Improvements in Folding and Wrapping Machines.
I, HENRY EDWARD NEWTON, of the Office for Patents, 6, Bieam'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.-
This invention relates to machines for folding and wrapping sheets of paper
or other material.
The especial object of one part of this invention is to provide an improved
mechanism of that class used for wrapping newspapers and other publications
for mailing, but the construction embodying this pait of the invention is applicable
also in folding without wrapping
More particularly, the mechanism of this part of the present invention is of
that class in which the paper or other article to be wrapped is advanced to a
carrier, with the wrapper lapped over the leading end or edge of the paper, and
the other end of the wrapper projecting behind the paper sufficiently to overlap
upon the first layer of wrapper on the paper, and then transferred by the carner,
and its rear end with the flap of the wrapper tuined about it delivered between
pressing surfaces, by which the flup is pressed down upon the layer of wrapper
on the paper, and thus secured by paste pieviously applied
According to the present invention, the carrier and the pressing devices are
caused to approach each other after the paper and wapper have been fed into
the canie, so as to cause the paper to be positively entered between the pressing
surfaces, which are preferably provided by a pair of 1olls forming pressing and
delivery devices The canner and these rolls are preferably caused to approach
each other by giving them a movement of 1otation in opposite duections, and
this is preferably an oscillatory movement, that is, a movement of partial notation
and back again, the centies about which they oscillate being so positioned, and
their movement being such, that they simultaneously move toward a line extending
between then centies of oscillation To this end, the care and the pau of
pressing and delivery rolls are preferably mounted on shafts which carry inter-
meshing segmental gears, whereby the requned relative movements of the carrier
and the pressing and delivery rolls are secured
This part of the invention comprises further various features contributing to
the successful operation of wrapping, which will be hereinafter specifically pointed
out in the claims, after a detailed description of a construction embodying the
various features of the invention
This wapping mechanism may be fed by hand, or any suitable devices may
be provided to automatically feeding the papers and wrappers at the proper
intervals A machine embodying this part of the invention may be designed to
wiap papers which have been previously folded to the desired size for wrapping,
or the papers may be folded by mechanism embodied in, and forming part of,

page_text: the machine, either entirely, on after being first partially folded in any suitable
manner, but preferably by the folding machine which also forms a part of the
present invention, on the wrapping mechanism may be combined with the delivery
and folding mechanism of a printing press, as is customary with other forms of
wiapping mechanism now in use, suitable mechanism being provided for associating
the wiapers with the papers, so that the papers shall be advanced to the
wrapping mechanism, with the wrapper turned about the leading end of the paper,
and projecting behind the paper sufficiently to overlap on the layer of wiapper
on the paper, when it is turned about the end of the paper, in the further operation
of wrapping
The invention includes also a mechanism for folding sheets of aper or other
material, especially adapted for use in connection with the wrapping mechanism
above described, but which may also be used independently of this or other
wrapping mechanism This folding mechanism is adapted to fold a sheet delivered
to it either in its flat unfolded state, or wluch has been preliminarily folded,
and may be fed automatically or by hand, or may be combined with the delivery
mechanism of a pinting machine, as 18 customary with other forms of folding
mechanism.
