Improvements in the Manufacture of Cigarettes and Means
therefor.
I, WILLIAM LLOYD WISE of No. 46 Lincolns Inn Fields, in the County of
Middlesex, Consulting Engineer and Patent Agent, do hereby declare the nature of
the said invention (a communication to me from abroad by Heinrich Franz Riedel
of Dresden in the Kingdom of Saxony Empire of Germany) to be as follows :-
This invention relates to an improved method of and means for manufacturing
cigarettes according to which invention cigarettes are provided with wrappers formed
of tobacco leaf and such tobacco leaf wrappers are formed by the aid of an expansible
compound core having an elastic surface and by the employment of a tight wrapper
placed around the tobacco leaf wrapper during the drying and during the filling
process.
Thus according to this invention a wrapper of tobacco leaf is substituted for the
usual paper wrapper of cigarettes.
It is to be understood, that for manufacturing such wrappers of tobacco leaf only
that part of the leaf of tobacco is to be used, which is free from coarse ribs,
especially when the outer appearance of such tobacco wrapper is desired to be even
and smooth.
For this purpose only those parts of the tobacco leaf which are free from the
coarser ribs are selected. They are cut out, moistened, brought to proper size, spread
out or flattened and are provided with the usual gum, binding material or cement
either at one edge, or, if the wrapper is to be applied in the manner of a cigar wrapper
at one end or corner. The piece of leaf thus prepared may be rolled and gummed, to
form a cylinder for the reception of the cigarette tobacco.
The formation or manufacture of such wrapper or cylinder from tobacco leaf must
however be accomplished very carefully in view of the fineness of the material
especially if the outer appearance is desired to be smooth and even.
To accomplish this according to this invention there is employed the manufacture of
the tobacco leaf wrappers an expansible compound core or mandril which may be
.מ

page_text: easily removed from the formed wrapper. It is preferred to use a core of elastic
surface which permits all uneveness of the tobacco leaf to protrude towards the
inside of the wrapper, when external pressure is applied to the latter.
The core or mandril it is preferred to use consists mainly of a piece of india
rubber pipe of a diameter rather less the diameter of the cigarette to be produced.
It is not however a matter of necessity, that the core must be of an elastic substance
like india-rubber though it is preferred to use such elastic substance for the purpose.
Into this pipe is inserted a metal tube baving either one or two longitudinal splits or
cuts. If there are two splits or cuts the tube will form two halves. Into this split
tube a small metal spindle or rod is inserted, which rod or spindle must be of such
diameter, as to slightly expand the split tube and the elastic pipe. When the split
tube is inserted into the elastic pipe, and the metal rod or spindle into the split tube,
the elastic pipe will be expanded so that its outer diameter corresponds with the inner
diameter of the wrapper to be manufactured. The piece of prepared leaf is now
rolled around the compound core or mandril and the edge or end of the said piece of
leaf is fastened by the cement.
The india rubber core will offer for the rolling of the piece of tobacco leaf, a soft,
elastic bed, facilitating easy and exact work.
After the gumming or cementing of the wrapper the same is, while it is yet on its
compound core, rolled up in a piece of paper, which must be strong and smooth and
cut to a suitable size, but it must not be too thick. The compound core, with the
tobacco wrapper and the paper wrapper are then put aside to dry. It is preferred to
wrap the piece of paper around the tobacco wrapper very tightly, so that all uneveness
of the tobacco wrapper is pressed into the elastic surface of the core, so that the
tobacco wrapper may become smooth and even on the outside.
After a certain period for the drying of the gum within the tobacco wrapper and
for the smooth formation of the outside of said wrapper the metal rod or spindle is
withdrawn, then the split tube with the india rubber pipe, which will be again con-
tracted to its normal diameter by the removal of the metal tube and the rod or spindle.
A slight stretching lengthwise may also be given so that by this operation it may be
easily removed from the tobacco wrapper, which is still confined in its paper wrapper.
It is still left within this paper wrapper whilst it is being filled with tobacco in order
to avoid any undue pressure or disfiguration of the tobacco wrapper in handling and
filling the same. When this filling is completed the paper wrapper-which may be
used repeatedly is unfolded. The cigarette is then complete or it may be provided
with a mouthpiece etc.

