Improvements in Printing Machines for Printing on One Side only o
Continuous Paper or Tissue.
I, EMILE PREBAY, of 191, Rue de l'Université, Paris, France, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in printing machines for printing on
one side only of continuous paper or tissue in which the paper to be printed
upon is maintained on the cylinder during the printing by means of a pneumatic
holding device.
The present improvements have for their object to simplify the construction
of such machines, to improve the action thereof, and to render them more accurate,
regular and faultless in working.
We will describe the said improvements with reference to the accompanying
drawing, which shows a printing machine with pneumatic grippers to which
the said improvements are applied.
Fig. 1 shows a complete side elevation of the machine, Figs. 2 & 3 are
detail sectional views of the printing cylinder, Fig. 4 is a part plan view
of the arrangement for actuating the roller for supplying the continuous sheet
to be printed upon, and that for receiving the printed sheet, as also the roller
which supplies the blotting paper. Fig. 5 is a part elevation of the printing
cylinder shewing the device for regulating one of the register pins. Fig. 6
shews a section on line A-A Fig. 5; Fig. 7 shews the arrangement of the
driving pulley of the receiving roller.
In the machines of the kind indicated, as heretofore constructed, the printing
cylinder is provided with a single pneumatic gripper and the continuous sheet
to be printed upon is maintained applied to the cylinder by causing it after
leaving the cylinder to pass over a suitably arranged guide roller having a
drawing action.
This arrangement is defective in several respects, and in particular because
smudging is always to be feared, notwithstanding the provision of more or less
complicated mechanical devices for effecting the cleaning of the roller because
t is the freshly printed side of the sheet which passes over such roller.
According to our invention we obviate this inconvenience by doing away with
he said guiding and drawing roller, and we ensure the effective adhesion of
he sheet upon the cylinder by providing this with two pneumatic grippers, of
hich one at least is in action, at any given moment. The sheet being thus-
lways maintained upon the cylinder by at least one gripper, it cannot slip or
ecome displaced thereon, so that all difficulty as regards the registering is
voided.

page_text: Fig. 1 shews clearly the path followed by the paper sheet to be printed upon,
as also the form given to the framing for obtaining in the simplest manner.
the guiding of the sheet during its travel.
The continuous sheet f to be printed upon unrolls from the supply roller a,
passes over guide bars such as 16, 17, 18, 19, 20, and over the guide roller 21
whence it passes round the printing cylinder and thence to the receiving
roller, in passing over guides such as e, 22, 23, 24, 25, fixed at the top of the
framing.
On the printing cylinder the sheet is securely held by the suckers or
pneumatic grippers g,. 28, Figs. 1 to 3, of which one at least is in action thereon
at any given moment. For this purpose a vacuum is produced in the suckers
when they are in the position 1, in order that they may attract the sheet f and
the exhaust is maintained until the sheet becomes detached at 2 in passing
tangentially away from the cylinder to the guide e. It will be observed that
while one of the suckers (g for example) passes from 1 to 2, the other, 28, passes
to 1 where it enters into action, so that this sucker will already have commenced
its action before the other ceases to hold the sheet, and the latter is consequently
always held by pneumatic action.
The exhaust is produced in the suckers as follows:
The shaft of the cylinder c is hollow at both ends, at and at 29 Fig. 2,
and the suckers g, 28, are connected respectively to the channels and 29 by
tubes, 30, the said channels being in communication by the tubes 4, 31, with
an exhausted chamber. On the tubes 7, 3.1 are mounted cocks m, 32, Fig. 1, which
are respectively actuated by cams n, 33, fixed on the shaft which actuates the
carriage and inking apparatus.
The cam is so formed and fixed that the cock m is opened immediately
before the platten commences its working stroke, the sucker being then at 1;
at the same time the bar h is pressed down upon the sheet so as to press this
upon the sucker, after which it is at once raised again; the cam n afterwards
closes the cock m as soon as, in consequence of the rotation of the cylinder c,
the sucker guas passed the position 2, in which the sheet f has passed away
from it.
