Abstract
The present invention relates to an apparatus for the extrusion of plastic profiles with an extruder having an extruder flange, an extrusion die with a die flange through which the extrusion die is detachably connectable with the extruder flange, a fastening element with the two halves which is arranged to embrace the extruder flange and the die flange, a tensioning element in order to press the two halves of the fastening element against the flanges. An improved function is achieved in such a way that the two halves of the fastening element are fastened swivelably on the extruder and that they are mechanically coupled in order to perform an oppositely directed swiveling movement.
