Improvements in Apparatus for Cutting and Folding Paper
and the like.
I HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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:--
A cutting and folding apparatus embodying this invention in its entirety
is more especially intended to be used for taking sheets on each side of which
several pages have been printed, cutting said sheets severally into a given
cut number
or sections, assembling each
number of shorter sheets
of shorter sheets or sections in a pile and while so assembled folding
them all together in lines parallel with their so cut edges, and finally slitting
the said assembled and folded sheets or sections at right angles to their folds
and cut edges to produce a number of signatures each containing a suitable
number of leaves for binding. Some of the features of the improvement are,
however, applicable to cutting and folding machines organized otherwise than
as hereinabove mentioned.
SO
I have illustrated in the accompanying drawings and will proceed to describe
a machine in which my invention is embodied and will afterwards point out
its novelty in the claims.
Figure represents a side elevation of the apparatus.
Figure 2 a plan of the same.
Figure 3 a longitudinal vertical section in the line 3, 3, of Figures 2 and 5.
Figure 4 a longitudinal vertical section in the line 4, 4, of Figures 2 and 5.
Figure 5 a front elevation omitting the feed-board.
Figure 6 a vertical section of the feed-controlling and cutting devices taken
at right angles to Figure 5 in the line 6, 6 of that figure.
Figures 7 and 8 are detail views which will be hereinafter explained.
Similar letters of reference designate corresponding parts in all the figures.
A designates the framing of the apparatus. BC are two rotary cutter shafts
mounted in bearings in or on the framing A and carrying the blades be of which
two pairs are represented one of each pair being mounted in a cutter stock
consisting of heads 1* on the shaft B and the other in a cutter stock con-
sisting of heads C* on the shaft C. The said cutter shafts are geared together
to cause the edges of their blades to move at the same speed by two pairs of
gears BC fast upon them and the lower one B is furnished with another spur
5 gear D through which it receives rotary motion from the driving shaft E of
the apparatus, the said shaft E being furnished with a spur gear E (Figures 1
and 5) which gears with a gear E2 running loosely on a fixed stud a and gearing
coin 27

page_text: with the gear D. The cutters may be such as are now in use and therefore need
no further description, but in order to counteract the tendency, which is com-
mon in the operation of such cutters, of the edges of the paper from which the
sheets or sections have been cut by them to stick or to move downwards with
the edges of the lower cutters after the cutting has been performed. I have
applied to the said cutters and their heads B* the devices which are described
as follows with reference to Figures 1, 2, 5, 6, 7, the last mentioned of these
figures being a side view including all of the said devices detached from the
other parts of the apparatus, the cutter head B* only being shown in dotted
outline.
BB3 are light rock-shafts, one for each cutter b mounted parallel with their
shaft B in bearings in the cutter heads B* and furnished with cutter clearing
fingers the points of which in their normal condition are held against the
front of the cutters b just within their edges by springs attached to their
shaft B. These rock-shafts 13 are each furnished at one end with an arm b
at the end of which is a roller which, every time the respective cutter b has
passed by the corresponding cutter & after the cutting operation, runs in contact
with a stationary cam B carried by a bracket 135 secured to the framing. In
so running against this cam the arm is forced outward from the center of
the cutter shaft and caused to similarly move the fingers and thereby to so
press them outward against the edge of the paper from which a sheet has been
cut as to lift or prevent the descent of said edge and so carry it forward a
short distance that it may present itself properly to such carrying devices as
may be employed to carry it forward to be folded.
is a feed board, such as is commonly used in printing machines, upon which
the sheets to be cut into sections and folded are placed. In front of the feed-
board there are arranged behind the cutter shafts and cutters, two feed
rollers de (Figures 5 and 6) for receiving the sheets from the feed-board and
carrying them to the cutters. The lower feed-roller d is carried by a .shaft
working in fixed bearings in the framing and furnished with a spur gear d,
and said roller is driven constantly by the spur gear D hereinbefore men-
tioned on the lower cutter shaft B, through an intermediate gear f (Figures 1
and 5) which works loosely on a fixed stud fi and gears with the said gears
and D. The upper feed roller e is a drop roller and is driven by the lower one
through the friction of the paper passing between them, the journals of the
said roller being hung in arms e which are secured to a rock-shaft which
works in bearings in the framing A. To produce the rise and fall of the roller e
the said rock-shaft is furnished with an arm to be operated upon by a cam g
Figures 3 and 5, on a short shaft g which works in a stationary bearing g² on
the framing, the said shaft g being furnished with a gear on its outer end
through which it is driven by a gear G¹ on a shaft G which works in fixed
bearings in the framing and which is furnished with another gear G2 through
which it derives motion from the same gear E before mentioned on the driving
shaft E. through which the cutters and the feed roller dare driven. The con-
nection between the cam and the arm e² consists of a rod g and an attached
yoke which engages with the cam. The rock-shaft 2 also carries a stop
gauge consisting of a rod carried by arms on the rock-shaft and having
attached to it curved fingers 2. These fingers are projected upwards in front
of the feed-board when the drop rollere rises and are depressed when the drop
roller descends. In order that the said fingers 2 may come up in front of the
hite of the feed rollers, the roller d is grooved for the passage of the said fingers.
On the top of the feed-board near one side thereof there is a laterally recipro-
cating jogger H for the purpose of bringing the sheets to a proper position
laterally when placed upon the board against the gauge fingers 2. This jogger
is operated by a cam H on the short shaft g¹ through a lever H2 which works
on a fixed fulcrum H3 under the feed-board and which is connected with the
jogger by a pin H which works through a slot 40 in the board.

