Improvements in Machinery for Cutting and Folding Paper.
J, 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 :—
This invention is more especially intended to be used as an adjunct to a
perfecting printing machine for printing books, magazines or pamphlets, the matter
for numerous pages of which is printed by one impression on each side of the
paper. The invention is however, applicable to the cutting and folding of paper as
hereinafter described, independently of a printing machine.
To enable others skilled in the art to make and use the invention I have
illustrated it by drawings and will proceed to describe it in the complete form in
which it is to be applied to a perfecting printing machine for:
(1) Cutting into a number of sheets each of the successive portions of a continuous
web upon which a number of pages have been printed on both sides by one
impression on each side;
(2) Assembling the said sheets;
(3) Folding at one opération all the so assembled sheets;
(4) Slitting at one operation all the so folded sheets, into signatures ;
(5) And finally delivering the said signatures in condition ready to be stitched or
prepared for binding.

signatures are received and delivered from the cutting and folding devices.
Figure 10* a horizontal sectional view of parts of said delivery carrier.
Figure 1 a perspective view of mechanism for operating the carrier above
mentioned.
Figures 12 and 13 are diagrams of the two sides of a portion of a web printed
on both sides to form sixty four pages, illustrating how by the example of my
invention represented, the said portion is cut into four sheets which are after-
wards assembled and folded together, then all cut together to form four signatures
of sixteen pages each.
Similar letters of reference designate corresponding parts in all the figures.
A designates framing which may be and is represented as a portion of the framing
of a printing machine prolonged for the purpose of supporting the principal working
parts of the machinery which constitutes my invention. B is a horizontal shaft
mounted in suitable bearings on the framing and carrying gears from which the
cutting and folding devices derive their movements which are to be properly timed.
in relation to the revolutions of the form cylinders of the printing machine to which
the invention is applied. The shaft B may be driven by any suitable means but it is
represented as furnished for the purpose with a spur gear B₁ which is to be geared
through an intermediate gear B2 represented in Figures 1 by a dotted circle, with a
gear on one of the cylinders of the printing machine.
On the top of the framing A are the two side frames C for the support of the
carrier by which the printed web as it comes from the printing machine is taken to
the rotary cutters a 6 (see Figures 2 and 4) and thence forward toward the folding
devices. This carrier consists of two parallel endless toothed racks or chains D with
attached grippers c and c¹, the said chains running on supporting wheels D¹ which
turn freely on studs e secured in the side frames C, and the straight portions or runs
of the said chains between the said wheels running in the direction of the arrows
shown near them in Figure 2, on guide-ways e¹ on the said frames C. The said
carrier, except as to the spacing apart of the grippers lengthwise of the chains or
racks I) as will be hereinafter described, is substantially like carriers which have been
heretofore used in delivery and folding apparatus in connection with printing
machines. It is represented as driven continuously by two spur gears D2 (see
Figures 2 and 3) on the shaft B engaging with the teeth in the lower runs of the
chains, the speed corresponding with that of the surface of the printing machine
cylinders.
The rotary cutters consist of pairs ab of shear blades of a length equal to the
width of the web of paper. Two pairs are represented, one a of each pair being
carried by stocks E on a shaft E¹ and the other b being carried by stocks F on a
shaft F, the said shafts running in bearings on the framing A, one of the said shafts
being under and the other above the lower run, which is the operative run, of the
carrier. The upper one E¹ of said shafts is furnished with a spur gear E2 (see
Figures 1 and 3) through which it receives motion from a spur gear E3 on the shaft B,
and the lower one F¹ is furnished with a gear F3 (Figure 3) through which it derives
motion from a gear F (Figures 3 and 4) on the upper one E¹. The speed of the
cutter shafts is such that the edges of the cutters move at the same speed as the
carrier and the surfaces of the printing machine cylinders. The pairs ab of cutters
must be spaced apart at a distance equal to the lengths of web to be cut for the
sheets S (see Figures 12 and 13) and as in the example represented, the said sheets S
are to have a length equal to one quarter of the circumference of the cylinders of the
printing machine, and as there are two pairs a b of cutters, the cutter shafts must
make two revolutions for every one of the said cylinders. The grippers c c¹ are
spaced lengthwise of the carrier to correspond with the sheets S, so that there is one
gripper for each side of every sheet S.
