One end of the roll neck 11 of each roll 2, 3 is provided with a torsionally rigid coupling 19, e.g. B. a universal joint shaft. This clutch 19 is in turn each fastened to a drive wheel 21, 22 which is rotatably mounted with respect to a side frame 26 by means of a journal 24 having roller bearings 23. Thus, both rollers 2, 3 interacting drive wheels 21, 22 and are in a positive drive connection with a fixed transmission ratio i, z. B. i = 1: 1.
A two-channel rotary inlet 27 is arranged on each of the opposite roller journals 9 and is connected to the two transport wheels 13 of a roller 2, 3 by means of two lines 28, 29.

Die Lagerarme 17 der Walzen 2, 3 sind gleich aufgebaut und jeweils an einem ersten Ende 33 mittels eines Bolzens 31 an einer Innenseite des Seitengestelles 26, 32 schwenkbar befestigt. Ein zweites Ende 34 des Lagerarmes 17 ist gabelförmig ausgebildet und mit einer schwenkbaren Gewindenuß 36 versehen. Durch die Gewindenuß 36 führt eine Einstellspindel 37 mit einem Durchmesser D 37, z. B. D37 = 12 mm, durch eine Lagerung 38 bis in die Gewindenuß 36 des zugehörigen Lagerarmes 17 der zweiten Walze 3. Die Lagerung 38 der Einstellspindel 37 besteht aus einem gestellfesten Zapfen 39, der mit zwei senkrecht zueinander stehenden Schlitzen 41, 42 versehen ist. Einer dieser beiden Schlitze 41 ist parallel zur Einstellspindel 37 verlaufend etwas breiter, z. B. mit einer Breite b41 = 14 mm, als der Durchmesser D37 der Einstellspindel 37 ausgeführt. Die Einstellspindel 37 ist ungefähr mittig mit einer axial fixierten Scheibe 43 versehen, die in dem zweiten Schlitz 42 zur axialen Sicherung der Einstellspindel 37 bezüglich des Seitengestelles 26, 32 angeordnet ist. Die Gewindenüsse 36 der Lagerarme 17 und die damit zusammenwirkende Einstellspindel 37 sind mit Rechts- und Linksgewinde versehen. Zudem weist die Einstellspindel 37 im vorliegenden Beispiel einen Verstellgriff 44 mit integriertem Stellungsanzeiger auf. Es ist auch möglich, jede Walze 2, 3 mit einer eigenen Einstellspindel 37 zu versehen. Dies ist insbesondere dann der Fall, wenn nur eine der beiden Walzen 2, 3 mit elastischen Transportelementen 10, 13 ausgestattet ist.The bearing arms 17 of the rollers 2, 3 have the same structure and each at a first end 33 by means of a Bolt 31 on an inside of the side frame 26, 32 pivotally attached. A second end 34 of the Bearing arm 17 is fork-shaped and with a pivotable threaded nut 36 provided. Through the Threaded nut 36 guides an adjusting spindle 37 with a Diameter D 37, e.g. B. D37 = 12 mm, by storage 38 to the threaded nut 36 of the associated bearing arm 17 of the second roller 3. The bearing 38 of the Adjustment spindle 37 consists of a frame-fixed Pin 39, the two perpendicular to each other Slits 41, 42 is provided. One of those two Slots 41 are parallel to the adjusting spindle 37 somewhat wider, e.g. B. with a width b41 = 14 mm, as the diameter D37 of the adjusting spindle 37 executed. The adjustment spindle 37 is approximate provided with an axially fixed disc 43 in the center, the in the second slot 42 for axially securing the Adjustment spindle 37 with respect to the side frame 26, 32 is arranged. The threaded nuts 36 of the bearing arms 17 and the adjusting spindle 37 interacting therewith are included Right and left hand threads. In addition, the Adjustment spindle 37 in the present example Adjustment handle 44 with integrated position indicator. It is also possible to have each roller 2, 3 with its own Adjustment spindle 37 to be provided. This is particularly so then the case if only one of the two rollers 2, 3 with elastic transport elements 10, 13 is equipped.