In a machine constructed in accordance with this part of the invention, in
the preferied form, there is provided a thin interior plate about which the sheets
are folded by suitable lapping guides, and which has a nanow edge which
determines the final line of fold of the sheet, and an exterior bearer for co-operating
with the fold-formung edge of the interior plate, to advance the sheet longitudinally
of said edge, and which exterior bearer is preferably grooved to bend the sheet
on the fold line, about the fold-forming edge of the interior plate The interior
plate is preferably formed by a 1otary disk, or a plurality of such disks in line,
and the extenor bearer is preferably formed by a coresponding number, one or
more, of rotary disks, or wheels, preferably grooved
Other featuies of this part of the invention are found in combinations of parts,
too fully hereinafter described and specifically claimed, to need pieliminary
description
For a full understanding of the invention, a detailed description will now be
given of a complete folding and wrapping machine, and a folding mechanism
embodying, in their prefented form, the various features of the invention above
generally described, reference being had to the accompanying diawings, and
the features forming the invention will be afterwards specifically pointed out in
the claims

page_text: Referring to said drawings, and first to Figures 1 to 8, the various parts of the
wrapping machine, as here shewn, are supported by aide frames A, B, and are
arranged so that the papers being fed from a paper-feeding mechanism at the
rear end of the machine, are advanced through the folding devices to the
wrapping mechanism located at the forward end of the machine, wrapper feeding
mechanism being located in the upper forward part of the machine, and arranged
to feed the wrappers to be associated with the papers during the last fold of
the paper, and suitable pasting mechanism being provided
The machine, as shown, is intended to be supplied with newspapers partially
folded, as by the delivery mechanism of a printing machine or other folding
machine for delivery to carers, or for street or counter sale, or with other
periodicals on pamphlets, and is designed to fold such papers or other publications
twice, and to apply and secure the wrapper thereto The wrapping mechanism
proper will be first described, and afterwards a general description of the complete
machine shown in these figures will be given by following, in a general way, the
course of the papers through the machine
With regaid, first, then, to the wrapping mechanism proper -A carrier 10
receives the paper as it is advanced from the feeding devices, consisting preferably
of rolls 11 and 12, as shown, with the wrapper twined about the leading end
of the paper, and projecting behind the paper sufficiently to overlap on the layer
of wrapper on the paper, and transfers its rear end to pressing and delivery
devices formed preferably by a pair of rolls 13 and 14, simultaneously folding the
rearwardly extending flap of the wrapper over the end of the paper. The rolls 18
and 14 are preferably mounted to oscillate so as to approach the carrier for receipt
of the paper, and are preferably adjustable toward and away from each other,
to accommodate papers of different thickness For this purpose, they are mounted
to rotate in arms 17 and 18 carried by a rock shaft 15, the arms carrying one
of the rolls being fast on the shaft, and the other pair of arms being adjustablv
secured to the first pan of arms, as by a pin and a slot connection, as shown
at 19
The carrier is preferably formed of sade plates a and b, mounted on a shaft 20,
so that the caner may be oscillated back and forth between its receiving and
delivery positions, shewn in Figures 2 and 8 respectively After the papers have
been advanced by the rolls 11 and 12 into the carrier, the carrier is oscillated
toward a line extending between the shaft 20 and the rock shaft 15, and the
shaft 15 19 rocked so as to carry the pressing and delivery rolls 13 and 14
toward said line simultaneously with the movement of the carrier, whereby the
carrier and the pressing and delivery-rolls are caused to approach each other
as they move toward the position in which the pressing and delivery rolls receive
the paper from the carier
As the paper is transferred by the carrier after leaving the roll, 11 and 12,
the earwaidly-extending flap of the wrapper is turned over the end of the paper
by means of an abutment suitably positioned for this purpose Preferably the
carrer is, as shown, so positioned with ielation to the rolls 11 and 12, that one of said
rolls, 12, acts as an abutment to turn the flap of the wrapper over the end of the
paper, as it is moved past it by the carrier, and the wrapper is held in this
position during the further movement of the carrier by means of a guard, 16,
extending concentrically with the shaft 20 from the roll 12 toward the point at
which the aper is delivered to the pressing and delivery rolls
For the purpose of securing the proper relative movements of the carrier and
the pressing and delivery rolls, they are preferably moved through inter-meshing
segmental geais 21, 22, mounted on the shafts 20 and 15 respectively, which
gears are oscillated by a pitman 23 connected to one of the gears, as 22, and
