Abstract
A grinding product and a method of making same. The grinding product comprises a woven or knitted cloth of multifilament threads (1) whose fibers (2) form projecting loops (3), and separate agglomerates (4) of grinding material applied to the loops. During the grinding, different sides of the agglomerates (4) come into contact with the surface to be ground, which prolongs the service life of the grinding product. The agglomerates also form a gap between the cloth and the surface to be ground, through which gap the grinding dust can be removed.
Claims6

- and a grinding agent (4) applied as separate agglomerates on at least another essentially even surface of the cloth, wherein the projecting thread parts comprise loops (3) of threads (1) of the cloth, or of fibres (2) of such threads.
