Four Deck Rotary Press with Pneumatic Unwind and Driven Surface Rewind
M.R. Snyder Company was contacted by a company who was struggling with an old and difficult to support control system. The press had different manufacturers for the control PLC, the drives, and the proprietary safety system as well. M.R. Snyder replaced these with a single, easy to support, totally integrated Siemens platform. The new system used a Siemens S7-1500 safety PLC, Siemens G120 drives, and Siemens Comfort Panel touchscreens. The new devices were retrofit into existing customer enclosures. M.R. Snyder oversaw and implemented all phases of the electrical upgrade.
