Abstract

L'invention concerne un cylindre à déformation de flexion. La compensation de déformation du cylindre 10 est réalisée en au moins deux zones alpha , beta commandables de façon indépendante et situées entre l'axe fixe 14 du cylindre 10 et la coquille tournante 12 de ce dernier, la zone alpha étant utilisée pour compenser respectivement la flexion due au poids propre du cylindre et la zone beta pour compenser la flexion due à la charge de pression linéaire de l'interstice N de calandre. Application: cylindres pour calandres de machines à papier.
