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.
