A roll whose bend can be controlled has support elements which are designed as ring elements with an annular pocket and an annular pressure surface. The interior space enclosed by the ring element is connected to an outlet line having an adjustable throttle element. By appropriately adjusting the throttle element, any arbitrary intermediate pressure can be maintained in the interior space. Therefore, a wide adjustment range for the support force is possible, and needs only a feed line for the pressure medium and an outlet line. In this way, relatively large and relatively small path loads can be processed in the roll gap without a major structural change.
Cette invention concerne un rouleau à flexion commandée dont les éléments support se présentent sous la forme d'anneaux à gorge annulaire et surface de pression également annulaire. L'espace intérieur délimité par l'anneau est raccordé à une canalisation d'évacuation à étranglement réglable. En réglant judicieusement l'étranglement, on peut maintenir une pression intermédiaire arbitraire dans l'espace intérieur susmentionné. Ainsi, une large plage de réglage de la force de soutien est rendue possible avec une seule canalisation d'amenée de liquide sous pression et une canalisation d'évacuation. Ce montage permet de traiter des matériaux relativement larges et relativement étroits sans modification structurale majeure.
