Abstract
A folding-pressing operation is carried out on the strip (17) in successive steps, by means of two opposed dies (11,12) with a relative movement alternating between coming together and moving apart, these dies having active surfaces (11,12) which are substantially conjugate with the two faces of the corrugation.

Method of manufacturing, from a strip of metal (17), a structured packing corrugation (1) having a rectilinear region and a non-rectilinear region, comprising performing a folding-pressing operation on a metal strip (17) in successive steps, by means of two opposed dies (11, 12) with a relative movement alternating between coming together and moving apart, these dies having convex apexes and active surfaces (11, 12) which mate with opposite faces of the corrugation, wherein, in at least said non-rectilinear region, said convex apexes (13A to 16A) of at least one die (11, 12) have a reduced height compared with that of said rectilinear region.
