Description

Die Erfindung betrifft eine Kardierplatte gemäß dem Oberbegriff des Anspruches 1.The invention relates to a carding plate according to the preamble of claim 1.

Unter einer Karde ist jede Art einer Karde verstanden, die mindestens eine Kardierplatte nach der Erfindung erhalten kann, wie Wanderdeckelkarde, Krempel usw.A card is understood to mean any type of card that can have at least one carding plate according to the invention, such as revolving card, card, etc.

Eine Kardierplatte, auf die sich die Erfindung bezieht, kann an der Karde unbeweglich angeordnet sein oder auch einen stabförmigen Deckel des Wanderdeckels einer Wanderdeckelkarde bilden. Bei unbeweglicher Anordnung der Kardierplatte kann diese im allgemeinen zweckmäßig zwischen Vorreisser und Wanderdeckel od. dergl. angeordnet sein oder auch zwischen dem Wanderdeckel od. dergl. und dem Abnehmer oder in manchen Fällen auch unterhalb des Tambours der Karde zwischen Abnehmer und Vorreisser oder je nach Karde an sonstiger geeigneter Stelle.A carding plate, to which the invention relates, can be arranged immovably on the card or can also form a rod-shaped cover of the revolving cover of a revolving card. In the case of an immovable arrangement of the carding plate, this can generally be expediently arranged between the licker-in and revolving cover or the like, or also between the revolving cover or the like and the customer, or in some cases also below the reel of the card between the customer and liner or, depending on the card elsewhere.

Eine Kardierplatte, auf die sich die Erfindung bezieht, wird an der Karde so angeordnet, daß sie sich bezüglich ihrer Längsrichtung parallel zur Drehachse des Tambours erstreckt. Das Zahnfeld der Kardierplatte erstreckt sich dann ungefähr über die in Richtung der Drehachse des Tambours gemessene Breite seines Beschlages, d. h. die Arbeitsbreite des Tambours. Unter dem Beschlag des Tambours ist seine Häkchen oder Zähne aufweisende Garnitur verstanden.A carding plate, to which the invention relates, is arranged on the card so that its longitudinal direction extends parallel to the axis of rotation of the spool. The tooth field of the carding plate then extends approximately over the width of its fitting measured in the direction of the axis of rotation of the drum, i. H. the working width of the drum. The fitting of the drum is understood to be its hook or teeth set.

An einer Karde können eine Kardierplatte oder eine Mehrzahl von Kardierplatten, auf die sich die Erfindung bezieht, angeordnet sein.A carding plate or a plurality of carding plates to which the invention relates can be arranged on a card.

Bei der Kardierplatte, auf die sich die Erfindung bezieht, handelt es sich also nicht um eine rotierende Walze der Karde, sondern um eine Kardierplatte, die nicht rotiert. Sie wird an der Karde unbeweglich angeordnet oder ist ein langsam wandernder Deckel des Wanderdeckels einer Wanderdeckelkarde.The carding plate to which the invention relates is therefore not a rotating roller of the card, but a carding plate that does not rotate. It is arranged immovably on the card or is a slowly moving cover of the moving cover of a moving card.

Um die Scheibenreihe, die ein Zahnfeld einer Kardierplatte bekannter Art bildet, am Träger zu befestigen, ist es bekannt, die Scheiben an ihren Längsenden mit Schultern zu versehen und sie am Träger mittels U-förmigen Clips oder Z-förmigen Haltewinkeln zu befestigen, wobei jeder solcher Clips oder Haltewinkel mit einem Außenschenkel auf einem durch Schultern der Scheiben gebildeten Absatz der Scheibenreihe aufliegt und mit seinem anderen Außenschenkel am Träger befestigt ist (vgl. beispielsweise GB-A-2100 305). Diese Befestigung der Scheiben verringert jedoch schon wegen der Schultern der Zahnscheiben die Arbeitsbreite des Zahnfeldes und beeinträchtigt damit die Kardierarbeit. Auch ist die Anbringung einer Scheibenreihe am Träger zeitaufwendig und macht nach dem Anbringen der Clipse bzw. Haltewinkel stets eine nachträglich genaue Justierung der Scheiben auf dem Träger und Nachschleifen der Zähne des Zahnfeldes erforderlich. Auch ist das Auswechseln der Scheiben eines solchen Zahnfeldes gegen neue Scheiben zeitraubend.In order to attach the row of disks, which forms a tooth field of a carding plate of known type, to the carrier, it is known to provide the disks with shoulders at their longitudinal ends and to attach them to the carrier by means of U-shaped clips or Z-shaped brackets, each such clips or brackets with one outer leg rests on a shoulder of the row of panes formed by shoulders of the panes and is attached to the carrier with its other outer leg (cf. for example GB-A-2100 305). However, this fastening of the disks already reduces the working width of the tooth field because of the shoulders of the toothed disks and thus impairs the carding work. The attachment of a row of disks to the carrier is also time-consuming and always requires subsequent precise adjustment of the disks on the carrier and regrinding of the teeth of the tooth field after the clips or holding brackets have been attached. Also, replacing the washers of such a tooth field with new washers is time-consuming.

Es ist eine Aufgabe der Erfindung, eine Kardierplatte der eingangs genannten Art zu schaffen, welche rasche, einfache Montage der Scheiben der Scheibenreihe am Träger möglichst ohne Verlust an Arbeitsbreite des Zahnfeldes ermöglicht.It is an object of the invention to provide a carding plate of the type mentioned at the outset which enables the disks of the row of disks to be mounted on the carrier quickly and easily, as far as possible without loss of the working width of the tooth field.

Diese Aufgabe wird erfindungsgemäß durch eine Kardierplatte gemäß Patentanspruch 1 gelöst.This object is achieved by a carding plate according to claim 1.

Durch die Zusammenfassung der Scheiben eines Zahnfeldes zu einem Paket oder mehreren miteinander fluchtenden, abstandslos hintereinander angeordneten Paketen, wobei das einzelne Paket in sich durch die mindestens eine Spannvorrichtung zusammengehalten ist und durch in den zweiten Kanal oder die zweiten Kanäle des Paketes eingreifende Aufspannmittel auf dem Träger aufgespannt ist, geht keine Breite dieses Zahnfeldes durch die Aufspannmittel verloren, so daß am Träger ein über seine Breite reichendes Zahnfeld oder eine Mehrzahl von hintereinander angeordneten Zahnfeldern vorgesehen sein können, wodurch bei gegebener Breite des Trägers die Kardierarbeit verbessert wird.By combining the slices of a tooth field into a package or a plurality of packages that are aligned with one another and spaced one behind the other, the individual package being held together by the at least one clamping device and by means of clamping means on the carrier that engage in the second channel or the second channels of the package is stretched, no width of this tooth field is lost by the clamping means, so that a tooth field extending over its width or a plurality of tooth fields arranged one behind the other can be provided on the carrier, thereby improving the carding work for a given width of the carrier.

