Definitions
- the invention relates to a knitting tool holder with a plurality of knitting tools, each of which has a working area, a fixing area and two narrow sides pointing in opposite directions, wherein the knitting tools are arranged parallel to each other and at a predetermined distance from each other between two cover boards.
- Such a tool holder is out DE 677 602 C known.
- the cover plates have grooves, in which the knitting tools can be inserted.
- a knitting tool holder In knitting machines, it is often customary to combine several knitting tools in a knitting tool holder.
- a knitting tool holder then often has a width of one or two inches and, depending on the fineness, a correspondingly large number of knitting tools.
- knitting tool here is a short name for those elements of a knitting machine, in particular a warp knitting machine, which are involved in the stitch formation in producing a knitted fabric. It is therefore not only the actual knitting tools, such as knitting needles, slides, sinkers and the like, but also to thread guide elements, such as hole needles, comb boards or the like.
- DE 196 18 368 B4 describes a knitting tool holder with a carrier having a groove.
- the groove is filled with a curable filling material, in which the knitting tools are used, as long as the filling compound is not yet cured.
- the invention has for its object to provide a knitting tool, which requires a small space with high rigidity.
- the knitting tools with the desired pitch are arranged side by side and positioned, for example in a corresponding teaching. You can then apply an adhesive on a narrow side of the knitting tools or on one side of a cover plate and then the cover plate stick with the knitting tools. The same process then repeats itself on the other narrow side. Of course, you can run both gluing at the same time. The result is a sandwich-like composite of the two cover plates and the knitting tools. The bonding of the knitting tools on the narrow sides is surprisingly sufficient to provide a knuckle tooling available that has a low mass and in any case after attachment of the knitting tool holder to the corresponding knitting tool bar sufficient rigidity.
- Each knitting tool preferably has a shank in the attachment area and the cover boards are glued to the shank. This creates a defined investment area for the cover plates on the knitting tools. This facilitates the production.
- the shaft has on at least one narrow side a projection which projects beyond an end face of the cover plate, wherein the projection has a contact surface which is glued to the end face.
- the projection may be formed so that it covers only a part of the thickness of the front side, so that a corresponding small adhesive surface is formed. But it can also be designed so large that the contact surface has an extension which is at least as large as the extension of the front side. In this case, the adhesive connection is made over the maximum possible area.
- the knitting tool is then held, so to speak, in two different directions in the knitting tool holder. Thereby results in an increased stability.
- the assembly is facilitated because the projection defines a position at which the cover plate can be brought to bear.
- the projection comprises the outside of the cover plate, wherein the projection on the outside of the cover plate is glued to the cover plate.
- the projection has a small groove which is slightly larger than the thickness of the cover plate. The cover plate is then inserted into this groove, so that the knitting tool, the cover plate in the region of the projection U-shaped surrounds.
- three adhesive surfaces between the knitting tool and the cover plate are available with each knitting tool, which results in a very high stability.
- a spacer is arranged between the cover plates, which has a thickness which corresponds to a distance between the narrow sides in the attachment region of the knitting tools.
- the cover plates are connected to the spacer, for example also by gluing.
- the cover plates are not only attached to the knitting tools, but also on the spacer on which the cover plates can create surface. This results in a very high stability of the active tool holder.
- the spacer ends at a side facing away from the working area end of the shaft.
- the area between knitting tools is therefore not filled by any additional parts or elements of the spacer.
- the spacer is made of a light metal or a plastic.
- the mass increase can be kept small by the spacer.
- the spacer forms at least one stop. If you mount the knitting tool holder on a knitting tool bar, then the stopper helps with the positioning.
- the stop is guided through a cover plate.
- the cover plate has the advantage that the spacer and the cover plates can still positively connect with each other, which further increases the stability of the active tool holder.
- the stop projects on the side facing away from the knitting tools from a space between the cover plates.
- the spacer can be designed with a simpler contour.
- the distance between the narrow sides is greater than the sum of the thicknesses of the cover boards.
- the size of the knitting tool holder can be kept very small.
- the cover plates contribute virtually nothing to a significant increase in size.
