Abstract

PURPOSE: To obtain an asbestos gasket, wherein the superposed surfaces at the ends are completely integrated, simply, by kneading asbestos with a binding rubber in the presence of a solvent, by volatilizing the solvent from a preformed article, and by hot-pressing the article.
CONSTITUTION: A kneaded material C of asbestos, a rubber as a binder, and a solvent, is fed from the hopper 11 of the extruder 1 and extruded through the die 12 into the soft rod R containing the solvent. The rod R is then packed into the groove 21a of the mold 2 for a gasket with ends r1 and r2 thereof superposed, and press molded at room temperature and 100W110kg/cm2 for 2sec to give a preformed article without boundary surfaces at the superposed ends r1 an r2. The article is then taken out by a knock-out pin mechanism, dried to volatilize the solvent, and hot-pressed, and if necessary vulcanized.
