Abstract
An extrusion die mounted in a die holder is fitted onto the end of the press stem of an extrusion press by apparatus which has a swing arm which receives a die holder in a first position, then pivots to a second position where the die holder is aligned with the extrusion press stem, rotates the die holder so that it is correctly oriented relative to the press stem and then pushes the die holder axially onto the press stem.

Apparatus for fitting an extrusion die holder onto the press stem of an indirect extrusion press, the apparatus comprising:
- a stationary frame;
- a swing arm mounted on the frame and having an upper edge;
- two cylindrical rollers mounted for rotation at the upper edge of the swing arm;
- feed means for feeding die holders to the upper edge of the swing arm;
- means for pivoting the swing arm about an axis between a first position where the feed means feeds a die holder onto the arm so that the holder is supported on said upper edge and on one of the two rollers, and a second position where the die holder is supported on both rollers;
- drive means for driving both rollers in the same direction of rotation, when the swing arm is in said second position, to rotate the die holder;
- sensing means following the surface of the die holder as the holder rotates, and arranged to stop said drive means when the holder reaches a predetermined orientation;
- and
- a push-on device for pushing the oriented holder axially in a direction parallel to the pivot axis of the swing arm.
