Description

Die Erfindung betrifft einen Breithalter für Schlauchware mit einem Rahmen, an dem beidseits rechts und links jeweils wenigstens eine Rollenanordnung befestigt ist, die jeweils eine äußere Führungsrolle aufweist, um die die Schlauchware gelegt ist und die die Schlauchware breithalten, wobei über die Schlauchware an der Führungsrolle eine auf Drehung angetriebene Treibrolle anliegt, die über einen Reibungsschluß die Führungsrolle antreibt und dadurch die Schlauchware transportiert, und mit wenigstens einer Stützrolle, die den von der Schlauchware auf die Führungsrolle ausgeübten Zug aufnimmt.The invention relates to a spreader for tubular goods with a frame to which at least one roller arrangement is fastened on both sides on the right and left, each having an outer guide roller around which the tubular fabric is placed and which hold the tubular fabric wide, with the tubular fabric on the guide roller a drive roller driven for rotation abuts, which drives the guide roller via a frictional connection and thereby transports the tubular goods, and with at least one support roller which receives the tension exerted by the tubular goods on the guide roller.

Einen derartigen Breithalter beschreibt die EP-A-0 267 880. Dort liegt die Treibrolle - über die Schlauchware - an der Außenseite der Führungsrolle an. Damit geht aber der Nachteil einher, daß der über die Schlauchware auf die Führungsrolle ausgeübte Zug dazu führt, daß im Betrieb häufig kein ausreichender Reibungsschluß mehr zwischen den beiden Rollen herrscht, so daß die Führungsrolle und damit die Warenbahn nicht mehr einwandfrei kontinuierlich angetrieben werden. Offenbar um diese Schwierigkeit zu vermeiden liegen dort geneigte Stützrollen an der Innenseite eines wulstförmigen Profils der Führungsrolle an, jedoch vergrößern diese Stützrollen nur noch die Problematik: sie werden ebenfalls über Reibungsschluß angetrieben, wobei deren Lager belastet werden, was wiederum eine entsprechende Verzögerungskraft auf die transportierte Schlauchware ausübt, die dann beim Transport zusätzlich sich wellt bzw. auswölbt.Such a spreader is described in EP-A-0 267 880. There, the drive roller lies on the outside of the guide roller — via the tubular goods. However, this has the disadvantage that the pull exerted on the tubular material on the guide roller leads to the fact that in operation there is often no longer sufficient frictional engagement between the two rollers, so that the guide roller and thus the web are no longer properly driven. Apparently to avoid this difficulty there are inclined support rollers on the inside of a bead-shaped profile of the guide roller, but these support rollers only increase the problem: They are also driven by friction, whereby their bearings are loaded, which in turn has a corresponding deceleration force on the transported Exerts tubing, which then additionally curls or bulges during transport.

Die DE-OS 28 23 978 beschreibt einen Breithalter für Schlauchware, bei der an der Innenseite des Breithalters jeweils ein Paar der Führungsrollen vorgesehen ist, die über eine gemeinsame Treibrolle angetrieben werden, die, ähnlich wie bei der vorstehend diskutierten europäischen Offenlegungsschrift, wie Schlauchware an der Außenseite der Führungsrollen anliegt. Auch hier besteht daher das Problem, daß der im Betrieb von der Schlauchware auf die Führungsrollen ausgeübte Zug den Reibungs- und Kraftschluß zwischen den Rollen unterbricht.DE-OS 28 23 978 describes a spreader for tubular goods, in which a pair of guide rollers is provided on the inside of the spreader, which are driven by a common drive roller, which, similar to the European patent application discussed above, relates to tubular goods the outside of the guide rollers. Here too there is the problem that the tension exerted by the tubular goods on the guide rollers during operation interrupts the frictional and non-positive connection between the rollers.

