Abstract
A method for embossing a separating membrane of a pressure transfer means including a membrane carrier having a membrane bed. With the method, an optimal forming of the separating membrane matched to the form of the membrane bed is achievable. The method includes steps of: welding a planar, separating membrane blank onto the membrane carrier; filling with a lubricant a pressure receiving chamber enclosed by the welded, separating membrane blank and the membrane carrier; producing the separating membrane from the separating membrane blank by embossing the separating membrane blank by pressing it against the membrane bed while lubricant is present in the pressure receiving chamber.
