Improvements in Web Printing and Folding Machines.
I, ROBERT CUMMING ANNAND, of Cornwallis Street, South Shields, in the County
of Durham, Printer's Engineer, do hereby declare the nature of this invention
to be as follows:-
My invention has reference to web printing and folding machines and com-
prises a particular arrangement and disposition of the printing cylinders and
inking mechanism in relation to one another in a web printing machine; also
an arrangement and design of the printing presses so that one two or three
more presses can be subsequently added to a single printing machine and folder
without necessitating any change in the construction of the printing mechanisms
first made; also an improved arrangement whereby copies of a newspaper
consisting of 10 or 12 pages can be produced from a printing machine using only
two rolls of paper, with all the leaves inset; and an arrangement whereby a
two-roll machine will produce copies of a 6, 8, 10, 12 or 16 page paper with all
the leaves inset; it also includes an improved mode and means of returning
the endless tapes which carry the cut sheets over the fold-former, and thereby
fold the sheets longitudinally.
It frequently happens that a newspaper proprietor who may at first only
purchase a machine capable of producing 4 and 8 page papers, finds after a
time that he must increase the size of his newspaper to, say 10 or 12 or 16 pages.
He finds that his machine cannot be economically converted to produce larger
sizes, and he is obliged to buy a larger one.
According to my invention I construct a single printing mechanism with the
printing parts so arranged and the frame-work so constructed that another
printing press can be mounted or set on above the original machine and be
worked in combination with it without costly adaptation. This would form a
two-roll machine, capable of printing up to 16 pages if a folder and delivery
mechanism were attached capable of dealing with the product. If a further
extension of the printing capacity of the machine is required, a third printing
mechanism can be added. I erect this third printing press in line with the
other two, with the cylinders parallel and the two delivery ends of the presses
facing one another, a space being left in the middle for the folding mechanism.
This third press is precisely the same in design as the first. The framework
is so arranged and faced that a fourth press can be added on the top of the same
design as the second press. The rolls of paper are all carried outside the machine,
and the webs when printed all leave the printing presses on the inside.
The folding apparatus is placed in the middle and may consist of single or
double longitudinal folders, such as those described in my Patent Specifications
Nos. 21068 of 1893 or No. 4011 of 1895 placed between two presses set end to
end. The longitudinal folders described in the said Specifications deal only with
the webs in their uncut state.
It is well-known that although the full capacity of, say, a four-roll press

page_text: is 32 pages, when the webs are folded longitudinally in their uncut state, it is
only possible to inset half that number of pages or four sheets of 4 pages each.
In order to obtain a 10, 12, or 16 page product from a two-roll printing press,
I arrange the folder so that the webs are cut into sheets before they are folded
longitudinally. For producing a 12 page product I arrange a pair of cutting
cylinders at the top of the fold-former. There is another pair of cutting cylinders
placed preferably underneath the last blanket and stereotype cylinders on the
top press. The top press is made in this case to run at half the speed that the
bottom one runs at. One of the cutting cylinders on the top of the fold-former
is made to collect the cut sheets by pins operated by cams, in the well-known
way. The web from the bottom press is led up to the cutting cylinders on the
top of the fold-former and cut into sheets, the pins collecting two sheets above
one another, forming together 8 pages or the full product of the bottom machine.
While two sheets are collected on the collecting cylinder, one sheet has been
partly cut off from the web printed in the top press, by the supplementary
cutting cylinders, and when its leading edge reaches a position above the main
cutting cylinders a breaking roller entirely separates the sheet from the web
and sends it forward at the same speed as the other sheets, which it is timed to.
join as they are being carried from the collecting cylinder by the conveyance
cylinder which now carries the three sheets into two sets of endless tapes which
draw them over the fold former and thus fold them longitudinally.
A 10 page product can be produced by the same means as a 12 page product
by using half a web in the top press instead of a whole one.
