Abstract

1380809 Corrugating sheets GMULLENDER 10 Feb 1972 [15 Feb 1971] 6365/72 Heading B5A [Also in Divisions F2 D1 and B3] Pipe bend insulating sheaths are formed from a flexible resiliently deformable sheet, e.g. of foamed plastics, which has been corrugated in longitudinal and transverse directions, e.g. by moulding or pressing, and which is subsequently cut along lines shown chain-dotted in Figs. 1a and lc into strips. The strips are then cut transversely, e.g. as at (73), (74) in Figs. 2a and 2b (not shown), to provide sections that can be folded inversely to wrap around a pipe bend. In Figs. 3 to 6 (not shown), the corrugations are formed with cusps (90) to (95).
