1955-54a ABSTRACT A rotary pressure applying roll which defines with a parallel complementary roll a nip for a running web of paper, textile or other flexible sheet material in a calender or the like has a cylindrical shell surrounding a stationary carrier in the form of a rigid shaft. A bearing element is installed between the shell and the carrier and several hydraulic pressure generating devices are mounted between the carrier and the bearing element to urge the latter against the internal surface of the shell. The pressure generating devices are spaced apart from each other, as considered in the circumferential direction of the shell, and the cylinder chamber of each such device can receive pressurized hydraulic fluid at a different pressure, The axis of a main pressure generating device is normally located in the common plane of the axes of the shell and of the complementary roll, The other device or devices are installed at the one and/or the other side of such plane and can be operated to counteract forces acting substantially tangentially of the shell. The carrier and the bearing element have cooperating spherical, flat and/or cylindrical guide faces which enable the bearing element to pivot about an axis that is parallel to the axis of the shell. - 1 -
