Abstract
Process for laminating. A macroapertured thermoplastic web is brought continuously into contact with the hot moving surface of a rotating roll. A fabric is pressed against the thermoplastic material on the roll and, within about five seconds, the fabric carrying the hot thermoplastic material is continuously peeled off the roll. The resulting fabric, carrying hot thermoplastic material, is then brought into contact with a preformed cellular layer.
