Patent number: 8360830Abstract: A grinding lamella (1) for being arranged on a rotatingly drivable grinding wheel (8), has at least two annular portions (4, 5, 6, 7, 24, 25, 26, 27, 34, 35, 36, 37, 44, 45, 46, 47) arranged at an angle (?) relative to one another. At least partially, the grinding lamellae (1) have a shape that deviates from the shape of a circular wheel with a central aperture. The grinding wheel (8) containing the grinding lamellae has at least one carrier element (2) and a least two such grinding lamellae (1) that partially overlap and, together, form an annular shape. If use is made of a pattern (14, 32) for a piece of material or a strip of material for producing the grinding lamellae (1), the grinding lamellae (1) are arranged side by side in the same direction so as to adjoin one another and offset relative to one another by 180°.Type: GrantFiled: February 28, 2007Date of Patent: January 29, 2013Assignee: Lukas-Erzett Vereinigte Schleif-und Fräswerkzeugfabriken GmbH & Co.
