ABSTRACT:
A deep drawn, synthetic-foil-sealed textile with foamed backing is perforated by applying hot pressurized air towards the foil, locally and in discrete spots, so that the foil melts locally, and foil material is blown into the textile under formation of a perforation duct that is bonded to the textile material underneath.
