X-Shaped packing layers and method of making

摘要

The packing can be used for mixing or for exchange processes in exchange columns. The packing comprises at least one group of layers perpendicular to the column axis which has deflecting surfaces connected to a central connecting bridge and which are bent outwardly of the bridge in alternating fashion to define a X-shape. The adjacent layers can be provided with outer bridges which are bent around to form hook-shape portions for engaging about an adjacent layer. The packing can be produced by simple stamping and bending steps.
