摘要：The material exchange column contains a packing which can be installed in thehorizontal position of the column. The column has a ring gap between the packing andthe column wall in which collars are arranged. The latter each comprise a band-shaped

region () which lies in contact with the packing. At the upper edge of the band-shapedcollar regions there adjoin spring-elastically connected surface pieces which produce abridge to the wall and which are provided for a return conduction of the liquid from thewall to the packing during the operation of the column. It applies at least for some of thecollars that the latter have elevations in their band-shaped regions which hold the ringgap open in a form-stable manner under the load of the packing when the column lieshorizontally.