Bei mehreren Zahnfeldern ist es insbesondere auch möglich, diese abstandslos in Rotationsrichtung des Tambours der Karde aneinander anschließen zu lassen. Dies ist insbesondere bei einer unbeweglich an der Karde anzuordnenden Kardierplatte zweckmäßig, da hierdurch die Kardierarbeit noch weiter verbessert, die Staubentwicklung beim Kardieren verringert, die Gefahr von Faserstauungen ebenfalls verringert oder ganz behoben wird und man kann auf eine sonst in vielen Fällen notwendige Staubabsaugung ohne Nachteil verzichten. Und zwar ging man bisher bei Hintereinanderanordnung mehrerer unbeweglicher Zahnfelder so vor, eine der Anzahl der Zahnfelder entsprechende Anzahl von Kardierplatten, von denen also jede ein einziges Zahnfeld aufwies, hintereinander anzuordnen. Durch die Zwischenräume zwischen den Kardierplatten entstanden hier jedoch starke Luftströme, die starke Staubentwicklung verursachten und die Kardierarbeit beeinträchtigten.In the case of a plurality of tooth fields, it is in particular also possible to have them connected to one another in the rotational direction of the reel of the card. This is particularly expedient in the case of a carding plate which can be immovably arranged on the card, since this further improves the carding work, reduces the dust development during carding, the risk of fiber congestion is also reduced or completely eliminated, and dust extraction, which is otherwise necessary in many cases, can be done without disadvantage dispense. In fact, in the past, when several immovable tooth fields were arranged one after the other, a number of carding plates corresponding to the number of tooth fields, each of which had a single tooth field, was arranged one behind the other. However, the gaps between the carding plates created strong air currents, which caused a lot of dust and impaired the carding work.

Bei einer Mehrzahl von Zahnfeldern der Kardierplatte kann vorteilhaft vorgesehen sein, daß sich die sie bildenden Scheibenreihen insbesondere berühren oder zum Ausgleich von Fertigungstoleranzen und leichterem Verschieben der Scheibenreihen in Längsrichtung relativ zueinander sich fast berühren.In the case of a plurality of tooth fields of the carding plate, it can advantageously be provided that the rows of disks forming them touch each other or almost touch each other to compensate for manufacturing tolerances and easier displacement of the rows of disks in the longitudinal direction.

Indem die Scheiben eines Paketes durch die mindestens eine Spannvorrichtung schon vor dem Aufbringen auf den Träger zusammengehalten sind, können sie zu dem Paket bereits im Herstellerwerk verbunden werden, was hohe Präzision problemlos möglich macht. Auf dem Träger kann das Paket dann bespw. erst in der Spinnerei befestigt werden. Auch ermöglicht dieses Zusammenfassen der Scheiben zu einem oder mehreren, je eine Baueinheit bildenden Paketen leichtes, rasches und problemloses Auswechseln der Scheiben eines Paketes gegen neue Scheiben, indem ein entsprechendes Paket neuer Scheiben gegen das alte Paket ausgewechselt wird. Häufig kommt es vor, daß nur ein begrenzter Abschnitt einer Scheibenreihe auszuwechselnde Scheiben aufweist und die übrigen Scheiben dieser Scheibenreihe noch voll funktionsfähig sind, also nicht ausgewechselt werden müssen. Um hier das Auswechseln zu verbilligen und zu vereinfachen, kann vorgesehen sein, daß die Scheibenreihe durch mehrere miteinander fluchtende Pakete gebildet ist. Im Falle des Auswechselns eines begrenzten Bereiches der Scheiben der Scheibenreihe genügt es dann im allgemeinen, nur ein oder zwei dieser Pakete auszuwechseln und die restlichen Pakete nicht auszuwechseln.Because the panes of a package are held together by the at least one tensioning device before they are applied to the carrier, they can already be connected to the package in the manufacturing plant, which makes high precision possible without problems. The package can then be carried on the carrier. only be fastened in the spinning mill. This combination of the disks into one or more packages, each forming a structural unit, enables easy, quick and easy replacement of the Disks of a package against new disks by exchanging a corresponding package of new disks for the old package. It often happens that only a limited section of a row of disks has disks to be replaced and the remaining disks of this row of disks are still fully functional, ie do not have to be replaced. In order to reduce the cost and simplify the replacement, it can be provided that the row of disks is formed by a plurality of packages aligned with one another. If a limited area of the disks of the row of disks is replaced, it is generally sufficient to replace only one or two of these packages and not to replace the remaining packages.

Auch ermöglicht die Erfindung es auf einfache Weise, die zueinander parallelen Zahnscheiben eines Paketes zur Längsrichtung des Trägers spitzwinklig geneigt anzuordnen, d. h. einen spitzwinkligen Richtwinkel vorzusehen. Und zwar kann man bei der Herstellung der Pakete die Scheiben in irgendeinem gewünschten Richtwinkel zur Längsrichtung des Paketes anordnen, so daß das Paket einen parallelogrammförmigen Umriß hat und die Eckenwinkel dieses Parallelogrammes bleiben infolge der Reibungskräfte zwischen den vielen Scheiben eines solchen Paketes auch bei noch vom Träger gesonderten Transport des Paketes erhalten und auch bei der Montage des Paketes auf dem Träger erhalten. Hierzu ist es nur erforderlich, die Scheiben des Paketes mittels der mindestens einen Spannvorrichtung ausreichend stark aneinanderzudrücken.The invention also makes it possible in a simple manner to arrange the toothed disks of a package parallel to one another at an acute angle to the longitudinal direction of the carrier, i. H. to provide an acute-angled straightening angle. In fact, during the manufacture of the packages, the panes can be arranged in any desired directional angle with respect to the longitudinal direction of the package, so that the package has a parallelogram shape and the corner angles of this parallelogram remain due to the frictional forces between the many panes of such a package even when the carrier is removed receive separate transport of the package and also receive when mounting the package on the carrier. For this purpose, it is only necessary to press the panes of the package sufficiently strongly together using the at least one clamping device.

