Improvements relating to Folding and Delivery Mechanism for
Printing Machines.
I, HENRY EDWARD NEWTON, of the Office for Patents, 6, Breams 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 this invention is the making of a folded product consisting of
a sheet whose sides are each infolded twice in opposite directions onto the same
side of its body, preferably, but not necessarily equally, and pre-
ferably, but not essentially, having the inversely folded parts more
Ol'
less overlapped; and in a modified form, such a sheet with the
described side folds omitted. The invention includes, first, a mechanism con-
sisting of two sets of coacting folding instrumentalities, whereby two transverse
folds are imparted to a sheet and a cutting mechanism in such relation thereto,
that a web is severed transversely, and has its front and rear ends lapped inwardly
or toward each other on the same side of its body; second, in combination there-
with a longitudinal folder, whereby the sides of said sheet are primarily infolded
upon its body; third, in combination with either of the foregoing, a rotary
printing mechanism with the form-bearing portions of its form-cylinders so
related to the rotative folding mechanism as to correctly imprint the said sheets;
and fourth, in combination with the rotative folding mechanism, of a pasting
mechanism whereby the folded laps may be secured together.
The invention also includes certain improvements in the sheet-impaling pins.
which are preferably used to take the leading end of the product, and forward
it through the cutting and folding rolls.
This invention is hereinafter particularly described, aided by one embodi-
ment of it, illustrated by the accompanying drawings in which:-

It is to be understood that this delivery apparatus is adapted to form a part
of any type of printing machine whereby a web is perfected. For the better
elucidation of the present improvements, they are shewn, in Figure 1, as com-
bined with a web printing machine of that type known as a double-ender, in
which the web W, led from a roll, is guided over rollers 110, 120, and passed
between the type cylinder T and impression cylinder I at one end thereof, and,
thus printed upon one side, is led over a roller 130 and around a V-shaped
transferrer and reverser; thence again between the type and impression cylinders,
but at the other end thereof, whereby it is perfected by being printed on its
second side. To prevent offset upon the impression cylinder from the first
printed side of this web, it is accompanied in its second passage through the
printing couple by an offset web 0. This perfected web, marked W, is shown
as entering into this delivery apparatus by passing over a roller 76, which is
surmounted by a slitting disc 20, whereby said web is divided longitudinally
into two webs. This delivery apparatus embodies a pair of longitudinal
folders A, B, the structure of which is more particularly hereinafter described,
a rotary folding and cutting mechanism the devices of which are carried respec-
tively by cylinders D, E, F, and a sheet-laying device consisting of a rotary
fly, said cylinders D, E, F, being of double length so as to operate upon half
webs, into which the main web is divided by the slitter 20, and the rotary flies
and other parts are duplicated, where necessary to act upon the two products
that are formed side by side in the machine.
This delivery mechanism is driven at proper speed by means of a vertical
countershaft 30, which derives its motion through beveled gears from a longi-
tudinal shaft 31 that is driven from the printing machine. The shaft 40 of
the cylinder D is driven from said shaft 30 by means of beveled gears 41, 42,
and on the opposite end of said shaft 40 is carried, outside of the frame, a
wheel 43 which drives a pinion 44 on the shaft 50 of the cylinder E, and this
pinion 44 gears with a pinion 45 on the shaft 51 of the cylinder F. The
shaft 51 also carries within the side frame a wheel 52, which meshes with an
intermediate wheel 53 on a shaft 54, that carries, further, within the side frame,
a pinion 55, which meshes with a wheel 56 on the fly shaft 57.
The shaft 50 also carries, near to the pinion 44, a pinion 46, which drives a
pinion 47 on the paster shaft 48, and this shaft 48, through pinions 58, 59,
and wheels 60, 61, revolves the paste fountain discs. The shaft 40 of cylinder D
carries within the side frame a wheel 64, which, through an intermediate 65,
drives the pressing rollers 80, 90, which are geared together by intermeshing
pinions 68, 69, the pinion 68 gearing with the pinion 65. This wheel 64 also
drives the web roller 76 through a train of gears 70, 71, 72, 73, 74, and 75.

page_text: The cylinder F carries at one end a wheel 77, which, through a pinion 78, drives
the pressing roller 29 and the delivery rollers 33, 34 are geared together.
by pinions, only one of which, 79, is shown, and these rollers are driven by
means of a pinion 81 on the shaft of roller 33 that gears with the inter-
mediate 82 from the wheel 77.
