发明名称 FILTER CHANGING DEVICE
摘要 The device includes two coaxial filters in a cylindrical body positioned in the flow line perpendicular to the direction of discharge of a plastic extruder. By merely rotating the cylindrical body on its axis, one of the filters is connected with the extruder discharge while the other filter is disconnected from the extruder discharge and may be opened for cleaning by removing an end plug.
