Beschreibung
Zusammenfassung:	An equipment (1) including an axial-symmetrically shaped forming tool (5), rotating about a first axis and cooperating with an axial-symmetrically shaped mandrel (10) revolving about a second axis parallel to the first and having a predetermined longitudinal profile; and respective receiving rolls (14,15) carried revolving by a support adapted to support a perpendicular thrust (S) exerted in use on the forming tool, cooperating with a first and a second radial shoulder surface (17,18) of the mandrel between which the working surface (11) is delimited; the first and the second shoulder surface (17,18) of the mandrel have, at opposite ends (21,22) of the longitudinal profile of the working surface, a first and a second diameter (D1,D2), the first smaller than the second, the first shoulder surface (17) being arranged immediately adjacent to a first end (20) of the mandrel.
