GERARD WENZESLAUS VON NAWROCKI, of the Firm of J. Brandt and G. W. von
Nawrocki, Civil Engineers and Patent Agents, of No. 2, Koch Strasse, Berlin, in
the German Empire. "AN IMPROVED MANUFACTURE OF CIGARETTES AND THE
MEANS OR APPLIANCES EMPLOYED THEREfor." A communication by Louis
Grosskopf, of Koënigsberg, Prussia.
Cigarettes as at present manufactured consist of finely cut tobacco enveloped
either in a piece of thin paper or in a tobacco leaf. If paper is employed the
burning thereof imparts an unpleasant odour to the tobacco, while the envelope of
tobacco leaf is too fragile to afford the necessary strength against fracture to the
cigarette unless it be made of two or more thicknesses, in which case it destroys the
characteristic feature of the cigarette, as distinguished from a cigar.
Now according to the present Invention the necessary strength is imparted to a
cigarette having a single envelope of tobacco leaf in the following manner :-After
the cut tobacco has been enveloped in the leaf and cut to the required length it is
surrounded, while still moist, by a number of pieces of the "aira flexura" or
"waved hair grass," or of esparto grass, or other suitable long thin pieces of material,
and in that condition the cigarette is subjected to pressure and dried either with or
without the application of artificial heat. By this means the envelope of the
cigarette is pressed firmly against the tobacco inside, and has at the same time a
corrugated or ribbed form imparted to it, whereby its strength is greatly increased,

page_text: For conveniently carrying out the above described operation, a number of the
roughly prepared cigarettes are placed, together with a quantity of the "aira
flexuosa" in an open wrapper of canvas or other strong material, which for con-
veniently receiving the cigarettes is first laid against the inside of a small trough.
Care having been taken that each cigarette is surrounded by some of the "aira
flexuosa," the wrapper is wrapped tightly round the bundle thus formed which is
made to assume a cylindrical shape, and pressure is then applied by means of one
or more straps strapped tightly round the bundle. In this condition the cigarettes
are dried, which operation is accelerated on account of the tubular form of the “aira
flexuosa" allowing the passage of currents of air through them in close contiguity to
each cigarette.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Gerard Wenzeslaus von Nawrocki in the Great Seal Patent Office

kopf, of Koenigsberg, Prussia.
Cigarettes as at present manufactured consist of finely cut tobacco enveloped
either in a piece of thin paper or in a tobacco leaf. If paper is employed the
burning thereof imparts an unpleasant odour to the tobacco, while the envelope of
tobacco leaf is too fragile to afford the necessary strength against fracture to the
cigarette unless it be made of two or more thicknesses, in which case it destroys the
characteristic feature of the cigarette, as distinguished from a cigar.
Now according to the present Invention the necessary strength is imparted to a
cigarette having a single envelope of tobacco leaf in the following manner :-After
the cut tobacco has been enveloped in the leaf and cut to the required length it is
surrounded, while still moist, by a number of pieces of, the "aira flexuosa" or
"waved hair grass," or of esparto grass or other suitable long thin pieces of material,
and in that condition the cigarette is subjected to pressure and dried, either with or
without the application of artificial heat. By this means the envelope of the
cigarette is pressed firmly against the tobacco inside, and has at the same time a
corrugated or ribbed form imparted to it, whereby its strength is greatly increased.
For conveniently carrying out the above described operation, a number of the
roughly prepared cigarettes are placed together with a quantity of the "aira
flexuosa" in an open wrapper of canvas or other strong material, which for con-
veniently receiving the cigarettes is first laid against the inside of a small trough.
Care have been taken that each cigarette is surrounded by some of the "aira
flexuosa," the wrapper is wrapped tightly round the bundle thus formed, which is
made to assume a cylindrical shape, and pressure is then applied by means of one or
more straps strapped tightly round the bundle. In this condition the cigarettes are
dried, which operation is accelerated on account of the tubular form of the "aira
flexuosa" allowing the passage of currents of air through them in close contiguity.to
each cigarette:
DESCRIPTION OF THE DRAWINGS.
Fig. 1 shews a side view, Fig. 2 a longitudinal section, and Fig. 3 a cross section
of the before-described improved cigarette.
.
Figs. 4, 5 and 6 shew the means employed for treating the cigarettes in the
manner described.
The cigarettes being formed with an envelope a consisting of a single tobacco leaf
are placed whilst in a moist condition in a strong open wrapper 6 laid in the trough c,

page_text: a quantity of "aira flexuosa" being placed togetherwith the cigarettes so as to
surround each one, as shewn at d, Fig. 4. The wrapper is then closed tightly round
the cigarettes and secured by straps forming a cylindrical bundle, as shewn at Fig. 6.
The pressure thus exerted by the wrapper and straps upon the cigarettes and sur-
rounding aira flexuosa causes the latter to be pressed into the sides of the former to
a certain extent, thus causing the envelope of the cigarette to be pressed firmly
against the tobacco inside and to assume the ribbed appearance shewn, whereby its
strength is greatly increased. In this condition the bundle is subjected to heat or
to a current of air, whereby the cigarettes are dried, so as to retain the shape
imparted to them, such drying being facilitated by the tubular form of the aira
flexuosa permitting the passage of the air through them in close contiguity to each
cigarette.
Having thus described the nature of the said Invention, I claim,-
First. The before-described improved manufacture of cigarettes having a single
tobacco leaf envelope by surrounding them with aira flexuosa or other long thin
pieces of material and subjecting them to pressure, so as to press the envelope
closely against the tobacco inside and impart to it a ribbed form.
Second. The use of the aira flexuosa for preparing cigarettes in the manner set
forth in the preceding claim, substantially as herein described.
In witness whereof, I, the said Gerard Wenzeslaus von Nawrocki, have here-
unto set my hand this Twentieth day of June, in the year of our Lord One
thousand eight hundred and seventy-seven.
