COMPLETE SPECIFICATION.
A Machine for Producing Paper-packets from Flat Previously Cut
Sheets of Paper.
I, FRIEDRICH HESSER, of Ludwigsstrasse 61, Cannstatt, Wurtemburg, Machine
Maker, 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 a machine for producing paper packets from smooth
sheets of paper which are previously cut out to suit the folding of the packet.
The sheets of paper are superposed upon a block and are from thence lifted
off individually by a suction device; then in an intermittent forward motion, they
are successively conveyed to the different stopping places or stations where they
are treated, and they finally leave the machine is the form of ready-folded and
gummed paper packets.
At the first working station the sheets having been lifted off the block and
carried forward, are placed on a carriage, transported by the latter on to the
following station, retained there on a table by means of touching members, and
provided with an adhesive substance at the required places. At the subsequent
station the sheets are not worked upon. At the following station the sheet is
folded upon a pin or mandrel so as to form a sleeve, the said pin or mandrel
being mounted, in conjunction with a number of such pins or mandrels, upon a
disc receiving an intermittent motion. During the subsequent rotation of this
disc, at the respective stations, the sleeve is not further acted upon; then at the
following station the bottom is folded on to the sleeve and the folded bottom parts
are pressed on to the pin or mandrel. This operation of pressing the bottom parts
on to the pin is continued during the three subsequent part-rotations or during
the three subsequent stoppages, and in the then following station the paper
packet is knocked off the pin by an ejecting spindle, and discharged, the packet
dropping into a conveying channel and being collected in a receptacle.
A machine of this kind is represented in Figures 1 to 51 of the accompanying
drawings.
Figures 1 and 2 represent the whole machine in vertical elevation and plan,
respectively.
Figures 3, 4 and 5 represent two elevations and a plan of the device for lifting
off an individual sheet from the block and for transporting the same to the
carriage.
Figures 6, 7 and 8 illustrate, on a larger scale, the so-called suction device,
by means of which the sheet is sucked off the block.
Figures 9 to 13, illustrate the carriage for transporting the sheet and the
device for actuating the same.
Figures 14 to 19, represent in two elevations and a plan the apparatus employed
for transferring the adhesive substance to the sheet, whilst
Figures 20 to 23 shew a portion of the device by which the first folding of the
sheet is effected.
Figures 24, 25 and 26, are two different vertical elevations and a plan, of the
longitudinal folding apparatus, and
Figures 24, 24b, 28, 29 and 30 illustrate detail parts thercof. In the same

page_text: figures as well as in Figure 27 the mandrel disc and its working mechanism is
shewn.
Figures 31 and 32 represent the mandrels arranged on the mandrel disc, and
also a device for pressing the longitudinal fold of the paper packet.
Figures 33, to 43, Sheet.V1, illustrate those parts which are required for
producing the bottom fold upon one of the mandrels of the mandrel disc.
Figures 36 to 39, and Figures 42 and 43 shew devices and parts which are
required for pressing the folded bottom parts during the transport from the
bottom folder to the ejector.
Figures 44 to 51 represent the arrangement for actuating the pressing stamp
for the longitudinal folds for the paper packets, but on the mandrels of the
mandrel disc, and the apparatus for knocking off the paper packets.
The machine is worked by the main driving shaft 39 which by means of equally
large bevel wheels 42 works the transverse shaft 40 and shaft 41: Upon the
shafts 39 to 41 all the cams are mounted, by which all the moving mechanisms
with the exception of the gumming roller and the hand-actuated engaging and
disengaging mechanisms, and the pulley for actuating the mandrel disc are
operated. The shafts 39 to 41, and consequently all the cams mounted thereon,
rotate at the same speed. At each revolution of the main driving shaft the sheet
of paper or packet of paper, as the case may be, is transported from the preceding
to the subsequent station, in other words always one sheet is lifted off the block
and a finished paper packet discharged.
As can be seen from the figures of the drawings and as will be explained
further on, this operation in producing paper-packets is effected in the following
manner:
From the block of paper placed in angular guide ledges 2 first one sheet 1 is
removed by the suction stamp 3, which is fixed to a support 12 and communi-
cates with an air pump 7 by means of a tube or hose 5. This air pump is
actuated by a cam 6 in such a way that its plunger piston bears upon the said
camb through the intermediary of its guide roller 8 arranged thereon. At each
revolution of the cam bone sheet 1 is sucked up by the carriage 9 moving up and
down vertically in guide rods 10, this carriage being connected with an operating
lever 17 by means of the coupling link 16. The operating lever is located in a
support 19, fixed on the base-plate 36 of the machine and is worked by means of
the cam rod 18, from a cam a. On the vertically sliding carriage 9 rods 11 are
fixed, in which a support 12 is adapted to be displaced horizontally; on this
support the suction stamp 3 is fixed and the support receives its horizontal motion
by means of a link 13 from an operating lever 14, which is actuated by a cam c
mounted on the shaft 40. On the support 12 moreover a sheet-applying-pin 6 is
mounted which facilitates the lifting off of a sheet by being located slightly lower
than the suction stamp 3, thereby causing in its descent and application to the
paper block, the said block to be slightly bulged under the suction stamp and thus
facilitating the suction effect and the removal of the sheet.
