Abstract:
A calender device for calendering a fibrous web, said calender device comprising:a stationary support beam; a flexible tubular jacket surrounding the stationary support beam and having a pair of opposed ends; a heated counter element arranged on the opposite side of the flexible tubular jacket from the support beam such that the fibrous web is advanced between the flexible tubular jacket and the heated counter element; a load element supported on the stationary support beam opposite the heated counter element for pressing the flexible tubular jacket against the heated counter element and thereby calendering the fibrous web interposed therebetween; an end wall rotatably supported adjacent to each end of the flexible tubular jacket, each end of said flexible tubular jacket being securely supported by the respective end wall; and a drive arrangement in operative engagement with each end wall, the drive arrangements being in communication with each other so as to be capable of synchronously rotating the end walls to thereby cause rotation of the flexible tubular jacket in a position-independent manner with respect to the heated counter element.
