Packing assembly, material exchange column, and method

A method for producing a packing assembly, comprising:

• providing a vessel;
• providing packing packets, wherein each packing packet comprises interconnected packing sheets;
• providing additional packing sheets;
• installing the packing packets in the vessel for forming at least one packing plate;
• and
• closing one or more gaps between packing packets by inserting the additional packing sheets between the packing packets in such a way that the at least one packing plate is pretensioned in a radial direction of the vessel against the latter, wherein both the interconnected packing sheets of the packing packets and the additional packing sheets inserted between the packing packets are arranged exclusively in or parallel to a common plane,
• wherein, for closing a gap arranged in or parallel to the common plane, the gap is closed by the insertion of the additional packing sheets between the packing packets, and
• wherein, for closing a gap arranged perpendicularly to the common plane and between two packing packets, the two packing packets are first displaced toward one another parallel to the common plane, packing sheets are removed from the displaced packing packets, and then the displaced packing packets are further displaced in a direction perpendicular to the common plane until the displaced packing packets facing the vessel contact the vessel, in order to form a gap that is arranged parallel to the common plane, wherein the sheets are removed such that, during the step of further displacing the displaced packing packets in a direction perpendicular to the common plane, contact with the vessel of the displaced packing packets facing the vessel is realized without forming a gap between the packing packets that is arranged perpendicular to the common plane, and wherein the gap that is formed and arranged parallel to the common plane is closed by the insertion of the additional packing sheets between the packing packets.