The longitudinal folders A, B, in a general sense, are of a well-known type.
Each consists of a horizontal plate which is formed to provide three internal
guides, 35, 36, and 37. The guide 35 is formed by the formost edge of the
plate, and is of a length equal to the width of that of the ultimately longitu-
dinally-folded product, and the guides 36 37 extend rearwardly from the ends
of the guide 35 respectively at angles diverging to the rear edge of the plate,
where it is of a width equal to that of the outspread or unfolded web. Of
course these internal guides might be formed by bars, but the plate structure
is preferable. The external turners consists of guides 27, 28, that are inclined
obliquely downwardly and forwardly from the internal guide 35, and, though
closely superposed, they are relatively arranged across each other at acute
angles in the path of the two sides of the web, so that they operate to lap the
sides of the web that project outwardly beyond the ends of the guide 35 suc-
cessively inward over the central portion of the web, and so that the sides
thereof are infolded, and preferably so that one side overlaps the other side, and
preferably so as to form three plies of equal extent.
These guides, as illustrated, are preferably the inner edges of plates obliquely
arranged with respect to the plate forming the internal guides, but might of
course be bars, if desired. The plate structure for both the internal and
external guides is preferred, because it affords an easy means for securing the
same in position. The co-operation of the three internal guides and the two
external guides results in folding the web upon two longitudinal lines defined
at the ends of the guides 35,-the guide 27 turning one side inwardly, and the
guide 28 turning the opposite side inwardly, thus lapping the web on two parallel
lines inwardly, the two sides being lapped in succession one onto the other in
three plies, as is seen in Figure 4, where the folded web W is shown as broken
away.
It may now be remarked that the arrangement of these five guides, consti-
tuting the folder, may be such as to lap the outer portions of the web upon one
another to a lesser extent than a folder which will produce three equal laps, as
shown, and this lateral lapping of the sides may be in such a relation to the
central part of the web, as to cause the side laps simply to meet, and thus form
two plies, or, if desired, it may leave their edges nearly together, but not in
contact, according as is preferred.
The longitudinally folded web thus produced has its folds laid in passing
between the rollers 80, 90, preferably spring-seated which act as fold laying
or pressing rollers, and as feeding rollers. These rollers are geared together by
toothed wheels 68. 69, and driven by an intermediate 65 from the toothed
wheel 64 on the shaft of the cylinder D. Only one longitudinal folder has
been described, but it may be remarked that two folders precisely alike are
provided, so as to operate upon two narrow webs, and that a wide web W
received from the printing machine is fed over a roller 76, and slit into two
webs by means of the disc slitter 20 that co-operates with said roller for that
purpose. These two webs are then passed to the longitudinal folders A and B,
and are each respectively of a width equal to the rear edges of these folders.
Each double longitudinally-folded and lapped web passes from the longitudinal
folders to and between the cylinders D. E.
The cylinders D, E, F, and their accessories, constitute a rotating cutting
and folding apparatus provided with mechanisms that capacitate it to cut a
web transversely into lengths, and to fold the same transversely in such manner
as to lay the folds toward each other, and it may and preferably will be one
upon the other, thus producing a three-ply product. The cylinder D is pre-

page_text: ferably circumferentially twice the length of the unfolded product to be pro-
duced. and is provided with cutting blades 10, 11, mounted at opposite points.
in said cylinder, and rearwardly of each of these blades there are provided
sheet-impaling pins 2, 3. The pins project through tangentially arranged
guide-ways 21. 31, in the body of the cylinder D, and they are respectively
pivoted to rock arms 221, that are fast to rock shafts 22, 23, which are spring-
seated, so as to normally hold the pins protruded from the cylinder (see
Figure 12), and suitably rocked to withdraw said pins by means of rock
arms 16, 26, that contact with a cam 96, that is held stationary by means of a
bracket 97 fixed to the side frame (see Fig. 3).
It sometimes occurs in mechanism for handling webs, that there is a slight
variation between the speed of the web or sheet which is to be taken by the
pins, and the speed of the pins. This variation may be due either to the fact
that the web or sheet travels a trifle slower than the surface speed of the
cylinder which carries the pins, or to the fact that when the pins are protruded
beyond the surface of the cylinder, they have a slightly greater circumferential
distance to travel than the surface of the cylinder, and consequently travel
somewhat faster than the cylinder. The difference in speed between the travel
of the webs or sheets and that of the pins, whether it be due to the causes
mentioned, or to other causes, results in a slight tearing or slitting of the webs
or sheets at the points where the pins are inserted. These slits or tears, while
not of great extent, are sufficient to disfigure the material.
