Abstract

A lamination machine for adhesively heat laminating adjacent surfaces of two or more layers of material to each other. The machine includes upper and lower opposing conveyor belts disposed one above the other to form a lamination passage therebetween and through which layers of material travel during lamination. At least one pressure roller is tensioned against the layers to be laminated. A heating module is disposed between the entrance and pressure roller, while a cooling module is disposed between the pressure roller and an exit. The heating module provides a plurality of rigidly maintained single-structure extruded heater components for melting an adhesion constituent disposed between the layers of material in preparation for lamination. Once the layers are pressured together to form a laminated product, that laminated product immediately enters the cooling module bearing a plurality of rigidly maintained single-structure extruded cooler components for cooling the laminated product as it travels through the cooling module. Rigidity of both the heater and cooler components can be enhanced by mounting hollow channels of both on respective rigid tubes. In this manner, a beneficial generally non-elastic lamination pathway is maintained for uniform production of laminated goods.