The folding devices represented for carrying out my invention comprise, as shown
in Figures 2 and 5, folding blades G arranged crosswise of the carrier to operate

page_text: between the chains or racks thereof and stationary beds consisting of plates H
arranged below the carrier with an inclination downward in the direction of the travel
of the lower and operative run of the carrier. These plates have in them slots or
narrow openings into which the said blades enter. There are two sets of said devices
arranged one in advance of the other in relation to the lower and operative run of the
carrier, one set operating to fold the intervening alternate series of four sheets after
the sheets forming the series have been assembled by the means hereinafter described.
The said blades Gare carried by the arms G¹ of rock-shafts G2 which are arranged in
bearings on the framing. The said rock-shafts derive their necessary movements, for
operating the blades, from two similar cams G³ on a shaft P which is arranged in fixed
bearings on the framing A and which is driven from the shaft B at the rate of one revo-
lution of P to two of B through gears B and P¹ on the respective shafts. The con-
nections between the cams G3 and the rock-shafts G consist, as shown in Figure 2,
of yoke rods G' engaging with the cams and connected with downwardly projecting
arms G on the rock-shafts. The said two cams G³ are set in opposite directions in
order that the folding blades may be operated alternately at regular intervals.
In order to provide for folding the successive series of four sheets by the first and
second sets of folding devices alternately, the grippers c c¹ of the endless carrier
have to be so organized in alternate series of consecutive fours on each side that every
other series of fours will be opened to liberate their sheets as they arrive at the first
set of folding devices and the intervening alternate series must pass the first set with-
out opening and be opened as they arrive at the second set. The grippers are made
self-closing by means of springs as is cominon with such grippers and they are opened
by passing stationary cams f f on the frame C. The cams f, one on each side, for
opening the grippers c of the series which deliver to the first folding devices, are
arranged, as shown in the transverse sectional views Figures 7 and 8, so much higher
that the cams f for opening the grippers c¹ of the intervening series, that the short
rollers g attached to the grippers c¹ will pass under and clear of the said cams ƒ
although they will pass in operative contact with those f¹. The rollers of the
grippers are long enough to reach the higher cams f to open those grippers at
the proper place for the first folding devices."
For each folding apparatus or folding device there is a set of devices independent of
the carrier for assembling the sheets in fours on the folding plate H, a pair of folding
rollers L L for completing the folding commenced by the blade G, and a set of rotary
cutters N N for splitting the folded sheets across their folds into signatures. As the
two sets of these several devices are in most respects alike, it will be sufficient to
describe fully and in detail the first set, viz.: That which is nearest the cutters a b
and afterwards briefly describe the second set. The assembling devices in the first
set consist, as shown in Figures 1, 2 and 4, of a set of downwardly curved switch-
fingers h attached to a bar or rock-shaft I which is arranged crosswise of the carrier,
and feed rollers JK (see Figures 2 and 5) the said fingers h serving to direct the
forward edges of the sheets downwards towards the slotted folding plate H which, as
will be seen by reference to Figures, 1 and 2, has a forward and downward inclination,
and the said rollers J K serving to carry the sheets which have been liberated by the
earrier forwards and downwards on to the slotted table H. The roller J which is
under the carrier works in fixed bearings on the side framing A and derives rotary
motion from the shaft B with a surface velocity considerably less than that of the
carrier, through a horizontal shaft L arranged in bearings on the outside of the
framing A, and gearing which will be hereinafter described the said roller J making
one revolution while the carrier travels the length of a sheet. The roller J may be
and is represented as a full cylinder but K, which is merely a pressure roller, acting to
confine the paper to the roller J, is made up of a series of narrow-edged disks so
arranged as to press upon the sheets between the unprinted portions and hold them
to the roller J. The two outermost of said discs K are arranged to take the sheets
close to their side edges. All of said discs are notched as shown at 20, at opposite
points in their circumference. One object of these notches 20 is to allow the front

page_text: edges of the sheets to get directly between the centres of the rollers before the rollers
begin to take their hold upon the sheets but the notches in the two outermost discs
allow the carrier grippers to pass by those dises without interference as the grippers
will enter those notches. The said rollers K are geared with J to rotate at the same:
surface velocity by gears j¹ and 2 (see Figure 6).

