VERFAHREN UND GERÄT ZUR HERSTELLUNG EINES LINEAR UMHÜLLTEN, THERMISCH ISOLIERTEN ROHRES

摘要

The invention pertains to the apparatus and process for shaping and forming of thermal insulation materials around tubes and pipes in a continuous production process wherein the tube or pipe and a long singular strip of insulating material passes linear with the tube or pipe through a shaping die. The shaping die forms the insulating material around the circumference of the tube or pipe without substantial compression and is captured by overlapping coils of helical wound tape, wire or like material.
