Description

Die Erfindung bezieht sich auf einen Mehrwalzenkalander, insbesondere Vierwalzenkalander, zum beidseitigen Belegen eines Gewebes mit einer Kautsqhukschicht, dessen Walzen in I-Forai angeordnet sind, wobei die obere Walze des ersten Walzcnpaares gegenüber der darunterliegenden Walze in senkrechter Richtung und schräg verstellbar ist, die beiden Walzen des unteren zweiten Walzenpaares in einer in senkrechter Richtung verstellbaren gemeinsamen Kulisse gelagert sind und die unterste Walze ίο des zweiten Walzenpaares gegenüber der darüberliegenden Walze in senkrechter Richtung verstellbar ist.The invention relates to a multi-roll calender, in particular a four-roll calender, for double-sided covering of a fabric with a rubber layer, whose rollers are arranged in I-Forai are, with the upper roller of the first roller pair opposite the roller below in a vertical position Direction and inclination is adjustable, the two rollers of the lower second roller pair in a common setting adjustable in the vertical direction are mounted and the lowermost roller ίο of the second pair of rollers can be adjusted in the vertical direction with respect to the roller above is.

Der Erfindung Hegt die Aufgabe zugrunde, einen Kalander dieser Art in der Lagerung der untersten «5 Walzen so auszubilden, daß beispielsweise eine Cordgewebebahn, wie sie zur Herstellung von Reifenrohlingen verwendet wird, mit einer gleichmäßigen Kautschufcbeschichtüng ai i beiden Seiten versehen werden kann. Dies geschieht erfindungsgemäß dadurch, daß die unterste Walze des zweiten Walzenpaares innerhalb der Kulisse gegenüber der darüberliegenden Walze zusätzlich noch schräg verstellbar ausgebildet ist.The invention Hegt form the object of a calender of this type in the storage of the lowest "5 rolls so that, for example a Cordgewebebahn, as used for the production of green tires, with a uniform Kautschufcbeschichtüng ai i both sides can be provided. This is done according to the invention in that the lowermost roller of the second roller pair is also designed to be inclinedly adjustable within the link relative to the roller above.

Durch die erfindungsgemäße Maßnahme wird die Durchbiegung der beiden Walzen des zweiten WaI-renpaares als Folge des Materialdruckes im Walzenspalt ausgeglichen, und es lassen sich gleichmäßige Beschichtungen erreichen.The measure according to the invention is the Deflection of the two rolls of the second pair of rolls balanced as a result of the material pressure in the nip, and it can be even Achieve coatings.

Ein Ausführungsbeispiel des Kalanders ist in der Zeichnung veranschaulicht. Die Zeichnung zeigt eine Ansicht eines Vierwalzenkalandere i.. I-Form mit den Kalanderwalzen 1 bis 4.An embodiment of the calender is illustrated in the drawing. The drawing shows a View of a four-roll calender i .. I-shape with the Calender rolls 1 to 4.

Die Einstellung des Spaltes zwischen den Walzen 1 und 2 erfolgt durch Anheben bzw. Absenken der Walze 1 relativ zu der Walze 2 mit Hilfe eines Getriebes 5.The adjustment of the gap between the rollers 1 and 2 is done by raising or lowering the Roll 1 relative to roll 2 with the aid of a gear 5.

Die Durchbiegung der Walze 1 wird durch Schrägverstellung gegenüber der ortsfest gelagerten Walze Ä ausgeglichen. Die Schrägverstellung wird mit den Ge- 4,> trieben 6 und 7 durchgeführt.The deflection of the roller 1 is compensated for by adjusting it at an angle with respect to the stationary roller Ä. The diagonal adjustment is carried out with gears 4,> gears 6 and 7.

Die Veränderung des Spaltes zwischen den Walzen 2 und 3 geschieht durch genieinsames Anheben bzw. Absenken der Walzen 3 und 4, welche in einer Kulisse 8 gelagert sind. Die Kulisse 8 kann mittels eines außerhalb derselben gelagerten Getriebes 9 gehoben bzw. abgesenkt werden.The change in the gap between rollers 2 and 3 is done by ingenious lifting or lowering of the rollers 3 and 4, which are mounted in a link 8. The backdrop 8 can by means of a gear 9 mounted outside the same can be raised or lowered.

Der Spalt zwischen den Walzen 3 und 4 kann durch Verstellung der Walze 4 in senkrechter Richtung verändert werden. Dazu ist ein Getriebe 10 vorgesehen, welches die Walze 4 unabhängig von der Walze 3 anhebt bzw. absenkt.The gap between the rollers 3 and 4 can be changed by adjusting the roller 4 in the vertical direction will. For this purpose, a transmission 10 is provided which lifts the roller 4 independently of the roller 3 or lowers.

Zum Ausgleich der Durchbiegung der Wal?e 3 und 4 ist die Walze 4 gegenüber der darüberliegenden Walze 3 innerhalb der Kulisse 3 schräg verstellbar. Die Schrägversteilung wird mit Hilfe von Getrieben" Il und 12 bewirkt.To compensate for the deflection of the rollers 3 and 4, the roller 4 is opposite the one above it Roller 3 can be adjusted at an angle within the backdrop 3. The inclined pitch is done with the help of gears " Il and 12 causes.

Die schrägverstellbare Ausbildung an unteren Walzenpaaren ist beispielsweise auch bei einem F-Ka!ander vorteilhaft anwendbar.The diagonally adjustable design on the lower pairs of rollers is also used, for example, in an F-Ka! Other advantageously applicable.

Der beschriebene Vierwalzenkalander eignet sich in bestem Maße zum beiderseitigen Beschichten von Cordgewebe, da zur Erzielung einer in der Dicke gleichmäßigen Cordgewebebahn die beiden Schichten aus einer Kautschukmischung gleich dick sein müssen. Dies kann dadurch erreicht werden, daß durch Schrägverstellung der miteinander zusammenarbeitenden unteren Walzen das Durchdrücken der Walzen ausgeglichen wird.The four-roll calender described is ideally suited for coating on both sides Cord fabric, because the two layers are used to achieve a cord fabric web of uniform thickness made of a rubber mixture must be of the same thickness. This can be achieved by Inclination of the cooperating lower rollers pushing the rollers through is balanced.
