Will be a consequence of cigarette rod filter plug cigarette rod groups arranged transaxially one behind the other as a single-lane material flow too fed to a covering device, so it is a one-lane Filter attachment. In a double-lane filter attachment machine will be two material streams with articles at least promoted a covering device. In particular, at a two-lane filter attachment two covering devices for each provided a stream of material.

From the patent documents DE-C-38 05 753, DE-C-37 96 753 and DE-C-37 06 751 are methods and apparatus for the manufacture of Filter cigarettes from cigarette rods, which are double-stranded be prepared known.

Here, DE-C-38 05 753 shows a method for the production of filter cigarettes made of double-stranded cigarette rods, in the double-length cigarette rods guided double lane become.

DE-C-37 06 751 discloses an apparatus for producing filter cigarettes, for simultaneous double-track processing each two double-length cigarette rods two lining feeders for two tipping paper strips.

DE-C-37 06 753 shows a method and a device for transferring of rod-shaped articles of the tobacco processing industry from a four-row to a double-row formation, the articles be formed in the transverse axial direction.

Further, in European Patent Applications EP-A-895 724 and EP-A-895 725 each discloses methods of making Filtered cigarettes in a filter attachment machine described in which double-length cigarette rods are manufactured double-lane. After cutting the double-length tobacco sticks are the Tobacco sticks simple length continued in a staggered arrangement.

In addition, known from DE-A-196 26 697, a single-row To cut and spread a series of double-length tobacco sticks and place a double-length filter plug between them. The way formed groups are on alternating grooves of a drum an upper and lower Filteransetzvorrichtung supplied in the essentially in the same vertical plane.

Based on this prior art, it is the task of the present Invention, production speed and productivity a, in particular double-lane, Filteransetzmaschine increase, while the effort is kept as low as possible should.

This object is achieved by a method for the production of Filtered cigarettes, with cigarette rods of double length in cigarette rods simple length to be cut between these Double-length filter plug is inserted, this double-length Filter plug with the two cigarette rods of simple length is wrapped by wrapping by means of a tipping paper leaflet and by a subsequent separation cut through the double-long Filter plugs filter cigarettes normal use length arise, which is further developed by the fact that two streams of material with cigarette rod filter plug cigarette rod groups side by side be promoted, the articles of the first material flow be provided with paper tiling and the following articles of the other material stream provided with tipping paper leaflets become.

According to the invention is for each material stream consisting of a Series of cigarettes-rod-filter-plug-filter-rod groups arranged one behind the other transversely each a covering device provided wherein attaching the tipping paper leaflets to the articles the two streams of material takes place successively and the material flows in the area of adhering the tipping paper side by side or promoted in parallel. This will achieve that the transport routes for the tipping paper or tipping paper strips and the transport routes of the material flows themselves do not cross, so in addition to increasing production output also a good accessibility to the articles or intermediates at the filter attachment machine in the area of the padding devices is reached. Compared to a single-lane filter attachment machine will the production capacity at the double lane Filter attachment doubled when two material streams simultaneously at the same conveying speed as the one-lane Filter attachment machine to be transported. Furthermore it makes a simplification that the material flows next to each other be guided, whereby it is not necessary, the material flows to supply in different ways the respective pad means. As a result, the structural complexity of a filter attachment machine reduced because the two material streams on the same Conveying means, i. Carrier drums, be promoted.

Preferably, the articles of material flows, preferably alternately conveyed offset to one another, so that, for example on a conveyor drum between two in a row longitudinally arranged articles of a material flow an article the other material flow is arranged longitudinally axially offset. Here, in the grooves of the conveying drum alternately the Article of the two streams of material conveyed side by side.

In order to obtain two streams of material, the articles of material flows formed from articles of a stream of starting material. When Starting material stream, for example, tobacco rods become double Length of a single-lane cigarette rod machine to the Transfer filter attachment. For this single-lane feedstock stream be after execution of appropriate procedures Cigarette rod-filter plug-cigarette rod groups formed as intermediates in a subsequent step be divided into two material streams.