- the coversheets are formed of a sheet material having a thickness in the range of 0.1 to 0.8 mm.
- the cover plates can be practically designed as films. Although the coversheets are very thin, they can ensure sufficient stability due to the bond with the knitting tools.
- the sheet material steel or plastic optionally reinforced with fibers.
- the surface material only has to have sufficient tensile strength in order to be able to withstand the stresses during operation of the knitting machine.
- the knitting tools preferably protrude a maximum of 10 mm from the cover plates. Thus they have only a relatively short free length, in which they can be deformed. This keeps on the one hand the effort when reworking small, for example, when straightening knitting tools. On the other hand, the adhesive connection between the knitting tools and the cover plates is claimed only relatively low, because only a short lever arm is available.
- the active tool holder is constructed symmetrically to a plane between the cover plates. So you have to pay attention during assembly of the active tool holder no special orientation of the active tool holder against the knitting tool bar.
- Fig. 1 shows a knitting tool holder 1 with a plurality of knitting tools 2, which are arranged parallel to each other and at a predetermined distance 3 to each other. From the effect tools 2 you can in Fig. 1 only recognize a narrow side 4. If you have the in Fig. 1 Assigns visible narrow side 4 a front, then there is a corresponding narrow side 5 at the back. The narrow sides 4, 5 thus have in opposite directions.
- the knitting tools 2 which are present here in the form of hole needles, flat. You can for example be punched from a sheet of appropriate thickness.
- the knitting tool holder has two holes 6, 7, can be guided by the screws with which the knitting tool holder 1 can be attached to a knitting tool not shown.
- the knitting tool holder 1 has a width of, for example, 1 or 2 inches. Since it is possible to arrange the holes 6, 7 relatively far apart from one another, this results in a good alignment possibility of the knitting tool holder 1 on the knitting tool bar.
- the knitting tool holder 1 is formed like a sandwich.
- a first cover plate 8 is glued to the front narrow side 4 of the knitting tool 2.
- a second cover plate 9 is glued to the narrow side 5 at the back of the knitting tool 2.
- the terms "front” and “back” are used here only to facilitate the explanation.
- the knitting tool holder 1 is formed symmetrically to a plane between the two cover plates 8, 9, so it can in the illustrated orientation or in a direction offset by 180 ° to be mounted.
- the knitting tool 2 has a working area 10 and a fastening area, which is formed here by a shaft 11.
- the cover plates 8, 9 are glued only in the region of the shaft 11 with the knitting tool 2.
- an adhesive 12 between the shaft 11 and the cover plates 8, 9 is arranged in each case.
- the spacer 13 has a thickness which corresponds to the distance between the two narrow sides 4, 5 in the region of the shank 11, that is to say in the fastening region. Accordingly, the two cover plates 8, 9 may be flat over their entire extent.
- the cover plates 8, 9 are connected to the spacer 13 surface, for example by gluing. But they can also be point or line connected to the spacer 13.
- the cover plates 8, 9 are formed of a relatively thin sheet material.
- they may be formed as steel foils having a thickness between the range of 0.1 to 0.8 mm, preferably in the range of 0.1 to 0.5 mm.
- Both steel and fiber-reinforced plastics have a relatively high tensile strength, so that the adhesive bond between the end faces 4, 5 and the cover plates 8, 9 is sufficient to keep the knitting tools 2 reliably in position.
- the spacer 13 may also be formed of a plastic. You can also use a light metal. Of course, the holes 6, 7 also penetrate the spacer 13.
- the spacer 13 has a pair of stops 14, 15, that is to say a stop 14 on the front side and a stop 15 on the rear side. Another pair of stops, of which only one stop 16 can be seen on the front, can be provided in the region of the other edge of the knitting tool holder 1.
- the stops 14, 15 are guided through corresponding openings 17, 18 in the cover plates 8, 9. They cause a positive connection between the spacer 13 and the cover plates 8, 9th
- the spacer 13 has at its the knitting tools 2 edge facing no profile, but it is smooth. In particular, there are no elements or projections of the spacer 13, which protrude into the interstices 3 between the knitting tools 2. These gaps 3 are between the cover plates 8, 9 free.
