摘要： A calender arrangement includes end rolls that are in the form of deflection controlled rolls having an internal stroke. One of the end rolls comprises at least one stop element that is in the form of a hydraulic positioned hydrostatic element which, together with the internal wall of the roll sleeve, defines a gap. When a constant throughput of hydraulic medium is fed in, an equilibrium of forces is produced, at which equilibrium the roll sleeve is positioned. The pressure built up in the process is a measure of the positioning forces. Small departures from the target position are permitted without control intervention.

摘要： A roll with a revolving hollow cylinder which forms the working roll circumference, and a stationary crosshead penetrating said hollow cylinder lengthwise and leaving clearance all around to the inner circumference of the hollow cylinder in which the hollow cylinder can shift radially as a whole, e.g., can drop under its own weight on to the top side of the crosshead. A damping element is provided to damp this sinking movement before contact is made. It features a piston which plunges into a cylinder filled with hydraulic fluid and initially open to the top. During the plunging action, the hydraulic fluid is displaced out of the cylinder and flows away, in a throttled state, between the piston and the cylinder and/or through especially provided choke bores, so that the damping effect is attained.
