Abstract: A device is for assembling a modular cutting support element on a cutting support batten of a conveyor cutting machine for cutting sheet materials, and includes a cutting support batten, at least one modular cutting support element comprising a plurality of bristles each having a foot secured to a baseplate and a head opposite to the foot, and means for vertically holding by magnetism at least a second lateral end of the baseplate of the modular cutting support element on at least a second lateral end of the cutting support batten.

Abstract: A method for determining components of a mechanical action torsor at the guiding point of a cutting blade for a cutting machine, the blade being guided in a presser foot of a cutting head of the machine, such that the method includes the positioning of a five-component dynamometer on the presser foot, the dynamometer comprising a plurality of sensors for determining a frontal force, a lateral force, a rolling moment, a pitching moment and a yawing moment of the cutting blade, the establishment of a calibration matrix of the dynamometer, and the determination of the forces in three dimensions to which the cutting blade is subjected, on the basis of the measurements obtained by the sensors and the calibration matrix.
