A Packing and Wrapping Machine.
I, GEORGE BARKER, Fellow of the Chartered Institute of Patent Agents, of
77, Colmore Row, Birmingham, in the County of Warwick, Consulting
Engineer, do hereby declare the nature of the said invention as communicated
to me from abroad by The Economy Packing Machine Co., of 33, Broad Street,
in the City, County, and State of New York, United States of America, and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
My invention relates to a machine for packing and wrapping measured
portions of fibrous material in rectangular packages, applying suitable labels
thereto and printing thereon such words and devices as may be required.
One of the objects of my invention is to provide means for severing from a
continuous web or webs of wrapping material a sufficient quantity to form a
wrapper, which wrapper is carried by suitable means to mechanism adapted to
form it into a U-shape. after which the measured quantity of material to be
packed, as tobacco, is emptied into the U-shaped wrapper. Suitable devices
are thereafter brought into operation to pack the material while in the U-shaped
wrapper, fold the wrapper around the material, close the ends, and carry the
completed package to a collecting device, when it is deposited with others in
regular order in a box placed in position to receive the product of the machine.
Another object of my invention is to provide a device for automatically
attaching labels to a continuously moving web of outer wrapping material, at
such distances apart, that they shall each be in the center of a severed wrapper.
I have also arranged on the machine a printing press for the purpose of printing
the necessary words and devices on the labels or on the wrapper direct when
labels are not used.
Another object of my invention is to provide suitable mechanism for folding
the wrapper around the material in such manner that the corners of the package
shall be sharp and square, a result which, as far as I am aware, has not been
heretofore accomplished.
A further object of my invention is to make the machine self clearing, each
part with which the material comes in contact being cleaned by the scraping or
rubbing action of a subsequently moving part, thus avoiding the necessity for
frequent inspection and manual cleaning to prevent clogging. This is highly
important in packing and wrapping tobacco containing a large percentage of
casing or foreign matter.
In the fuller description of my invention and its objects, reference must be
made to the accompanying drawings, in which
Figure 1 is a plan view of my improved packing and wrapping machine.

Similar numerals of reference indicate similar parts in the various figures.
In describing the machine, the side at which the operator stands is called the
front, and the opposite side the rear; what is on the right hand of the operator
being called the right of the machine, and what is on the left hand, the left.
To a suitable base 1 resting on the floor are bolted legs 2, 2ª and 2 on the
tops of which a bed-plate 3 carrying the packing and wrapping mechanism is
supported. Journaled in suitable brackets at the rear of the machine is a main
driving shaft 4 extending lengthwise thereof in a horizontal direction. A
driving pulley 5 is adapted to rotate freely on the shaft 4: but it may be locked
thereto by means of a clutch 6 operated by a handle 7 extending across and above
the bed plate, which is fixed to the upper end of a vertical shaft, whose lower
end carries a fork spanning the clutch 6, as shown in Figs. 1 and 2. The clutch
and handle may be placed in other position if found more convenient. On the
main shaft 4 is keyed a fly wheel 8 and a pinion 9, which latter meshes with
and turns a spur wheel 10 fixed to a secondary shaft 11 journaled in bearings
bolted to the bed, as indicated in Figs. 1 and 2. Various cam wheels, herein-
after described, are keyed on the shaft 11.
Rotating in bearings on the legs 2 at the left end of the machine, is a shaft 12
which extends at a right angle to the shaft 11 but in a higher plane. These two
shafts are geared together by means of spiral toothed wheels 13, 14, of equal
size, (Fig. 1). The shaft 12 also carries various operating cams which will be
hereinafter described.
A shaft 15 parallel to the shaft 11, and adapted to turn in bearings projecting
from the bed-plate 3, is driven from the shaft 11 by means of the engagement
of a gear wheel 16 mounted thereon, with an intermediate gear 17, which in
turn meshes with a gear 18 on the shaft 15. The gear wheel 17 is journaled on
a bar 19 having a bearing at each end within which the shafts 11, 15 turn. The
gear wheels 16. 18 being of the same size, the shafts 11, 15 will rotate at the
same speed.
Beveled gear wheels 20, 21 fixed on the shaft 15, engage with beveled gear
wheels 22, 23 of similar size on the shafts 24, 25, respectively, which extend
cross-wise of the bed-plate 3, as shown in Figs. 1, 23. 21 and 22. It is to be
observed that the several shafts above described, with the exception of the
driving shaft 4, make one revolution to complete that cycle of operation whereby
one complete package is produced. The driving shaft 4 makes three revolution's
to one of the other shafts, but this proportion may be changed to agree with
the speed and power of the prime motor.
Brackets 26 (Figs. 2 and 21), bolted to the outside of the legs 2b, are provided
with open bearings within which the shaft of a continuous roll 27 of wrapping
material 28 turns. This wrapping material consists preferably of a web of
paper cemented to a web of metal foil, although separate webs of paper and foil
may be used, as will be hereinafter shown. From the roll 27, the web 28 of

page_text: compound wrapping material passes over an idle roller 29 and the bed-plate
to a pair of drawing rolls 30, 31, mounted in adjustable bearings of ordinary
form, by. means of which the web is drawn with regular and continuous move-
ment from the roll 27, and fed to an intermittently operating knife 32, which
cuts from the web at regular intervals a length sufficient to form a wrapper.
The rolls 30, 31, geared together as shown, are rotated by means of a pinion 31ª
(see Figure 22) on the cross shaft 24 meshing with the gear wheel on the lower
roll 31. The pinion 31 makes two revolutions to one of the rolls 30, 31, as. the
circumference of each roll is equal to the length of two wrappers. Ribs 30
(see Figure 1) on one end of the roll 30 crease the wrapper to facilitate the
folding operation.
The knife 32 is pivoted at 33 to a bracket bolled to the rear side of the bed-
plate 3. and extends across the web of wrapping material to the front side of
the bed-plate where its end is connected by means of a link 34 to one arm of an
elbow lever 35 pivoted to the bed-plate. The other arm of the elbow lever.
carries a roller 36, which bears on the periphery of a cam wheel 37 mounted on
the cross shaft 24, by means of which and a spring 38 acting against the lift of
the cam, the knife is operated. Extending across the bed-plate in close proximity
to the knife, is a bar 39, over which the web of wrapping material passes and
with which the knife coacts to sever the wrapper. The bar 39 is raised a short
distance above the bed-plate so that when a wrapper is severed from the web,
it will fall upon the bed plate in position to be fed to the wrapping mechanism.
