PROVISIONAL SPECIFICATION.
An Improved Rotary Printing and Ruling Machine.
I, JULES MICHAUD, of 96 Rue d'Assas, Paris, France, Engineer, do hereby declare
the nature of this invention to be as follows:-
The present invention relates to an improved rotary printing press, which is more
particularly adapted to bookwork and also to ruling; the sheets printed may be of
different sizes both in the direction of the development of the cylinders as well as in
the direction of the width of the machine.
In the accompanying drawings:-
Fig. 1, is a longitudinal section of the complete machine.
Fig. 2, a longitudinal section of the cutting cylinders and shows the arrangement
of gearing for driving same at a varying speed.
Figs. 3 and 4 are both sections showing the action of the additional grippers 24
with which the accumulating cylinder is provided.
Fig. 5, is a section of the accumulating cylinder showing the action of blades 31
for driving out the set of sheets from the accumulating cylinder for delivery; and also
shows an arrangement for enabling the gripping cylinder which takes the printed
sheet from the second impression cylinder, to serve as an accumulating cylinder.
Fig. 6, is a section showing an arrangement in which the gripping cylinder which
takes the printed sheets from the second impression cylinder, acts as a folding
cylinder.
Fig. 7, is a section showing an arrangement of folding cylinders to which the sheets
are supplied by the gripping cylinder which takes the printed sheets from the second
impression cylinder.
The paper coming from a reel (Fig. 1) passes over a roller 2, then over a cylinder 3.
It is upon this cylinder that the ruling is effected by means of discs 4, of which the
number and the arrangement on the rod 5 which carries them, vary according to the
nature of the work to be executed.
The paper after passing over a roller 6 enters between the two rollers 7 and 8 which
serve to carry it forward.
I may heat the rollers 2, 3 or 6, by steam or otherwise, so as to ensure a more rapid
drying of the ruling.
The rate of feed of the paper is regulated by the speed of roller 7, against which
bears the rollers 8 and ensures the forward movement of the paper. The paper then
passes between the two cutting cylinders 9 and 10, which make one revolution for
each revolution of the printing cylinders, and thus cut sheets of which the size varies
according to the variations of speed of roller 7.
It will be noticed that the cutting apparatus is placed at the foot of the machine,
the objects being to prevent the dust resulting from the cutting from falling upon the
inking rollers and upon the impression cylinders, and also to leave the front of the
machine completely open so as to facilitate access thereto.
In order that the paper may be cut well, it is necessary that the surface speed of the
cutting cylinders at the moment of cutting, should be practically the same as the rate
of travel of the paper, otherwise the cutting blade or saw carried by one of the
cylinders, will make distinct marks on the paper, by meeting same at a different speed
than its own, before the moment for cutting. This result may be obtained by having
as many pairs of cylinders 9 and 10 as it is desired to produce different sized sheets
in the direction of the development of the cylinders, the development of each of the
cylinders of these pairs being equal to the length of each of the different sizes. For
this purpose it will be necessary, as shown in Fig. 1, that the centres of the

page_text: cylinders 9, 10, may vary their position so as to approach each other when smaller
cylinders are used, and to recede from each other when larger cylinders are used.
In Fig. 2, I have shown another arrangement, which enables the same results to
be obtained without having to change the cylinders 9, 10. For this purpose,
instead of a uniform movement which they usually have, I give to these cylinders
a periodically varying movement, the period being one revolution of the cylinders.
This movement is such that the maximum speed corresponds to the speed with which
the paper travels in the case of the largest size, and that the minimum corresponds
to the speed of the paper in the case of the smallest size to be made.
With this arrangement if it is desired for example to make the smallest sized
sheet, it suffices for the cutting blade or saw of cylinder 10 to come in contact
with cylinder 9 at the moment when the cylinders revolve at their slowest speed.
The largest and all intermediate sizes between the smallest and largest, may in
the same way be produced by causing the moment of cutting to correspond to
the greatest speed of the cylinders or to an intermediate speed.
Fig. 2, shows an arrangement for driving the cylinders 9, 10, so as to produce the
varying speed.
Shaft 32 actuated by the machine itself makes one rotation for each revolution
of the printing cylinders; it carries a bevel pinion gearing with a similar pinion
mounted on the same axis as the wheel 33. This wheel 33 gears with a wheel 34
of the same diameter. On the axis of the wheel 34 is mounted a wheel 35 gearing
with another wheel 36. The two wheels 35 and 36 must not be circular, their
pitch line being an ellipse, and they revolve round one of the foci of such ellipse.