The cam 33 is so formed and fixed that it causes the cock 32 to open as soon
as the sucker 28 arrives at 1 during the rotation of the cylinder c, so that this
sucker holds the paper sheet without requiring the bar to be applied thereto;
the cam 33 afterwards closes the cock 32 when the sucker 28 has arrived at 2.
It will be seen at Fig. 1 that the sheet f which unrolls from the roller a
hangs free between this and the guide bar 16. It is, namely, indispensable that the
sheet should have some slack in order to have full liberty to place itself squarely
on the cylinder c. In order, however, that it shall unroll correctly, it is necessary
to weight it somewhat, by placing a small wooden roller & in the loop of the
hanging part.
C
In order that the slack of the sheet be maintained during the printing
operation, it is indispensable that the speed of unrolling of the sheet shall
always be practically equal to the speed of rolling up on the roller d. For
obtaining this result, the relative speeds of the rollers d and a are controlled as
follows The receiving roller d is driven by a belt o Figs 1 & 7 which
is actuated through a pinion p, by one of the toothed rings 9 on the cylinder
which serve or effecting its rotation by the forme carriage. The belt is
suitably stretched by a weight r, it passes round a pulley 34 on the shaft of
the roller. When the receiving roller has become wound to its full extent
with the continuous sheet it is necessary to replace it by an empty one; also
in order that the same pulley 34 may serve successively for all the receiving
rollers it is not mounted directly upon the axis 36 of the roller, but upon a
sleeve 35 that is slid on the left hand end of this axis, which is there formed
with a flat surface fitting a corresponding flat surface in the bore of the sleeve,
Bo that the axis carries the sleeve round with it.

page_text: As the belt o is driven with a constant speed while the roller d has to 1
rotated with a gradually decreasing speed in proportion as its diameter increase
by the winding on of the printed sheet, the pulley 34 is not fixed on the sleeve 3
but is connected thereto by a friction clutch capable of regulation, whereby th
5 winding on of the sheet f can be effected at a tension regulatable at will.
This friction clutch is shewn at Fig. 7. It will be seen that the sleeve 35
has a circular collar 37, formed on it, and has a screw thread formed on part o
its length.
On this sleeve is slid first a leather washer 38, which bears against the collar
0 then the pulley 34, then a leather washer 39, a loose metal collar 40, and a
strong helical spring 41, against which presses a wheel-nut 42, screwed upor
the end of the sleeve. A screw 43, which passes through the loose collar 40
and takes into a groove 49 of the sleeve, allows the collar a certain amount of
play in the direction of the length of the sleeve, but obliges the latter to turn
with the collar.
In screwing the nut 42, upon the sleeve, the spring 41, is compressed, and
this consequently presses the collar 40 with greater or less force towards the
fixed collar 37 thus producing greater or less frictional adhesion between these
parts and the pulley-boss through the medium of the leather washers 38
and 39.
For regulating this adhesion and consequently the tension under which the
sheet is wound up on the roller, it suffices to turn the wheel-nut 42 more
or less in one direction or the other.
The receiving roller in its turn controls the feeding roller a, by means
of an endless cords Figs. I and 4 which passes over two grooved conical pullies, t
and fixed on the axes of the two rollers.
By this arrangement it is always easy to regulate at will the speed at which
the sheet is unrolled, as it only requires for this purpose to shift the cord s
from one groove to another of the two pulleys.
Fig. 4 shews this arrangement, as also an arrangement of regulating screws v
for regulating the transverse positions of the rollers, so that the unrolling and
rolling up of the sheet may always take place correctly.
It will be seen that as the feed roller a is placed in the machine in a relatively
elevated position, the placing thereof may present some difficulty as this roller
is sometimes very heavy. For facilitating such placing we have arranged the
supports of the roller so that they may be lowered for placing thereon a filled
roller, after. which they are raised into position by means of suitable toothed
gearing arranged so that this operation is easily effected.
