Improvements relating to the Wrapping of Newspapers and other
Publications.
I, HENRY EDWARD NEWTON of The Office for Patents, 6 Bream's Buildings,
Chancery Lane in the County of London, Patent Agent, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:―
The object of the present invention is to provide an improved method of wrapping
newspapers and other publications, and an improved machine of that class used for
this purpose, and known as newspaper-wrapping machines, and especially to
increase the speed at which such publications may be wrapped, and to provide a
simple and efficient machine of high capacity.
By the method forming part of the present invention, the paper and wrapper are
rolled together to form a cylinder, and the paper and wrapper then led off by their
leading ends, with the rear end of the wrapper overlapping the first layer of
wrapper upon the paper, so as to be pasted down and secured by suitable pressing
devices; and in carrying out the invention the paper and wrapper are preferably
wound upon a core which supports the paper only through a portion of its width,
and the wrapper applied to that part of the paper not directly supported by the
core, so that the curve on which the paper is rolled is determined by the core,
while at the same time the leading ends of the paper and wrapper may be led off
the core to the pressing devices, with the rear end of the wrapper overlapping the
first layer of wrapper upon the paper, the portion of the wrapper not supported by
the paper being carried in against the paper as the latter changes from cylindrical
to flat form.
It is evident that this method, employing a core, may be carried out by machines
of widely different constructions, it being necessary, for a hand-fed machine, only
to provide a core, and suitable means for winding the paper and wrapper thereon,
and feeding and pressing devices by which the paper and wrapper are delivered
from the core, and the wrapper.pasted down, and the addition of pasting mechanism
and feeding devices for advancing the papers and wrappers to the core in proper
time, producing a machine entirely automatic in its operation and of high capacity.
In carrying out the invention, however, there is preferably employed a rotating
core, by which the paper is supported through only a portion of its width, this core
being formed preferably of two cylinders supporting the paper at its opposite side
edges, and the wrapper applied to the portion of the paper between the cylinders,
the wrapper being of less width than this portion of the paper. The length of the
paper is preferably substantially one half of the periphery of the core, and the
wrapper of sufficient length to extend completely about the paper on the core, and
overlap upon the first layer of wrapper sufficiently for pasting. The leading ends
of the paper and wrapper are taken by the core simultaneously, and the paper and
wrapper are wrapped upon the core during one rotation of the latter, and upon the
second rotation are led from the core by suitable feeding devices, the part of the
wrapper not supported by the paper being carried in so as to lie against the paper,
and the rear end of the wrapper overlapping the first layer of wrapper upon
paper is pressed down by suitable pressing devices, so as to be pasted by paste
previously applied either to the rear end of the wrapper, or to the first layer of
wrapper upon the paper, the wrapped paper thus being delivered as
product.
the

A

page_text: It is evident that the construction thus briefly outlined, may be varied widely;
that any suitable means may be used for securing the winding of the paper and
wrapper upon the core during the rotation of the latter; and that the leading ends
of the paper and wrapper may be advanced by positive engagement by the core,
or by friction between the core and feeding devices co-operating therewith. The
.ineans for delivering the paper from the core, and pressing the paper for pasting to
form a flat product, also may be of any suitable form. It is preferable, however,
to use for advancing the paper and wrapper, feeding devices co-operating with the core,
so that the paper and wrapper are advanced without being positively gripped, and there
are preferably employed, as the feeding devices, belts moving in the same direction,
and at the same speed as the core, so as to co-act therewith in advancing the paper
and wrapper.
In delivering the paper and wrapper from the core, a switch is
preferably employed, which allows the paper and wrapper to pass with the core
in its first rotation, and is shifted on the second rotation into position to guide the
paper and wrapper from the core, and into the grasp of delivering tapes or similar
feeding devices, by which the pasted wrapper is secured by pressure, and the
wrapped paper delivered as a flat product. With this construction there is
combined a pasting mechanism which may apply paste to the layer of wrapper
upon the paper during the first rotation of the core, or to the flap of the wrapper.
