Patent

CA 2116599

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.

Dans la calandre de traitement d'un matériau en bande continue (1), à la ligne de contact entre une paire de rouleaux de presse (2, 3), au moins un rouleau (3) est chauffé. € l'avant et/ou à l'arrière de la ligne de contact (4), il y a au moins un rouleau supplémentaire (8, 9, 14) qui peut être déplacé dans la trajectoire de la bande continue de matériau (1) de manière à pouvoir agrandir l'angle d'enroulement de la bande (1) au droit du rouleau chauffé. Il est donc possible d'introduire rapidement et facilement la bande de matériau. De plus, les pertes de chaleur du rouleau chauffé sont réduites.