page_text: The folding devices represented for folding at one operation parallel with
their cut edges the several sections into which the original sheets are severally
cut, comprise as shown in Figures 2, 3 and 4, folding blades I which are
parallel with the rollers i j and mm*, and stationary tables consisting of slotted
plates J arranged below the level at which the cutters be meet and operate and
the direction in which the meeting
having an inclination downward in
cutters be move. There are two sets of said devices arranged one in advance
of the other in the direction of the above mentioned movement, one set for
the purpose of folding the several sections into which every other larger or
longer sheet fed from the feed-board F is cut by the said cutters and the other
set for the purpose of folding the corresponding sections into which the inter-
The said blades are carried by the arms I' of
vening larger sheets are so cut.
The
rock-shafts I2 which are arranged in bearings in or on the framing A.
said rock-shafts derive their necessary movement for operating the folding
blades from two similar cams I on the shaft G hereinbefore mentioned, the
arrangement of said cams on the said shaft being such that the said blades
operate alternately at regular intervals, once for every sheet presented, to the
cutters. The connections between the cams 13 and the rock-shafts 12 consist,
as shown in Figure 4, of yoke rods 1 engaging with the cams and connected
with downwardly projecting arms on the rock-shafts.
Forward of the cutters be there is arranged a pair of rollers i j fast on shafts i* j*
running in bearings in or on the framing, said rollers having a surface speed
corresponding with that of the feed rollers dc. The feed rollers de and the
rollers i may be considered as parts of one set of carrying devices for pre-
For carrying the sections forward to the
senting the sheets to the cutters.
folding devices I employ two sets of endless carrying tapes k, l, the tapes k

is a number of short sections as shown in plan in Figure 2, in which the top
sections there are narrow rollers (see
roller is omitted, and between these
Figure 2) which are loose on the shaft * on which run the tapes which also
run on and are driven by the lower one m of a pair of rollers mm* which run
in bearings in or on the framing. These rollers m m* tapes & and loose rollers i¹
5 constitute a set of carrying devices independent of the set constituted by the
rollers de and ij and they have a greater surface velocity than the latter
rollers so that the sheet sections as they are successively received from the
and the rollers mm have their movement accelerated.
rollers by the tapes
Consequently the cut rear edge of each is separated from the corresponding
O cut front edge of its successor far enough to obviate all liability to interference
between the successive sections on their way to the folding devices. The tapes/
which are supported in fixed bearings and have top
run on rollers P
rollers * and * applied above them.
Between the tapes and the first folding plate or table J, that is to say the
5 one nearest the cutters be, there is an intermediate set of carrying tapes o
which run on the same roller m with the tapes k and on a roller o so arranged
in fixed bearings as to give said tapes o a downward inclination. Between the
which
tapes and the second folding plate or table J there is another and similarly
the same
arranged set of intermediate carrying tapes o
on a roller above the said folding
50 roller with the tapes and
plate. Each of the two rollers has applied to it a top roller o*. The
rollers PP** and o¹ o* all rotate with the same surface velocity as the
rollers mm*.
run on
The tapes and I have respectively arranged above them stationary trans-
55 verse guard rods to which are attached guards which confine the sheet
sections flatly upon the tapes. Between the rollers pp* there are arranged
stationary guide fingers s attached to a fixed transverse bar for the purpose

