摘要： Deflection controlled roll that includes a rotatable roll jacket, a rotationally fixed carrier arranged within the roll jacket, and a hydraulic support element arrangement positioned between the carrier and the roll jacket. A closed bearing ring is located in an end region of the roll jacket and is movable relative to the carrier in a press plane, and a bearing arrangement is positioned between the bearing ring and the roll jacket. The bearing arrangement includes at least two hydrostatic support elements which are mutually spaced in a peripheral direction and at least one of the at least two hydrostatic support elements is movable relative to the carrier. At least one force generating device is positioned between the carrier and the roll jacket and is arranged to act generally radially in the press plane. The at least one force generating device is located to radially penetrate the bearing ring.

摘要： A calender for the treatment of a paper web has at least one roller stack made of "hard" and "soft" rollers. The soft rollers have a covering made of a plastic whose recovery, after deformation, is such that the depth of the remaining deformation, after a faulty formation of up to 1 mm thick passes through the working nip is a maximum of 5 percent of the thickness of the faulty formation. In this way, paper characteristics that have previously been obtained using conventional 12-roller calender can be obtained with a lower number of rollers.

摘要： A calender for treating both sides of a web of paper includes a roller stack. A working nip is formed between the juncture of one hard roller and one soft roller. A changeover nip is formed between the juncture of two soft rollers. The roller stack has eight rollers. The two middle rollers form the changeover nip. One of the middle rollers is a deflection adjustment roller and has an upper support device which can be pressure loaded and a lower support device which also can be pressure loaded. The supporting force that is exerted on the jacket by the upper support device is greater than the supporting force that is exerted by the lower support device.

摘要翻译： 用于处理纸幅两侧的压延机包括辊子叠层。 在一个硬辊和一个软辊的接合处之间形成工作辊隙。 在两个软辊的接合处之间形成转换辊隙。 辊子堆叠有八个辊子。 两个中间辊形成切换压区。 中间辊中的一个是偏转调节辊，并且具有可以被加压的上支撑装置和也可以被加压的下支撑装置。 由上支撑装置施加在护套上的支撑力大于由下支撑装置施加的支撑力。
