Abstract
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 rage 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.
Claims13
A roll for a calender having controlled bending, comprising:
- a non-rotatably mounted carrier;
- a plurality of hydrostatic support elements each having a ring-shaped support surface with at least one ring-shaped pocket in said support surface;
- a roll sleeve supported by said hydrostatic support elements against said non-rotatably mounted carrier, said support elements being disposed within said roll sleeve, said at least one pocket of each hydrostatic support element faces an inside surface of said roll sleeve, each of said plurality of hydrostatic supports elements having a pressure surface which faces said carrier to delimit a pressure chamber therebetween, each of said pressure chambers being in fluid communication with a pressure feed line, each of said pressure chambers also being in fluid communication, through a throttle, with said respective at least one pocket;
- an interior space being enclosed by each of said plurality of hydrostatic support elements, each of said interior spaces being in fluid communication with an outlet line;
- and
- an adjustable throttle element being disposed in each of said respective outlet lines.
