  • Patent number: 5078366
    Abstract: A guardrail extruder terminal for flattening a folded or W-beam guardrail and bending the guardrail to dissipate the energy of a vehicle impacting the end of the guardrail includes a feeder chute. The feeder chute is provided with an inlet in which the guardrail is positioned. The feeder chute extends into a terminal housing, and is in communication with an extruder or flattening throat. The flattening throat is of a smaller width than the feeder chute to flatten the guardrail. A bending member is also provided in the terminal to bend the guardrail in an curvilinear arc away from the impacting vehicle. Also included is a cable anchor releasably mounted on the guardrail. A cable extends from the cable anchor to a first post located at the end of the guardrail. The cable anchor includes lugs that release from the guardrail upon engagement of the extruder terminal with the cable anchor.
