ABSTRACT:
A process for preparing an ion-permeable web-reinforced separator membrane includes the steps of: providing a web (2A) and a suitable paste (5), guiding the web (2A) in a vertical position, equally coating both sides of the web with the paste to produce a paste coated web (2B), and applying a symmetrical surface pore formation step and a symmetrical coagulation step to the paste coated web to produce a web-reinforced separator membrane.