In particular, the material flows by spreading the article the feedstock stream e.g. formed on a spreading drum. Here, the articles are pulled apart longitudinally.

In order to further increase the production output of the filter attachment machine, The distances of the articles of each flow of material will prevail Attachment of tipping paper leaves shortened, allowing more items arranged with reduced pitch on a conveyor drum become. Thus, at a constant machine speed the production speed of the filter attachment machine increased. To ensure secure attachment of the tipping paper To ensure the articles should have the transverse axial distance between two cross-axially spaced articles of a material flow larger than the length of the tipping paper leaflets to be attached.

According to an advantageous alternative embodiment of the invention It is suggested that the distances of the articles of the output current be shortened. Before from the source material stream two streams of material are created, the transverse axial distances the article or intermediates of the feedstock stream reduced. As the source material flow in two streams of material is split, the Queraxialen distances between the articles of the source stream are less than the length the adhered tipping paper leaflets, since the attachment of tipping paper leaflets only after the distribution of the source material stream takes place in two material streams.

In addition, in a preferred embodiment of the invention suggested that after the shortening of the distance the Filter plug between two longitudinally spaced cigarette rods be inserted.

In particular, the tipping paper leaflets around the articles of the wrapped around the first stream of material before the tipping paper leaflets for the second material flow to the articles of the second material flow be attached. This will ensure a safe wrapping reached the article of the first material flow.

Further, it is preferable that the articles of the material streams after the wrapping with the respective tipping paper leaflets to a Material stream are combined so that the produced cigarette rod filter plug cigarette rod groups both material flows on a cutting device on a conveyor drum to filter cigarettes normal length of use.

Moreover, it is particularly favorable when the articles of the first and second material flow with a larger transverse axial distance promoted between the articles as the articles of output current become.

Another solution to the problem is a filter attachment machine in that in each case a covering device for at least two material streams with cigarette rod filter plug cigarette rod groups are provided, wherein the padding devices in the conveying direction the side by side conveyed material flows one behind the other are arranged.

Preferably, means for parallel guiding the material streams, especially in the area of the covering devices. such Guide means are, for example, double-wide conveyor drums compared to conveyor drums on a single-lane filter attachment machine.

Furthermore, means for forming the material streams of a Provided starting material flow, so that twice long tobacco sticks from a cigarette rod maker to the filter attachment machine be handed over. This ensures that, for example a heavy-duty cigarette machine with a double lane Filter attachment can be combined. It is not necessary, a double-strand machine of a double-lane filter attachment machine upstream.

A power increase is further achieved when means for shortening the transverse axial distance of the articles of the source material stream and / or the material streams are provided.

In an advantageous embodiment of the invention are at the Filteransetzmaschine Means for wrapping the articles of material flows provided with the tipping paper leaflets.

In the following figures are the same or similar elements or corresponding parts provided with the same reference numerals, so apart from a corresponding renewed idea becomes.

In Fig. 1 is a schematic view of a doppelbahnigen Filteransetzmaschine 10 is shown. The schematic functional sequence is shown in Fig. 2.

The filter attachment machine 10 receives double-length tobacco rods 15 from a cigarette rod machine, not shown here. For this be by means of a transfer drum 11, the tobacco sticks 15 of taken over the cigarette rod machine and a conveyor drum Pass 12 to a conveyor drum 13.

During their promotion on the conveyor drums 12, 13 are shortens the Queraxialen distances of the tobacco sticks 15, wherein at the transfer of the tobacco sticks 15 from the conveyor drum 13 to the Conveying drum 14, the distances of the tobacco sticks 15 in comparison to the intervals of the tobacco sticks 15 halved on the conveyor drum 11 are. Shortening of cross-axial distances of articles 15 is also referred to as pitch reduction or deceleration.

