    摘要: The present invention provides a raw rubber lapping film formed of an ethylene·&agr;-olefin random copolymer comprising ethylene unit and an &agr;-olefin unit having 4 to 20 carbon atoms and a raw rubber bale lapped with this film. Since the film is superior in strength and release properties and has good dispersibility in ethylene·&agr;-olefin copolymer rubber, the operation of lapping raw rubber with a film, the operation of stripping a film from a lapped raw rubber bale and the operation of separating each of a plurality of raw rubber bales are carried out easily and yet there is no adverse effect on the subsequent rubber processing step without stripping the film by heating at a temperature higher than the melting point of the film at the time of kneading.

    摘要: A spiral wound gasket having an annular body serving as a centering member which is integrally disposed at the inner periphery side of a gasket body formed by winding, in the form of a spiral. The gasket body comprises a metal hoop material and a filler material overlapping each other. When this gasket is disposed at fit-joint-type pipe connection portions of the exhaust pipe system in a motor vehicle, the annular body serves as a centering member to prevent the gasket body from protruding into the fit joint. This prevents the gasket body from deterioration and damage, thus assuring a high sealing property for a long period of time. Further, merely by inserting and fitting the gasket, the gasket may be automatically aligned and positioned with respect to the fit joint. Further, the inner peripheral surface of the gasket body and the annular body form an annular closed space, thus making the entire gasket into a lightweight design.
