A rotatable perforating roll (1d), for use in a continuously operating paper-converting rewinder, comprises at least a first plurality of pockets (12a) and a second plurality of pockets (12b), each of the pockets designed to receive at least one perforating surface (20) therein. The pockets (12) are spaced apart from one another along the roll's outer circumference such that the pockets of the first plurality (12a) are equally spaced from one another at a first angular distance (A), and the pockets of the second plurality (12b) are equally spaced from one another at a second angular distance (B) different from said first angular distance, but the pockets of the first plurality (12a) are unequally spaced from the pockets of the second plurality (12b).
Ce rouleau de perforation rotatif (1d), utile dans un dispositif de rebobinage et de transformation de papier fonctionnant en continu, comprend au moins plusieurs premières (12a) et plusieurs secondes (12b) poches, chaque poche étant conçue pour recevoir au moins une surface de perforation (20). Ces poches (12) sont espacées les unes des autres le long de la circonférence extérieure du rouleau, de façon que les premières poches (12a) soient espacées de manière égale les unes des autres, formant entre elles une première distance angulaire (A), et que les secondes poches (12b) soient aussi espacées de manière égale les unes des autres, formant entre elles une seconde distance angulaire (B), différente de la première distance angulaire, toutefois, l'espacement entre les premières (12a) et les secondes (12b) poches étant inégal.
