  1. Continuous melt flow through both filter heads. Initiation of fully automatic screen change when the adjustable limit pressure has been reached in filter head 1 in front of the screen. Valves 1.1 and 1.2 close and the space in front of the screen is depressurized. Wedges open in parallel and re-lease screen belt fixation. Melt flows continuously through filter head 2.
  2. The screen is guided by driven transport rollers until clean screen is in the filter zone again.
  3. Wedges close and screen is fixed and sealed again. Valves 1.1 and 1.2 open and melt flows into filter head 1 again.
