PCT No. PCT/EP90/01130 Sec. 371 Date Jan. 10, 1992 Sec. 102(e) Date Jan. 10, 1992 PCT Filed Jul. 11, 1990 PCT Pub. No. WO91/00800 PCT Pub. Date Jan. 24, 1991.A process for producing a layered material in sheet or membrane form from thermoplastic foam is described. The laminated material is suitable in particular for use as a drainage sheet or membrane. To produce the membrane, the thermoplastic foam in the form of strips, lengths, shreds or the like is piled up to form a layer of uniform height and compressed and compacted at a temperature below the softening temperature of the foam. Subsequently, the compressed and compacted layer of thermoplastic foam is perforated and fused with the aid of pins which are heated to a temperature of 400 DEG to 800 DEG C., whereupon the perforated and fused layer is cooled while maintaining the compression. |