- the stops 14, 15 can be used as an aid to position the knitting tool holder 1 on the knitting tool bar.
- Fig. 2 It is shown that the adhesive 12 protrudes slightly beyond the knitting tool 2 inwardly between the cover plates 8, 9. This will come in many cases can not be avoided, but is not necessary in principle.
- Fig. 3 shows a modified embodiment, which differs from that of Fig. 1 and 2 differs in that the spacer 13 has stops 19, 20 which protrude on the side facing away from the knitting tools from a space between the cover plates 8, 9.
- the knitting tool holder 1 after Fig. 3 also has a material recess 21 which is used for mass reduction.
- Fig. 4 shows a side view of the knitting tool holder 1 Fig. 3 ,
- Fig. 5 shows a modification of the knitting tool holder 1 after Fig. 4 ,
- the knitting tool 2 has at its the work area 10 facing the end of the shaft 11 at the Front 4 a projection 22 and on the back 5 a projection 23.
- the projections 22, 23 each form a contact surface 24, 25.
- the contact surface 24, 25 has an extension in a direction from the front 4 to the back 5, which is greater than the thickness of the cover plates 8, 9.
- Knitting tool 2 also in the area of the contact surfaces 24, 25 with end faces of the cover plates 8, 9 to glue. This results in an adhesive connection in two different directions, namely once along the longitudinal extent of the knitting tools 2 and once across it. This results in increased strength and thus improved rigidity.
- Fig. 6 shows one opposite Fig. 5 modified embodiment of a knitting tool holder 1 in side view.
- the projections 22, 23 of the knitting tool 2 each have a groove 26, 27, so that the projections 22, 23 can cover the cover plates 8, 9 in a U-shape.
- These grooves 26, 27 are formed so that the cover plates 8, 9 can be inserted with little play. This game is so large that you can still accommodate an adhesive between the cover plates 8, 9 and the walls of the grooves 26, 27, so that the knitting tool 2 with the cover plates 8, 9 along the walls of the groove 26, 27 can be glued ,
- the cover plates 8, 9 are, as stated above, very thin.
- the distance between the narrow sides 4, 5 in the mounting area, ie on the shaft 11, is greater than the sum of the thicknesses of the cover plates 8, 9. Accordingly the thickness of the knitting tool holder 1 is determined mainly by the width of the knitting tools.
- the cover plates 8, 9 hardly contribute to the thickness.
- the cover plates 8, 9 are not thicker than the knitting tools. 2
- the knitting tools 2 are at most 10 mm from the cover plates 8, 9 before, preferably even only 5 mm or less. This results in a relatively short free lever arm on the knitting tools 2, so that moments that could lead to a loosening of the adhesive bond between the knitting tools 2 and the cover plates 8, 9, also can be kept small. In addition, the risk of deformation of the knitting tools 2 and the associated need for alignment of the knitting tools 2 is small.

Description
Die Erfindung betrifft eine Wirkwerkzeugfassung mit mehreren Wirkwerkzeugen, von denen jedes einen Arbeitsbereich, einen Befestigungsbereich und zwei in entgegen gesetzte Richtungen weisende Schmalseiten aufweist, wobei die Wirkwerkzeuge parallel nebeneinander und mit vorbestimmtem Abstand zueinander zwischen zwei Deckplatinen angeordnet sind.The invention relates to a knitting tool holder with a plurality of knitting tools, each of which has a working area, a fixing area and two narrow sides pointing in opposite directions, wherein the knitting tools are arranged parallel to each other and at a predetermined distance from each other between two cover boards.
Eine derartige Wirkwerkzeugfassung ist aus
In Wirkmaschinen ist es vielfach üblich, mehrere Wirkwerkzeuge in einer Wirkwerkzeugfassung zusammenzufassen. Eine Wirkwerkzeugfassung hat dann vielfach eine Breite von ein oder zwei Zoll und nimmt in Abhängigkeit von der Feinheit eine entsprechend große Anzahl von Wirkwerkzeugen auf.In knitting machines, it is often customary to combine several knitting tools in a knitting tool holder. A knitting tool holder then often has a width of one or two inches and, depending on the fineness, a correspondingly large number of knitting tools.