Zum Stand der Technik sei auch noch hingewiesen auf die EP-A-0 204 660, die einen Breithalter mit endlosen Transportriemen beschreibt, die mit Vorschubrollen lösbar in einem Antriebseingriff stehen. Hier sind Maßnahmen vorgesehen, um die Breite des Breithalters bei durchlaufender Schlauchware von außen ungehindert verändern zu können.With regard to the prior art, reference should also be made to EP-A-0 204 660, which describes a spreader with endless transport belts which are releasably in drive engagement with feed rollers. Measures are provided here in order to be able to change the width of the spreader from the outside unhindered when the tubular material is passing through.

Der Erfindung liegt, ausgehend von einem Breithalter mit den eingangs genannten Merkmalen, die Aufgabe zugrunde, diesen so auszugestalten, daß der Breithalter die Schlauchware einwandfrei transportiert, wobei er auch problemlos auf gegebenenfalls unterschiedliche Schlauchwarenbreiten einstellbar sein soll.The invention is based on a spreader with the features mentioned, the task of designing it so that the spreader transports the tubular goods properly, it should also be easily adjustable to different tubular goods widths if necessary.

Zur Lösung dieser Aufgabe ist die Erfindung dadurch gekennzeichnet, daß die Treibrolle, bezogen auf den Rahmen, an der Innenseite der Führungsrolle anliegt und von der Stützrolle gestützt ist, die an der der Führungsrolle abgewandten Seite am Umfang der Treibrolle anliegt.To achieve this object, the invention is characterized in that the drive roller, based on the frame, on the inside of the Guide roller rests and is supported by the support roller, which rests on the side facing away from the guide roller on the circumference of the drive roller.

Der von der Schlauchware auf die Führungsrolle ausgeübte Zug verstärkt somit allenfalls den Reibungsschluß und Kraftschluß zwischen der Treibrolle und der Führungsrolle, so daß die Schlauchware durch den Breithalter kontinuierlich und ohne Stockungen transportiert wird, und zwar über ihre gesamte, jeweils im Breithalter befindliche Fläche. Die Führungsrolle und die Stützrolle liegen in ein und derselben Ebene, so daß ein Verzug durch winkelig angreifende Stützrollen, wie beim gattungsbildenden Stand der Technik, ebenfalls nicht mehr möglich ist.The tension exerted by the tubular goods on the guide roller thus at most increases the frictional and non-positive connection between the driving roller and the guide roller, so that the tubular goods are transported continuously and without stagnation through the spreader, namely over their entire surface located in the spreader. The guide roller and the support roller lie in one and the same plane, so that warping by angularly acting support rollers, as in the generic state of the art, is also no longer possible.

Bei der einfachsten Anordnung mit einer einzigen Führungsrolle und einer einzigen Stützrolle wird man diese so anordnen, daß die Stützrolle rechtwinklig zur Transportrichtung der Schlauchware sich hinter der Führungsrolle befindet. Bevorzugt wird allerdings eine Anordnung, bei der voneinander beabstandet zwei der Führungsrollen vorgesehen sind, hinter denen in einer symmetrischen Anordnung die Stützrolle angeordnet ist. Hier ordnet man eine einzige Stützrolle den beiden Führungsrollen zu und die beiden Führungsrollen bewirken einen besonders glatten und faltenfreien Transport der Warenbahn durch den Breithalter. An dieser Stelle sei bemerkt, daß der erfindungsgemäße Breithalter vorzugsweise bei einer Maschine Anwendung findet, mit der die Schlauchware merzerisiert wird, und zwar am Eingang einer solchen Maschine.In the simplest arrangement with a single guide roller and a single support roller, these will be arranged so that the support roller is at right angles to the direction of transport of the tubular goods behind the guide roller. However, an arrangement is preferred in which two of the guide rollers are provided at a distance from one another, behind which the support roller is arranged in a symmetrical arrangement. Here you assign a single support roller to the two guide rollers and the two guide rollers ensure a particularly smooth and wrinkle-free transport of the web through the spreader. At this point it should be noted that the spreader according to the invention is preferably used in a machine with which the tubular goods are mercerized, specifically at the entrance to such a machine.

