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.
Method for filling hollow-section strips, wherein free-flowing fill material is introduced from a storage tank into the hollow-section strips, the method comprising detecting the amount of the fill material that is introduced into the hollow-section strips by detecting the amount of the fill material removed from the storage tank;
Device for implementing a method for filling hollow-section strips, wherein free-flowing fill material is introduced from a storage tank into the hollow-section strips, the method comprising detecting the amount of the fill material that is introduced into the hollow-section strips by detecting the amount of the fill material removed from the storage tank, said device comprising a storage tank for fill material, a piston that can move in the storage tank, a system for loading the piston with a preset pressure, line, which connects the storage tank to the hollow-section strip that is to be filled, and a system for detecting the travel distance that pushes the piston back in the storage tank when fill material is removed.
