Abstract
An arrangement for manufacturing or treating a web material comprises a rotary hollow roll having a hollow jacket which has an axis, a central region around which a web material moves, and two axial end regions which are free from the web material, two bearing pins each supporting said jacket in a respective one of said end regions, at least one of which bearing pins has a passage for a heat-carrying fluid, a displacing member located inside the jacket and extending concentrically to and over the greater part of the jacket so as to form an annular gap between the displacing member and the jacket and communicating with the passage for heat-carrying fluid to supply the latter, and a heat-insulating element arranged at an inner side of each of the end regions of the jacket for reducing heat transfer from the heat-carrying fluid to the jacket.
