ABSTRACT:
An extrusion head is provided in which molten polymeric material is formed into fibres by providing individual air streams for each orifice of a plurality of extrusion orifices formed in a straight line across the width of the head to draw out and convey individual polymeric material fibres from polymeric material extruded from each orifice, the individual fibres being separated from each other by the individual air streams to prevent coalescing of the fibres to form bundles while they are still molten. Each orifice is formed at the line of intersection of two sloping surfaces of a unitary wedge shaped body and preferably has a circular cross section in the elevational view and a part-elliptical cross section in the plan view to allow metering of the extruded molten material into the air streams over a flow path immediately upstream of the line of intersection.