The folding plate H has along its lower edge a stop gauge d (see Figures 2 and 5)
to which the sheets drop one at a time from the assembling rollers J K, so that all
those of a series of four are assembled evenly in a pile in proper position for folding
them all together midway between the cut edges as indicated by the dotted
Hines n n in Figures 12 and 13. In front of and above the folding plate H there are 1
arranged across the said plate two stationary horizontal shafts or bars m m to which
are attached fingers m¹ m² which guide the sheets in their way over the said
plate and confine them loosely thereto. Under and behind and parallel with the
folding plate H, opposite the slot k, therein are the pair of folding rollers L L which
work in suitable bearings on the side framing and which receive the several sheets
from the blade G and complete the folding commenced by the said blade in forcing
them through the slot. Behind and in rear of and parallel with the folding
rollers LL there are arranged the two parallel shafts M M on which are the three
pairs of rotary slitting cutters N N to which the folded sheets are carried by the
rollers 1 L to be slit transversely to their folds as indicated by the lines o o in
Figures, 12 and 13 to produce from each folded sheet a signature of sixteen pages
composed of four separate folded sheets of four pages each. The slitting cutters N
äre simply disc shear blades of well known kind.
The horizontal shaft L herein before mentioned drives not only the feed roller J.
but the folding rollers L L and the cutter shafts M M. The said shaft L* derives
motion from the shaft B through bevel gears i ix (see Figures 3 and 5) and it carries
another bevel gear; which gears with a bevel gear on one of the cutter shafts M M
(see Figures 1 and 6). The latter shafts are geared together by spur gears pp; and
the folding rollers are geared together by gears 9 9 (see Figures 1 and 6). One
of the gears pp and one of the gears qq are geared through an idler gear pivoted
to the framing, with a gear jix on the feed roller J, the said gearing / jx j¹, P P, q q
and thus driving the feed roller J, the folding rollers L L and the slitting
cutters N N. It may be here mentioned that the folding rollers L I have their sur-
faces knurled, as shown in the perspective view Figure 9, of one of said rollers, at
15 and 16 where they come in contact with the margins of the sheets and at 17
where they seize the folded edges thereof and between the said knurled portions
their surfaces are slightly depressed, as indicated at 18.
Except as to the guiding fingers h m² m² and the pressure roller K, the second
set of assembling, folding and slitting devices, vis: the set furthest from the
cutters ab, are similar in detail to the first set and they will be identified by the
similar letters of reference applied to their corresponding parts. In the first set
-the finger h and the pressure roller K have to be raised to allow the passage under
them of the alternating series of four sheets which are still held by the grippers cl
to be carried to the second folding plate H. The raising of the fingers h is effected
by rocking the said bar or shaft I in its fixed bearings on the framing, and provision
is made for raising the pressure roller K by mounting its shaft K¹ in bearings in the
arms K2 of a rock shaft K3 (see Figures 2 and 4) which is supported in fixed bearings
in the framing and by giving the said rock-shaft a suitable movement. In the
'second set the fingers h are dispensed with by giving an upward and backward
curved prolongation to the guide fingers m², as shown in Figure 2, and the shaft K¹
of the pressure roller is simply mounted in journal boxes e² to which springs are
applied in the manner cominon to pressure rollers.
