MAX CAMPE and LOUIS CAMPE both of Berlin German Empire
IN PAPER-BAG MACHINES,"
"IMPROVEMENTS
This invention relates to machines for the manufacture of paper-bags either
three-cornered or four cornered.
According to the said invention the paper from which the bags are to be made
is first rolled upon a reel and after passing over a smoother its free end is then
engaged between two pairs of rollers. The upper roller of each pair is movable
vertically within a guide, and is pressed upon the lower roller by means of a spring.
The paper is thus held fast between the upper and lower rollers so that by the
rotation of the lower rollers it is drawn from the reel.
The paper is brought under a movable cutter between the two pairs of rollers,
and after the paper has been inserted between the second pair of rollers the
rotation of the driving axle and a pulley causes the machine to operate auto-
matically to cut the paper in proper lengths, paste it, fold it and stick it together,
and throw off the made up bags, until the paper is all worked off the said reel.
During the working, the machine is left to itself, and warns automatically, by
means of a bell or other signal, when the last remnant of paper is worked off. To
this end an angular piece or tappet is placed at the side of the reel, and is free to
rotate upon a pivot. The said angular piece, being held down at one side by the
rolled paper upon the surface of the reel, extends a spring which, when the paper
has been completely unrolled, forces the vertical arm of the said angular piece
outwards. The paper is unrolled in such a manner that the reel must rotate in
one direction. The said vertical arm then strikes against a lever which moves by
means of a bar or connecting rod and a second lever, and thereby causes a third
lever, pivoted on a pin, to swing with its extremity which was previously carried
LD 077

page_text: by the first lever, downwards, the third lever being acted upon by a weight. The
handle of a small hammer is thereby set free, and in consequence of the pressure
exerted by its spring, it strikes upon a bell; at the same time as the second lever
falls the band or belt shifter is pushed sideways by means of a bar and an angular
lever movable around a pin fixed to the frame of the machine, whereby the band
or belt is forced from the fast pulley on to the loose pulley, so that the machine
comes at once automatically to rest at the same time that the signal is given.
The whole mechanism of the machine is set in motion by the driving axle which
carries the fast and loose pulleys. The different operations of the machine are
effected by means of toothed wheels and other gearing.
I provide a table upon which are carried the devices such as the shifter or
device for turning over the sheets of paper, the folding blades for folding the paper
and sticking down the same, the bag-removing apparatus, and other parts.
The lower rollers, through whose rotation the paper is drawn from the reel,
carry on their axles toothed wheels which receive their motion from the driving
shaft through gearing comprising two bevel wheels and a shaft carrying a cam
wheel, which at intervals causes a spur-wheel to rotate and thereby transmit its
rotary motion to the aforesaid toothed wheels on the axles of the rollers. On the
said shaft are two cams, which, through their rotation lift the frame which carries
the knife or cutter, which frame is guided at its sides by pieces fixed to the
aforesaid table. At the moment when the cutter falls, and cuts through the paper
the roller gear rests for a short time while a part of the said cam-wheel not
provided with teeth, passes under one of the toothed wheels so that no motion can
thus ensue.
The rollers are again set in motion when the cutter is so far lifted by
cams that a free passage is made for the next length of paper which is to be cut.
The aforesaid shifter is provided with nippers which are pressed down fast upon
the sheet of paper by means of springs as soon as, by the oscillation of the shifter,
they have become disconnected from two pins which are fixed to the said table.
Moreover the air-pressure occasioned by the oscillation prevents the sheet from
moving upon the shifter during the greater part of the oscillation which is
necessary in order to obtain by the subsequent folding and pasting, a bag well
formed and free from defects.
A paste-wheel of suitable width is provided at the side of one of the rollers
against the periphery of the said wheel, a small wheel below which moves in a
paste trough, presses, and thus transfers to the paste-wheel a part of the paste it
has taken up. The paste-trough can easily be drawn from its place on the frame
of the machine, for filling and other purposes; and the contact of the small wheel
with the paste wheel is effected in a simple manner by placing wedge-shaped pieces
between the bottom of the paste-trough and its frame.
