  • Patent number: 6116880
    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.

  • Patent number: 5851454
    Abstract: A spinner head is used for spinning and processing feedstock material. The spinner head includes spaced tubular heating elements which are covered by annular housing that forms a material processing wall. The annular housing contains radially spaced slots which provide a passage way for the material to be expelled from the spinner head. Each slot contains a flow restricting insert removably insertable therein. The inserts include radially extending grooves which channel the feedstock material as it exits the spinner head. The insert further include latches extending therefrom which secure the inserts in the spinner head upon rotation.