On the cross shaft 24, carrying the cam wheel 37, is fixed a cam 40 which is
adapted to rock a bell-crank lever 41 pivoted to the front side of the bed-plate 3.
One arm of the bell-crank lever carries a foller which bears against the cam 40,
the other arm being formed into a toothed segment 42 in engagement with a
pinion 43 fixed on a shaft 44, which extends across the bed-plate 3.
A gear
wheel 45 is also secured on the shaft 44, beneath the bed-plate (Figs. 2 and 3).
Lying against the underside of that part of the bed-plate over which the
web of wrapping material passes, and in line therewith, is a wrapper feeder 46.
This consists of a bar, suitably supported to move in a longitudinal direction,
and having teeth formed on one end to engage with and be moved by the gear
wheel 45. The opposite end, or that the nearer to the wrapping mechanism,
has a finger 47 secured thereon, the end of which is bent upwardly and forwardly
to form a hook 48 as represented in Fig. 3. The hook 48, which projects above
the bed-plate, rests normally beneath the cross bar 39, 50 that immediately
after the wrapper has been severed by the knife 32 the feeder 46 will be advanced
by the mechanism above. described, and its hook 48 engaging with the wrapper,
the latter is carried rapidly forward to the compression chamber B. Guide
plates 49 screwed to the bed-plate 3 prevent the wrapper from becoming dis-
placed during its forward movement. The wrapper feeder 46 is moved by the
rocking of the bell-crank lever 41, through the medium of the cam 40 on the
shaft 24, the toothed segment 42 on said bell-crank lever rotating the pinion 43
on the shaft 44, on which is the gear wheel 45, which engages the teeth of the
wrapper feeder 46.
A spring 50 connected to an arm 51 on the hub of the bell-
crank lever, and to the legs 2, keeps the bell-crank lever in contact with the
surface of the cam 40.
Secured to the bed-plate 3 are two brackets 52, 53 which support two side
plates 54, 55, their lower ends being slightly raised above the bed-plate to
permit the wrapper to pass thereunder, as indicated in Figs. 3, 5 and 6. These
plates 54, 55 are connected by a front plate 56 and a back plate 57 which plates
do not extend to the bed-plate but terminate some distance above it. These
four plates form a rectangular box which is divided into two chambers A, B
by an intermediate plate 58, parallel with the front and back plates, its lower
edge being in the plane of the lower edges of the said front and back plates.
The two chambers A, B, form, respectively, the tobacco receptacle and the
compression chamber. A door 59, adapted to slide horizontally in a frame 60

page_text: fixed in an upright position near the side plate 55, projects through a narrow
vertical slot 61 formed in the side plate 55 for the passage therethrough of the
door 59. A groove 62 is made in the bottom of the intermediate plate 58 to
guide the door, and form a tight joint between the two chambers A and B.
The sliding door 59 is operated by means of a cam wheel 59 fixed on the
shaft 12, and having a grooved cam in its side face, in which a roller mounted
apon an elbow lever 59b runs. The upper end of this elbow lever is connected
by a link to the sliding door 59; the rotation of the cam wheel rocking the
elbow lever, and causing the door 59 to slide in and out between the chambers A
and B at the proper time.
Projecting above and communicating with the chamber or tobacco receptacle A,
is a receiving hopper 64, into one side of which the hinged pan 65 of the weighing
scales 66 projects. The scales 66 rests on a shelf 7 supported by brackets
screwed to the side plates 54, 55.
Fixed on the shaft 12 is a cam 68, adapted to engage the foot piece 69 of a
vertical rod 70 and raise it against the force of a spring 71, which normally
tends to keep the rod in its lowest position. Pivoted to the vertical rod 70 is
a connecting rod 72 fulcrumed at its upper end to one of a pair of levers 73,
journaled to the side plates 54, 55. These levers are connected at their free
ends to bars 74 projecting in an upward direction, one on each side of the scale
pan, the bars engaging with pins 75 projecting laterally from the pan. As the
cam 68 rotates, the vertical rod 70 is raised, it through the connecting rod 72
lifting the levers 73; and, the bars 74 engaging the pins, the hopper 65 will
be raised, and empty its contents into the chamber or tobacco receptacle A.
Bolted to the front of the bed-plate near the left hand end of the machine,
and projecting forwardly, therefrom, are two guides 76 separated a suitable
distance, between which, in grooves formed in the inner sides thereof, slide two
plates 77, 78, each adapted to be moved independently of the other. To the
inner end of the upper plate 77 is fixed a plate 79 of width equal to that of the
chamber or tobacco receptacle A, and extending upwardly from the lower
plate 78, on which it bears, to the bottom of the front plate 56, its upper end
having a slight backward curve, as shown, (Figs. 4 and 5). When the plate 77
is in its retracted position, (Fig. 4), the plate 79 forms a front wall to the
tobacco receptacle A, while the rear wall is formed by the sliding door 59, and
the bottom by the sliding plate 78. It will thus be seen that a closed chamber
or box is formed, into which the tobacco is received from, the scale pan 65.
A rock shaft 80, journaled at the front of the machine below the plates 77, 78 in
a bracket S1 bolted to the bed-plate, and in two supporting frame plates 82, 83
below the bed-plate 3 and extending cross-wise thereof, has projecting from it
an arm 84 adapted to engage a grooved cam wheel 85 fixed to the shaft 12,
(Figs. 1, 2 and 4), by which means the shaft 80 is slightly rocked in its bearings.
Fixed to the rock shaft 80 between the supporting plates 82, 83 is an upright
arm 86, connected by a link 87 to a stud on the bottom of the sliding plate 78.
As the shaft 80 rocks, the plate 78 is moved a slight distance forward and back-
ward. Rocking on the same shaft, but disconnected therefrom, is a second
upright arm 88 connected by a link 89 to a stud 90 passing through a slot in
the plate 78, and bolted to the upper sliding plate 77. The arm 88 is pivoted
to a rod 91 which extends to the rear of the machine, where it is connected to a
lever 92 mounted on a rock shaft 93 supported in bearings on the legs 2. 2ª.
