ABSTRACT:
A fibrous board is formed by conventional water laid techniques such as the utilization of a Fourdrinier machine. After the board has formed and has been consolidated, it is subjected to a vacuum action to remove additional water from the wet board structure just prior to the time the wet board structure moves into an oven where final board drying is carried out.
