たまりを作る前のクラム１０が入れられる。[Example] FIG. 1 is a sectional view showing the configuration of a production device for producing a Mooni test piece based on the production method according to the present invention. In the production device 1, a press frame 6 to which a pressing rod 5 is attached is installed at the upper end of a support column 3.4 erected at the end of a pedestal 2. A press jack 7 operated by pressure oil is provided in the center of the pedestal 2. A mold 9 for producing a Mooney test piece is placed on a rod base 8 of a press jack 7. The opening of the mold 9 is large enough to fit the pressing rod 5, and the crumb 10 is placed in the mold 9 before being made into a rubber mass.

できる。In order to create a Mooney test piece using the manufacturing device configured as described above, first, the crumb 10 is placed in the mold 9, and the mold 9 is placed on the rod pedestal 8. In this state, when pressurized oil is injected from the boat B of the press jack 7 and the rod base 8 is pushed up, the formwork 9 also rises and the pressing rod 5 is inserted into the formwork 9, and the crumb 10 is compressed. be done. Since the inner surface of the formwork 9 is formed in the shape of a test piece of the Mooney tester, a rubber having the shape of the formwork 9 is created from the compressed crumb. Therefore, the rubber taken out from the formwork 9 after compression can be used as it is as a test piece for the Mooney tester.
このように上記実施例によれば、ゴムのかたまりを作る
前のクラムを直接試験片形状にプレスして試験片を作成
