Abstract
In a process for the production of a flame retardant and/or strengthened fiberboard, a tailored fiberboard is charged on a processing device at first. Subsequently, a flame retardant and/or strengthening agent is applied to the top side of the fiberboard. The agent applied is sucked or pressed into the fiberboard. This is achieved by generating a pressure difference between the top side and bottom side of the fiberboard.
