Abstract
A process of forming a gasket with a minimal production of waste material is disclosed. A suitable fiber is mixed with a binder in water to form a fiber-binder aqueous mixture. The mixture is then deposited on a screen in a predetermined pattern to form a gasket preform with apertures in predetermined locations therein. The gasket preform is subsequently dewatered and cured. The gasket preform can be provided with differential thicknesses and preformed inserts to impart, respectively, selective control of the sealing capability of and reinforcement to the resulting gasket.
