Abstract
A thermoplastic extrusion die is disclosed. The thermoplastic extrusion die includes a housing, and a resilient or elastomer insert having an inlet through the housing, and a passage through the resilient insert. Embodiments have a mechanical locking mechanism configured to communicate physical pressure to the resilient insert thereby narrowing the passage for contact with traversing rovings.
Claims18
A thermoplastic extrusion die, comprising:
- a housing having a conical-shaped inlet end and a cylindrical-shaped body, the housing formed of a rigid material, wherein the conical-shaped inlet end comprises an opening;
- a resilient insert having a passage therethrough in coaxial alignment with the opening, the passage extending in an extrusion direction, wherein the resilient insert comprises a hollow cylindrical-shaped downstream body integrally formed with a hollow conical-shaped upstream body, wherein the passage of the resilient insert is defined by a hollowness of the hollow conical-shaped upstream body and the hollow cylindrical-shaped downstream body;
- and wherein the opening of the housing has a diameter larger than a diameter of the passage.