Thus at the first station, the sheet of paper is sucked and lifted off the block
and a horizontal forward movement imparted to it from the block to the carriage.
For re-adjusting the paper block there is provided a rack bar 25 guided below
the block in a guide support 24 and screwed on to the supporting plate 26 of the
block; with this rack bar gears a small toothed wheel 27, mounted on a shaft 28
on which also a ratchet wheel 29 is fixed, which is moved intermittently, by a
pawl 31 connected with the lever 17 by means of a red 30; the ratchet wheel
being secured against return motion by a counter pawl 32. The counter pawl 32
is retained in permanent engagement with the ratchet wheel by means of a
spring 33 fixed on the arm 34 (Figure 4). In order to prevent the lifting-off of
a sheet from the block while the machine is working, a stopping device is pro-
vided, consisting of a lever 20 furnished with a stop-pin 21; this lever with its
pin 21 can be so turned under a projection 22 arranged on the carriage 9, that
the latter is prevented from descending sufficiently to apply itself with its suction

page_text: stamp against the paper block. A spring 23 arranged on the lever 20 retains the
lever in its momentary position.
In order that the block may be displaced directly, if so required, a small
hand wheel 35 is in addition provided upon the shaft 28 of the ratchet wheel
(see Figure 3).
The sheet 1 transported from the first station to the first stopping place upon
the carriage 43, is now transported by the latter in co-operation with the trans-
porting device, represented in Figures 9 to 11, to the second station. This is
effected from the cam h by the carriage being connected by a piece 45 and a
coupling link 46 with the carriage-operating-lever 47, the cam h communicating
its motion to the cam rod 48 which is coupled with the lever 47. During this
operation the sheet 1 rests against the stops 58 of the carriage 43, and is during
its transport, securely held in its proper working position upon the transporting
table 59, at the respective station, by means of angular stops 55 traversing the
transporting table and fixed on elbow levers 54, which angular stops retire be-
neath the table plate 59 when the carriage is moved back. The elbow levers by
means of small supports 56, are rotatably arranged beneath the table and, by
means of the common rod 53 and the connecting rod 52, are connected with the
operating lever 50, which is actuated by the cam mounted on the shaft 40,
by means of the cam rod 49 (Figures 9 and 10). As the carriage 43 moves for-
ward the angular stops project from underneath the table 59, thus stopping the
forward movement of the sheet.
The sheet 1 is retained at the station II upon the table 59 by a finger plate 65,
which is vertically adjustable by means of its rod, and is jammed into the split
socket of the end of a freely rotatable lever 64. The lever 64 is adjustably
secured between the screws of a lever 66 and of an angle 67 fixed thereto
(Figures 15 and 16). Of these two levers 64 and 66, the one is mounted loosely
and the other rigidly upon a shaft 60 located in the support 61, upon which shaft
also the operating lever 62 for the finger plate is fixed. The lever 62 is actuated
by the cam by means of the cam rod 63 loaded with a weight.
At the station II the sheet 1 is provided with adhesive substance and for this
purpose the gumming apparatus, shewn in Figures 14, 15 and 16 is provided,
the exchangeable gumming stamps 88 and 89 of which are represented on a
larger scale in Figures 18 and 19 in vertical elevation and plan. These gumming
stamps are held by their rods vertically adjustable and exchangeable on a stamp
support 87, which by means of its circular pin is inserted in a support 85 and is
secured in its position by means of a pin passed through both (Figure 15). The
two gumming stamps are provided with fresh adhesive substance after using,
that is to say, are always first passed to the gumming receptacle and then to the
place of use. This is effected in the following manner: The support 85 is so
arranged as to be horizontally movable on horizontal rods 86, which are screwed
on to a support 71, arranged so as to be vertically movable on rods 72, which
latter are screwed to the base plate 36 of the machine. This support 71 is lifted
and lowered by a rod 74 connected therewith and which is mounted on a
lever 75; the lifting and Towering being effected by a cam d, upon which the
lever 75 bears by means of a roller 76.
With the support 71, the guide rods 86, serving to move the support 85 in a
horizontal direction, also move up and down vertically. This support, by a
thrust rod 79, fixed thereon, is connected with the slide 80 of a lever 81, which,
being pivoted in the bearing support 82, is pulled to its came by a spring 83
held by a pin 84, and is actuated by the cam. The slide 80 is mounted, below,
upon the angular piece 77 fixed on 71, and the said angular piece jointly serves
for guiding the support.
