Abstract
The roll comprises a core (6) and a sleeve (7) in which latter are provided ducts (8) for the circulation of a cooling fluid. According to the invention, the sleeve (7) is rigidly connected to the core (6) in its axially median part and substantially throughout its circumference by an assembly which prevents any axial and radial displacement in this median part of the sleeve relative to the core, such as a dovetail assembly (9, 10) or a T-way assembly. The sleeve is in contact with the core throughout its width and is maintained by its edges (7', 7') on the core by maintaining means (11, 12, 13, 14) which allow an axial displacement but prevent a radial displacement of the edges of the sleeve relative to the core.
