ABSTRACT:
The invention disclosed relates to a method of making laminated products such as furniture, cabinets, counters and the like. A laminate formed of thermosetting polyester saturated on paper of 8-12 mil thickness is bonded with a thermoplastic, thermoforming acrylic saturated on paper of 12-18 mil thickness. The bonded layers are shaped over at least two surfaces angularly positioned relative to each other. For examples, the bonded layers are shaped around sharp corners or edges of a substrate, such as conventional fiberboard, particle board or wood, under heat and pressure. A hot melt adhesive, preferably coated on the inner surface of the bonded laminate attaches the laminate to the one plane surface of the substrate and bending pressure is applied as the substrate and laminate pass through a series of rollers to bend the laminate in degrees around the corners and into contact with the other surface of the substrate. Pressures are in the 20-200 psi range and at temperature in the range of 350.degree.-450.degree. F. A superior product having a contiguous surface laminate on the substrate provides an element or elements for the manufactured article possessing heat and mar resistance.
