发明名称 VERFAHREN ZUR HERSTELLUNG VON ROHREN DURCH SCHWEISSEN
摘要 The method involves arranging a laminate (2) around a welding rod (6), and heating ends of the laminate, which are to be welded. The ends of the laminate are partially pressurized and cooled at the level of a welded zone (3), where the zone is deformed. The welded zone is cooled without attaining an ambient temperature between pressurization of the ends and deformation of the welded zone. The laminate is tempered at a temperature between 50 and 95 degree Celsius, during deformation of the welded zone. An independent claim is also included for a device for manufacturing flexible plastic tubular body.
