Abstract
A process and device for producing a flexible layered article suitable for use in water proof garments wherein one of said layers is a microporous membrane material produced from the 'solvent non-solvent' method wherein a fabric backing coated with the membrane material dissolved in a solvent is contacted with a drum having gripping means offering substantial resistance to the natural tendency of the coated fabric to curl when immersed in a non-solvent for the polymer material.