The lever 92 has a projecting arm 92ª carrying a roller 926 which bears on the
periphery of a wheel 94 having a cam surface 95 for operating the lever. A
second arm 92° extends from the rock shaft 93 in a direction opposite to that
in which the lever 92 projects. As the cam rotates, the cam surface 95, coming
in contact with the roller 92b, operates the lever 92 and slides the plate 77
rearwardly, pushing the tobacco contained in the receptacle A into the com-
pression chamber B. By this time, the highest portion of the cam surface 95
has reached the roller 92 when, after a short dwell, the plate 77 is retreated

page_text: slightly, to accomplish which the cam surface 95 is depressed at 95. As the
lever 92-is being moved by the cam surface 95, the arm 92c approaches the
periphery of the cam wheel until the roller carried thereby comes in contact with
it, which will be at the time that the roller 92b reaches the highest part of the
cam surface 95. When the cam wheel, in its-rotation,- brings the depressed
portion 95% of the cam surface 95 under the roller 92, the slightly elevated
portion 95 of the cam wheel acts on the roller of the arm 92, and rocks the
lever 92, which through the rod 91 and upright arm 88, causes the plate to be
slightly retracted, then rest, and finally return to normal position as the cam
surface 95 reaches and acts on the arm 92°.
Secured to the under side of the bed plate 3, below the compression chamber B,
is a frame 96, having two parallel sides 97, 98 which are substantially con-
tinuations of the rear plate 57 and the intermediate plate 58 of the compression
chamber B. To the frame 96 are fastened the two frame plates 82, 83, hereto-
fore mentioned. Between the sides 97, 98, and at a suitable distance below
the bed plate, is fixed a horizontal plate 99, which forms the bottom of the
compression chamber.
A hollow, rectangular box or former 100, (see Figures 3, 4, 5, 5 & 19) fitting
closely within the compression chamber B, is adapted to move vertically therein
by means of a forked lever 101, engaging with pins 100 projecting from the sides
of the said hollow former. The forked lever 101 is pivoted to a standard 102,
bolted to the top of the bed plate 3 (Fig. 4). Below the pivot of the lever 101,
is a rock shaft 102 parallel to the said pivot and journaled in bearings bolted
to the bed-plate. From the shaft 102 extend two arms 101, 101 parallel to the
lever 101, the former being immediately below the lever to which it is connected
by a link 101. The other arm 101 is pivotally connected to a vertical bar 105;
the lower end of which is attached to an arm 104 on the rock shaft 93, said arm
carrying a roller 104ª to enter a cam slot in the cam wheel 103, the required
movements of the hollow former or box 100 being caused by the shape of the
slot in the cam wheel 103. To the sides of the hollow former 100 are secured
vertical guides 106 which travel in grooves 107 formed in the side plates 54, 55
(Figs. 1, 3 and 4). In the front wall of the hollow former 100, is formed an
opening the full width of the former, and of a height equal to that of the
plate 19, (Figs. 4, 5 and 6), through which the tobacco is pushed from the
receptacle A into the chamber B by the plate 79.
Within the hollow former 100 is a compressing plunger 108 fitting closely
the hollow former, and having a movement independent thereof. The bottom 108*
of the compressing plunger is perforated for the escape of air as the plunger
descends, this being necessary because of the close fit maintained between the
plunger and the former. The compressing plunger 108 is operated from a
cam wheel 109, acting on a lever 110 connected by a link 111 to a second
lever 112, which latter is pivoted to the top of the standard 102 and to an adjust-
able connecting rod 113, connected to the compressing plunger 108. The adjust-
able connecting rod 113 consists of two parts, the bar 113 and the head 113
screwed thereon. By disconnecting the head from the lever 112, it can be
screwed up or down on the bar 113ª which will lengthen or shorten the con-
necting rod, whereby the thickness of the package is decreased or increased as
desired. The cam wheel 109 which operates the compressing plunger 108 is
shown in side elevation in Fig. 18. The cam groove therein has at one point a
movable wall 114, adapted to be set at varying distances from the center of the
cam to change the throw of the lever 110 and, through its connection, the
amount of compression given to the material to be packed..
The movable wall 114 forms one side of a block 114 pivoted at one end to the
cam wheel, and cut away at the other end for the insertion of an eccentric 115
pivoted to the body of the cam, and having means for fixing it in any desired
position. A spring plate 116 fixed to the movable block 114ª bears on the
eccentric and keeps it always in contact, with said block. Plates 117 are secured

page_text: in the cam groove on the side opposite the highest portion of the block 114",
which, by their number, regulate the depth to which the compressing plunger 108
can descend.
A modified form of compressing mechanism is shown in Figs. 24, 25 and 26.
As there represented, the compression chamber contains two plungers, an upper
one 108, and a lower one 99%, each plunger being operated through the medium
of a lever and a cam, the contour of the cams being such as to give the requisite
movements to the plungers.
Beneath the bed plate 3, and adapted to slide in bearings secured thereto,
are two package carriers 190, 191, (Figs. 1, 2, and 3), the former being on the
left and the latter on the right hand side of the compression chamber B. One
end of the carrier 190 projects beyond the left hand end of the bed-plate, to
which end is attached a link 192 connected to a vibrating lever 1933 pivoted to
an arm 194, secured to a standard 195. The shaft 12, which passes freely through
the hub of the arm 194, carries a cam wheel 196, in the groove of which a
roller 197, pivoted to the vibrating lever 193, travels. The rotation of the cam
wheel causes the carrier 190 to slide back and forth through the space where the
wrapper is applied to the material. The inner end 190 of the carrier stands
normally a distance away from the wing folders, substantially the same as the
thickness of a complete package. A wiper 198 is fastened to the carrier 190, the
purpose of which will be described hereinafter.
The carrier 191 rests normally at a relatively greater distance from the com-
pression chamber A than does the carrier 190. It is moved to and from the
compression chamber by a cam 199 fixed on the cross shaft 24 acting on સ
roller 200 on the end of an arm 201 of an elbow lever 202 pivoted on the shaft 41ª.
The other arm 203 of the elbow lever has a pin 204 projecting from it which
engages with a slot 205 in the end of an arm 206 on a cross shaft 207 journaled
in brackets 208 depending from the bed-plate. A second arm 209, fixed to the
shaft 207, and parallel with the arm 200, is connected to the carrier 191. by
means of link 210. A spring 211 is connected to the arm 209 and to the frame,
to keep the carrier in its retracted position and the roller 200 always in contact
with the cam 199.
