    摘要： A calender roll wherein the flexible shell is supported by a row of primary hydrostatic bearing elements serving to transmit first forces toward the nip of such roll with a second roll and wherein the shell is further acted upon by a row of secondary hydrostatic bearing elements which generate second forces opposing the first forces. The rate of fluid flow through the secondary bearing elements is regulated with a view to conform the temperature of the shell along the nip of the two rolls to a preselected pattern. To this end, the compensator of a computer in the fluid pressure regulating unit insures that pressure changes are distributed among the primary and secondary bearing elements with a view to match each change of the first forces by an equal change of the second forces. The temperature of the fluid is regulated only ahead of the regulating unit. The compensator cooperates with the secondary bearing elements to ensure that the temperature of the shell can be changed along the nip without altering the temperature of the fluid.

    摘要翻译： 砑光辊，其中柔性壳由一排初级静压轴承元件支撑，用于通过第二辊将第一力朝向该辊的辊隙传递，并且其中壳体进一步被一排次级静压轴承元件作用，所述第二静压轴承元件产生 反对第一力量的第二力量。 调节通过次级轴承元件的流体流速，以使外壳沿着两个辊的辊隙的温度符合预选图案。 为此，流体压力调节单元中的计算机的补偿器确保压力变化分布在主要和次要轴承元件之间，以便使第一力的每个变化与第二力的相等变化相匹配。 流体的温度仅在调节单元的前面调节。 补偿器与辅助轴承元件协作，以确保壳体的温度可以沿辊隙改变而不改变流体的温度。
