A conveyor system lifts advancing signatures from a conventional conveyor, conveys the lifted signatures along an upright path of travel, turns the advancing signatures from the upright path of travel to a downward path of travel, deposits the advancing signatures from the downward path of travel back onto the conventional conveyor, and rotates the advancing signatures 180° about an axis which is parallel to their path of travel during either their upward path of travel or their downward path of travel so that the signatures are turned over when deposited back onto the conventional conveyor.
