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 coated abrasive article maker apparatus is disclosed comprising a first web path comprising a production tool and a second web path configured for a resin coated backing. The second web path is configured to guide the resin coated backing through the coated abrasive article maker apparatus with the resin layer positioned facing the dispensing surface. An abrasive particle feeder is positioned along the first web path and is configured to dispense abrasive particles onto the dispensing surface such that abrasive particles are removably disposed within cavities of the production tool. Abrasive particles are transferred from the plurality of cavities to the resin layer of the resin coated backing when the production tool is positioned adjacent the resin coated backing.

Abstract: A method of applying particles to a backing having a make layer on one of the backing's opposed major surfaces. The method including the steps of: supporting the particles on a feeding member having a feeding surface such that the particles settle into one or more layers on the feeding surface; the feeding surface and the backing being arranged in a non-parallel manner; and translating the particles from the feeding surface to the backing and attaching the particles to the make layer by an electrostatic force.

Abstract: Shaped ceramic articles can be obtained by screen printing the desired shapes from a dispersion of a precursor of the ceramic onto a receiving surface using a transfer assisted technique that applies a differential pressure, at least partially drying the screen printed shapes, and firing them to generate the shaped ceramic articles. Shaped abrasive particles made using lower viscosity sol gels that tended to flow or creep after the screen printing formation were found to have higher grinding performance over screen printed shaped abrasive particles made with higher viscosity sol gels.
