ABSTRACT:
An arrangement for a drying cylinder in a paper/board machine including a steam, condensate and/or water coupling. The coupling includes a steam pipe through which steam is passed into an interior of the drying cylinder, a condensate pipe through which condensate is removed from the interior of the drying cylinder, a unitary coupling frame arranged in connection with an end of the cylinder and including an exhaust connection coupled to the condensate pipe, an annular groove arranged in a face of the coupling frame facing toward the drying cylinder, and at least one spring socket opening into the annular groove, the arrangement also includes a revolving axle arranged at one end of the drying cylinder through which the steam and condensate pipes are passed, a bearing housing for rotatably supporting the axle, a piston arranged in the annular groove of the coupling frame, and at least one spring arranged in a respective spring socket of the coupling frame to press the piston against a portion of the axle. Each spring is arranged between the piston and a face of the respective spring socket. Fastening means are provided for fixing the coupling frame to the bearing housing.
