METHOD AND DEVICE FOR SPECIFIC INFLUENCE ON TECHNOLOGICAL PROPERTIES OF SEPARATE AREAS OF SHEET MATERIAL, PRELIMINARY SEALED MATERIAL IN THE VIEW OF NON-WOVEN CANVAS OR MATERIAL SEAM VIEW

摘要

1. A method for specifically influencing the technological properties of individual regions (2a) of a sheet material (2), according to which: a) a sheet material (2) or pre-compacted material (2 ') is fixed in the form of a non-woven fabric or material (2') in the form pulp on the working table (1), b) place at least one applicator (3) on the upper side and / or on the lower side of the sheet material (2) or material (2 ') in the form of a non-woven fabric or material (2') in the form of pulp, c) specifically move the specified at least one the applicator (3) from the upper side and / or from the lower side and injected under pressure an improving medium into partial areas of the sheet material (2), material (2 ') in the form of a non-woven fabric or material (2') in the form of a fibrous mass, in a predetermined quantity and under a given pressure, d) then, optionally, a pre-compacted material (2 ') is pressed in the form of a non-woven fabric or material (2') in the form of a fibrous mass to form a sheet (2) of a given thickness. 2. The method according to claim 1, wherein said at least one applicator (3) is sealed with respect to the upper side and / or lower side of the sheet material (2), material (2 ') in the form of a non-woven fabric or material (2') in the form of fibrous mass. 3. A method according to claim 1, wherein said at least one applicator (3) is moved along the upper side and / or lower side along the trajectories of any given shape. The method according to claim 2, wherein the enhancing medium is sprayed under pressure using at least one nozzle (6) for applying to the upper side and / or lower side of the sheet material (2), the material (2 ') in the form of a non-woven fabric and
