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.
Claims36
A spinner head comprising:
- a base;
- a cover aligned with and spaced from said base;
- a plurality of discrete elongate spaced heating elements positioned between said base and said cover and defining a perimetrical configuration;
- said base, said cover and said heating elements mutually defining a chamber for accommodating therein a solid non-solubilized feedstock material capable of undergoing physical transformation with the application of heat and force;
- and
- restricting means for restricting expulsion of said feedstock material from said chamber, said restricting means including a plurality of plates, each plate being removably insertable longitudinally in a space between said heating elements.
A flow restricting device for a use in a spinner head having an annular slotted processing wall through which feedstock material is expellable from a central chamber comprising:
- a substantially elongate plate having a pair of opposed sides, said plate being insertable in said slot, at least one of said plate sides including a plurality of radially extending grooves and, said grooves forming a pathway for said expelled feedstock material.
A flow restricting device for a use in a spinner head having an annular processing wall having longitudinal slots extending therethrough through which feedstock material is expellable comprising:
- a plurality of substantially elongate plates each having a pair of opposed sides, one of said plates being insertable into each said slot, each said plate sides being substantially smooth and having a thickness less then the thickness of said slot whereby each said plate divides said slot longitudinally forming a reduced pathway for said expelled feedstock material on both sides of said plate.
A method for restricting the flow of feedstock material through a spinner head having an annular slotted processing wall through which said feedstock is expelled, said method comprising:
- providing a plurality of substantially elongate plates each having a pair of opposed sides, each said plate sides being substantially smooth and having a thickness less then the thickness of said slot whereby each said plate divides said slot longitudinally forming a reduced pathway for said expelled feedstock material on both sides of said plate;
- inserting into each of said slots one of said substantially elongate plates.
