Abstract: In a method for laminating a plastic web onto a plastic substrate, the web is moved past an adhesive coating station where one surface is coated with a mixture made of solvent and resin particles. The substrate is moved past a cleaning station, where a surface is also coated with a mixture made of solvent and resin. After the web and substrate pass through drying chambers, the coated surfaces are pressed together with rollers and heat is applied. The method is particularly suitable for laminating strips bearing a woodgrain pattern onto extruded thermoplastic members which are thereafter cut into segments for use in making prefabricated window systems.
