A _________ roll press uses helical grooves cut into the bottom press roll that is in contact with the pressure felt. These _________ provide additional volume and a path for water transfer from the sheet through the press nip. Correct Answer Groove
In a plain press, two smooth rolls are used and the capacity to remove water depends on the void volume of the press felt(s) to receive the water. The first press is often a plain press and is often double-felted to receive more water.
