Abstract
The invention relates to a method for operating a calender, comprising a cylindrical heated roll and a flexible belt surrounding a stationary support beam which supports at least one actuator which may urge a concave load shoe against the heated roll by the flexible belt to form an extended and heated nip through which a fiber web passes to be calendered and a separating mechanism for having at least one of the rolls movable into and away from the nip characterized in that the flexible belt is a flexible tubular jacket which forms a part of an enclosed shoe roll such that the ends of the jacket have end walls mounted thereto, which end walls are rotatably mounted in relation to the support beam, and in that at least one of the end walls is driven by a drive arrangement which drive arrangement may be activated to drive the end walls and thereby also the jacket independently of its position in relation to the fiber web or the heated roll.