As it is evident that the paper is not folded during the wrapping operation of
this machine, it must be folded down to the required length before delivery to the
wrapping devices, and this folding of course may be accomplished in the same
machine, or the papers may be folded previously, and the wrapping mechanism
form an independent machine, which may be feit by hand or suitable feeding
devices. Thus, the wrapping mechanism may be combined with the delivery
mechanism of a printing press, or with a folding machine of any of the common
forms, wrapper feeding and pasting mechanisms being added, so that the folded
paper is automatically wrapped and delivered; or wrapper and paper feeding
devices of any suitable form may be combined with the wrapping mechanism, to
form an independent paper or pamphlet wrapping machine.
In the accompanying drawings, forming a part of this Specification, there are
shewn machines embodying the invention in the preferred forms, and a full
description of the same will now be given in connection with the drawings, and the

As
Referring now especially to the machine shewn in Figures 1 to 6, the frame of
the machine may be of any suitable form to support the operating parts.
shewn, it consists of the two end frames A, B, in which all the parts of the
machine are supported. The core upon which the paper and wrapper are wound,
consists of two short cylinders C, D, carried by shafts 11, 12, mounted in the
opposite end frames A, B, and in the upper part of the machine, the cylinders
extending within the frames, so as to engage and support the paper at its opposite
side edges. With the cylinders C, D, co-act belts E E, extending partially about
the cylinders from the side on which the paper is received, these belts being driven
from a roll G mounted in the frames A, B, above the cylinders. These belts are
guided about the upper part of the cylinders, under a roll H, mounted in the
frame, and are returned about a roll I, and over the roll H, the roll I forming one
of the delivery rolls I, K, of the machine, the belts E E thus acting as feeding
belts in combination with the cylinders, to wind the paper about the core, and
forming also one set of the delivery belts, by which the wrapped paper is delivered,
the other set consisting of a series of short belts L extending about the second
delivery roll K, and driven from a belt-driving roll M. The belts E E may be
found to extend inside the cylinders C, D, and engage the wrapper, so as to feed it
forward with the paper; but in the construction shewn, a series of independent
belts N are used for this purpose, these belts being led over rolls G, H, I, and driven
by roll G in exactly the same manner as belts E E, so as to form part of the
delivery belts between the rolls H, I.
The roll G coacts with a roll O mounted in the frames A, B, below it, to form a
pair of feeding rolls by which the leading ends of the paper and wrapper are
received and advanced over guides P and P to the core. These guides P and P
are curved parallel with the circumference of the cylinders C, D, and the line of
movement of the paper and wrapper, and lie between the cylinders, extending about
the core nearly to the roll H, and are constructed, as shewn, so as to extend
backward from the point at which the paper and wrapper are received, to form
guides P by which the paper upon the core is guided during a portion of its
rotation, when the leading end is not engaged by any of the feeding belts, although
it will be understood that separate guides may be provided for this purpose if
desired.
The guides Pare preferably made of spring metal, so as to yield slightly as the
paper is led above and below them, and thus accommodate papers of different
thicknesses, and the belts N co-operate with the guides P to advance the rear end of
the wrapper during the delivery of the paper.
Feeding belts, R, are provided below the cylinders C, D, corresponding in
position and action to the belts E E, above the cylinders. These belts are driven
from roll S, and led about roll T. A series of guides U, corresponding to the
guides P, are provided opposite the belts Q, R, between the cylinders C, D, these
guides acting to guide the leading ends of the paper and wrapper, and extending
in the line of movement of the core to the rear end of the guides P', so that the
paper and wrapper are positively guided thereby, and the wrapper held pressed
against the surface of the paper during the rotation of the core.
Between the rolls H, S, is mounted a switch T, carried by rock shaft 21,-
adapted to be rocked so as to throw the switch from the position shewn in Figure 4,
in which the paper and wrapper are guided about the core from the roll H to the
belts Q, R, during the first wrapping rotation of the core, to the position shewn in
Figure 6, in which the leading ends of the paper & wrapper are guided off to the
delivery belts during the second delivery rotation of the core.
The switch V consists preferably of a series of fingers extending in opposite

page_text: directions, and forming guides for the paper and wrapper, the rolls H, S, being
grooved to accommodate the fingers, so that the full space between the rolls H, S,
is filled by the switch. A plate extending over the full space occupied by
the fingers shown, may be substituted, however, if desired, the rolls H, S, being
so positioned that the switch may move through a sufficient are for guiding the
paper from the core.