page_text: of preventing the downward passage of the cut sheet sections over the tapes
to the first folding plate J except when so directed by the movable switch which
will be presently described. Above each of the tape rollers there is arranged
a stationary transverse bar which carries fingers u for supporting the sheet
sections beyond the bite of the rollers oo. The rollers p and o' are grooved
circumferentially for the passage between them and their respective top rollers
of the fingers s and u. In front of the upper and rear parts of the folding
plates Jin rear of the slots provided therein for the blades I there are fixed
guide fingers attached to a stationary transverse bar ; and below and in front
of the parts of the said plates below the said slots there are fixed guide
fingers attached to a stationary transverse bar w¹. Near and parallel with
the lower edges of the folding plates J there are attached to the faces of said
plates stops to stop the sheet sections in such positions that the .blades will
fold them midway between their upper and lower edges.
The switch before mentioned (see Figures 2 and 4) is for the purpose of
directing downward to the first folding plate the sheet sections cut from every
sheet as they come from the tapes and rollers mm* and of letting the sections
from the intermediate or alternate sheets pass by the first set of tapes o and
over the guide fingers s to the rollers * tapes and rollers qq, thence to
the second set of tapes and rollers * and to the second set of folding
devices. The said switch consists of fingers which are affixed to a rock-
shaft working in fixed bearings on the top of the framing behind the roller me*
and which extend over the said roller, preferably through circumferential
grooves therein. The raising of this switch to let the sheet sections pass by
the first set of tapes and the guides and the lowering of the same to the position
shown in Figure 4, to direct the sheet sections downward under the points of
the guide fingers s and on the tapes leading to the first folding apparatus
are performed by a cam K (see Figure 6) on the shaft G acting through a yoke
rod K connected with an arm K on the rock-shaft t¹.
In order to insure the delivery of the cut sheet sections to the folding plates J
so that they will properly and evenly arrange themselves one upon another
thereon, I provide as shown in Figures 2 and 4, above or in front of each set
of tapes o and its corresponding supporting fingers u, a presser consisting of
a rock-shaft " arranged in fixed bearings and having attached to it fingers P
corresponding in number with the said supporting fingers and arranged exactly
over them. These presser fingers pass, as shown in Figure 4, through circum-
ferential grooves in the rollers o* and project beyond the rollers oo* far enough
beyond the supporting fingers u for their ends to overlap the upper or rear edge
of their respective folding plate J, the said ends being turned downward over
the ends of the supporting fingers. The said fingers Pare, except just while
the front edge of a sheet section is passing from the bite of the rollers o¹ o* to
the folding plate, held up clear of the folding plate by means of a spring 12
applied between an arm 12 on the rock-shaft P and a bearing 13 on the framing,
but while the front edge or head of the sheet is so passing, the said fingers are
depressed by the action, on the rock-shaft arm 12, of a cam 13 which is carried
by a gear turning on a fixed stud P³ and to which rotary motion is imparted
as hereinafter described. The object of this depression of the fingers, which
owing to the form of the cam 13 and the lively action of the springs 12 is only
instantaneous, is to hold down the rear portion of each preceding sheet section
flat upon the inflexible surface of the folding table and prevent it from curling
up at the moment while the head or front edge of the succeeding sheet com-
mences to overlap it, and so obviate the possibility of the succeeding sheets
passing under or being interfered with by the preceding ones. This operation
may take place either before or after the preceding sheet arrives at the stop,
and if it should take place before, the temporary arrest of the preceding sheet
thus produced will be only instantaneous, and the former sheet would pass
onward to the stop after the rise of the presser fingers.

