demontierbar sein. Dazu sind die Seitenstützen abnehmbar ausgebildet. Zur Verbindung der Schaftstäbe und der Seitenstützen dienen lösbare Eckverbinder. Beispiele dafür sind bspw. aus der
DE 10 2005 029 701 B3 oder auch aus der DE 103 49 381 B4 bekannt.So-called heald frames are frame-shaped arrangements with a long horizontal upper shaft rod and arranged underneath a long, horizontal lower shaft rod. The ends of both shaft rods are connected by side supports. The shaft rods carry Litzentragschienen on which healds sit. To raise and remove healds, the heald must be removable. For this purpose, the side supports are removable. To connect the shaft rods and the side supports are releasable corner connectors. Examples of this are, for example, from the
DE 10 2005 029 701 B3 or even from the DE 103 49 381 B4 known.

Aus der EP 2 009 158 A1 ist ein Webschaft bekannt mit einem Schaftstab, in dessen offenes Ende ein Klemmfortsatz einer Seitenstütze einschiebbar ist. Eine Spannschraube ist dazu vorgesehen, eine Klemmfeder gegen die obere Horizontalfläche des Klemmfortsatzes zu drücken. Zur Aufnahme der von der Feder auf den Fortsatz ausgeübten Klemmkräfte ist der Schaftstab von einer Manschette umgriffen, die sich über die beiden voneinander weg weisenden vertikalen Flachseiten des Schaftstabs erstreckt.From the EP 2 009 158 A1 is a heald known with a shaft rod in the open end of a compression extension of a side support is inserted. A clamping screw is provided to press a clamping spring against the upper horizontal surface of the clamping extension. To accommodate the force exerted by the spring on the extension clamping forces of the shaft rod is encompassed by a sleeve, which extends over the two facing away from each other vertical flat sides of the shaft rod.

Größere Löcher oder Öffnungen, die zu Verletzungen von Bedienpersonal führen könnten sind nicht vorhanden.Larger holes or openings that could lead to injuries of operating personnel are not available.

Die CH 427688 A wie auch die DE 101 16 813 B4 offenbaren das Prinzip eines Eckverbinders mit zwei aus dem Schaftstab herausgearbeiteten Klemmschenkeln, zwischen denen ein Fortsatz der Seitenstütze festgeklemmt wird.The CH 427688 A as well as the DE 101 16 813 B4 disclose the principle of a corner connector with two out of the shaft rod worked out clamping legs, between which an extension of the side support is clamped.

Es ist Ziel der Erfindung Gefahren, zu minimieren, die von den Webschäften für Bediener ausgehen.It is an object of the invention to minimize hazards arising from the healds for operators.

Gerade beim Einrichten einer Webmaschine bei Betriebsunterbrechungen infolge von Betriebsstörungen oder bei anderen Gelegenheiten, müssen Bedienpersonen Zugang zu den Webschäften haben, wobei auch zumindest eine langsame Bewegung der Webschäfte möglich sein muss. In solchen Fällen muss wirksam verhindert werden, dass sich Bedienpersonen verletzen oder sonst zu Schaden kommen.Especially when setting up a loom in case of business interruptions due to malfunction or other occasions, operators must have access to the heald, and at least a slow movement of the heald must be possible. In such cases, it must be effectively prevented that operators injure or otherwise be harmed.

Es ist Aufgabe der Erfindung, einen Webschaft mit verbesserter Sicherheit zu schaffen.It is an object of the invention to provide a heddle with improved safety.

Diese Aufgabe wird mit dem Webschaft nach Anspruch 1 gelöst:

