Abstract
The invention concerns a method for producing a cigarette filter unit, in which filter elements are disposed on a porous or perforated covering strip and at least partially wrapped thereby and adhesively joined. The adhesive substance is applied to the covering strip along coating tracks which are at least approximately equidistant from each other and extended at an angle to the longitudinal orientation of the covering strip. The filter strand formed in this manner is subdivided by a cutting device.