Ein Vorteil ist auch, daß man, wenn die Kardierplatte mehrere Zahnfelder aufweist, die Richtwinkel der Scheiben jedes Zahnfeldes von Zahnfeld zu Zahnfeld unterschiedlich vorsehen kann zwecks Erzielung von Gassenfreiheit der Zahnfeldanordnung dieser Kardierplatte.It is also an advantage that, if the carding plate has a plurality of tooth fields, the straightening angles of the disks of each tooth field can be provided differently from tooth field to tooth field in order to ensure that the tooth field arrangement of this card plate is free of aisles.

Es ergibt sich auch sehr guter Halt des einzelnen Paketes auf dem Träger, da die Rücken der Scheiben an die Auflagefläche des Trägers fest angepreßt werden können.There is also a very good hold of the individual package on the carrier, since the backs of the panes can be pressed firmly against the support surface of the carrier.

Da die Aufspannmittel in Einbuchtungen der Scheiben des Paketes eingreifen, können sie auch den Anlagedruck des Paketes an den Träger vergleichmäßigen. Dies kann zweckmässig dadurch erreicht werden, daß die Aufspannmittel einen den zweiten Kanal des Paketes durchdringenden Profilstab aufweisen, der sich quer zu seiner Längsrichtung erstreckende Gewindebohrungen aufweist, in die sich am Träger abstützende Spannschrauben eingeschraubt sind. Wenn man diese Spannschrauben mit Drehmomentschlüsseln anzieht, ergibt sich auch über die Länge des Paketes sehr gleichmäßiger Anpreßdruck an den Träger. Diese Ausbildung der Aufspannmittel ist auch baulich besonders einfach und ermöglicht denkbar einfache Montage des Paketes am Träger und auch besonders leichtes Auswechseln eines Paketes gegen ein neues Paket.Since the clamping means engage in the indentations of the panes of the package, they can also equalize the contact pressure of the package with the carrier. This can expediently be achieved in that the clamping means have a profile rod penetrating the second channel of the package and having threaded bores extending transversely to its longitudinal direction, into which tensioning screws supporting the carrier are screwed. If you tighten these clamping screws with torque wrenches, there is very even contact pressure over the length of the package to the carrier. This design of the clamping means is also structurally particularly simple and enables the package to be mounted on the carrier in a very simple manner and also makes it particularly easy to replace a package with a new package.

Auch ermöglicht die Erfindung höhere Präzision der Stellung der Scheiben als bei ihrer Befestigung mittels Z-förmigen Haltewinkeln oder Clipsen, die zumindest in vielen Fällen auch Nachjustierung und/oder Nachschleifen des Zahnfeldes nach der Montage auf dem Träger überflüssig macht. U. a. zu diesem Zweck kann bevorzugt vorgesehen sein, daß der zweite Kanal des Paketes schwalbenschwanzförmigen Querschnitt aufweist und die Aufspannmittel mindestens einen Profilstab mit ebenfalls schwalbenschwanzförmigem Querschnitt oder Querschnittsbereich aufweisen, der an den die Hinterschneidungsflächen bildenden Schrägflächen des zweiten Kanales formschlüssig anliegt. Hierdurch kann eine sehr genaue Selbstjustierung des Paketes bei seinem Aufspannen auf dem Träger stattfinden und die Scheiben stehen im Paket sehr präzise.The invention also enables greater precision in the position of the disks than when they are fastened by means of Z-shaped brackets or clips, which at least in many cases also makes it unnecessary to readjust and / or regrind the tooth field after mounting on the carrier. Among others For this purpose it can preferably be provided that the second channel of the package has a dovetail-shaped cross section and the clamping means have at least one profile bar with a dovetail-shaped cross section or cross-sectional area that bears in a form-fitting manner on the inclined surfaces of the second channel forming the undercut surfaces. As a result, a very precise self-adjustment of the package can take place when it is clamped on the carrier and the disks in the package are very precise.

Anstatt die den zweiten Kanal bildenden Einbuchtungen der Scheiben eines Paketes mit Schwalbenschwanzprofil zu versehen, können sie in manchen Fällen auch andere geeignete Profile aufweisen, bspw. T-förmiges Profil, wobei dann in diesen zweiten Kanal bspw. ein Stab rechteckförmigen Profils eingesetzt werden kann, vorzugsweise ohne Seitenspiel oder mit geringem Seitenspiel der in diesen Einbuchtungen auf den durch das T-Profil gebildeten beiden Schultern der Scheiben aufliegt und durch sich am Träger abstützende, in ihn eingeschraubte Spannschrauben od. dergl. in Richtung auf den Träger zum Halten des Paketes auf dem Träger gezogen ist.Instead of providing the indentations of the panes of a package with dovetail profiles forming the second channel, in some cases they can also have other suitable profiles, for example a T-shaped profile, in which case a rod with a rectangular profile can then be inserted, for example. preferably without side play or with little side play which rests in these indentations on the two shoulders of the disks formed by the T-profile and by means of tensioning screws or the like which are supported on the support and screwed into it in the direction of the support for holding the package on the Carrier is pulled.

Im allgemeinen ist es ausreichend, wenn das Paket einen einzigen zweiten Kanal aufweist. Die diesen zweiten Kanal bildenden, miteinander fluchtenden Einbuchtungen der Scheiben können zweckmäßig identisch ausgebildet sein. Auch die einen ersten Kanal bildenden, miteinander fluchtenden Ausnehmungen der Scheiben können unter sich gleich ausgebildet sein.In general, it is sufficient if the packet has a single second channel. The indentations of the disks forming this second channel and aligned with one another can expediently be of identical design. The recesses of the disks which form a first channel and are in alignment with one another can also be of identical design.

Zur einfachen Herstellung der Scheiben ist es zweckmäßig, wenn jede Scheibe konstante Dicke hat. Dabei ist es zweckmäßig, wenn alle Zahnscheiben einer Scheibenreihe unter sich gleiche Dic!<e haben. Da die Zahnscheiben voneinander Abstand haben sollen, können in diesem Fall außer den Zahnscheiben noch Distanzscheiben das Paket mit bilden, wobei zwischen je zwei Zahnscheiben mindestens eine Distanzscheibe zwischengefügt ist.For simple manufacture of the panes, it is expedient if each pane has a constant thickness. It is useful if all toothed lock washers in a row of discs have the same thickness among themselves. Since the toothed disks should be spaced from one another, in this case, apart from the toothed disks, spacer disks can also form the package, with at least one spacer disk being interposed between two toothed disks.