The moveinent of the rock-shaft I for raising the fingers hand afterwards bringing
them down to the operative position and the movement of the rock shaft K³ for
raising and lowering the pressure roller K are both produced by means of two
similar cams I* on the shaft P hereinbefore described, the said cams I* operating

page_text: respectively as shown in Figures 3, 4 and 5, through rods K and I¹ connected with
arms K and I2 on the rock-shafts K³ and I.
:
In the operation herein before described of carrying the sheets by the grippers to
the assembling and folding apparatus the sheets are always held near their front
edges, leaving the rear edge of the following sheets to pass over it, but to prevent
the rear edges from thus dropping too low, there is arranged between the cutter
heads E F and the first assembling rollers J K, a sheet support consisting of a.
stationary transverse bar d¹ and a series of attached horizontal fingers d², and there
is also arranged between the first and second assembling rollers J K a similar set of
fingers d³ attached to the cross bar m which carries the guides m¹ for guiding the
sheets over the first folding plate.
Under the folding, assembling and slitting devices above described there is arranged
an intermittently traveling delivery carrier consisting principally of two parallel end-
less chains Q and a series of pockets QQ attached thereto for receiving the signa-
tures from the slitting cutters N and delivering them to a suitable receptacle but
before describing this receiving and delivering apparatus we will give a brief résumé
of the successive operations of the previously described parts from the reception of
the web by the gripper c c of the carrier to the slitting of the folded sheets by the
cutters N, first mentioning that the opening of the grippers to receive the web is
effected in a manner common to web and sheet carriers of this kind by passing a
stationary cain (see Figures 2 and 4) fast upon the fixed studs e on which rotate
the carrier wheels D₁ at the receiving end of the carrier.
The printed web taken by the grippers c is first cut into the short sheets S (see
Figures 12 and 13) which continue to be held by the grippers near their front edges
until the grippers successively arrive at and are opened by their respective cams ff¹.
Four consecutive sheets, held by the grippers c with the long rollers g and intended
to be released by the cams f for the first set of assembling, folding and slitting
devices, are released one at a time as their front edges arrive at the first feeding
rollers J K. When the first of these sheets has reached the said rollers and has
been released, it is fed by the said rollers onward down the folding plate H being
conducted under the sheet guides m¹ m² by the switch fingers . The feed rollers
feed the sheet at a slower speed than that at which the carrier travels and the second
sheet, still held by the grippers, is lapped over the first sheet a short distance when
it (the second sheet) is seized by the feeding rollers and for a short distance the two
sheets are fed along together before the first runs out from the feeding rollers and
drops to the stop gauge d. The distance which the sheet drops is less than the lap
of the two sheets so that the holding edge of the second will not catch on the rear
edge of the first sheet. In the same way the third sheet is lapped over the second
and the fourth over the third. When the fourth sheet has been guided part of the
way down the folding plate H, the switch fingers h and also the feeding rollers K of
the first set are lifted to allow the sheets intended for the second set of assembling,
folding and slitting devices to pass. When the four sheets on the first folding
plate I have all reached the gauge d and have been assembled in a pile thereon, the
folding blade G pushes the middle of the pile of sheets through the slot in the fold-
ing plate into the folding rollers L, the knurled surfaces of which seize it, pinch the
sheets together and pass them on to the slitting rollers by which each is cut into
'four signatures which are dropped into one of the delivery pockets Q which is for
the time stationary underneath them. In the meantime the four sheets carried by
the grippers c¹ with short rollers g¹, have been fed to the second set of assem-
bling, folding and slitting devices wherein the same operation is repeated, the
signatures being delivered into a delivery pocket Q which is at the time stationary
underneath.
