Shoe presses are used in the production of many different grades of paper and board. They differ from conventional roll presses in that they offer a significantly longer nip width and dwell time. Shoe presses offer many different benefits, including higher dryness to the dryer section, improved bonding and sheet strength properties, and increased bulk. Understanding the design and operation of shoe presses will help with day-to-day operations and troubleshooting.
