Abstract
A spinner head provides for the production of melt-spun product. The spinner head includes a base and a cover spaced from the base. A plurality of discrete spaced apart elongate heating elements are positioned between the base and the cover and define a chamber for accommodating feedstock material therein. An elongate generally annular housing having plural circumferentially spaced cylindrical passages extending therethrough is positionable over the heating elements. The housing defines a plurality of circumferentially spaced fins projecting radially inward. Each of the fins have tapered sidewalls which generally converge as the fin extends radially inward. The sidewalls of adjacent fins cooperate to define longitudinal radially-directed slots between the cylindrical passages so as to permit passage of the feedstock material therethrough.
