ABSTRACT:
A mechanism and method for producing a plurality of elongate filaments of plastic material from a die head which has a plastic flow chamber for receiving a flow of heated plastic material with the chamber leading to parallel small flow passages having individual tubes extending from the individual passages and having gas flow ducts positioned laterally outwardly of the die head for receiving a flow of heated gas with the ducts directed in a converging direction outwardly of the die head and permitting the opposed streams of gas to merge around the tubes and flow parallel thereto so that a high velocity stream of gas emerges with the plastic and attenuates the plastic stream for strength.
