Abstract
The present disclosure relates generally to an extruder for producing an extrudate. The present disclosure relates more particularly to an extruder including an extruder body having at least one material inlet and an exit opening. A rotatable outlet is coupled to the exit opening of the extruder body and is configured to rotate as the extrudate is expelled from the extruder body.
Claims15
A system for producing a formed article, the system comprising:
- an extruder comprising:
- an extruder body comprising one or more material inlets each configured for the introduction of a material component of an extrudate comprising a polyurethane into the extruder body, a first one of the material inlets being coupled to a source of a polyol and a second one of the material inlets being coupled to a source of an isocyanate, and an exit opening, the extruder body being configured to mix the one or more material components of the extrudate, and to convey the mixture so formed to the exit opening, wherein the mixing and conveying includes allowing the polyol and the isocyanate to react to form the polyurethane;
- a rotatable outlet coupled to the exit opening of the extruder body, the rotatable outlet being configured to allow an extrudate to continue rotating as it leaves the rotatable outlet;
- and
- a drive mechanism coupled to the outlet and configured to impart rotation to the rotatable outlet,
- a receiving surface configured to receive the extrudate after it leaves the outlet, after having been rotated through a predetermined amount of rotation;
- and
- a shaping machine configured to receive the extrudate from the receiving surface and to shape the received extrudate into the formed article.

A system for producing a formed article, the system comprising:
- an extruder comprising:
- an extruder body comprising one or more matrix material inlets each configured for the introduction of a material component of a matrix material of an extrudate into the extruder body, a fibrous material inlet coupled to a source of fiberglass, and an exit opening, the extruder body being configured to mix the one or more material components of the matrix material and the fibrous material, and to convey the mixture so formed to the exit opening;
- a rotatable outlet coupled to the exit opening of the extruder body, the rotatable outlet being configured to allow an extrudate to continue rotating as it leaves the rotatable outlet;
- and
- a drive mechanism coupled to the outlet and configured to impart rotation to the rotatable outlet,
- a receiving surface configured to receive the extrudate after it leaves the outlet, after having been rotated through a predetermined amount of rotation;
- and
- a shaping machine configured to receive the extrudate from the receiving surface and to shape the received extrudate into the formed article.