This arrangement is shewn at Fig. 1. It will be seen that the bearings
that receive the axis of the roller a are formed on arms which are fixed upon
shaft y mounted in the framing. This shaft can be rotated by a crank
bandle to which it is connected by a train of toothed wheels 3, 4.
While the machine is at work the arms r are fixed in their vertical position
thumb nuts 5. When the roller requires to be changed, these nuts are
emoved and the arms are lowered until the bars 6 fixed thereto bear against
n abutment bar which connects the two sides of the framing. In this.
osition which is shewn in dotted lines, the empty roller can be readily removed
nd replaced by a full one.
This having been done the bars are easily raised again by turning the
ank handle.
When the arms have been brought back to the position shewn in full lines, they
e again secured by the thumb nuts 5.
In certain cases it is of advantage, for preventing smudging, to interpose a
eet of blotting paper between the coils of the printed sheet f when coiling it
on the roller d. For this purpose a roller q carrying a continuous sheet of
otting paper is mounted in bearings 8 which are fixed on the rear end of the
aming of the machine; the unwinding of the paper is controlled by a brake

page_text: for ensuring the regular coiling up thereof together with the printed sheet.
For ensuring the regularity of such coiling it is necessary that the roller q
should be at about the same level as the roller d and close to the latter, as
shewn on the drawing. The framing has been constructed to suit this arrange-
ment, as also for conveniently carrying the guide bars and rollers for the
continuous sheet f, as above described, and for facilitating access to the inking
apparatus. The frame being made so that access can be gained in front of
the inking apparatus for attending to this. For this purpose the framing has
been sufficiently increased in length between the inking apparatus arranged
at 10 and the supply roller at a so that a workman can stand in this part of
the machine, which has been left free for this purpose. The workmen gains
access to this space from the left hand side of the machine, a gap being left
on that side of the framing for this purpose between the dotted lines 11, 12
and the belt o being raised up sufficiently opposite this point by passing it
over guide rollers 13, 14.
The machine constructed as above described is suitable for printing in one
or more colours on paper or thin tissues. When printing on paper, this can
be led through the machine by itself in the manner described, but when printing
on thin tissues it is necessary to employ a web of strong paper for supporting
the tissue. It is necessary in this case that the sheet to be printed should
adhere effectually to the support and for this purpose we coat the side of the sup-
porting sheet that is to come in contact with the tissue, with wax, and when
the two are applied together we pass them between pressing rollers; it is essential
for this purpose that the wax be applied to the supporting sheet and not to
the tissue.
In order to ensure a reliable register for the printed sheet during its passage
through the machine, the sheet (or the supporting sheet in the case of thin
tissue) has holes formed at distances apart along its edges, as is usual, and
workmen situated on each side of the machine guide the sheet so that pins
provided on each side of the cylinder enter one or other of these holes, at each
revolution of the cylinder.
But owing to the shrinking and expansion of the paper in width due to
variations in its hygrometric condition, it is necessary to be able to vary to a
certain extent the distance apart of the pins on the opposite sides of the cylinder.
For this purpose the pins are mounted as shewn at Fig. 5 and 6. It will be
seen that the pin 44 is carried by a small slide 45 which can slide in a dovetailed
guiding groove 46 fixed to the pneumatic gripper g.
This guide groove has at its end an angle piece in which is rotatably mounted
a regulating screw, 48, that cannot shift longitudinally therein, but which
screws into a threaded hole in the slide 45, so that by turning the two screws 48
simultaneously in one direction or the other, the two opposite slides with their
pins can be adjusted nearer together or farther apart, as may be required.
If it were desired to regulate the position of the pins in the direction at right
angles to the length of the cylinder this might be readily effected by pro-
viding a second regulating screw operating at right angles to the first one.
The machine is provided at 15, with a table for receiving separate sheets
for use when the machine is employed for printing on detached sheets instead
of on continuous paper.

