    Abstract: The method generally involves the steps of filling the cavities in a production tool each with an individual abrasive particle. Aligning a filled production tool and a resin coated backing for transfer of the abrasive particles to the resin coated backing. Transferring the abrasive particles from the cavities onto the resin coated backing and removing the production tool from the aligned position with the resin coated backing. Thereafter the resin layer is cured, a size coat is applied and cured and the coated abrasive article is converted to sheet, disk, or belt form by suitable converting equipment.

    Abstract: A structured abrasive article comprises a backing having first and second opposed major surfaces and an abrasive layer securely bonded to the first major surface of the backing. The abrasive layer comprises shaped abrasive composites. Each shaped abrasive composite has four sides, a height, and abase that faces the first major surface of the backing. The shaped abrasive composites have an average height of 410 to 650 microns and an average side length at the base of 550 to 1450 microns. The shaped abrasive composites comprise non-magnetizable shaped abrasive platelets that have an average side length of 150 to 350 microns and an average thickness of 40 to 120 microns. Methods of making and using are also disclosed.

    Abstract: A coated abrasive article maker apparatus including a first web path guiding a production tool such that it wraps a portion of the outer circumference of an abrasive particle transfer roll; a second web path for a resin coated backing guiding the resin coated backing such that it wraps a portion of the outer circumference of the abrasive particle transfer roll with the resin layer positioned facing the dispensing surface of the production tool this is positioned between the resin coated backing and the outer circumference of the abrasive particle transfer roll; and wherein abrasive particles are transferred from cavities in the production tool to the resin coated backing as the resin coated backing and the production tool traverse around the abrasive particle transfer roll