When the shifter is thrown back the first folding blade movable around the axes
of the two toothed sectors is also thrown back, the said shifter and blade being
connected by means of rods and levers so that they must perform similar move-
ments. To the said shifter is attached a curved link and to the arm of the said
blade is also attached a curved link, the said links being connected to each other
by a rod capable of being moved backward and forward under the said table in
guides or bearings. The said links are made to protrude at certain intervals from
slits cut in the said table, in order to throw the sheet upon the table.
In order that the shifter on being moved from left to right, whereby a similar
motion of the first folding blade is effected, should be able to let the paper. fall
freely, on each of the shorter arms of the nippers is attached a string, both of
which strings are attached to a common drawing string connected with the frame
of the machine. The length of the latter string is so measured that when the
shifter on oscillating towards the right has reached a certain position over the
table, the tension upon the strings causes the nippers to be lifted from the sheet,
so that the latter falls down, ready for folding and sticking upon the bottom of the
table. The first folding blade is then also thrown back to the right, and rests
upon the table.

page_text: From the table projects a pin by means of which the sheet of paper is made fast
by the descent upon it of the first folding blade, which is provided with a hole
corresponding to the pin. A similar perforation of the paper is effected by means
of the second folding blade, when the latter folds the sheet diagonally. This
perforation of the bags allows of their being strung.
The shifter and blade return to their position and the triangular part of the first
folding blade lies upon the sheet in such a manner that the pasted side which,
owing to the paper being turned over, is now uppermost, lies parallel to the longer
edge of the said blade without being covered by it. The mechanism for effecting
this movement consists of a shaft placed above the driving shaft, and carrying a
spur-wheel which gears with another spur-wheel on the driving shaft. Through
the rotation of the said shaft a toothed sector is made to revolve in the game
direction. The latter gears at the proper time with another toothed sector whose axis
coincides with that of the pivots around which the first folding blade turns. The
toothed sector on the upper shaft is only made to revolve in one direction and can
thus turn the said blade and the shifter connected therewith, by means of rods, in
one direction only. Another toothed sector fixed upon another shaft serves for
turning the shifter and blade in the opposite direction. Upon this latter shaft is
fixed a small spur-wheel which receives its motion, by means of an intermediate
wheel, from a small spur-wheel on the driving shaft, thus effecting the rotation of
the toothed sector upon the said shaft and thereby the toothed part of the former
gears at the proper time with a toothed sector whose axis corresponds with that of
the pivots of the first folding blade. When the first folding blade, together with
the shifter, is brought into one psoition, a second folding blade on which half of
the sheet lies, is turned upon its pivots and thereby folds the sheet diagonally, so
that the sheet formerly lying upon two folding blades lies in between them, the
pasted edge of the sheet remaining uncovered.
The oscillation of the second folding blade is effected by means of sectors which
are rotated in opposite directions and gear at the proper time with the sectors of
the second folding blade. One of these sectors is fixed upon a shaft placed
diagonally and receives its motion from another shaft upon which is a bevel-wheel
gearing with another bevel-wheel on an intermediate shaft, which by means of a
bevel wheel at its other end gears with a bevel wheel fixed upon the shaft carrying
the said sector. Another of the said sectors moving in the opposite direction is
fixed upon a shaft and rotates by means of another shaft carrying a bevel wheel
which gears with a bevel wheel on the driving shaft. Upon one of the said shafts
is fixed a spur wheel which gears with a spur wheel on a shaft placed above it.
The latter carries a bevel wheel and this is connected with a bevel wheel upon
another shaft carrying a second bevel wheel gearing with a bevel wheel on the
shaft carrying the said sector.
The second folding blade by means of which the sheet is folded diagonally,
carries by means of pivots a smaller blade which follows the oscillatory movements
of the second folding blade. One corner of this smaller blade projects a little
beyond the diagonal of the sheet.
Whilst the sheet lying on the first folding blade is covered by the said second
and smaller folding blades, a side blade upon which the pasted edge of the paper
rests is made to oscillate and thereby catches from below a small spring plate on
the smaller blade.
The oscillation of the side blade is effected by two toothed sectors fixed upon
two shafts. The rotation of one of these shafts is effected by means of suitable
gearing from the driving shaft. The said toothed sectors operate other toothed
sectors connected with the side blade.
