    Abstract: Abrasive articles and associated methods are shown that include one or more camouflaging layers that can be applied to a portion of the abrasive article. The one or more camouflaging layers can be applied over the size coat layer as a discontinuous colored layer covering a portion of the size coat layer. In an example, the camouflaging layer can be applied as a repeating pattern of one or more colors on the abrasive article. In an example, the camouflaging layer can be applied randomly to the abrasive article. The discontinuous layer can have a color markedly different than a color of the size coat layer and can be used to mask or minimize an appearance of particle imperfections or voids on the abrasive article. The discontinuous layer can be applicable to coated and non-woven abrasive articles in the form of sheets, discs, belts, pads, or rolls.

    Abstract: A coated abrasive article comprises a backing having first and second opposed major surfaces. A make layer is bonded to the first major surface. Agglomerate grinding aid particles are directly bonded to the make layer. At least a portion of the agglomerate grinding aid particles comprise grinding aid particles retained in a binder, and are arranged according to an open predetermined pattern. Abrasive particles are directly bonded to the make layer in spaces between the agglomerate grinding aid particles. A size layer is directly bonded to the make layer, agglomerate grinding aid particles, and abrasive particles. A method of making a coated abrasive article, in which the agglomerate grinding aid particles are deposited onto a curable make layer precursor prior to depositing abrasive particles onto the curable make layer precursor in spaces between the agglomerate grinding aid particles is also disclosed.

    Abstract: The present disclosure provides systems, devices, and methods for abrasive articles and manufacturing the same. A method includes receiving, at a shaped abrasive particle placement tool comprising cavities (1020), shaped abrasive particles (502, 504), determining whether a threshold number of cavities of the cavities (1020) includes a shaped abrasive particle situated properly therein, in response to determining there is not a threshold number of cavities of the cavities (1020) with a shaped abrasive particle (502, 504) situated properly therein, receiving, at the shaped abrasive particle placement tool, further shaped abrasive particles, and in response to determining that at least the threshold number of cavities of the cavities (1020) includes a shaped abrasive particle (502, 504) of the shaped abrasive particles situated properly therein, releasing the shaped abrasive particles (502, 504) from the shaped abrasive particle placement tool into a binding material (508) on a substrate (506) to adhere the shaped abrasive particles (502, 504) to the substrate (506).

    Abstract: Coated abrasive articles having spacer particles are formed by providing a production tool having a dispensing surface with a plurality of cavities, guiding the production tool past an abrasive particle feeder, dispensing shaped abrasive particles onto the dispensing surface and into the plurality of cavities of the production tool, guiding a resin coated backing sheet adjacent the production tool past a spacer particle feeder, and dispensing spacer particles onto the resin coated backing sheet and/or the production tool after the abrasive particle feeder prior to a deposit point for the shaped abrasive particles. The spacer particles are selected to have a thickness that is greater than a thickness of a resin coating of the resin coating backing sheet and a thickness and density once dispensed that are sufficient to substantially prevent the production tool from contacting the resin coated backing sheet at the deposit point.

A method includes receiving, at a shaped abrasive particle placement tool comprising cavities (1020), shaped abrasive particles (502, 504), determining whether a threshold number of cavities of the cavities (1020) includes a shaped abrasive particle situated properly therein, in response to determining there is not a threshold number of cavities of the cavities (1020) with a shaped abrasive particle (502, 504) situated properly therein, receiving, at the shaped abrasive particle placement tool, further shaped abrasive particles, and in response to determining that at least the threshold number of cavities of the cavities (1020) includes a shaped abrasive particle (502, 504) of the shaped abrasive particles situated properly therein, releasing the shaped abrasive particles (502, 504) from the shaped abrasive particle placement tool into a binding material (508) on a substrate (506) to adhere the shaped abrasive particles (502, 504) to the substrate (506).