In the vertical movement of the support 71, it will be observed that its lower-
ing is effected in two steps. During the first step the support descends to such
an extent that in the course of the horizontal motion the lower surfaces of the
gumming stamps 88 and 89 pass over a rotary gumming roller 90, which is

page_text: located in the gumming trough 91 and constantly rotated by belt gearing by
means of the pulley 93 mounted on the roller shaft 92, and by the double
pulley 94 located in the bearing support 96, the rotation taking place from the
driving pulley 95 mounted on the shaft 39. After the stamps 88 and 89, thus
provided with adhesive substance, have reached the end of their horizontal
motion, the support 71 descends entirely and transfers the adhesive substance
to the sheet, which is retained by the fingers 65, so as to prevent the sheet from
being lifted by the re-ascending stamps. The lifting of the support 71 does not
take place in steps but in one stroke from the lowest to the highest position.
If, for any reason, it is desired that no adhesive substance should be applied
to the sheet, a lever 97, connected by a rod 98 with a stopping pawl 99, is thrown
into action, that is to say, so displaced, that the pawl engages with the ratchet
teeth 100 of the support 71, thus preventing the latter from descending. The
gumming stamps then of course continue their horizontal motion but no longer
descend and therefore do not transmit any gum to the sheet.
The sheet, then provided with adhesive substance, is transported by the
carriage to the third working station, where it is retained upon the table in the
same manner as at the second station, solely by a finger plate 70 by means of
levers 69 and 68 mounted on the aforesaid shaft 60. The adhesive substance then
has an opportunity of slightly drying, whereby consequently a more effectual
pasting is obtained.
From the station No. III the sheet is conveyed by the carriage 43 on to the
folding box 101, specially shewn in Figures 20 to 22 on a larger scale, but also
illustrated in Figures 14 and 16. When this vertically displaceable folding box
is in resting position it lies above flush with the table 59 and the carriage 43;
it has a slot or recess 102 similar in cross section to the outer cross-section of
the paper packets; this slot or recess lies directly below a mandrel or pin 115,
eight of which are fixed, at regular intervals on a disc 118 moved intermittently
to the extent of one eighth of a revolution. When the folding box 101 is moved
upwards one mandrel or pin 115 of the disc 118 places itself in the recess 102.
The sheet 1 is thus first folded in U-shape. For lifting and lowering the folding
box 101, the same is located by means of its supporting rod 103 in a support 104,
a guide arm 105 being fixed on the supporting rod, the free end of which guide
arm 105 is guided on an angular piece 106 and the object of which is to
prevent the folding box 101 from being turned. The arm 105 communicates
by the connecting link 107 with the operating lever 108 of the folding box
which receives its motion from the cam g on the shaft 41.
In the folding box 101, to one side of its supporting rod 103, and parallel to
the latter, a rod 111 is arranged which is held in a certain position (as indicated
in Figure 20) by a spring 112 and an adjusting ring 114. This rod carries at
the top a plate 111* exactly fitting and located in slot 102 of the folding box.
This plate serves to retain the sheet 1 on the mandrel or pin 115 during the
folding, so that the sheet can not become displaced on the said pin. On the
ascent of the folding box and during the folding, the plate 111 carries up and
presses the sheet on to the mandrel or pin 115 (Figure 14) so that the plate 111°
cannot move up further whilst the box 101 continues to ascend until the
plate 111 is in the bottom of the slot 102 of said box. When the folding box
re-descends, the plate 111 is still pressed against the mandrel 115 by the
spring 112 acting on the rod 111 until its adjusting ring 114 is engaged by the
base of the box. The plate 111* thus presses the paper 1 on the mandrel 115
during the folding and enables the paper tube thus folded to easily leave the
slot 102 of the folding box when the latter descends.
The sheet drawn up round the pin 115 by means of the folding box 101 is
then folded upon the pin or mandrel by the device represented on Sheet V. For
this purpose folding slides 138, 139 and 140 are arranged in the following manner
in a frame 126 fastened like a bridge on the base plate 36. The folding
slides 138, 139 are fixed to doubly bent arms 130 (Figure 25) which in turn are

page_text: rigidly mounted on carriages 129, which are movably arranged in carriage-sup-
ports 127 rotatably secured on the frames 126 by means of pivots 128. The
carriages 129 are placed symmetrically above the folding box and above the
mandrels at both sides and are actuated in the carriage guides 127 by means
of coupling links 131 from the bell crank levers 132 located in the frame 126
and which are operated by the weighted rods 133 through the cams and k
mounted on the shafts 39 and 41. The two pivoted carriage guides 127 have
their free ends jointly connected with an operating lever 135 by connecting
rods 134, which lever 135 is located upon a carrying support 137 and is actuated
by a rod 136 from a cam i.