On the axis of the wheel 36 is mounted a circular wheel 37 gearing with the
wheel of the same diameter on the cylinder 10.
The wheel 35 therefore imparts a variable movement to the cylinder, the differences
of speed being determined by the differences of the axis of the ellipse.
In practice the wheels 35 and 36 may be circumferences of which the centre of
rotation will be a small distance from the centre of the figure, the necessary play
being allowed for the teeth of the gearing.
To impart to the cylinders the speed suitable for the moment of cutting, it is only
necessary to dismount the wheels 36 and 37, then to cause the cylinders 9, 10, to
rotate the required distance and replace the two wheels 36 and 37, the wheel 36
always engaging wheel 35 at the same point, while wheel 37 will gear with the
wheel of cylinder 10 at a different point to what it did before.
In order to avoid the dismounting of the wheels 36 and 37, 1 may form in the
cylinder 10 different grooves to receive the cutting blade or saw. The effect will
be precisely the same.
In the Specification of Patent No. 2772 dated 25th February 1886, granted to
Alexander Melville Clark, as a communication from Auguste Hippolyte Marinoni and
myself, an arrangement is described in which the paper caused to form a slackness
in front of the cutting cylinders, so that the paper is only carried forward by the
latter at the moment of cutting.
I may apply this arrangement to my present invention.
The sheets cut pass between the cords or tapes 11 and 12, which carry them to the
cylinder 13, the grippers of which seize same.
The cords 11 and 12 pass over rods mounted on movable pieces A, which are
articulated on the axes B, thus permitting all the cords to be raised and give access
to the cylinders carrying the blankets and the plates.
The largest sheet which the machine can print in the direction of the development,
is that equal to the development of cylinder 13 less a part of the space occupied by
the groove in which move the grippers; it will be seen by the foregoing description
that the machine will also print all sizes of sheets smaller than that of this largest
sheet.
The sheet seized by the grippers of the cylinder 13, is printed by cylinder 14 on
one side, then delivered to the grippers of cylinder 15, which in its turn carries it
forward, and is printed on the other side by cylinder 16. The rollers 17 and 18

page_text: which bear upon cylinder 15, are cleaning rollers which serve to remove the off-set
deposited on such cylinder, and avoid the soiling which such deposit would produce.
The sheet printed on both sides is seized by the grippers of cylinder 19 and trans-
mitted to cylinder 20, which is called an accumulating cylinder; in the machine
shown in Fig. 1, the cylinder 20 has a development double that of the printing
cylinders. I employ this arrangement so as to have the flyers to receive the sheets
nearly vertical and to enable the delivery table to be raised, but I may employ a
cylinder of equal diameter, or of three, four or more times the diameter of the
printing cylinders.
Whatever the diameter of the accumulating cylinder may be, the arrangement
described for laying the sheets on this cylinder, and the means employed for
maintaining them there are entirely new.
The direct transmission of a sheet from the grippers 21 of cylinder 19, to the
grippers 22 of cylinder 20, necessitates that when cylinder 20 already carries a
sheet held by the grippers 22, the latter open before the two cylinders come in
contact, so as to penetrate into the groove of cylinder 19 without tearing the
sheet it carries, and also that the grippers of cylinder 19 open and penetrate into
the groove of the cylinder 20 without tearing the sheet that the latter has already
gathered it, therefore, follows that the sheets for a certain time are completely
abandoned on the two cylinders. In so far as the sheet on cylinder 19 is con-
cerned, this leads to no serious inconvenience, as the cords or tapes situated in
the blank spaces will suffice to support the sheet during the time it is abandoned by
the grippers. It is not the same with cylinder 20; not only does the first sheet tend
to detach itself from the cylinder by its weight, but further the weight of the second
sheet gathered is added to that of the first, then that of the third, of the fourth, etc.,
according to the number of sheets to be delivered at a time.
To remedy this inconvenience and to leave the cords 23 arranged in the blank
spaces to the simple function of supporting the tail or end of the set of sheets, I have
thought of placing in the groove of cylinder 20, the grippers 24 which are brought to
bear upon the sheets gathered by the cylinder, during the time that the grippers 22
remain open, and are lowered to seize a new one.
The bar 25 on which the grippers 24 are mounted is movable; it can oscillato
round the centre of the bar 27, on which are fixed the cheeks 28 which support
the bar 25.
The bars 25 and 27 carry at their ends cranks fitted with rollers 29 and 30, upon
which act cams.