A sufficient quantity of tobacco having been placed in the scale pan, it is
dumped at the proper time into the tobacco receptacle A, the door 59 being
closed and the plate 79 in its normal or retracted position, as seen in Fig. 4,
the former 100 and the plunger 108, however, being elevated to their highest
positions. The endless web having been fed to the knife and a suitable length
cut off to form a wrapper, it is advanced by the wrapper carrier so as to be
brought under the former. The former 100 now descends to its lowest position,
shown in Fig. 5, carrying with it the wrapper, which is thereby bent into a
U form as shown in Fig. 5. The door 59 now opens, and the tobacco is emptied
into the hollow former or box 100 through the opening formed in its front
wall. The compressing plunger 108 now descends, pressing the tobacco within
the hollow former between the perforated plate 108 of the plunger 108 and the
bottom 99 of the compression chamber B. As soon as the compressing
plunger 108 reaches its lowest point, the hollow former 100 rises, and the
carriers 190, 191 advance and press against the material to be wrapped. The
compressing plunger remains stationary until the hollow former has moved up
sufficiently to clear the tobacco, when the compressing plunger rises until its
bottom plate is above the edge of the U-shaped wrapper, when it stops, the hollow
former continuing its upwards movement until it reaches its full height before
stopping.
The parts are now in position for the wrapping operation, the mechanism for
producing which I will now describe, the first step being to finish the folding
of the wrapper around the material. Bolted to the front plate 97, of the
frame 96 are two brackets 118, (Figs. 2, 4 and 7), similar brackets 118 being
fastened to the rear plate 98. These brackets carry the first folders, which are

page_text: alike, and a description of one will therefore serve for both. A plate 119, adapted
to slide horizontally in grooves formed in the inside of the brackets 118, is pro-
vided on its end near the compression chamber with a hinge 120 to which are
pivoted folding fingers 121, which normally stand in upright position, (Fig. 4).
The under surface of the plate 119 is in the plane of the top of the compressed
-package, as clearly illustrated in Fig. 7. The axes of the folding fingers 121
are also in the same plane. A second plate 123, arranged to slide in grooves 122
in the brackets 118 just above the plate 119, has its end nearest the compression
chamber formed into hooks 124 which engage with loops 125 on the fingers.
The construction is such that, as the plate 123 moves back and forth, the
hooks 124 act on folding fingers 121 to either depress or raise them. Pivoted
in bearings on the plate 123 is a bell crank lever 120, one arm of which is adapted
to pass through an opening in the plate 123 and engage a slot 127 in the
plate 119, while to the other arm of the lever 126 is connected a spring 120
attached to the same plate, or an extension thereof. A stop 128 is secured to
the plate 119, and is so located as to strike a projection 129 of the bracket 118.
Depending from the plate 123, and passing through a slot in the plate 119, is a
stud 130 to which a link 131 is pivoted, its opposite end being pivoted to an
elbow lever 132 journaled on the frame plate 82. A downwardly extending
lever 134, pivoted to the side plate 82 as indicated in Fig. 4, carries a roller 135
which engages a cam groove in a wheel 186, by which it is operated. A rod 137
connects the lever 134 to one end of the elbow lever 182.
As thus constructed and arranged, the cam wheel 136 in its rotation acts on
the roller 135, and through the connections described moves the plate 123 from
the normal position, shown in Fig. 4, toward the compression chamber. The
stud 130 is connected to the plate 119, or to an arm projecting therefrom, by a
spring 1988; the tension of which and of the spring 126 is sufficient to cause the
plate 119 to move with the plate 123 until the stop 128 comes in contact with the
projection 129. The plate 119 is arrested while the folding fingers 121 stand
vertically within the openings 97ª of the plate 97.. The plate 123, however, with
the bell crank lever 126 continues to move forward, against the action of the
springs, which continued movement of the plate 123 will cause the hooked
ends 124 thereof to fold down to the position shown by dotted lines in Fig. 7.
carrying with it the upright sides of the U-shaped wrapper. The method of
folding the wrapper is an important feature of my invention. I have found by
experiment that, when the folding face of a folder is wholly in contact with the
wrapper from the point of fold, it is impossible to get a square sharp corner,
especially when folding over such a soft matrix as tobacco. By continued
experiment I have discovered that when the cover is so pivoted that its folding
face is radial to its axis and lies in the same plane as the surface of the material
to: be wrapped, and the extreme end only of the folder is permitted to come in
contact with the wrapper near its free end during the folding operation, the
folder will gradually bend the wrapper over the material as indicated in Fig. 7.
until it finally rests squarely on the upper surface of the tobacco, the result
being a sharp smooth corner. To obtain this result I construct the folders with
their folding surfaces radial to the axis of the folders, which, as heretofore
described, are in the same plane as the top of the material. When the folders
have completed their operation they will lie in a horizontal position with their
folding surfaces in line with the bottom of the plate 119. Having reached
this position, the bell crank lever 126. under the influence of the spring 126ª.
drops into the slot 127 in the plate 119 locking the two plates together. The
cam wheel 136 acting on the roller 135 of the lever 134 now moves the plate 123
away from the compression chamber, this action being facilitated by The
spring 138 carrying with it the plate 119 because of the connection of the bell
crank lever 126 therewith. As soon as the folding fingers 121 have been com-
pletely withdrawn from the compression chamber the bell crank lever 126 strikes
a stop 189, which causes the lower arm to be disconnected from the slot 127 in

page_text: the plate 119, which plate, under the influence of the springs 138 and 126,
moves in slides backwardly; and, by reason of the connection between the
hooks 124 and the loops 125, the fingers 121 swing upwardly to their normal
position. The folding mechanism on the opposite side of the machine, as
before stated, is similar to the one described, but it is actuated in a different
manner. A cam groove 140 in the cam wheel 103 operates an arm 141 pivoted
to the rock shaft 93, which is connected to the stud 130 by a rod 142. The cam
groove 140 is so timed that the folding mechanism operated thereby is brought
into action at a later period than the one herein before described, but is with-
drawn at the same time. The object of this unequal timing is to permit one
of the upright sides of the wrapper to be folded down over the opposite side.
As soon as the first folder fingers have withdrawn after folding the wrapper
over the material the plunger 108 quickly descends, pressing the folded sides
of the wrapper upon the tobacco and retaining them in position until the ends
of the package have been folded.
The first end folders, of which there are two, act on the upper projecting ends
of the wrapper.
Each folder cousists of a flat plate 143, having wings 143
extending from the side of a horizontal bar or finger 144 adapted to rotate
through an are of 90 degrees. The folding face of the folder 148 is radial to the
axis of the horizontal bar or finger 144 which is also on the plane of the end
of the material to be wrapped. The finger 144 projects from the end of a body
piece 145 which has a nut 146 screwed into its end through which a spiral
opening is made. Each body piece 145 is mounted on the spirally twisted end 147
of a rod 148, each of which extends rearwardly from the folders and is supported
beneath the bed-plate 3 (Figs. 4, 8, 9 and 10). Near the rear end of each rod 148,
is a connecting cross bar 149, to which one end of a link 150 is pivoted. The
other end of the link 150 is connected to an arm 151 secured to a rock shaft 152
journaled in bearings on legs 2 and 2ª, parallel to and above the rock shaft 93.
