An extrusion line consists of one or more
extruders (generally with a vented barrel so that no drying is
necessary), a slit die or profile die, a calender for smoothing or
profiling the extrudate, a cooling section, a take-off unit and a
fabricating unit (sawing, punching or cutting device), with which
the extrudate can be cut to the desired length. The net result is
sheet, semi-finished products or
profiles. |