As the first folding blade rises again from the table it strikes with its point,
which carries the completed bag, against an ejector. This ejector consists of a bar
projecting upwards from the table, carrying at its upper end a toothed nipper for
catching the bag, and being fastened at its lower extremity to one end of a double
armed lever. The other end of this lever is provided with a weight which serves,

page_text: at the proper moment, whilst the said blade lies with the bag against the aforesaid
nipper, to propel the bar upward in order to strike off from the blade point the
bag caught by the nipper, and to throw it against a receiving table whence it falls
into a basket below.
The catching of the completed bag placed upon the point of the first folding
blade is contrived by a cam which is fixed upon the driving shaft and moves
upwards a pin projecting sideways from the said lever. This latter falls at the
right time from the higher part of the cam and thereby throws up the ejector.
For working a counter a small spur wheel is placed on a pivot underneath the
table, on which there is a pin which, every time a bag is thrown off, pushes
forward one tooth of the gearing of the said counter whereupon the number of the
bags manufactured is shewn by the counter. The small spur wheel receives
motion immediately from a small spur wheel on the driving shaft.

MAX CAMPE and LOUIS CAMPE, both of Berlin, German Empire, “IMPROVEMENTS
IN PAPER-BAG MACHINES
"
This invention relates to machines for the manufacture of paper-bags having
either three or four corners.
According to the said invention the machine is constructed as follows, that is to
say, the paper from which the bags are to be made is rolled upon a reel d and
after passing over a smoother its free end is passed between a pair of rollers b', c',
as shown in Figure 2. The upper roller c' of this pair, as also the upper roller c of
another pair b, c, are movable vertically within guides, and are pressed upon the
lower rollers by means of springs. The paper is thus held fast between the
rollers b' and c', so that, by the rotation of the lower roller b', it is drawn from
the reel d. After leaving the pair of rollers 6¹, c¹, the paper passes under a movable
cutter M (Figure 3) and is led between the second pair of rollers b, c. After the
paper has been inserted between the second pair of rollers, the rotation of the
driving axle w by means of a pulley and belt a' causes the machine to operate
automatically to cut the paper in proper lengths, paste it, fold it, stick it together
and throw off the finished bags until the paper is all worked off the reel d.
A bell is automatically arranged to give warning when the said reel is empty.
To this end an angular piece or tappet m³ (Figures 5, 6 and 7) is placed at the side
of the reel d and is free to oscillate upon a pivot. The said angular piece is held
down at one end by the paper rolled upon the surface of the reel and a spring is
arranged which, when the paper has been completely unrolled, draws the vertical
arm of the said angular piece m outwards. The paper is unrolled in such a
manner that the reel rotates in the direction of the arrow. The said vertical arm
then strikes against a lever m³ which, by means of a bar or connecting rod m³,
moves a lever m* and thereby causes a lever pivoted on a pin e (Figure 1) to swing
with its extremity, which was previously carried by the lever m, downwards, the
lever m³ being acted upon by a weight m³. The handle n' of a small hammer
(Figure 6) is thereby released and, in consequence of the pressure exerted by a
spring, it strikes upon the bell n². At the same time that the lever m³ falls, the
band or belt-shifter m is moved laterally by means of a bar m² and an angular
lever m¹ movable around a pivot e¹ fixed to the frame R of the machine, whereby
the band or belt is shifted from the fast pulley a¹ on to a loose pulley a so that
the machine comes at once to rest at the same time that the warning signal is
given.
The machine is driven by the axle w which carries the fast and loose pulleys a
and a. The different operations of the machine are effected by means of toothed
wheels and other gearing as hereinafter set forth. The direction of rotation of the
shafts which impart motion to each individual working part of the machine is
indicated throughout the drawings by arrows which encircle the shafts. For the
sake of clearness in the drawings, in the vertical sections, the pitch line alone of the
toothed wheels is indicated by dotted lines.
T is a work-table upon which are carried the shifter or device u for turning over
the sheets of paper, the blades K1, K2, for folding the paper and sticking down the
same, the bag removing apparatus and other parts.
The paper after leaving the reel d passes between the rollers b', c¹, and b, c, and
after having been cut into suitable lengths by the movable cutter M arrives upon

page_text: the device u which is provided with hinges u, u, on the table T, which device 18
thrown back (Figures 3 and 4).