I, WILLIAM LLOYD WISE, of No. 46, Lincolns Inn Fields, in the County of
Middlesex, Consulting Engineer and Patent Agent, do hereby declare the nature of
this invention (a communication to me from abroad by Heinrich Franz Riedel
of Dresden in the Kingdom of Saxony, Empire of Germany) 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 relates to an improved method of and means for manufacturing
cigarettes according to which invention cigarettes are provided with wrappers formed
of tobacco leaf and such tobacco leaf wrappers are formed by the aid of an expansible
compound core having an elastic surface and by the employment of a light wrapper
placed around the tobacco leaf wrapper during the drying and during the filling process.
Thus according to this invention a wrapper of tobacco leaf is substituted for the
usual paper wrapper of cigarettes. It is to be understood that for manufacturing
such wrappers of tobacco leaf only those parts of the tobacco leaf are to be used
which are free from coarse ribs, especially when the outer appearance of such tobacco
wrapper is desired to be even and smooth. They are cut out, moistened, brought to
proper size, spread out or flattened and are provided with the usual gum binding
material or cement either at one edge, or, if the wrapper is to be applied in the
manner of a cigar wrapper, at one end or corner. The tobacco leaf thus prepared
may be rolled and gummed to form a cylinder for the reception of the cigarette
tobacco.
The formation or manufacture of such wrappers or cylinders from tobacco leaf
must however be accomplished very carefully in view of the fineness of the material
especially if the outer appearance is desired to be smooth and even.
To accomplish this according to this invention there is employed for the manu-
facture of the tobacco leaf wrapper, an expansible compound core or mandril which
may be easily removed from the formed wrapper. It is preferred to use a core
of elastic surface which permits unevenness of the tobacco leaf to protrude towards the
inside of the wrapper when external pressure is applied to the latter.
Fig. 1 illustrates in longitudinal section an arrangement of core or mandril
according to this invention. Fig. 2 is a cross section.
The core or mandril it is preferred to use consists essentially of a piece of india
rubber pipe A of a diameter equal to the diameter of the cigarette to be produced. It
is not however a matter of necessity that the core must be of an elastic substance like
india rubber though it is preferred to use such elastic substance for the purpose.
Into the pipe A is inserted a metal tube B having a longitudinal split or cut at one
side. Into this split tube a small metal spindle rod or tube D is inserted which rod
spindle or tube D must be of such diameter as to slightly expand the split tube and
the elastic pipe. When the split tube B is inserted into the elastic pipe and the metal
rod spindle or tube D into the split tube B, the elastic pipe A will be expanded
so that its outer diameter corresponds with the inner diameter of the wrapper
to be manufactured. The piece of prepared leaf is now rolled around the compound

page_text: core or mandril and the edge or end of the said piece of leaf is fastened by the
cement. The india rubber core will offer for the rolling of the piece of tobacco leaf,
a soft, elastic bed facilitating easy and exact work.
After the gumming or cementing of the wrapper the same is, while it is yet on its
compound core, rolled up in a piece of paper which must be strong and smooth and
cut to a suitable size, but it must not be too thick. The compound core, with
the tobacco wrapper and the paper wrapper are then put aside to dry. It is preferred
to wrap the piece of paper around the tobacco wrapper very tightly so that all
unevenness of the tobacco wrapper is pressed into the elastic surface of the core
so that the tobacco wrapper may become smooth and even on the outside.
After a certain period for the drying of the gum within the tobacco wrapper and
for the smooth formation of the outside of said wrapper the metal rod, spindle
or tube D is withdrawn, then the split tube B with the india rubber pipe A which will
have become again contracted to its normal diameter on the removal of the rod,
spindle or tube D. It will be understood that this rod or spindle may be hollow
or solid, the essential point being that its diameter is such so as to cause expansion or
contraction of the india rubber pipe, when the central spindle or rod is inserted and
withdrawn respectively. A slight stretching lengthwise may also be given so that by
this operation it may be easily removed from the tobacco wrapper which is still
confined in its paper wrapper. It is still left within this paper wrapper whilst it is
being filled with tobacco in order to avoid any undue pressure or disfiguration of
the tobacco wrapper in handling and filling the same. When this filling is completed,
the paper wrapper-which may be used repeatedly-is unfolded. The cigarette is
then complete or it may be provided with a mouthpiece etc.
Fig. 3 illustrates in longitudinal section and Fig. 4 in cross section a modification
wherein the tube B is split at both sides thus forming two halves. As in the arrange-
ment shewn in Figs. 1 and 2 the central piece D may be in the form of a tube or may
be a solid rod or spindle constructed of suitable material such as metal or wood.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what
I claim is,
1. The method, substantially as described, of forming cigarette wrappers from tobacco
leaf by the use of an expansible and contractible core or mandril.
2. In the manufacture of cigarettes having wrappers formed of tobacco leaf the
application to the wrapper while it is being dried and filled of an envelope or
covering for the purpose of obtaining an even outer surface of the wrapper and
of protecting the wrapper while it is being filled substantially as described.
3. In the manufacture of cigarettes having wrappers formed of tobacco leaf the use
of a core or mandril comprising an elastic pipe or other suitable expansible and
contractible surface, an intermediate split tube or sectional body and an inner rod or
other device whereby the elastic pipe or expansible and contractible surface can
be caused to expand and contract as required substantially as described.
4. In the manufacture of cigarettes having wrappers formed of tobacco leaf
the use of expansible and contractible cores or mandrils substantially as shewn in
and described with reference respectively to Figs. 1 and 2 and Figs. 3 and 4 of the
accompanying drawings.
