ABSTRACT:
A method of molding an elastomeric resilient ring member having a generally +-shape comprising the steps of providing a mold having a pair of mold halves, each having an exposed annular mold cavity therein, the surface defining each of the cavities comprising first and second inwardly directed lobes extending at a 90.degree. angle to each other from the inner corners of the cavity, at 45.degree. angles to the plane of the cavity; and using such a mold for molding, in a conventional manner, a resilient ring member.