A less costly machine can be made to produce a 10 page product by construct-
ing the top press with only one stereotype cylinder, one blanket cylinder and one
set of inking mechanism instead of having these in duplicate as in the bottom
press. The half web is first printed on one side, it is then passed over angle or
turning bars, it again. passes through between the same printing cylinders at
the opposite end and is printed on the opposite side..
When it is desired to produce a 6, 8 or 16 page paper, the top press which
must have a capacity of printing 8 pages is made to run at the same speed as
the bottom. The cutting knife is taken out of the supplementary cutting
cylinders, and the top web is led along a different pathway to join the other
web, both passing through between the same pair of cutting cylinders and being
folded afterwards by the fold-former.
Instead of returning the top tapes that pass over the fold-former above the
sheets by means of a series of guide pulleys which take up room besides looking
complicated, I place a section of a tube cut longitudinally into three, or a similar
rounded piece of metal, a little above the converging edges of the fold-former
and parallel to its edges. The return tapes slide over these rounded pieces of
metal and are returned to their places on the conveyance cylinder. Flat strips
of metal may be placed at a suitable angle on these rounded sides to act as guides
for the tapes.
In a web printing machine it is alway's desirable that the web while it is pass-
ing over the second blanket cylinder and receiving the last impression, should
not be in contact with the blanket cylinder for any great distance.
In my particular arrangement of printing cylinders, I secure that while the
web is receiving the final impression it is only in contact with the blanket
cylinder for a small part of its circumference.
This obviates set-off and also saves strain on the paper and prevents breakages.
The manner in which this may be carried into effect in for example a two-
roll machine having a bottom printing mechanism and a top printing mechanism
is as follows:
The inking mechanism of the first side in the lower press is arranged practi-
cally in a vertical position with the stereotype cylinder at the top. The first
blanket cylinder is in the same horizontal plane as its co-acting stereotype
cylinder. A horizontal line passing through the axes of the first stereotype and

page_text: nrst blanket cylinders passes through the point of contact between the second
stereotype cylinder and the second blanket cylinder. The second inking mech-
anism slopes upward at an angle so as to allow the printed web to be carried
upwards to the top of the fold-former. The inking mechanism of the first side
in the top press and the corresponding stereotype blanket cylinders and the
second blanket cylinder are all practically in the same horizontal plane.
The second stereotype cylinder is placed above its blanket cylinder.
By the arrangement above described the web of paper has only a very short
dwell on the set off blanket cylinder in both top and bottom presses. The posi-
tion of the cylinders in relation to one another can be somewhat varied without
departing from the invention. When one or two other presses are combined
with the two above referred to they are similarly arranged as regards the rela-
tive positions of their stereotype and blanket cylinders and inking mechanism.

improvements in Web Printing and Folding Machines.
I, ROBERT CUMMING ANNAND, of Cornwallis Street, South Shields, in the County
of Durham, Printer's Engineer, 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:-
-
My invention has reference to web printing and folding machines and com-
prises an improved arrangement whereby copies of a newspaper consisting of
10 or 12 pages can be produced from a printing machine using only two rolls
of paper, with all the leaves inset; and an arrangement whereby a two-roll
machine will produce copies of a 6, 8, 10, 12 or 16 page paper with all the leaves
inset; it also includes an improved mode and means of returning the endless
tapes which carry the cut sheets over the fold-former, and thereby fold the
sheets longitudinally.
The arrangement of the various members of a machine constructed in accord-
ance with this invention is such that it occupies comparatively small space, is
simple and handy to look after and can be changed from producing one size to
another with little alteration, these alterations being so simple and safeguarded
that risk of damage in unskilled hands, through making the alterations is reduced
to a minimum. A feature of the invention is the position in which tlie various
parts of the combined machine stand in relation to one another.
ture is in the arrangement whereby the cut off sheets printed in the top press.
Another fea-
when running at half the speed of the bottom press, are associated in register
with the sheets printed in the bottom press.
