Abstract: A die assembly (5) including: (i) a die plate (10) having an inlet surface (15) and an opposing discharge surface (35); (ii) an inlet (30) on the inlet surface (15) and a first axis of symmetry (A) extending through the inlet (30) and perpendicular to the inlet surface (15); (iii) a discharge port (45) on the discharge surface (35) and a second axis of symmetry (B) extending through the discharge port (45) and perpendicular to the discharge surface (35). The first and second axes are apart from, and parallel to, one another. The die assembly (5) includes (iv) an extrudate passage (42) fluidly connecting the inlet (30) and the discharge port (45). A third axis of symmetry (C) extends through the extrudate passage (42). The die assembly (5) includes (v) a nozzle (100) mounted in the die plate (10), the nozzle (100) having an injection tip (110) in the extrudate passage (42) at the discharge port (45); and (vi) the third axis of symmetry (C) intersects the first axis of symmetry (A) to form an acute angle.