carrying a bowl which runs in a cam groove in a cam disk 24 on the main
driving shaft 25
The pressing and delivery rolls 13 and 14 are provided with intermeshing
gears 26 on their respective shafts, and are preferably driven by a gear 27, free

page_text: to turn upon the shaft 15, and meshing with the gear 26 on the shaft of the
roll 14, and which gear 27 is driven by a gear 28 on the main driving shaft 25,
through an intermediate 29
It is desirable that the papers may be easily fed into the carrier 10, and easily
drawn out therefiom, when engaged by the pressing and delivery rolls, and that
the carrier shall hold the paper securely while transferring it from the feeding
devices to the pressing and deliver devices For this purpose, the carrier 18
constructed substantially as follows Its two side plates a and b are each
independently mounted on the shaft 20 by means of sleeves free to turn on taid
shaft, and are pressed toward each other by means of springs 30 and 31, carried
by a sleeve 32, which carries the segmental gear 21, said springs engaging
respectively a lug 34 extending from the plate a, and a lug 35 extending from
the plate b, the plates being prevented from moving toward each other beyond
a certain point by means of a stop 33, carried by the sleeve 32, and extending
between the lugs 34 and 35, carried by the side plates a and b. The side plates a
and 6 of the railler will thus be oscillated through the stop 83 and the springs 30
and 31, when the sleeve 32 is oscillated through the segmental gear 21, as will
be readily understood One of the sleeves carrying the side of the carrier,
18 provided with a backwardly extending lug 36, which, as the carrier approaches
its receiving position, as shown in Figure 2, 18 engaged by an abutment or
stud 37 on the fame of the machine, whereby the side b, of the carrier is moved
against the tension of the spring 31, whereby the carrier is opened to receive the
paper, the other side, a, of the carrier being held by the stop 33
Similarly, the sleeve carrying the side a, of the caruer is provided with a
backwardly extending lug 38, which, as the carrier approaches its delivery
position, as shown in Figure 8, is engaged by an abutment or stud 39 on the
frame of the machine, whereby this side of the carrier is moved against the
tension of the sping 30, to open the carrier for delivery of the paper The
stop 33, 18 of such a thickness as to allow the two plates of the carrier to approach
each other under the tension of the springs, so as to securely hold the thinnest
papers on which it may have to operate It will be seen that a carrier thus
formed will accommodate itself to papeis of different thicknesses without adjust-
ment
In order that the paper may be positively fed into the carrier, there is pro-
vided a feeding roll oi rolls 40, which, acting through openings in the side plate a,
of the caner, when the carrier is in its receiving position, as shewn in Figure 2,
engage the paper as it is advanced into the carrier from the rolls 11 and 12,
and feed it positively into the carrier against against a stop c, carried by one of
the sides, as a. A roll or rolls 41, are preferably carried by the other side
plate of the carrier, to co-act with the rolls, 40
The pressing and delivery rolls 13 and 14 are preferably sectional or grooved
rolls, to accommodate the ends of the side plates b, of the carrier, and of the
curved guard 16, which are preferably of such a length as to extend slightly
within the periphery of these iolls, in certain positions of the parts, as shown in
the various figures.
When the carrier is in its receiving position, as shewn in Figure 2, a paper
is advanced by the feeding 1olla 11 and 12, with the wrapper turned about
the leading end of the paper, and projecting behind the paper sufficiently to
overlap on the layer of wrapper on the paper, and enters the carrier, and is
engaged and further advanced by the feeding rolls 40, 41, against the stop
The cam 24 by which the wrapping mechanism is operated, 18 formed with a
concentric portion or dwell, whereby the cartier 18 held stationary in its receiving
position long enough to receive the paper Then, by the further revolution of
the cam, the carrier is moved about the shaft 20 in the direction of the arrow
in Figure 2, whereby, as the paper is carried past the periphery of the roll 12,
the wrapper is folded over the end of the paper, as shown in Figure 6.
As the carrier is further advanced about the shaft 20, the wrapper is held

page_text: turned over the end of the paper by the guard 10, until the parts approach the
position shown in Figure 7, where the pressing and delivery devices have come
into position to receive the rear end of the paper, with the wrapper tuined about
at Then, by the further movements of the parts, the carrier and the pressing and
delivery rolls approaching each other as they approach the line extending between
the centres of the shafts 20 and 15, the paper is positively entered between the
pressing and delivery rolls, the flap of the wrapper being further turned back
against the side of the paper by the roll 13, and the wrapped paper is diawn
out of the carrier by the pressing and delivery rolls, the carriei being opened
by the stud 39 engaging the lug 38, as the Jaits reach the position shewn in