Die Zahnscheiben und die Distanzscheiben können zweckmäßig aus Metall, vorzugsweise aus Stahl bestehen.The toothed disks and the spacer disks can expediently consist of metal, preferably of steel.

Es ist auch möglich, die Zahnscheiben so auszubilden, daß ihre Füße dicker als ihre die Zähne aufweisenden Zahnbereiche sind. Man kann dann solche Zahnscheiben in der Reihe direkt aneinander ansetzen, also auf Distanzscheiben verzichten, falls die Dicke der Füsse die gewünschten Abstände zwischen den Zahnbereichen der benachbarten Zahnscheiben ergeben.It is also possible to design the toothed disks in such a way that their feet are thicker than their toothed areas. Such toothed disks can then be attached directly to one another in the row, that is to say dispensing with spacer disks if the thickness of the feet results in the desired distances between the tooth areas of the adjacent toothed disks.

Obwohl es im allgemeinen vorteilhaft und ausreichend ist, einen einzigen zweiten Kanal für das Paket vorzusehen, können gegebenenfalls auch zwei oder mehr solche zweiten Kanäle vorgesehen sein, bspw. um das Paket noch gleichmäßiger aufzuspannen oder die Präzision seiner Anordnung noch zu erhöhen.Although it is generally advantageous and sufficient to provide a single second channel for the package, two or more such second channels may optionally be provided hen, for example, to stretch the package evenly or to increase the precision of its arrangement.

Die Zähne der Zahnscheiben können in irgendeiner geeigneten Art vorgesehen sein. Falls erwünscht, ist es auch möglich, daß die Zahnspitzen einer Zahnscheibe entlang einem geometrischen Kreisbogen angeordnet sind, dessen Radius ungefähr dem Radius des Tambours entspricht.The teeth of the toothed disks can be provided in any suitable manner. If desired, it is also possible for the tooth tips of a toothed disk to be arranged along a geometric circular arc, the radius of which approximately corresponds to the radius of the drum.

Zweckmäßig kann vorgesehen sein, daß das Paket insgesamt zwei erste Kanäle aufweist, die zweckmäßig zu der Längsmittelebene des Paketes symmetrisch zueinander angeordnet sein können, vorzugsweise in der Nähe der beiden Längsseiten des Paketes. Es ist jedoch auch denkbar, daß man in manchen Fällen mit einem einzigen ersten Kanal auskommen kann, insbesondere dann, wenn dieser sich ungefähr in der Längsmittelebene des Paketes befindet. In manchen Fällen können auch mehr als zwei erste Kanäle vorgesehen sein, wenn besonders hohe Eigensteifigkeit des Paketes durch die die ersten Kanäle durchdringenden Spannvorrichtungen erreicht werden soll.Advantageously, it can be provided that the package has a total of two first channels, which can be arranged to be symmetrical to the longitudinal center plane of the package, preferably in the vicinity of the two long sides of the package. However, it is also conceivable that in some cases a single first channel can be used, in particular if this is approximately in the longitudinal median plane of the package. In some cases, more than two first channels can also be provided if particularly high rigidity of the package is to be achieved by the tensioning devices penetrating the first channels.

Die den ersten Kanal bildenden Ausnehmungen der Scheiben können vorzugsweise Löcher sein.The recesses of the disks forming the first channel can preferably be holes.

Wenn das Kardierelement mehrere Zahnfelder aufweist, die vorzugsweise ungefähr gleich breit sein können, können zweckmäßig eine oder mehrere der in Anspruch 10 beschriebenen Maßnahmen vorgesehen sein, wodurch die Kardierarbeit weiter verbessert wird.If the carding element has a plurality of tooth fields, which can preferably be approximately of the same width, one or more of the measures described in claim 10 can expediently be provided, as a result of which the carding work is further improved.

Die in Fig. 1 bis 4 dargestellte langgestreckte Kardierplatte 10 weist einen massiven, balkenförmigen Träger 11 ungefähr konstanten Querschnittsprofiles aus Aluminium oder einem sonstigen Metall auf, dessen Längsrichtung sich, wenn er an einer Karde angeordnet ist, parallel zur Drehachse des Tambours dieser Karde erstreckt und an der Karde unbeweglich angeordnet wird. Dieser Träger 11 ist sehr stabil, damit er sich im Betrieb nicht durchbiegt. Er trägt in diesem Ausführungsbeispiel insgesamt vier zueinander parallele, ungefähr gleich breite Scheibenreihen 12a-12d, die je ein Zahnfeld 13 bilden und in Rotationsrichtung (Pfeil A) des in Fig. 2 bei 23 strichpunktiert angedeuteten Tambours der Karde dicht hintereinander angeordnet sind. Jedes solches Zahnfeld 13 ist durch die Zähne 17 der durch Distanzscheiben 16 distanzierten Zahnscheiben 15 einer einzigen Reihe 12a-12d dieser zueinander parallelen, ebenen, mit ihren Breitseiten aneinander anliegenden Scheiben 15, 16 gebildet.The elongated carding plate 10 shown in Fig. 1 to 4 has a solid, beam-shaped carrier 11 of approximately constant cross-sectional profile made of aluminum or other metal, the longitudinal direction of which, if it is arranged on a card, extends parallel to the axis of rotation of the spool of this card and is arranged immovably on the card. This carrier 11 is very stable so that it does not bend during operation. In this exemplary embodiment, it carries a total of four parallel, approximately equally wide rows of disks 12a-12d, which each form a tooth field 13 and are arranged closely one behind the other in the direction of rotation (arrow A) of the carding drum indicated by dash-dotted lines at 23 in FIG. 2. Each such tooth field 13 is formed by the teeth 17 of the toothed disks 15, spaced apart by spacer disks 16, of a single row 12a-12d of these parallel, flat disks 15, 16 which abut one another with their broad sides.

Die Scheiben 15, 16 jeder solchen Scheibenreihe 12a-12d sind zu einem einzigen Paket 21 oder mehreren miteinander fluchtenden Paketen zusammengefaßt, wobei die Scheiben 15, 16 jedes Paketes 21 durch je zwei Spannvorrichtungen 19 zusammengehalten sind.The disks 15, 16 of each such row of disks 12a-12d are combined to form a single package 21 or more packages aligned with one another, the disks 15, 16 of each package 21 being held together by two clamping devices 19 each.

