Abstract: The present invention provides a dispense head system for continuous extrusion of thermoplastic materials, e.g. into filaments or fibres. The dispense head system comprises - an input section for receiving the thermoplastic material in granular or powder form, - a feed pipe for transporting the thermoplastic material received in the input section towards an output port of the feed pipe, - a heatable barrel for receiving transported thermoplastic material from the feed pipe and rendering it viscous, and - an output to the heatable barrel for extrusion of the viscous thermoplastic material. In embodiments of the present invention, the dispense head system furthermore comprises a transfer zone located at the output port of the feed pipe and adapted for controlled preheating of the thermoplastic material.