In producing the longitudinal fold the carriage-guides 127 are first lowered
by the lever 135 until the folding slides 138 and 139 arrive at approximately
the same height as the top surface of the folding mandrel 115. The carriages 129
then commence their movement in such a manner that first the folding slide 139
folds down that portion of the sheet which projects upon one side above the
mandrel, the operation being, however, such that the folding slide 139
only extends beyond the folding edge of the mandrel 115 about 1
to 1 millimetres, while the more rapidly moving auxiliary folding
slide 140 located above the slide 189 and which is actuated by a bell
crank lever 142 connected therewith by a connecting rod 141, and operated by a
rod 143 (Figure 24ª) from a cam 1, completes the folding at this side. Mean-
while also the folding slide 138 has started its movement upon the other side and
folds the gummed portion of the sheet over the already folded part thereof, in
which operation the auxiliary folding slide first returns rapidly in order not to come
in contact with the adhesive substance, whilst the folding slide 139 pressing, but
slightly against the mandrel returns simultaneously with the folding slide 138.
The folding slides then are again lifted by the lever 135 and the just pasted down
longitudinal side of the paper packet is immediately pressed by the pressing
plate 121 movably located above the mandrel 115, (Figure 31) which pressing
plate may be provided beneath with a rubber facing. The pressing plate 121
is pivoted on a lever 120 movably located in lugs 119 on the mandrel disc 118,
and is applied against the mandrel by a spring 123 placed round the pivot 122
and acting upon the lever.
On the mandrel-disc 118 eight mandrels 115 are arranged which are inserted
in eyes of the pin disc and are removably secured by binding screws. Each of
these eight mandrels has a pressing plate 121 each of which is applied against
the mandrel by a spring 123 acting upon its lever 120. (Figures 31 and 33.)
Always at two mandrels of the mandrel disc 118, namely where the longitudinal
fold is produced by the folding box, and where the finished paper packet is
knocked off the mandrel, it is necessary that the pressing plates 121 be lifted,
in order that the said operations can be carried out. This is effected by a
sleeve 204 so arranged on the shaft 125 of the mandrel disc as to be vertically
displaceable but not rotatable thereon, (see Figures 44, 46 and 47) and on which
sleeve two noses 205 are arranged laterally and projecting downwards. These
noses are located above the free ends of those of the levers 120 which actuate
the corresponding two pressing plates 121. The sleeve 204 is engaged by the
fork of a lever 206 which is fulcrumed on an intermediate piece 208 which
is pivoted on the support 209, said lever being actuated by the rod 207 from a
cam u (Figure 47). After each partial rotation of the mandrel disc 118 the
sleeve 204 is lowered by the lever 206, and those of the levers 120 for the time
being at the longitudinally folding and knocking-off stations, are depressed and
the pressing plates 121 moved up from the respective mandrels.
The intermittent rotation of the mandrel disc 118 is effected by a notched
disc 147, mounted on the mandrel-disc-shaft 125 and provided with eight slots
or notches 148, which are engaged by a crank 150 which is mounted on a
shaft 152 and the crank pin of which, engages with one of the slots or notches 148
of the disc 147 and turns the latter exactly one eighth of a revolution. The

page_text: absolutely accurate adjustment of the notched disc 147 and of the mandrel disc 118
respectively is effected by a pin 160 which is movably mounted in a long
socket 159 and the upper pointed end of which engages in one of the eight
eccentrically placed sockets 203 which are arranged on the mandrel disc at
exactly uniform intervals (Figures 25 and 26). The pin 160 is connected by a
link 161 with a bell-crank lever 162 pivoted in a support 164, and actuated by
the rod 163 from a cam m. During the rotation of the mandrel disc 118: the
pin.160 is drawn out of its engagement with one of the sockets 203 (Figures 25
and 26).
The two shafts 125 and 152 are respectively mounted below upon a transverse
piece 149, screwed to the frame 37 of the machine, and on an arm 153 of the
transverse piece, and are guided above by the sleeve 145 and the support 154
respectively.
The shaft 152 is driven from the main driving shaft 39 of the machine, by
means of the pairs of bevel wheels 156 and 155 (Figure 24), one wheel of each
pair being mounted on a shaft 157 located in the support 158.
The paper sleeve produced from the sheet at the station IV is still on that
mandrel of the mandrel disc on which it was folded and pasted and it is not
further operated on at the following station V only the pasted side being
. retained by the pressing plate 121.
