1. An abrasive belt comprising:
a textile fabric being formed of interconnected fabric yarns, the textile fabric being 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; and
a coherent abrasive area that is a single, interconnected abrasive area that is continuous, wherein the coherent abrasive area is configured to sand or abrade a work piece, wherein the coherent abrasive area is formed on one side of the textile fabric,
wherein the coherent abrasive area comprises a plurality of regularly distributed openings in the form of through holes, each perimeter portion of each respective one of the through holes being defined by one of the connection regions or by the interconnected fabric yarns that are knitted, stitched, or woven in one of the beams extending between two of the connection regions that define perimeter portions of the respective one of the through holes, whereby the coherent abrasive area defines a uniform thickness of the abrasive belt, whereby the abrasive belt promotes an even sanding finish of the work piece.
