<p>The invention concerns a device for cutting, from a width of continuously conveyed material, a variable longitudinal profile in a controlled, irregular sequence, which nevertheless remains a simple, economical, easily implemented and configured device responsive to high speed production requirements. The cutting device has a pair of cutting tools cooperating with an elongate counter-cylinder extending perpendicular to the direction the width of material is conveyed. The cutting tools are movable along two axes from the frame: a rotational axis, perpendicular to the counter-cylinder so as to modify the cutting angle of each cutting tool, and a translational axis parallel to the counter-cylinder so as to modify the distance between the cutting tools. Each cutting tool is connected with a rotational and a translational drive mechanism which are controlled by a central processing unit according to a cutting line with a variable profile and in a given irregular sequence.</p> |
