ABSTRACT:
A drying cylinder adapted to receive steam therein includes a cylindrical cylinder jacket and two end covers. There is a flange connection between the jacket and the covers. The jacket has a rectangular cross-section flange. The covers have an L-shaped flange which receives the end flange of the cover. The covers are concave to the outside of the cylinder. The point of intersection of a curved line through the cover and of the axial center line of the axial arm of the cover flange lies at a distance from the outer face of the flange of the end cover that is at most about 60% of the axial length of the axial arm of that flange. There is thermal insulation on the axially exterior side of each cover.