Machines of this class as hitherto made have been so arranged that the cut
off sheet from the half speed mechanism joins the uncut web from the other:
press and both the cut sheet and the uncut web pass through between a pair of
cutting cylinders. Unless the cut off sheet is shorter (which is objectionable).
than the space between the cutting knives on the second pair of cutting cylinders
it has been found practically impossible to get such absolute register as to always
get the ends of the added sheets to come exactly where the cuts take place in
The main web. The result is that occasionally part of the cut sheets overlaps
he perforator and is partly cut off and these shavings or strips get about the

page_text: machine and are folded up with the papers giving them a ragged and unfinished
appearance. In my associating arrangement the mechanism is so constructed
that the cut sheet from the slow printing mechanism does not join the sheets
from the main press until after they are cut off from the web. This avoids any
risks of these objectionable shavings or strips of paper being sent out with the
papers.
In order to obtain a 10, 12, or 16 page product from a two-roll printing press,
I arrange the folder so that the webs are cut into sheets before they are folded
longitudinally. For producing a 12 page product I arrange a pair of cutting
cylinders at the top of the fold-former. There is another pair of cutting cylinders
placed preferably underneath the last blanket and stereotype cylinders on the
top press. The top press is made in this case to run at half the speed that the
bottom one runs at. One of the cutting cylinders on the top of the fold-former
is made to collect the cut sheets by pins operated by cams, in the well-known
way:
The web from the bottom press is led up to the cutting cylinders on the
top of the fold former and cut into sheets, the pins collecting two sheets above
one another, forming together 8 pages or the full product of the bottom machine.
While two sheets are collected on the collecting cylinder, one sheet has been
partly cut off from the web printed in the top press, by the supplementary
cutting cylinders, and when its leading edge reaches a position above the main
cutting cylinders a breaking roller entirely separates the sheet from the web
and sends it forward at the same speed as the other sheets, which it is timed to
join as they are being carried from the collecting cylinder by the conveyance
cylinder which now carries the three sheets into two sets of endless tapes which
draw them over the fold former and thus fold them longitudinally.
A 10 page product can be produced by the same means as a 12 page product
by using half a web in the top press instead of a whole one.
A less costly machine can be made to produce a 10 page product by construct-
ing the top press with only one stereotype cylinder, one blanket cylinder and one
set of inking mechanism instead of having these in duplicate as in the bottom
press. The half web is first printed on one side, it is then passed over angle or
turning bars, it again passes through between the same printing cylinders at
the opposite end and is printed on the opposite side.
When it is desired to produce a 6, 8 or 16 page paper, the top press which
must have a capacity of printing 8 pages is made to run at the same speed as
the bottom. The cutting knife is taken out of the supplementary cutting
cylinders, and the top web is led along a different pathway to join the other
web, both passing through between the same pair of cutting cylinders and being
folded afterwards by the fold-former.
Instead of returning the top tapes that pass over the fold-former above the
sheets by means of a series of guide pulleys which take up room besides looking
complicated, I place a section of a tube cut longitudinally into three, or a similar
rounded piece of metal, a little above the converging edges of the fold-former
and parallel to its edges. The return tapes slide over these rounded pieces of
metal and are returned to their places on the conveyance cylinder. Flat strips
of metal may be placed at a suitable angle on these rounded sides to act as guides
for the tapes.
In a web printing machine it is always desirable that the web while it is pass-
ing over the second blanket cylinder and receiving the last impression, should
not be in contact with the blanket cylinder for any great distance.
In my particular arrangement of printing cylinders I secure that while the
web is receiving the final impression it is only in contact with the blanket
cylinder for a small part of its circumference.
This obviates set-off and also saves strain on the paper and prevents breakages.