For pasting, there is provided a paste fountain W, and fountain roll X, by which
paste is applied to a rotating paster Y mounted in position, and arranged to apply
paste to the desired portion of the paper. As shewn, the paste is applied to the
rear end of the paper, the wrapper being of a length three times that of the paper,
although it will be understood that the wrapper may be shorter, and the paste
applied to any other desired portion of the paper. The paster Y is constructed to
apply paste to the portions of the paper between the guides U, and the guides l'
are cut away to correspond with the guides U, so that the pasted portions of the
paper will pass forward out of engagement therewith, but will be brought into
contact with the wrapper as the leading ends of the paper and wrapper pass beneath
the guides P on the second rotation.
The operating parts of the machine are driven from the main driving shaft Z by
the following connections.
The shafts 11, 12 of the cylinders C, D, are provided with gears 13, 14, which
are engaged respectively by gears 15, 16, carried by the shaft of roll G. The
roll G carries also, at one end, inside the gear 16, a second gear 17, which engages
a large driving gear 18 carried by the main driving shaft Z. As will be seen, the
gears are so timed that the cylinders C, D, are rotated twice to each rotation of the
main driving shaft Z, and the belts E, E, N, driven by roll G, move at the same
rate of speed as the cylinders. The belts L, Q, R, are driven from the rolls M, S,
which are geared together by gears 19, and driven from core D by gear 19 on roll S
meshing directly with gear 40 on shaft 12. The feeding roll O is driven directly
from the roll G by a gear 20 engaging with gear 17. A uniform speed is thus
secured for all the parts co-acting with the core in advancing and delivering the
paper.
The switch V is carried by a rock shaft 21 mounted in the side frames A, B, and
provided, outside the frame A, with a crank arm 22, connected by a pitman 23,
with a bell crank lever 24, pivotted on the frame, the other arm of which carries a
bowl which rides upon a cam 25 carried by the maining driving shaft Z. The
shaft 21 is normally rocked into position to hold the switch in the position shewn in
the main views, and Figures 4 and 5, by a coiled spring 26 on the pitman 23, held
between the adjustable collar 27 on the pitman, and a lug 28 on the frame A,
through which the pitman slides. The cam 25 is so constructed as to hold the
switch in the position shewn in Figures 4 and 5 during the first rotation of the
core and a portion of the second, and then to throw the switch into the position
shewn in Figure 6, so as to guide the leading end of the paper and wrapper between
the rolls H, M and the delivery belts, the switch at the same time operating to
throw in the unsupported part of the wrapper against the body of the paper, the
paper and wrapper being pressed the switch fingers and the roll H, and fed by
friction between the two, until they reach the roll M, and are grasped by it and the
belts, E, E, N.
The pasting mechanism is operated as follows:—
The shaft of the paste fountain roll X carries gear 29, which meshes with a gear
30 on the shaft of the paster Y. The shaft of the fountain roll carries also a larger
gear 31 which ineshes with a gear 32, carried by a stud mounted in frame B, and
which carries also a large gear 33, which meshes with a gear 34 on the main driving
shaft Z, these gears being so timed, as shown, that the paster rotates in unison with
the main driving shaft, and, therefore, rotates once to each two rotations of the
cylinders C, D, forming the core, the paste thus being applied during the first
rotation of the core with the paper and wrapper thereon.
The operation of this machine will be understood from a brief general description

page_text: in connection with the drawings and the detailed description of the parts above
given.
As shown in the main views and Figure 4, the paper and wrapper y have been
received by the belt roll G and feeding roll O, and advanced thereby over the
guides P to the cylinders C, D, forming the core, and the belts E, E, co-operating
therewith, the paper being of such a width as to overlap upon the cylinders, and the
wrapper of less width, so as to lie entirely between the cylinders, and be advanced
by friction between the belts N and the paper, as shown in Figure 3. On the first
rotation of the cylinders, the switch V is held in position, as shown in Figure 4, and
the paper and wrapper are wound upon the core, passing inside the switch, and
being held upon the core during this rotation by the belts R and guides U, P', paste
being applied by paster Y to the layer of wrapper upon the paper in proper position
for pasting, all as shown in Figure 5, in which the core is shown as just commencing
the second rotation. Upon the second rotation of the core, the leading ends of the
paper and wrapper are carried under the guides P, and, as shown in Figure 5; the
rear end of the wrapper overlaps upon the layer of wrapper on the paper, so that
the two layers of wrapper are in contact between the guides T, to which space the
paste has been applied to the layer of wrapper upon the paper by the paster Y.
the second rotation of the core continues, and the leading end of the paper
approaches the switch V, the switch is actuated by the cam 25 and connections
previously described, and thrown into the position shown in Figure 6, so that it
operates to guide the leading end of the paper and wrapper from the cylinders to
the delivery belts E, E, N, L, the switch V co-acting with the roll H and
belts E, N, to advance the paper until it is gripped by the roll M and delivery belts.
