The drum (10) comprises a hub (11) defining in its central part a ring (11e) serving as the fixing point and position adjustment of the drum cylinder part (16) according to the length of the paper strip. The drum cylinder is made in two parts capable of separating from each other in order to define the drum circumference to meet the variations in format of the strip. The two parts are lockable in position. |
