Abstract: Horizontally conveyed flat glass articles are halted and oriented in a precise location. Vertical stop pins removably affixed to a table attached to one end of the apparatus arrest the leading edge of the moving article whereupon pins removably mounted in a pair of transversely movable tables advance toward the article substantially normal to its arrival direction, thus engaging the edges of the article and orienting it in a vise-like manner. Lastly, adjustable pins mounted in a vertically and longitudinally moving table engage the trailing edge of the article and urge it toward the stop pins, thus orienting and aligning the article in a precise position relative to a fixed reference point. The apparatus is particularly adapted to the precise orientation and alignment of pattern cut sheets of glass to be removed from a conveyor platform by a robot.
