Method and device for manufacturing from

Filter cigarettes

The invention relates to a method and a device for the production of filter cigarettes

In the manufacture of filter cigarettes, it has been customary to a piece of the cigarette rod with a filter material β assemble Tück and the two parts characterized su interconnect _t that their abutting ends a strip of sheet material commonly referred to as Mundstüoknaterial is herumgewiokelt. Before being wrapped around the cigarette unit, this mouthpiece material is coated with a liquid solvent which, after the connection has been completed, is solidified by drying. However, when handling the mouthpiece material coated with the liquid solvent, spillage of the solvent sometimes occurs, so that the machine must be temporarily shut down to remove the spilled solvent.

For several years, certain heat-activated or heat-bondable bindings - bj & w. Adhesives available that are dry at construction temperature, but can be made tacky ^{by heating to around 66-93 0 C.} These adhesives have so far not been used for the production of ton filter cigarettes, since the conventional machines are not laid out for the heating of the Elebolttele and for the subsequent cooling of the adhesive. In addition, when using such a debmlttele, the bond is not firm before the adhesive has cooled down. Because of this, the bond prevents a tendency to open after the first application, so that the finished cigarette is defective.

There are difficulties in manufacturing of filter cigarettes from a cigarette unit, consisting of a Zlgarettenstrangstück and a filter piece, one end of which at one end of the cigarette rod by wrapping a piece of strip of material and joining it to each other Linden, according to the invention thereby eliminate that on one side of the cigarette unit heated with a heat-activatable adhesive Piece of strip material is attached, in-

the initially a coated edge area of the harvested Strip material pieces are brought into contact with the cigarette unit in such a way that they end together Spanned strand ends, and at least this edge area cooled to solidify the adhesive

According to the invention, heat-activatable adhesives are becoming old coated strips of mouthpiece material used. The difficulties encountered in the conventional methods are eliminated by the fact that next one edge of the heated adhesive strip a cigarette coated with a filter stick is pinned, this pinning is omitted, without the immediate rolling of the cigarette and wrapping the same is aimed at in the mouthpiece material, rather the cigarette then runs slowly an unheated trajectory of such a length that the adhesive cools down and calibrates the initial bonding can solidify. The cigarette is then twisted so far that the initial stapling is in an angular position is spent, in which it is inconsistent with a heating shoe, which is then with the cigarette comes into contact and is able to roll over several revolutions, whereby the adhesive is heated and over
