A calender roll comprises a substantially cylindrical roll body formed with a multiplicity of angularly equispaced axial heating passages proximal to a rolling periphery of the body, and a pair of recesses opening axially outwardly at opposite ends thereof, the recesses having bottom surfaces; and respective flange journal stubs formed with end faces defining respective gaps with the bottoms of the recesses. The gaps communicate with the axial passages and at least one of the stubs is provided with an axially extending bore communicating with at least one of the gaps for passing a heating medium through the axial passages. The heating medium is distributed to the axial passages by one of the gaps and is recovered from the axial passages by the other of the gaps. |
