Abstract: A method of transferring a shaped particle to a substrate includes providing a scrim of at least two elongate strands periodically joined together at flexible bond regions to form an array of apertures between the strands. The scrim is extended along at least one direction to increase the minimum dimension of the apertures. Shaped particles are applied to the extended scrim and at least a portion of the shaped particles enter in at least some of the apertures therein. The extended scrim is relaxed and frictionally retains the particles between the elongate strands. The particle loaded scrim is extended along at least one direction to release and transfer the shaped particles to the substrate in a predetermined orientation.

Abstract: Magnetizable agglomerate abrasive particle can comprise constituent abrasive particles retained in a binder material. The magnetizable particles and the constituent abrasive particles are unassociated, and wherein the magnetizable particles have a Mohs hardness of 6 or less. Magnetizable agglomerate abrasive particles can also comprise magnetizable abrasive particles retained in a binder material, wherein each magnetizable abrasive particle comprises a respective ceramic body and a magnetizable layer disposed on at least a portion of the ceramic body. Pluralities of abrasive particles are also disclosed. Methods of making, and abrasive articles including the magnetizable agglomerate particles are also disclosed.

Abstract: An abrasive article comprises abrasive particles adhered to a substrate by a binder material comprising an at least partially cured resole phenolic resin and an aliphatic tack modifier. The amount of resole phenolic resin comprises from 60 to 98 weight percent of the combined weight of the resole phenolic resin and the aliphatic tack modifier. A method of making the abrasive article is also disclosed.

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).

Abstract: Apparatus includes a production tooling having a dispensing surface with a plurality of cavities and formed into an endless belt. An abrasive particle feeder dispenses shaped abrasive particles onto the dispensing surface and into the plurality of cavities. A resin coated backing receives shaped abrasive particles from the cavities of the production tooling at a deposit point. A detecting device detects a pattern transition zone as the production tooling moves in the direction of travel and provides pattern transition zone detection data to one or more controllers to control a speed of the production tooling and/or a speed of the resin coated backing as the detected pattern transition zone passes the deposit point to change a pattern density of the shaped abrasive particles in a portion of the resin coated backing corresponding to the pattern transition zone of the production tooling.
