Abstract
The internal ribs of the drying cylinders are formed with cross-sections which are of parabolic shape or substantially parabolic shape in order to obviate any additional thermal stressing of the cylinder. The rib cross-sections are each situated in a zone bounded outwardly by a hexagon which consists of a rectangle of full rib width and a height equal to 0.75 times the rib height and an adjoining trapezium having a width 0.65 times the maximum rib width at the top of the rib and inwardly by a pentagon of a width of 0.7 times the full width at mid-height of the rib and an apex at the maximum height of the rib.
