Laminate composite wall coverings and method for making such
First Claim
1. A method for forming a laminate composite wall covering, said method comprising the steps of:
- applying an adhesive to an application zone located on an inner surface of said extrudate, said adhesive applied so as to substantially cover said application zone;
applying an adhesive to an application zone located on an inner surface of a backing layer;
said adhesive applied so as to substantially cover said application zone and placing the adhesive coated surface of said extrudate in contact with the adhesive coated surface of said backing layer and applying pressure, thereby forming a laminate;
wherein substantially immediate adhesion will occur, said adhesion of sufficient strength to allow transport of said laminate.

Abstract
The present invention includes a method for forming laminate composite wall coverings that minimize or eliminate failure causing voids, and laminate composite wall coverings formed thereby. One side of an extrudate preferably has an application zone which is substantially coated with an adhesive. A second material, referred to as a backing layer, is also preferably coated substantially or completely on one side with an adhesive. The coated surfaces of each of the extrudate and backing layer are then brought together under pressure to form a laminate composite wall covering. Preferably, the adhesive selected provides substantially instantaneous adhesion between the extrudate and the backing layer so that the laminate composite wall covering may be handled virtually immediately after joining of the components. The surfaces may include a predetermined curvature.
