Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for manufacturing a tobacco product which, after application of glue, is divided into pieces of a bonding strip that is wrapped around the tobacco product and its associated mouthpiece. A pattern of glue on a bonding strip that can move at different speeds for different purposes - this glue pattern runs in the direction of transport of the bonding strip and transversely to this; By means of a transmission means, the fragment of the joining stripe consists of a strip of glue applied over the joining stripe so that it has one stripe of glue on each of its four edges. Regarding the method.

The invention further provides a conveying means for withdrawing the bonding stripes from the stock, a stock of glue, and a pattern of glue in the form of stripes of glue whose surface runs in the direction of rotation and transversely thereto. A rotary glue conveyor roller is made, as well as the pieces of the bonding strip which are wound around the tobacco product and the associated mouthpiece in each case on a rearwardly arranged roller device. A pattern of glue on a bonding strip capable of moving at different speeds for tobacco products, with a subsequent cutting device for cutting from the stripe; It consists of stripes of glue running horizontally and horizontally.

A hole in the mouthpiece area to allow the smoker to draw in additional fresh air through the hole or porous material, which mixes with the tobacco smoke and acts to dilute and cool the tobacco smoke. BACKGROUND OF THE INVENTION It is known to coat tobacco products, in particular tobacco products with a tip, such as filtered cigarettes, using a coating made of a porous material or a porous material in this part. When manufacturing such tobacco products, care must be taken to ensure that the air holes in the covering material are not glued together when the tip and tobacco rod are wrapped and glued with pieces of the binding strip. For this purpose, glue is applied in the form of stripes only to the edges of the combined stripe fragments. For this purpose, the glue applicator roller and/or glue transfer roller has a recess for the pattern of glue on the device for applying glue onto the bonding stripe, the dimensions of this recess being equal to the size of the bonding stripe. corresponds to the pattern of glue to be applied on top. At this time, synchronization is maintained because the circumferential speed of the glue transfer roller corresponds exactly to the transport speed of the bonded stripe. Since the length of the bonding stripe piece to be cut from the bonding stripe depends on the diameter of the tobacco rod and tip to be bonded, the glue applicator roller and glue transfer roller are used when changing the size. The gears that drive these rollers must also be replaced with a different diameter and a different glue pattern. A change in size therefore requires, in the case of known devices, considerable retooling and a considerable stock of glue rollers and gears.

The present invention provides a glue application method of the kind mentioned at the outset, in which different patterns of glue can be applied, such that changes in size can be carried out with a minimum amount of work and replacement parts. The purpose is to consider the possibilities.

This object is achieved according to the invention as follows. That is, as a result of said bonding stripes being moved at different speeds with respect to the circumferential speed of the transfer means,
This bonding stripe performs a wiping motion on the transfer means, and the distance between the glue stripes running transversely to the conveyance direction on the transfer means causes a speed difference between the bonding stripe and the transfer means. is solved by increasing or decreasing the desired spacing of the glue stripes above the bonding stripes in inverse proportion to the desired spacing.

In order to carry out the above-mentioned method, the apparatus mentioned at the outset has the following features: the conveying means for drawing out the bonded stripes can be driven at a speed different from the circumferential speed of the glue conveying roller; The spacing of the glue stripes running transversely to the conveying direction above is inversely proportional to the speed difference between the conveying means and the glue conveying rollers and is greater than or equal to the desired spacing of the glue stripes above the bonding stripes. It is characterized by becoming smaller.

Therefore, when changing the size, in order to cut longer or shorter bonding strip pieces from the corresponding suitable glue pattern, simply cut the corresponding smaller or larger glue pattern. It is only necessary to install a separate glue conveyor roller attached thereto and to vary the speed of the conveying means for conveying the bonded stripe via the glue conveyor roller to the cutting device in accordance with the desired length of the pieces of the bonded stripe. .