Figure 8. Then, by the further movement of the cam 24, the pitman 23 is drawn
back, and the carrier and the pressing and delivery rolls are returned to their
former positions, as shewn in Figure 2, and the same movements are repeated
for the wrapping of each paper
The papers may be delivered from the rolls 13 and 14 into a suitable receptacle,
or onto a carrier belt, or in any suitable manner
A general desorption of the complete machine illustrated in Figures 1 to 8 of
the drawings will now be given
The paper is advanced from the paper-feeding mechanism by feeding rolls 50
and 51, over supporting guides 52 and 53, beneath a pan of folding rolls 54
and 55, a guard 56 being provided beneath the roll 55, to prevent the paper
coming in contact therewith, as it is fed forward beneath it A folding blade 60
18 arranged to be advanced between the guides 52 and 53 from beneath, to
engage the paper on the fold line, as it is advanced beneath the rolls 54 and 55,
to can the folded edge upward between said volls The folding blade is canned
by a rock shaft 61, by means of aus 62, and its movement 18 controlled by a
cam 63 on the main diving shaft 25, which engages a bowl 64 on a pitman 65,
which is connected to an arm 66 on the rock shaft 61, the cam being formed to
1ock the shaft 61, to draw the blade back after its folding movement, and so as
to allow the shaft to be locked by means of a spring 1od 67 connected to an
am 68 on the shaft for the folding movement of the blade
As the paper is advanced by the 1olls 54 and 55, its forward end is engaged by
a curved guide 70, and deflected around the roll 55, from which it is advanced
on feeding taj es 71 beneath another pair of folding rolls 72 and 73, the roll 72
and the tapes co-acting to feed the paper As the paper 18 advanced along the
tapes 71, a wrapper y, 18 fed down around the roll 72, so as to be advanced over
the tapes 71 above the paper, and with its leading end in advance of the paper
When the paper and wrapper have reached the proper position beneath the
1olls 72 and 73, the paper is engaged from beneath by a sectional folding blade 74,
which, advancing between the tapes 71, engages the paper on the fold line, and
caries the paper and wrapper between the rolls 72 and 73.
The folding blade 74 18 mounted and actuated similarly to the blade 60, being
carried by a rock shaft 75 by means of aims 76, and its movement being controlled
by means of a cam 77 on the main driving shaft 26, through a pitman 78 connected
to an aim 79 carned by the shaft 75, and carrying a bowl which is engaged by
the cam
The cam 77 18 formed so as to rock the shaft 75, to withdraw the
folding blade after its forward movement, and to allow the shaft to be rocked by
means of a spring rod 80, pivotally connected to an arm carried by the shaft for
the folding movement of the folding blade.
The parer, after being entered between the rolls 72 and 73 by the folding
blade 74, 18 tuined about the roll 73 by means of tapes 81 passing beneath the
roll 72, and up over the roll 73, with the wrapper turned about its leading end,
and projecting behind the paper sufficiently to overlap on the layer of wrapper
on the paper, when it is turned over the end of the paper in the further operation
of wrapping, as heretofore explained The paper is then advanced between the
tapes 81 and a guide 82 to the feeding rolls 11 and 12, by which it is fed to
the carrier, as heretofore described,

page_text: The wrapper y, 18 fed from a web supported in the upper forward part of the
machine between feeding and perforating rollers 85 and 86, from which it 18
advanced between the tapes 81 and other tapes 87, which tapes move at a greater
speed than the rolls 85, and 86, and tuin downward about a roll 88, where they
grip the wrappers, and separate them on the lines on which they have been
¡erforated The wiappers are then called down around the roll 72, to be
associated at the proper time with the papers as they are advanced between the
roll 72 and the tapes 71
Paste is applied to the rearwardly extending flap of the wiappe as the paper
and wiappe are being advanced to the tolls 11 and 12 by a rotating paster 90,
which received the paste from a fountain roll 91, mounted to rotate in a fountain 92
The paste is made sectional, to accommodate the tapes 81, and is timed to make
one evolution for each paper passing through the machine
The paper-feeding mechanism shown m these figures, for supplying the papers
to the machine, consists of a holder having sidewise adjustable sides 100, and
a front piece 101, which is adjustable vertically, to allow papers of different
thickness to be fed forward beneath it over the guide 52 The papers are
supported in the box thus formed, by means of a bottom, 102, formed of slats,
and which 1 voted near the forward or delivery end of the holder, and 18
lowered at intervals to allow the bottom paper to come in contact with a series
of sectional feeding rolls, 103, by which the bottom paper is fed forward, to be
engaged by the feeding rolls 50 and 51 The pivoted bottom of the box is raised
and lowered by means of a cam 101 carried by the main driving-shaft 25, and
which engages a bowl on a pitman 105, connected to one aim of a bell-crank
lever 106, the other arm of which lever is pivotally connected to one end of a
connecting rod 107, which, at its other end, 18 pivoted to the bottom 102
