Claim 19:
20. An abrasive belt comprising a plurality of openings in the form of through holes, wherein
the abrasive belt comprises a textile fabric being formed of interconnected fabric yarns and has a uniform thickness,
a coherent abrasive area is formed on one side of the textile fabric, the plurality of openings are arranged in the coherent abrasive area in lines perpendicular to a machine direction of the abrasive belt, the machine direction being defined by a direction in which the abrasive belt is driven to circulate,
the plurality of openings are regularly spaced along a direction that follows the lines,
subsequent lines are offset from one another with respect to the position of their openings,
wherein the textile fabric is defined by beams, each of the beams being defined by multiple ones of the interconnected fabric yarns, the beams extending between and defining connection regions in which different ones of the beams connect with each other, the interconnected fabric yarns in each one of the beams being knitted, stitched, or woven between the connection regions, whereby the abrasive belt promotes an even sanding finish of a work piece.
