<p>Method and apparatus for exchanging a die holder (16) of an extruder (11), which is tightly pressed from the bottom against a lower surface of an extrusion head (13) by a press member (32,33). The pressing force of the press member (32,33) is reduced to form a gap between a used die holder and the extrusion head. The used die holder (16) and a next die holder (16) positioned collinearly with each other are moved simultaneously and longitudinally, while slidingly contacting both of these die holders (16) with the press member (32,33), so as to eject the used die holder (16) from the press member (32,33) and to deliver the next die holder (16) onto the press member (32,33). The next die holder (16) is then tightly pressed from the bottom onto the lower surface of the extrusion head (13) by the press member (32,33).</p> |
