Abstract
A gasket having multiple regions of different densities and thicknesses is disclosed. First and second laminae of a gasket material are disposed in partial overlapping relationship. A perforated core is provided with a plurality of prongs. The prongs extend from a first side of the core into the first and second laminae so as to form a unitary gasket having a uniform thickness portion. The uniform thickness portion includes a first density region defined by that portion of the first lamina which was overlapped by the second lamina and a second density region defined by that portion of the first lamina which was not overlapped by the second lamina. Third and fourth laminae may also be disposed in partial overlapping relationship such that a plurality of prongs extend from a second side of said core therein so as to form the unitary gasket.
