PROBLEM TO BE SOLVED: To provide a vulcanization press apparatus for an endless belt capable of certainly make respective outer molds synchronous. SOLUTION: When an endless belt A is pressed by respective outer molds 1, operation oil is supplied to respective hydraulic cylinders 3 by a plurality of auxiliary pumps 7 integrally rotated each other to always uniformize the flow rates of the operation oil flowing into the respective hydraulic cylinders 3. At this time, even if irregularity is generated in the load of the respective hydraulic cylinders 3, the pressures in the passages of respective hydraulic cylinders 7a become uniform by the pressure control circuits of the pressure control circuits 7. Since an operation oil flow rate control circuit 8 is provided in a part of the hydraulic cylinders 3 to which the outer molds 1 are downwardly attached, the outer molds 1 do not suddenly fall even when the wt. load of the outer molds 1 is applied to the hydraulic cylinders 3. |
