Abstract

A diaphragm made of rubber or rubber-like plastics materials with one or more textile reinforcing plies (3) has a flat base (6) which is supported against a rigid disc (9) and which is provided with one or more concentric ring grooves (11, 12) in the surface thereof facing the disc (9). The grooves provide manufacturing advantages, notably the prevention of creasing of the reinforcement during moulding. Additional grooves (13) may be provided in the transition zone (7). <IMAGE>