From the station V the paper sleeve still on the mandrel arrives at station VI,
where the bottom is folded (see Sheet VI). At this station four bottom folding
slides 166, 171, 177 and 185 are movably located in the form of a cross on a
vertical plate 165. The upper and lower bottom folding slides 185 and 177
(Figure 34) are actuated simultaneously, the one by a lever 187, coupled with its
carriage 186, and operated by a rod 188, from the cam q, and the other by its
carriage 179 and the connecting piece 182, connecting the said carriage with a
lever 183, operated by a rod 184 from the cam p.
During the upward movement of the lower bottom folder 177 which is pivotally
mounted on its carriage 179, this bottom folder strikes with its lower part against
an angular piece 181 whereby the folder is firmly applied against the bottom of
the paper packet. As this folder recedes, it is forced off the bottom of the paper
packet by a spring 180 (Figure 40).
The pivotal arrangement of the lower bottom folder is necessary because the
paper there must be folded over the narrow side of the mandrel before the
broad side is folded, in which latter operation the folding slide encounters a
strong resistance. Upon the narrow upper surface of the mandrel, where the
upper folding slide operates, the paper is still soft owing to the application of
the paste or gum and can be more easily folded, and for this reason an ordinary
folding slide is here used.
After the receding of the two folding slides 185 and 177, the slide 171 fixed on
the carriage 172 (Figures 33 and 35) will, under the action of the cam o the
rod 175, the bell-crank lever 174, and link 173, fold down the last pasted or
gummed broad side of the bottom, after the folding slide 166, whose carriage
167 is moved by a lever 168 operated by the rod 169 from a cam n, has pre-
viously folded down the other broad side of the bottom.
The folding slides 185 and 177 are returned to their normal position by the
weight of the driving mechanism, the folding slide 171 by the weight placed on
its cam rod, and the folding slide 166 by a spring 170 acting on its cam rod 169.
Immediately after the last folding slide has returned, that is to say, has moved
away from the bottom of the paper packet a lever 193 (Figure 39) likewise
pivoted on the support 189 (Figures 33 and 34) is actuated by a cam r; this lever
presses a pin 191 with its pressing plate 190 against the paper bottom the said
pin being movably mounted in the support 189. Before the mandrel disc 118
is further moved the lever 193 again releases the pin 191 together with its
pressing plate 190 and the spring 192 wound on the pin 191 forces back the pin
and its pressing plate 190 (Figures 34 and 39).

page_text: During the three subsequent movements of the mandrel disc 118 the finished
paper packet lying on the mandrel successively arrives at the stations VII, VIII,
and IX, where no further treatment properly speaking takes place but only
the bottom of the paper packet is pressed against the end of the mandrel 115,
preferably by a plate provided with an elastic facing.
At the stations VII and IX this pressure is for instance effected by levers 194
located at the corners of the machine and pivoted in supports 195; these levers
being connected with operating levers 198 pivotally secured in bearings 200
(Figures 36 and 37) by means of adjustable or fixed coupling pieces 197 and 197"
(Figures 42 and 43); the said levers 194 are actuated by cams s and s¹ bearing
with their inclined surfaces against the guide rollers 199. The levers 194 are
returned to their normal position by springs 196 during the shifting of the
mandrel disc. The pressing of the bottom of the paper packet against the
mandrel 115 at the VIIIth station is effected by a cam t mounted on the shaft 40,
by means of a weighted rod 202 and a bell crank lever 201, which is pivoted on
the support 263 and carries at its front a pressing plate (Figure 38).
From the IXth station where the bottom of the packet was pressed as described
the paper packet still on the mandrel arrives at the station X that is, the so-
called ejecting station where the packet is knocked off the mandrel and dis-
charged.
This ejecting device is represented in Figures 44 to 51 and in Figures 31
and 32. In each mandrel 115 a rod 116 is movably located, which has a small
plate 117 at its front, which plate is completely flush with the front surface of
the mandrel 115. On the rear end of the rod 116 a guide piece 124 is secured
by a set-screw, which piece engages with its upper part in a radial slot in the
mandrel disc 118 and thereby prevents the rod 116 and small plate 117 from
turning. The lower part of the guide piece 124 lies in an annular groove
between the hub and the edge of a sleeve 145, so that as the mandrel disc turns
with its mandrels 115, the rods 116 of the mandrels cannot become displaced
vadially.
At one place however where the paper packet is to be knocked off the mandrel
(see Figures 47 and 49), the rim or crown of the sleeve 145 has a recess 146. In
this recess 146 the hook-shaped end 211 of a rod 210 is placed, which is movably
located in supports 215 and 216, and in the hook 211 of which rod is placed the
lower end of the guide piece 124 of that rod 116 from whose mandrel the
finished packet is to be ejected. Immediately after the mandrel stops, the hook
rod 210, which is coupled with a lever 214 by a clamp piece 212, fixed on the
said rod 210 and by a link 213 is displaced by a cam v acting on said lever 214.