Das einzelne Paket 21 besteht aus einer Vielzahl von gleichlangen, dünnen, gerade Rückkanten 14 aufweisenden, gestanzten Scheiben 15, 16. Es sind dabei zwei Arten von Scheiben 15, 16 vorgesehen. Die eine Art sind die Zahnscheiben 15, bspw. gemäß Fig. 5, und die andere Art sind zahnlose Distanzscheiben 16, bspw. gemäß Fig. 6. Die Zahnscheiben 15 des einzelnen Zahnfeldes 13 sind unter sich gleich, desgleichen die Distanzscheiben 16. Jedoch können die Zahnscheiben 15 unterschiedlicher Zahnfelder 13 unterschiedlich gestaltet sein, insbesondere bezüglich der Zahnformen der Zahnhöhen, der Zahnteilungen und der Anzahl ihrer Zähne 17. Die Distanzscheiben 16 eines Zahnfeldes 13 können ebenfalls unter sich gleich ausgebildet sein und können für alle Zahnfelder 13 gleich sein oder unterschiedlich sein, bspw. für mindestens zwei Zahnfelder 13 unterschiedliche Dicken aufweisen, um die Zähnedichten dieser Zahnfelder 13 hierdurch unterschiedlich vorzusehen. Unter Zähnedichte des Zahnfeldes ist die Anzahl der Zähne/ Flächeneinheit verstanden. Bevorzugt können die Zähne 17 der Zahnfelder 13 in Tambourrotationsrichtung (Pfeil A) von Zahnfeld 13 zu Zahnfeld 13 feiner, die Zähnedichten größer und die Zahnhöhen kleiner werden.The individual package 21 consists of a multiplicity of punched disks 15, 16 of equal length, thin, straight rear edges 14, and two types of disks 15, 16 are provided. One type is the toothed disks 15, for example according to FIG. 5, and the other type is toothless spacer disks 16, for example according to FIG. 6. The toothed disks 15 of the individual tooth field 13 are the same among themselves, as are the spacer disks 16. However, the toothed disks 15 of different tooth fields 13 can be designed differently, in particular with regard to the tooth shapes of the tooth heights, the tooth pitches and the number of their teeth 17. The spacer disks 16 of a tooth field 13 can also be of identical design and can be the same or different for all tooth fields 13 , for example, have different thicknesses for at least two tooth fields 13 in order to provide the tooth densities of these tooth fields 13 differently. The tooth density of the tooth field means the number of teeth / unit area. The teeth 17 of the tooth fields 13 can preferably be finer in the drum rotation direction (arrow A) from tooth field 13 to tooth field 13, the tooth densities larger and the tooth heights smaller.

Die Länge jedes Zahnfeldes 13 entspricht ungefähr der Arbeitsbreite des Tambours der betreffenden Karde.The length of each tooth field 13 corresponds approximately to the working width of the reel of the card in question.

Die Zahnscheiben 15 und die Distanzscheiben 16 können zweckmäßig aus Stahl bestehen.The toothed disks 15 and the spacers 16 can suitably consist of steel.

Die ein Zahnfeld 13 bildenden Zahnscheiben 15 und Distanzscheiben 16 sind zueinander parallel und stehen auf der eine Auflagefläche 20 für ihre geraden Rückkanten 14 bildenden ebenen Fläche des Trägers 11 senkrecht, können jedoch zur Längsrichtung des Zahnfeldes 13 unter einem Richtwinkel a angeordnet sein, wie es in Fig. 7 an einem Ausführungsbeispiel einer ausschnittsweise dargestellten Scheibenreihe gezeigt ist, so daß in diesem Fall der Umriß der Scheibenreihe 12 parallelogrammförmig ist. Im Ausführungsbeispiel nach Fig. 1 ist noch dargestellt, daß die Richtwinkel a von Zahnfeld zu Zahnfeld gegensinnig zur Tambourrotationsrichtung A geneigt angeordnet sein können, so daß in diesem Ausführungsbeispiel die Zahnfelder eine zickzack-förmige Anordnung ergeben. Die Richtwinkel a können also von Zahnfeld 13 zu Zahnfeld 13 unterschiedlich vorgesehen sein, gegebenenfalls auch 90° betragen, in welchem letzteren Fall dann der Umriß des betreffenden Zahnfeldes 13 rechteckförmig ist. Durch die Anordnung mehrerer Zahnfelder 13 dicht hintereinander, indem dabei unterschiedliche Richtwinkel a von Zahnfeld 13 zu Zahnfeld 13 vorgesehen sein können, ergibt sich ein Gesamtzahnfeld, das keine Gassen hat, d. h. keine sich über die Gesamtanordnung der Zahnfelder 13 in ungefährer Faserlaufrichtung erstreckende gerade Lücken aufweist, durch die Fasern unabgelenkt hindurchlaufen können.The toothed disks 15 and spacer disks 16 forming a tooth field 13 are parallel to one another and are perpendicular to the flat surface of the carrier 11 forming a support surface 20 for their straight rear edges 14, but can be arranged at a directional angle a to the longitudinal direction of the tooth field 13, as shown in FIG Fig. 7 is shown on an embodiment of a section of disks shown in sections, so that in this case the outline of the row of disks 12 is parallelogram. In the embodiment of FIG. 1 it is also shown that the Straightening angle a can be arranged from tooth field to tooth field in the opposite direction to the drum rotation direction A, so that in this exemplary embodiment the tooth fields result in a zigzag-shaped arrangement. The straightening angles α can therefore be provided differently from tooth field 13 to tooth field 13, possibly also 90 °, in which case the outline of the tooth field 13 in question is rectangular. The arrangement of a plurality of tooth fields 13 one behind the other, in that different straightening angles a from tooth field 13 to tooth field 13 can be provided, results in an overall tooth field which has no lanes, ie does not have any straight gaps extending over the overall arrangement of tooth fields 13 in the approximate fiber running direction through which fibers can pass undeflected.

Dies verbessert die Kardierarbeit dieser Kardierplatte 10 weiter.This further improves the carding work of this carding plate 10.