The rollers b', b, through whose rotation the paper P (Figure 2) is drawn from
the reel d, carry on their axles toothed wheels 30 and 29 which receive their
motion from the driving shaft w through the bevel-wheels 23 and 24, the shaft w³,
the bevel-wheels 25 and 26 and the shaft w. The shaft w³ carries a cam-wheel 27
which, at intervals, causes the spur-wheel 28 (Figure 2) to rotate and thereby
transmit its rotary motion to the toothed wheels 30 and 29.
On the shaft w³ are two cams y which through their rotation lift the frame
which carries the knife or cutter M, the said frame is guided at its sides by the
pieces f, f, fixed to the table T. At the moment when the cutter falls and cuts
through the paper, the roller gearing rests for a short time while the part of the
cam-wheel 27 not provided with teeth passes under the toothed wheel 28
(Figure 2) so that no motion can thus ensue. The rollers are again set in motion,
when the cutter is so far lifted by the cams y³, y², that a free passage is made for
the next length of the paper which is to be cut.
The aforesaid device u is provided with nippers u¹, u', (Figures 8 to 10, 15 and
21) which are pressed down fast upon the sheet of paper B by means of springs u³, u³,
as soon as by the oscillation of the shifter or device u, they have become discon-
nected from the two pins us, us, which are fixed to the work-table T. Moreover,
the air pressure occasioned by the said oscillation prevents the sheet from moving
upon the device u during the greater part of the oscillation, which is necessary in
order to obtain, by the subsequent folding and pasting, a bag well formed and free
from defects. The lower surface of the upper edge of the sheet B (Figure 15) is
readily pasted by the following means when it reaches the device u, that is to
say: A paste wheel of suitable width is provided at the side of one of the rollers b;
against the periphery of the said wheel a small wheel e below, which moves in a
paste-trough, presses and thus transfers to the paste-wheel a part of the paste it
has taken up. The paste-trough can easily be drawn from its place on the frame
of the machine for filling and other purposes, and the contact of the small wheel e
with the paste-wheel is effected in a simple manner by placing wedge-shaped pieces
between the bottom of the paste-trough and its frame.
When the device u is thrown back (Figures 4, 8 and 15) the folding blade K'
(movable around the axes of the toothed sectors IX X) is also thrown back (to the
left) the said device and blade being connected by means of rods and levers so that
they must perform similar movements. To the device u is attached a curved
link K and to the arm K of the said blade K¹ is also attached a curved link K
the said links being connected to each other by a rod K' which is capable of being
moved backward and forward under the said table T in the guides or bearings K⁹.
The said links are caused, by the oscillation of u and K¹, to protrude from slits cut
in the said table T (Figure 9) the link K³ protruding, when the device u is in the
position indicated by dotted lines, in order to throw the sheet B upon the table
(Figures 16 and 21).
In order that the device u, on being moved from left to right, (whereby a similar
motion of the folding blade K' is effected) may allow the paper to fall freely. I
attach to each of the shorter arms of the nippers u', u', a string u², both of which
strings are attached to a common-drawing string u connected with the frame of
the machine. The length of the latter string is so measured that, when the device u,
in oscillating towards the right, has reached a certain position over the table T,
the tension upon the strings u³, u³, u, causes the nippers u¹, u¹, to be lifted from
the sheet B so that the latter falls down, ready for folding and sticking, upon the
bottom of the table and thus assumes the position shewn in Figure 16 by the
diagonal section lines. The folding blade K' is then also thrown back to the
right, and rests upon the table T, as shown in Figure 16. From the table projects
a pin (Figures 15 and 16), by means of which pin the sheet of paper is made
fast and perforated by the descent upon it of the blade K¹ which is provided with
a hole corresponding to the pin. A similar perforation of the paper is effected by

page_text: means of the folding blade K2 when the latter folds the sheet diagonally. This
perforation of the bags allows of their being strung.
The device u and the blade K¹ return to their position on the left as shown in
Figures 17 and 20, the triangular part of the folding blade K¹ lies upon the
sheet B in such a manner that the pasted side, which, owing to the paper being
turned over, is now uppermost, lies parallel to the longer edge of the blade Ki
without being covered by it. The mechanism for effecting this movement consists
of the shaft w placed above the driving shaft w and carrying a spur-wheel 2
which gears with the spur wheel 1 on the driving shaft w. Through the rotation
of the shaft w¹, the direction of which is indicated by the arrow (Figure 9), a
toothed sector III is caused to revolve in the same direction. The said sector
gears, at the proper time, with the toothed sector IX (Figures 4 and 9) whose
axis coincides with that of the pivots around which the folding blade K¹ turns.