  • Der erfindungsgemäße Webschaft weist mindestens einen Eckverbinder auf, der einen zu mindestens einer der Flachseiten des Schaftstabs offenen Hohlraum beinhaltet. Der Hohlraum wird von zwei Schenkeln begrenzt, die vorzugsweise Teil des Schaftstabs sind und vorzugsweise eine Länge aufweisen, die deutlich größer ist als die Länge des zwischen ihn aufzunehmenden Fortsatzes der Seitenstütze. Insoweit verbleibt eine erhebliche Öffnung, die die Seitenfläche durchsetzt. Das an oder in der Öffnung angeordnete Schutzelement versperrt den Zugang zu der Öffnung, so dass Bedienpersonal weder mit Werkzeug noch mit Teilen der Bekleidung oder Fingern in diese Öffnung hinein gelangen kann. Somit wird die Verletzungsgefahr beim Hantieren an dem Webschaft erheblich reduziert.
This object is achieved with the weaving shaft according to claim 1:
  • The weaving shank according to the invention has at least one corner connector, which contains a cavity which is open to at least one of the flat sides of the shaft rod. The cavity is bounded by two legs, which are preferably part of the shaft rod and preferably have a length which is significantly greater than the length of the extension of the side support to be received between them. In that regard, remains a significant opening that passes through the side surface. The protection element arranged on or in the opening obstructs access to the opening, so that operating personnel can not get into this opening either with tools or with parts of the clothing or fingers. Thus, the risk of injury when handling the hive considerably reduced.

An den Schenkeln sind Klemmbacken befestigt, die über ein Spannmittel zueinander spannbar sind, um den Fortsatz der Seitenstütze zwischen einander festzuspannen. Diese Klemmbacken können aus einem massiven Material insbesondere Metall, bspw. Stahl ausgebildet sein. Unabhängig davon können die Webschäfte aus anderem Material, vorzugsweise Aluminium ausgebildet sein. Die Klemmbacken können mit den Schenkeln fest oder beweglich verbunden sein. Zwischen den beiden Klemmbacken ist ein Abstand vorhanden, der vorzugsweise mehrere Zentimeter beträgt, jedenfalls aber so groß, dass ein durchschnittlicher Bediener mit Daumen oder Finger in die Öffnung zwischen die Klemmbacken greifen könnte, wäre dort nicht das Schutzelement angeordnet.On the legs jaws are attached, which are clamped to each other via a clamping means to clamp the extension of the side support between each other. These jaws can be formed of a solid material, in particular metal, for example steel. Regardless of the heald of other material, preferably aluminum may be formed. The jaws can be firmly or movably connected to the legs. Between the two jaws there is a distance, which is preferably several centimeters, but in any case so large that an average operator could reach into the opening between the jaws with his thumb or fingers if the protective element were not arranged there.

Vorzugsweise nimmt der Fortsatz weniger als die Hälfte des Volumens der Öffnung ein. Im bevorzugten Ausführungsfall nimmt der Fortsatz weniger als ein Drittel des Volumens ein. Er ist somit nur zwischen den Enden der Schenkel geklemmt während der größte Teil der Öffnung frei bleibt. Die somit relativ langen Schenkel schwenken beim Spannen nur sehr wenig, so dass an dem zwischen ihnen geklemmten Fortsatz eine gleichmäßige Flächenpressung und somit eine großflächige Kraftübertragung gegeben ist.Preferably, the extension occupies less than half the volume of the opening. In the preferred embodiment, the extension occupies less than one third of the volume. He is thus clamped only between the ends of the legs while the largest part of the opening remains free. The thus relatively long legs pivot during clamping only very little, so that at the clamped between them extension a uniform surface pressure and thus a large-scale power transmission is given.

Mindestens der größere Teil der Öffnung wird von dem Schutzelement abgedeckt. Vorzugsweise ist die Abdeckung vollständig. Alternativ können kleinere Flächen oder Öffnungen, die so gering sind, dass ein Bediener mit seinem Finger nicht hineingreifen kann, auch frei bleiben. Insoweit kann das Schutzelement sowohl als geschlossenes, flächenhaftes Element ausgebildet sein als auch alternativ eine oder mehrere kleinere Öffnungen aufweisen.At least the major part of the opening is covered by the protective element. Preferably, the cover is complete. Alternatively, smaller areas or openings that are so small that an operator can not reach in with his finger can also remain free. In that regard, the protective element may be formed both as a closed, sheet-like element and alternatively have one or more smaller openings.