Aus demselben Grunde wird es bevorzugt, wenn in Transportrichtung der Schlauchware hintereinander wenigstens zwei der Rollenanordnungen an beiden Seiten des Rahmens vorgesehen sind. Diese an sich bekannte Maßnahme bewirkt einen besonders glatten, ungehinderten und kontinuierlichen Transport der Schlauchware durch den Breithalter.For the same reason, it is preferred if at least two of the roller arrangements are provided one behind the other on both sides of the frame in the transport direction of the tubular goods. This measure, which is known per se, brings about a particularly smooth, unimpeded and continuous transport of the tubular goods through the spreader.

Bezüglich der Anordnung der Treibrollen wird es bevorzugt, wenn zwei der Treibrollen beidseits der durch die Führungsrolle und die Stützrolle definierten Ebene vorgesehen sind, deren Drehachsen parallel zu dieser Ebene verlaufen. Man wählt also eine Anordnung der Treibrollen senkrecht zu den Stütz- und Führungsrollen, so daß die Führungsrollen über den Umfang der Treibrollen sich an der Stützrolle abstützen.With regard to the arrangement of the drive rollers, it is preferred if two of the drive rollers are provided on both sides of the plane defined by the guide roller and the support roller, the axes of rotation of which run parallel to this plane. So you choose an arrangement of the drive rollers perpendicular to the support and guide rollers, so that the guide rollers are supported on the support roller over the circumference of the drive rollers.

Eine wichtige Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß an jeder Seite des Rahmens ein eigener Antrieb für die Treibrollen dieser Seite vorgesehen ist. Dadurch wird eine Änderung der Arbeitsbreite des Breithalters wesentlich erleichtert.An important embodiment of the invention is characterized in that a separate drive for the drive rollers of this side is provided on each side of the frame. This makes it much easier to change the working width of the spreader.

Für den kraft- und reibschlüssigen Eingriff der Rollen aneinander wird bevorzugt, wenn die Rollen an ihren Umfängen Schrägflächen zur reibschlüssigen Kraftübertragung zwischen den Rollen haben.For the non-positive and frictional engagement of the rollers with one another, it is preferred if the rollers have inclined surfaces on their circumferences for the frictional force transmission between the rollers.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels näher erläutert, aus dem sich weitere wichtige Merkmale ergeben.The invention is explained in more detail below on the basis of an exemplary embodiment from which further important features result.

Der gezeigte Breithalter, auch Flachbreithalter genannt, ist an der Einlaufseite einer Mercerisiermaschine angeordnet. Vgl. Fig. 1. Er besteht aus einem portalförmigen Rahmen 1, der im wesentlichen U-förmig ist, wobei die beiden U-Schenkel durch einen gegenseitigen Abstand voneinander einnehmende parallel zueinander angeordnete Gestellseiten 1a und 1b ausgebildet sind. Die beiden Gestellseiten 1a, 1b werden durch eine Quertraverse 2 miteinander verbunden.The spreader shown, also called flat spreader, is arranged on the inlet side of a mercerizing machine. See Fig. 1. It consists of a portal-shaped frame 1, which is substantially U-shaped, the two U-legs are formed by mutually spaced mutually spaced frame sides 1a and 1b. The two sides of the frame 1a, 1b are connected to one another by a crossbar 2.

Zwischen den beiden Gestellseiten 1a, 1b ist ein Verwindungsgestell 3 angeordnet, welches einen Verstellantrieb zur Breitenverstellung aufweist. Hierzu ist an der einen Seite ein Motor 4 angeordnet, der in nicht näher dargestellter Weise eine im Inneren des Verwindungsgestells 3 angeordnete Spindel 5 drehend antreibt.Between the two frame sides 1a, 1b a torsion frame 3 is arranged, which has an adjustment drive for width adjustment. For this purpose, a motor 4 is arranged on one side, which rotates a spindle 5 arranged in the interior of the torsion frame 3 in a manner not shown in detail.