page_text: In order further to insure the passage of the heads of the sheets over the
ails of their predecessors the folding tables J are set as shown in Figure 4,
ith their faces a little below or behind the bite of the rollers o' o* and the
ath of the carrying surfaces of the tapes o, or in other words, the carrying
urfaces are arranged in a plane above the plane of the folding table.
Under each of the folding plates J there are arranged in suitable fixed bearings
inching rollers LL between which the sheet sections partly folded by the
assage of the folding blades through the slots of the folding plates J are
riven by the said blades and by which the folds are completed. Under each
pair of pinching rollers are arranged in suitable fixed bearings two parallel
shafts M M which carry at equal distances apart one or more pairs of circular
slitting cutters NN between which the sheet sections which have been folded
together are carried by the pinching rollers and cut at right angles to their
folds at as many places as may be necessary to produce the number of similar
signatures desired.
The rollers ij, which it has been before mentioned are driven with the same
surface velocity as the feed rollers de corresponding with the speed of the
cutter edges, are represented by a bevel gear 14 on the feed roller & through
a short side shaft 15 shown in full outline in Figures 2 and 5 and in dotted
outline in Figure 4, arranged in fixed bearings 16* outside of the framing A
and carrying two bevel gears 16, 17, one of which gears with 14 and the other
with a bevel gear 18 on the shaft of the roller i. The rollers are geared
together by spur gears 19, 20, on their respective shafts.
The accelerated rollers mm*, the tapes and all the other tapes and rollers
for carrying the cut sheet sections as well as the presser cam 13, are all driven
or operated through a long side shaft Q shown in full outline in Figures 2
and 5 and in dotted outline in Figure 4 which runs in fixed bearings 21 outside
of the framing A and which derives motion from the main shaft E through
a pair of mitre gears 22, 23. This shaft Q gives motion to the upper pinching
rollers L of the two folding apparatus through a mitre gear 24 on the said shaft
and a corresponding mitre gear 25 on the shaft 26 of each of said rollers L,
and from the said shafts 26, the rollers mm*, o¹o*, gq* and their respective
carrying tapes derive motion by gearing as follows, which is illustrated com-

a gear 31 which gears with the cam gear l' and drives the presser cam 13.
This gear P gears with and drives a gear 32 on the tape roller in and so drives
the said roller and the tapes k. The rollers m m* are geared together by gears 33
0 on their respectivo shafts; and in like manner, as illustrated in Figures 2
and 3, the rollers p*, the rollers * and those LL are respectively geared
each with its fellow, those pp by gears 34, those qq* by gears 35 and those LL
by gears 27. The shafts MM of the slitting cutters NN are geared together
by pairs of gears 37 and one of each pair is geared with and driven by one of
5 the gears 28 before mentioned. The rollers o* carries a gear which gears
with a gear 2 on the roller p and so drives the 'rollers pp and the tapes 7.

and for that purpose will assume that the gear D on the cutter shaft B through

follows;
The apparatus having all its parts in motion as herein before described, the

page_text: sheets to be cut and folded are deposited one at a time in any suitable manner,
as by hand, on to the feed-board, and while the gauge fingers and the drop
rollere are raised the so deposited sheet is pushed forward between the rollers de
to the said fingers. The said fingers and the drop roller being then depressed
the sheet is seized by the rollers de and carried forward to and between the
cutters by which it is cut into the determined number of sections (four in the
present case) which are successively carried forward by the rollers ij and thereby
deposited upon the tapes on which they pass to the rollers mm*, the move-
ments of which and of the tapes being accelerated produce the separation of
the several sections as herein before described. In this separated condition the
sections of one sheet, while the first switch is depressed, are directed to the
tapes o from which they are taken by the rollers oo* and deposited on the first
folding plate J down which, while the presser l' is periodically raised, they
successively slide and drop one after the other upon its stop a. The next fol-
lowing sheet is fed and cut into sections in the same way and its sections are
carried forward in the same way. with the accelerated movement; but before
the first of said sections arrives at the switch t, the latter is raised to allow the
said section to pass by it to the rollers p*, tapes /, rollers gq* and the second
set of tapes and rollers oo*, and the said switch continues raised while all
the sections of the last mentioned sheet have been deposited on the second folding
plate, after which the switch is again depressed to direct the sections of the
next following sheet to the first folding table, and in this way the operation
proceeds, the cut sections of every other sheet going to one and those of the
alternate intervening sheets to the other folding table. When all the sections
of a sheet have been deposited on either folding table its folding blade drives
it in folded condition through the slot in the table and between the pinching
rollers LL which complete and sharpen the fold and carry the so folded sections
between the slitting cutters NN by which they are slit into signatures, the
manner of which depends upon the number of slitting cutters employed.
I will now proceed to describe the provision for cutting sheets of different
sizes which is illustrated in Figures 1 and 2, partly in Figures 4, 5 and 6 but
particularly in Figure 8, which is a diagrammatic side view in which all the
parts involved in said provision are represented but of the gears only the pitch
lines are shown.
It is obvious that, at the time of cutting, the edges of the cutters be should
move at the same velocity as the surfaces of the feed rollers de. It is also
obvious that for cutting sheets into a given number of sections the length of
paper requiring to be fed during each revolution of the cutters is greater for
a longer than for a shorter sheet. In order therefore to adapt the same machine
to the cutting and folding of sheets of different length, 1 provide for feeding
the greater length of paper during each revolution of the cutters by simply
changing the gear herein before mentioned on the feed roller d for a smaller
one so that the rollers de and ij are caused to run at a greater speed and the
paper is caused to be thereby fed and carried at a greater speed; and in order
to correspondingly increase the speed of the cutters at the time of cutting with-
out increasing the number of 'their revolutions, I provide for the temporary
acceleration of their movement during those portions of each of their revolu-
tions in which they are actually engaged in cutting. This temporary accelera-
tion of the cutters we provide for in the following manner. Instead of making
the gear D (through which the cutter shafts, the feed rollers de and rollers ij
have been described as driven) fast on the cutter shaft B, I make the said gear
loose on the said shaft B and provide on the outside of the said gear D, as
shown in Figures 1 and 8, a projecting pin 29*, and secure fixedly upon said
shaft an arm 30* against which the said pin may act directly to drive the shaft,
and I also attach to the said arm by a pivotal connection 31*, a rod 32*, around
which is a coil spring 33* which acts between a shoulder 34* on said rod and

