Description

Die Erfindung bezieht sich auf einen Mehrwalzenkalander, insbesondere Vierwalzenkalander, zum beidseitigen Belegen eines Gewebes mit einer Kautschukschicht, dessen Walzen in I-Form angeordnet sind, wobei die obere Walze des ersten Walzenpaares 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 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 Covering a fabric on both sides with a rubber layer, the rollers of which are arranged in an I-shape are, 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 link adjustable in the vertical direction are mounted and the lowermost roller of the second pair of rollers can be adjusted in the vertical direction with respect to the roller above is.

Der Erfindung liegt die Aufgabe zugrunde, einen Kalander dieser Art in der Lagerung der untersten Walzen so auszubilden, daß beispielsweise eine Cordgewebebahn, wie sie zur Herstellung von Reifenrohlingen verwendet wird, mit einer gleichmäßigen Kautschukbeschichtung auf 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 is based on the object of a calender of this type in the storage of the lowest Rollers to train so that, for example, a cord fabric web, as they are for the production of green tires should be provided with an even rubber coating on both sides can. This is done according to the invention in that the lowermost roller of the second roller pair is within the backdrop opposite the roller above it is also designed to be adjustable at an angle is.

Durch die erfindungsgemäße Maßnahme wird die Durchbiegung der beiden Walzen des zweiten Walzenpaares als Folge des Materialdruckes im Walzenspalt ausgeglichen, und es lassen sich gleichmäßige Beschichtungen erreichen.The measure according to the invention reduces the deflection of the two rollers of the second roller pair 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 Vierwalzenkalanders in 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 in I-shape with 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 2 ausgeglichen. Die Schrägverstellung wird mit den Getrieben 6 und 7 durchgeführt.The deflection of the roller 1 is caused by an inclination with respect to the stationary roller 2 balanced. The skew adjustment is carried out with the gears 6 and 7.

Die Veränderung des Spaltes zwischen den Walzen 2 und 3 geschieht durch gemeinsames 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 the rolls 2 and 3 is done by joint raising and lowering of the rollers 3 and 4, which in one Setting 8 are stored. The gate 8 can be lifted by means of a gear 9 mounted outside the same or be 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 Walze 3 und 4 ist die Walze 4 gegenüber der darüberliegenden Walze 3 innerhalb der Kulisse 8 schräg verstellbar. Die Schrägverstellung wird mit Hilfe von Getrieben 11 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 8. The inclination is done with the help of gears 11 and 12 causes.

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