Das Schutzelement ist vorzugsweise mittels mindestens eines Befestigungselements an dem Webschaft gehalten. Das Befestigungselement kann bspw. ein sich quer durch die Öffnung erstreckender Rastfinger sein. Während das Schutzelement vorzugsweise um den Rand der Öffnung herum an einer der Flachseiten anliegt, hintergreift der Rastfinger dann vorzugsweise die andere Flachseite. Es hat sich gezeigt, dass diese Art der Befestigung ein einfaches Anbringen des Schutzelements an dem Schaftstab gestattet und auch sicherstellt, dass sich das Schutzelement auch bei hohen Beschleunigungen des Schaftstabs nicht von allein löst.The protective element is preferably held on the heald by means of at least one fastening element. The fastening element may, for example, be a latching finger extending transversely through the opening. While the protective element preferably bears against the edge of the opening on one of the flat sides, the latching finger then preferably engages behind the other flat side. It has been found that this type of attachment allows a simple attachment of the protective element to the shaft rod and also ensures that the protective element does not come loose even at high accelerations of the shaft rod.

Alternativ kann das Schutzelement mit anderen Mitteln an dem Schaftstab befestigt werden. Zum Beispiel kann es durch Klebstoff oder Haftstoff an dem Schaftstab befestigt werden. Es erstreckt sich dabei zumindest entlang eines Teils des die Öffnung umgebenden, zu der Flachseite gehörigen Rands und ist dort mit der Flachseite verklebt.Alternatively, the protective element may be secured to the shaft rod by other means. For example, it may be attached to the shaft rod by adhesive or adhesive. It extends at least along part of the surrounding the opening, belonging to the flat side edge and is glued to the flat side.

Das Schutzelement kann jedoch auch ein Körper sein, der in der Öffnung angeordnet und dort gehalten ist. Die Befestigung kann wiederum durch Klemmung, durch Klebung oder auch Rastung ermöglich werden.However, the protective element may also be a body which is arranged in the opening and held there. The attachment can in turn be made possible by clamping, by gluing or latching.

Das Schutzelement ist unabhängig von seiner Bauform vorzugsweise aus einem Kunststoff, z.B. einem durchsichtigen oder undurchsichtigen Kunststoff ausgebildet. Vorzugsweise ist das Schutzelement insoweit nachgiebig, dass es die geringfügige Relativbewegung der beiden die Öffnung begrenzenden Schenkel nicht behindert, die beim Festklemmen oder Freigeben des Fortsatzes der Seitenstütze auftritt.The protective element, regardless of its design, is preferably made of a plastic, e.g. a transparent or opaque plastic. Preferably, the protective element is compliant to the extent that it does not hinder the slight relative movement of the two limbs delimiting the opening, which occurs when clamping or releasing the extension of the side support.

For connection between the side supports 13, 14 and the shaft rods 11, 12 Eckverbindungseinrichtungen 16 to 19 are provided, which are each constructed in the same way. Accordingly, the following description of the Eckverbindungseinrichtung 16 is representative of the other Eckverbindungseinrichtungen 17 to 19.

Figur 2 veranschaulicht das obere Ende der linken Seitenstütze 13 und das linke Ende des oberen Schaftstabs 11. Insoweit wird hier die Eckverbindungseinrichtung 16 besonders dargestellt. FIG. 2 illustrates the upper end of the left side support 13 and the left end of the upper shaft rod 11. In this respect, the corner joint 16 is particularly shown here.

Die Seitenstütze 13 erstreckt sich im Gebrauch in Vertikalrichtung und ist in der Webmaschine vertikal beweglich geführt. Sie weist einen im Wesentlichen geraden Schaft 20 auf, von dem oben ein horizontaler Fortsatz 21 z.B. im rechten Winkel zu dem Schaft 20 weg ragt. Der Fortsatz 21 weist z.B. einen Rechteckquerschnitt auf. Vorzugsweise weist er eine horizontale Dicke auf, die nicht größer ist als die geringe Dicke des oberen Schaftstabs 11.The side support 13 extends in use in the vertical direction and is guided vertically movable in the weaving machine. It has a substantially straight shank 20 from which a horizontal extension 21 protrudes, for example, at right angles to the shaft 20. The extension 21 has, for example, a rectangular cross-section. Preferably, it has a horizontal thickness which is not greater than the small thickness of the upper shaft rod 11.

