Abstract: A relief and raising device arrangement in a multinip calender or calender stack, in which upon a stationarily rotatable lower roll are mounted two or more superimposed rolls which are pivotably attached by arms to the calender body and in which each roll has its individual relief device attached to a common raising device. The relief devices are so attached to the raising device that the raising device will through the pneumatically regulated relief device constantly be in connection with the roll and that an adjustable free spacing for movement of the relief devices increases in the downward direction. The raising device is preferably a rod movable in vertical direction and attached to the lower or upper part of the calender body.
