Web-reinforced separator and continuous method for producing same

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