In jedem Flachbreithalter 7a, 7b ist jeweils (nicht dargestellt) eine Spindelmutter angeordnet, welche von der Spindel 5 durchgriffen wird. Durch Drehantrieb des Motors 4 werden damit die Flachbreithalter 7a, 7b in den Pfeilrichtungen 6 verstellt.In each flat spreader 7a, 7b, a spindle nut is arranged (not shown), which is penetrated by the spindle 5. By rotating the motor 4, the flat spreader 7a, 7b are thus adjusted in the arrow directions 6.

Die Verstellung erfolgt so, daß die Flachbreithalter 7a, 7b immer genau parallel zueinander liegen.The adjustment is made so that the flat spreader 7a, 7b are always exactly parallel to each other.

In ihrem oberen Ende sind die Flachbreithalter 7a, 7b über eine Lagerstelle 28 mit jeweils einer Verbindungslasche 10 verbunden, wobei die beiden Verbindungslaschen in einer weiteren Lagerstelle 29 gelenkig miteinander verbunden sind. Die Verbindungslaschen bilden also eine Zwangsführung für eine auflaufende Warenbahn 11, so daß verhindert wird, daß die Warenbahn in diesem Bereich zwischen den Flachbreithaltern 7a, 7b durchhängt oder einen Bauch bildet. Die Warenbahn 11 wird hierbei in Pfeilrichtung 9 transportiert.In their upper end, the flat spreader bars 7a, 7b are connected via a bearing point 28 to a connecting plate 10, the two connecting plates being articulated to one another in a further bearing point 29. The connecting tabs thus form a positive guide for an ascending web 11, so that the web is prevented from sagging in this area between the flat spreader 7a, 7b or forming a belly. The web 11 is transported in the direction of arrow 9.

Fig. 1 zeigt den großen Verstellbereich des Verbindungsgestells 3 wo gezeigt ist, daß die Flachbreithalter 7a, 7b bis zu einer Stellung 7a′, 7b′ zusammengefahren werden können, wobei eine minimale Warenbreite von z. B. 270 mm erreicht werden kann und eine maximale Warenbreite entsprechend den konstruktiven Gegebenheiten. Wichtig ist also hier, daß minimale Warenbreite erreicht werden können, weil die vorher beschriebenen, zum Stand der Technik gehörenden teleskopierbaren Stangen entfallen können. Die minimale Warenbreite ist eigentlich nur dadurch begrenzt, daß sich dann in der eingefahrenen Stellung (zusammengefahrene Stellung) die beiden einander gegenüberliegenden Flachbreithalter 7a, 7b berühren.Fig. 1 shows the large adjustment range of the connecting frame 3 where it is shown that the flat spreader 7a, 7b can be moved up to a position 7a ', 7b', a minimum width of z. B. 270 mm can be achieved and a maximum fabric width according to the design conditions. It is therefore important here that the minimum width of the goods can be achieved because the telescopic rods described above and belonging to the prior art can be dispensed with. The minimum width of the goods is actually only limited by the fact that in the retracted position (retracted position) the two flat spreaders 7a, 7b lying opposite one another touch.

Der Einfachheit halber wird im folgenden nur die eine Seite der Anordnung nach Fig. 1 beschrieben, weil die gesamte Anordnung symmetrisch zur Mittellinie 8 ist. Die im folgenden gegebene Beschreibung gilt also für den gegenüberliegenden Teil z. B. für den Flachbreithalter 7b in gleicher Weise.For the sake of simplicity, only one side of the arrangement according to FIG. 1 is described below, because the entire arrangement is symmetrical with the center line 8. The description given below applies to the opposite part of z. B. for the flat spreader 7b in the same way.

Die Fig. 1 zeigt, daß jeder Flachbreithalter 7 einen Kettenabtrieb 12 trägt, wobei eine Kette über Umlenkrollen und Führungsrollen (Vergleiche hierzu Fig. 2) Triebrollen 18 antreibt.1 shows that each flat spreader 7 has a chain drive 12 carries, with a chain drives pulleys 18 over pulleys and guide rollers (see Fig. 2).

