Abstract
A plant for producing a structured cross-channel packing element. The structured cross-channel packing element comprises at least two adjacent layers made of expanded metal sheets each comprising periodic deformations. The plant comprises a stretching machine configured to cut and stretch a metal sheet to form one of a plurality of first expanded metal sheets, a calibration machine configured to roll the first expanded metal sheets to a desired thickness, a sheet storage unit configured to directly receive each of the first expanded metal sheets rolled in the calibration machine, a forming machine configured to form each of the first expanded metal sheets to form the expanded metal sheets comprising periodic deformations, and a stacking machine configured to stack the expanded metal sheets comprising periodic deformations to form the structured cross-channel packing element. The sheet storage unit is configured to release the first expanded metal sheets directly to the forming machine.