As the leading ends of the paper and wrapper are thus led from the core, the loose
portion of the wrapper is carried inward onto the inner surface of the paper, as
shown in dotted lines in Figure 6, and as the paper and wrapper are advanced
between the delivery belts, the rear end of the wrapper is pasted down upon the
layer of wrapper on the paper, and the paper delivered in flat form between the
rolls 1, K, the pasted portion of the wrapper being pressed a sufficient length of
time by the delivery belts and rolls, so that the wrapper is firmly secured upon the
paper.
As
In the construction shown, the length of the paper is substantially one half the
periphery of the core, so that the portion of the wrapper about the core not
supported by the paper, is substantially the length of the paper, and is simply
carried inward against the paper in delivering. While this construction is preferred,
however, it will be understood, that a longer paper may be wrapped, provided the
grip of the delivery devices is loose enough to allow the wrapper to slip therein as
the paper is straightened out, so as to draw up the rear end of the wrapper, to afford
sufficient wrapper to extend about the flattened paper.
While there is shown as the preferred construction a machine in which the paper
and wrapper are gripped by belts coacting with the cylinders to advance the paper
and wrapper, it is evident that other feeding devices may be used in place of the
belts. Thus, there is shown in Figure 7 a construction substantially the same as
that previously described, except that the belt roll G and belts carried thereby are
omitted, and the paper and wrapper are advanced to the wrapping mechanism by
two feeding rolls O and in place of the belts E, E, N, coacting with the
cylinders C, D, to advance the paper and wrapper, feeding rolls 41, 42, are used,
and a second set of guides 43 outside the guides P', these feeding rolls 41, 42 being
grooved and cut away opposite the guides 43, as shown, so as to project inside the
guides, and grip the paper and wrapper in the same manner as the belts E, E, N.
In place of the belt rolls S, T and belts Q, R, short rolls 44, 45 are used, coacting
with the cylinders C, D forming the core, the wrapper being held and guided by
the guides U, as the paper is advanced by the cylinders and rolls. The operation
of this construction is identical with that previously described, the feeding rolls
simply being substituted for the belts as feeding devices, and no further description
is necessary.
i

page_text: While it is preferable to employ feeding devices which co-act with the
cylinders C, D, to advance the paper by friction, it is evident that a construction
may be used in which the paper and wrapper are positively gripped by the core,
and carried with it during the first rotation, and released on the second rotation, to
allow them to be guided from the core for delivery. Such a construction
is shown in Figures 8, 9, and 10, in which each of the short cylinders C, D,
forming the end cores, is provided with a gripper a, operating to seize the
leading end of the paper and wrapper. These grippers a may be of any
suitable form, and arranged in any suitable manner, to allow the paper and
wrapper to be led from the core, but the construction shown is preferred, in which
the grippers are cut away on their inner sides, so as to form an inclined surface,
and are so mounted as to grip the paper against the cylinder over a considerable
surface, but to hold the wrapper against the paper only by a small surface at the
inner point of the grippers. With this construction, the wrapper will readily slide
off the gripper without tearing, as the paper is removed in the manner shown in
Figure 6, and the loose part of the wrapper carried inward against the body of the
"paper.
The grippers a may be mounted and actuated in any suitable manner to secure
their proper movement for gripping the paper and wrapper during the first rotation
of the cylinder, and releasing them during the second rotation for the delivery of
the wrapped paper. There is shown a common construction of gripper mounting,
in which the grippers a are carried by short shafts 46, mounted in the
cylinders C, D, and provided with crank arms 1, 2, extending in opposite
directions, the former of which is spring-pressed by the common spring-pressed
rod 3 to close the gripper, and the other of which carries a bowl 4 running on a cam
for operating the gripper.