Jeder Flachbreithalter 7 weist in gegenseitigem Abstand übereinanderliegend jeweils eine Lagerplatte 14 auf, wobei auf der Lagerplatte drei Rollen drehbar und unverschiebbar angeordnet sind, nämlich Führungsrollen 15,16, und eine Stützrolle 17.Each flat spreader 7 has a bearing plate 14 lying one above the other at a distance from one another, three rollers being rotatably and non-displaceably arranged on the bearing plate, namely guide rollers 15, 16, and a support roller 17.

Wie in Fig. 1 schematisiert dargestellt, greift in den Zwischenraum zwischen den Rollen 15,16,17 jeweils eine Triebrolle 18 an, die über eine Antriebswelle und ein zugeordnetes Kettenrad von dem Kettenantrieb 12 drehend angetrieben wird. Der Kettenantrieb 12 ist Teil eines Lagergestells 21a, 21b, wobei dieses Lagergestell 21 fest mit der besagten Spindelmutter auf dem Verbindungsgestell 3 angeordnet ist.As shown schematically in FIG. 1, a drive roller 18 engages in the space between the rollers 15, 16, 17, which is rotatably driven by the chain drive 12 via a drive shaft and an associated chain wheel. The chain drive 12 is part of a bearing frame 21a, 21b, this bearing frame 21 being fixedly arranged with the said spindle nut on the connecting frame 3.

Die alleinige Verbindung zwischen dem Lagergestell 21 und dem breiten verstellbaren Flachbreithalter 7 erfolgt allein über die drehend angetriebenen Triebrollen 18.The sole connection between the storage frame 21 and the wide, adjustable flat spreader 7 is made solely via the rotatably driven drive rollers 18.

Dadurch wird stets gewährleistet, daß der Flachbreithalter 7 einen genau definierten Abstand zum Lagergestell 21 aufweist und hierdurch wird die geometrische Zuordnung stets aufrechterhalten ohne daß man jetzt teleskopierbare Verbindungsstangen benötigt, die den einen Flachbreithalter dem gegenüberliegenden Flachbreithalter verbinden.This always ensures that the flat spreader 7 is at a precisely defined distance from the storage frame 21 and as a result the geometric assignment is always maintained without the need now for telescopic connecting rods which connect the one flat spreader to the opposite flat spreader.

Der Transport der Warenbahn erfolgt derart, daß die Warenbahn 11 über nicht angetriebene Führungsrollen 13 über den Flachbreithalter 7 läuft, dort über die Rollen 15,16,17 geführt wird und weil die Triebrolle 18 jeweils in den Zwischenraum zwischen den Führungsrollen 15,16,17 angreift erfolgt dort der kraftschlüssige Antrieb der Warenbahn über die nicht direkt angetriebenen Rollen 15,16,17.The web is transported in such a way that the web 11 runs over non-driven guide rollers 13 over the flat spreader 7, is guided there over the rollers 15, 16, 17 and because the drive roller 18 in each case into the space between the guide rollers 15, 16, 17 there attacks the non-positive drive of the web via the non-directly driven rollers 15, 16, 17.

Dadurch daß stets an einem Flachbreithalter mindestens zwei im Abstand voneinander angeordnete Lagerplatten 14 mit zugeordneten Rollen 15,16,17 vorgesehen sind könnte es auch sein, daß man entweder die obere Führungsrolle 15 bei der oberen Lagerplatte 14 entfallen läßt und bei der unteren Lagerplatte die Führungsrolle 16 oder umgekehrt, bei der oberen Lagerplatte 14 die Führungsrolle 16 und bei der unteren Lagerplatte 14 die untere Führungsrolle 15.The fact that at least two spaced-apart bearing plates 14 with associated rollers 15, 16, 17 are always provided on a flat spreader, it could also be the case that either the upper guide roller 15 in the upper bearing plate 14 is omitted and the guide roller in the lower bearing plate 16 or vice versa, the guide roller 16 for the upper bearing plate 14 and the lower guide roller 15 for the lower bearing plate 14.