Der Begriff "Wirkwerkzeug" ist hier eine Kurzbezeichnung für diejenigen Elemente einer Wirkmaschine, insbesondere einer Kettenwirkmaschine, die an der Maschenbildung beim Herstellen einer Wirkware beteiligt sind. Es handelt sich also nicht nur um die eigentlichen Wirkwerkzeuge, wie Wirknadeln, Schieber, Platinen und dergleichen, sondern auch um Fadenführungselemente, wie Lochnadeln, Kammplatinen oder dergleichen.The term "knitting tool" here is a short name for those elements of a knitting machine, in particular a warp knitting machine, which are involved in the stitch formation in producing a knitted fabric. It is therefore not only the actual knitting tools, such as knitting needles, slides, sinkers and the like, but also to thread guide elements, such as hole needles, comb boards or the like.
Wenn man mehrere Wirkwerkzeuge in einer Fassung zu einer Gruppe zusammenfasst, können sie an der Wirkmaschine schneller montiert und eingestellt werden.If you combine several knitting tools in one version into a group, they can be mounted and adjusted faster on the knitting machine.
Ursprünglich hatte man zum Herstellen von Fassungen die Wirkwerkzeuge in Blei eingegossen. Dies hat den Nachteil, dass damit eine große Masse verbunden ist, die sich ungünstig auf die Arbeitsgeschwindigkeit der Wirkmaschine auswirkt. Auch können die beim Gießen auftretenden Temperaturen die Wirkwerkzeuge verformen, was ein aufwändiges Nacharbeiten der Wirkwerkzeugfassung erforderlich macht.Originally, the knives had been cast in lead to make frames. This has the disadvantage that it is connected to a large mass, which adversely affects the working speed of the knitting machine. Also, the temperatures occurring during casting can deform the knitting tools, which requires a complex reworking of the knuckle tool holder.
Man hat in
Bei schnell laufenden Maschinen müssen nicht nur die Wirkwerkzeugbarren, sondern auch die Wirkwerkzeugfassungen eine hohe Steifigkeit und eine ausreichende Festigkeit aufweisen. Dies bedingt bei der Verwendung von aus Gewichtsgründen bevorzugtem Kunststoff oder Leichtmetall eine relativ große Wandstärke der Wirkwerkzeugfassung. Dies wiederum hat eine erhöhte Masse zur Folge, was nicht erwünscht ist. Darüber hinaus wird man beispielsweise bei Legenadeln in der Wahl der Fadenführung eingeschränkt, weil die Fäden nicht mit der Wirkwerkzeugfassung kollidieren dürfen.In high-speed machines not only the knitting tool bars, but also the knuckle holders must have a high rigidity and sufficient strength. This requires in the use of preferred weight reasons plastic or light metal, a relatively large wall thickness of the knitting tool holder. This in turn results in an increased mass, which is undesirable. In addition, it is restricted, for example in guide needles in the choice of thread guide, because the threads must not collide with the knitting tool holder.
Der Erfindung liegt die Aufgabe zugrunde, eine Wirkwerkzeugfassung anzugeben, die bei großer Steifigkeit einen geringen Bauraum benötigt.The invention has for its object to provide a knitting tool, which requires a small space with high rigidity.
Diese Aufgabe wird bei einer Wirkwerkzeugfassung der eingangs genannten Art dadurch gelöst, dass die Schmalseiten der Wirkwerkzeuge mit den Deckplatinen verklebt sind.This object is achieved in a knitting tool holder of the type mentioned above in that the narrow sides of the knitting tools are glued to the cover plates.