A curved arm 151, also fixed to the rock shaft 152, carries a roller on its free
end which bears on the periphery of the cam wheel 103, to which a cam block 154
is attached. As the cam wheel 103 rotates, the cam block 154 actuates the
curved arm 153, which, through the connections described, moves the rods 148
in a longitudinal direction. The spirally twisted ends 147 of the rods 148 pass
through the spiral openings in the nuts 146 of the body pieces of the folders 143.
Collars 155 are fixed to the rods 148, as shown. Springs 156 surround the
spirally twisted ends 147 between the nuts 146 and the collars 155. As the
rods 148 are advanced endwise, the folders, which lie in a horizontal position.
move with them owing to the tension of the springs 156, until the pointed end
of each finger 144 enters a conical depression 158 in the plate 97 of the frame 96,
(Figs. 8 and 9). The longitudinal movement of the folders will then be
arrested, but the rods will continue to advance, thus overcoming the force of the
springs 156, and rotate the folders downwardly and inwardly, carrying with them
the upper projecting end of the wrapper (Fig. 10). When the rods retract, these
folders will first return to their normal longitudinal position, after which they
will be withdrawn to permit the other folders to act.
The next step is to fold the side portions of the projecting wrapper. This is
done by four vertically pivoted wing folders or doors, two between each end of
the package. To the plate 97 of the frame 96, and near the ends of the bottom
plate 99 of the compression chamber, are pivoted two doors or wing: folders 159
adapted to move in an arc, longitudinally. A similar pair of wing folders are
pivoted to the plate 98 (Figs. 3 and 11). As in the previously described folders,
the folding faces of the wing folders are radial with their axes, which are in the
planes of the respective ends of the material to be wrapped. Horizontal plates
or tuckers 160 project from the folding faces of the wing folders for the purpose
of tucking the folds of the wrapper beneath the material. Sliding in grooves
on the upper edges of the frame plates 82, 83, and at each end are blocks 161,
each block being connected by a link 162 to one of the wing folders, as indicated

page_text: in Fig. 11. As the blocks slide back and forth, the wing folders are closed to fold
the projecting sides of the wrapper, and then opened again. Fixed to a rock
shaft 163 passing through the frame plates 82, 83, near their lower edges, are.
two vertical arms 164, 165 (Fig. 2). These arms, which are outside of the frame
plates, are each connected to a sliding block 161 by a link 166. Similar arms 167
in connection with links 168 operate the other two blocks. The rock shaft 169
on which the arms 167 are secured has fixed to it a sector plate 170 carrying a
roller 171 and a pivot for a connecting rod 172, the other end of which rod is con-
nected to the arm 164. A cam wheel 103, having a cam block 173 on its
periphery coacts with the roller 171 to rock the sector plate 170, which, through
its connections with the sliding blocks, causes them to operate the wing folders
as described.
The third and final end fold is made by a horizontal pivoted door or folder 174
at each end of the bottom plate 99. These third folders 174 lie normally in a
horizontal, or practically horizontal, position below the upper surface of the
plate 99, and come into operation after the wing folders 159 have retracted. The
third folders are operated by means now to be described. On the shaft 175
journaled in a bracket bearing 176 bolted to the left hand end of the bed-
plate 3, and in the frame plates 82, 83, is fixed an arm 177 carrying a roller
and a beveled pinion 178, which latter meshes with a bevel pinion 179 of similar
size, fixed on a shaft 180 journaled in the side plates 97, 98 of the frame 96.
On the shaft 180 is secured a spur pinion 181 and a curved arm 182. A second
shaft 183, parallel to the shaft 180 and in the same horizontal plane, has also
secured to it a spur pinion 184 engaging with the pinion 181, and a curved
arni 185, similar to the arm 182. The arm 182 is curved so as to pass under the
shaft 183, while the similar arm 185 curves under the shaft 180. The extremities
of these arms are pivotally connected to the third folders by rods 186. The
roller on the arm 177 enters a cam groove in the cam wheel 187 on the shaft 12
by which the arm is vibrated, causing the shaft 175 to rock in its bearings.
The rocking of the shaft 175 will, through the gearing above described, cause
the curved arms 182, 185 to operate the third folders, thereby completing the
wrapping operation. A reverse movement of the shaft 175 will, of course, open
the third folders and permit the package to be removed.
After the final end-fold has been given the package, it is ready for removal
from the compression chamber. This is accomplished by the carrier 190, 191
heretofore described as advancing as the hollow former 100 rises. Just before
the end folders begin to operate, the carriers retreat far enough to clear the
ends of the wrapper, and rest there until the third end folders have turned up
the final fold and retreated. The carriers then advance, grasp the ends of the
completed package, and carry it to the right until it has cleared the compression
chamber and pauses beneath the ejector plunger 212 above an opening 213",
formed in the frame 213. Secured to the bottom of the frame 213 at one side
is a fixed plate 214, projecting vertically downward from the edge of the
opening 213. Opposite the fixed plate 2.14 is a plate 215, standing in a vertical
position below the edge of the opening 213. The plate 215 is rigidly attached
near its upper edge to rods 216 supported in a horizontal position in brackets
beneath the support for the carrier 191. A spring 217 surrounds each rod
between the brackets, against one of which the spring bears while its other end
bears against a collar on the rod, as seen in Fig. 3. The tendency of the spring
s to push the rod and plate towards the fixed plate 214, but its movement in this
lirection is limited by a collar 218 on the rod. The normal distance between
he plates is slightly less than the length of a package, so that when a package
s pushed between the plates by the ejector plunger 212 it will be held there
y the force of the springs 217.
Connected to the plunger 212 by a suitably pivoted link 219 is an arm 220
ixed to a rock shaft 221, which turns in bearings on the under side of the bed-
late 3 (Figs. 3 and 13), and carries on its opposite end a downwardly extending

page_text: arm 222. Pivoted to a suitable support on the bed-plate near the arm 222, is
a second arm 223 also extending in a downward direction and connected to the
arm 222 by a link 224. Fixed on the shaft 15 is a cam wheel 225 which vibrates
the arm 223 through the means of a roller 226 entering the cam groove in the
cam wheel 225. The groove is so shaped as to depress the ejector plunger as
soon as the complete package has been brought beneath it, and force the package
between the plates 214, 215.
