Abstract

A method for reconditioning of the sealing face (11) at the opening of the manhole (10) of a drying cylinder (K) of a paper machine when the cylinder (K) is in its operating position in the paper machine. In the method a separate frame part (13) is attached to the cylinder end. The frame part (13) comprises guides (15a, 15b), along which a machining unit (16) is displaced which is fitted to machine the sealing faces. Also disclosed is a device for use in the method.
