Title:
RUBBER MEMBER STICKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2003/072475
Kind Code:
A1
Abstract:
A rubber member sticking device capable of preventing a held sheet material from being deformed and extended when the held sheet material is separated to suppress an energy loss and eliminate the traces of sucking holes, wherein, when an unvulcanized rubber sheet (12) is stuck, the unvulcanized rubber sheet (12) is supported by a separating surface (14) and fitting surfaces (19A) without providing a step between the separating surface (14A) of a flat plate (14) and the fitting surfaces (19A) of a lifting member (16), the unvulcanized rubber sheet (12) is fitted to the fitting surfaces (19A) of the lifting member (16), and when the unvulcanized rubber sheet (12) is separated, a hydraulic jack (20) lowers the lifting member (16) to provide a step between the separating surface (14A) of the flat plate (14) and the fitting surfaces (19A) of the lifting member (16) so as to support the unvulcanized rubber sheet (12) only by the separating surface (14A) of the flat plate (14), whereby since the unvulcanized rubber sheet (12) can be easily separated, the deformation and extension of the unvulcanized rubber sheet (12) at the time of separation can be suppressed.