Der Schaftstab 11 ist an seinem Ende 22 mit einer Öffnung 23 versehen, die sich von dem stirnseitigen Ende ausgehend in den Schaftstab 11 hinein erstreckt und auch seine beiden Flachseiten 24, 25 durchsetzt. Insoweit ist eine maulartige Öffnung gebildet, die von seinem oberen Schenkel 26 und einem unteren Schenkel 27 begrenzt ist. Die beiden Schenkel 26, 27 sind vorzugsweise mit Klemmstücken 28, 29 versehen, die bspw. aus Stahl oder massivem Aluminium oder einem anderen Material bestehen können. Während der Schaftstab 11 insgesamt als Leichtbau-Hohlprofil ausgebildet sein kann, sind die Klemmstücke 28, 29 vorzugsweise massiv. Sie können mit den Schenkeln 26, 27 vernietet, verschraubt oder anderweitig verbunden sein. Der Abstand zwischen den einander zugewandten, vorzugsweise plan ausgebildeten, Klemmflächen der Klemmschenkel 28, 29 stimmt vorzugsweise im Wesentlichen mit dem Abstand der oberen und unteren Fläche des Fortsatzes 21 überein. Der Fortsatz 21 lässt sich somit leicht zwischen die Schenkel 26, 27 einfügen.The shaft rod 11 is provided at its end 22 with an opening 23 which extends from the front end starting in the shaft rod 11 and also its two flat sides 24, 25 passes. In that regard, a mouth-like opening is formed, which is bounded by its upper leg 26 and a lower leg 27. The two legs 26, 27 are preferably provided with clamping pieces 28, 29, which may, for example, consist of steel or solid aluminum or another material. While the shaft rod 11 may be formed overall as a lightweight hollow profile, the clamping pieces 28, 29 are preferably solid. They can be riveted, bolted or otherwise connected with the legs 26, 27. The distance between the mutually facing, preferably plane, clamping surfaces of the clamping legs 28, 29 preferably substantially coincides with the distance of the upper and lower surfaces of the extension 21. The extension 21 can thus be easily inserted between the legs 26, 27.

Während das obere Klemmstück 28 eine Durchgangsöffnung aufweist, ist in dem unteren Klemmstück 29 eine mit dieser fluchtenden Gewindebohrung angeordnet. Der Fortsatz 21 weist eine mit diesen Bohrungen fluchtende Durchgangsbohrung auf. Somit kann ein Spannmittel z.B. in Form eines Spannbolzens 30 oder eines anderen Elements durch die Bohrungen geführt und in die Gewindebohrung des unteren Klemmstücks 29 eingeschraubt werden. Wird der Spannbolzen 30 festgezogen, bewegen sich die Schenkel 26, 27 geringfügig federnd und der Fortsatz 21 wird zwischen den beiden Klemmstücken 28, 29 festgeklemmt.While the upper clamping piece 28 has a passage opening, a threaded bore aligned with this is arranged in the lower clamping piece 29. The extension 21 has an aligned with these holes through bore. Thus, a tensioning means may e.g. be guided in the form of a clamping bolt 30 or other element through the holes and screwed into the threaded bore of the lower clamping piece 29. If the clamping bolt 30 is tightened, the legs 26, 27 move slightly resilient and the extension 21 is clamped between the two clamping pieces 28, 29.

