A method for continuously forming a fiber mat for use in manufacturing fiberboard is disclosed including metering fibrous material, depositing the fibrous material onto a moving surface, forming a fiber mat from the fibrous material by applying adjustable rotary rolls to the surface of the fiber mat with the rolls being disposed along a predetermined direction and including a final adjustable rotary roll, in which a bulb of the fibrous material is formed prior to the final adjustable rotary roll which, in turn, defines the upper surface of the fiber mat, detecting the size of the bulb of fibrous material, and controlling the vertical position of the final adjustable rotary roll based on the size of the bulb of fibrous material. |
