Abstract

The invention relates to a laser system for producing windows (20) in security paper (10, 10'), comprising: means (140, 150, 151) for guiding and transporting the security paper (10, 10') along a path inside the laser system; laser cutting means located along the path of the security paper (10, 10'); and suction means comprising at least one suction mouth (180) located along the path of the security paper (10, 10'). The laser system also comprises: laser control means configured such that the laser cutting means produce the window (20) in the security paper (10, 10') by means of continuous cutting using a pre-established template and a pre-established cutting zone. According to the invention, the suction means are located under the security paper (10, 10') below the cutting zone in order to suck up the window panel after it has been cut out of the security paper by the laser cutting means.

Abstract

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.
