Claim:
A method for profiling a fibrous web in a multiroll calender, the multiroll calendar having an upper set or stack of rolls having a lowermost roll, and the multiroll calender having a lower set or stack of rolls having an uppermost roll, and the multiroll calender having a reversing nip which does not profile the web formed between the lowermost roll and the uppermost roll, the method comprising the steps of: profiling a first side of the web in the upper set or stack of rolls having at least one first calendering nip which is formed in a cross-direction of the web between two rolls and which profiles the first side of the web in the cross-direction of the web by regulating distribution of load to the first side in the nip in a cross-machine direction; profiling a second side of the web in the lower set or stack of rolls having at least one second calendering nip which is formed in the cross-direction of the web between two rolls and which profiles a second side of the web opposite to the first side in the cross-direction by regulating distribution of load to the second side in the nip in the cross-machine direction; and passing the web through the reversing nip which does not profile the web and, wherein the first side is profiled in the first calendering nip and the second side of the web is profiled in the second calendering nip before passing the web through the reversing nip.
