The Perfetto PRO compensating stacker can be used for integrated production in the mid-performance range. It forms the perfect stack in two-up and three-up production as well. The maximum speed is 16,000 cycles per hour. The universal size range of the Perfetto PRO is tailored to the market-leading saddle stitchers in its performance class. The compensating stacker can be fully integrated into the saddle stitcher’s control or into external systems.