The connection between the pin 2 and the studs on the rock arm 221 is a
loose connection which permits of a slight axial movement of the pins with
relation to the studs, and the guideways 21, 31 are enlarged to permit this move-
ment, as is clearly shewn in Figures 20 and 21.
The cylinder is also provided with a series of perforations 130. Located in
these perforations are headed pins 140, the stems of said pins being surrounded
by light springs 150, which bear against the heads of the pins at one end, and
against the screw plugs 160 at the other end. The screw plugs engage screw
threads in the perforations 130, and serve to adjust the tension of the springs,
as well as to afford a bearing surface for them. The springs and plugs serve
to back up the paper-taking pins, and the axial movement which has been
referred to as occurring between the shanks of the pins and the studs of the
arms by which they are operated, takes place against the stress of the springs.
It may be here remarked that, while the plugs are preferably used in connec-
tion with the springs, they may, if desired, be omitted, and the springs be
used alone.
Figure 20 shows the pins in the position which they occupy at the instant
when they have protruded by the movement of the rod which carries them,
and have passed through the web or sheet, the leading end of which they are
to take. At this time, the pins are forced by the springs and plugs against
the further side of the guideways 21 in the cylinder through which said pins
pass. If the web or sheet and the surface of the cylinder are travelling at the
same speed, there will be no movement of the pins other than that by which
they are caused to impale the material. If, however, the pins are, for any
reason, travelling slightly faster than the material the springs will allow
them to turn slightly with relation to the studs on which they are mounted, and
permit them to assume the position shewn in Figure 21, thereby preventing
them from tearing the material, since, by the time the pins have been moved
to the other side of the guideways 21, the speed of the pins and material will
have become equalized.
It will be understood that the springs 150 will be light springs, their strength
and tension being however controlled by the weight of the web of material
which the pins are to impale.
This cylinder D is also provided with tucking blades 4, 5, which are situated
diametrically opposite one another, and circumferentially one-third the distance

page_text: between the cutting blades 10, 11, in the direction in which the said cylinder
travels, and these tucking blades are so secured in sockets in the cylinder D,
and seated upon springs therein, as to be capable of slight circumferential play,
whereby the changing angular relation of their edges with relation to the
nipping jaws 7, carried on the folding cylinder E, prevents their acting as cut-
ting devices upon the fold of the paper, which might result from the shearing
action which they would otherwise have. The springs are located on the rear
side of the tucking blade, the front side of the blade being considered as that
side which is first presented to the nipping jaws, as the cylinder rotates. This
location of the springs enables the blade to have a circumferential movement
or play, as the blade enters between the nipping jaws. It is essential, in order
to avoid the shearing action which it is desired to avoid, that the springs be
located on this side of the blade. This cylinder D may, if desired, be pro-
vided with a conductor 99, arranged near its surface, for the guidance of the
sheet when detached from the holding pins. The cylinder E is equal circum-
ferentially to the length of the unfolded product, being of half the size of the
cylinder D. This cylinder E is provided with a cutting slot 6 formed in a box,
as is common, which cutting slot 6 co-operates with the cutting blades 10, 11,
that have clastic side pieces to hold the paper while being, cut, as is usual.
The first folding mechanism or folding device, properly so called, to act
upon the sheet, and by which the first fold therein is produced, is the cylinder E.
This cylinder is provided with a fixed nipping jaw 7, and a movable nipping
jaw 8. The movable jaw 8 is mounted upon a rock shaft 32, and normally is
held closed by means of a spring rod 84, attached to its rock arm 25. This
shaft 32 is suitably rocked at timely intervals by means of a cam 63 (Figures 4.
to 12), with which the roll of the rock arm contacts, to open said jaw. When the
jaw 8 is open, the paper is suitably presented to the folding cylinder E, by being
tucked between the jaws 7 and 8 by the tucking blades 4 and 5 on the cylinder D.