When the grippers 22 are to seize the first sheet carried by the grippers of
cylinder 19. they open, penetrate into the groove of cylinder 19 and seize the sheet
abandoned by the latter at the moment when the forward edge of this sheet arrives in
the line of the centres of the two cylinders. During this time the grippers 24 have
remained at rest.
When the sheet has been well laid upon cylinder 20 by the grippers 22, the
grippers 24 which are then beneath the sheet begin to operate; they retire from
beneath the sheet of paper without opening, and move to a position in advance of the
forward edge thereof, as shown in Fig. 3. This backward movement results from
the combined action of the cams acting upon the rollers 29 and 30. It is such that
the gripper moves away without raising the sheet of paper placed over it, and con-
sequently without tearing it; before the grippers 22 again open, the grippers 24 are
raised under the action of the cam acting upon the roller 29 (Fig. 4), then by the
simultaneous action of the cams acting upon the rollers 29 and 30, they advance and
are lowered upon the sheet.
The grippers 22 are then raised and seize a new sheet, which they lay upon the
first.
The grippers 24 confined between the two superposed sheets, are withdrawn as
before without exercising any pressure upon either of the two sheets, and consequently
without tearing same. When the cylinder 20 has thus gathered the number of sheets

page_text: fixed, the set formed is driven out in front of the flyers by the blades 31, after having
been abandoned by the grippers 22 and 24, such blades being actuated at the proper
time in order to throw the set out, as shown in Fig. 5.
The cylinder 20 being of a diameter double that of the printing cylinders, on the
machine shown, carries two sets of grippers 22 and 24, and of blades 31, the operation
being the same for each set. There would only be one set of such organs if the
diameter of the cylinder 20 were the same as that of the printing cylinders, which as
above stated I may employ if desired.
I may if desired employ the cylinder 19 as an accumulating cylinder, in which case
it would carry the auxiliary grippers 24', (Fig. 5), operating in the same way as the
grippers 24, and which would support the set of accumulated sheets during the time
that the grippers 38 are opened to take a fresh sheet from cylinder 15. When the
desired number of sheets have been accumulated by the cylinder 19, the set would be
transmitted to the cylinder 20, and thrown out by it by means of the blades 31, in
front of the Byers, without the intervention of any cord passing round the cylinder 20,
to detach the sheets therefrom.
In the case where the printed sheets are intended to be folded, the cylinder 19 will
transmit them to a folder replacing the accumulating cylinder.
The cylinder 19 may be maile the folding cylinder, when in addition to the
grippers 21 (Fig. 6), it would carry a blade 39 which engages the middle of the sheet
in the second folding cylinder 40. The sheet is seized, folded in the middle by
blade 41 of cylinder 40, and conducted either to a third folding cylinder, or to rollers
according to the ordinary means.
The sheets being of variable dimensions, there will not always be the same distance
between the forward end of the sheet which is seized by the grippers 21, and its middle
which is to be caused by the blade 39 to engage the second folding cylinder.
In order, however, that the blade 39 always causes exactly the middle of the
sheet to engage the cylinder 40, the grippers 21 are mounted upon two cheeks 42,
movable round the axis of the cylinder 19, and which are fixed in different positions
according to the dimensions of the sheets, by which means it will be seen that
the grippers 21 can always be placed in a position (such as 21', for example) in
which the blade 39 will always cause the middle of the paper to engage the
cylinder 40.
The cylinder 19, even in the case where the sheets are to be folded, need not be a
folding cylinder, but may after seizing the sheet deliver it between two sets of cords
or tapes, or to another cylinder 40, which will then lead it to cords or tapes 42, 43,
which will carry it between the folding cylinders 44, 45 (Fig. 7).
As the cylinder 45 is to carry the folded sheet, it is very important that the forward
edge of the sheet descends truly between the two cylinders 44, 45, or in the direction
of the cylinder 44, for if it were to remain lying on the cylinder 45 it would engage
the folder without having received the first fold.
So as to ensure the forward end of the sheet being properly directed, I have
arranged in the cylinder 45 a bar 46, carrying blades which are brought to bear on
the edge of the cylinder at the part corresponding with the forward edge of the sheet.
As soon as the sheet arrives between the two cylinders, the blades of the bar 46 are
raised and throw the sheet in the direction of the cylinder 44. The sheet will remain
lying on this cylinder or will descend vertically according to the speed at which the
machine runs, until the folding blades come in contact. As the sheets are of varying
dimensions, and the first fold must always be made in their middle, it follows that the
forward end of the sheet does not always correspond to the same point on the
cylinder 45. I therefore mount the bar 46 on two movable cheeks 47, similar to
the cheeks 42 previously described. These checks 47 can be fixed in different
positions according to the dimensions of the sheets.
