Abstract
A gasket manufacturing method is provided. The gasket has a base material with a bead and an elastomeric gasket body disposed in a top portion of the bead. The method includes sequentially forming the bead on one part of a plane of the base material and applying a molding material of the gasket body to the top of the bead. When forming the bead on the one part of the plane, a protrusion is formed in each end in the width direction in the top of the bead. The protrusions are utilized as a coating width defining means of the molding material when applying the molding material to the top of the bead.
