    • A sealing element for a hydrostatically supported roll having bending control is disclosed in which a row of sealing elements is provided in a stationary crosshead for supporting a rotatable hollow cylinder arranged around the crosshead. Each of the sealing elements has a contact surface, including an enclosed circular rim, for abutting the inner circumference of the hollow cylinder. First ducts having a large cross sectional area are connected with a fluid supply line for supplying hydraulic fluid to a hydrostatic pressure chamber formed inside the rim. A cylinder volume is formed in the sealing element between the end of a longitudinal bore in the sealing element and a piston, which includes a central passageway connected with a second, separate fluid supply line. The piston is fixedly mounted to the crosshead and arranged in the cylinder volume. The cylinder volume is connected via second restricted ducts with respective rim chambers, which may be formed in the enclosed rim or radially outside same, for throttling fluid supplied to the rim chambers. The hydraulic fluid in the rim chambers forms a liquid film on the inner circumference on the hollow cylinder over which the sealing element uniformly abuts the inner circumference.
    • 公开了一种用于具有弯曲控制的静液压辊的密封元件,其中一排密封元件设置在固定十字头中,用于支撑围绕十字头布置的可旋转中空圆柱体。 每个密封元件具有接触表面,包括封闭的圆形边缘,用于邻接中空圆柱体的内圆周。 具有大横截面积的第一管道与用于将液压流体供应到形成在轮辋内的流体静力压力室的流体供应管线连接。 在密封元件中的密封元件中的纵向孔的端部和活塞之间形成有缸体,该活塞包括与第二单独的流体供应管线连接的中心通道。 活塞固定安装在十字头上,并被布置在汽缸容积中。 气缸容积通过第二限制管道与相应的轮辋室连接,其可以形成在封闭的轮辋中或径向外侧,用于节流供应到轮辋室的流体。 边缘室中的液压流体在中空圆筒上的内圆周上形成液膜,密封元件在其上均匀地邻接内圆周。

    • A roller is provided for a pressure treatment of a web of paper, textile, plastic film, and is composed of a rotary hollow cylinder which can be distinctly deformed under the effect of line forces in the roll nip. The roller includes a non-rotary cross-head which penetrates the rotary hollow cylinder over its length. On the side of the roll nip, hydraulic supporting elements are provided which can be pressed against the inside circumference of the hollow cylinder in the manner of piston/cylinder units. These supporting elements have a length of not more than 20 cm in the longitudinal direction of the cross-head, and are closely arranged next to one another in the longitudinal direction of the cross-head. The supporting elements can be driven independently of one another at least in several groups. A sealing strip is also provided which continues in one piece over several supporting elements. The supporting elements rest against the sealing strip from below, and the sealing strip acts against the inside circumference of the hollow cylinder, at the top. At the top, the sealing strip has a bearing pocket above each supporting element. The edges at the adjacent sides of bearing pockets which follow one another in the longitudinal direction of the roller are formed by a transverse edge common to both bearing pockets.

    • A wet press of a paper-making machine includes a pair of rolls defining a roll gap through which the paper to be treated and belt-shaped felt are simultaneously conducted. The felt is guided in a closed loop path by additional rolls which include a tightening roll. The tightening roll can be tilted to reduce roll vibrations by tightening the felt to set vibratory marks formed in the felt at an angle relative to the transverse width of the felt and the roll gap. A controllable positioning device is provided which includes a motor operated by a controller during predetermined time intervals or as a function of actual vibrations sensed at the pair of rolls forming the roll gap to automatically vary the tilt angle.
    • 造纸机的湿压机包括一对限定辊间隙的辊,待处理的纸和带状毡同时通过该辊间隙。 毛毯由包括紧固辊的附加辊在闭环路径中引导。 可以通过收紧毛毯来使紧固辊倾斜以减少滚动振动,以使毛毡中形成的振动标记相对于毛毯的横向宽度和辊间隙成一定角度。 提供了一种可控定位装置,其包括在预定时间间隔期间由控制器操作的电动机,或者作为在形成辊间隙的一对辊中感测到的实际振动的函数,以自动改变倾斜角度。
