摘要

Actuation device and hydraulic mantle for obtaining regulation and proper distribution of pressures on the rollers of the calenders comprising two independent cylinders with respective pistons through which act on respective levers with which pressure is exerted on the two ends of the rollers acting a lever on the ends of one side and the other on the other side; anchoring members of said levers for maintaining while the "separated rolls" position is of interest, whose organs -one for each side as well- are in turn driven by piston-tight struts fixed in cylinders and forced by opposing springs; a driving pump with its corresponding return tank and liquid intake; a set of pipes through which communication is established between the various parts and with the driving pump of the engine fluid and the appropriate valves by means of which the circulation distribution of the engine fluid is regulated in accordance with the maneuvers to be carried out and pressures that are interesting to have at each point in each moment which are suitable for corresponding manometers.
