Heatable and/or coolable cylinder

摘要

Cylinder that includes at least one stationary portion and at least one rotatable portion and a support and a method for sealing the same. The at least one rotatable portion includes a bearing axle rotatably coupled to the support, and the at least one stationary portion includes at least one stationary connection that is rotatably coupled to the bearing axle and that is adapted for at least one of inserting and removing at least one of a heating and cooling medium through the bearing axle. The cylinder also includes a sealing device that is composed of at least one brush seal and that is positioned between the at least one stationary portion and the at least one rotatable portion. The method includes rotatably coupling a bearing axle of a rotatable cylinder to a support. The bearing axle is fixedly coupled to a rotatable member and includes a channel adapted for at least one of insertion and removal of at least one of a heating and a cooling medium through the bearing axle. The method also includes coupling at least one stationary connection to the bearing axle for relative rotation, and positioning at least one brush seal between the at least one stationary connection and the rotatable member.
