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.
