An apparatus for adjusting a swing arc and centering of a swinging director chute during separating, folding, stacking and transporting a continuous web that allows stacks of web that are relatively large (four-feet-high or more) to be generated at high speed directly beneath the folding mechanism and to be transferred as complete, discrete stacks to downstream locations and stack utilization devices without interrupting the ongoing, upstream stack-folding and stack-formation process. The apparatus includes a lever arm, interconnected with the swinging director chute, and a connecting rod having a first pivot end and a second pivot end. The first pivot end is adjustable movable along the lever arm. A drive arm connected to the second pivot end includes a lead screw. The lead screw can be operatively connected to an index wheel having a plurality of directed posts and a movable pawl that advances the index wheel.
