The present invention pertains to a modular block for the formation of suction surfaces in machines for the cutting of fabrics with a free blade with alternating movement. The block includes a first base element having structure for its installation and a second complete element having a plurality of bristles perpendicular to it. The two elements are superimposed and are attached firmly to one another. The two elements combined define lateral openings in the direction at right angles to the base of the bristles and are able to be connected to a suction apparatus for the formation of the vacuum among the bristles.