The rod 210 carries along with it the ejecting rod 116 placed in the mandrel 115,
and the packet is thus drawn off the mandrel. Before the ejection of the packet
commences another pressing plate 218, fixed on the rod 219, is applied against
the end of the mandrel, or rather against the small plate 117 of the pin 116, by the
levers 220 actuated by a rod 221 from the cam Z, so that the bottom of the packet
or bag during its ejection lies between the plate 117 and the pressing plate 218,
upon the rod 219, which latter is like-wise located in the support 216. In order
that the lever 220 in receding may offer a certain resistance, whereby the bottom
of the packet will be firmly gripped between the plates 117 and 218 until the
ejection has been completed, the lever 220 is coupled by a pin 230, with a brake
segment mounted on the same axis therewith, this segment turning with the
pin, and upon which segment there bears elastically a brake block 227 by a
lever 223 by means of the cam y and of a spring 226, located between the block
and lever, (Figure 48). The lever 223 presses upon the cam y with its slide-
roller by the action of a weight 224 arranged on the lever and the latter is located
on a support 222 which like the levers 220 and 214 is located upon a support 217
screwed to the frame 37 of the machine (Figure 49). As the support 217 pro-
jects to some considerable extent, a strong supporting set screw 268 (Figure 44)
bearing upon the bottom, is arranged for strengthening the support.

page_text: The spindle 225 of the aforesaid brake block 227 around which spindle the
brake spring 226 is placed, carries below as shown in Figures 44 and 48, a guide
piece 228 which can slide in a slot in the support 222.
After the packet has been ejected from the mandrel, the ejecting rod 116 is
again returned by the hook rod 210, and the packet lies freely upon the upper
side of a bent piece or bracket 237, which adjoins an oblique discharge channel 243
(Figure 45) fixed on an angular support 244. For throwing the paper packet
from the upper surface of the bracket 237 into the discharge channel 243, the
device shewn in Figures 50 and 51, which is actuated in the following manner,
is employed. In order to prevent the paper packet which, after having been
knocked off the mandrel, lies with its narrow side upon the bracket 237, from
falling over, a flap 232 is hinged on a pin 231, which flap carries a roller 233,
which engages in a slot in a lug 234 which is fixed on a movable arm 235. At
the bottom of this arm an angular piece 236 is so fixed that the packet lies be-
tween 236 and 237. After the ejecting rod 116 has receded, the arm 235 which
is fixed by an angular piece 238 on a sliding rod 239 (Figure 45) is moved to and
fro by the coupling rod 240 which links the sliding rod 239 to a lever 241,
actuated by a cam c on the shaft 40. The spring 242 keeps the lever 241 in
constant engagement with the said cam. When the lever 241 moves from the
position drawn in solid lines, into that represented in dotted lines (Figure 45)
the arm 235 with the angular piece 236 and the lug 234 is likewise displaced,
but simultaneously also the flap 232 is rotated so rapidly by the lug 234 that the
paper packet has ample space for dropping into the channel 243. On returning
to their normal position the angular piece 236, the lug 234 and the flap 232
again occupy the position shewn in full in Figure 51.
During the further turning of the disc 118 the mandrel 115 freed from its
paper packet, arrives at the station XI where no operation takes place and during
the subsequent rotation of the disc the mandrel again presents itself above the
folding box 101, where the operation re-commences.
The machine is driven by the belt pulley 245 (Figures 1 and 2) which can be
thrown into and out of action in an ordinary manner by a segment clutch coup-
ling 247.
For engaging and disengaging the said clutch 247 the same is directly
connected with a lever 248 coupled by a link 249 and a lever 250 with a shaft 251
on which there is also mounted another lever 252, the levers 250 and 252 being
located at different places of the machine so that the engagement and disengage-
ment from any place can be effected rapidly. For testing the machine by hand,
a hand wheel 246 is arranged on the driving shaft. The pulley 245 is mounted
on the driving shaft 39 which, as well as the shafts 40 and 41 is located in bearings
on the frame 37. All eccentrics a to z are mounted on these three shafts which
are rotated at uniform rates of revolution by the pairs of bevel wheels 42.
At each revolution of the shaft one paper packet is finished so that conveniently
some 20,000 to 25,000 paper packets can be produced per day with one machine.
By exchanging the mandrels 115, folding boxes 101 etc., paper packets of any
suitable size can be produced by the same machine.
