摘要

An apparatus for heating continuous materials in motion, consisting of a hollow rotary metal roller for heating the continuous material as it is brought into contact therewith, a stationary metallic core of high thermal capacity within said roller, a main part of which is the peripheral surface of said core very close to the inner peripheral surface of said roller, a means for heating said core and a liquid or solid thermally flowing conductors contained in the space comprised between the core and the inner face of the roller in a at least sufficient amount to fill said space on said main part of the peripheral surface of the core.
