Abstract
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).

1-15. (canceled)
A machine (1) for continuous manufacture of tubular box bodies to be manufactured, the machine comprising:
- at least one longitudinal forming mandrel (3) whose cross-section corresponds to an internal cross-section of the tubular box bodies to be manufactured and around which at least one longitudinally unwound and previously at least partly glue-coated strip of material (2) is applied and folded in order to form a closed tubular profile (4),
- pressing means (20) arranged for rolling the at least one strip of material (2) against the forming mandrel (3), and
- traction means (10) arranged for moving continuously the tubular profile (4) along the forming mandrel (3),
- wherein the pressing means (20) and the traction means (10) are distinct and the pressing means (20) comprise a plurality of press rollers (21, 21′) mounted free in rotation about their axis, and the press rollers are deformable and radially distributed around the forming mandrel (3) so as to fit a periphery of the mandrel.