The construction and operation of the filter-applying machine known per se, which is shown in FIG. Transfer to stepped drum 2. This stepped drum eliminates the misalignment of the cigarettes that have been sent in a slightly shifted manner, and delivers them to the assembly drum 3 in two-by-two rows with an intermediate interval between the cigarettes.
A suction port in the form of a filter rod reaches from the magazine 4 onto the cutting drum 6 and cuts two circular cutters 7.
The filter plugs are cut into filter plugs with a length twice the length to be used, are shifted little by little on a stepped drum 8, and are arranged into rows of plugs arranged one behind the other by a slide drum 9, The cigarettes are inserted by the accelerating drum 11 onto the assembly drum 3 into the intermediate spaces of the rows of cigarettes. Cigarette = Filter =
The groups of cigarettes are pressed together and axially closely spaced. This group is then received by the transfer drum 12. The bonding strip 13 is drawn out of the stock in the form of a web 14 by means of conveying means in the form of a pull-off roller 16 and a hold-down roller 17. The bonding strip 13 is bent over a sharp edged pre-folder 18;
The glue pattern shown in FIG. 3 is applied by a glue applicator and is applied by a cutter drum 22 over a coating roller 21 on which the bonding stripes slip because it is driven at a higher circumferential speed. It gets cut off. The pieces of the cut bonding strip are pasted onto the group of cigarettes/filters/cigarettes on the transfer drum 12 (see FIG. 4) and rolled by a roll hand 24 on a rolling device in the form of a roll drum 23. The filter is then wrapped around a group of cigarettes, filters, and cigarettes. The resulting group of two filtered cigarettes is sent via a drying drum 26 to a cutting drum 27, where the filter stopper is cut from the center to form individual filtered cigarettes. At the same time, a cigarette with a defective filter is extruded. A reversing device 31 working together with the transfer drum 28 and the collecting drum 29 reverses a row of filtered cigarettes and at the same time passes this row through the transfer drum 28 and the collecting drum 29 to remove the unreversed filtered cigarettes. Send it into the line. Via the inspection drum 32, the filtered cigarettes reach an extrusion drum 33, on which the head of the filtered cigarette is further detected prior to the extrusion process. A take-off drum 36 working together with a brake drum 34 places the filtered cigarettes onto a take-off belt 37.

The glue applicator 19 has a stock container 38 for glue, from which a glue transport roller (bucket roller) 39 takes out a thin film of glue on its circumferential surface. The circumferential surface of the glue conveying roller 39 is carved with polished depressions (glue pattern) in the form of vertical stripes 41a...41d and horizontal stripes 42a, 42b (FIG. 2).

Glue conveyor roller 39 that borders this recess
The smooth circumferential surface of rotates on the smooth circumferential surface of another glue transport roller in the form of a glue transfer roller, thereby creating a longitudinal stripe 41a... on this transfer roller. Only the glue in the horizontal stripes 41d and 42a and 42b are transferred, and the corresponding glue pattern is drawn.

The pull-out roller 16 operates at a different circumferential speed than the glue conveyance roller 39 and the glue transfer roller 43.
In the example taken here, it is driven at a higher circumferential speed. As a result, a combined stripe 13,
A relative movement occurs between the bonding strip 13 and the circumferential surface of the glue transfer roller 43, so that the bonding stripe 13 moves in a wiping manner over the circumferential surface of the rotating glue transfer roller 43. Therefore, the glue pattern 40 on the glue conveying roller 43 is stretched when being transferred onto the bonding stripe 13, so that the glue pattern 40 on the bonding stripe 13 is stretched out on the surface of the glue conveying roller 39. Horizontal stripe 42
Glue stripe 44 wider than a, 42b
horizontal stripes 42a, 42b having lateral stripes 42a, 44b and recessed above the glue conveying roller 39;
Glue-free zones 46a, 46b are created which are longer than the interval A (A').

By cutting from the glued bonding stripe 13 through the horizontal stripes 44a, 44b of the glue pattern, a bonding stripe fragment 47 consisting of two symmetrical pieces 47a, 47b, respectively, is obtained. be cut out. These fragments have glue stripes around all edges 4
4a, 48a, 48c, or 44b, 48b, 4
It has a glue-free zone 46a or 46b surrounded by 8d.

The bonding stripe fragment 47 is attached to the front glue stripe 44a, as shown in FIG.
44b onto the group 51 of cigarettes (Z)=filter plugs (F)=cigarettes (Z) and then wrapped around this group, with the rear glue stripes 44a, 4
4b forms the adhesive line of the bonding stripe fragment 47. The coated cigarette-filter-cigarette group 51 is then cut from the non-glued zone 52a between the glue stripes 48c and 48d.

In the event of a change in size, i.e. if a bonding stripe piece 47 of a different size is required, simply replace the transfer roller 16 with a pull-out roller of a different diameter and the glue transport roller 39 with a different polishing pattern ( All you need to do is replace it with a roller that has a recess. At that time, there is a recess that runs horizontally to the rotation direction of the glue conveyor roller (receiving part of the glue stripe).
In addition, the spacing between these recesses is selected to be larger or smaller than the spacing between the stripes of glue on the bonding stripes and these stripes in inverse proportion to the speed difference between the bonding stripes and the glue conveying roller or glue transfer roller. must be If, as is naturally possible, the circumferential speed of the glue transport roller or glue transfer roller is greater than the transport speed of the bonding strip, the corresponding dimensions will naturally be larger. The principle underlying the present invention is that it does not matter whether the glue pattern is engraved on the glue transport roller, on the glue transfer roller, or on both. It's just a small thing.
