Abstract
A method and apparatus for removing an extruded profile shape from an extrusion press efficiently and economically during an extrusion operation. A first and second extrusion puller are mounted on suitable guide for movement along an extrusion line. One of the extrusion pullers receives and grips a profile shape as it is extruded from an extrusion press, and this puller exerts a pulling force on the profile shape. The first puller can pass off the profile shape to the second puller as the profile shape is extruded, thereafter the second puller would grip and pull the profile shape and the first puller would release its grip. When it is desired, or necessary to remove the profile shape from the extrusion press, the puller which is not gripping the shape grips the profile shape and a shear within the press shears off a butt portion of the billet. Then, both pullers, in tandem, apply a pulling force on the profile shape away from the extrusion press. The profile shape is stripped from the die. Thereafter, the first puller releases its grip and returns to receive another profile shape while the second puller moves the profile shape to further conditioning operations. Finally, the second puller returns to its home position and waits to receive the next extruded profile shape.
