Abstract: A method for producing wound hollow profiles having variable curvatures and cross-sections. In this case, a core having at least one curvature or cross-sectional change is moved in a translatory manner relative to a system having at least a first and a second fibre feed which cause the formation of an axial fibre reinforcement and at least one first wound layer.
