1. An abrasive disc 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 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, wherein at least some of the beams extend in a direction intersecting a machine direction of the abrasive disc; and
wherein the textile fabric comprises on one side thereof a coherent abrasive area and 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.
