Abstract:
A lamination machine for laminating two or more layers of material to each other through employment of a heat activated adhesion constituent, the machine comprising:a) upper and lower continuous opposing conveyor belts disposed one above the other to form a lamination passage therebetween having an entrance through which two layers of material can travel when placed on the lower conveyor belt for continued travel through the lamination passage to an exit;b) at least one pressure roller tensioned against the layers of material to be laminated, whereby said layers of material traveling in contact with said at least one pressure roller are adhered to each other to form a laminated product;c) a heating module disposed between the upper and lower conveyor belts between the entrance and the at least one pressure roller, said module comprising a plurality of substantially rigid respective heater components positioned immediately above and immediately below the upper and lower conveyor belts for melting said heat activated adhesion constituent disposed between said layers of fabric when said layers travel through the heating module, with each heater component comprising an elongate one-piece heat-conductive extrusion structure with a generally T-shape cross section wherein a substantially hollow channel is disposed vertically and a plurality of walled chambers in communication with respective heat sources are disposed horizontally; andd) a cooling module disposed between the upper and lower conveyor belts between said at least one pressure roller and the exit, said cooling module having a plurality of substantially rigid respective cooler components positioned immediately above and immediately below the upper and lower conveyor belts for cooling a laminated product subsequent to lamination thereof when said layers thereof travel through the cooling module, with each cooler component comprising an elongate one-piece heat-conductive extrusion structure with a generally T-shape cross section wherein a substantially hollow channel is disposed vertically and a plurality of walled chambers in communication with a cooling fluid are disposed horizontally.
