Zusammenfassung:Calender for the treatment of a paper web including a roll stack of at least three rolls and with least one double-sort nip. The double-soft nip(s) are formed by two rolls, each with an elastic surface layer. At least one of the rolls forming the double-soft nip is heated. In a process using the calendar to treat a material web, the web is introduced into a roll stack having at least two rolls forged with an elastic surface layer over a rigid core, agglomerated in an elastic doublesoft nip between the two rolls, heated to introduce energy into the material web and promote agglomerating, and smoothed in the elastic double-soft nip.
