ABSTRACT:
In the manufacture of insulating shells formed by a felt of mineral fibers wound around a mandrel, main pressing elements intervene as soon as the winding begins and remain in contact with the surface of the shell during the entire winding phase. Auxiliary pressing elements intervene only when the shell, during shaping, has reached a given outside diameter of, for example, 200 mm. The invention applies particularly to the insulation of conduits of small and average outside diameters.