The delivery pockets Q of the delivery carrier are represented of skeleton form
each consisting of a row of angle pieces carried by a bar Q2 the ends of which have
attached to them roller carriages Q3 (see Figure 10) which runs on tracks w (see
Figures 2 and 6) formed on two stationary side plates Q which are supported by

page_text: brackets Q (see Figure 6) on the main framing A. The said carriages are connected
with the two parallel endless chains Q hereinbefore mentioned which run on carrying
wheels R and R¹ on two horizontal shafts T and T fitted to bearings on the side
plates Q. The carriages Q3 may be attached to the chains Q¹ in any suitable
manner. They are represented in Figure 10 as screwed thereto by the pins x x
which connect the links of the chains Q together.
The shaft T is the driving shaft by which the delivery carrier has imparted to it
the necessary intermittent movement for presenting the pockets successively at the
proper time under the slitting cutters. This shaft T derives its movement from a
cam U on the shaft P, the said cam acting on a lever Ux (see Figures 4 and 11)
which works on a fulcrum pin t in a fixed standard t¹ and which carries a rack bar U2
which gears with a spur gear U¹ on the chain-driving shaft T: This spur gear is
loose on the said shaft T but it has attached to its hub a pawl u engaging with a
two-toothed ratchet wheel u which is fast on the said shaft and hence when the
lever moves away from the said shaft and towards the cam shaft P, the rack bar turns
the gear Us without turning the shaft but when the lever and rack bar are moved by
the cam away from the cam shaft, the ratchet wheel and the shaft T are turned
to the extent of a half revolution which is sufficient to give the chains and pockets a
movement equal to the distance between one pocket and the next. The lever U* is
constantly pressed towards its cam by a spring ux which works upon a rod u³ con-
nected with the said lever, the said spring abutting between a shoulder on the said
rod and a fixed bearing us, but, until the proper time arrives for moving the pockets,
the lever is locked out of the operative range of the cam by a hooked catch u³ which
is pivoted to the standard t¹ and which engages as shown in Figure 11, with a catch
piece u² on one side of the lever. When the proper time arrives the said catch u³ is
lifted from the catch piece and the lever is left to the action of the spring which
causes it to follow the cam so that it may be caused to move the chains and as the
rising portions of the latter comes into action on it.
The lifting of the catch ³ is effected as shown in Figure 4 by a movable tripping
tappet v on a spur gear V which turns on the pin t, the said tappet acting on a tripping
arm u attached to the catch u³, through a short trip lever t² (see Figures 3, 4, 4*)
which works on a fulcrum pin t3 on the standard . The said gear V is driven
by a gear W having a smaller number of teeth on the cam shaft. The said gear W has
fixedly attached to it a tappet lug v¹ which once during a certain number of
revolutions of the cam shaft comes into contact with the outer end of the movable
tappet vand pushes the latter inwards far enough for its inner end to act on the
lever and produces the disengagement of the lever U which is then pushed back
by the spring u* as shown in Figure 4, into operative contact with the lower portion
of the cam. The tappet has applied to it a spring v which presses it outwards to
the position to be met by the tappet v¹ but which allows it to move inward to act
on the lever v².
=
The number of teeth on the gears V and W and the number of tappets on the
gear V will depend upon the number of signatures to be deposited in each pocket.
Suppose for example that the gear W has thirty five teeth and V thirty six and V
is provided with two tappets v. The cam shaft P making one revolution to two
assemblages of four sheets S folded, that is to say, to one assemblage of sheets
folded by each folder, the tappet gear V will make. eighteen (36÷2 18)
revolutions between the times of moving the receiving pockets, and as both
folders deliver into the same pockets, each will contain thirty six folded and slit
sheets or one hundred and forty four signatures when it reaches the delivery
point at the outer end of the machine, eighteen sheets or seventy two signatures
having been delivered into it from the first folding and slitting apparatus and
eighteen from the second.
Suppose again that with the same number of teeth on the gears W V there
should be three tappets on the gear V, then the said gear will make twelve
(36312) revolutions between the times of moving the receiving pockets
and each pocket will contain twenty four sheets or ninety six signatures.