I can therefore always place the bar 46 in a position (such as 46', for example) in
which the blades it carries will throw the forward end of the sheet in the direction of
the cylinder 44.

with delivery of non-folded sheet.

COMPLETE SPECIFICATION.
An Improved Rotary Printing and Ruling Machine.
I, JULES MICHAUD, of 96 Rue d'Assas, Paris, France, 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:-
The present invention relates to an improved rotary printing press, which is more
particularly adapted to book work and also to ruling; the sheets printed may be of
different sizes, both in the direction of the development of the cylinders as well as in
the direction of the width of the machine.
In drawings filed with Provisional Specification :-
Fig. 1, is a longitudinal section of the complete machine.
Figs. 2 and 3, are both sections showing the action of the additional grippers 24
with which the accumulating cylinder is provided.
Fig. 4, is a section of the accumulating cylinder showing the action of blades 31
for driving out the set of sheets from the accumulating cylinder for delivery; and
also shows an arrangement for enabling the gripping cylinder which takes the printed
sheet from the second impression cylinder, to serve as an accumulating cylinder.
Fig. 5, is a section showing an arrangement in which the gripping cylinder which
takes the printed sheets from the second impression cylinder, acts as a folding
cylinder.
Fig. 6, is a section showing an arrangement of folding cylinders to which the sheets
are supplied by the gripping cylinder which takes the printed sheets from the second
impression cylinder.
The paper coming from a reel (Fig. 1) passes round a roller 2, then over a
cylinder 3. It is upon this cylinder that the ruling is effected by means of discs 4, of
which the number and the arrangement on the rod 5 which carries them, vary
according to the nature of the work to be executed.
The paper after passing round a roller 6, enters between the two rollers 7 and 8
which serve to carry it forward.
I may heat the rollers 2, 3 or 6, by steam or otherwise, so as to ensure a more rapid
drying of the ruling.
The rate of feed of the paper is regulated by the speed of roller 7, against which
bears the roller 8 and ensures the forward movement of the paper. The paper then
passes between the two cutting cylinders 9 and 0, which make one revolution for
each revolution of the printing cylinders, and thus cut sheets of which the size varies
according to the variations of speed of roller 7.
It will be noticed that the cutting apparatus is placed at the foot of the machine,
the objects being to prevent the dust resulting from the cutting from falling upon the
inking rollers and upon the impression cylinders, and also to leave the front of the
machine completely open so as to facilitate access thereto.
In order that the paper may be cut well, it is necessary that the surface speed of
the cutting cylinders at the moment of cutting should be practically the same as the
rate of travel of the paper, otherwise the cutting blade or saw carried by one of the
cylinders, will make distinct marks on the paper, by meeting same at a different speed
than its own, before the moment for cutting. This result may be obtained by having
as many pairs of cylinders 9 and 10 as it is desired to produce different sized sheets
in the direction of the development of the cylinders, the development of each of the
cylinders of these pairs being equal to the length of each of the different sizes.
For this purpose it will be necessary, as shown in Fig. 1, that the centres of the

page_text: cylinders 9, 10, may vary their position so as to approach each other when smaller
cylinders are used, and to recede from each other when larger cylinders are used.
In the Specification of Patent No. 2772 dated 25th February 1886, granted to
Alexander Melville Clark, as a communication from Auguste Hippolyte Marinoni and
myself, an arrangement is described in which the paper is caused to forin a slackness
in front of the cutting cylinders, so that the paper is only carried forward by the
latter at the moment of cutting.
I may apply this arrangement to my present invention.
The sheets cut pass between the cords or tapes 11 and 12, which carry them to the
cylinder 13, the grippers of which seize same.
The cords 11 and 12 pass over rods mounted on movable pieces A, which are
articulated on the axes B, thus permitting all the cords to be raised and give access
to the cylinders carrying the blankets and the plates.
.
The largest sheet which the machine can print in the direction of the development,
is that equal to the development of cylinder 13 less a part of the space occupied by
the groove in which move the grippers; it will be seen by the foregoing description
that the machine will also print all sizes of sheets smaller than that of this largest
sheet.