On the conveyor drum 14, the double-length tobacco sticks 15 cut in the middle to tobacco sticks 115 simple length and delivered to a spreading drum 21 having a longitudinal axial Distance between the longitudinally aligned tobacco rods 115 simple length caused by spreading the Article 15.

Subsequently, the spread tobacco sticks 115 become easier Length of the conveyor drum 21 to a compilation drum 22nd to hand over. Next is an insert drum 24 for filter plug 25th (FIG. 2) twice the length of use on the assembly drum 22 arranged so that in each case between two longitudinally axially spaced Tobacco sticks 115 a double-length filter plug 25 of the Insertion drum 24 is inserted. The loading drum 24 receives Filter plug 25 double working length from a filter feeder 100, which has two offset filter magazines 110, 120 features. In the European patent application with the Reference 03005286.4 is a filter feed device on a filter attachment of two offset from each other Filter magazines described and is fully in the present patent application was included.

After assembling the cigarette rod filter plug cigarette rod groups on the compilation drum 22 are the group article passed to a spreading drum 23, wherein every second Article of successively arranged articles each a mass flow M1, M2 is allocated. This arise from the one-lane Starting material flow with the succession and cross-axial arranged cigarette rod filter plug cigarette rod groups the two mass flows M1, M2. For this purpose, the spreading drum 23 and all other conveyor drums formed about twice as wide like the conveyor drums for the one-lane feedstock stream from the transfer drum 11 to the assembly drum 22nd

In an alternative, not shown here are of a cigarette rod machine two mass flows to the filter attachment machine to hand over.

After splitting the feedstock stream into two streams of material M1, M2 are the two material streams M1, M2 to a Passing conveyor drum 31, wherein on this conveyor drum 31st the articles of the two streams of material parallel and next to each other be transported. Here, the Queraxialen distances between the articles of each material flow M1, M2 twice as large like the distances of the finished assembled article groups the compilation drum 22. By the longitudinal axial spread of the Article on the spreading drum 23 becomes a sufficient cross-axial Distance between the articles of each material flow M1, M2 created, so that tipping paper sheets to the individual cigarette rod filter plug cigarette rod groups be securely attached without a tipping paper leaflet touches a second article group.

An alternative to longitudinal axial spreading and pulling apart the material flows can also by means of a turning device with e.g. two turning or conical drums are realized.

On the conveyor drum 31, the articles of the two mass flows M1, M2 alternately in the receptacles or grooves of the conveyor drum 31 arranged. From the conveyor drum 31, the article the two mass flows M1, M2 to a conveyor drum 32nd indicated, so that from a coating apparatus 50 toffing paper leaflet 55 (FIG. 2) to the articles of the first mass flow M1 be attached. After the transfer of the two mass flows M1, M2 to the conveyor drum 33 are the articles of the first Mass flow M1 from the attached tipping paper leaflet 55 wrapped while the parallel sponsored article of the second Mass flow M2 still have received no tipping paper leaflet.

After further transport of the two mass flows M1, M2, the Article of the second mass flow M2 on a conveyor drum 34 from a second pad 60 each with a tipping paper leaflet 65 (FIG. 2).

Subsequently, the articles of the second mass flow M2 are completed wrapped by the tipping paper leaflets 65, while the Article of the first material stream M1 parallel to the articles of the second material flow M2 on the same conveyor drums 34, 35th be transported.

After wrapping the articles of both mass flows M1, M2 be on a conveyor drum 36, the two mass flows through longitudinal axial telescoping joined together to form a sequence, so the one-lane series of wrapped cigarette rod filter plug cigarette rod groups on a cutting drum 41 cut in the middle of the double-length filter plug, so that filter cigarettes 225 simple use length (Fig. 2) arise. Following the cutting drum 41 are the cut Article 225 pulled apart on a spreading drum 42 and on subsequent conveying commons 43, 44 testing equipment for the filter cigarettes 225 delivered.
