The fabric contains a polyester, it has undergone heat setting and relaxation, and its dimensions are stabilised in the warp direction, for which reason it has an extension less than 6.5 % for a tensile strength of 300 N per linear cm of width. Manufactured by the method, the fabric retains the desired width. It can be used for manufacturing abrasive strips and belts, which have a support fabric (20) made of polyester. A filling layer (22) is formed on its lower face, then a finishing layer (24) is formed on the latter. A filling layer (26) is formed on its upper face, then a prefinishing layer (28) is formed on the latter, which prefinishing layer itself carries a holding layer (30) in which the abrasive grains (32) are embedded, covered with a finishing layer (34). <IMAGE> |
