A sheet bending machine contains a bed and supporting rolls and a pressure roll installed on it, with a device for creating the bending force equipped with pressure sliders, which are bring to action by pressure and rotary hydraulic cylinders, and device for creating the effort of anti-bending of pressure roll, which contains piston hydraulic cylinders. The rotary hydraulic cylinders are also of piston type and their piston cavities through the hydraulic distributor are connected with the rod cavities of hydraulic cylinders of anti-bending, and the rod cavities of rotary hydraulic cylinders through hydraulic distributor are connected to the piston cavities of hydraulic cylinders of anti-bending.