The toothed sector III is only caused to revolve in one direction and can thus turn
the blade K, and the device u connected therewith by means of rods, in one
direction only, that is to say, from right to left. The toothed sector IV fixed upon
the shaft w serves for turning the device u and blade K¹ in the opposite direction.
Upon the shaft w³ is fixed a small spur-wheel g (Figures 1, 3 and 9) which
receives its motion by means of an intermediate wheel from the spur-wheel 7 on
the driving shaft, thus effecting the rotation of the toothed sector IV which is opposite
in direction to that of the sector III, and thereby the toothed part of the sector IV
gears, at the proper time, with the toothed sector X whose axis corresponds with
that of the pivots of the folding blade K³.
But before this rotation of K¹ to the right by means of the sector IV takes place,
the sheet B must be folded and pasted round the triangular point of K¹. When
the folding blade K' together with the device u are brought into their position to
the left (Figures 17 and 20) the folding blade K*, on which half of the sheet B
lies, is turned upon its pivots placed in a diagonal 8, and thereby folds the sheet
diagonally so that the half of the sheet formerly lying upon the folding blades K¹
now lies between the blades K¹ K³, the pasted edge of the sheet remaining
uncovered.
The oscillation of the folding blade K³ is effected by means of the sectors I
and II, which are rotated in opposite directions and gear, at the proper time, with
the sectors VII and VIII of the folding blade K (Figures 11 and 12). The sector I
is fixed upon a shaft w" (Figure 1) and receives its motion from the shaft w¹
(Figure 2) upon which is a bevel-wheel 3 gearing with the bevel-wheel 4 on an
intermediate shaft wo, which by means of a bevel-wheel 5 at its other end, gears
with a bevel-wheel 6 fixed upon the shaft wll, the rotation of the two shafts being
in the direction of the twisted arrows. The sector II, moving in the opposite
direction, is fixed upon the shaft w¹ and rotated by means of the shaft w carrying
a bevel-wheel 11 which gears with the bevel-wheel 10 on the driving shaft w.
Upon the shaft w³ is fixed a spur-wheel 15 which gears with a spur-wheel 16 on
the shaft w¹s placed above it. The shaft w" carries a bevel-wheel 17 and this is
connected with a bevel-wheel 18 upon the shaft w¹s carrying the bevel-wheel 19
gearing with the bevel-wheel 20 on the shaft w. The rotation of this shaft takes
place in the direction indicated by the twisted arrow (Figure 1).
The folding blade K³, by means of which the sheet B is folded diagonally, carries
by means of pivots a smaller blade K which follows the oscillatory movements
of the folding blade K. The corner o of this blade K' projects a little beyond the
diagonal of the sheet (Figure 18) for the purpose hereinafter specified.
Whilst the sheet, lying on the folding blade K¹, is covered by K³ and K' the
side blade K³, upon which the pasted edge of the paper rests, is made to oscillate
and thereby catches from below a small spring-plate g¹ on the blade K* and the
latter is thus raised a little in order to make room for the complete turning over
of K³ together with the pasted edge of the paper lying there. This latter blade
then presses the said edge fast upon the upper side of the paper, and a bag D
(Figures 19 and 22) is, in the main details, completed.

page_text: The oscillation of the side blade K³ is effected by the two toothed sectors V
and VI, the first of which is fixed upon the shaft w7 and the latter upon the
shaft w¹ (Figures 1, 3 and 14).
The rotation of the shaft w is effected by means of the shaft w (Figures 1 and 3)
and spur-wheel 12 which gears with a spur-wheel 13 above it fixed to the shaft w,
the spur-wheel 13 turns the spur-wheel 14 of the shaft w. The toothed sector V
operates the sector XI placed on the blade K³ and the toothed sector VI operates,
in a contrary direction, the sector XII.
