Abstract
An abrasive belt is provided which comprises a textile fabric being formed of interconnected yarns, and a coherent abrasive area formed on one side of the textile fabric, wherein the abrasive belt further comprises a plurality of regularly distributed openings in the form of through holes. The abrasive belt allows for a homogenous distribution of the abrasive material and thus an even sanding finish as well as for an appropriate dust removal and appropriate mechanical properties.
Claims23
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.
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.