Mit dieser Ausgestaltung benötigt man für die Verbindung der Wirkwerkzeuge mit der Wirkwerkzeugfassung nur eine geringe Menge an Klebstoff. Diese Menge muss lediglich eine Verbindung zwischen den Schmalseiten der Wirkwerkzeuge und den Deckplatinen herstellen. Bei der Montage werden also die Wirkwerkzeuge mit der gewünschten Teilung nebeneinander angeordnet und beispielsweise in einer entsprechenden Lehre positioniert. Man kann dann einen Klebstoff auf eine Schmalseite der Wirkwerkzeuge oder auf eine Seite einer Deckplatine auftragen und dann die Deckplatine mit den Wirkwerkzeugen verkleben. Der gleiche Vorgang wiederholt sich dann bei der anderen Schmalseite. Selbstverständlich kann man beide Klebevorgänge auch gleichzeitig ablaufen lassen. Es entsteht dann ein sandwichartiger Verbund aus den beiden Deckplatinen und den Wirkwerkzeugen. Die Verklebung der Wirkwerkzeuge an den Schmalseiten reicht erstaunlicherweise aus, um eine Wirkwerkzeugfassung zur Verfügung zu stellen, die eine geringe Masse und jedenfalls nach der Befestigung der Wirkwerkzeugfassung an der entsprechenden Wirkwerkzeugbarre eine ausreichende Steifigkeit aufweist.With this configuration, one needs only a small amount of adhesive for the connection of the knitting tools with the knitting tool holder. This amount only has to establish a connection between the narrow sides of the knitting tools and the cover plates. During assembly, therefore, the knitting tools with the desired pitch are arranged side by side and positioned, for example in a corresponding teaching. You can then apply an adhesive on a narrow side of the knitting tools or on one side of a cover plate and then the cover plate stick with the knitting tools. The same process then repeats itself on the other narrow side. Of course, you can run both gluing at the same time. The result is a sandwich-like composite of the two cover plates and the knitting tools. The bonding of the knitting tools on the narrow sides is surprisingly sufficient to provide a knuckle tooling available that has a low mass and in any case after attachment of the knitting tool holder to the corresponding knitting tool bar sufficient rigidity.
Vorzugsweise weist jedes Wirkwerkzeug im Befestigungsbereich einen Schaft auf und die Deckplatinen sind mit dem Schaft verklebt. Damit wird an den Wirkwerkzeugen ein definierter Anlagebereich für die Deckplatinen geschaffen. Dies erleichtert die Fertigung.Each knitting tool preferably has a shank in the attachment area and the cover boards are glued to the shank. This creates a defined investment area for the cover plates on the knitting tools. This facilitates the production.
Vorzugsweise weist der Schaft an mindestens einer Schmalseite einen Vorsprung auf, der über eine Stirnseite der Deckplatine vorsteht, wobei der Vorsprung eine Anlagefläche aufweist, die mit der Stirnseite verklebt ist. Der Vorsprung kann so ausgebildet sein, dass er nur einen Teil der Dicke der Stirnseite überdeckt, so dass eine entsprechende geringe Klebefläche entsteht. Er kann aber auch so groß ausgebildet sein, dass die Anlagefläche eine Erstreckung aufweist, die mindestens so groß ist wie die Erstreckung der Stirnseite. In diesem Fall erfolgt die Klebeverbindung über die maximal mögliche Fläche. Das Wirkwerkzeug wird dann sozusagen in zwei unterschiedlichen Richtungen in der Wirkwerkzeugfassung gehalten. Dadurch ergibt sich eine erhöhte Stabilität. Darüber hinaus wird die Montage erleichtert, weil der Vorsprung eine Position definiert, an der die Deckplatine zur Anlage gebracht werden kann.Preferably, the shaft has on at least one narrow side a projection which projects beyond an end face of the cover plate, wherein the projection has a contact surface which is glued to the end face. The projection may be formed so that it covers only a part of the thickness of the front side, so that a corresponding small adhesive surface is formed. But it can also be designed so large that the contact surface has an extension which is at least as large as the extension of the front side. In this case, the adhesive connection is made over the maximum possible area. The knitting tool is then held, so to speak, in two different directions in the knitting tool holder. Thereby results in an increased stability. In addition, the assembly is facilitated because the projection defines a position at which the cover plate can be brought to bear.
