    Abstract: In some examples, an abrasive particle transfer system including a production tool comprising a dispensing surface and a back surface opposite the dispensing surface, wherein the production tool has cavities formed therein, wherein, on a respective basis, each of the cavities extends from a first opening at the dispensing surface through the production tool to a second opening at the back surface, and wherein the second opening is smaller than the first opening; abrasive particles removably disposed within at least some of the cavities such that a portion of each particle protrudes from the back surface through the second opening; and a transfer roll having an outer surface, wherein the production tool is guided along a web path such that the portion of the abrasive particles protruding from the back surface of the production tool contacts the outer surface of the abrasive particle transfer roll to displace the abrasive particles.

    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.

    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).
