摘要

Improvements in the construction of cylinders or rollers for pressing-treating articles in the form of a band, for example for satining and printing paper and other materials, for squeezing liquid from textile articles, for calendering, for stretching sheets of artificial or rubber substance and other similar operations, as well as for pressing operations and for the rolling of materials to a certain thickness, which consists of a hollow body intended to rotate and forming the periphery of the roller and a fixed rigid core existing therein and intended to receive the load, characterized in that the hollow body forming the periphery of the roller is provided floating or suspended around the core and in the intermediate space (4) existing between the periphery of the core and the inner periphery of the hollow body (1) is it provides, on the side returned to the actuation point (5) of the roller, a pressurized liquid (6) or a gasiform medium that exerts pressure, providing a in isolation (7) with respect to the part of the intermediate space located by the side turned against the point of action of the roller.