The manner in which this is carried into effect in a two-roll machine having a
bottom printing mechanism and a top printing mechanism is as follows:-
The inking mechanism of the first side in the lower press is arranged practi-

page_text: cally in a vertical position with the stereotype cylinder at the top. The first
blanket cylinder is in the same horizontal plane as its co-acting stereotype
cylinder. A horizontal line passing through the axes of the first stereotype and
first blanket cylinders passes through the point of contact between the second
stereotype cylinder and the second blanket cylinder. The second inking mech-
anism slopes upward at an angle so as to allow the printed web to be carried
upwards to the top of the fold-former. The inking mechanism of the first side
in the top press and the corresponding stereotype and blanket cylinders are all
practically in the same horizontal plane.
By the arrangement above described the web of paper has only a very short
dwell on the set off blanket cylinder in both top and bottom presses.
In the accompanying drawings,—
Figure 1 is a general diagrammatic elevation of a machine in which my in-
vention is embodied.
Figure 2 is a general plan of same but with the mechanism for printing the
first side of the web in the top press and the corresponding inking mechanism
removed.
Figure 3 is a sectional view on a larger scale of the cutting and associating
mechanism the parts being arranged to collect two or more sheets before fold-
ing.
Figure 4 is a similar view to Figure 3 but with the parts so arranged that
each sheet or set of sheets is cut and passed on without collecting."
5+
Figure 5 is a similar view to Figure 3 but showing the cutting and collect-
ing mechanism at a different period of the cutting and collecting operation.
Figure 6 is a partial front view and Figure 7 a side view of the fold forming
mechanism.
The particular arrangement of the two printing presses in relation to one
another and of the different cylinders in the combined machine are best seen
in Figure 1.
The first stereo cylinder 1 of the lower press is placed immediately above the
ink cylinder and inking mechanism 5, 5 and its upper surface is fully exposed
for handiness in putting on the stereo plates. The first blanket cylinder 2 is
in the same horizontal plane as its stereo cylinder 1 while the second pair of
stereo and blanket cylinders 3 and 4 are in a vertical plane a line passing through
the centres of 1 and 2 touching the point of contact between them.
The second inking mechanism 6, 6 slopes upward in order to leave room for
the folding mechanism. The top press is arranged with the mechanism for
printing the first side of the web in a horizontal plane, the mechanism for print-
ing the second side is also in a horizontal plane but it is as much lower as allows
the blanket cylinder of the second side to go immediately under the blanket
cylinder of the first side thereby shortening the machine and providing space
underneath the first printing mechanism for the extra pair of cutting cylinders 7
and 8.
The rolls of paper A B are mounted one above the other on the outside of the
machine as shewn, and the course of the webs of paper C and D as they pass
through the respective presses is clearly indicated. The lower press is driven
by any well known means and the upper press receives its motion from the train
of gearing 9 and 10.
A feature of the invention is the means employed for changing the speed of
the top press to half the speed of the lower press or back again to the same speed.
This is effected as follows:-The gear wheel 11 which is driven by the wheel 10
runs loose on the end of the stereo cylinder axle 12. In front of this wheel on
the same axle is keyed a larger wheel 13. The wheel 14 also runs loose on the
blanket cylinder shaft 16. In front of this wheel on the same axle is another
loose wheel 15 revolving on the axle as a stud. It will be seen that these
wheels 11, 14, 15 when not connected up will revolve without driving the top
machine.

page_text: In order to run the top machine at the same speed as the bottom one, a bolt 17
is passed through a hole in wheel 13 and screwed into a corresponding hole in
wheel 11. The loose wheel 11 thereby carries with it the wheel 13 because they
are fastened together by the bolt 17. As wheel 13 is keyed to the shaft motion
is thereby communicated to the top machine through the stereo cylinder 19 and
the gearing 20 on the opposite end of the shaft.
The wheels 14 and 15 merely run loose when the top press is thus made to
run at the same speed as the bottom press.
In order to run the top press at half the speed of the bottom press the bolt 17
is taken out of wheels 11 and 13 and put into wheels 14 and 15 as shewn at 16.
