<p>Device for the transverse cutting of cellulose-pulp bands that comprises a first transverse-cut rotating roller (1) with at least a first cutter (2) and a second transverse-cut rotating roller (3) with at least one fixed cutter (4a) and at least one retractable cutter (4b); the cutters (2, 4a, 4b) being arranged in respective positions such that in the cutting position thereof they coincide, upon rotation of the rollers (1, 3) on a transverse-cut line perpendicular to the direction of forward movement of a cellulose-pulp band (5) moving between the rollers (1, 2); a retraction mechanism (6) that allows the retractable cutter (4b) to be moved between a cutting position, in which the retractable cutter projects radially from the outer surface of the second roller (3) as far as a cutting line, and a retracted position, in which the retractable cutter (4b) is radially retracted from said cutting line.</p> |
