System for joining sheets to form a belt

A system for joining a first sheet to a second sheet comprising:

• a first rigid plate;
• a thermal conductive layer consisting of a material selected from polyethylene terephthalate (PET), polyimide, or polycarbonate on the first rigid plate;
• positioning a first sheet having a polycarbonate layer and a polyurethane layer on the thermal conductive layer;
• wherein the polyurethane layer is adjacent to the thermal conductive layer;
• positioning a second sheet having a polycarbonate layer and a polyurethane layer on the thermal conductive layer;
• wherein the polyurethane layer is adjacent to the thermal conductive layer;
• wherein an edge of the of the first sheet abuts an edge of the second sheet;
• a second rigid plate of transparent material on top of the first and second sheet;
• a press for applying pressure to the first and second sheet;
• and laser welding the edge of the first sheet to the edge of the second sheet with a first laser.