page_text: Improvements in Printing Machines for Printing on One Side only of
Continuous Paper or Tissue.
I, EMILE PREBAY, of 191, Rue de l'Université, 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:-
-
This invention relates to improvements in printing machines for printing on
one side only of continuous paper or tissue in which the paper to be printed
upon is maintained on the cylinder during the printing by means of a pneumatic
holding device.
The present improvements have for their object to simplify the construction
of such machines, to improve the action thereof, and to render them more accurate,
regular and faultless in working.
I will describe the said improvements with reference to the drawings accom-
panying my Provisional Specification, which shows a printing machine with
pneumatic grippers to which the said improvements are applied.
Fig. 1 shows a complete side elevation of the machine, Figs. 2 and 3 are
detail sectional views of the impression cylinder, Fig. 4 is a part plan view
of the arrangement for actuating the roller for supplying the continuous sheet
to be printed upon, and that for receiving the printed sheet, as also the roller
which supplies the blotting paper Fig. 5 is a part elevation of the impression
cylinder shewing the device for regulating one of the register pins. Fig. 6
shows a section on line A-A of Fig. 5; Fig. 7 shews the arrangement of the
driving pulley of the receiving roller.
In the machines of the kind indicated, as heretofore constructed, the impression
cylinder is provided with a single pneumatic gripper and the continuous sheet
to be printed upon is maintained applied to the cylinder by causing it after
leaving the cylinder to pass over a suitably arranged guide roller having a
drawing action.
This arrangement is defective in several respects, and in particular because
smudging is always to be feared, notwithstanding the provision of more or less
complicated mechanical devices for effecting the cleaning of the roller because
it is the freshly printed side of the sheet which passes over such roller.
According to this invention I obviate this inconvenience by doing away with
the said guiding and drawing roller, and I ensure the effective adhesion of
the sheet upon the cylinder by providing this with two pneumatic grippers, of
which one at least is in action, at any given moment.
always maintained upon the cylinder by at least one gripper, it cannot slip or
The sheet being thus
become displaced thereon, so that all difficulty as regards the registering is
avoided.
Fig. 1 shews clearly the path followed by the paper sheet to be printed upon,
as also the form given to the framing for obtaining in the simplest manner
he guiding of the sheet during its travel.
The continuous sheet f to be printed upon unrolls from the supply roller a,
asses over guide bars such as 16, 17, 18, 19, 20, and over the guide roller 21,
hence it passes round the impression cylinder o and thence to the receiving
oller d, in passing over guides such as e, 22, 23, 24, 25, fixed at the top of the
raming.
On the impression cylinder c the sheet is securely held by the suckers or
neumatic grippers 9, 28, Figs. 1 to 3, of which one at least is in action thereon

page_text: at any given moment. For this purpose a vacuum is produced in the suckers
when they are in the position 1, in order that they may attract the sheet f and
the exhaust is maintained until the sheet becomes detached at 2 in passing
tangentially away from the cylinder to the guide e. It will be observed that
while one of the suckers (g for example) passes from 1 to 2, the other, 28, passes
to 1 where it enters into action, so that this sucker will already have commenced
its action before the other ceases to hold the sheet, and the latter is consequently
always held by pneumatic action.
The exhaust is produced in the suckers as follows:
The shaft of the cylinder c is hollow at both ends, at j and at 29 Fig. 2,
and the suckers g, 28, are connected respectively to the channels and 29 by
tubes, 30, the said channels being in communication by the tubes 1, 31, with
an exhausted chamber. On the tubes 7, 31, are cocks m, 32, Fig. 1, which are
respectively actuated by cams », 33, fixed on the shaft which actuates the
carriage and inking apparatus.
The cam n is so formed and fixed that the cock m is opened immediately
before the platten commences its working stroke, the sucker being then at 1;
at the same time the bar his pressed down upon the sheet f so as to press this
upon the sucker, after which it is at once raised again; the cam n afterwards
closes the cock m as soon as, in consequence of the rotation of the cylinder c,
the sucker has passed the position 2, in which the sheet f has passed away
from it.
