Abstract
768,118. Corrugating. SOC. ANON. DES FORGES ET ACIERIES DE DILLING. Jan. 20, 1955 [March 16, 1954], No. 1729/55. Class 83 (4). A corrugated metal sheet is made by introducing a flat sheet 12 over its whole width between channelled cylinders 10, 11, which effect the formation of the corrugations in the sheet by drawing of the metal in a single operation. Following channelled cylinders 19, 20 may be provided to act as guiding means and to smooth the curves in the corrugations. The corrugated sheet has the same width as the flat sheet,