This allows the loose wheel 11 to drive the loose wheel 14 and as wheel 15
is bolted to wheel 14 the motion is carried through those wheels back to wheel 13
which is keyed on the axle. As the wheel 13 has double the number of teeth
that there is in wheel 15 the speed of the top press is thereby reduced to one
half of that of the bottom press.
This arrangement is much more simple and safe than the usual arrangement
in which wheels are taken off and others put on to change the speed. It is only
necessary to have one bolt to fasten the wheels together and that bolt has only
to be removed from one set of wheels to the other set to change the speed.
There is therefore no risk of the attendants locking the mechanism and
attempting to start with the result that damage is caused.
The inking mechanism may be of any kind suitable for the work the machine
has to do.
The manner of associating the webs is shewn in Figure 1 and more in detail
in Figures 3, 4 and 5. The web from the bottom press after it leaves the last
pair of printing cylinders passes the registering roller 21. It is then conveyed
preferably by margin tapes 21" to the pair of drawing rollers 22 and 23. These
rollers are made with an equal number of longitudinal flutes in them and the
lower one 23 is spring seated and made adjustable in relation to the top one by
the nuts 24. 25 and 26 are a pair of ordinary cutting cylinders, the per-
forator 25 being placed in the bottom cylinder and the bolster 26 in the upper
one. The cylinder 26 also carries a rock shaft 28 which operates the pins 28
immediately behind the perforating bolster in the cylinder. 27 is a conveyance
cylinder which carries a rock shaft 29 and a set of pins 29. The pins both in
this cylinder and in the upper cutting cylinder are operated by the cam 30 which
is hinged on the axle of the cylinder 25. This cam has double ends 31-32 and
it is operated by the box cam 33 in the cross shaft.
The cylinders 25, 26 and 27 are all of one size and preferably half the size
of the printing cylinders of the machine and they make two turns for one turn
of the stereo cylinders. The cylinder 26 can be caused either to cut off and
pass on each sheet singly that is without collecting or to collect the whole pro-
duct of the machine. When it is desired to cut off and pass on each sheet or
set of sheets singly without collecting the cam 30 has to be made stationary.
This is done by taking out the bolt stud of the cam roller 34 (see Figure 4)
thereby rendering this cam inoperative. The same bolt is then screwed through
the framework 35 into the lug of the cam 32 as is also seen in Figure 4. By
using the same bolt and making it of any special form, the risk of the cam being
bolted to the framework at 35 while the cam 30 is not disconnected and thus
inevitably causing a breakage of the mechanism is avoided.
The leading edge of the sheet after it passes the perforator is carried round
by the pins 28". When these pins arrive at the nearest point of contact with
the conveyance cylinder 27, the pins 28 are withdrawn by the cam 32 and the
pins 29ª in the conveyance 27 pick up the leading edge of the sheet and carry
it round into the bight of the tapes 36. The conveyance cylinder has a series of
tapes passing around it and from thence down the fold former when the sheet
will be longitudinally folded. The pins in the conveyance cylinder are with-
drawn at every revolution by the permanent cam 37.

page_text: This arrangement of the machine will produce single sheets which might be
a four page newspaper if only the bottom press is used. If a half width web
is used in the top press also and it runs at the same speed as the bottom press
it will produce six page papers. Full width webs in top and bottom presses
would produce two sheets inset or eight pages.
When working the machine to obtain the above products the perforator 40
in the top printing press carried by cutting cylinders 38 and 39 is removed:
The printed web D from the top press passes through between the cylinders 38
and 39 under the registering roller 41 and from thence to the drawing rollers 22
and 23 where it is associated with the web from the lower press.
In order to obtain 4 sheets representing 16 pages of a newspaper or the full
product of the top and bottom presses, the manner of operating the pins in the
collecting and conveyance cylinders has to be changed. The cam 30 has to be
released by the removal of the bolt at 35 which bolt is then inserted into the box
cam roller 34 thereby allowing the cam 30 to be rocked on its pivot at 25.
