Abstract
A paper web is profiled in a multiroll calender which includes at least an upper set of rolls having at least one calendering nip which profiles the paper web on one side; at least one lower set of rolls having at least one calendering nip which profiles the paper web on the other side; and a reversing nip between the upper set of rolls and the lower set of rolls. Both sides of the web are profiled in calendering nips before a nip which does not profile the web.
