Abstract: A multi-roll calender, supercalender, soft calender or equivalent has at least one nip (YN, PN1, KN, PN2, AN) profiling a fibrous web (W) which is being calendered. A shoe roll (1, 4, 6, 10) constitutes at least one of the calender rolls which define the nip. A shell (11, 41, 61, 101) of the shoe roll is of a composite material, and the shoe roll is provided with internal shell-loading shoes (12, 42, 43, 62, 63, 103) for profiling the shell, the nip and/or the fibrous web.

Abstract: Roll-changing apparatus for a multi-nip calender an upright part (10) of the roll-changing apparatus having at least one vertical column (11), to which at least one horizontal beam (12) and, at its lower end, a carrier part (13) belong, and a roll-changing apparatus (1) of the roll changing apparatus further including a vertically moveable lifting carriage (14) which is fitted to the vertical column. According to the invention for transporting the rolls (21,22) of the calender (2) in the lateral direction from the calender to the roll store (3) and vice versa, the roll-changing apparatus (1) can be conveyed between calender and roll store, while the lifting carriage (14) of the roll-changing apparatus (1) is immovable in the lateral direction with respect to the vertical column (11).

Abstract: A paper machine roll, in particular for a soft calender or supercalender, which includes a metal frame, roll ends, and shafts. The frame is coated with a polymer coating over at least a middle area or central region thereof while lateral regions may optionally remain uncoated. In order to equalize a difference in temperature between the roll ends and the optionally non-coated lateral regions of the metal frame, on one hand, and the coated central region area of the roll, on the other hand, an arrangement for equalizing the difference in temperature is provided by heating the roll ends and the optionally non-coated lateral regions of the metal frame.
