Stw .: Combination filter-glass fiber disc attachment method Hauni file 1170 Method and device for manufacturing filter cigarettes * with combination filters The invention relates to a method for producing B terzigaretten with a Combination filter consisting of a filter plug of a first filter material and a thin disc, especially made of a relatively soft, fibrous second Filter material, between a final filter plug and the cigarette.

The invention also relates to an apparatus for producing Filter cigarettes with a combination filter consisting of a filter stopper a first filter material and a thin disc, in particular from relative soft, fibrous second filter material, between an adjoining filter plug and the cigarette, with a continuously drivable first feed conveyor with receptacles for cigarettes, with a continuously drivable second feed conveyor with receptacles for Filter plug, with a continuously drivable third feed conveyor for connecting sheets, with a continuously drivable fourth feed conveyor for filter discs and one continuously driven association conveyor with receptacles for one cigarette each, a filter plug and a filter disc and means for enveloping this group with a connecting plate.

There are already numerous embodiments in the cigarette industry of combination filters to reduce nicotine and / or harmful components of tobacco smoke known, in which a combination of two types of filter increases Filter effect is to be achieved. They are combinations of acetate filter plugs with granules (e.g. activated charcoal) and acetate filter stoppers with activated charcoal as effective Filter plugs containing filter material known0 in recent times Stw .: Combination filter-glass fiber disc attachment method Bergedorf, July 22, 1971 - Hauni file 1170 stated the use of relatively thin discs made of fibrous material, e.g. made of glass fibers, with or without chemical additives as a filter in conjunction with Conventional filter plugs, e.g. made of acetate threads, have been tried and tested. Such discs proved to be surprisingly advantageous in terms of their absorption capacity, however, they cater for the machining of filter rods, in particular with the high production speeds required today, there are certainly @ problems because of their short length compared to their diameter and their softness and sensitivity to mechanical stress are difficult to handle.

The invention is based on the problem of trouble-free manufacture of filter cigarettes with combination filters that have at least one filter disc have as a component, in the preparation process even at high speeds enable.

According to the invention, this object is achieved in that cigarettes and filter plugs brought together in groups and aligned axially with one another with a gap formed between the final filter plug and the cigarette is that the groups thus formed are conveyed transversely axially that each insert a filter disc in the space between the cigarette and the final filter plug is promoted and that cigarette, filter plugs and filter discs see during their Further conveyance wrapped in a connecting leaflet and connected to one another will.

The conveyance of the filter disc throws in especially because of this so big a problem because the disc is so thin and therefore not on the circumferential surface just like the cigarettes and filter plugs, can be held. This shows also that it is not on known machines for the production of filter cigarettes such a filter disc is possible Stw .: Combination filter-glass-laser disk An9etzverfahren Bergedorf, July 22, 1971 - Hauni file 1170 between final To promote filter plugs and cigarettes as it is previously only known the filter components and to hold the cigarette for the wrapping process on part of the circumferential surface, According to a further embodiment of the invention, the filter discs are during their promotion in the gaps between in the final stopper and the cigarette held by their faces.

As long as the filter pane has not yet passed through the glued connecting sheet is held in such a way that it cannot shift, it must be supported.
