Abstract
A device for filling spacer frames with hollow-section strips has a storage tank for free-flowing, hygroscopic fill material, such as a molecular sieve. A line that leads to the spacer frame to be filled extends from the storage tank and empties into a fill opening in the wall of the spacer frame. The amount of the fill material poured into the spacer frame is determined by the amount of the fill material removed from the storage tank being detected. The amount of the fill material removed from the storage tank is detected by measuring the travel of a piston that rests with pressure on the fill material in the storage tank. The degree of filling is verified by the amount of the fill material removed from the storage tank being compared to the preset amount of the fill material that is to be poured into the spacer frame.
