TITLE WEB SUPPORTED MEMBRANE AND PROCESS AND APPARATUS THEREFOR ABSTRACT OF THE DISCLOSURE A process and apparatus for continuously forming a reinforced membrane of fluorinated polymers containing sulfonyl and/or carboxyl groups in melt- fabricable form and, after hydrolysis, the corresponding membrane in ion exchange form are disclosed. The membrane consists essentially of at least two layers of melt fabricable fluorinated polymer which contains side chain containing sulfonyl and/or carboxyl groups in melt fabricable form, and a woven reinforcing fabric comprising warp and fill strands. There is at least one layer of the fluorinated polymer on each side of the reinforcing fabric. The warp and fill strands of the reinforcing fabric define windows between the strands. Each layer of fluorinated polymer in at least 70% of the area in each of at least 90% of the windows being of uniform thickness within plus or Mooney 10%. The membrane has exceptional uniformity, and when used as the membrane which separates the compartments of a chloralkali cell, offers the advantages of low operating voltage, low power consumption and high current efficiency, and a long useful life without rupture.
