A calender which includes a deflection-controlled roller with a rotating hollow cylinder and a non-rotating cross-head. Hydrostatic supporting elements on the cross-head can be radially displaced towards the inside circumference of the hollow cylinder, and have bearing pockets in their contact surfaces. The position of supporting elements are controlled using a cylinder space with a small cross-section. When there is a problem with the web, the cylinder spaces can all be hydraulically relieved, eliminating the contact pressure and therefore the exertion of force by the supporting elements.
Calandre (K) comprenant un cylindre (100) pouvant être régulé en flexion muni d'un cylindre creux tournant (1) et d'une traverse non rotative (3). Sur la traverse (3) sont montés des éléments supports hydrostatiques (14) déplaçables radialement contre le pourtour intérieur (4) du cylindre creux (1) et présentant, dans leurs surfaces d'appui (24), des poches supports hydrostatiques (39). Les éléments supports (14) sont pressés par une chambre cylindrique (49) de faible section transversale. Toutes les chambres cylindriques (49) peuvent être déchargées hydrauliquement dans le cas d'un défaut affectant la bande calandrée, de sorte qu'il n'existe plus de pression, ni de force appliquées par les éléments supports (14).
