ABSTRACT:
The invention relates to a method and an apparatus calendering a fiber web, wherein the fiber web passes through an extended and heated nip, said nip being formed on one side by a cylindrical heated roll and on the other side by a flexible tubular jacket which is pressed against the heated roll by means of a concave load shoe, said tubular jacket surrounding a stationary support beam which supports at least one actuator which may urge said load shoe and said flexible tubular jacket against said heated roll, and wherein the extension of the load shoe in the axial extension is less than the axial extension of the jacket and the heated roll such that when the load shoe is urged against the heated roll there will be formed tapered sections at each side end of the jacket within the nip characterised in that said tapered section are substantially covered by said fiber web such that a small strips of the fiber web at each edge is not calendered in said extended nip.
