Abstract: A cutting table (10) with differentiated suction for the stabilisation of the material (14) to be cut, comprises a surface having a planar extension divided into a plurality of sectors (12) and surmounted by a permeable cover (18) on which said material is laid, The cover (18) rests on an underlying rigid structure (20) provided with quadrangular indentations (22) corresponding to said sectors (12) along which two apertures are made (24-26) for the alternate suction of air at high and low pressure by means of respective pumps (34-34?). Each of said sectors (12) is divided into two zones respectively used for high and low pressure suction by means of the intervention of specific valve groups (50).

Abstract: A device for the optical detection of the surface of plate-shaped materials (16) to be cut, especially suitable for continuous cutting machines or tables (10) including, at the top of a base (12), a cutting table (14) with a quadrangular square whereon said material to be cut is spread, through one or more cutting heads or units (20) carried by at least one beam (18) guided in sliding along one or more tracks (24) parallel or orthogonal to the long sides of the cutting table (14), characterised in that said device has at least one scanner (22) attached to said beam (18) or to a mobile support (28) parallel thereto.
