ABSTRACT:
Apparatus for aligning a moving stream of overlapping signatures includes a pair of elongated endless jogger belts mounted on supporting bases on opposite sides of said moving stream. Each belt is formed of resilient flexible sheet material mounted on edge with an inside run adapted to engage the edge of the signatures as they move between the belts. A final portion of each inside belt run is aligned parallel with the stream of signatures and spaced from the opposite belt by a distance determined by the size of the signatures. Each belt run has an entry portion joining a final portion and the spacing between the entry end of the belts is greater than the spacing between the belts at the discharge end in order to accommodate misalignment of the signatures in the stream initially entering between the belts. One of the bases is secured in fixed relation to the stream and the other base is resiliently biased toward the belt on the fixed base to resiliently engage the adjacent edges of the signatures and move the signatures into alignment with the opposite edges biased against the belt on the fixed base. The belts are driven at a speed equal to that of the moving stream of signatures.
