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.