The sheet seized by the grippers of the cylinder 13, is printed by cylinder 14 on
one side, then delivered to the grippers of cylinler 15, which in its turn carries it
forward, and is printed on the other side by cylinder 16. The rollers 17 and 18
which bear upon cylinder 15, are cleaning rollers which serve to remove the off-set
deposited on such cylinder, and avoid the soiling which such deposit would produce.
The sheet printed on both sides is seized by the grippers of cylinder 19 and
transmitted to cylinder 20, which is called an accumulating cylinder; in the machine
shown in Fig. 1, the cylinder 20 has a development double that of the printing
cylinders. I employ this arrangement so as to have the flyers to receive the sheets
nearly vertical and to enable the delivery table to be raised, but I may employ a
cylinder of equal diameter, or of three, four or more times the diameter of the printing
cylinders.
Whatever the diameter of the accumulating cylinder may be, the arrangement
described for laying the sheets on this cylinder, and the means employed for
maintaining them there are entirely new.
The direct transmission of a sheet from the grippers 21 of cylinder 19, to the
grippers 22 of cylinder 20, necessitates that when cylinder 20 already carries a sheet
held by the grippers 22, the latter open before the two cylinders come in contact, so
as to penetrate into the groove of cylinder 19 without tearing the sheet it carries,
and also that the grippers of cylinder 19 open and penetrate into the groove of the
cylinder 20 without tearing the sheet that the latter has already gathered; it, therefore,
follows that the sheets for a certain time are completely abandoned on the two
cylinders. In so far as the sheet on cylinder 19 is concerned, this leads to no serious
inconvenience, as the cords or tapes situated in the blank spaces will suffice to support
the sheet during the time it is abandoned by the grippers. It is not the same with
cylinder 20; not only does the first sheet tend to detach itself from the cylinder by
its weight, but, further, the weight of the second sheet gathered is added to that of
the first, then that of the third, of the fourth, etc., according to the number of sheets
to be delivered at a time.
To remedy this inconvenience and to leave the cords 23 arranged in the blank
spaces to the simple function of supporting the tail or end of the set of sheets, I have
thought of placing in the groove of cylinder 20, the grippers 24, which are brought
to bear upon the sheets gathered by the cylinder, during the time that the grippers 22
remain open, and are lowered to seize a new one.
The bar 25 on which the grippers 24 are mounted is movable; it can oscillate
round the centre of the bar 27, on which are fixed the cheeks or arms 28 which
support the bar 25.
The bars 25 and 27 carry at their ends cranks fitted with rollers 29 and 30, upon
which act cams 50 and 51, as shown in Figs. 2 and 3.

page_text: When the grippers 22 are to seize the first sheet carried by the grippers of
cylinder 19, they open, penetrate into the groove of cylinder 19 and seize the sheet
abandoned by the latter at the moment when the forward edge of this sheet arrives in
the line of the centres of the two cylinders. During this time the grippers 24 have
remained at rest.
When the sheet has been well laid upon cylinder 20 by the grippers 22, the
grippers 24, which are then beneath the sheet begin to operate; they retire from
beneath the sheet of paper without opening, and move to a position in advance of the
forward edge thereof, as shown in Fig. 2. This backward movement results from the
action of the cam 50 upon the roller 30. It is such that the gripper moves away
without raising the sheet of paper placed over it, and consequently without tearing it;
before the grippers 22 again open, the grippers 24 are raised under the action of the
cam 5 acting upon the roller 29 (Fig. 3), then by the simultaneous action of the
cams 50 and 51 acting upon the rollers 29 and 30, they advance and are lowered
upon the sheet.
The grippers 22 are then raised and seize a new sheet, which they lay upon the
first.
The grippers 24 confined between the two superposed sheets, are withdrawn as
before without exercising any pressure upon either of the two sheets, and consequently
without tearing same. When the cylinder 20 has thus gathered the number of sheets
fixed, the set formed is driven out in front of the flyers by the blades 31, after having
been abandoned by the grippers 22 and 24, such blades being actuated at the proper
time in order to throw the set out, as shown in Fig. 4.
The cylinder 20 being of a diameter double that of the printing cylinders, on
the machine shown, carries two sets of grippers 22 and 24, and of blades 31, the
operation being the same for each set. There would only be one set of such organs
if the diameter of the cylinder 20 were the same as that of the printing cylinders,
which as above stated I may employ if desired.
I may if desired employ the cylinder 19 as an accumulating cylinder, in which
case it would carry the auxiliary grippers 24', (Fig. 4) operating in the same way as
the grippers 24, and which would support the set of accumulated sheets during the
time that the grippers 38 are opened to take a fresh sheet from cylinder 15. When
the desired number of sheets have been accumulated by the cylinder 19, the set
would be transmitted to the cylinder 20, and thrown out by it by means of the
blades 31, in front of the flyers, without the intervention of any cord passing round
the cylinder 20, to detach the sheets therefrom.
