A polymer melt to the nozzle openings to extrude the polymer melt downstream from the melt openings as polymer filaments and compressed air to the compressed-air openings to form air jets issuing downstream from the compressed-air openings between the polymer filaments. Only the polymer melt and no air is supplied to the melt openings such that only the polymer melt issues from the melt openings. Only compressed air and no polymer melt is supplied to the compressed-air openings such that only the compressed air issues from the compressed-air openings.
