    Abstract: A method of converting a plastics material into a yarn comprises heating the material to melt it and pumping the melted material through an extrusion die (114) to form an extruded filament (116). The extruded filament is cooled and passed through a first draw roller assembly (122) while elevating the temperature of the filament. The filament (116) is heated in a heating zone (126) as it exits the first draw roller assembly. Thereafter the filament is passed through a second draw roller assembly (134) operating at a different linear speed to the first draw roller assembly (122). The filament (116) is spooled after exiting the second draw roller assembly (134).
