The hide runs between two felts under high pressure applied by strong cylinders (up to 7 cylinders). Dollfus & Muller felts are resistant to high pressure, easy to guide for a quick running start and allow an easy maintenance. The bottom sammying felts are also available in black color for a reliable infrared surface measuring, and are then called black bottom felts.