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. A machine for producing paper packets from previously cut sheets of paper,
the characteristic feature being that the individual sheet of paper is lifted off
the block by means of a suction device, then transported upon a carriage, and
thence after the application of adhesive substance-folded in the form of a
sleeve above one of the folding pins or mandrels arranged on a disc receiving an
intermittent motion, and glued or pasted, and that upon the further part rota-
tion of the disc and after the folding down and pasting together of a sheet and
after its being pressed against the mandrel by means of pressure plates during

page_text: the period elapsing between the passing of several stations, the finished paper
packet is drawn off the mandrel and deposited by an ejecting spindle actuated
by an ejecting device.
2. In a machine of the kind described in the first claim, a suction and trans-
porting device for the sheet of paper (1) consisting of a suction stamp (3) con-
nected by a tube (5) with an air pump (7) the said stamp being arranged on a
support (12) horizontally displaceable in rods (11) by a cam (c) a lever (14) and
connecting rod (13) and being actuated by fixing these rods (11) to a second
support (9) movable vertically by a cam (a) through a rod (18) lever (17) and
link (16), and the block of paper being held in upward position by the latter
lever by the aid of a slotted lever (31) coupled therewith, a pawl (30) a ratchet
wheel (29) and a pinion (27) in co-operation with the rack bar (25) supporting
the block of paper.
3. In a machine of the kind described in the first claim, for transporting the
sheet of paper (1) up to the mandrel disc, a device consisting of a carriage (43)
travelling by means of rollers (44) upon the base plate (36) of the machine, this
carriage being set in reciprocating motion from a cam (h) through a rod (48)
and lever (47), and transporting the sheet of paper (1) placed thereon by the
suction device, by means of its noses (58), the sheet, being retained at the
stations by finger plates (65 and 70) upon the transporting table (59), these
finger plates being moved by a cam (f) by means of a lever (62) operated by
said cam and levers (64 and 68 respectively) which carry said plates; angular
stops (55) being fixed on rotatable elbow levers (54) below the transporting table
for the purpose of placing the sheet in correct position, these elbow levers being
so actuated from a cam (¹) by a rod (49) and lever (50) that the angular
stops (55) project above the table when the carriage advances, thus forming a
stop for the sheet, but on the contrary retire below the table when the carriage
recedes.
4. In a machine of the kind described in the first claim a device for applying
the liquid adhesive substance upon the sheet of paper, this device consisting of
a number of paste-applying-stamps which are exchangeably and adjustably fixed
on a supporting plate (87) which is so arranged on a sliding support (85) hori-
zontally movable on rods (86) by means of actuating rod (79), lever (81) and
cam (e) as to be easily removable and which is retained by a pin; the slide
rods (86) being fixed to a vertically sliding support (71) which is moved down in
two steps by a cam (d) lever (75) and supporting rod (74), the operation being
such that during the first step when the pasting stamps move in a horizontal
direction the lower surface of these stamps pass over a rotary gumming roller (90)
located in a gumming trough (91), thus receiving an adhesive substance and trans-
mitting the same, at the termination of the horizontal motion, to the sheets of
paper as they move further down.
5. In a machine of the kind described in the first claim, for folding the flat
sheet of paper (1) first in the form of a sleeve, a device consisting of a vertically
displaceable folding box (101), the top of which, when in its normal position, is
flush with the table (59) and which, by a cam (g) a lever (108) a link (107) and
arm (105) is coupled with the supporting rod (104) of the folding box and is
lifted together with the pasted sheet lying above, and the latter by one of the
mandrels (115) which are arranged on a disc (118) and which lies above the
folding box, is pressed into a slot or recess (102) in the folding
box, and the parts of the sheet thus projecting above the mandrel and
box are folded down by means of vertically liftable and horizontally displaceable
folding slides (138) and (139) by the aid of an auxiliary folding slide (140); the
lifting and lowering of the carriage guides (127) which are rotatably arranged
on a bridge support (126) on pivots (128) and which carry the folding slides
which are fixed by doubly bent arms (130) on a carriage (129)-being effected
from a cam (i) by means of a rod (136) lever (135) and coupling links (134):
and the horizontal displacement being effected by means of rods (133) bell

page_text: crank levers (132) and the links (131) which connect the latter with the
carriage (129); the first-acting folding slide (139) advancing only so far as to
hardly extend beyond the folding edge, whereas the more rapidly travelling
auxiliary folding slide (140), located directly above the same and worked by a
cam (7) by means of a rod (143), lever (142) and connecting rod (141) rapidly 5
folds down the one side of the paper, and again returns before the pasted side is
folded over it, whereupon both slides (138) and (139) uniformly recede and are
re-lifted.