Die Transportelemente 10, 13 sind in Umfangsrichtung Drehmomente übertragend und in radialer Richtung elastisch, d. h. nachgiebig ausgeführt.
Die im Beispiel ausgeführten Transporträder 13 bestehen jeweils im wesentlichen aus einer Nabe 46, einem Ausgleichsring 47 und einem Transportring 48. Die Nabe 46 ist mittels der Paßfeder 14 und dem Klemmring 16 drehsteif, aber bei gelösten Klemmring 16 axial verschiebbar auf dem zugehörigen Walzenzapfen 9, 11 festgeklemmt. Auf der Nabe 46 ist der Ausgleichsring 47 in Form eines Schlauches befestigt, z. B. aufvulkanisiert. Dieser Ausgleichsring 47 ist in Umfangsrichtung Drehmomente übertragend und in radialer Richtung elastisch, d. h. zusammendrückbar ausgeführt. Dazu ist eine Schlauchwand 49 des Ausgleichsringes 47 mit nichtdargestellten Einlagen verstärkt. In einem Inneren des Ausgleichsringes 47 ist eine mit Druckmittel, beispielsweise Druckluft, Hydraulikflüssigkeit oder Polyethylenschaum, beaufschlagbare Druckkammer 51 angeordnet. Diese Druckkammer 51 ist mittels einer Bohrung 52 mit der Leitung 28, 29 und damit mit der zugehörigen Dreheinführung 27 verbunden. In einer Zuleitung 53, 54 zur Dreheinführung 27 ist für jeden Kanal ein nichtdargestelltes Druckregelventil zur Einstellung eines Druckes des Druckmittels in der jeweiligen Druckkammer 51 vorgesehen. Es ist aber auch möglich für alle Kanäle ein gemeinsames Druckregelventil anzuordnen. Diese Druckregelventile können auch mittels eines Rechners ferngesteuert geregelt werden.
The transport elements 10, 13 are torque-transmitting in the circumferential direction and are elastic, that is to say flexible, in the radial direction.
The transport wheels 13 executed in the example each consist essentially of a hub 46, a compensating ring 47 and a transport ring 48. 11 clamped. On the hub 46, the compensating ring 47 is attached in the form of a hose, for. B. vulcanized. This compensating ring 47 transmits torques in the circumferential direction and is designed to be elastic in the radial direction, ie compressible. For this purpose, a hose wall 49 of the compensating ring 47 is reinforced with inserts, not shown. A pressure chamber 51 which can be acted upon by pressure medium, for example compressed air, hydraulic fluid or polyethylene foam, is arranged in an interior of the compensating ring 47. This pressure chamber 51 is connected to the line 28, 29 and thus to the associated rotary inlet 27 by means of a bore 52. A pressure control valve (not shown) for setting a pressure of the pressure medium in the respective pressure chamber 51 is provided in a feed line 53, 54 to the rotary inlet 27 for each channel. However, it is also possible to arrange a common pressure control valve for all channels. These pressure control valves can also be controlled remotely using a computer.

Der Ausgleichsring 47 kann aber auch beispielsweise aus einem Elastomer bestehen. Es ist auch möglich den Transportring 48 mittels radial wirkender, sowohl an einer Innenseite des Transportringes 48 als auch an einer Außenseite der Nabe 46 angreifender Federn zu lagern. Ebenso ist es auch denkbar den Transportring 48 aus einem Elastomer auszubilden und auf den Ausgleichsring 47 zu verzichten.
Auf dem Ausgleichsring 47 ist der beispielsweise zweigeteilte Transportring 48 mittels zweier Klemmringe 56, 57 befestigt. Die Klemmringe 56, 57 sind mit einem konusartigen Bund 58, 59 versehen, die mit abgeschrägten Seitenflächen 61, 62 des Transportringes 48 in Umfangsrichtung reibschlüssig und in radialer Richtung formschlüssig zusammenwirken. Dazu sind die beiden Klemmringe 56, 57 in axialer Richtung mittels durch den Ausgleichsring 47 reichender Gewindeschrauben 63 verspannt. Der Transportring 48 ist im vorliegenden Beispiel mit einer Lauffläche 64 versehen. Ein Durchmesser D48, z. B. D48 = 123 mm, dieses Transportringes 48 bzw. der Lauffläche 64 ist ca. 2,5 % größer ausgeführt als ein notwendiger Nenndurchmesser dn, z. B. dn = 120 mm, zur Erzielung einer definierten Umfangsgeschwindigkeit, d. h. der Transportring 48 ist mit Voreilung ausgelegt.
The compensation ring 47 can also consist of an elastomer, for example. It is also possible to mount the transport ring 48 by means of radially acting springs which act both on an inner side of the transport ring 48 and on an outer side of the hub 46. It is also conceivable to form the transport ring 48 from an elastomer and to dispense with the compensating ring 47.
The, for example, two-part transport ring 48 is fastened on the compensating ring 47 by means of two clamping rings 56, 57. The clamping rings 56, 57 are provided with a cone-like collar 58, 59, which interact with bevelled side surfaces 61, 62 of the transport ring 48 in a frictionally locking manner in the circumferential direction and in a positive manner in the radial direction. For this purpose, the two clamping rings 56, 57 are clamped in the axial direction by means of threaded screws 63 reaching through the compensating ring 47. The transport ring 48 is provided with a running surface 64 in the present example. A diameter D48, e.g. B. D48 = 123 mm, this transport ring 48 or the running surface 64 is made about 2.5% larger than a necessary nominal diameter dn, z. B. dn = 120 mm, to achieve a defined peripheral speed, ie the transport ring 48 is designed with lead.