It is evident that the cam must be so formed that the gripper shall remain closed
during the first rotation of the core, be opened on the second rotation for the
delivery of the paper, and be again in position to seize a paper and wrapper at the
-beginning of the next rotation.
This result is obtained by the following construction.
The shaft 21 carrying the switch V carries also a cam 47, mounted on an arm on
said shaft. This cam lies outside the path of movement of the bowl 4, when the
switch V is in position to guide the paper and wrapper onward with the core, but
on the rocking of the shaft 21, to carry the switch inward for the delivery of the
wrapped paper, it is carried inside the path of the bowl, so that the latter rides
upon the outside of the cam, and the shaft 46 is rocked against the tension of the
spring on rod 3, to open the gripper for the release of the head of the sheet and
wrapper.
A circular cam 48 extends from the cam 47 to the opposite side of the cylinder,
and is so positioned that the bowl 4, during the first rotation, rides upon the
inner side of said cam, and the gripper is held in its closed position by spring
pressure.
When the bowl 4 passes off the outer side of cam 47 in opening the gripper,
however, it passes onto the outer surface of the circular canı 48, as shown in
Figure 9, and runs upon. this outer surface during the rest of that rotation, and
until the gripper is in position to seize another sheet, when the bowl 4 passes off the
point of the cam 48, into the position shown in Figure 8, and the gripper is closed
by the spring on rod 3 in the usual manner.
It will be understood that, with this construction, the tapes E, E, N, need not be
used, but the paper and wrapper are held by the grippers until they are seized
between roll H and cylinders C, D, as shown in Figure 9, a second series of
delivering tapes L' extending from roll H to delivering roll I being provided.
One or more tapes extending between rolls O, H, and corresponding to tapes N in
the constructions previously described for securing the proper feed of the wrapper,
may be used, however, if found necessary in any case.
In Figures 11 to 17 is shown a construction in which the core is withdrawn for

page_text: the delivery of the paper to the switch, enabling the use of a wrapper overlapping
the ends of the cylinder, and this construction will now be described.
The cylinders C, D, forming the core, and carried by the shafts 111, 112, as in
the construction previously described, are enclosed within sleeves C', D', having
hubs c, d, splined to the shafts 111, 112, so that the shafts 111, 112, rotate with the
sleeves C, D, while at the same time the cylinders C, D, and shafts 111, 112, are-
free to move longitudinally in the sleeves, so as to project therefrom for seizing the-
paper during wrapping, and to be withdrawn within the sleeves for the release of
the wrapped paper for delivery.
With the cylinders C, D, and sleeves C, D', co-acfs a single belt E, extending
partially about the cylinders from the side on which the paper is received, this.
belt being of sufficient width to extend between and over the sleeves C, D, and.
being supported and guided as the belts E in the construction previously
described.
The arrangement of the rolls G, H, I, K, M, and the short delivery belts L
coacting with the belt E rearward of the wrapping mechanism, is substantially the
same as previously described, but the arrangement of feeding devices on the
opposite side of the core; and of the guides and pasting mechanism, are varied.
On the opposite side of the core from the belt E, are mounted a series of rolls or
discs S. in place of the rolls S, T and belts R of the other construction, and the
guides U are carried by a rock shaft, and, at their rear end, carry the switch V.
A second series of guiding fingers P2, extending rearward from and between the
fingers forming the switch V, are preferably used, so as to secure a complete.
continuous guide when the switch is in the position shown in Figure 17, and lying
within the circumference of, but extending rearward of, the belt rolls M, so that
this guiding may be continued until the paper is securely grasped between the.
belts E and L.
.
The paste may be applied to the rear end of the wrapper, as previously
described, but the paste is shown as applied to the rear end of the wrapper before.
the latter reaches the wrapping mechanism, paste fountain W, fountain roll X, and.
rotating paster Y, being mounted in proper position to apply paste to the wrapper-
against a roll Q, which roll co-acts also with a series of guides P³, to aid in
advancing the paper to the rolls G and O, as shown in Figure 17. The paster Y
is constructed to apply paste only to the portions of the wrapper between the
guides P, so that the pasted portion of the wrapper will pass forward out of
engagement therewith, but will be brought into contact with the wrapper as the
leading ends of the paper and wrapper pass the guides P, on the second rotation of
the core.