The sectors I and II for operating the blade K², the sectors III and IV for
operating the blade K' and also the sectors V and VI for operating the blade K³
are to be considered as portions of wheels or cams, which have on their circum-
ference a number of teeth accurately computed so as to bring about, at the proper
time, the necessary motions of the blades through gearing with the sectors of the
said blades by means of the rotation of the different shafts. The arrangement is
so contrived that all the blade-motions necessary for the production of a bag are
completed by one revolution of the driving shaft.
After the blades K and K³ have formed the bag D through the folding and
sticking of the sheet B around the blade K¹ (Figure 19) the blade K³ returns to
its position (Figure 20) and immediately afterwards the blade K³ returns to the
position shewn in perspective in Figure 21. By the backward movement of the
blade K² the corner o of the blade K connected with K2 is caused to lie upon
the corner S¹ of the pasted edge of the bag (Figure 22) and bends it round under
the lower side of the bag, whereby, through the pressure of a spring-plate O
(Figure 23) fastened to the table T which is depressed at the same time, a
strong and durable point to the bag is produced such as heretofore could only be
manufactured by hand.
After this operation the blade K³ returns to the position shewn in Figure 15.
Meanwhile a sheet of paper B has been fed by the rollers to the device u and the
operation is repeated; the device u and blade K' coming into their respective
position as in Figure 16, whereupon the folding and sticking of the new sheet now
lying on the table is effected as above described.
As the folding blade K¹ rises again from the table it strikes with its point, which
carries the completed bag, against an ejector y (Figures 3, 4, and 21). This ejector
consists of a bar projecting upwards from the table and carrying at its upper end
a toothed nipper for catching the bag, this bar is fixed at its lower extremity to
one end of a double armed lever x. The other end of this lever is provided with
a weight which at the proper moment, that is to say, whilst the blade K' lies
with the bag against the aforesaid nipper, moves the said bar upwards in order to
strike off from the blade-point the bag caught by the nippe, and to throw it against
a receiving table S (Figure 3) whence it falls into a basket below.
The catching of the completed bag placed upon the point of the folding blade K¹
is effected by a cam y¹ (Figure 3) which is fixed upon the driving shaft w and
moves upwards a pin projecting sideways from the lever x. This lever falls at
the proper time from the higher part of the cam and thereby throws up the
ejector.
For operating a counter z (Figure 4) a small spur-wheel 22 is placed on a pivot
w (Figure 1) underneath the table, on which there is a pin i (Figure 3) which,
every time a bag is thrown off, pushes forward one tooth of the gear-wheel 31 of
the said counter, so that the number of bags manufactured is shown by the counter.
The spur-wheel 22 receives motion directly from a small spur-wheel 21 on the
driving shaft w (Figure 3).
Having thus fully described our said Invention and the manner of performing
the same we wish it understood that we Claim :-
First The above described mechanism for automatically stopping paper-bag
machines, the said mechanism comprising the angular piece or tappet m which,
when the paper is completely unrolled from the reel d, is moved outward from the
said reel by a spring and acts upon a set of levers, one of which is released and is

page_text: moved by the weight me so as to sound a signal bell and, at the same time,
transfer the driving belt from the fast to the loose pulley by means of the band or
belt-shifter m.
Second-The device u which clasps the paper, pasted from below, and throws
it by means of the nippers u¹, u¹, into such a position upon the table T that the
folding and sticking of the paper by means of the blades K¹, K², K³, K*, can be

Third The paper-folding and sticking apparatus, consisting of the blades
K', K2, K³, K, the blade K being provided with the spring-plate g¹ so that it will
be raised when the blade K³ is turned down to press against the pasted edge of
the paper, and the corner o of the blade K', by the backward movement of the
blade K with which it is connected, presses the corner S¹ of the pasted edge of
the bag against the underside thereof and thus makes a strong and durable point
to the bag.
Fourth-In combination with the paper-folding apparatus, the bag ejector y
which, at the moment when the blade K¹ lays the completed bag against its nipper,
is suddenly moved upwards by the mechanism x, y, so that the bag that has been
caught is struck off the point of the blade K', thrown against a receiving table S
and delivered from the machine.
Fifth. The mechanism for imparting to-and-fro motion to the blades K¹, K³, K³

and VI.
In witness whereof we the said Max Campe and Louis Campe have hereunto
set our hands and seals this Fourth day of December in the year of our
MAX CAMPE.
