Abstract

The present invention relates to a mould for producing membranes for autoclave vessels and the like of the type having symmetrical parts. It comprises at least one male component positioned between a pair of female half-components and optional retractable carriages that define at least one impression for the injection and/or casting of rubber or the like to form at least one membrane. The mould is characterised in that the impression extends axially from a generally frustoconical base portion to a spherical cap at the other end, forming across each section a multilobate figure. The patent also covers a membrane moulded in multilobate form that expands, greatly increasing its volume, during operation inside an autoclave vessel. <IMAGE>
