发明名称 Method for filling and packing insulating powder in the walls of a cabinet body
摘要 A boxlike body (10) with a rear wall (12) and four side walls (14) is brought into a fixture (34) with the free edges (22) of the side walls pointing downwards. The walls of the body are filled with insulating powder by blowing the powder into the rear wall (12) by gaseous medium of a first pressure. The powder is then packed by gaseous medium of a second pressure, which is higher than the first pressure, being let into the rear wall. During the filling and packing the media is let out via a filter element (24) arranged at the free edges (22) of the side walls. After the filling and packing the media is evacuated from the walls through the filter element (24). The body can then be used as a so-called vacuum insulation in a refrigerator or freezer.
