摘要： A method including the following steps: placing a rear locking collar (62) around an outer ply (25), placing a first shaping guide (82) for shaping the folding of the end segments (32) of the outer ply (25); folding the end segments (32) of the outer ply (25) rearwards, folding the end segments (32) of an inner ply (24) rearwards. Before the step for folding the end segments (32) of the inner ply (24) rearwards, a second shaping guide (84) is placed for shaping the folding of the end segments (32) of the inner ply (24), a second shaping guide (84) being separate from the first shaping guide (82), the end segments (32) of the inner ply (24) bearing on the second shaping guide (84) after the folding step.