Fig. 2 zeigt die Seitenansicht des Breithalters nach Fig. 1, und zwar von der rechten Seite her gesehen, wobei erkennbar ist, daß die Warenbahn 11 über die relativ schmal ausgebildete Verbindungslasche 10 auf dem Flachbreithalter 7 läuft. An der Unterseite nach Durchlauf über den Flachbreithalter 7 wird die Warenbahn um die Umlenkrolle 30 umgelenkt, läuft hier über eine weitere Rolle 31 (Vergleiche Fig. 3), wird dort in Pfeilrichtung 34 nach oben gelenkt, läuft dort in Pfeilrichtung 35 um eine obere Umlenkrolle 33 hinüber und läuft dann über eine untere Umlenkrolle 32, wo sie wiederum umgelenkt wird. Die Warenbahn 11 läuft also mäanderförmig durch ein nicht näher dargestelltes Behandlungsbad.Fig. 2 shows the side view of the spreader according to Fig. 1, seen from the right side, whereby it can be seen that the web 11 runs over the relatively narrow connecting tab 10 on the flat spreader 7. On the underside after passing through the flat spreader 7, the web is deflected around the deflection roller 30, runs here via a further roller 31 (see FIG. 3), is steered upward there in the direction of arrow 34, runs there in the direction of arrow 35 around an upper deflection roller 33 over and then runs over a lower deflection roller 32, where it is in turn deflected. The web 11 thus runs in a meandering shape through a treatment bath, not shown.

Die Fig. 2 zeigt ferner, daß der Kettenantrieb 12 aus einem Motor 22 besteht, der ein Antriebsrad 26 antreibt, über welches die Kette über Kettenspannräder 25 und Umlenkräder 27 in einem geschlossenen Kreislauf geführt wird. Es ist ferner erkennbar, daß die Welle 19 der Triebrolle 18 jeweils über den Kettenantrieb angetrieben ist.2 also shows that the chain drive 12 consists of a motor 22 which drives a drive wheel 26, via which the chain is guided in a closed circuit via chain tensioning wheels 25 and deflection wheels 27. It can also be seen that the shaft 19 of the drive roller 18 is driven by the chain drive.

Aus Fig. 2 ist auch erkennbar, daß das Maschinenteil 1,2 über weitere Traversenen 23,24 mit der dahinterliegenden Behandlungseinheit verbunden ist.It can also be seen from FIG. 2 that the machine part 1, 2 is connected to the treatment unit behind it via further cross members 23, 24.

Fig. 4 zeigt schematisiert die Draufsicht auf eine Lagerplatte 14, wobei noch darauf hingewiesen wird, daß parallel zur Zeichenebene der Fig. 4 unterhalb der dargestellten Rollen 15 bis 18 eine genau symmetrisch gleiche Anordnung vorgesehen ist, wie sich z. B. auch aus der Fig. 6 ergibt, wo man sieht, daß bei einer Lagerplatte 14 insgesamt zwei einander gegenüberliegende Triebrollen 18 in einander zugewandte Zwischenräume von zugeordneten Rollen 15 bis 17 eingreifen.Fig. 4 shows schematically the top view of a bearing plate 14, wherein it should also be pointed out that parallel to the plane of FIG. 4 below the rollers 15 to 18 shown, an exactly symmetrical arrangement is provided, as is the case, for. B. also from FIG. 6, where you can see that a total of two opposing drive rollers 18 in a bearing plate 14 engage in mutually facing spaces between assigned rollers 15 to 17.

Es erkennbar, daß jeweils die Führungsrollen 15,16 drehbar auf dem Flachbreithalter 7a gelagert sind und an dem Flachbreithalter oben eine dreiecksförmige Lagerplatte 14 angeschweißt ist, auf welcher drehbar die dritte Rolle 17 angeordnet ist.It can be seen that in each case the guide rollers 15, 16 are rotatably mounted on the flat spreader 7a and a triangular bearing plate 14 is welded to the flat spreader, on which the third roller 17 is rotatably arranged.