The various feeding rolls. and the paster 90 and fountain roll 91, are driven,
in the construction shown, from the main driving shaft 25, as follows
-
The
The folding rolls 54 and 55 are geared together by gears 110 and 111, and are
diven from gear 28 on the shaft 25 thiough intermediates 112 and 113
feeding 1olls 50 and 51 are geared together by gears 114 and 115, and are driven
by an intermediate 116 from the intermediate 113 The rolls 103 of the paper-
feeding mechanism are geared together by gears 117 and intermediates 118, so
as to rotate all in the same duection, and are driven from the gear 114 through an
intermediate 119 meshing with a gear 120 on the first of the rolls 10%. The folding
rolls 72 and 73 are geared together by gears 121, and are driven from the
gea 111 through an intermediate 122, and a second intermediate 123 meshing
with a gear 124 on the shaft of the roll 72 The feeding rolls 11 and 12 are geared
together by gears 125, and are driven from a gear 126 on the shaft of the
rolls 73 through intermediates 127 and 128, the intermediate 128 meshing with
a gear 129 on the shaft of the roll 11 The feeding roll 40 canes a gear 130,
and is driven from the gear 129 through an intermediate 131
The intermediate gear 127 is mounted on the shaft of the paster 90, and is of
such a relative size as to cause the pastel to rotate once for each rotation of the
main driving shaft 25 The fountain 1oll 91 carries a gear 132 meshing with
the gear 127 The paste shaft also cairies another gear 136, smaller than the
gear 127, (from which the wrapper-feeding and perforating rolls 85 and 86 are
driven though an intermediate 133, at the rate of one revolution for each revolu-
tion of the diving shaft 25, said iolls 85 and 86 being geared together by
gears 134, with one of which the intermediate 13.3 meshes An intermediate 135
meshing with the gear 124 dives the roll 88.
The gearing 18 properly timed so that the various feeding rolls and belts will
bring the successive papers into proper positions to be acted upon by the folding
blades as they are advanced under control of the cams on the shaft 25, to properly
associate the wrappers with the papers, and to advance the paper and wrapper
to the carrier at the proper time
The operation of the machine shown in Figures 1 to 8 as a whole, will be

page_text: readily understood from the foregoing description, and need not be further set
forth
It will be understood that the features of this part of the invention, as herein-
after set forth in the claims, may be embodied in machines differing widely from
that shewn and described for the purpose of illustrating the invention, and that
many changes and modifications within the claims may be made in the construction
of the wrapping mechanism without departing from the invention. It will also
be understood that the devices described herein as employed for folding over the
flap of the wrapper, may be used also for folding a paper or other article not
associated with a wrapper, and such use is within the invention
While the invention has been described as especially applicable to wrapping
newspapers and other publications, it will be understood that, machines embodying
the invention may be used for wrapping other articles for which it may be found
applicable, and that such machines are within the claims, the term paper
being used herein to include all articles and materials on which the machine is
adapted to operate

"
The folding mechanism forming a part of this invention, and which may he
combined with and arranged to supply the papers to the machine above described
in place of the paper feeding mechanism shewn in Figures 1 to 8, but which 18
shewn separately in Figures 9 to 14 for convenience, will now be described
In order to obtain a ready understanding of this part of the invention, the
particular embodiment of it in the primary folder shown in Figures 9 to 12
will first be described, and afterwards the modifications thereof will be explained,
as well as the mechanism of the secondary folder Premising that the object
18 to impart longitudinal folds to a sheet of material passed through this machine,
the devices thereof, and their action thereon, will be explained in connection
with a de cuption of the passage of a sheet through them
The sheet to be operated up on, either unfolded, or previously folded into a
pack, as a signature, 1s, while spread flat to its widthwise extent, fed into this
machine by means of endless tapes 200, 200, 200, 200, that extend inom calling
1ollers or pulleys 210, 220, the support of which they form a part being extended
sufficiently beneath the primary folder by means of conductors 230, 230, 230,
supported by cross 1ods 240, 250, to operate as a bridge sustaining the ingoing
sheet
A nallow feed 1oller, 200 co-operates with, and is driven concertedly with, its
companion feed roller 220 through pinions 360, 370, and its position 18 such that
the sheet is fed by contact neai its central line, which limited feeding contact
thus permits the sales of such sheet or folded pack to be upiaised from a point
more or less eat ward of the feeding nip of these rollers, and thus have imparted
to it a preliminary shaping or incipient folding, that enables the final lapping
of its sides to be performed without winkling, buckling, or
material.