Die vier ebenen Auflageflächen 20 für die vier Scheibenreihen 12a-12d sind, wie aus Fig. 2 ersichtlich, zueinander schwach geneigt angeordnet, derart, daß hierdurch eine Anpassung der Zahnfelder an den bei 23 strichpunktiert angedeuteten Ausschnitt des Umfanges des Tambours der im übrigen nicht näher dargestellten Karde erfolgt, bei der es sich beispielsweise um eine Wanderdeckelkarde, eine Krempel oder eine sonstige Karde handeln kann. Zur weiteren Anpassung dieser Zahnfelder an die Krümmung des Tambourbeschlages kann ferner noch vorgesehen sein, daß die Zahnspitzen der Zähne 17 der einzelnen Zahnscheibe 15 nicht wie in Fig. 5 dargestellt auf einer Geraden liegen, sondern auf einer geometrischen, konkaven kreisbogenförmigen Kurve 23', deren Radius dem des Tambours 23 ungefähr entspricht.The four flat bearing surfaces 20 for the four rows of disks 12a-12d are, as shown in FIG. 2, arranged slightly inclined to one another, such that in this way an adaptation of the tooth fields to the section of the circumference of the drum indicated by dash-dotted lines at 23 is not closer to the rest shown card is carried out, which can be, for example, a revolving card, card or other card. To further adapt these tooth fields to the curvature of the drum fitting, it can further be provided that the tooth tips of the teeth 17 of the individual toothed disk 15 do not lie on a straight line, as shown in FIG. 5, but on a geometric, concave circular arc-shaped curve 23 ', the Radius roughly corresponds to that of the reel 23.

Die Zahnfelder 13 des Trägers 11 können beispielsweise 5 eine Länge von 1 m bis 1,50 m haben, jedoch je nach Karde auch kürzer oder länger sein.The tooth fields 13 of the carrier 11 can for example 5 have a length of 1 m to 1.50 m, but can also be shorter or longer depending on the card.

In dem Ausführungsbeispiel nach Fig. 3 ist die dargestellte Scheibenreihe 12a durch ein einziges, gebrochen dargestelltes Paket 21 aus Zahnscheiben 15 und Distanzscheiben 16 gebildet, welche mit ihren Breitseiten aneinander anliegen und durch zwei die Löcher 24 der Scheiben 14,15 durchdringende Spannvorrichtungen 19, von denen nur eine zu sehen ist, fest aneinander angedrückt sind, so daß dieses Paket 21, wenn es vom Träger 11 abgehoben ist, durch diese Spannvorrichtungen 19 zusammengehalten ist und diesen Zusammenhalt auch auf dem Träger 11 behält und hierdurch auch der Gesamtzusammenhalt dieses Paketes 21 auf dem Träger 11 verbessert wird.In the exemplary embodiment according to FIG. 3, the row of disks 12a shown is formed by a single, broken package 21 consisting of toothed disks 15 and spacer disks 16, which bear against one another with their broad sides and by two tensioning devices 19, which penetrate the holes 24 of the disks 14, 15 which only one can be seen are firmly pressed together so that this package 21, when it is lifted from the carrier 11, is held together by these tensioning devices 19 and also maintains this cohesion on the carrier 11 and thereby also the overall cohesion of this package 21 the carrier 11 is improved.

Dieses Paket 21 kann je nach Dicke der Scheiben 15, 16 aus mehreren hundert bis mehreren tausend Scheiben 15, 16 bestehen, von denen in Fig. 3 nur einige dargestellt sind. Zwischen je zwei Zahnscheiben 15 ist eine Distanzscheibe 16 angeordnet. Diese Scheiben 15. 16 sind von je zwei kreisrunden Löchern 24 (Fig. 5, 6) durchdrungen. die in der Nähe der beiden Längsenden der betreffenden Scheibe angeordnet sind. Diese Löcher 24 biiden im Paket 21 zwei fluchtende Lochreihen, die zwei das Paket 21 durchdringende, gerade, erste Kanäle 24' (Fig. 3, 7) bilden und jeder Kanal 24' ist von einer eine Zugvorrichtung bildenden Spannvorrichtung 19 durchdrungen, die über ihn nicht nach außen vorsteht. Hierdurch können gegebenenfalls mehrere gleiche Scheiben 15, 16 aufweisende Pakete abstandslos miteinander fluchtend zu einer Scheibenreihe am Träger 11 angeordnet werden, was das Auswechseln abgenutzter Zahnscheiben erleichtert, wenn nur im einen oder in einigen der ingesamt vorhandenen Pakete angeordnete Zahnscheiben ausgewechselt werden müssen.Depending on the thickness of the disks 15, 16, this package 21 can consist of several hundred to several thousand disks 15, 16, only a few of which are shown in FIG. 3. A spacer 16 is arranged between each two toothed disks 15. These disks 15, 16 are penetrated by two circular holes 24 (FIGS. 5, 6). which are arranged in the vicinity of the two longitudinal ends of the disc in question. These holes 24 form in the package 21 two aligned rows of holes which form two straight first channels 24 '(FIGS. 3, 7) penetrating the package 21 and each channel 24' is penetrated by a tensioning device 19 which forms a pulling device and passes over it does not protrude outwards. As a result, a plurality of packages having the same disks 15, 16 can optionally be arranged flush with one another to form a row of disks on the carrier 11, which makes it easier to replace worn toothed disks if toothed disks arranged only in one or in some of the packages as a whole need to be replaced.

Die Spannvorrichtung 19 besteht in diesem Ausführungsbeispiel aus einem geraden metallischen Zugstab 26 und einer Spannschraube 27. Der Zugstab 26 weist an seinem einen Ende einen kegelstumpfförmigen Kopf 26' auf, der in die hier entsprechend erweiterten Löcher 24 der letzten drei Scheiben 15, 16 wie aus Fig. 3 ersichtlich, hierduch hier ein Widerlager findend, versenkt formschlüssig eingreift und die Spannschraube 27 weist ebenfalls einen kegelstumpfförmigen Kopf 27' auf, der in die betreffenden entsprechend erweiterten Löcher 24 der letzten beiden Scheiben 15, 16, hier ebenfalls ein Widerlager findend, versenkt formschlüssig eingreift und in eine Sackgewindebohrung des Zugstabes 26 die Gesamtheit der Scheiben 15, 16 dieser ein Zahnfeld 13 bildenden Scheibenreihe 12a zu dem Paket 21 miteinander verspannend eingeschraubt ist.In this exemplary embodiment, the tensioning device 19 consists of a straight metallic tension rod 26 and a tension screw 27. The tension rod 26 has at one end a frustoconical head 26 ', which extends into the correspondingly enlarged holes 24 of the last three disks 15, 16 Fig. 3 can be seen, here finding an abutment, countersunk engages positively and the clamping screw 27 also has a frustoconical head 27 ', which sinks into the relevant correspondingly enlarged holes 24 of the last two disks 15, 16, also here finding an abutment engages in a form-fitting manner and the entirety of the disks 15, 16 of this row of disks 12a forming a tooth field 13 is screwed together to form the packet 21 in a blind threaded bore of the tension rod 26.