Hierbei ist wesentlich, daß die Triebrolle 18 stets einen gleichbleibenden Abstand zu den darunterliegenden und senkrecht dazu angeordneten Rollen 15,16,17 aufweist, wobei dieser Abstand fest eingestellt ist und je nach Dicke der zu transportierenden Ware verändert werden kann.It is essential here that the drive roller 18 is always at a constant distance from the underlying rollers 15, 16, 17 arranged perpendicular to it, this distance being fixed and can be changed depending on the thickness of the goods to be transported.

Die Fig. 4 zeigt ferner, daß die Mittellinien der drei Rollen 15,16,17 ein gleichschenkeliges Dreieck mit Dreiecksschenkeln 52,53 bilden.4 also shows that the center lines of the three rollers 15, 16, 17 form an isosceles triangle with triangular legs 52, 53.

Bereits schon vorher wurde darauf hingewiesen, daß diese geometrische Anordnung zwar bevorzugt wird aber nicht notwendigerweise so beibehalten werden muß, es wäre also auch möglich, z. B. - entsprechend der vorher gehenden Darstellung - eine der Führungsrollen 15 oder 16 fallen zu lassen oder eine asymmetrische Anordnung zu machen, wobei immer nur stets sichergestellt werden muß, daß die beiden Führungsrollen 15,16 in der Grundlinie des Dreiecks liegen und die innere Stützrolle 17 kann dann auch in der Spitze eines ungleichschenkeligen Dreiecks liegen.It has already been pointed out beforehand that this geometrical arrangement is preferred but does not necessarily have to be retained in this way. B. - according to the previous illustration - to drop one of the guide rollers 15 or 16 or to make an asymmetrical arrangement, it always only being necessary to ensure that the two guide rollers 15, 16 lie in the base line of the triangle and the inner support roller 17 can then also lie in the tip of an unequal leg triangle.

Wichtig ist also stets nur, daß ein Zwischenraum zwischen den drei Rollen 15,16,17 geschaffen wird, in den die Triebrolle 18 mit ausreichender Tiefe eingreift, so daß dort ein kraftschlüssiger Kontakt und eine Umlenkung d.h. also die Bildung von Schrägflächen, zur Führung der Warenbahn 11 definiert werden.It is therefore only important that an intermediate space is created between the three rollers 15, 16, 17, in which the drive roller 18 engages with sufficient depth so that there is a non-positive contact and a deflection i.e. thus the formation of inclined surfaces for guiding the web 11 can be defined.

Die Fig. 5 zeigt das Eindringen der beiden einander gegenüberliegenden Treibrollen 18 in den Zwischenraum zwischen den Rollen 15,16,17, wobei die Rollen 16 nicht sichtbar unterhalb der Führungsrollen 15 angeordnet sind.5 shows the penetration of the two opposing drive rollers 18 into the space between the rollers 15, 16, 17, the rollers 16 not being arranged underneath the guide rollers 15.

Die Ware wird in Pfeilrichtung 46. transportiert. Die Schrägflächen 36,37 der Rollen liegen zugeordnete Schrägflächen 38,39 der TRiebrolle 18 gegenüber. daß dadurch Berührungsflächen 41,42,43 gebildet werden.The goods are transported in the direction of arrow 46. The inclined surfaces 36, 37 of the rollers lie opposite assigned inclined surfaces 38, 39 of the drive roller 18. in that contact surfaces 41, 42, 43 are formed.

Man erkennt, daß die Triebrolle 18 eine relativ kurze Schrägfläche 39 mit einer zugeordneten Schrägfläche der Rolle 17 einschließt, wobei die beiden Schrägflächen genau parallel zueinander sind und einen gegenseitigen Abstand voneinander aufweisen.It can be seen that the drive roller 18 includes a relatively short inclined surface 39 with an associated inclined surface of the roller 17, the two inclined surfaces being exactly parallel to one another and being at a mutual distance from one another.

