PROCESS FOR PRODUCING METALLIC GASKET
Document Type and Number:
WIPO Patent Application WO/2007/010914
Kind Code:
A1
Abstract:
This invention provides a metallic gasket comprising a thin metal plate in a three-dimensional
form having an inclined surface and a seal part of a cured rubber layer provided,
on the surface of the bead part, astride the upper part and the lower part with the
inclined surface being located between the cured rubber layer provided in the
upper part and the cured layer provided in the lower part. In the production of
the metallic gasket, the seal part extended from the top of the bead part to a part
near the upper part of the inclined surface and the seal part extended from a part
near the lower part of the inclined surface to the flat part in the lower part are
connected to each other by a liquid rubber material spread from both seal parts
along the inclined surface, before drying and curing of the material for the formation
of both the seal parts. The liquid rubber material is preferably coated by screen
printing. The rubber part formed by silk screen printing can contribute to the
realization of even thickness after drying and curing.
