The spin head is enclosed in a heated spinning beam and comprises a mixer, a distributor pump and a plurality of spinnerets. A feed device generates a secondary flow which is supplied to the main melt flow for the purpose of additive admixture. The secondary flow and the main melt flow are combined inside the spinning beam.
