Abstract
A device and a method for specifically influencing the technological properties of individual regions of a sheet-like material are provided, including the following steps: a) fixing the sheet-like material or a pre-compacted material nonwoven or a material fiber cake on a workbench, b) placing at least one applicator on the upper side and/or the underside of the sheet-like material, the material nonwoven or the material fiber cake, c) specifically moving the at least one applicator on the upper side and/or the underside and pressing an improving medium into partial regions of the sheet-like material, the material nonwoven or the material fiber cake in a predetermined amount and under a predetermined pressure, d) optionally, subsequently pressing the pre-compacted material nonwoven or the material fiber cake to form a sheet of the desired thickness.
