| 摘要 |
The present invention relates to an abrasive article (100) comprising an aligned row of connected abrasive sheet members (102, 104, 106) each having a main portion (112), an aperture (22) formed in the main portion, and a plurality of arm portions (120-154) perimetrically spaced about the main portion at a constant angle with respect to each adjacent arm portion. The sheet members are formed to enable the aligned row to be Z-folded such that the apertures of each respective sheet member are substantially in register, and the arm portions of each abrasive sheet member are angularly offset with respect to the arm portions of each immediately adjacent abrasive sheet portion by one-half of the angle between each of the arm portions. <IMAGE> |