Es ist auch möglich, eine Mantelfläche 66 des Ballens 6 der Walzen 2, 3 in radialer Richtung elastisch und in Umfangsrichtung Drehmomente übertragend auszuführen. Dazu ist beispielsweise eine die Mantelfläche 66 des Ballens 6 bildende, als Transportelement 10 wirkende Hülse 67, z. B. ein Stahl- oder CFK-Rohr, vorgesehen, die auf der die Walzenzapfen 9, 11 bildenden durchgehenden Welle 12 mittels eines oder mehrerer Ausgleichselemente gelagert ist. Diese Ausgleichselemente können wie bei den bereits beschriebenen Transporträdern 13 aus mit Druckmittel beaufschlagbaren Schläuchen oder aus den Transporträdern 13 bestehen (Fig. 4). Dazu kann an jeder Seite der Hülse 67 ein ringförmiger Schlauch, z. B. ein Ausgleichsring 47, angebracht sein oder ein durchgehender rohrartiger Schlauch vorgesehen sein. Ebenso kann zwischen Hülse 67 und Welle 12 ein Elastomer einvulkanisiert sein oder radial wirkende Federn angeordnet sein. Im einfachsten Fall kann die Welle 12 nur mit einem Elastomer beschichtet sein und auf die Hülse 67 verzichtet werden.It is also possible to have a lateral surface 66 of the bale 6 the rollers 2, 3 elastic in the radial direction and in Circumferential direction to transmit torques. For this purpose, for example, the outer surface 66 of the Bale 6 forming, acting as a transport element 10 Sleeve 67, e.g. B. a steel or CFRP tube provided, those on which form the roll neck 9, 11 continuous shaft 12 by means of one or more Compensating elements is stored. This Compensating elements can as with the already described transport wheels 13 from with pressure medium pressurized hoses or from the transport wheels 13 exist (Fig. 4). This can be done on each side of the sleeve 67 an annular hose, e.g. B. a balance ring 47, attached or a continuous tubular Hose should be provided. Likewise, between sleeve 67 and shaft 12 vulcanized in an elastomer or radially acting springs can be arranged. In the simplest The shaft 12 can only fall with an elastomer be coated and the sleeve 67 are dispensed with.

Es ist auch möglich, nur eine der beiden Walzen 2, 3 mit einem oder mehreren elastischen Transportelementen zu versehen und deren Gegenwalze in üblicher Weise, z. B. als Stahlwalze, auszuführen. It is also possible to have only one of the two rollers 2, 3 one or more elastic transport elements provided and the counter roller in the usual manner, for. B. as a steel roller.

