Rubber member sticking device










Image Number 12 for United States Patent #7578897.

Provided is a rubber member sticking device which prevents a sheet material held from becoming deformed and stretching during a separation operation, thus suppressing loss of energy and eliminating traces of vacuum holes. When an unvulcanized rubber sheet 12 is stuck, the unvulcanized rubber sheet 12 is supported by a separating surface 14A of a flat plate 14 and fitting surfaces 19A of a lifting member 16 without a difference in level being created therebetween. In this state, the unvulcanized rubber sheet 12 is in close contact with the fitting surfaces 19A of the lifting member 16. When the unvulcanized rubber sheet 12 is separated, a hydraulic jack 20 lowers the lifting member 16 to create a difference in level between the separating surface 14A of the flat plate 14 and the fitting surfaces 19A of the lifting member 16 so that the unvulcanized rubber sheet 12 is supported only by the separating surface 14A of the flat plate 14. Thus, the unvulcanized rubber sheet 12 can be easily separated, and deformation and stretching of the unvulcanized rubber sheet 12 during a separation operation can thereby be suppressed.
