A manufacturing machine in which the pressing mechanism (20), for rolling the strips of material (2) against the forming mandrel (3), and the traction mechanism (10), for moving the shaped strips of material along the forming mandrel (3), are distinct in order to separate these two functions. The pressing mechanism (20) comprises a plurality of deformable press rollers (21) mounted free in rotation about their axis and distributed radially around the forming mandrel (3) so as to fit the periphery of the mandrel. The traction mechanism (10) comprised several traction belts (11) carried by drive rollers (12) positioned downstream of the pressing mechanism (20). |
