The ply overlap arrangement of the present invention comprises alternating the orientation or overlap direction of each ply of fabric strips with respect to a section of the peripheral reinforcing member so that each successive overlap end of strip is wrapped in the opposite direction from and falls on the opposite side of the reinforcing member from the preceding ply overlap end. Each overlap end is of sufficient length to extend back toward the center of the primary load carrying portion of the strips of the preceding ply. This arrangement, by extending the overlap ends back over the preceding ply of primary load carrying strips, ensures not only that an overlap of a strip will never be bonded to another ply overlap, but that each overlap will be bonded over a large area on one or both sides to a preceding ply of primary load carrying strips extending across the face of the closure or diaphragm.