When the paper has been tucked between the jaws, the conformation of the
cam 63 allows the movable jaw S to be closed by its spring rod. The paper is
then seized, & firmly held by the jaws, & being now under the control of
the folding cylinder, is carried onward thereby, & the first fold is formed.
After the fold is formed, the cam 63 again operates the movable jaw 8, to
release the folded paper. This folding cylinder is also provided with a tucking
blade 12, that reciprocates in a guiding recess formed through the block in
which the cutting slot 6 is formed, & has such a range of movement as to clear
said slot, & thus permit the proper performance of the cutting action, & yet be
protruded beyond the surface of the cylinder E, for performing its tucking
operations.
•
For reciprocating this tucking blade 12, which normally is held inwardly by
means of a spring rod 93, it is provided with a rack 9, that co-operates with
a segment 13 projecting from a shaft 14, suitably rocked by a rock arm 38
contacting with a fixed cam 39.
This cylinder is furthermore provided with a paste-receiving and applying
arm 15, that projects from a rock shaft St, that has a rock arm 87, which is
actuated by a fixed cam 24 which encircles the shaft of the carrier E. The
paste applying arm 15 is normally held within the cylinder E, and somewhat
within its periphery, by means of the spring 85, attached to the shaft 86, and
acting to so rotate the shaft as to accomplish this purpose. Its actuating cam 24
is so shaped that it projects the arm 15 flush with the periphery of the cylinder
at suitable times, that it may receive a film of paste thereon, and be then
withdrawn within the cylinder E, and again be protruded therefrom at the
proper time to apply the paste it carries in a spot upon the folded product, as
will be hereinafter explained.
For co-operation with this paste arm 15 in the cylinder E, and for the purpose
of providing the material for such spot. that is to be deposited upon the pro-
duct, there is arranged in proper co-operative position a rotating paster P, the

page_text: single projecting part, 1, of which moves in a circular path, that enables it to
contact with and deposit paste upon the paste arm 15, which latter operates to
transfer the paste in a spot on the partially folded product. This paster P
receives its charge of paste by contact with a fountain disc 62 that rotates in a
paste fountain 100.
After the first fold has been formed in the paper by the folding mechanism
herein before described, and the paste has been applied thereto by the pasting
devices, the paper passes to the control of the second folding mechanism, pro-
perly so called, which is the cylinder F. This cylinder F is provided with a
fixed nipping jaw 17 and a movable jaw 18, projecting from a shaft 83, which
carries outside the cylinder a cross-head 19, that has one end attached to a
spring rod 21, whereby the said jaw 18 is normally held closed, and which
cross-head has a stud or bowl contacting with a cami 98, whereby said jaw is
operated at proper times. Co-operating with this cylinder F for laying the
plies of the folded product together, after the fold has been made, is the spring-
seated pressing-roller 29, and beneath this cylinder F and roller 29 are situated
the delivery rollers 33, 34, which receive the folded sheet, and convey it,
guided by the conductors 94, into the recesses a, b, of the rotary fly X, and
into fixed and facing vertically slots e of the guide 49 (see Figure 3). The
recesses ab are cut into the rotary fly in such a manner that they leave, pro-
jecting outwardly from them, arms of such width as to form propellers acting
to thrust the sheet forward from out of the slots e of the guides 49, into the
packing chute 92.
The web of paper led from a printing mechanism or other source of supply,
passes under the slitter 20, where it is divided into two half webs, which
respectively pass over the longitudinal folders A and B, where each receives a
double longitudinal fold, as herein before described.
It will of course be understood that two half width webs may be fed to the
folding mechanism before described, in which case the slitting devices will be
omitted. It is also to be understood that sheets of the proper length may be
fed to the folding devices, instead of webs, should this be thought desirable.
As the manipulation of both webs is the same, a description of the operation
in connection with but one, will now be given. The double longitudinally
folded web passes from between the pressing and fold laying rollers 80, 90,
down to and between the cylinders D, E. Its leading end is caught upon the
pins, say 3, the pins yielding slightly, as before described, to equalize any
difference in speed between them and the web, and by it the web is carried
around upon the surface of the cylinder D, for preferably two-thirds of the
length of the product to be made, when the forward end is released by the cam
operating said pin 3, to withdraw it. Simultaneously, or about simultaneously
therewith, the tucking blade 5 will have pressed the body of the web on a trans-
verse line toward the cylinder E, and tucked the same within the nip of the
spring-seated jaw 8 and its fixed companion 7, as in Figure 6.
