Abstract
A method for manufacturing gasket material where a metal plate is coated with a compound that includes a compressible inorganic fiber, other than asbestos, a compressible organic fiber, and rubber and an inorganic filler. In forming the gasket material, the metal plate is coated with a heat resistant adhesive. The metal plate is then inserted between first and second metal rollers that are arranged adjacent and parallel to each other, rotate at different circumferential speeds to one another and in opposite directions, and heat resistant adhesive layer applied over the metal plate is opposed by the first roller. In which rolling, the compound with a solvent mixed therein is supplied to between the metal plate and the first roller that is turned at a circumferential speed that is slower than that of the second roller. The difference in the circumferential speeds of the first and second rollers provide for rubbing the compound over the entire metal plate surface, so as to uniformly coat the metal plate with the compound.