Diese Funktion wird insbesondere dann vorbildlich erreicht, wenn die Öffnung 23 eine von dem stirnseitigen Ende des Schaftstabs 11 weg in Horizontalrichtung gemessene Tiefe aufweist, die wesentlich größer als die in gleiche Richtung gemessene Länge des Fortsatzes 21 ist. Insoweit bleibt ein großer Teil der Öffnung 23 zu der Flachseite 24 bzw. 25 hin offen. Zur Abdeckung der verbleibenden Öffnung 23 zu wenigstens einer der Flachseiten 24, 25 hin, ist ein Schutzelement 31 vorgesehen, das die Öffnung 23 im vorliegenden Ausführungsbeispiel zu der Flachseite 24 hin abdeckt. Das Schutzelement 31 ist in den Figuren 3 und 4 gesondert veranschaulicht. Es wird bspw. durch eine dünne Kunststoffplatte gebildet, die zu der Form der Öffnung 23 passend ausgebildet ist. Sie erstreckt sich über den Rand 32 der Öffnung 23 und liegt entsprechend an dem randständigen Teil der Flachseite 24 an. Zum Beispiel in Gestalt von Rastfingern ausgebildete Befestigungskrallen 33 bis 37 erstrecken sich ungefähr rechtwinklig von der der Öffnung 23 zugewandeten Seite des plattenförmigen Körpers des Schutzelements 31 weg. An ihrem jeweiligen freien Ende sind die Befestigungskrallen 33 bis 37 mit Rastnasen oder sonstigen Vorsprüngen versehen, die hinter den Rand der Öffnung 23 greifen können, um das Schutzelement 31 an der gegenüberliegenden Flachseite 25 zu halten. Die Befestigungskrallen 33 bis 37 sind dem Rand 32 der Öffnung 23 folgend angeordnet.This function is particularly exemplary achieved when the opening 23 a measured from the front end of the shaft rod 11 in the horizontal direction depth which is substantially larger than the length of the extension 21 measured in the same direction. In that regard, a large part of the opening 23 remains open to the flat side 24 and 25, respectively. To cover the remaining opening 23 to at least one of the flat sides 24, 25, a protective element 31 is provided, which covers the opening 23 in the present embodiment to the flat side 24 out. The protective element 31 is in the FIGS. 3 and 4 separately illustrated. It is formed, for example, by a thin plastic plate which is formed to match the shape of the opening 23. It extends over the edge 32 of the opening 23 and is located at the marginal part of the flat side 24 accordingly. For example, in the form of locking fingers trained mounting claws 33 to 37 extend approximately at right angles to the opening 23 facing side of the plate-shaped body of the protective element 31 away. At their respective free end, the fastening claws 33 to 37 are provided with locking lugs or other projections which can engage behind the edge of the opening 23 in order to hold the protective element 31 on the opposite flat side 25. The fastening claws 33 to 37 are arranged following the edge 32 of the opening 23.

Die Öffnung 23 ist vorzugsweise von den zueinander parallelen Schenkeln begrenzt, wobei sie gerade Kanten aufweist. Diese beiden geraden Kanten gehen in einem bogenförmigen Endabschnitt ineinander über. Entsprechend ist der plattenförmige Grundkörper des Schutzelements 31 mit zwei zueinander parallelen geraden Kanten 38, 39 versehen, die durch einen bogenförmigen, vorzugsweise kreisbogenförmigen Kantenabschnitt 40 untereinander verbunden sind. Im Nachbarschaft zu den geraden Kanten 38, 39 kann die Dicke des plattenförmigen Grundkörpers des Schutzelements 31 reduziert sein. Es sind so randoffen Nuten 41, 42 gebildet, die der Aufnahme von seitlich überstehenden Partien der Klemmstücke 28, 29 dienen.The opening 23 is preferably bounded by the mutually parallel legs, wherein it has straight edges. These two straight edges merge into one another in an arcuate end section. Accordingly, the plate-shaped main body of the protective element 31 is provided with two mutually parallel straight edges 38, 39, which are interconnected by an arcuate, preferably circular arc-shaped edge portion 40. In the vicinity of the straight edges 38, 39, the thickness of the plate-shaped main body of the protective element 31 can be reduced. There are so edge-open grooves 41, 42 are formed, the the inclusion of laterally projecting parts of the clamping pieces 28, 29 serve.

