Abstract (en)
[origin: WO8911357A1] Containers of explosive liquids can be prevented from exploding by filling the containers with meshes made from metal foil which occupies a negligible fraction of the volume of the container although it must completely fill the container. In order to refill the containers, the rib mesh (1) must consist of sufficiently small, spherical bodies (24). The invention also deals with the production of these filling bodies (24) from aluminium strip expanded into a mesh. The aluminium strip is first passed through a calibration opening (4) which compacts it into a bar (2) of circular cross-section which is then compacted perpendicularly to its length and continuously transported in the longitudinal direction as it is being squeezed. The front piece of the bar is then detached and pressed in a mould with a hemispherical bottom (21) by a die with the same inner contour to form a spherical filling body.
