The invention relates to a method for adjusting an extrusion die in an
extruder by recording at least one master flow curve (40, 41) in a first
extruder to which the extrusion die is optimized, in which curve the
volume flow is entered over the pressure, which master flow curve (40, 41)
is obtained in a measuring channel (20) which branches off in the
extruder, the extrusion die or in any interposed adapter part from the
flow channel (4), and the repeated recording of flow curves (30, 31) in
the same or similar measuring channels (20) as in the first extruder after
the assembly of the extrusion tool in the extruder to be checked and
adjusted, and the purposeful change of process parameters for such a time
until the flow curves (30, 31) correspond to the master flow curves (40,
41) within predetermined tolerance ranges.