Vorzugsweise umfasst der Vorsprung die Deckplatine außen, wobei der Vorsprung auf der Außenseite der Deckplatine mit der Deckplatine verklebt ist. Mit anderen Worten weist der Vorsprung eine kleine Nut auf, die geringfügig größer ist als die Dicke der Deckplatine. Die Deckplatine wird dann in diese Nut eingeführt, so dass das Wirkwerkzeug die Deckplatine im Bereich des Vorsprungs U-förmig umgreift. Damit stehen bei jedem Wirkwerkzeug drei Klebeflächen zwischen dem Wirkwerkzeug und der Deckplatine zur Verfügung, was eine sehr hohe Stabilität ergibt.Preferably, the projection comprises the outside of the cover plate, wherein the projection on the outside of the cover plate is glued to the cover plate. In other words, the projection has a small groove which is slightly larger than the thickness of the cover plate. The cover plate is then inserted into this groove, so that the knitting tool, the cover plate in the region of the projection U-shaped surrounds. Thus, three adhesive surfaces between the knitting tool and the cover plate are available with each knitting tool, which results in a very high stability.
Bevorzugterweise ist zwischen den Deckplatinen ein Distanzstück angeordnet, das eine Dicke aufweist, die einem Abstand zwischen den Schmalseiten im Befestigungsbereich der Wirkwerkzeuge entspricht. Die Deckplatinen sind mit dem Distanzstück verbunden, beispielsweise ebenfalls durch Kleben. Damit sind die Deckplatinen nicht nur an den Wirkwerkzeugen befestigt, sondern auch noch am Distanzstück, an dem sich die Deckplatinen flächig anlegen können. Dies ergibt eine sehr hohe Stabilität der Wirkwerkzeugfassung.Preferably, a spacer is arranged between the cover plates, which has a thickness which corresponds to a distance between the narrow sides in the attachment region of the knitting tools. The cover plates are connected to the spacer, for example also by gluing. Thus, the cover plates are not only attached to the knitting tools, but also on the spacer on which the cover plates can create surface. This results in a very high stability of the active tool holder.
Bevorzugterweise endet das Distanzstück an einem vom Arbeitsbereich abgewandten Ende des Schafts. Der Bereich zwischen Wirkwerkzeugen wird also nicht durch irgendwelche Zusatzteile oder Elemente des Distanzstücks ausgefüllt. Insbesondere bei hohen Feinheiten der Wirkwerkzeuge ist es wesentlich einfacher, das Distanzstück mit einer nicht profilierten Seitenkante zu versehen, die nicht in einem Zwischenraum zwischen den Wirkwerkzeugen vorsteht.Preferably, the spacer ends at a side facing away from the working area end of the shaft. The area between knitting tools is therefore not filled by any additional parts or elements of the spacer. In particular, with high finenesses of the knitting tools, it is much easier to provide the spacer with a non-profiled side edge, which does not protrude in a space between the knitting tools.
Bevorzugterweise ist das Distanzstück aus einem Leichtmetall oder aus einem Kunststoff gebildet. Damit lässt sich die Massenvergrößerung durch das Distanzstück klein halten.Preferably, the spacer is made of a light metal or a plastic. Thus, the mass increase can be kept small by the spacer.
Vorzugsweise bildet das Distanzstück mindestens einen Anschlag. Wenn man die Wirkwerkzeugfassung an einer Wirkwerkzeugbarre montiert, dann hilft der Anschlag bei der Positionierung.Preferably, the spacer forms at least one stop. If you mount the knitting tool holder on a knitting tool bar, then the stopper helps with the positioning.
In einer ersten bevorzugten Ausgestaltung ist vorgesehen, dass der Anschlag durch eine Deckplatte hindurchgeführt ist. In diesem Fall ist es zwar erforderlich, die Deckplatte mit einer entsprechenden Öffnung zu versehen. Die Ausgestaltung hat aber den Vorteil, dass man das Distanzstück und die Deckplatinen auch noch formschlüssig miteinander verbinden kann, was die Stabilität der Wirkwerkzeugfassung weiter erhöht.In a first preferred embodiment, it is provided that the stop is guided through a cover plate. In this case, although it is necessary to provide the cover plate with a corresponding opening. However, the design has the advantage that the spacer and the cover plates can still positively connect with each other, which further increases the stability of the active tool holder.
