Abstract

A method and arrangement are provided for producing compound filters for products in the tobacco-processing industry. A filter tube, having a filter element in a central region of the filter tube, is supplied to a predetermined position. Predetermined portions of filtering material are then inserted into the filter tube from at least a first end of the filter tube so that filter segments form in at least a first part of the filter tube.
