Improvements in Machines for Manufacturing Paper Tubes suitable
for Cigarettes.
Ι I PAUL VICTOR MAURICE BLACHE of 21 Boulevard Poissonniere Paris in the
Republic of France Engineer do hereby declare the nature of this invention to be
as follows:-
1-
This invention relates to the mechanical manufacture of tubes of paper suitable
for cigarettes and it presents relatively to the product obtained, great advantages
over the systems heretofore employed.
A tube manufactured in this improved machine can be printed on or bronzed in
the direction of its length in one or several colours goffered and ornamented with
filigree work; it may also receive an impression in any colors at the overlapping
part forming the joint between the two edges of the sheet.
The strip of paper wound in the form of a roll or hobbin is placed upon a drum
or reel provided with a removeable cheek or flange which screws upon the boss and
enables the reel to take bobbins of different widths. The reel itself is capable of
being displaced or of sliding longitudinally upon its axis under the action of a
spring so that by means of an adjusting nut bobbins of different widths can be
adjusted to coincide with the working axis of the machine.
The reel is also provided with two pins which connect it to a brake pulley
rotating with the reel. Around this pulley is passed a band acting as a brake
strap controlling the unwinding of the paper. This brake strap is connected by a
spring to a set screw which enables the retarding action of the brake to be
regulated as required.
The paper is taken from the reel round a roller which rotates on one arm of a
cranked lever rocking on an axis and is caused to move simultaneously with the
carriage by means of a connecting rod and lever by which the other arm of the
cranked lever is connected to the carriage so that the quantity of paper which bas
to be drawn on in the forward motion of the carriage is unwound from the reel
when the carriage moves back.
When
The paper is drawn over a curved guide and passes over a roller or cylinder
provided on one side with a small wheel or enlargement with or without teeth
rotating in a trough containing cementing material. By these means a narrow
streak of adhesive matter is deposited on the edge of the strip of paper.
the wheel is toothed a series of spots are formed in place of the streak, the
object of such arrangement being simply to reduce the quantity of adhesive matter
employed.
The strip of paper then passes under a goffering device the engraved part of
which is attached to a moving part pressure to which is applied by means of a cam
or eccentric which may be worked by a slotted connecting rod and the forked
lever. This goffering device also acts as a clamping device serving to prevent the
paper from moving back when the bobbin is being unwound.
The paper then passes to a table placed upon the carriage.
At the proper
moment and during the forward motion of the carriage a sector presses upon this
table, the said sector partaking very accurately of the movement of the carriage by
means of a toothed sector or quadrant and a rack. The under surface of the sector
is engraved and at the same time as it draws forward the paper it imprints the

page_text: engraved design thereon. This sector may receive its pressure by means of a crank
and forked lever.
This impressing process in combination or not with inking forms an important
part of this invention.
It is evident that by providing the machine with a series of small tables and
sectors similar to those above described and by covering the engraved parts of such
sectors with bronze powder or a variety of inks the paper may be printed or bronzed
with as many colors as required.
For the purpose of printing on the paper an engraved cylinder is used, and the
inking apparatus is placed above this cylinder.
The ink contained in ink troughs is distributed by cylinders and rollers and
transferred to the inking tables and over the engravings.
The movement of the distributing cylinders and rollers may be obtained by
means of levers operated by a pin or stud attached to the engraved cylinder.
This engraved cylinder is mounted on an eccentric axis controlled by the aforesaid
crank of the sector by means of a forked lever to give the pressure. The rotation
of this cylinder is determined by the movement of the carriage which may be done
by means of a wheel and rack.
After receiving these several impressions the strip of paper is rolled longitudally
upon a fixed sheath or mandrel and enters a ring which supports the paper and
bends it into the form of a tube. The ring is maintained by a lever which prevents
its longitudinal displacement.
On leaving the ring a sector moving very accurately with the carriage is caused
in the course of the forward movement to press upon a rod attached to the carriage
and sliding in the fixed sheath or hollow mandrel or rather upon the two overlapping
edges of the paper.
This sector is provided with an engraved part which prints by pressure upon the
joint of the tube in precisely the same way as that herein before described and which
forms an important part of this invention. The rotation of this sector can be
produced by a wheel and rack mounted on a bridge. The pressure is given by an
eccentric axis controlled by the aforesaid crank by means of a forked lever.
The deposit of ink upon the characters or printing surface of the sector is effected
by means of rollers carried on fixed axes so that the contact of these rollers
with the engraved part of the sector is obtained by the movement of the sector
itself.
The sector produces by mere pressure sufficient adhesion to ensure a perfect
union.
In order that the paper may not partake of the backward movement of the
carriage, a gripper acted upon by a part on the crank holds it on the aforesaid
fixed sheath.
To diminish the tendency of the rod to bend under the pressure of the sector
there is placed on the end of the carriage the aforesaid bridge piece which at the
same time serves for drawing forwards the paper which is held between the bridge
piece and the rod and partakes of their motion.
The tube thus formed is cut into equal lengths by shears to which movement is
imparted by a lever worked by the aforesaid connecting rod by means of a pin on
the said rod working in a slot in a lever connected with the shears.
In the case of a cigarette machine there is employed a series of moveable rods
or mandrels revolving upon a ceutral axis and arranged to receive the tubes.
These rods or mandrels are shifted at each operation so as to remove the manu-
factured tube and present it before the orifice of the compresser, distributor or
other device employed to fill the tubes with tobacco. The rods are then removed
from the tubes during the introduction of the tobacco by the action of the
pusher.
In order to enable the machine to make tubes of cigarette paper of different
lengths the goffering device and the printing mechanism are placed upon moveable
supports or brackets which are capable of adjustmeut in the direction of the length

