Zusammenfassung:The present invention discloses a method of making a coated abrasive article (40), comprising: filling a plurality of formed abrasive particles into a plurality of apertures of a first precision apertured screen (58) to position the formed abrasive particles into a specified z-direction rotational orientation; positioning a coated backing having a make layer parallel to the first precision apertured screen surface containing the plurality of formed abrasive particles with the make layer facing the formed abrasive particles in the apertures; bringing the coated backing into contact with the formed abrasive particles in the first precision apertured screen (58) to adhere the formed abrasive particles to the make layer; and removing the first precision apertured screen (58), thereby leaving the formed abrasive particles having the specified z-direction rotational orientation on the coated backing.
