Zusammenfassung:	The invention relates to a method for impregnating at least one fibre bundle (11) with a high-viscosity plastics material (13), said method comprising the following steps: -providing at least one fibre bundle (11) for impregnation, formed of a multiplicity of continuous fibres, and providing a plastics material (13), melted at a mandated operating temperature and of high viscosity, and -impregnating the fibre bundle (11) with the plastics material (13), by guiding the fibre bundle for impregnation continuously through an impregnation cavity (12), filled with the melted plastics material (13), *-where during impregnation of the fibre bundle, the melted plastics material within the impregnation cavity is contacted with a surface (15) of at least one oscillation generator (14) in such a way that sonic energy is introduced by said oscillation generator into the melted high-viscosity plastics material in the impregnation cavity.