Beneath the lower edges of the plates 214, 215 is arranged a track 227 (Figs. 1, 2
and 3), extending crosswise of the machine and supported, as here shown, by
a standard 228 and an extension 229 from the leg 2. This track supports a
long box 230 (sec Figures 16 and 17) in which the completed packages are
arranged. The interior width of the box is somewhat greater than the length.
of a package, or the distance between plates 214, 215 which extend down within
the box. The height of the box may be varied as desired. It is here shown
equal to the thickness of five packages.
Fixed on the shaft 15 above the track 227 is an eccentric 231, around which
passes a strap in the usual manner, from which an arm 232 extends downwardly
and rearwardly (Figs. 1, 16 and 17). Near the shaft 15 and below the bottom
of the bed-plate 3, is a short shaft 233 supported in bearings 234, 235. Fixed
on this shaft is a ratchet wheel 236, the number of teeth thereon being deter-
mined by the number of packages it is desired to place vertically in the box 230.
Mounted loosely on the shaft 233 are two arms 237, one on each side of the
ratchet wheel, between which is pivoted a pawl 238 adapted to engage the teeth
of the wheel. The arm 232 is pivoted to one of the arms 237, so that as the
eccentric rotates the ratchet wheel will be revolved step by step. Suitably sup-
ported from the bed-plate of the machine, in position to enter the box 230, is
a push bar 239 lying parallel with the track, with its forward end, to which a
plate 240 is attached, standing normally just back of the plates 214, 215, while
its rear end bears against an elastic abutment 241. A spring 242, attached to
the push bar 239 and one of its supports, tends to keep it in this position. In
the upper edge of the push bar 239, a notch is made for the entrance of an arm 244
fixed on the shaft 233 and rotating with it. At each rotation of the arm 244,
the push bar 239 is carried forward.
As hereinbefore mentioned, the shaft 15 makes one rotation for each package
completed. The eccentric, therefore, must make five revolutions to one of the
shaft 233 and arm 244, there being five teeth in the ratchet wheel 236. The
ejector plunger 212 will, in the same space of time, have pushed five packages
between the two plates 214, 215. The push bar mechanism is so timed that
after the fifth package has been placed between the plates the push bar will be
moved forward by the arm 244, and force the five packages forward from between
the plates, which, bearing on the packages previously removed, push the box 230
forward sufficiently to receive another row of packages. To facilitate the
movement of the boxes 230, rollers 245 are journaled in the track 227.
alarm 246 is placed beneath the track to indicate to the operator when a box is
full and ready to be removed from the machine.
An
Figs. 21 and 22 illustrate the mechanism for applying the labels to the con-
tinuous web of wrapping material, and printing thereon (or on the continuous
web when the labels are not used) any desired words or devices; also means for
cementing webs of paper and metal foil, and feeding this compound web either
directly to the drawing rolls 30, 31 or to the labeling and printing mechanism.
Bolted on the top of the extreme right hand end of the bed-plate 3, are two
upright brackets 247, having fixed bearings at one end for the shaft 248 of a
roll 249, and adjustable bearings for the shaft of a similar roll 250. These
rolls, which are geared together, act as drawing rolls for feeding the compound
wrapper through the labeling mechanism. Fixed on the shaft 248 of the
roll 249 is a sprocket wheel 251, over which passes a chain 252 extending upwardly
from a sprocket pinion 253 on the end of the cross shaft 25 which, as herein-

page_text: before described, is driven from the shaft 15 through the medium of beveled
pinions 21, 23. The pinion 21 is adjustably secured to the shaft 15 by a set
screw as shown, so that it can be moved back out of engagement with the beveled
pinion 23. The drawing rolls 249, 250 are of the same diameter as the drawing
rolls 30, 31, and on each half revolution feed sufficient material to form a wrapper.
The sprocket wheels 253, 251, therefore, are proportioned as two to one.
A
receptacle 254, open at its top and front end, is pivoted at its upper right hand
corner 255 to the brackets 247 in advance of the drawing rolls 249, 251; while
from the front and back of the receptacle, near the bottom, project pins 256.
A shaft 257, rocking in bearings on the brackets. 247 beneath the receptacle 254,
carries two arms 258, which extend upwardly, one at each end of the receptacle
against which the pins 256 rest. Secured to the front end of the rock shaft 257
is a downwardly extending arm 259 carrying a roller which bears against the
periphery of a cam wheel 260 on the cross shaft 25. Each rotation of
the cam wheel operates the arm 259, and swings the receptacle 254
on its pivot 255. towards the drawing rolls 249, 250, the receptacle returning by
its own weight as soon as the elevated portion of the cam wheel has passed the
roller on the arm 259. Within the receptacle 254, is placed a box 261 which
can be slid therein through the open front. The box 261 is of such shape and
size as to carry the labels 262 flatwise without permitting lateral movement.
The labels rest on a follower 263 which is forced upward by a spring 264 as
shown, the labels being held within the box by upwardly projecting flanges 265
on the top of the box. A roller 266 is journaled in the brackets 247 above the
label box at the side nearest the drawing rolls 249, 250.
A pasting device 267, which is screwed to the flanges 268 extending inwardly
from each bracket 247, consists of a curved trough 269, with end pieces 270
through which pivot points 271 pass. Pasting disks 272 on the shaft 273 are
adapted to revolve on the pivot points 271, one of which is adjustable. The disks
are of the same diameter as the drawing rolls 30, 31, and are cut away as shown
at 274. A guide roller 275 is mounted in arms projecting from the end
pieces 270 of the pasting device. Similar rollers 276, 277 are journaled in the
brackets 247, the former being on the opposite side of the pasting device, and
the latter near the shaft 257 at the bottom of the brackets. A bracket 278
carrying a pasting device 267 (shown in dotted lines) will be attached to the
end of the bed-plate 3 for certain purposes, while a similar pasting device 267",
under certain circumstances, is fastened to the bed-plate below the drawing-.
rolls 249, 250.
A printing press 279 of any suitable and approved form can be secured to.
the bed-plate between the drawing rolls 31, 32 and 249, 250. Bearings 280,
bolted to the legs 2b, afford support to a roll 281 of metal foil when such is to be
used. Extensions 282 of the brackets 247 have bearings 283 in which a roll of
waxed paper or other material can be placed.
