Abstract
A fabric reinforced molded conical diaphragm and method of making in which the parting line of the diaphragm mold is arranged such that the flashing and reinforcing fabric of the molded diaphragm are on the sidewall of the outer clamping bead at a location displaced from the juncture of the sidewall and the bottom surface thereof, so that upon inverting the diaphragm member, the fabric free bottom surface of the clamping bead is transposed to the sidewall of the diaphragm clamping bead, thereby providing a smooth, accurately sized outer periphery of the diaphragm to facilitate its assembly.
