ABSTRACT:
In a calender assembly for treating a web of material (1) in a nip (4) formed by a pair of press rolls (2, 3), at least one roll (3) is heated. In front of and/or behind the nip (4) there is at least one additional roll (8, 9, 14) which can be displaced into the path of the web of material (1) in such a way that the angle of wrap of the web of material (1) at the heated press roll (3) increases. In this way, easy and quick introduction of the web of material is made possible. Further, the heat losses of the heated roll are reduced.
