Abstract (en)

[origin: CA2612909A1] The invention concerns a device for cutting, in a web of continuously moving material, a variable longitudinal profile with predetermined and controlled random sequence, while being a simple, inexpensive and easy-to-use device capable of coping with high production rates. The inventive cutting device (5) comprises a pair of cutting tools (60) including two circular blades (61) co-operating with an anvil roll (71) arranged perpendicularly to the moving direction D of the web of material. Said cutting tools (60) are mounted mobile along two axes relative to a frame (50): one axis of rotation (A) perpendicular to the anvil roll (71) so as to modify the cutting angle of each cutting tool and one axis of translation (B) parallel to the anvil roll (71) so as to modify the space between the two cutting tools (60). Each cutting tool (60) is coupled to a rotational drive mechanism (8) and a translational drive mechanism (90) controlled in combination along the two axes (A, B) by a central control unit based on a cutting line with variable profile and with a predetermined random sequence. The invention is applicable to the manufacture of paper, fabric, plastic film and the like and in particular to mail processing machines.
