Abstract
An extruder assembly has a frame with upstream and downstream ends. A barrel assembly on the frame has a passage. At least one material advancing component resides at least partially within the passage and is configured to be turned around an operating axis to thereby cause material to be conveyed from a passage inlet to a passage outlet. A drive assembly turns the at least one material advancing component around its operating axis and has a motor on the frame situated so that at least a part of the motor is in lengthwise overlapping relationship with the barrel assembly. The drive assembly is configured to turn the one material advancing component around its operating axis at a speed of at least 300 rpm.
Claims21
An extruder assembly comprising:
- a frame having an upstream end and a downstream end;
- a barrel assembly on the frame having a length and a passage with an inlet and an outlet;
- at least one material advancing component residing at least partially in the barrel assembly passage and configured to be turned around an operating axis to thereby cause material to be conveyed from the barrel assembly passage inlet to the barrel assembly passage outlet;
- and
- a drive assembly for turning the at least one material advancing component around the operating axis,
- the drive assembly comprising a motor on the frame situated so that at least a part of the motor is in lengthwise overlapping relationship with the barrel assembly,
- wherein the drive assembly is configured to turn the at least one material advancing component around its operating axis at a speed of at least 300 rpm.
