Hot wedge rotary heat sealing is a welding process using very precise heat, speed and pressure to join thermoplastic industrial fabrics and films.

During the hot wedge welding or seaming process, a heated wedge is precisely positioned at the weld point to provide the required heat. The fabric or film is then pulled across the heated wedge. Tightly controlled temperature of the wedge can range from 700F to 920F (400C to 490C), producing a perfect weld.
