The invention relates to a method for producing an especially panel-shaped vacuum insulation element which is wrapped in a film and is filled with a powder. According to the method, the unmolded, loose powder is filled, particularly poured, into the opening of a bag which is formed from a high-barrier film and is open on one side. A filter material that is permeable to air and impermeable to powder dust is fixed to the internal face of the film bag in the area of the opening of the filled film bag such that the interior of the bag is closed in a dust-tig...
1. A method for the production of a panel-shaped evacuated heat insulation element, enclosed in film of the form of a flat film bag (1) filled with an unmolded, loose powder (4), the method comprising the steps of: a) providing a filter material (8) which is folded or preformed in the shape of a trough with one open side face, the length of the trough corresponding to the width of the evacuated heat insulation element and the width of the trough corresponding to the thickness of the evacuated heat insulation element;b) in the area of an opening (6) on on...
