Abstract
The second corrugating roll of a machine for making single-faced corrugated board is formed from an inner core and a cylindrical sleeve having a number of spaced circumferential grooves. The sleeve may be made up from a number of axially abutted rings, the circumferential grooves being formed in the abutting faces of adjacent rings. Longitudinal passageways are provided in the outer peripheral surface of the core and radial apertures connect the passageways with the grooves, so that suction applied to one end of the passageways holds the material being corrugated in the corrugations of the roll. In a modified form the passageways are formed in the inner peripheral surface of the sleeve. The core is hollow and steam, or other heated fluid, passed through it to heat the roll.
