A method of cutting an elongated multi-ply flat surfaced ribbon of web material (19) which includes advancing the ribbon along a linear path while rotating a pair of cantilever-mounted drums (29, 29') on opposite sides of the path to flank the ribbon flat surfaces, the drums each having a plurality of axially extending slots in the periphery thereof. A saw blade (23) is adjacent the path and orbits through the path so as to have the blade orbit intersect the drum slot orbits to transversely cut the ribbon while the saw is advancing parallel to the linear path.
Ce procédé, qui sert à couper un ruban de matériau en bande (19) à surface plate multicouche et allongé, consiste à faire avancer le ruban le long d'un trajet linéaire tout en faisant tourner en rotation une paire de rouleaux montés en porte à faux (29, 29') de part et d'autre du trajet linéaire, pour établir un contact au flanc avec les surfaces planes du ruban, les rouleaux conportant chacun plusieurs fentes s'étendant axialement à leur périphérie. Une lame de scie (23) est disposée adjacente au trajet linéaire et effectue un mouvement orbital le long de ce trajet linéaire, pour que son orbite vienne en intersection avec l'orbite des fentes des rouleaux, de façon à couper transversalement le ruban, pendant que le scie avance parallèlement au trajet linéaire.
