    Abstract: A coated abrasive belt (100) includes a belt backing (110) and an abrasive layer disposed thereon. The abrasive layer comprises abrasive elements (160) secured to at least a portion of a major surface of the belt backing (110) by at least one binder material. The abrasive elements are disposed at contiguous intersections of horizontal (192) and vertical lines (194) of a rectangular grid pattern. Each abrasive element has at least two triangular abrasive platelets (130), each having respective top and bottom surfaces connected to each other, and separated by, three sidewalls. On a respective basis, one sidewall of the triangular abrasive platelets is disposed facing and proximate to the belt backing A first portion of the abrasive elements is arranged in alternating first rows (16) wherein the triangular abrasive platelets are disposed lengthwise aligned with the vertical lines (194). A second portion of the abrasive elements is arranged in alternating second rows (168) wherein the triangular abrasive platelets (130) are disposed lengthwise aligned with the horizontal lines (194). The first and second rows repeatedly alternate along the vertical lines. Methods of making and using the coated abrasive belt are also disclosed.

    Abstract: In some examples, an abrasive particle transfer system including a production tool including a dispensing surface with a plurality of cavities formed therein; abrasive particles removably disposed within at least some of the cavities; and a nonwoven substrate having an outer surface opposing the dispensing surface of the production tool, wherein the dispending surface of the production tool is configured to apply a compressive force to the outer surface of the nonwoven substrate to compress the nonwoven substrate from a first thickness to a second thickness, wherein, while the nonwoven substrate is compressed to the second thickness by the production tool, the abrasive particles are transferred from the plurality of cavities to the nonwoven substrate.

    Abstract: According to one embodiment, a method of making an abrasive layer on a backing is disclosed. The method can comprise: providing dispensable magnetizable abrasive particles and a distribution tool, wherein the distribution tool is configured to receive the magnetizable abrasive particles therein, and wherein the distribution tool is configured to impart at least one of a predetermined orientation and alignment of the magnetizable abrasive particles, positioning a backing adjacent to the distribution tool and spaced therefrom by a gap, applying a magnetic field to at least the backing and a portion of the gap between the backing and the distribution tool, and transferring the magnetizable abrasive particles from the distribution tool to a first major surface of the backing, wherein the magnetic field is applied during the transfer of the magnetizable abrasive particles.