Die Spitze 40 der Triebrolle 18 ist abgerundet, um eine starke Abknickung der Waren zu vermeiden. An die Spitze 40 schließt sich eine lange Schrägfläche 38 an, der eine zugeordnete Berührungsfläche 41 der Führungsrolle 15 gegenüber steht.The tip 40 of the drive roller 18 is rounded in order to avoid a sharp kinking of the goods. A long inclined surface 38 adjoins the tip 40, which is opposed by an associated contact surface 41 of the guide roller 15.

Der oberen Schrägfläche 39 ist eine zugeordnete Berührungsfläche 42 der Rolle 17 zugeordnet.An associated contact surface 42 of the roller 17 is assigned to the upper inclined surface 39.

Durch die Bildung dieser beiden Berührungszonen, nämlich der Zonen 39,42 und 38,41 wird also der kraftschlüssige Transport der Warenbahn in Pfeilrichtung 46 gewährleistet.The formation of these two contact zones, namely zones 39, 42 and 38, 41 ensures that the material web is non-positively transported in the direction of arrow 46.

Nachdem die Anordnung genau streng symmetrisch zu der Mittellinie 44 ist, kommt es hierbei zu einem geraden, verzugsfreien Transport der Warenbahn 11 über den jeweiligen Flachbreithalter 7a, 7b.After the arrangement is exactly strictly symmetrical to the center line 44, there is a straight, distortion-free transport of the web 11 over the respective flat spreader 7a, 7b.

An seinem vorderen Teil 45 ist der Flachbreithalter 7 abgerundet, um hier auch wiederum eine scharfe Abknickung der Warenbahn 11 zu vermeiden.The flat spreader 7 is rounded on its front part 45, in order to avoid a sharp bend in the material web 11.

Im Flachbreithalter 7 ist eine Ausnehmung 47 vorgesehen (Vergleiche Fig. 4 und 5) in welcher die Führungsrollen 15,16 versenkt gelagert sind.In the flat spreader 7, a recess 47 is provided (see FIGS. 4 and 5) in which the guide rollers 15, 16 are sunk.

Die Fig. 6 zeigt eine um 90° gedrehte Darstellung, nämlich die Draufsicht auf die Anordnung in Fig. 4 in Pfeilrichtung VI, wobei erkennbar ist, daß die Ausnehmung 47 genau symmetrisch gegenüberliegend in der Lagerplatte 14 vorgesehen ist.FIG. 6 shows a representation rotated by 90 °, namely the top view of the arrangement in FIG. 4 in the direction of arrow VI, wherein it can be seen that the recess 47 is provided in the bearing plate 14 in exactly symmetrical opposite relationship.

Die Fig. 7 zeigt einen Schnitt gemäß der Linie VII-VII durch den Flachbreithalter 7 mit der Lagerplatte 14. Hierbei ist erkennbar, daß die einander gegenüberliegenden Führungsrollen 15 über Kugellager 49 in dem Flachbreithalter 7 drehbar gelagert sind und die Führungsrollen 15 durch eine Schraube 50 gesichert sind.Fig. 7 shows a section along the line VII-VII through the flat spreader 7 with the bearing plate 14. It can be seen that the opposing guide rollers 15 are rotatably mounted in the flat spreader 7 via ball bearings 49 and the guide rollers 15 by a screw 50 are secured.

Am hinteren Teil ist der Flachbreithalter 7 mit der Lagerplatte 14 verbunden, die ihrerseits ein Kugellager 48 trägt, in dem die beiden Stützrollen 17 drehbar gelagert sind.At the rear part of the flat spreader 7 is connected to the bearing plate 14, which in turn carries a ball bearing 48 in which the two support rollers 17 are rotatably mounted.

In Fig. 8 ist erkennbar, daß weitere Führungsrollen 13 über entsprechende Bolzen 51 drehbar in dem Flachbreithalter 7 gelagert sind, um einen reibungsarmen Warentransport zu gewährleisten.In Fig. 8 it can be seen that further guide rollers 13 are rotatably mounted in the flat spreader 7 via corresponding bolts 51 in order to ensure low-friction transport of goods.