:
Figure 5 shows the pins 28 on cylinder 26 carrying round the leading end of
the sheet past the pins 29" in the conveyance cylinder 27. The cam 33 is round
with its highest side at the top. This rocks the double cam 31 and 32. The
cam 32 is set back to the left and thus allows the cam roller on the pin shaft 28
to pass without withdrawing the pins. When the cam 32 is out of contact
cam 31 is set forward so that the cam roller on pin shaft 29 is made to withdraw
the pins 29 inside the conveyance cylinder 27 as they pass the point of contact.
The sheets are thereby held by the pins on the collecting cylinder 26 and car-
ried round to the point of contact with cylinder 25 when the second lot of sheets
is impaled on the pins above the first lot. By the time the leading edge of the
collected sheets on the cylinder has been carried round to the point of contact
with the conveyance cylinder (see Figure 5), the box cam 33 has so far advanced
that the double cam 30 has been rocked to the right hand. This causes the
pins 28ª in the collecting cylinder to withdraw while the pins 29 in the con-
veyance cylinder seize hold of the leading edge of the sheets and transfer them
to the conveyance cylinder by which they are passed on to the longitudinal
folding mechanism. The arrangements already described will produce issues of
one sheet or 4 pages, one and a half sheets, or 6 pages, 2 sheets or 8 pages, and
4 sheets or 16 pages. In order to obtain products of two and a half sheets or
10 pages and 3 sheets or 12 pages the top printing press is arranged to run at
half speed in the manner I have already explained. The 10 page size is obtained
by using a full width web on the bottom press and a half width web on the
top press and a twelve page product is obtained by using two full width webs.
The same arrangement of the mechanism will produce either size and the fol-
lowing description will refer to both.
The perforator 40 Figure 3 is put into the cylinder 39. This is made to
perforate the web from the top press but not to completely sever it. The paper
after it passes the cylinders 38 and 39 is carried by top and bottom sets of end-
less tapes 44 to the breaking and conveyance cylinder 42.
The tapes 44 run at the same surface speed as the bottom press and the folder
mechanism while the web from the top press is only advancing at half speed..
The two sets of tapes are kept a little distance apart to prevent smearing the
freshly printed sheet.
The leading edge of the sheet is timed to reach the bight of the tapes between
cylinders 42 and 45 so that the projection 43 in the cylinder 42 nips the sheet
on its unprinted margin on the cylinder 45 and thereby completely severs the
sheet from the web and advances it down to the convevance cylinder 27 where
it is timed to join the two sheets which were produced in the lower press in the
time the one sheet was produced from the top press.
It is found in practice in conveying sheets by means of tapes any distance
after they are cut off from the web that they are ant to lose time and cause the
fold to be irregular. In order to obviate this I increase the diameter of the

page_text: rollers which drive the tapes, lap the tapes around these rollers about three
fourths or more of their surface and place these rollers as near to the top of
the fold former as possible.
The upper run of tapes 36 which passes over the fold former is driven by
the conveyance cylinder 27 around which they pass. The bottom run 36 pass-
ing down the former is driven by the cylinder 42, these cylinders being of the
same diameter as the cutting cylinder. In order to return the top run of tapes
to the conveyance cylinder 27 adopt new and novel means, Instead of return-
ing the tapes to the driving cylinder by a series of tape pulleys set at several
angles as is usual and thereby crowding the folder. I place a segment of a
tube or similar rounded device above the angle edges of the fold former and
parallel thereto leaving a space of about half an inch between the underside of
these tube segments and the edge of the former to allow the paper to pass between
between them.
The tapes after passing down the sides of the former and around the drawing
or folding rollers are led over these tube segments which form a convenient and
suitable guide to lead the tapes back to the conveyance cylinder or driving
roller above the fold former.