6. In a machine of the kind described in the first claim the arrangement of a
disc (118) provided with a number (8 for example) of mandrels (115) arranged
at equal angular distances and centrally; this disc being moved intermittently
at equal part rotations by a notched disc (147) arranged on the same shaft (125)
therewith; a crank shaft (152) being for that purpose provided, the crank (150)
of which engages by its pin (151) with one of the eight slots or notches (148) in
said disc, thus moving the latter and therewith the mandrel-disc (118) to the
extent of one-eighth revolution, the exact adjustment of the mandrel disc being
effected by a pin (160) pointed at its top and moved up and down by means of a
cam (m) and bell crank lever (162); this pin being guided in a sleeve (159) and
engaging with one of eight sockets (203) and equalising any slight irregularities
in the intermittent rotary motion of the dise; and a pressing stamp (121) which
may be covered below with a soft material, being movably arranged on a
lever (120) depressed by a spring (123) for pressing the pasted down longitudinal
sides of the sleeves or packets still on the mandrels (115), while for the mandrels
situated above the folding box, or located at the ciccting station. the levers (120)
thereof are depressed by the noses (205) of a sleeve (204) located on the mandrel-
disc-shaft (125), and displaced by means of lever (206) rod (207) and cam (2)
so that the packets are not pressed or held by the pressing stamps.
7. In the machine of the kind described in the first claim, for folding the
bottom of the sleeve or packet held in position on a mandrel of
the mandrel disc a device consisting of four folding slides (166),
(171), (177) and (185) arranged crosswise and guided in a carriage, the upper
and lower folding slides working simultaneously, and the carriage (186) of the
upper folding slide being actuated by means of a cam 7 a rod (188) and lever
(187) and the carriage (179) of the lower folding slide by another cam (p)
rod (184) and lever (183), the lower folding slide (177) being pivotally arranged
on its carriage and being fully pressed with its working surface against the
bottom of the paper parcel but not until having nearly completed its stroke, this
pressure taking place by the slide (177) striking against an angle (181) where-
upon the right folding slide (166) on its carriage (167) is actuated by a cam (n)
rod (169) and lever (168) and the last slide (171) by means of a lever (174)
rod (175) and cam (o) folds down the pasted side, whereupon, immediately a
pressing plate (190) is applied by means of a lever (193) and cam (r) against
the bottom just finished.
8. In a machine of the kind described in the first claim, for pressing the bottom
of the paper packet against the mandrel, at the stations VII, VIII and IX, the
arrangement of pivoted levers (194 and 201 respectively) which being worked by
rods (198 and 202) from cams (s and s) will during the period of rest at these
stations, apply their pressure plates against the bottoms of the sheets, said levers
being returned to the inoperative position by springs (196) and by a weight on
one cam rod (202).
9. In a machine of the kind described in the first claim, the arrangement, at
the station X for ejecting the completed paper packet from the mandrel, of a
device consisting of ejecting rods (116) arranged displaceably but not rotatably
in each mandrel (115) of the mandrel disc (118) the front ends of these rods being
widened in the form of plates (117) and being located exactly level with the
respective end surfaces of the mandrels, and at the rear ends of which rods, guide
pieces (124) are screwed, which, being guided above in radial slots of the

page_text: manchel disc prevent the ejecting rods from rotating, and which during rotation
of the mandrel disc (118) slide with their lower ends in an annular groove of a
sleeve (145) so that a displacement of the ejecting rods only at the ejecting station
is rendered possible by the arrangement of a recess (146) in the wall of the groove
at that place, by which recess the hook-shaped rear end (211) of a rod (210)
worked by a cam (r) and a lever (214) is already prior to the arrival of the eject-
ing rod (116) so introduced into the sleeve (145) that the lower end of the guide
piece (124) is located in this hook and that during the forward motion of the
hooked rod (210) the ejecting rod (116) is jointly carried along, the operation
being such that by a pressing plate (218) mounted on the end of a rod (219)
moved by a cam (2) and lever (220) the bottom of the paper packet is firmly
Dressed between the pressing plate and the plate of the ejecting rod, the lever
(220) being coupled by a pin (230) with a brake-segment (229) which is efficiently
braked during the ejection of the paper packet by a brake block (227) actuated
by a cam (y) lever (223) and a spring (226).
10. In a machine of the kind described in the first claim, for discharging the
paper packet ejected from the mandrel, a device consisting of a displaceable
arm (235) actuated by a cam (w) lever (241) coupling piece (240) and sliding
rod (239) and connected with the latter by an angular piece (288) which angular
piece moves the paper packet loosely lying upon the plate of the rail (237)˜ into
an oblique discharge channel (243) while a hinged flap (232) which during the
pushing out of the paper packet is placed laterally adjacent to the parcel and
which turns on a pin (231) is rapidly opened by a lug (234) fixed on the arm
(235) and engaging with its slot over a roller (233) mounted on the flap, so that
the paper packet can be laterally discharged.
11. For producing paper packets from previously cut sheets of paper, a
machine constructed and operating substantially as described with reference to
the accompanying drawings.