The operating parts of this machine are driven from the main driving shafts Z..
by the following connections:-
The hubs c, d of the sleeves C', D', are provided with gears 113, 114, which.
engage respectively gears 115, 116 carried by the shaft of roll G, and the core is
thus driven. The roll G carries, also, at the end outside the gear 115, a gear 117,
which engages a gear 118 on the shaft of roll O, and the roll O is driven from the
main driving shaft Z by gear 119 on the main driving shaft, engaging gear 118..
The belt rolls M and belts L are driven from the main driving shaft Z by gear 119,
intermediate 120, and gear 121, on the shaft of roll M, and this shaft, in turn, ..
drives the shafts of rolls S by gears 122, 123, at the opposite side of the machine
from the gears 120, 121. The shaft of roll O carries, outside gear 118, a small
gear 124, which engages a larger gear 125 on the shaft of roll Q, so that the surface.
speed of the roll Q is the same as that of the roll G, and the paster Y is driven by
a small gear 126 on the shaft of roll Q, engaging a gear 127 on the shaft of the
paster, and gear 127, in turn, drives the fountain roll X through gear 128.
The cylinders C, D, are moved longitudinally by the following means:-
The main driving shaft Z carries, at its opposite ends, cams F, provided with
cam grooves, in which run bowls carried by levers 129 pivoted on the frame, and
at their opposite ends provided with bowls running in grooved collars 130 carried

page_text: by shafts 111, 112, so that as the cams. F rotate with driving shaft Z, the
cylinders C, D, are advanced and retracted in proper time for the receipt and
delivery of the paper. The switch is carried by the rock shaft 131, mounted on
the side frames A, B, and carrying inside the frame B a crank arm 132 connected
by a pitman 133 with a bell-crank lever 134, pivoted on the frame B, the other
arm of which lever carries a bowl which rides in a cam groove in a disc 135 carried
by the main driving shaft Z, inside the frame, so that the switch is thus moved
positively by the cam in both directions.
The operation of this machine is substantially the same as that of the construction
previously described, and will be understood from the drawings without further
description; Figures 16 and 17 showing the positions of parts on the first rotation
and in delivering the paper on the second rotation.
The cutting away of the cylinders C, D, at their inner ends, to form projections a,
by which the paper and wrapper are gripped against the belt E, is an important
feature, in conjunction with the withdrawal of the cylinders, as it enables the
wrapper to overlap upon the cylinders, and thus be of such length as to protect the
edges of the paper,-this special form permitting the switch to throw the wrapper
in without tearing the edges, and the wrapper to be drawn off the core during the
withdrawal of the two parts C, D, which is commenced simultaneously with the
movement of the switch V, so that as the flap of the wrapper passes from the core,
the cylinders C, D, are fully withdrawn, and the wrapper left free, although of the
same width as the paper. The core need not be cut away at the edges as shown,
if the wrapper is of a width less than the distance between the two parts of the
core, or even with a wrapper somewhat wider than this distance, if the parts of the
core are withdrawn at such a time as to enable the loose parts of the wrapper to be
carried inward by the point of the switch, as the paper is led off, but the construction
shown will be found more efficient.
It will be understood that many modifications may be made in the construction
shown by those skilled in the art, without departing from the invention.
While the invention has been described as applied to wrapping newspapers and
other publications, it will be understood that the machine may be applied to
wrapping other articles which can be rolled into cylindrical form, and that such
uses are within the invention, and the term " paper is used in the claims to include
such other articles.
"
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
from abroad, I declare that what I claim is :-
1. The method of wrapping newspapers and other publications, which consists
in winding the paper and wrapper upon a core of less length than the width of the
paper, with the wrapper applied to that part of the paper not supported directly by
the core, leading off the paper and wrapper from the core with the rear end of the
wrapper overlapping the first layer of wrapper upon the paper, and pressing down
the overlapping portion of the wrapper for pasting, substantially as described.
2. The method of wrapping newspapers and other publications, which consists
in rolling the paper and wrapper into a cylindrical form, with the circumference
greater than the length of the paper, leading off the paper and wrapper from the
rolling space by their leading ends, with the rear end of the wrapper overlapping