page_text: of the table. The movement or stroke of the carriage is regulated by adjusting
the connecting pin of the reciprocating rod or piston.
The machine receives motion in any suitable way for example from pulleys placed
upon a shaft which transmits motion through toothed gearing to a cam disc which
moves the carriage by means of a link and lever and controls the aforesaid crank
by a lever.

Improvements in Machines for Manufacturing Paper Tubes, suitable
for Cigarettes.
I, PAUL VICTOR Maurice Blache, of 21 Boulevard Poissonière, Paris, in the
Republic of France, Engineer, 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 the mechanical manufacture of tubes of paper suitable
for cigarettes, and it presents relatively to the product obtained, great advantages
over the systems heretofore employed.
A. tube manufactured in this improved machine can be printed on or bronzed in the
direction of its length in one or several colours, gauffered or embossed with ornamental
or filagree work; it may also receive an impression in any colours at the overlapping
part forming the joint between the two edges of the sheet.
I will describe my invention with reference to the accompanying drawings.
Fig. 1 is a longitudinal section, and
Fig. 2 is a plan of a machine constructed according to my invention.
Fig. 3 is a sectional elevation taken on line 1, 2, 3, 4 of Fig. 1.
Figs. 4, 5, 6, 7, 8 and 9 are transverse sections taken on lines 5-6, 7-8, 9—10,
11-12, 13-14, and 15-16 respectively of Fig. 1.
Fig. 10 is a section of the printing device drawn to a larger scale and
Fig. 11 is a face view of the said device looking to the right from the line 17-18
of Fig. 1.
The strip of paper from which the tubes are formed is wound in the form of a
roll or bobbin and placed upon a drum or wheel A, provided with a removeable
cheek or flange a which screws upon the boss and enables the reel to take bobbins
of different widths. The reel itself is capable of being displaced or of sliding
longitudinally upon its axis under the action of a spring a' so that by means of an
adjusting nut a bobbins of different widths can be adjusted to coincide with the
working axis of the machine.
The reel is also provided with two pins a² which connect it to a brake pulley a³
so as to cause it to rotate with the reel. Around this pulley is passed a band or
strap a acting as a brake to control the unwinding of the paper. This brake strap
is connected by a spring a to a set screw as which enables the retarding action of
the brake to be regulated as required.
The paper is conducted from the reel round a roller B which rotates on one
arm of a bell crank lever b, rocking on an axis 63 and caused to move simultaneously
with a carriage C (along which the paper passes to the tube forming device) by
means of a connecting rod b' and lever by which the other arm of the bell crank
lever is connected to the carriage so that the quantity of paper which bas to be
drawn on in the forward motion of the carriage is unwound from the reel A when
the carriage moves back. The paper is drawn over a curved guide D and passes
thence over a roller or cylinder E provided on one side with a small wheel or

