摘要: The invention relates to a method of producing a winding (1), e.g. for an electrical transformer, from a cylindrical, tubular metal element having a straight polygonal section. The inventive method is characterised in that it comprises the following steps consisting in: machining a series of essentially-parallel cuts through all of the sides (1a, 1c, 1d) of the tubular element excluding one last side (1b), said step being performed in a first series of passes; and, in a second series of passes, machining cuts in the aforementioned last side (1b) in order to form a junction with the cuts in the adjoining sides, such that said cuts are continuous and form a single helicoidal groove.

摘要: The invention concerns a structural profiled section, in particular for partitions. Said profiled section is characterised in that its cross-section comprises two parallel U-shaped parts, designed to receive the partition (14) panels, and the inner branches of the U-shaped parts are assembled by a transverse junction element (5) arranged at short distance from their respective bases (3c).