The cam 33 is so formed and fixed that it causes the cock 32 to open as soon
as the sucker 28 arrives at 1 during the rotation of the cylinder c, so that this
sucker holds the paper sheet without requiring the bar h to be applied thereto;
the cam 33 afterwards closes the cock 32 when the sucker 28 has arrived at 2.
It will be seen in Fig. 1, that the sheet f which unrolls from the roller a,
hangs free between this and the guide bar 16. It is indispensible that the
sheet should have some slack in order to have full liberty to place itself securely
on the cylinder c. In order, however, that it shall unroll correctly, it is necessary
to load it somewhat, by placing a small wooden roller b in the loop of the
hanging part.
In order that the slack of the sheet may be maintained during the printing
operation, it is indispensable that the speed of unrolling of the sheet shall
always be practically equal to the speed of rolling up on the roller d. For
obtaining this result, the relative speeds of the rollers d and a are controlled as
follows. The receiving roller is driven by a belt o, Figs. 1 and 7, which
is actuated through a pinion p, by one of the toothed rings 7 on the cylinder c
which serve for effecting its rotation by the forme carriage. The belt o is
suitably stretched by a weight r, it passes round a pulley 34 on the shaft of
the roller. When the receiving roller d has become wound to its full extent
with the continuous sheet it is necessary to replace it by an empty one; also
in order that the same pulley 34 may serve successively for all the receiving
rollers it is not mounted directly upon the axis 36 of the roller, but upon a
sleeve 35 that is slid on the left hand end of this axis, which is there formed
with a flat surface fitting a corresponding flat surface in the bore of the sleeve,
so that the axis carries the sleeve round with it.
As the belt o is driven with a constant speed while the roller has to be
rotated with a gradually decreasing speed in proportion as its diameter increases
by the winding on of the printed sheet, the pulley 34 is not fixed on the sleeve 35,
but is connected thereto by a friction clutch capable of regulation, whereby the
winding on of the sheet f can be effected at a tension that can be regulated
at will.
This friction clutch is shewn at Fig. 7. It will be seen that the sleeve 35,
has a circular collar 37, formed on it, and has a screw thread formed on part of
its length.
On this sleeve is slid first a leather washer 38, which bears against the collar,

page_text: then the pulley 34, then a leather washer 39, a loose metal collar 40, and a
strong helical spring 41, against which presses a wheel-nut 42, screwed upon
the end of the sleeve. A screw 43; which passes through the loose collar 40,
and takes into a groove 49 of the sleeve, allows the collar a certain amount of
play in the direction of the length of the sleeve, but obliges the latter to turn
with the collar.
In screwing the nut 42, upon the sleeve, the spring 41, is compressed, and
this consequently presses the collar 40 with greater or less force towards the
fixed collar 37 thus producing greater or less frictional adhesion between these
parts and the pulley-boss through the medium of the leather washers 38
and 39.
For regulating this adhesion and consequently the tension under which the
sheet is wound up on the roller, it suffices to turn the wheel-nut 42 more
or less in one direction or the other.
The receiving roller din its turn controls the feeding roller a, by means
of an endless cords Figs. 1 and 4 which passes over two grooved conical pullies, t
and fixed on the axes of the two rollers.
By this arrangement it is always easy to regulate at will the speed at which
the sheet is unrolled, as it only requires for this purpose to shift the cord s
from one groove to another of the two pulleys.
Fig. 4 shews this arrangement, as also an arrangement of regulating screws
for regulating the transverse positions of the rollers, so that the unrolling and
rolling up of the sheet may always take place correctly..
It will be seen that as the feed roller a is placed in the machine in a relatively
elevated position, the placing thereof may present some difficulty as this roller
is sometimes very heavy. For facilitating such placing I have arranged the
supports of the roller so that they may be lowered for placing thereon a filled
roller, after which they are raised into position by means of suitable toothed
gearing arranged so that this operation is easily effected.