In einer zweiten bevorzugten Ausgestaltung steht der Anschlag auf der den Wirkwerkzeugen abgewandten Seite aus einem Raum zwischen den Deckplatinen vor. In diesem Fall kann das Distanzstück mit einer einfacheren Kontur gestaltet werden.In a second preferred embodiment, the stop projects on the side facing away from the knitting tools from a space between the cover plates. In this case, the spacer can be designed with a simpler contour.
Vorzugsweise ist im Befestigungsbereich der Abstand zwischen den Schmalseiten größer als die Summe der Dicken der Deckplatinen. Damit kann die Baugröße der Wirkwerkzeugfassung sehr klein gehalten werden. Die Deckplatinen tragen praktisch nichts zu einer nennenswerten Vergrößerung der Baugröße bei.Preferably, in the attachment area, the distance between the narrow sides is greater than the sum of the thicknesses of the cover boards. Thus, the size of the knitting tool holder can be kept very small. The cover plates contribute virtually nothing to a significant increase in size.
Vorzugsweise sind die Deckplatinen aus einem Flächenmaterial mit einer Dicke im Bereich von 0,1 bis 0,8 mm gebildet. Die Deckplatinen können praktisch als Folien ausgebildet sein. Obwohl die Deckplatinen sehr dünn sind, können sie aufgrund der Klebverbindung mit den Wirkwerkzeugen eine ausreichende Stabilität sicherstellen.Preferably, the coversheets are formed of a sheet material having a thickness in the range of 0.1 to 0.8 mm. The cover plates can be practically designed as films. Although the coversheets are very thin, they can ensure sufficient stability due to the bond with the knitting tools.
Hierbei ist bevorzugt, dass das Flächenmaterial Stahl oder Kunststoff, gegebenenfalls mit Fasern verstärkt ist. Das Flächenmaterial muss lediglich eine ausreichende Zugfestigkeit aufweisen, um den Beanspruchungen beim Betrieb der Wirkmaschine widerstehen zu können.It is preferred that the sheet material steel or plastic, optionally reinforced with fibers. The surface material only has to have sufficient tensile strength in order to be able to withstand the stresses during operation of the knitting machine.
Vorzugsweise stehen die Wirkwerkzeuge maximal 10 mm aus den Deckplatinen vor. Damit haben sie nur eine relativ kurze freie Länge, in der sie verformt werden können. Dies hält zum einen den Aufwand beim Nacharbeiten klein, beispielsweise beim Richten der Wirkwerkzeuge. Zum anderen wird auch die Klebeverbindung zwischen den Wirkwerkzeugen und den Deckplatinen nur relativ gering beansprucht, weil nur ein kurzer Hebelarm zur Verfügung steht.The knitting tools preferably protrude a maximum of 10 mm from the cover plates. Thus they have only a relatively short free length, in which they can be deformed. This keeps on the one hand the effort when reworking small, for example, when straightening knitting tools. On the other hand, the adhesive connection between the knitting tools and the cover plates is claimed only relatively low, because only a short lever arm is available.
Bevorzugterweise ist die Wirkwerkzeugfassung symmetrisch zu einer Ebene zwischen den Deckplatinen aufgebaut. Man muss also bei der Montage der Wirkwerkzeugfassung keine besondere Orientierung der Wirkwerkzeugfassung gegenüber der Wirkwerkzeugbarre beachten.Preferably, the active tool holder is constructed symmetrically to a plane between the cover plates. So you have to pay attention during assembly of the active tool holder no special orientation of the active tool holder against the knitting tool bar.