While I do not consider it necessary to apply paste to the overlapping edge
of the wrapper, provision is made for its use." For the purpose of applying
paste or cement to the wrapper, I attach to the bed-plate, in any convenient
position that will permit the cement being applied to the web before it reaches
the drawing rolls 30, 31, a pasting or cementing device such as is shown in
Figs. 14, 15. It consists of a can or receptacle 284 supported on the upper end
of a rod 285, which is made adjustable in height and has spring fingers for
holding the can. From near the bottom of the can a downwardly curved tube 286.
having a stop cock 287; projects, to which I fasten a section of flexible tube 288.
The other end of the flexible tube 288 is secured to a small rigid tube 289 having
an outlet 290. The tube 289 passes through an outer tube 291, threaded at one
end and having two projecting. fingers 292 at the other end in which a paste.
applying wheel 29: rotates, its periphery being in close proximity to the out-
let 290. A threaded sleeve 294, capable of being rotated on the small tube 289,
is screwed on the threaded end of the outer tube 291. The arrangement is such

page_text: that, as the sleeve 204 is rotated on the outer tube 291, the paste applying.
wheel 293 is drawn nearer to or moved from the outlet 290, thus permitting
more or less cement to descend through the tube 289, to be taken up by the
wheel, and applied to the edge of the continuous web of wrapping material.
The several parts of my invention having been described in detail, I now pro-
ceed with a description of the general operation, as employed in packing and
wrapping tobacco.
The operator stands at the front of the machine near the scale pan 65 a recep-
tacle containing about two hundred pounds of tobacco, more or less, being
within convenient reach. The operator by means of the handle 7 throws the
clutch 6 into engagement with the driving wheel 5 and starts the machine
running. A weight equal to the weight of tobacco to be contained in each
package having been put upon the scale, tobacco is placed in the pivoted scale
pan 65, until it balances the weight. The pan is then ready to be dumped. At
this moment the cam 68 will be on the point of raising the rod 70 to dump the
scale pan; the sliding plate or door 69 between the tobacco receptacle A and the
compression chamber B will be closed; the knife 32 will be raised high enough
for the web 28 to pass under it; the hollow box or former 100 will be at its
highest elevation and the packing plunger 108 will be lowered to the folding
position. The folding fingers 121 will be in their retracted position, the first
end folders 143 will be retracting while the wing folders 159 will be on the point
of closing, and the third or last folders will be turned almost ready to act. The
upper and lower sliding plates 77, 78 will be in their retracted position as will
also be the carriers 190, 191, and the wrapper feeder 46.
The compound
wrapper 28, wound in a roll 27, passes over the idle roller 29, and along the top
of the bed-plate but not touching it, to the drawing rolls 30, 31 which unrolls it
steadily and feeds it over the bar 39 and under the knife 32. When the edge of
the wrapper is to be cemented, the cement is conveniently applied at the point
shown in Fig. 3.
•
The continued running of the machine rotates the cam 68, causing it to raise
the rod 70 and, through the various connections, tilt the hopper 65 emptying its
contents into the tobacco receptacle A, when they fall on the lower sliding
plate 78, between the vertical door 69 and the vertical plate 79 on the inner end
of the upper sliding plate 77.
The drawing rolls 30, 31 have by this time fed past the knife 32 sufficient
wrapping material to form a wrapper, which is cut from the web by the descent
of the knife, under the influence of the spring 38, after it has been raised to its
highest point by the cam 37 acting on the elbow lever 35. After cutting off
the wrapper which falls on the bed-plate 3, the knife is raised immediately so
that the web may pass thereunder. The compressing former 108, which up to
this time has been lowered to the folding position, is now raised slightly, stops
for a moment, and is then carried up to its full height. By the time the
plunger 108 reaches its highest position, the wrapper feeder 46 begins its forward
movement. Its hooked end 48 engages with the wrapper and carries it under the
former as shown by dotted lines in Figs. 1 and 4, over the opening 96* in the
frame 96, and then returns to its normal position. After the wrapper has reached
the position indicated, and during the return of the wrapper feeder, the hollow
box or former descends, and, passing through the opening 96 in the frame 96,
carries the wrapper with it until it rests on the bottom plate 99 of the com-
pression chamber B, bending the wrapper into a Ụ form. See Fig. 5ª. When
the hollow former 100 reaches its lowest position, the opening 100 in the front
wall of the hollow former 100, is opposite the sliding door 59 between the
chambers A, B. This door is now opened and the lower sliding plate 78 moved
sufficiently to cover the space 96ª between the frame 96 and the side of the
former 100 (Fig. 5). The upper sliding plate 77 then moves toward the
chamber B, and the vertical plate 79, attached to the sliding plate, pushes the
tobacco which is resting thereon towards and into the hollow box or former 100,

page_text: the tobacco falling upon the horizontal portion of the U-shaped wrapper. The
vertical plate 79, which extends below the upper plate 77, just touches the lower
plate 78 and sweeps therefrom all particles of tobacco which adhere, and which
are especially found to do so when the tobacco has been treated with much
saccharine matter. The vertical plate 79, it will be seen, acts as a cleaner for
the lower plate. After the tobacco has been emptied into the hollow former 100,
the slide 78 is retracted. The upper slide 77 is withdrawn a short distance or
until the inner faces of the vertical plate 79 and the front wall of the hollow
former 100 are in line. The compressing plunger now descends to press the
tobacco into shape within the hollow former. In its travel, the bottom plate 108"
of the compressing plunger, scrapes away any tobacco which may adhere to the
vertical plate 79. The upper sliding plate 77 then returns to its normal position.
The compressing plunger 108 as before stated, is operated by the cam wheel 109.
the adjustment of the cam wheel being such that that part of the groove, formed by
the movable wall 114, will act on the roller of the arm 110 to draw down the
compressing plunger 108 and press the tobacco into shape. The object of this
movable wall is to increase or decrease the amount of pressure on the tobacco,
some varieties requiring more pressure to reduce them to a certain bulk. than
others. After the compressing plunger has fully pressed the tobacco, it dwells
briefly in this position while the hollow former or box 100 rises to its full
height. As soon as it has passed the compressed tobacco, the package carriers 190),
191, which have been moving toward the compression chamber B continue to
advance and bear against the ends of the compressed tobacco left unsupported
when the hollow former was raised. The compressing plunger is also elevated
as soon as the hollow former clears the tobacco, until its bottom plate 108³ is
above the ends of the U-shaped wrapper, when it stops.
