Abstract
Disclosed is an improved heated can roll for paper-making machines having a high thermal efficiency. The improvement is in a means for insulating the ends of the internally heated can rolls to provide segmental heat insulating part spaced from the roll end or head to provide an air space adjacent to the head or roll ends, resulting in a large reduction in heat loss through natural convection, convection due to rotation, forced convection due to air draft, and radiation and resulting in a more uniform drying surface temperature.
