Abstract
A heated roll for effecting heat treatment of materials has an outer cylindrical shell, an inner cylindrical shell spaced from the outer cylindrical shell, a wall defining an annular space between the shells, partitions in the annular space for forming flow channels for the heating medium passing through the inner space, feed means for introducing a heating medium into the annular space and a discharge means for discharging the heating medium from the annular space and from the roll. The discharge means includes a centrally located backflow conduit and defines a single stationary discharge opening arranged in the roll below the roll axis for discharging heating medium selectively from the lower portion of the roll to the centrally located backflow conduit.
