<p>A rotatable perforating roll, for use in a continuously operating paper-converting rewinder, comprises at least a first plurality of pockets and a second plurality of pockets, each of the pockets designed to receive at least one perforating surface therein. The pockets are spaced apart from one another along the roll's outer circumference such that the pockets of the first plurality are equally spaced from one another at a first angular distance, and the pockets of the second plurality are equally spaced from one another at a second angular distance different from said first angular distance, but the pockets of the first plurality are unequally spaced from the pockets of the second plurality.</p> |