page_text: enlargement with or without teeth rotating in a trough containing cementing
material. By these means a narrow streak of adhesive matter is deposited on the
edge of the strip of paper. When the wheel is toothed a series of spots are formed
in place of the streak, the object of such an arrangement being simply to reduce the
quantity of adhesive matter employed.
The strip of paper then passes under a gauffering or embossing device F (Fig. 9)
the engraved part of which is attached to a moving part and pressure to which
is applied by means of a cam or eccentric f2 which may be worked by a slotted
connecting rod G and the forked lever f Figs. 2 and 9. This gauffering or embossing
device also acts as a clamping device serving to prevent the paper from moving back
when the bobbin is being unwound.
The paper passes from the gauffering or embossing device to a table C¹ fixed
upon the carriage C. At the proper moment and during the forward motion of
the carriage a sector F¹ presses upon this table, the said sector partaking very
accurately of the movement of the carriage by means of a toothed sector or
quadrants and a rack s¹ Fig. 3. The surface of the sector F' is engraved and at
the same time as it draws forward the paper it imprints the eugraved design thereon.
This sector Freceives its pressure by means of a crank rod G and forked lever g²,
see Fig. 2.
This impressing process in combination or not with inking mechanism forms an
important part of this invention.
It is evident that by providing the machine with a series of small tables and
sectors similar to those above described and by covering the engraved parts of such
sectors with bronze powder or a variety of inks the paper may be printed or bronzed
with as many colours as required.
For the purpose of printing on the paper a name, trade mark or other design in
addition to that produced by the sector F an engraved cylinder H is used and the
inking apparatus is placed above this cylinder.
The ink contained in troughs h is transferred by cylinders h¹ and rollers h² to
rollers h³ which distributes it over the engraved cylinder H.
The movement of the cylinders h¹ and rollers h² is obtained by means ofvers h
and operated by a pin or stud h on the engraved cylinder H see. 10. This
cylinder H is mounted on an eccentric axis controlled by the crank rod G and a
forked lever g to give the pressure, see Fig. 2, 10 and 11. The extent of rotation
of the cylinder H is determined by the movement of the carriage by means of
the rack s gearing with the wheel r¹.
After receiving these several impressions the strip of paper is rolled longitudinally
upon a fixed sheath or mandrel 1 and enters a ring K Figs. 1, 2 and 7 which supports
the paper and bends it into the form of a tube. The ring K is maintained by
a lever which prevents its longitudinal displacement.
On the partially formed tube leaving the ring K a sector L (Figs. 1 and 5)
moving accurately in time with the carriage is caused in the course of the
forward movement to press the two overlapping edges of the paper tube against
a rod M attached to the carriage and sliding in the fixed sheath or hollow
mandrel I.
This sector L is provided with an engraved part which prints by pressure upon
the joint of the tube in precisely the same way as that hereinbefore described and
which forms an important part of this invention. The rotation of this sector L is
effected by means of a wheel s² gearing with a rack mounted on a bridge P. The
necessary pressure is given by an eccentric axis controlled by the crank rod G by
means of a forked lever g³.
The deposit of ink upon the characters or printing surface of the sector L is
effected by means of rollers Fig. 12 carried on fixed axes so that the contact of
these rollers with the engraved part of the sector is obtained by the movement of
The sector itself.
The sector L produces by mere pressure sufficient adhesion to ensure a perfect
union of the edges of the paper tube.

page_text: In order that the paper may not partake of the backward movement of the carriage
a gripper N Figs. 1, and 6 acted upon by the part g on the crank rod G holds it
securely on the aforesaid fixed sheath I.
To diminish the tendency of the rod M to bend under the pressure of the sector L
the end of the rod M is supported by the bridge piece P which at the same time
serves to draw forward the paper which is held between the bridge piece and the
rod and partakes of their motion.
The tube as it is formed is cut into equal lengths by shears R to which
imparted by a lever worked by the crank rod G by means of a
pin on the said rod working in a slot in the lever (see Fig. 2) connected with
movement
the shears.
The tube forming mechanism may be combined with a cigarette machine in
which case a series of moveable rods or mandrels revolving upon a central axis may
be provided and arranged to receive the tubes. These rods or mandrels may be
shifted at each operation so as to remove the manufactured tube and present it
before the orifice of the compresser, distributor or other device employed to fill the
tubes with tobacco the rods being removed from the tubes during the introduction
of the tobacco by the action of the pusher.
In order to enable the machine to make tubes of cigarette paper of different
lengths the gauffering or embossing device and the printing mechanism are carried
by movable supports or brackets Qwhich are capable of adjustment in the
direction of the length of the table S. The movement or stroke of the carriage can
be regulated by adjusting the position of the connecting pins by which the connecting
rod is attached to the bell crank lever b and that by which the rod, U operated
by the cam j is connected to the lever b².
The machine may be driven by any suitable motor by a strap and pulleys y on a
shaft J which transmits motion through toothed gearing to the cam disc see
Figs. and 3. The disc moves the carriage C by means of the link U
aud lever and transmits motion by a lever to the crank rod G.
the lever is connected by the rod the bell crank lever b which carries the
winder B.
