Abstract
The invention concerns a method of welding a laminate for the production of flexible tubular plastic bodies. The method comprises the following operations: a laminate is shaped around a welding tool, the ends of the laminate to be welded are heated, the ends are pressed together and at least partly cooled, the welded zone is deformed so as to increase its area, and the weld zone is cooled. The invention also concerns a device that is suitable for using the method mentioned above.
