Procedure for the hermetic sealing of filter elements inside a framework essentially characterized by the fact that between the reinforcement and the filter material, and in contact therewith, a sheet of a thermoplastic material capable of softening with or without physical-chemical transformation, by the action of heat, and between this sheet and the reinforcement a sheet of a material susceptible to expansion at the softening temperature of the thermoplastic material, then the assembly is brought to this temperature, so that expansion of the expandable material compresses thermosensitive matter against the filtering matter, to wrap and close the edges of it.