crimping the
The 1olle 220 might be narrow like the roller 260, so far as its feeding
function is concerned, in which case its tape-carrying parts would be in the form
of simple pulleys
The primary folder comprises two aligned disks 300, 310, that rotate within
the folded material, and which have narrow edges for determining the line of
fold in the sheet in substantially a single line, and co-acting with the fold-
forming edges of said disks to advance the sheet tangentially, that is, longitudinally
of the portions of the edges of the disks engaging the sheet, are wheels 320, 330
preferably grooved, that bear upon the outside of the sheet on the line of doubling
or folding, each disk and wheel reciprocally constituting a sheet-propelling
mechanism that acts solely upon the line of doubling o folding Co-acting
with the propelling mechanism are aide lapping or turning guides 310, 350, that
cause the opposite sides of the sheet to be upturned and lapped on laud togethei
These guides are respectively aanged on opposite sides of said dishs 300, 310,
and practically, when vertically considered, have then inner or facing side paralleĺ

page_text: therewith, and they occupy such angles, horizontally considered, that they will
have one end extended within the plane of travel of the sheet near its middle
part, to intercept the same, and their opposite ends raised high enough to cause
the sides of the sheet to be guided and sustained between them and said disks
The sheets, as they are advanced between the disks 300 and 310 and the wheels 320
and 30, will thus be folded about the disks 300 and 310, and the dishs being thin,
and their edges being made very mariow, as before stated, as the sheets are
folded about such edges they will be folded at once on the line of the final fold
of the sheet, as it is advanced from the folder. The edges of the disks are thus
final fold-forming edges
These side lapping guides are preferably in the form of cones, whereby curved
surfaces suited to the work are presented for all portions of the sheet during
any position it assumes as the sheet travels onward, and has its aides gradually
lifted from a central point outward to its edges, so that these sides are progressively
turned upward and inwaid until they finally stand in parallel vertical planes,
and substantially in contact, in a position for delivery, it may be, to a secondary
folding apparatus, in which case the folding sheet stands substantially at night
angles to the folding mechanism of the same
During this folding operation, the doubled edge of the sheet remains in the
same horizontal plane in which the sheet has been fed, it being maintained
interiorly by the edge of the disks 300 310 by a narrow guide plate 110 extending
between them, and by a narrow extensor plate 130 projecting a distance beyond
the disk 310, and exteriorly by the conductors, in part by the table 120, the
latter constituting a bidge upon which said doubled edge beais
The plate 110 is curved to conform with the edges of the disks, 300, 310, and
18 hung in place by a bracket, and the plate 1:30, which 18 supported in like
manner, also has its rear edge similaily shaped, to conform with the disk 310,
and the two plates 110 and 130 with the disks thus practically form a continuous
nariow fold-forming edge on the inside, for the line of doubling or folding, which
extends far enough forward to perfectly co-act with the ade lapping guides
340, 350 Beneath the plates 130, a narrow table 120 is provided, to form a support
upon which the doubled edge of the sheet rests in a portion of its for waid travel,
said table being preferably provided, for a suitable distance, with a guiding
groove 100, in which the doubled edge of the sheet runs. This table 18 secured
by a rod 710 and a blacket 720, and from it supporting standards, as 730,
rise, to sustain the guides 340, 350. The grooved wheel 320 18 driven by a
toothed wheel 450, while the grooved wheel 330 runs freely, and the disks 300, 310,
are diven from the wheel 380, on the main shaft 800, through a tram of
wheels 390, 400, 410, 420, 430, 140, 450, and 460, that gears with the wheel 370,
which meshes with the wheel 360. The shaft of the latter carries a wheel 470,
that dives the wheel 490 on the shaft of the disk 300 by means of an inter-
mediate 480, and the wheel 490, in tuin, drives the wheel 510 on the shaft of
the disk 310, through an intermediate 500
It will now be understood that the flat sheet or pack delivered to this machine
by the tapes 200, will pass between the feed rolleis 260, 220, and the disk 300
and grooved wheel 320, that its body portion widthwise considered, or, in other
words, the sides of the sheet considered as the major portion thereof on each
side of its central point on line of fold, will be prevented from drooping, or
be guided by the conductors 230, so that its thin or limp leading edge will be
intercepted by the ends of the lapping guides 340, 350, at points close to the
said disk, and thereby cause its sides to ide up the inclined planes said guides
form and that, as its central line of folding or doubling is confined to a
horizontal plane of travel by the edge of the disks 300, 310, and guide
plates 110, 130, its sides will be bent upward, and that the bends in the sides
of the sheet will be made to such an extent, that such sides will be upturned to
a degree rearward of said disk, for the reason that the feeding rolls offer no
obstruction thereto, and hence, that the preliminary conformation of, or approxi-

page_text: mation to, the final folding, will be formed without rupturing the paper, or
causing it to cicase, buckle, or break As the sheet moves onward, its central
line or double edge will be confined to said houzontal plane by the edges of
the disks and the plates 110, 130, while its sides will be gradually and progessively
tuned upward by the guides 340, 350, until, when it leaves the said guides and
the plate 130, it will be longitudinally folded in its centre, with its sides practically
laid together.
