Abstract
A method for producing a hollow filament package by winding at least one hollow filament onto a rotating body in a plurality of layers in the form of coils using a traversing filament guide device, so that the coils form an angle with the longitudinal axis of the body, wherein the speed of rotation of the body and the traverse speed of the filament guide device are adapted to one another in such a way that, per layer, a plurality of first coils are laid down side by side between the end sections of the body and, after each forming of a first hollow filament coil, the speed of rotation of the body and/or the traverse speed of the filament guide device is changed in such a way that second hollow filament coils are formed on the first or the second end section, the second coils forming an angle with the longitudinal axis of the core greater than the angle formed by the first coils.
