Digital AC and DC Drive System
 From simple 3-drive controls for the unwind, main and rewind sections of a simple rotogravure press, through 5-drive systems for rotogravure presses with infeed and outfeed sectional drives or 7-drive systems for high-speed presses with controls for turrets and auto-splicers. The drive options could vary from all-Digital DC systems to a mix of AC and DC systems to full-vector controlled AC systems, with precise speed-feedback and dancer / tension control loops.
