Improvement in the Manufacture of Cigarettes.
I, OSCAR HEILMANN, of Pragerstrasse 2, Dresden, Kingdom of Saxony, German
Empire, Merchant, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
This invention consists in an improvement in the manufacture of cigarettes
provided with hollow mouthpieces.
According thereto such cigarettes are manufactured by an improved process in
which hollow mouth-piece portions and tobacco fillings, each of double the length
necessary for a single cigarette, alternate in a continuous roll or rope (hereinafter
called a rope) and are both cut in the centre of their length, in order to form
cigarettes. The hollow mouth-piece which may be made of any suitable substance,
as paper, are of cylindrical form and contain no tobacco; but they may contain
paper strips curled into spirals or other such devices for preventing tobacco from
the filling from entering the smoker's mouth. The process is intended to obviate
defective cuts in dividing the rope into proper cigarette lengths, such defective
cuts being illustrated in Figs. 1 and 2 of the accompanying drawings. Fig. 1
shows a defective cut leaving a small portion of the mouth piece on the tobacco
end of the next cigarette, while Fig. 2 shows a cut leaving a small portion of the
tobacco filling in the mouthpiece of the next cigarette, and Fig. 3 shows the
correct manner of dividing the mouth piece of one cigarette from the filling of
the next cigarette.
It is very difficult to divide in the manner shown in Fig. 3 a continuous rope
containing alternately a hollow mouth-piece and a tobacco filling of the proper
length to constitute one cigarette.
Now according to this invention the manufacture of cigarettes with hollow
mouth-pieces is performed in such a way, that the continuous rope comprises, as
shown in Fig. 4, hollow mouth-piece portions of twice the length necessary for
a single cigarette, and the adjacent tobacco-fillings are also of twice the length
required for a single cigarette.
Hollow mouth-piece portions a, and tobacco fillings b, each of double the length
necessary for a single cigarette, are placed alternately in and moved along a form-
ing channel, in which travels an endless paper strip used as a wrapper, which is
folded and secured around the mouth pieces and tobacco filling as they move along
the forming channel.
The dividing of the rope takes place as shown in Fig. 5 in the middle of each
hollow mouth-piece portion of double length and also in the middle of each double-
length of tobacco-filling; small deviations of the cuts from the exact middle lines
are of no consequence and do no harm, because the resulting cigarettes will all be
of approximately equal length without showing defects of the kind illustrated
in Figs. 1 and 2.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is ―
110c0ee
for manufacturing cigarettes with hollow mouth-pieces, consisting

page_text: in forming ropes composed of a series of tobacco fillings and of hollow mouth-
piece portions, both of twice the length required for one cigarette, and dividing
or cutting the rope in the middle of each hollow mouth-piece portion and in the
middle of each tobacco filling.
