Abstract

A lightweight panel which can be used for acoustic insulation is made from wide stainless steel strip (11,12). Two coils of strip supply a press which forms rows of hemi-spherical depressions (14) in both sheets. Two other strips which are much narrower are formed into channel sections which form spacers (13) along the edges of the main strips. With these spacers in position the depressions (14) in the main strips are in contact with one another and are spot-welded together. The welded assembly is then cut transversely into panels.
