An apparatus and method for melt spinning polymeric yarns, wherein a main melt flow is generated by an extruder and supplied to a spin head. 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.

Apparatus and method for spinning polymeric yarns

An extruder for melting plastic granules which is designed as a two-stage system in an integrated structural unit with an extruder chamber having an extruder screw in a heatable housing, as well as with a drying chamber having a heated conveying screw with displacement elements which dry the plastic granules and axially convey them to the extruder chamber without compression. In a preferred embodiment, the conveying screw has a larger diameter than the extruder screw, and displacement elements of greater depth than the extruder screw.
