Abstract
A method and apparatus for producing continuous belts is disclosed. The belts are formed from plastic films and are used as transfer belts in electrographic printers and copiers. The ends of the film are welded together by abutting their front faces and the ends are held together under pressure while being heated by radiation to a temperature to cause welding of the ends.
