<p>Process for embedding, in an impermeable manner, one or more membranes in a thermoplastic material, which simultaneously forms the sealing surface between at least two chambers of a module subdivided by the membranes, characterised in that at least one of the flat structures forming the module consists of thermoplastic material, and at least one of the flat structures consisting of thermoplastics material projects beyond the plane of the sealing surface, that with the aid of a mould flange, the surface temperature of which exceeds the melting temperature of the thermoplastic material, the projecting parts are melted, and the mould flange is moved towards the sealing surface so that a part of the thermoplastic material penetrates as melt into the intermediate spaces and the other part is moulded as a sealing surface, after which the melt is made to set. …<??>Even tubular membranes can be embedded by this process. …<IMAGE>… </p> |
