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.

Cigarette filter units

Production of cigarette filter units

The invention concerns a method for producing a filter cigarette with a filter unit which is provided with a porous or perforated covering strip. A porous or perforated connecting strip joins the tobacco part to the filter unit. The adhesive for connecting the covering strip to the outside of the filter element on the one hand and the adhesive for connecting the connecting strip to the outsides of the filter unit and of the tobacco part on the other hand is applied on those surfaces on the one hand of the covering strip and on the other hand of the connecting strip which are inwardly oriented on the filter cigarette. The adhesive is applied on coating tracks on the sheating strip and on the connecting strip, which said tracks extend so that for any given relative displacement between the said two strips in the longitudinal direction of the filter unit the adhesive coating tracks on the covering strip and on the connecting strip on the other hand always intersect at an angle or at right angles in the radial direction with respect to the longitudinal axis of the filter unit.

Method for producing filter cigarettes

Cigarette filter units are made in a long strip with alternate portions of fibrous and pourable filter material. The fibrous portions are first attached at spaced intervals to a sheathing strip which is wrapped practically right around them to form a cylinder with regular empty spaces between the fibrous portions and openings into the spaces. In a special unit, air is extracted from these spaces so that when the spaces enter a chamber containing pourable filter material, they suck the material in to fully fill the spaces. Excess filter material is brushed off the filter unit, and a sealing strip is stuck over the openings.