This arrangement is shewn in Fig. 1. It will be seen that the bearings
that receive the axis of the roller a are formed on armis ac which are fixed upon
a shaft y mounted in the framing. This shaft can be rotated by a crank
handle z, to which it is connected by a train of toothed wheels 3, 4.
While the machine is at work the arms are fixed in their vertical position
by thumb nuts 5. When the roller a requires to be changed, these nuts are
removed and the arms are lowered until the bars 6 fixed thereto bear against
an abutment bar which connects the two sides of the framing. In this
position which is shewn in dotted lines, the empty roller can be rapidly removed
and replaced by a full one.
This having been done the bars are easily raised again by turning the
crank handle z.
When the arms & have been brought to the positon -shewn in full lines, they
are again secured by the thumb nuts 5.
In certain cases it is of advantage, for preventing smudging, to interpose a
sheet of blotting paper between the coils of the printed sheet f when coiling it
up on the roller d. For this purpose a roller y carrying a continuous sheet of
blotting paper is mounted in bearings 8 which are fixed on the rear end of the
framing of the machine; the unwinding of the paper is controlled by a brake
for ensuring the regular coiling up thereof together with the printed sheet.
For ensuring the regularity of such coiling it is necessary that the roller g
should be at about the same level as the roller d and close to the latter, as
shewn on the drawing. The framing has been constructed to suit this arrange-
ment, as also for conveniently carrying the guide bar bars and rollers for the
continuous sheet f, as above described, and for facilitating access to the inking
apparatus. The frame being made so that access can be gained in front of
the inking apparatus for attending to this. For this purpose the framing has
been sufficiently increased in length between the inking apparatus arranged

page_text: at 10 and the supply roller at a so that a workman can stand in this part of
the machine which has been left free for this purpose. The workman gains
access to this space from the left hand side of the machine, a gap being left
on that side of the framing for this purpose between the dotted lines 11, 12
and the belt o being raised up sufficiently opposite this point by passing it
over guide rollers 13, 14.
The machine constructed as above described is suitable for printing in one
or. more colours on paper or thin tissues. When printing on paper, this can
be led through the machine by itself in the manner described, but when printing
on thin tissues it is necessary to employ a web of strong paper for supporting
the tissue. It is necessary in this case that the sheet to be printed should
adhere effectually to the support and for this purpose, I coat the side of the sup-
porting sheet that is to come in contact with the tissue with wax, and when
the two are applied together I pass them between pressing rollers; it is essential
for this purpose that the wax be applied to the supporting sheet and not to
the tissue.
In order to ensure a reliable register for the printed sheet during its passage
through the machine, the sheet (or the supporting sheet in the case of thin
tissue) has holes formed at distances apart along its edges, as is usual, and
workmen situated on each side of the machine guide the sheet so that pins
provided on each side of the cylinder enter one or other of these holes, at each
revolution of the cylinder.
But owing to the shrinking and expansion of the paper in width due to
variations in its hygrometric condition, it is necessary to be able to vary to a
certain extent the distance apart of the pins on the opposite sides of the cylinder.
For this purpose the pins are mounted as shewn at Figs. 5 and 6. It will be
seen that the pin 44 is carried by a small slide 45 which can slide in a dovetailed
guiding groove 46 fixed to the pneumatic gripper g.
This guide groove has at its end an angle piece in which is rotatably mounted
a regulating screw, 48, that cannot shift longitudinally therein, but which
screws into a threaded hole in the slide 45, so that by turning the two screws 48
simultaneously in one direction or the other, the two opposite slides with their
pins can be adjusted nearer together or farther apart, as may be required.
If it were desired to regulate the position of the pins in the direction at right
angles to the length of the cylinder this might be readily effected by pro-
viding a second regulating screw operating at right angles to the first one.
The machine is provided at 15, with a table for receiving separate sheets
for use when the machine is employed for printing on detached sheets instead
of on a continuous web.
