Abstract

The invention relates to a machine for rolling and calibrating annular profiles meant to be used for rolling and calibrating annular profiles of flat iron or sectional steel and for bulging cones used in the machine building industry, and is an improvement of the main invention RO 111553. According to the invention, the machine comprises a hydraulic cylinder (33) actuating another hydraulic cylinder (32' or 32'' or 32''') in order to achieve either a pressure increment about two directions, or a pressure increment about one direction only, or no pressure increment at all.
