ABSTRACT:
Articles (12) are loaded onto a movable article holder such as pedestals (18) mounted to a rotary table (20). The table is indexed to advance the articles (12) first to a centering station (41) and then to a work station (49) which may be, for example, a lead frame bonder. At the centering station (41) a typical centering mechanism (22) urges the articles to a predetermined center location. While the centering mechanism may be adjusted to and fixedly located in a position to center the articles (12) to a theoretical center removed by precisely one step or a multiple thereof from the bonding position, the centering station (41) provides for tangentially shifting the theoretical center with respect to the table (20). Any shift of said theoretical center is made to offset an anticipated error of alignment of the articles, even though such error may be unique to each of the pedestal positions.
