In a method and a production unit for producing fibre composite material components, a first web (B51) of the fibre composite material (2) is first applied to a component mould (3) by means of an application tool (41) arranged on a positioning device (4). A height profile of the applied first web (B51) is measured by means of a height profile measuring sensor (56, 57). During the subsequent application of a second web (B61) of the fibre composite material (2) to the component mould (3), a control device activates at least one drive motor of the positioning device (4) in dependence on the measured height profile in such a way as to avoid application errors, such as for example an overlapping of the webs (B51, B61). The webs (B51, B61) are applied in opposite application directions (55, 55'), the application tool (41) being rotated through 180 DEG relative to the positioning device (4) when there is a change of application direction (55, 55').
