  • Surface processing abrasive body, support provided with said body and machine comprising the processing abrasive body and support
    Patent number: 6830506
    Abstract: Abrasive body (1) capable of being used in surface processing devices that has an active face (2a) provided with appropriate means of abrasion (3) intended to perform finishing operations on the surface of an object when the said body is set in motion. The abrasive body has a predetermined number of substantially passing cuts (6) defined by the respective flaps (7, 8) lying side by side. When the abrasive body is set in motion on an object to be processed, flaps (7, 8) deform in such a manner as to create appropriate opening that will permit the abraded dust particles to be removed solely and exclusively from that part of the abrasive body actually in contact with the object (FIG. 2).