In this folding operation, the bend of oi doubled edge of the sheet will conform
more or less, according to its thickness, to the groove in the wheels 320, 330,
which, as shewn, is quite wide as compared with the edge of the interior disk,
its smooth onward movement being thus aided in a manner that removes any.
cause for smutting, or injury from dragging, when that part of the paper is
being bent laterally, as well as moved outwardly, and this doubled edge will be
suitably embraced, supported, and guided in the groove 100, as the sheet passes
out of this primary folder.
It will now be obvious that, if both the disks 300, 310, and the grooved
wheels 320, 330, are driven, they will co-operatively form a rotating piopeller
acting to dive o cay the sheet onward by contact with that portion of it
constituting its line of doubling or folding, the disks acting on the inside, and
the grooved wheels on the outside thereof Although it is desnable to employ
the interior disks and exterior grooved wheels as shewn in Figures 9 to 12, & to
have one or all of both the disks and grooved wheels driven, it is, however, only
essential that the rotary or other moving member on one side of the sheet shail
be diven, and to coact with such duven sheet-propelling or driving member,
there may be provided a stationary bearer or support for the other side of the sheet
on the fold line, and this diving member may be either the one acting on the
outside of the inside, but the surface of whichever member is to act as a dive,
should be roughened, as by being milled or diaw-filed, and the surface that 18
to act merely as a support or bearer should be made as smooth as possible
The form illustrated by Figure 13 consists of a disk, 1, adapted to be rotated
as by a toothed wheel 2 This disk will run on the inside of the line of doubling
or folding, and, like the disks 300, 310, will have an extensor guide plate 3, which
is similai to the plate 130. The disk, in this instance, is the driver or propeller,
and has, by preference, a finely milled or diaw-filed edge, which 18 thus made very
slightly rounded
It will of course have exterior cooperating side lapping guides,
which may be like those, 340, 350, already described, and related to the disk 1
as they are to the disk 300
The bearer or support for the outside of the line of doubling or folding consists,
in this example, of a long narrow plate 4, whose beating edge is slightly curved
to form a smooth channel, which will conform to the rounded form of a doubled
o1 folded edge of paper, and its real portion is slightly curved downward, in
order not to impede the smooth introduction of the paper
In Fig 14, the grooved wheels, as 1, 1, 1, acting upon the outside of the
line of doubling on folding, constitute the propellers, while the support on the
inside of such line of doubling or folding is constituted by a narrow plate, as 7,
the lower edge of which 19 1ounded and made as smooth as possible Although
one of these wheels 1 will successfully operate, especially when it is provided with
a smooth grooved supporting plate or table similar to table 120 of the main
views, or the plate of Figure 13, it is preferable to provide a number of wheels
of small diameter, as 1, 1, 1, the grooves of which are preferably slightly milled
The plate, as 7, will have a curved end to cause the sheet to smoothly pass
beneath it, and the wheels 1, 1, 1, will be driven by toothed wheels, as 2, 2, 2,
or in any other suitable manner In this construction, there will be provided
side lapping guides, as those 340, 350, 01, of of any other suitable form
A single set of such devices as the foregoing will perfectly perform the opera-
tion of folding sheets of suitable size, but, when the sheets are largel, and con-

page_text: sequently longer, two or more propelling disks 300, 310, with intervening smooth
guide plates, as 110, will be needed
The secondary folder, which imipaits a longitudinal fold, parallel to that given
by the primary folder, may be of the same construction as the primary folder
As illustrated in Figures 9 to 12, it consists of two horizontally aanged
disks, 600, 610, hung in the branching aims of a bracket 810, and rotated by
means of wheels 620, 630, and an intermediate, 640, on a vertical shaft, 650,
that is actuated by means of bevel gears 660, 670, from the main shaft 800,
