ABSTRACT:
An extrusion pulling apparatus including an extrusion run-out table and an extrusion puller which is mounted for reciprocal movement along the run-out table. The extrusion puller has an upper jaw mounted for vertical reciprocal movement between clamping and release positions on a support frame and a lower jaw mounted for reciprocal lateral movement between clamping and release positions also on the support frame. The lower jaw is also mounted for vertical movement with respect to the support frame. A stripper finger is mounted on the puller adjacent the upper and lower jaws when the jaws are in the clamping position and is movable laterally to push extrusions toward a cooling table when the lower jaw moves in an opposite direction to strip the extrusions from the lower jaw and to push one end of the extrusions from the extrusion line.