The cylinders D, E, continuing to revolve, the web nipped by the jaws 7, 8.
will then follow the periphery of the cylinder E, as in Figure 7, and the first
fold will be formed. When these cylinders have revolved far enough to bring
the cutting blade 10 and cutting slot 6 into coaction, as in Figure 7, which
will, in the illustrated case, be at a point rearward of the first fold, a distance
preferably equal to one-third the length of the unfolded product, the web will
be severed transversely thereby, and the newly formed end of the web will be
impaled by the pin 2, and the new leading end of the web thus held will follow
When the cylinder E has
the periphery of the cylinder D, as in Figure 9.
revolved far enough to lay the forward or first folded part of the web upon and
next to its surface, as in Figure 8, the paste arm 15 will be in its outward
position, so as to contact with it and deposit its paste in a spot upon the folded
lap near to its line of fold, and about equidistant from its sides. This move-

page_text: ment of the cylinder will have brought the free rearward portion of the now
partly-folded product or sheet to that point where the next fold is to be made.
The tucking blade 12 will now be projected from the folding cylinder E, and
will operate to present the product or sheet to the folding cylinder F, tucking it
between the jaws 18, 17, thereof. This tucking is preferably made on a transverse
line, which is distant from the now rearward edge of the sheet by one-third the
length of the unfolded sheet or product. Simultaneously with the tucking
operation, the jaws 7, 8, of the folding cylinder E release their hold upon the
first fold of the sheet, thus leaving the sheet entirely under the control of the
folding cylinder F. As the folding cylinder F revolves, a second fold will be
formed, after which the folded sheet is presented to the pressing or laying
roller 29, and both folds are acted upon thereby. After the edge of the sheet
has passed between the cylinder F and the roller 29, the jaws 18, 17, will be
released, but the sheet will of course continue its movement, and the last ply
being pressed upon the first one, upon which paste has been previously deposited,
as before described, a three-ply product is formed, having its front and rear
ends laid toward and upon each other, and then pasted together. The folded
and pasted product, guided by the conductors 94, 95, and descending between
the cylinder F and roller 29, by which it is propelled, as in Figure 5, will be
directed by the conductors 94, 95, into the nip of the delivery rollers 33, 34,
as in Figure 10. These rollers will deliver the folded product into the guides e;
which direct it to the rotary fly, where it will momentarily rest vertically upon
the bottom board of the packing shute or box 92, and thereafter will be forced
in a forward direction into the packing box by the cam action of the next rear-
ward arm of the fly X, which presses it onward until its sides elastically pass
the front edges of guides c of the packing box, where it rests undisturbed until
it is displaced and moved still further outward by the arrival of the next
product.
In this operation it will be understood that when the leading end of the
web has been fed for two-thirds of a sheet's length, it has been tucked and
nipped for the first fold, and when the remaining one-third sheet's length
follows, that the web is severed on the proper cutting line at the same point
where the said first fold was made. Then, while the cylinder E is making a
further quarter turn, the folding blade 12 is moved outward through the
inwardly extended cutting slot, and coacts with the nipping jaws of the
cylinder F, and stands projected from the periphery of the said cylinder in
proper position so as to make the last fold in the sheet, and is thereafter with-
drawn into said slot for the incoming web in the severance of another sheet
therefrom. Also, that when the forward end of a succeeding sheet's length is
caught by the pin 2, and is following the course of the preceding one, the
cylinder will be carrying the first once-folded sheet onward to receive its
second cross or transverse fold. Also, that while the cylinder E is making its
revolution, and the pasting arm 15 is approaching the point where the paster P
revolves, the cam 24 will cause said arm 15 to stand in its forward position, 80
as to receive paste from the paster 1', and that as soon as this is accomplished,
said arm 15 will be withdrawn within the cylinder face, and there remain until
an appropriate time has arrived, such as when the second cross folding action
is taking place, when it will again be protruded in such a position as to apply
the spot of paste in the manner described, so that when the second cross-fold is
completed, the otherwise free cross-folded laps of the folded product will be
fastened together lightly, just within the outer edge of the second cross lap.
