Abstract
PURPOSE:To provide an evenly finished surface to be ground and prevent said surface from being choked with grain or the like by constituting the irregular structure from fibrous materials and adhesives to be formed with concave portions cut out solvably by solvent and discrete concave and convex fibrous portions. CONSTITUTION:Fibrous density of convex portions 3 is approximately identical to that of concave portions 2 and uniform. Side surfaces 15 of convex portions exist as ends of fibers and the concave portions 2 are cut out solvably by solvent. The surfaces 14, 16 of convex and concave portions are formed with discrete fibers and the ratio of the area of concave portion surface 16 to that of surfaces 14, 16 is 20-80%. The number of individual concave portions 2 or convex ones 3 per unit area is 9-500 pieces/cm.
