Method for manufacturing fibre-composite components, the method comprising the following steps: - providing a production unit for applying a fibre-composite material onto a component mould, ○ wherein the production unit has a positioning installation and an application tool disposed thereon, ○ wherein the positioning installation has a plurality of drive motors (9, 21, 26, 27, 28, 34, 38) which for positioning of the application tool in relation to the component mould are actuatable by means of a controller installation, and ○ wherein the production unit has at least two height-profile measuring sensors (56, 57) having an acquisition range which is directed towards the component mould; - applying a first web (B 51) of the fibre-composite material onto the component mould; - measuring a height profile in such a manner that at least part of the applied first web (B 51) lies in the acquisition range of at least one of the height-profile measuring sensors (56, 57); and - applying a second web (B 52, B 61) of the fibre-composite material onto the component mould in such a manner that the controller installation depending on the measured height profile actuates at least one of the drive motors (9, 21, 26, 27, 28, 34, 38), wherein the webs (B 51, B 61) are applied in opposite application directions (55, 55'), wherein ∘ two of the at least two height-profile measuring sensors (56, 57) are disposed beside one another on the application tool, and ∘ the application tool is rotated by 180° in relation to the positioning installation when the application direction (55, 55') is reversed. - providing a production unit for applying a fibre-composite material onto a component mould, ○ wherein the production unit has a positioning installation and an application tool disposed thereon, ○ wherein the positioning installation has a plurality of drive motors (9, 21, 26, 27, 28, 34, 38) which for positioning of the application tool in relation to the component mould are actuatable by means of a controller installation, and ○ wherein the production unit has at least two height-profile measuring sensors (56, 57) having an acquisition range which is directed towards the component mould; ○ wherein the production unit has a positioning installation and an application tool disposed thereon, ○ wherein the positioning installation has a plurality of drive motors (9, 21, 26, 27, 28, 34, 38) which for positioning of the application tool in relation to the component mould are actuatable by means of a controller installation, and ○ wherein the production unit has at least two height-profile measuring sensors (56, 57) having an acquisition range which is directed towards the component mould; - applying a first web (B 51) of the fibre-composite material onto the component mould; - measuring a height profile in such a manner that at least part of the applied first web (B 51) lies in the acquisition range of at least one of the height-profile measuring sensors (56, 57); and - applying a second web (B 52, B 61) of the fibre-composite material onto the component mould in such a manner that the controller installation depending on the measured height profile actuates at least one of the drive motors (9, 21, 26, 27, 28, 34, 38), wherein the webs (B 51, B 61) are applied in opposite application directions (55, 55'), wherein ∘ two of the at least two height-profile measuring sensors (56, 57) are disposed beside one another on the application tool, and ∘ the application tool is rotated by 180° in relation to the positioning installation when the application direction (55, 55') is reversed. ∘ two of the at least two height-profile measuring sensors (56, 57) are disposed beside one another on the application tool, and ∘ the application tool is rotated by 180° in relation to the positioning installation when the application direction (55, 55') is reversed.
