Abstract

A roller is shown having an apparatus for cooling or heating the roller surface. The apparatus has essentially one or more chambers which are open relative to the roller surface. The chambers have a substantially square internal cross section. A fluid is fed in through the inlet ducts. During operation of the roller turbulence is formed in the chambers. The turbulence results in a longer retention time for the fluid in the chambers thus producing a greater cooling or heating effect for the amount of fluid fed in.
