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.

The invention relates to a suspended ceiling comprising at least one canvas (4) which is tightened at the periphery thereof to support elements (1) that are fixed to the ceiling and/or walls of a room. The inventive suspended ceiling is characterized by the fact that it also comprises ceiling tiles (5) which are held by the support elements with the aid of holding means that allow the tiles (5) to be dismounted without first having to fully or partially dismount the canvas (4).

The invention concerns a false wall formed by a matrix of caissons (20, 22, 22') each consisting of a frame whereon a fabric (12) is stretched. Said false wall is characterised in that each of the sides (23) of the frame consists of a rigid masked rail element, and it comprises means (32, 33) capable of associating in parallel, with a given spacing (e), two adjacent sides (23) of two neighbouring caissons (20, 22, 22').