This pasting may of course be omitted. As here arranged to operate, it will be
observed that the actuating cam 24 is so shaped that the pasting arm is pro-
jected outward to receive its paste, it is then withdrawn and held within the
carrier until the tucking has been effected; is then projected far enough to
make effective contact with the folded sheet in depositing the spot of paste

page_text: thereon; is then withdrawn to so pass the carrier F as not to injure the paper
or itself; and then is projected to receive its charge of paste. The carriers
D, E, F, may all be one size, and arranged in a straight line.
While the cutting means may be located between the printing machine and
any folding mechanism, or between the longitudinal and rotating folding
mechanism, and must be so arranged that the first transverse folding shall be
upon the rearward portion of the sheet, it is preferable to provide it in the
first pair of folding blade-carriers, substantially as herein illustrated.
It will be perceived that since the pasting requisite in the production of this
product is only a small spot, that the pasting appliance may be arranged to
deposit a spot of paste upon the web at a proper point before it enters the fold-
ing mechanism, and that a recess in the carrier E may then be provided, so
that the paste shall not offset thereon, which recess, in the case where the
carrier E also carries the cutting slot, may be in the forward portion of the
cutting box in which said slot is formed. Also, that other means for accom-
plishing this pasting of the folded product together may be adopted, and still be
within this invention.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed (as communicated
to me from abroad), I declare that what I claim is:
1. In a folding mechanism, the combination with devices for folding a sheet,
so that its two parts shall be of unequal length, of a second set of devices for
giving the sheet a fold in a direction opposite to that in which the first fold
was made, the corresponding members of each set of folding devices being
mounted independently of each other, substantially as described.

mounted independently of each other, and means for applying paste to one of
the folds, substantially as described.
3. In a folding mechanism the combination with devices for folding a sheet

operating to tuck a sheet between the jaws on a line unequally distant from the
ends of the sheet, and the carrier operating to fold the sheet; a- tucking blade
on the second carrier; a third carrier provided with nipping jaws, the said
blade acting to tuck the partially folded sheet into said jaws, and the third
carrier operating to give it a fold in a direction opposite to that given it by
the second carrier; and a cutting mechanism, substantially as described.
12. The combination with a rotary printing machine of a rotating carrier
provided with a tucking blade; a second carrier provided with nipping jaws,
the blade operating to tuck a sheet between the jaws on a line unequally distant
from the ends of the sheet, and the carrier operating to fold the sheet; a tuck-
ing blade on the second carrier; a third carrier provided with nipping jaws,
the said blade acting to tuck the partially folded sheet into said jaws, and the
third carrier operating to give it a fold in a direction opposite to that given
it by the second carrier; and a cutting mechanism, substantially as described.
13. The combination with a rotative carrier provided with a tucking blade;
a cooperating rotative carrier provided with nipping jaws, and a tucking blade;
and a third rotative carrier provided with nipping jaws cooperating with the last-
named tucking blade, of a pasting mechanism consisting of a pasting arm 15, and
means for vibrating it within the carrier E, and operating to deposit paste upon
the sheet, whereby each sheet length is folded twice transversely, its front and
rear portions are lapped toward each other upon the same side of its body, and
the outermost lap is secured, near its cut end, to the first folded lap, substan-
tially as described.
14. In a combined folding and cutting mechanism, the combination with
the slotted cutting box, of a tucking or folding blade operating through the
same, and provided with means to expose the outward part of the slot for the
cutting operation, and to protrude the blade through the same for the tucking
or folding operation, substantially as described.

formed by a tucking blade and nipping jaws, the combination with said blade,
of springs located in the rear of the blade, whereby said blade may slightly
move rearward circumferentially, as it meets said jaws, substantially as
described.
16. In a rotating cutting and folding mechanism the combination of three
carriers; cutting devices, the cooperating members of which are located upon
two of the carriers; tucking blades located upon two of the carriers, and nip-
ping jaws located upon two of the carriers, the tucking blade of one of the
carriers operating through the cutting slot thereof, substantially as described.
17. The combination with a carrier, of impaling devices mounted thereon,
said devices being arranged to have a limited movement in a direction opposite
to the movement of the carrier, which movement is insufficient to release a
sheet or web taken by the impaling devices, whereby a sheet or web may be
taken by the impaling devices, and forwarded thereby without being torn, sub-
stantially as described.
18. The combination with a rotating carrier, of impaling devices mounted
thereon, and operating means whereby said devices may be caused to take and
release a web or sheet, the connection between the operating means and the
impaling devices being such as to permit a limited movement of said devices
