The invention relates to a method for preparing for a change of material in an extrusion device (10) for a film machine comprising at least one feed device (20) for feeding a feedstock (E) for an extruder (30), comprising the following steps: - predetermining an end of a production order of an extrusion device (10), - specifying a reduced changing filling level (WF) for the at least one feed device (20), - maintaining the filling level (F) of the at least one feed device (20) at the reduced changing filling level (WF) for the further production with the extrusion device (10). 本发明涉及种在制膜机用挤出设备(10)中准备物料转换的方法，该挤出设备具有至少个用于给挤出机(30)供给装料(E)的供料装置(20)，具有以下步骤：-预先确定挤出设备(10)的生产订单的结束，-设定用于所述至少个供料装置(20)的降低的转换料位(WF)，-将所述至少个供料装置(20)的料位(F)保持在所述降低的转换料位(WF)以便用该挤出设备(10)继续生产。
