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.

A method for producing a hollow profile having a longitudinal profile axis, wherein the hollow profile comprises at least one of at least one cross-sectional change and at least one curved portion, said method comprising:
- a. moving a core having a longitudinal core axis in a translational manner along the longitudinal core axis relative to a system, which system includes at least a first and a second fibre feed, wherein the longitudinal core axis includes at least one change in direction and/or wherein the core includes at least one cross-sectional change along the longitudinal core axis;
- b. depositing unidirectional threads from the first fibre feed along the longitudinal core axis in order to form an axial fibre reinforcement;
- and
- c. winding threads from the second fibre feed around the core, which rotates around the core relative thereto, in order to form a first wound layer.
