PROBLEM TO BE SOLVED: To provide a method for manufacturing a laminate rubber for a seismic isolation apparatus for raising a production efficiency per vulcanizing press. SOLUTION: The method for manufacturing a laminate rubber comprises the steps of preheating a hard metal plate 10 and crude rubber plate 11 to 40 to 60 deg.C, alternately charging the plates 10 and 11 preheated in the first step in a mold 9, then preheating the mold 9 to a temperature so that its interior is higher than the preheating temperature of the first step and the plate 11 is not progressively vulcanized, and pressurizing and heating it by using a vulcanizing press. Thus, the plate 11 is vulcanized, and the metal plate 10 and rubber material of the crude rubber plate 11 are vulcanized and adhered. |