carrying the wheel 380. Cooperating with these disks, there are horizontally
airanged grooved wheels 690, 700, constructed and operating in all respects like
the wheels 320, 330, which are supported on vertical shafts 780, 790, journaled
in the frame-work
These disks and grooved wheels are so positioned that then contact with the
sheet will agree horizontally with the plane in which the sheet folded by the
primary folder travels, and then vertical position is the centre or other prede-
termined point of the fold which shall be imparted to such sheet
To the iod 740, which is aligned in a plane slightly at one side of the vertical
plane occupied by the folded sheet emerging from the primary foldei, a number
of side lapping guides 8, 8, 8, 8, 8, 8, are secured, and bent forward inward and
laterally (see Figure 9), to suit the curvature which a sheet will assume in being
gradually folded by having its sides bent toward each other, and finally lapped,
while its cential portion or line of doubling is confined by the disks 600, 610.
It will now be understood that the sheet, tolded longitudinally by the pumay
folder, and emerging therefiom in a vertical plane, will, fed by the driven fold-
ing mechanism of the primary folder, be entered directly between the disk 600
and grooved wheel 690, with its central portion embraced thereby, and that as
it 18 moved onward by the disk 600, and beyond the disk 610, its sides will be
intercepted by the guides 8, 8, and thereby be gradually tuned towards each
other, and that this turning will be progressively advanced toward houzontal
planes, until a lapping or folding is accomplished, while the doubled edge of the
sheet passes outward in a straight line on to the disk 610, between it and the
wheel 700, and on to the extensor plate 750 (which is like the plate 130), and,
finally, that the sheet will be doubled longitudinally, with its sides practically
lapped together embracing the plate 750 In this folded condition, the sheet
will be entered between the pressing rollers 760, 770, and be delivered
rollers are arranged to be positively notated by means of a train of wheels 820,
830, 840, 850, 860, the former being on the shaft of roller 770, and the latter
meshing with the wheel 380
Theso
As the sheet undergoing the final folding operation in the secondary folder
has previously received one or more folds, its double edge is sufficiently igid
to make it unnecessary to interpose a throat plate, like 110, between the
disks 600, 610, but the extensor plate 750 is desuable, so that the folded product
shall reach the pressing and delivery rollers in a true position for delivering,
and no distortion shall result from the pressing action of such 1olleis
This machine is adapted to fold vanous widths of sheets or folded packs, and
in order that the secondary-folder may he adapted to impart its fold in any
predetermined relation to the preceding fold, all of its fold-producing mechanisms
are arranged to be adjusted to the appropiate vertical position
Thus, the bracket 810 which supports the disks 600, 610, then wheels 620, 630,
and then diivei 640, which is splined on the shaft 650, is arranged to slide in
guides fixed to the frame, and provided with an adjusting sciew-shaft 160,
whose threaded portion turns in a nut fixed to the bracket
The grooved wheels 690, 700, are adjustable on then shafts 780, 790, by set
screws, though their hubs, and the guides 8 are all adjustable on the rod 740
br collars and set screws, while the extensor plate 750 has its supporting end
in like manner adjustable by a set sciew
One disk, one grooved wheel, and one or both of the plates 110, 130, may, with

page_text: lapping guides, be conjointly used where the nature of the work as to exactness
will permit it, as when a subsequent wrapping operation makes it less necessary
that accurate doubling shall be effected, and, in the same case, the grooved wheel
may be omitted; thus the disk 310, wheel 330, and the forward ends of conduc-
tois 230, may be removed, and the table 120 and parts beyond be moved rear-
ward, so that the disk 300 and wheel 330 takes the place of disk 310 and
wheel 330, o vice versa
It will be understood that this part of the invention, also, is not to be limited
to the exact construction shown, but that changes and modifications thereof
within the claims may be made, without departing from the invention
