Abstract (en)

The method comprises carrying out a folding and swaging a sheet metal band in successive steps by means of opposite guides with an alternate bringing together and separating movement. The resulting wave (1) has two parallel lateral edges (2,3). Each edge forms a repetitive zigzag profile (4) with rectilinear sides (5) and upper (6) and lower (7) crest with as small a radius as possible. An Independent claim is included for a device for implementing the method.

Abstract (fr)

Suivant ce procédé, on effectue un pliage-emboutissage de la bande (17) par pas successifs, au moyen de deux réglettes opposées (11, 12) à mouvement relatif alternatif de rapprochement-éloignement, ces réglettes possédant des surfaces actives (11, 12) sensiblement conjuguées des deux faces de l'onde. Application aux colonnes de distillation d'air. <IMAGE>
