I JACQUES JOSEPH GASTON AUBERT of 36 Rue de Provence, Paris, and of 56 Rue
des Petits Bois, Maisons-Lafitte, Seine et Oise, both in the Republic of France,
Gentleman do hereby declare the nature of this invention to be as follows:-
The paper serving for the manufacture of cigarettes comes from the manufacturor
in rolls and in order to render it marketable it has to be cut into small sheets and
gunimed.
To obtain this result economically I take the roll coming from the paper factory
and place it upon an axis where it is able to turn freely. Then taking one end of the
paper I pass it between a cylinder and a series of circular knives. Then I attach the
paper to be cut off by means of gum to a band which is led around an intermediate
drum to a drum on which it and the cigarette paper is wound. The cylinder against
which the knives cut has on its axis a wheel gearing with another wheel of the same
diameter upon the axis of the knives. The axis of the cylinder also carries a pulley
which by
a belt and another pulley of the same diameter gives motion to a roller
which bears with all its weight upon the drum on which the paper is wound. Thus
movement is given to all the system and the circumferential speed of the cutting
cylinder is the same as that of the winding drum.
The circular knives pressing upon the paper cut it into as many bands as there are
knives and of a width equal to their distance apart. The paper bands pass over the
wicks of a paste receiver and take up upon their edges a certain quantity of paste
which is dried as the paper passes over the intermediate drum which is hollow and
is kept at a sufficiently high temperature, either by means of steam or of hot air, and
it may be a gas flame or a lamp placed in its interior.
The bands thus cut apart and pasted are dried and rolled up upon the receiving
drun. They next require to be cut up into lengths and collected in bundles each of
a certain number. During the winding care is taken when the receiving drum has
made a certain number of turns marked by a counter, to interpose a coloured paper

page_text: between the two consecutive layers of cigarette paper. When a sufficient number of
turns is upon the drum I proceed to cut up the paper lengthwise the machine is
stopped and the paste reservoir is removed. The paper on the receiving drum is then
cut in a direction parallel to the axis of the cylinder and is spread out upon a table.
So a series of packets are obtained and these 1 then cut up into lengths by an
ordinary paper cutting machine. So I obtain piles of small sheets all ready grouped
and gummed and ready to be enclosed in packets for sale.
I apply india rubber between the roller or axis of the circular knives and the rings
on which are the cutting edges to compensate by its elasticity for any inequalities in
the dimensions of the rings.
The machine admits of variations; different gumming apparatus may be employed.
The cutting apparatus may be modified; and in place of applying paste I can moisten
the edges of the paper with water and project powdered gum against it.
In place of circular cutters all on the same axis I sometimes employ separate
cutting wheels each held in a fork by its axis. The fork is attached to a spring the
spring is clamped upon a support through which an axis passes having arms with
adjusting screws which can be brought to bear upon the springs.
This arrangement of cutting wheels carried by springs has the same object as india
rubber employed in connection with the circular knives which is to compensate for
irregularity; the cutting edges if perfectly rigid would not work satisfactorily.
In place of the cutting wheel bearing by the action of the spring against the
periphery of a cylinder it may bear against the side of the groove cut in the cylinder
the spring then pressing it laterally. Or flexible blade knives in like manner bearing
by their elasticity against the sides of grooves in the cylinder may be employed.

Improvements in Apparatus for Cutting and Gumming Paper
for Cigarettes.
I, JACQUES JOSEPH GASTON AUBERT, of 36 Rue de Provence, Paris, and of 56 Rue
des Petits Bois, Maisons-Lafitte, Seine et Oise, both in the Republic of France,
Gentleman, 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 :-
The paper serving for the manufacture of cigarettes comes from the manufacturer
in rolls and in order to render it marketable it has to be cut into small sheets and
gummed.
To obtain this result economically I take the roll coming from the paper factory
and place it upon an axis where it is able to turn freely. Then taking one end of the
paper I pass it between a cylinder and a series of circular knives. Then I attach the
paper to be cut off by means of gum to a band which is led around an intermediate
drum to a drum on which it and the cigarette paper is wound. The cylinder against
which the knives cut has on its axis a wheel gearing with another wheel of the same
diameter upon the axis of the knives. The axis of the cylinder also carries a pulley
which by a belt and another pulley of the same diameter gives motion to a roller
which bears with all its weight upon the drum on which the paper is wound. Thus
movement is given to all the system and the circumferential speed of the cutting
cylinder is the same as that of the winding drum.
The circular knives pressing upon the paper cut it into as many bands as there are
knives and of a width equal to their distance apart. The paper bands pass over the
wicks of a paste receiver and take up on their edges a certain quantity of paste which
is dried as the paper passes over the intermediate drum which is hollow and is kept at
a sufficiently high temperature, either by means of steam or of hot air, and it may be
a gas flame or a lamp placed in its interior.
The bands thus cut apart and pasted are dried and rolled up upon the receiving
drum. They next require to be cut up into lengths and collected in bundles each of
a certain number. During the winding care is taken when the receiving drum has
made a certain number of turns marked by a counter, to interpose a coloured paper
between the two consecutive layers of cigarette paper. When a sufficient number of
turns is upon the drum I proceed to cut up the paper lengthwise the machine is
stopped and the paste reservoir is removed. The paper on the receiving drum is then
cut in a direction parallel to the axis of the cylinder and is spread out upon a table.
So a series of packets are obtained and these 1 then cut up into lengths by an ordinary
paper cutting machine. So I obtain piles of small sheets all ready grouped and
gummed and ready to be enclosed in packets for sale.
I apply india rubber between the roller or axis of the circular knives and the rings
on which are the cutting edges to compensate by its elasticity for any inequalities in
the dimensions of the rings.,

wheels each held in a fork by its axis. The fork is attached to a spring the spring is
clamped upon a support through which an axis passes having arms with adjusting

DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a longitudinal elevation of the machine for cutting and gumming
the paper.
Figure 2 is a plan of same.
Figures 3, 4, 5 and 6 are detailed drawings of the various arrangements adopted
for obtaining the elasticity of the cutting implements (cutting wheels or portions of
cutting wheels).
The machine consists (sec Figures 1 and 2) of a paper-feeding cylinder A, on
which is first of all wound the continuous sheet of paper which is intended to be cut
up into bands or strips. This cylinder can easily be removed by hand, when
it is desired to renew the roll of paper; as the brackets which support it are open
at the top, it is merely necessary to take hold of it by the handles a in order to
remove it.
The paper, which unwinds itself in a continuous manner, on leaving the cylinder A
passes between the small metallic cylinder B and the circular knives or cutting
wheels C. It is by means of these knives that the operation of cutting up into strips is
effected.
For the purpose of gumming one of the edges of each strip thus obtained, a long
gum reservoir K is placed a little further on, furnished with nozzles kk, which pour
the gum on to the contiguous edges of two strips, so that each nozzle deposits the
gum on the edges of two strips of paper.
The drying of the gum is effected by causing the strips, when gummed, to pass
over a hollow drum D, raised to the requisite temperature either by means of steam,
or by hot air, or by means of a gas jet or a lamp placed inside.
The strips so cut gummed and dried are then wound on to the roller E.
Motion is communicated to the machine by means of the cylinders B and G, which
are connected by an endless belt. The cylinder G rests with all its weight on the
roller E which causes the paper to be drawn along.
The rotation of the cylinder B is effected either by hand by means of the crank X
or by a pulley with transmission belts.
To assist the rotation of the drying drum D an auxiliary cylinder H is interposed,
so that the paper is compelled to pass between the two.
At the commencement of the operation the end of the band of paper wound on the
roller A is gummed to a strip of ordinary paper fixed on the cylinder E and passing
through the points m, n and p; then the counterpoise P on the cutters C is let down
and the machine is ready to work.
The strips prepared by means of this machine are intended to be cut transversely
and classed by number. This classification is facilitated by interposing, during the
winding on, when the drum E has made a certain number of revolutions marked by
an index, a colored paper between two consecutive revolutions; then when the
drum E is sufficiently charged, the transverse cutting is proceeded with. To do this,

page_text: the machine is stopped, the gum reservoir K is removed and all the paper on the
cylinder E is split along one of the generating lines of the cylinder; a series of
packets is thus obtained, which are then divided into the desired lengths by means
of shears.
I will now pass on to the description of the cutting implement and describe the
means adopted to obtain the elasticity of each cutter; as before explained this is a
most important part of the invention.
Each cutter is held by a bracket c, Figure 3, fixed at the end of a spring r. At
its other end this spring is attached to a piece e, moving about a shaft f, bearing at
each end a counterpoise P. Each cutter is fixed on to the shaft f by means of an
adjusting screw v, which enables the distance between any two consecutive cutters to
be varied at will. When the cutters are in position the pressure which they are to
exercise on the paper is regulated by means of the screw u and the spiral spring 1.
In consequence of the rotation of the lower cylinder b, the cutters turn and cut the
paper while pressing on the cylinder b. By reason of this elasticity, blunt cutters
or knives may be used, the operative part of which is rounded instead of being
sharp.
Experience has shown that instead of moveable cutters, fixed cutters or knives
(Figures 4 and 5) might be employed. The same arrangement as in the preceding
case is adopted to obtain elasticity, but the cutter now does not revolve on its axis ;
but in this case the cutters must be well sharpened. When the working part becomes
blunt, the screw is undone, and the cutter is turned through a small angle, a new
cutting part is thus obtained. Figure 5 shows an arrangement in which the fixed
cutting wheel is replaced by a fixed knife g, or portion of a cutting wheel.
The elasticity may also be obtained by mounting the sharp cutting wheels m, on
india rubber washers o (the spring of the previous systems being suppressed); the
cutters may be separated by means of sockets d (Figure 6).
Or again it is obvious that the elasticity may be given to the cutting apparatus by
having an elastic bed for the paper to rest upon whilst being cut.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. Elastic cutting implements, whether they consist of moveable cutting wheels,
fixed cutting wheels or knives, mounted elastically or mounted rigidly and working
on an elastic bed.
2. The cutting implements substantially as described and shown in Figures 3. 4.
5 and 6.
3. The apparatus for cutting and gumming paper for cigarettes substantially as
described and shown in the drawings.