:
The first fold now takes place, by the advance of the plates 119, 123, which
carry the folding fingers 121 that turn down the vertical sides of the U-shaped
wrapper, as herein before described. The fold is made first on the uncemented.
side (supposing cement to be used) so that the cemented side will be above and.
when folded down, adhere to the uncemented side. On completing the fold, the
fingers are drawn back and the compressing plunger quickly descends onto the
partially folded package and hold the folded portions of the wrapper in place.
The second descent of the plunger is usually less than the first, its limit being
determined by the thickness of the completed package, which is the distance
between the bottom plate 99 of the compression, chamber and the plane of the
axes of the folding fingers 121. The adjustment to the required distance is
effected by means of the adjustable connecting rod 113, herein before described.
By the time the compressing plunger 108 has descended the second time, the
sliding door 59 has advanced and closed the opening between the two
chambers A, B, thus making ready the tobacco receptacle for another measured
charge of tobacco.
The carriers 190, 191 which up to this time have been supporting the ends of
the pressed tobacco, recede sufficiently far to clear the end folders, which now
begin to operate. The first end folders 143 are moved into position in line with
and above the ends of the wrapper, projecting outwardly in a horizontal position.
They are then turned downwardly into a vertical position, folding the projecting
wrapper against the tobacco and giving it a sharp square bend at the corner,
after which they turn up to the horizontal position and pause. The second end
or wing folders 159 are now brought into play and fold the sides of the extended
parts of the wrapper against the package, the projecting plates 160 tucking the
fold of the wrapper under the tobacco. During this operation the first folders 143
retreat, and a second measured quantity of tobacco is delivered into the tobacco
receptacle to await the opening of the sliding door, and the advance of the plate 79.
by which it is pushed into the compression chamber. The wing folders are then
returned to their normal positions.
The final fold is given by the third end folders 174, which turn upwardly and.

page_text: fold the remaining portions of the projecting wrapper against the package, thus
completing the folding operation. The final end folders after making the last
fold immediately return to the horizontal position, to permit the carriers 100.
191 to move towards the package against which they press, and carry it from the
compression chamber to a position beneath the ejector plunger 212. At the
time the carriers are advancing, the compressing plunger is given a slight upward
movement, the object of which is to permit the easy removal of the package.
and also to give the bottom plate 108 of the plunger a chance to be cleaned of
any loose tobacco (by the wiper 198 on the carrier 190) as the package is being
removed from the compression chamber.
The ejector plunger 212 is now ready to move downward. Before it does so,
the knife has severed a wrapper for the next package, and the compressing
plunger has been raised to its highest position. The downward movement of
the ejector pushes before it the finished package which is secured between the
two plates 214, 215, and there held until a sufficient number have been collected,
when they are moved therefrom by the push har 239.
In the modified form of my invention (see Fig. 25), after the wrapper has been
fed into position across the compression chamber B, the lower plunger 99* rises
and assumes a position in which its upper surface is in the plane of the bed-
plate 3 and immediately beneath the wrapper. The upper plunger now descends
upon the wrapper, which is gripped between the upper and lower plunger. Both
plungers now descend together, carrying the wrapper downward and forming
it into a flattened U-shape. The upper plunger then rises to a position above
the opening between the chambers A and B.
The side plates 5, 6f also descend upon the wrapper with the upper plunger;
and by the pressure of their thin lower edge crease or score the wrapper pre-
paratory to the last end fold. When the plunger rises, these plates remain
down, acting as temporary end closing devices to the U-shape of the wrappers,
and forming therewith a completely walled chamber.
After the requisite charge of material has been placed in the U-shaped wrapper,
the upper plunger descends on the material, compressing it to the requisite
thickness and solidity, the lower plunger in the meantime remaining stationary.
Both plungers now descend until the material is in position to be acted on by
the folders, the aperature in the table 3 being large enough for this purpose,
when the upper plunger and the side plates 5, 6 ascend. The folders now
operate on the wrapper and enclose the material therein.
The package is now complete, with the exception of the last fold, which is
accomplished by the downward motion simultaneously of both upper and lower
plungers, thereby carrying the package further down the rectangular chamber,
thus bending upward the last fold by contact with the edge of the chamber.
The plunger 190* now moves forward, thereby discharging the completed package
into the passage 190 when another package is formed behind the one already
completed, and a second forward motion of the plunger 190* forces both packages
forward, the first package to the end of the passage 190 directly beneath the
plunger 212, which now descends upon the first completed package, forcing it
downward between the plates 214, 215.
Besides feeding the compound wrapper directly to the drawing rolls 30, 31
from the roll 27 over the idle roller 29, as herein before described and shown,
I can secure, by means now to be described, a label to the foil, or that surface of
the wrapper which is exposed when the package is complete. To do this, I pass
the compound wrapper 28 from the roll 27 over the idle roller 276 (Figs. 21 & 22)
on the brackets 247, thence over the pasting disks 267 which apply paste in
longitudinal lines, broken where the web bridges the cut away portions 274 of
the disks. These unpasted portions correspond to the ends of the wrapper which
are to be folded, and therefore require no label. The moving parts are so timed
that the lines of paste on the wrapper, which correspond in length to that, or
to the length or width, as the case may be, of the label, are immediately over the

page_text: eceptacle 254, just as the cam wheel 260 causes the fingers 258 to swing the
receptacle on its pivot, carrying one edge of the top label against the lines of
paste. The label adheres to the continuous. wrapper, and is drawn by it out
of the receptacle which immediately returns to its normal position. The label
is pressed firmly in contact with the wrapping material as it passes through
the drawing rolls 250, 251. If printed matter is to be placed on the label the
web passes through the printing press 279 on its way to the drawing rolls 30, 31.
When a sheet of waxed or paraffined paper is to be used in connection with the
compound wrapper, a roll 283 of such paper is mounted on the extension 282
of the brackets 247, and the web passed under the idler 266.
When the separate webs of wrapping material such as foil and paper, are
used, the roll of papers takes the place of the compound wrapper roll 27, and
the roll 281 of foil is supported by the brackets 280. The web of foil passes
from the roll 281 over the idle roller 29, and under the idler 29ª to the drawing
rolls 30, 31, while the paper passes in the same direction, if it is not to be united
to the foil; but if otherwise the paper will pass over the pasting device 267.
and under the idler 29ª, at which point it joins the foil. Separate webs of
paper and foil may also be used with the labeling device by passing the web of
foil over the roller 277, and under and around the roller 276 to the pasting
device 267. the paper, in the meantime, passing over the pasting device 267
and around the roller 277, where it joins the foil. If the paper is not to be
united to the foil, it passes directly to the roller 276.
