Abstract

1,141,143. Laminates. BUKFLEX PROCESSES Ltd. 27 Jan., 1966 [28 Jan., 1965], No. 3776/65. Heading B5N. [Also in Division B2] A method of making laminated flexible sheet material comprises bringing together a preformed isocyanate-modified polyester film of a predetermined thickness and a flexible foamed polyurethane material lamina of a predetermined thickness and cellular structure, allowing the laminae to rest for a curing period and then applying a further isocyanate-modified polyester film to the first film to become cured and cross-linked in situ. The first film may be formed on a receiving surface from a solution, the cellular polyurethane film laid thereon, the resultant assembly being removed from the surface, preferably placed under tension and the second film applied. A backing sheet may be applied to the rear surface of the cellular sheet. At least one of the films may include a fibrous reinforcement. The product may be embossed prior to or after the application of any film.
