摘要： The invention relates to an apparatus for 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 wherein 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.

摘要： A press section in a machine for manufacturing a web of fibrous material, comprising a shoe press with extended press nip, the shoe press having a counter roll with a cylindrical press body; a press shoe with a concave surface for cooperation with the press body; an impermeable belt running through the press nip in sliding contact with the press shoe; a clothing running in a loop around guide rolls and through the press nip in contact with the web, and being capable of receiving and carrying liquid along with it; a movable heat transfer means for continuous transfer of heat to the web in the extended press nip; and a heat source for heating the heat transfer means. According to the invention the counter roll comprises a sleeve that forms the heat transfer means and encloses the press body. The invention also relates to a shoe press, a press section with a roll press, and treatment sections with roll and shoe calendars with sleeves of the type described.
