The material exchange column (1) contain; a packing (2) which can be installed in the horizontal position of the column. The column has a ring gap (12) between the packing and the column wall (10) in which collars (3) are arranged. The latter each comprise a band shaped region (30) which lies in contact with the packing. At the upper edge of the band-shaped collar regions there adjoin spring-elastically connected surface pieces (31) which produce a bridge to the wall (10) and which are provided for a return conduction of the liquid from the wall to the packing during the operation of the column. It applies at least for some of the collars that the latter have elevations (4) in their band shaped regions which hold the ring gap open in a form-stable manner under the load of the packing when the column lies horizontally.

Colonne (1) échangeuse de matière renfermant : un garnissage (2) pouvant être installé à l'horizontale dans la colonne. La colonne comporte un espace annulaire (12) entre le garnissage et sa paroi (10) dans lequel des colliers (3) sont disposés. Chaque collier possède une région en forme de bande (30) qui est en contact avec le garnissage. Au bord supérieur des régions des colliers en forme de bande se trouvent, placées de manière contiguë, des pièces (31) de surface reliées élastiquement et comprimées par un ressort, lesquelles forment un pont vers la paroi (10) et qui sont conçues pour la conduction de retour du liquide à partir de la paroi jusqu'au garnissage pendant le fonctionnement de la colonne. Cela s'applique au moins à quelques-uns des colliers comportant des élévations (4) dans leurs régions en forme de bande, qui maintiennent ouvert l'espace annulaire de façon stable sur le plan de la forme sous la charge du garnissage lorsque la colonne est à l'horizontale.