Der gerade Zugstab 26 hat einen im Querschnitt kreisrunden Schaft 26", der mit Gleitlagerspiel in den von ihm durchdrungenen Löchern 24 der Scheiben 15, 16 liegt.The straight pull rod 26 has a shaft 26 ″ which is circular in cross section and which, with plain bearing play, lies in the holes 24 in the disks 15, 16 which it penetrates.

Jede der Scheibenreihen 12a-12d bildet für sich ein solches Paket 21, wobei jedes Paket 21 durch zwei solche Spannvorrichtungen 19, die die beiden ersten Kanäle 24' durchdringen, zusammengehalten ist, und alle Scheiben 15, 16 dieses Paketes 21 sind hierdurch mit ihren Breitseiten aneinander angepreßt. Jedes solches Paket 21 bildet so eine Baueinheit, die auf die ihm zugeordnete ebene Fläche 20 des Trägers 11 mit den geraden Rückkanten 14 ihrer Scheiben 15, 16 aufgesetzt wird. Um das einzelne Paket 21 auf dem Träger 11 zu befestigen und es hierdurch auch gleichmäßig und fest an die zugeordnete Auflagefläche 20 des Trägers 11 anzupressen und es dabei auch selbsttätig zu justieren, wobei auch die enge Hintereinanderanordnung der Scheibenreihen 12a-12d über die volle Breite des Trägers 11 erreicht werden soll, ist folgendes vorgesehen :Each of the rows of disks 12a-12d forms such a package 21, each package 21 being held together by two such tensioning devices 19 which penetrate the first two channels 24 ', and all disks 15, 16 of this package 21 are thereby with their broad sides pressed together. Each such package 21 thus forms a structural unit which is placed on its associated flat surface 20 of the carrier 11 with the straight rear edges 14 of its disks 15, 16. In order to fasten the individual package 21 on the carrier 11 and thereby also press it evenly and firmly against the associated support surface 20 of the carrier 11 and also to adjust it automatically, the close succession of the rows of disks 12a-12d over the full width of the Carrier 11 is to be reached, the following is provided:

In jeder Scheibe 15, 16 jedes Paketes 21 ist untenseitig mittig eine schwalbenschwanzförmige, zum Träger 11 hin offene Einbuchtung 30 vorgesehen, die alle gleich ausgebildet sind und im Paket 21 miteinander fluchten. Diese Einbuchtungen 30 bilden so in dem Paket 21 einen durchgehenden geraden Kanal 30' (zweiter Kanal), der sich entlang der Längsmitte des Paketes 21 über die volle Länge des Paketes 21 erstreckt und schwalbenschwanzförmigen Querschnitt aufweist, so daß schräge, ebene Hinterschneidungen bildende Hinterschneidungsflächen 31 entstehen. Alle zweiten Kanäle 30' der Pakete 21 haben gleiche Querschnittsgröße und Gestalt. Die Pakete 21 haben untereinander auch ungefähr gleiche Breite, die der Breite ihrer Zahnfelder entspricht und bspw. zweckmäßig 3-12 cm betragen kann.In each disc 15, 16 of each package 21, a dovetail-shaped indentation 30, which is open towards the carrier 11, is provided in the center on the underside, all of which have the same design and are aligned with one another in the package 21. These indentations 30 thus form a continuous straight channel 30 ′ (second channel) in the package 21, which extends along the longitudinal center of the package 21 over the full length of the package 21 and has a dovetail-shaped cross section, so that oblique undercut surfaces 31 are formed which form flat undercuts. All second channels 30 'of the packets 21 have the same cross-sectional size and shape. The packets 21 also have approximately the same width with one another, which corresponds to the width of their tooth fields and, for example, can expediently be 3-12 cm.

In den zweiten Kanal 30' jedes Paketes 21 ist je ein massiver Profilstab 32 eingesetzt, wie es Fig. 4 zeigt, dessen Profil aus einem schwalbenschwanzförmigen Bereich und einem rechteckförmigen Bereich besteht. Der im Querschnitt schwalbenschwanzförmige Kopf 34 des Profilstabes 32 hat schräge, ebene Seitenflanken 33, die miteinander denselben Winkel wie die schrägen, ebenen Hinterschneidungen 31 des zweiten Kanales 30' des Paketes 21 einschließen, wobei die Breite der ebenen Stirnfläche des Kopfes 34 des Profilstabes 32 etwas kleiner als die Breite des ebenen Bodens des zweiten Kanales 30' ist. Hierdurch kann der Profilstab 32 problemlos in den zweiten Kanal 30' eingesetzt werden. Er erstreckt sich zumindest über die Länge des zweiten Kanales 30', so daß er sämtliche Scheiben 15, 16 des betreffenden Paketes 21 an den Hinterschneidungsflächen 31 des zweiten Kanales 30' formschlüssig kontaktiert.In the second channel 30 'of each package 21, a solid profile rod 32 is inserted, as shown in FIG. 4, the profile of which consists of a dovetail area and a rectangular area. The cross-section dovetail-shaped head 34 of the profile bar 32 has oblique, flat side flanks 33, which together enclose the same angle as the oblique, plane undercuts 31 of the second channel 30 'of the package 21, the width of the flat end face of the head 34 of the profile bar 32 being somewhat is smaller than the width of the flat bottom of the second channel 30 '. As a result, the profile rod 32 can be inserted into the second channel 30 'without any problems. It extends at least over the length of the second channel 30 ', so that it positively contacts all the disks 15, 16 of the package 21 in question on the undercut surfaces 31 of the second channel 30'.