Die Funktionsweise des erfindungsgemäßen Zugwalzenpaares 1 ist folgendermaßen:
Zwischen den Antriebselementen, z. B. den Transporträdern 13, wird die Bahn 4 geführt. Dazu wird die Druckkammer 51 des Ausgleichsringes 47 mit einem Druckmittel beaufschlagt, wodurch die Bahn 4 mit definierter Pressung, die unabhängig von einem Achsabstand a der Walzen 2, 3 bzw. einer Dicke der Bahn 4 ist, zwischen den Transporträdern 13 gehalten wird. über die beiden Antriebsräder 21, 22 werden die Walzen 2, 3 mit den darauf befestigten Transporträdern 13 angetrieben und die Bahn 4 transportiert. Muß eine Umfangsgeschwindigkeit der Transporträder 13 verändert werden, um eine Veränderung der Länge der Bahn 4 durch veränderte Druckbedingungen oder einen veränderten Reibwert der Bahn 4 zu kompensieren, wird mittels der Einstellspindeln 37 beidseitig der Achsabstand a zwischen den beiden Walzen 2, 3 zu einem Achsabstand a' verkleinert. Dadurch werden die beiden Ausgleichsringe 47 aus ihrer zu den Walzen 2, 3 konzentrischen in eine exzentrische Lage gedrückt. Dabei wird der sich aus dem Durchmesser D48 im nichtausgelenkten Zustand ergebende Wirkradius R48 zu einen Wirkradius R48' verkleinert, womit sich auch bei gleichbleibender Drehzahl der Walzen 2, 3 die Umfangsgeschwindigkeit der Transporträder 13 verringert. Diese sich aus den beiden Wirkradien R48, R48' ergebende Differenz entspricht dem halben Betrag der Achsabstandsveränderung. Auch ist es möglich diese Veränderung des Wirkradiuses R48 nur einseitig auszuführen, was zu einer unterschiedlichen Umfangsgeschwindigkeit an den Seitenkanten der Bahn 4 führt.
In diesem Ausführungsbeispiel wird die Bahn 4 von den Transporträdern 13 gehalten und transportiert, während die Ballen 6 der Walzen 2, 3 nur als Stützelemente dienen.
Adäquat zu diesem Ausführungsbeispiel ist die Funktionsweise in der Version ohne Transporträder 13, in der die Hülse 67 der Walzen 2, 3 elastisch bezüglich der Walzenzapfen 9, 11 gelagert ist. Auch hier wird zur Veränderung der Umfangsgeschwindigkeit die Hülse 67 durch Verkleinerung des Achsabstandes a der beiden Walzen 2, 3 aus ihrer zu den Walzenzapfen 9, 11 konzentrischen Lage in eine exzentrische Lage verschoben und damit ihre Umfangsgeschwindigkeit reduziert.
Ist nur eine Walze 2, 3 mit elastischen Transportelementen versehen, bleibt bei Veränderung des Achsabstandes a der beiden Walzen 2, 3 die Umfangsgeschwindigkeit der Walze 2 mit "festen" Durchmesser konstant, während sich die Umfangsgeschwindigkeit der Walze 3 mit elastischen Transportelementen ändert. Dabei stehen die beiden Walzen 2, 3 nicht in formschlüssiger Antriebsverbindung, sondern nur die Walze 3 mit veränderbarem Durchmesser wird formschlüssig angetrieben.
The operation of the pair of pull rollers 1 according to the invention is as follows:
Between the drive elements, e.g. B. the transport wheels 13, the web 4 is guided. For this purpose, the pressure chamber 51 of the compensating ring 47 is acted upon by a pressure medium, as a result of which the web 4 is held between the transport wheels 13 with a defined pressure, which is independent of a center distance a of the rollers 2, 3 or a thickness of the web 4. The rollers 2, 3 with the transport wheels 13 fastened thereon are driven via the two drive wheels 21, 22 and the web 4 is transported. If a peripheral speed of the transport wheels 13 has to be changed in order to compensate for a change in the length of the web 4 due to changed pressure conditions or a changed coefficient of friction of the web 4, the center distance a between the two rollers 2, 3 becomes a center distance a by means of the adjusting spindles 37 on both sides 'downsized. As a result, the two compensation rings 47 are pressed out of their concentric with the rollers 2, 3 into an eccentric position. The effective radius R48 resulting from the diameter D48 in the undeflected state is reduced to an effective radius R48 ', which means that the circumferential speed of the transport wheels 13 is reduced even when the speed of rotation of the rollers 2, 3 remains the same. This difference resulting from the two effective radii R48, R48 'corresponds to half the amount of the change in the center distance. It is also possible to carry out this change in the effective radius R48 only on one side, which leads to a different peripheral speed on the side edges of the web 4.
In this embodiment, the web 4 is held and transported by the transport wheels 13, while the bales 6 of the rollers 2, 3 serve only as support elements.
Adequate to this exemplary embodiment is the mode of operation in the version without transport wheels 13, in which the sleeve 67 of the rollers 2, 3 is elastically mounted with respect to the roller journals 9, 11. Here too, in order to change the peripheral speed, the sleeve 67 is shifted from its position concentric with the roll pins 9, 11 into an eccentric position by reducing the center distance a of the two rollers 2, 3, and thus reduces its peripheral speed.
If only one roller 2, 3 is provided with elastic transport elements, the circumferential speed of roller 2 with "fixed" diameter remains constant when the axial spacing a of the two rollers 2, 3 changes, while the circumferential speed of roller 3 changes with elastic transport elements. The two rollers 2, 3 are not in a positive drive connection, but only the roller 3 with a variable diameter is driven in a positive manner.

Da die Transportelemente mit Voreilung ausgeführt sind, ist es natürlich auch möglich die Umfangsgeschwindigkeit über eine Nennumfangsgeschwindigkeit hinausgehend zu vergrößern. Since the transport elements are designed with lead, the peripheral speed is of course also possible beyond a nominal circumferential speed enlarge.
