摘要

Improvements in the construction of mass transfer devices, characterized in that to ensure a semi-permeable membrane, constructed of material that is difficult to adhere to, to a waterproof support, an adhesive member is applied on both sides along one side of the face. Said support; to the extension of said membrane on said tape, with a longitudinal edge of the first superimposed on the latter; the application of a strip of sealing material on the assembly of said belt and the said longitudinal edge of the membrane; and then folding the support and the membrane along transverse folding lines, to clamp and tighten said strip of sealing material between the folds of the membrane.
