    摘要: The end portions of a rotary shell forming part of a calendar roll can be heated or cooled by a suitable (gaseous or hydraulic) fluid which is admitted into axially parallel first channels of the shell. Such channels can extend from end face to end face of the shell or only in the region of one end face each. The first channels receive the fluid from second channels which extend radially inwardly to the internal surface of the shell, and spent fluid is admitted into third channels which extend from the respective first channels to the internal surface of the shell. The first channels accommodate axially adjustable throttles which are used to regulate the rate of fluid flow in the shell and to thus regulate the temperature of the respective end portions of the shell.
