Abstract (en)
[origin: GB2249274A] A method and apparatus for bending profiled sheet metal transversely to the longitudinal ridges and troughs of the profile is disclosed. This includes clamping the sheet between first and second longitudinally spaced and pivotable clamps (3, 4), pivoting the first clamp (3) to cause the sheet to deform around a die (11) provided on the first clamp whilst at the same time imparting a tensile load to the sheet via the second clamp (4). The tensile load is preferably kept at a constant value, and the second clamp (4) is free to pivot about an axis under the influence of the bending sheet.
