A coated abrasive article maker apparatus comprising: a production tooling in the form of an endless belt having a dispensing surface with a plurality of cavities, wherein at least a portion of the plurality of cavities is missing in a pattern transition zone of the production tooling; at least one roller (420, 430, 432, 434, 436, 438) configured to guide the production tooling through the coated abrasive article maker apparatus, the at least one roller including at least one drive roller for pulling the endless belt in a direction of travel; an abrasive particle feeder positioned adjacent the production tooling so as to dispense shaped abrasive particles onto the dispensing surface and into the plurality of cavities of the production tooling; a resin coated backing guide configured to guide a resin coated backing through the coated abrasive article maker apparatus in the direction of travel, the resin coated backing positioned to receive shaped abrasive particles from the plurality of cavities of the production tooling at a deposit point; means for detecting the pattern transition zone as the production tooling moves in the direction of travel and for providing pattern transition zone detection data; and at least one controller configured to receive the pattern transition zone detection data and configured to control at least one of a speed of rotation of the drive roller and a speed of the resin coated backing guide in accordance with the pattern transition zone detection data, whereby a speed of at least one of the production tooling and the resin coated backing is adjusted as the detected pattern transition zone passes the deposit point so as 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. a production tooling in the form of an endless belt having a dispensing surface with a plurality of cavities, wherein at least a portion of the plurality of cavities is missing in a pattern transition zone of the production tooling; at least one roller (420, 430, 432, 434, 436, 438) configured to guide the production tooling through the coated abrasive article maker apparatus, the at least one roller including at least one drive roller for pulling the endless belt in a direction of travel; an abrasive particle feeder positioned adjacent the production tooling so as to dispense shaped abrasive particles onto the dispensing surface and into the plurality of cavities of the production tooling; a resin coated backing guide configured to guide a resin coated backing through the coated abrasive article maker apparatus in the direction of travel, the resin coated backing positioned to receive shaped abrasive particles from the plurality of cavities of the production tooling at a deposit point; means for detecting the pattern transition zone as the production tooling moves in the direction of travel and for providing pattern transition zone detection data; and at least one controller configured to receive the pattern transition zone detection data and configured to control at least one of a speed of rotation of the drive roller and a speed of the resin coated backing guide in accordance with the pattern transition zone detection data, whereby a speed of at least one of the production tooling and the resin coated backing is adjusted as the detected pattern transition zone passes the deposit point so as 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.
