Abstract: An endless abrasive article comprising a substantially constant width, a flexible backing, and an abrasive layer comprising a layer of abrasive grains fixed onto the backing by an adhesive make coat, wherein the abrasive layer comprises a plurality of cavities arranged in a series of parallel rows, the cavities being substantially free of the adhesive make coat and substantially free of abrasive grains fixed onto the backing, individual cavities in a row are separated from each other by a first distance, adjacent parallel rows are separated from each other by a second distance in a direction parallel with the width, and wherein the parallel rows defining an inclined direction wherein an angle between the inclined direction and the edges of the abrasive article is substantially 8°, preferably in a range of 7.8 to 8.2°, which provides inclined segments of abrasive layer uninterrupted by any cavity between adjacent parallel rows.
