Abstract:
A laminate thermoplastic sheet, and an apparatus and a method of making the sheet are disclosed. The laminate sheet has a substrate layer, a middle foam layer, and a cap layer bonded together. Each layer is chemically compatible with the others, thereby facilitating a recycling thereof. The apparatus and the method of producing the sheet includes extruding the cap layer, feeding a sheet foam material for the middle layer in substantial alignment with the cap layer; providing a roll assembly that compresses the cap layer and the middle layer together and forms a bond therebetween; extruding a thermoplastic substrate layer; and compressing the laminate and the substrate layer to form a bond therebetween and form a final three-layer laminate sheet.
