Abstract
A device for cutting a plate or panel of porous construction material includes a movement structure that moves the plate or panel and includes at least one conveyor, and which is able to move in a direction (X). The device also includes a wire to cut the plate or panel and a structure for passing the wire in a direction (Y) perpendicular to the direction (X) of travel of the plate or panel. The device for cutting allows a cut to be made that greatly limits the waste and dust generated.
Claims20
A device for cutting a plate or panel of porous construction material, comprising:
- a conveyor configured to move the plate or panel in a first direction;
- a wire intended to cut the plate or panel;
- and
- a first reel and a second reel on which the wire is wound so as to pass the wire in a second direction perpendicular to the first direction, the first and second reels being slaved to each other by a servo control system,
- wherein the servo control system is configured to adapt a rotational speed of the first and second reels in real time to keep a linear speed and a tension of the wire constant during cutting, the servo control system being connected to optical sensors which measure a diameter of the first and second reels, position sensors which measure a position and a bending of the wire along the first direction, and a bending-measurement sensor which measures deformation of the wire along the first direction.