Wie insbesondere Figur 3 erkennen lässt, ist die Dicke des plattenförmigen Grundkörpers des Schutzelements 31 gering. An der nach außen weisenden in Figur 3 oben liegenden Seite ist es vorzugsweise plan ausgebildet. Das Schutzelement 31 wird an den in einer Webmaschine angebrachten Webschäften vorzugsweise an den in der Webschaftgruppe außen stehenden Webschäften, vorzugsweise an der nach außen weisenden Flachseite derselben, angeordnet. Auf diese Weise wird verhindert, dass ein Bediener versehentlich in die Öffnung 23 greifen und bei Einschalten der Maschine oder auch im langsamen Betrieb, z.B. beim Einrichten, eine Quetschung erfährt. In der Webmaschine sind gleichartige Webschäfte in enger Nachbarschaft angeordnet. Ein die Öffnungen 23 benachbarter Webschäfte durchgreifender Finger würde bei einer Relativbewegung der Webschäfte ansonsten gequetscht, verletzt oder abgetrennt.In particular FIG. 3 can be seen, the thickness of the plate-shaped main body of the protective element 31 is low. At the outward facing in FIG. 3 overhead side, it is preferably flat. The protective element 31 is preferably arranged on the weaving shafts mounted in a weaving machine on the weaving shafts which are arranged on the outside in the weaving sheaf group, preferably on the outwardly facing flat side thereof. In this way it is prevented that a user inadvertently reach into the opening 23 and suffers a crushing when switching on the machine or even during slow operation, eg during setup. In the loom similar Webschäfte are arranged in close proximity. A finger passing through the openings 23 of adjacent healds would otherwise be squeezed, injured or separated during a relative movement of the heddle shafts.

Das Schutzelement 31 kann auch anderweitig ausgebildet sein. Figuren 5 bis 7 veranschaulichen eine alternative Ausführungsform eines Schutzelements 43, das als Füllkörper ausgebildet ist. Dieser ist in der Öffnung 23 anzuordnen und versperrt so den Zugang zu ihr von der Flachseite her. Der Füllkörper 43 weist eine Form auf, die an die Form der Öffnung 23 angepasst ist. Die Dicke des Schutzelements 43 ist aus Figur 7 ersichtlich. Die zwischen seinen beiden Flachseiten 44, 45 zu messende Dicke entspricht vorzugsweise der zwischen den beiden Flachseiten 24, 25 zu messenden Dicke des Schaftstabs 11. Der Füllkörper 43 weist außerdem eine obere und eine untere Schmalfläche 46, 47 auf, die dafür eingerichtet sind, mit den Klemmstücken 28, 29 in Anlage zu kommen. An dem Ende der Schmalfläche 46 ist eine Stufe 48 vorgesehen, bei der sich die Höhe des Füllkörpers 43 vergrößert. Eine entsprechende Stufe 49 ist im Anschluss an die untere Schmalfläche 47 vorgesehen. An die Stufen 48, 49 schließt sich ein zunächst gerader und dann bogenförmiger Rand 50 an, der die Seitenwände des Schaftstabs 11 hintergreift und somit den Füllkörper 43 in der Öffnung 23 sichert.The protective element 31 can also be formed otherwise. FIGS. 5 to 7 illustrate an alternative embodiment of a protective element 43, which is designed as a filler. This is to be arranged in the opening 23 and thus blocks access to it from the flat side. The filler 43 has a shape that is adapted to the shape of the opening 23. The thickness of the protective element 43 is made FIG. 7 seen. The thickness to be measured between its two flat sides 44, 45 preferably corresponds to the thickness of the shaft rod 11 to be measured between the two flat sides 24, 25. The filling body 43 also has an upper and a lower narrow surface 46, 47 which are adapted to the clamping pieces 28, 29 come into contact. At the end of the narrow surface 46, a step 48 is provided, in which the height of the filling body 43 increased. A corresponding step 49 is provided following the lower narrow surface 47. Adjoining the steps 48, 49 is an initially straight and then arcuate edge 50, which engages behind the side walls of the shaft rod 11 and thus secures the filling body 43 in the opening 23.

In Gebrauch füllt der Füllkörper 43 die Öffnung 23 so weit aus, dass der Fortsatz 21 gerade noch zwischen die Klemmstücke 28, 29 passt. Die stirnseitige Schmalfläche 51 des Füllkörpers 43 liegt an der Stirnseite des Fortsatzes 21 an oder ist im geringen Abstand zu diesem gehalten.In use, the filling body 43 fills the opening 23 so far that the extension 21 just barely fits between the clamping pieces 28, 29. The frontal narrow surface 51 of the filling body 43 abuts against the end face of the extension 21 or is held at a small distance therefrom.

