Abstract
A two stage panel suitable as a bowling lane comprising a decorative laminate sheet bonded in situ to a substrate selected from the group consisting of natural wood, consolidated wood fibers, plywood, flakeboard, chipboard and hardwood. The plastic laminate sheet comprises a plurality of thermosetting resin impregnated core sheets, a melamine resin impregnated decorative fibrous print sheet and an overlying melamine resin containing protective layer. The surface of the bowling lane so produced is characterized by a falling ball impact resistance of at least 60 inches, a coefficient of friction of at least about 0.16 and a Taber abrasion resistance at least about 500 cycles.
Claims7
A bowling lane having a surface characterized by a falling ball impact resistance of at least 60 inches, a co-efficient of friction of at least 0.16 and a Taber abrasion resistance of at least about 500 cycles, said bowling lane comprised of at least one decorative plastic laminate which has been adhered to a substrate under conditions of heat and pressure, said laminate comprised of at least one thermosetting resin impregnated fibrous sheet underlying a melamine impregnated decorative fibrous print sheet and an overlying melamine resin containing protective layer, said substrate comprised of a cellulosic board of at least 60 pounds selected from the group consisting of natural wood, consolidated wood fibers, plywood, flakewood, chipboard and hardboard.
A method of producing a bowling lane having a surface characterized by a falling ball impact resistance of at least 60 inches, a coefficient of friction of about 0.16 and a Taber abrasion resistance of at least 500 cycles comprising:
- providing a substrate comprised of a cellulosic board of at least 60 pounds, said board selected from the group consisting of natural wood, consolidated wood fibers, plywood, flakeboard, chipboard and hardwood superimposing at least one thermosetting resin impregnated fibrous sheet over said substrate board in registration therewith;
- superimposing at least one thermosetting resin impregnated decorative fibrous print sheet over and in registration with said at least one thermosetting resin impregnated print sheet;
- superimposing at least one overlying thermosetting resin containing protective layer over said thermosetting resin impregnated decorative fibrous print sheet in registration therewith;
- consolidating said substrate, at least one thermosetting resin impregnated fibrous sheet, at least one thermosetting resin impregnated decorative fibrous print sheet and at least one resin containing protective layers under heat and pressure to produce a unitary decorative plastic laminate panel.