Zwischen den beiden Deckplatinen 8, 9 ist ferner ein Distanzstück 13 angeordnet. Das Distanzstück 13 hat eine Dicke, die dem Abstand zwischen den beiden Schmalseiten 4, 5 im Bereich des Schaftes 11, also im Befestigungsbereich, entspricht. Dementsprechend können die beiden Deckplatinen 8, 9 über ihre gesamte Erstreckung eben ausgebildet sein. Die Deckplatinen 8, 9 sind mit dem Distanzstück 13 flächig verbunden, beispielsweise durch Kleben. Sie können aber auch punkt- oder linienweise mit dem Distanzstück 13 verbunden sein.Between the two
Die Deckplatinen 8, 9 sind aus einem relativ dünnen Flächenmaterial gebildet. Sie können beispielsweise als Stahlfolien mit einer Dicke zwischen dem Bereich von 0,1 bis 0,8 mm ausgebildet sein, vorzugsweise im Bereich von 0,1 bis 0,5 mm. Alternativ kann man auch einen Kunststoff für die Deckplatinen 8, 9 verwenden, wobei der Kunststoff vorzugsweise mit Fasern verstärkt ist, beispielsweise Glas- oder Kohlefasern. Sowohl Stahl als auch faserverstärkte Kunststoffe haben eine relativ hohe Zugfestigkeit, so dass die Klebeverbindung zwischen den Stirnseiten 4, 5 und den Deckplatinen 8, 9 ausreicht, um die Wirkwerkzeuge 2 zuverlässig in der Position zu halten.The
Das Distanzstück 13 kann ebenfalls aus einem Kunststoff gebildet sein. Man kann auch ein Leichtmetall verwenden. Die Löcher 6, 7 durchdringen natürlich auch das Distanzstück 13.The
Bei der Ausgestaltung nach
Das Distanzstück 13 weist an seinem den Wirkwerkzeugen 2 zugewandten Rand kein Profil auf, sondern es ist glatt. Insbesondere gibt es keine Elemente oder Vorsprünge des Distanzstücks 13, die in die Zwischenräume 3 zwischen den Wirkwerkzeugen 2 ragen. Diese Zwischenräume 3 sind zwischen den Deckplatinen 8, 9 frei. Die Anschläge 14, 15 können als Hilfsmittel verwendet werden, um die Wirkwerkzeugfassung 1 an der Wirkwerkzeugbarre zu positionieren.The
In
Die Wirkwerkzeugfassung 1 nach
Es ist zu erkennen, dass die Vorsprünge 22, 23 des Wirkwerkzeugs 2 jeweils eine Nut 26, 27 aufweisen, so dass die Vorsprünge 22, 23 die Deckplatinen 8, 9 U-förmig umgreifen können. Diese Nuten 26, 27 sind so ausgebildet, dass die Deckplatinen 8, 9 mit geringem Spiel eingeführt werden können. Dieses Spiel ist so groß, dass man noch einen Klebstoff zwischen den Deckplatinen 8, 9 und den Wänden der Nuten 26, 27 unterbringen kann, so dass das Wirkwerkzeug 2 mit den Deckplatinen 8, 9 entlang der Wände der Nut 26, 27 verklebt werden kann.It can be seen that the
Die Deckplatinen 8, 9 sind, wie oben ausgeführt, sehr dünn. Der Abstand zwischen den Schmalseiten 4, 5 im Befestigungsbereich, also am Schaft 11, ist größer als die Summe der Dicken der Deckplatinen 8, 9. Dementsprechend wird die Dicke der Wirkwerkzeugfassung 1 hauptsächlich durch die Breite der Wirkwerkzeuge bestimmt. Die Deckplatinen 8, 9 tragen kaum zur Dicke bei. Die Deckplatinen 8, 9 sind nicht dicker als die Wirkwerkzeuge 2.The
Die Wirkwerkzeuge 2 stehen maximal 10 mm aus den Deckplatinen 8, 9 vor, vorzugsweise sogar nur 5 mm oder weniger. Damit ergibt sich ein relativ kurzer freier Hebelarm an den Wirkwerkzeugen 2, so dass Momente, die zu einem Lösen der Klebeverbindung zwischen den Wirkwerkzeugen 2 und den Deckplatinen 8, 9 führen könnten, ebenfalls klein gehalten werden können. Darüber hinaus ist die Gefahr einer Verformung der Wirkwerkzeuge 2 und die damit verbundene Notwendigkeit einer Ausrichtung der Wirkwerkzeuge 2 klein.The
