VERFAHREN ZUM HERSTELLEN EINES ISOLIERMANTELS FUER EIN HEIZGERAET.

摘要

The outer, side cladding (1) is in the form of a cylinder whose upper and lower edges are turned over in an inward direction. The end covers (2,3) have a peripheral bead formed by folding or pressing. The bead is in the form of a reversed bend forming a peripheral groove into which the overturned edge of the cylindrical section (1) insulation is injected into the intermediate volume and the pressure it exerts locks the cladding sections together.