In the case where the printed sheets are intended to be folded, the cylinder 19 will
transmit them to a folder replacing the accumulating cylinder.
The cylinder 19 may be made the folding cylinder, when in addition to the
grippers 21 (Fig. 5), it would carry a blade 39 which engages the middle of the
sheet in the second folding cylinder 40. The sheet is seized, folded in the middle by
blade 41 of cylinder 40, and conducted either to a third folding cylinder or to rollers
according to the ordinary means.
The sheets being of variable dimensions, there will not always be the same distance
between the forward end of the sheet which is seized by the grippers 21, and its
middle which is to be caused by the blade 39 to engage the second folding
cylinder.
In order, however, that the blade 39 always causes exactly the middle of the
sheet to engage the cylinder 40, the grippers 21 are mounted upon two cheeks or
arms 42, movable round the axis of the cylinder 19, and which are fixed in different
positions according to the dimensions of the sheets, by which means it will be seen that
the grippers 21 can always be placed in a position (such as 21', for example) in
which the blade 39 will always cause the middle of the paper to engage the
cylinder 40.
The cylinder 19, even in the case where the sheets are to be folded, need not be
a folding cylinder, but may after seizing the sheet deliver it between two sets of cords

page_text: or tapes, or to another cylinder 40, which will then lead it to cords or tapes 43, 43*,
which will carry it between the folding cylinders 44, 45 (Fig. 6).
As the cylinder 45 is to carry the folded sheet, it is very important that the
forward edge of the sheet descends truly between the two cylinders 44, 45, or in the
direction of the cylinder 44, for if it were to remain lying on the cylinder 45 it would
engage the folder without having received the first fold.
So as to ensure the forward end of the sheet being properly directed, I have
arranged in the cylinder 45 a bar 46, carrying blades which are brought to bear
on the edge of the cylinder at the part corresponding with the forward edge of
the sheet. As soon as the sheet arrives between the two cylinders, the blades of
the bar 46 are raised and throw the sheet in the direction of the cylinder 44.
The sheet will remain lying on this cylinder or will descend vertically according
to the speed at which the machine runs, until the folding blades come in contact.
As the sheets are of varying dimensions, and the first fold must always be made
in their middle, it follows that the forward end of the sheet does not always
correspond to the same point on the cylinder 45. I therefore mount the bar 46 on
two movable cheeks or arms 47, similar to the cheeks or arms 42 previously described.
These cheeks or arms 47 can be fixed in different positions according to the
dimensions of the sheets.
I can therefore always place the har 46 in a position (such as 461, for example)
in which the blades it carries will throw the forward end of the sheet in the direction
of the cylinder 44.
I may construct machines on this system with both a folder, and an accumulator
with delivery of non-folded sheets.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The improved rotary printing and ruling machine consisting in the com-
bination of ruling discs 4 mounted on a shaft 5 and resting upon cylinder 3 over
which a web of paper is caused to pass on its way to the printing cylinders; feed
rollers 7 and 8 the speed of which may be varied; changeable cutting cylinders 9
and 10 between which the web of paper passes and is cut into sheets; cords 11 and 12
passing over rods mounted on the arms A hinged at B to the frame of the machine,
and which cords serve to convey the cut sheets to the printing cylinders; printing
and impression cylinders 13 and 14, and 15 and 16; cylinder 19 taking the sheets
from cylinder 5 by grippers 21, and transferring them to an accumulating cylinder;
and an accumulating cylinder 20 provided with grippers 22 and 24 operated by cams,
so that when one set of grippers is raised the other set still bolds the heads of the sheets
against the accumulating cylinder, all substantially as specified.
2. The combination with a rotary web printing machine of a cylinder over which
the continuous web of paper is caused to pass on its way to the printing machine,
and of a set of ruling discs resting upon such cylinder, substantially as specified.
3. The combination with a rotary printing machine of cutting cylinders 9 and 10
arranged at the base of the machine, and of tapes 11 and 12 passing over bars
carried by movable arms A, and conveying the sheets cut from a web of continuous
paper from the cutting to the printing cylinders, so that when arms A are raised
the front of the printing machine will be entirely open and allow free access to the
printing and impression cylinders, substantially as specified.
4. The combination with a rotary printing machine of an accumulating cylinder