Der Füllkörper 43 kann aus einem massiven Kunststoffmaterial, einem geschäumten Material oder ähnlichem bestehen. Er ist, zumindest geringfügig, flexibel nachgiebig, um eine geringe Federbewegung der Schenkel 26, 27 nicht zu behindern. Der Füllkörper 43 kann in der Öffnung 23 formschlüssig und gegebenenfalls unterstützend auch stoffschlüssig, z.B. durch Kleb- oder Haftstoff gesichert sein. Zusätzlich können sonstige Befestigungsmittel, wie z.B. Befestigungsclipse, Vorsprünge, Nasen und dergleichen vorgesehen sein.The packing 43 may be made of a solid plastic material, a foamed material or the like. He is, at least slightly, flexible yielding, not to hinder a slight spring movement of the legs 26, 27. The filling body 43 can also be positively closed in the opening 23 and, if necessary, also in a materially cohesive manner, e.g. be secured by adhesive or adhesive. In addition, other attachment means, such as e.g. Fixing clips, projections, noses and the like may be provided.

Eine weitere alternative Ausführungsform eines Schutzelements 52 ist in den Figuren 8 bis 10 veranschaulicht. Das Schutzelement 52 ist hier als Klebeelement ausgebildet. Es hat vorzugsweise die Form einer dünnen Platte gleichbleibender Dicke mit einer der Form der Öffnung 23 angepassten Kontur 53. Diese ist so bemessen, dass das Schutzelement 52 den Rand 32 der Öffnung 23 übergreift. Längsverlaufende Schlitze 54, 55 können vorgesehen sein, um seitlich über die Flachseiten 24, 25 vorstehende Partien der Klemmstücke 28, 29 aufzunehmen oder hindurchtreten zu lassen. Die Längen der zueinander parallel angeordneten Schlitze 54, 55 sind auf die Längen der Klemmstücke 28, 29 abgestimmt.Another alternative embodiment of a protective element 52 is shown in FIGS FIGS. 8 to 10 illustrated. The protective element 52 is designed here as an adhesive element. It preferably has the shape of a thin plate of constant thickness with a shape adapted to the shape of the opening 23 contour 53. This is dimensioned so that the protective element 52 engages over the edge 32 of the opening 23. Longitudinal slots 54, 55 may be provided to receive or pass laterally over the flat sides 24, 25 projecting portions of the clamping pieces 28, 29. The lengths of the mutually parallel Slots 54, 55 are matched to the lengths of the clamping pieces 28, 29.

Die Klebeelemente 52 können an einer der Flachseiten 24, 25 oder auch an beiden Flachseiten an dem Rand 32 der Öffnung 23 durch Klebstoff gesichert werden und permanent an dem Schaftstab 11 verbleiben. Es können bedarfsweise ein oder mehrere Webschäfte einer Fachbildeeinheit mit Schutzelementen einer oder mehrerer der vorgenannten Bauarten versehen sein. Insbesondere ist es empfehlenswert, die nach außen weisenden Flachseiten der außenständigen Webschäfte einer Fachbildeeinrichtung mit Schutzelementen der genannten Art zu versehen. Es wird so ein wirksamer Griffschutz gebildet. Ein hinreichender Griffschutz kann auch schon gegeben sein, wenn nur die im Gebrauch oberen Schaftstäbe mit Schutzelementen ausgestattet sind.The adhesive elements 52 can be secured on one of the flat sides 24, 25 or also on both flat sides on the edge 32 of the opening 23 by adhesive and remain permanently on the shaft rod 11. If necessary, one or more heald frames of a shedding unit can be provided with protective elements of one or more of the abovementioned types. In particular, it is advisable to provide the outwardly facing flat sides of the outer healds of a shedding device with protective elements of the type mentioned. It is thus formed an effective grip protection. A sufficient grip protection can already be given if only the upper shaft rods in use are equipped with protective elements.

Für die Eckverbinder 16 bis 19 eines Webschafts 10 einer Fachbildeeinheit sind Schutzelemente 31 vorgesehen, die den zwischen zwei Schenkeln 26, 27 gebildeten Freiraum abdecken und somit einen Griffschutz bilden.Protective elements 31 are provided for the corner connectors 16 to 19 of a heddle 10 of a shedding unit, which cover the clearance formed between two legs 26, 27 and thus form a grip protection.