Der Profilstab 32 ragt durch die dem Träger 11 zugewendete Öffnung 41 des zweiten Kanales 30' hindurch mit seinem im Querschnitt rechteckförmigen Fußteil 35 in eine dessen Längsseiten führende Längsnut 36 in der betreffenden Auflagefläche 20 des Trägers 11 mit geringem Gleitlagerseitenspiel hinein. In dieses Fußteil 35 sind in gleichmäßigen Abständen Gewindelöcher 37 eingelassen, in die Spannschrauben 39 eingeschraubt sind, die in Löchern 40 des Trägers 11 versenkt angeordnet sind und deren Köpfe sich auf Absätzen dieser Löcher 40 über Unterlagscheiben abstützen. Durch Drehen dieser Schrauben 39 wird der Profilstab 32 in Richtung auf den Träger 11 zu in die zugeordnete Längsnut 36 tiefer eindringend bewegt und hierdurch zieht er alle Scheiben 15, 16 dieses Paketes 21 an die betreffende Auflagefläche 20 fest an, so daß sämtliche Scheiben 15, 16 dieses Paketes 21 satt und fest mit erheblicher Kraft an die Auflagefläche 20 dieses Trägers 11 angedrückt sind. Diese Schrauben 39 und der Profilstab 32 bilden so zusammen Aufspannmittel, die durch das Zusammenwirken der Schwalbenschwanzprofile des Kanales 30' und des Profilstabes 32 das Paket 21 und seine Scheiben 15, 16 bei dessen Aufspannen auf die Auflagefläche 20 des Trägers 11 gleichzeitig exakt ausrichten und justieren. Es kann hierdurch zumindest in vielen Fällen eine Nachjustierung des Paketes 21 auf dem Träger entfallen, desgleichen ein Nachschleifen der Zähne 17.The profile rod 32 protrudes through the opening 41 facing the carrier 11 of the second channel 30 'with its base part 35, which is rectangular in cross section, into a longitudinal groove 36, which leads on the longitudinal sides thereof, in the relevant contact surface 20 of the carrier 11 with little sliding bearing side play. In this foot part 35, threaded holes 37 are let in at regular intervals, into which clamping screws 39 are screwed, which are sunk in holes 40 of the carrier 11 and whose heads are supported on heels of these holes 40 via washers. By turning these screws 39, the profile rod 32 is moved in the direction of the carrier 11 to penetrate deeper into the associated longitudinal groove 36, and as a result he firmly pulls all the disks 15, 16 of this packet 21 onto the relevant bearing surface 20, so that all the disks 15, 16 of this package 21 are firmly and firmly pressed with considerable force on the bearing surface 20 of this support 11. These screws 39 and the profile rod 32 thus together form clamping means which, by the interaction of the dovetail profiles of the channel 30 'and the profile rod 32, precisely align and adjust the package 21 and its washers 15, 16 when it is clamped onto the support surface 20 of the carrier 11 . As a result, at least in many cases there is no need to readjust the package 21 on the carrier, and likewise to regrind the teeth 17.

Wie in Fig. 1 dargestellt, schließen die Zahnfelder 13 der vier Scheibenreihen 12a-12b gemäß Fig. 1 und 2 bevorzugt abstandslos aneinander an, so daß ein ununterbrochenes Gesamtzahnfeld entsteht, das durch die vier Pakete 21 gebildet ist. Die Breite des Trägers 11 ist für die Zahnfelder 13 optimal ausgenutzt, da sie die volle Breite des Trägers überdecken. Diese Kardierplatte hat zahlreiche Vorteile, z. B. besonders gute Kardierarbeit, geringe Staubentwicklung, es besteht keine Verstopfungsgefahr des durch die Scheibenreihen 12a-12d gebildeten Beschlages dieser Kardierplatte, einfache, rasche und genaue Montage der Pakete 21, leichtes Auswechseln der Pakete 21 usw.As shown in FIG. 1, the tooth fields 13 of the four rows of disks 12a-12b according to FIGS. 1 and 2 preferably adjoin one another without a gap, so that an uninterrupted overall tooth field is formed which is formed by the four packets 21. The width of the carrier 11 is optimally used for the tooth fields 13, since they cover the full width of the carrier. This carding plate has numerous advantages, e.g. B. particularly good carding work, low dust development, there is no risk of clogging of the fitting of this carding plate formed by the rows of disks 12a-12d, simple, quick and accurate assembly of the packets 21, easy replacement of the packets 21, etc.

Auf dem Träger 11 können auch weniger oder mehr als vier Scheibenreihen angeordnet sein.Fewer or more than four rows of disks can also be arranged on the carrier 11.

Im untersten Grenzfall kann auf dem Träger 11 eine einzige Scheibenreihe angeordnet sein. Eine solche Kardierplatte mit einem einzigen Zahnfeld kann ebenfalls unbeweglich angeordnet werden oder aber auch einen Deckel eines Wanderdeckels einer Wanderdeckelkarde bilden. Dabei kann die Arbeitsbreite des dann einzigen Zahnfeldes ebenfalls gleich der Breite des Träger sein, wodurch bei gegebener Breite des Trägers die Kardierarbeit verbessert wird.In the lowest limit case, a single row of disks can be arranged on the carrier 11. Such a carding plate with a single tooth field can also be arranged immovably or can also form a cover of a revolving cover of a revolving flat card. The working width of the then single tooth field can also be equal to the width of the carrier, whereby the carding work is improved for a given width of the carrier.

Die in Tambourrotationsrichtung gemessene Breite des Trägers 11 und damit die Breite der Zahnfelderanordnung kann, wenn sie mehrere Zahnfelder aufweist, je nach Anwendungsfall und Anzahl der Zahnfelder 6 bis 25 cm betragen, in manchen Fällen auch größer oder kleiner sein. Wenn die Kardierplatte als Deckel eines Wanderdeckels ein einziges Zahnfeld aufweist, kann diese Breite im allgemeinen zweckmäßig ca. 3-4 cm betragen und, wenn die Kardierplatte dagegen an der Karde unbeweglich - ein einziges Zahnfeld aufweisend-angeordnet wird, kann ihre Breite im allgemeinen zweckmäßig ca. 6-12 cm betragen. Auch diese Maße können über- oder unterschritten werden.The width of the carrier 11, measured in the direction of drum rotation, and thus the width of the tooth field arrangement, if it has several tooth fields, can be 6 to 25 cm, depending on the application and number of tooth fields, in some cases also larger or smaller. If the carding plate as the cover of a revolving cover has a single tooth field, this width can in general advantageously be approximately 3-4 cm and, if the carding plate, on the other hand, is immovably arranged on the card - having a single tooth field, its width can in general be expedient approx. 6-12 cm. These dimensions can also be exceeded or undershot.