Figure 6 shows a front view of one half of the fold former and Figure 7 a
side view. The tube segments are shewn at 46 being represented as broken
away in the middle to shew the side of the fold former 47 itself and the tapes
in their downward course at 36*.
The tube segments 46 thus act as guides for the return of the top tapes 36
the tapes sliding over the rounded and smooth surface of the guides. As the
guides are only a little way above the edge of the former 47 over which the
tapes carry the sheets, the tapes returning over these guides practically return
in line with the advancing tape any tendency of the tape to wander out of its
course is corrected by the flanged tape pulleys 50 on the rod 48. 49 represents
one of the drawing or folding rollers around which the tapes 36 pass and from
which they are led up over the tube sections 46.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
1. In a two web rotary printing machine having a lower printing mechanism
and an upper printing mechanism, the combination of (a) the first stereo
cylinder and first blanket cylinder of the lower printing mechanism, said
cylinders being in the same horizontal plane, (b) the second stereo cylinder and
second blanket cylinder of said printing mechanism in the same vertical plane
and so disposed relatively to the first stereo and blanket cylinders that a line
passing through the centres of said last named cylinders touches the point of
contact between said second stereo and blanket cylinders (c) the first stereo
cylinder and first blanket cylinder of the upper printing mechanism said cylin-.
ders being in the same horizontal plane, () the second stereo cylinder and second
blanket cylinder of said printing mechanism said cylinders being in the same
horizontal plane but much lower than the plane of the first stereo and blanket
cylinders of said upper printing mechanism and the second blanket cylinder
being immediately below the first blanket cylinder of said printing mechanism, (e)
roll carriers at one end of the combined machine, (f) associating and folding
mechanism at the other end of the machine, and (g) means whereby the webs
are carried from the roll carriers to the two printing mechanisms respectively
and from said mechanisms to the associating and folding mechanism, substan-
tially as set forth.
2. In a two web rotary printing machine the combination with the gear
wheels 9 and 10 which transmit motion from a lower printing mechanism to an
upper printing mechanism, of a gear wheel 11 loose on the stereo cylinder
axle 12 of said upper printing mechanism and meshing with said wheel 10, a

page_text: heel 13 keyed on said axle 12, a wheel 14 loose on the blanket cym
f said upper printing mechanism, a wheel 15 also loose on said axle 16 and a
polt hole in each of said wheels 11, 13, 14 and 15 whereby when a bolt is in-
erted into the holes of wheels 11 and 13 the two printing mechanisms run at
he same speed and when a bolt is inserted into the holes 14 and 15 the upper
printing mechanism runs at half the speed of the lower printing mechanism,
substantially as set forth.
3. In a two web rotary printing machine in which one printing mechanism
can be driven at either the same speed as or at half the speed of the other print-
ing mechanism, an arrangement whereby the respective webs can either be
associated in an uncut state, then cut together transversely and then the cut and
associated sheets be folded longitudinally, or the respective webs can be cut
separately, the cut sheets be then brought together and associated and then
folded longitudinally, as required according to the particular product to be
obtained, substantially as set forth.
4. In a rotary web printing machine the combination with the mechanism for
cutting the printed web, of a cam 30 with two ends 31 and 32 operating the
cutting mechanism, a cam 33 operating said cam 30 a cam roller 34 working in
said cam 33 and a bolt for securing said roller but capable of being removed and
placed into the cam end 32 whereby said cam 30 can be made as required either
inoperative or operative and the cutting cylinder therefore caused either to cut
and pass on each sheet or set of sheets singly without collecting or to collect
the sheets or sets of sheets, substantially as described.
5. In the folding mechanism of a rotary web printing machine, the com-
bination with the fold former, the tapes which carry the sheets down said former
and the drawing or folding rollers below said former of tubular segments above
the edges of said former and parallel therewith, said tapes passing over said
tubular segments in their upward travel after passing around said drawing or
forming rollers, substantially as and for the purpose set forth.