page_text: 5
guide 35* for the said 'rod provided on the gear 1 to press
Fard the pin 29*. This permits the cutter shaft to run forward a certain
tance independently of the gear D and thus permits the speed of the cutter
afts and cutters to be accelerated during a certain portion of their revolution.
upper cutter
make this temporary acceleration correspond with the speed of the rollers de
d rollers ij, there is provided on one of the gears C on the
aft two toothed sectors 36* the teeth of which correspond with those of the
ars C and which are adapted to gear through intermediate gears 37ª, 38
ranged loosely on fixed studs 37* and 38* on the framing with a second gear *
the shaft of the feed roller d.
If the gear 2 before mentioned on the feed roller shaft and the gear d*
st mentioned should have the same number of teeth which would be the case
hen sheets of the smallest desired length are to be cut, the arm 30* on the
utter shaft B and the pin 29* on the gear D would remain in contact and the
utter shafts and the feed rollers de and rollers i would operate as though
he gear D were fast on the cutter shaft B as previously described, but when,
or the cutting of longer sheets the gear is changed for a smaller one as
ndicated by the dotted pitch circles of 2 and d* in Figure 8 and the feed
ollers de and the rollers ij are driven at a greater velocity. the cutter shafts
re still driven by the action of the pin 29* of the gear D during the greater
ortion of each of their revolutions and without any increase of velocity; but
just before either pair of cutters be comes into operation one of the sectors 36*
comes in gear with the gear 38 and thus the cutter shafts, while the cutters are
in operation, are driven through the feed roller at the accelerated velocity
During this acceleration the

arm 30* runs away from the pin 29* but after the cut the sector 36* having
passed clear of the gear 38 permits the spring 33* to press the arm 30* back-
wards until it is overtaken by the pin 29* which then drives the cutter shafts
until the sector comes into gear with 38 for the next cutting operation. In
order to provide for the keeping of the gear 2, whatever the number of its
teeth. properly in gear with the gear D. the shaft f¹ (see Figure 1) which
carries the loose intermediate gear f is adjustable higher or lower in a slot f
shown in dotted outline in that figure.
It may be observed that the acceleration of the several carrying tapes and
their driving and supporting rollers herein before described relatively to the
speed of the feed rollers de and rollers ij. must be such that the said tapes
and their rollers will have a velocity greater than that which the feed rollers de
and rollers i have for feeding the longest sheets in order that the several
sections cut from each sheet may have their adiacent cut edges separated as
herein before described, the velocity of the several tapes and their rollers being
invariable relatively to that of the driving shaft E of the apparatus.

tion and in what manner the same is to be performed, as communicated to me
