1, JULES MICHAUD, of 96 Rue d'Assas, Paris, France, Engineer, do hereby
declare the nature of this invention to be as follows:-
In the Specification of my prior Patent No. 1635 A.D. 1890, I have described
an improved rotary printing machine constructed for cutting and printing sheets of
varying dimensions.
The present Application relates to improvements in various parts of such machine
and in means for enabling a continuous off-set web of paper to be adapted
thereto.
In the arrangement illustrated in Fig. 1 Sheet 1 of the accompanying drawings,
the sheets to be printed arrive between the tapes 11 and 12, and are seized by the
cylinder 13 and printed by contact with the cylinder 14.
The grippers 50 of cylinder 13 are, as shown at 50, thrown back before
passing in front of cylinder 15, this being effected by the action of a cam such as is
employed in existing printing machines for obtaining such movement.
This throwing back has for its object to release the sheet and not to produce the
opening of the grippers in front of the cylinder 15, which cannot be effected, as the
continuous off-set web surrounds this cylinder.
The off-set proceeding from reel 51, after passing over the rollers 52, 52¹, 52",
passes right round the cylinder 15, then round part of cylinder 19, and passing
back over the rods 53, 53, 53, is rewound at 64 by the meaus already employed.
When employ a continuous off-set web, the movements of the grippers of
cylinders 15 and 19 are abolished and such grippers remain in continual contact
with their cylinders without holding the sheets, so as not to touch the off-set. For
this purpose it suffices either to abolish the cams which actuate the grippers, or to
remove the rollers upon which the cams act.
Under these conditions in order to effect the transfer of the sheet from cylinder 13
to cylinder 15, then, after the second impression, from cylinder 15 to cylinder 19,
I make use of tapes passing in the margins or blanks between the printed
portions.
thus have tapes which, starting from roller 54, pass over rods 55, cylinder 13,
cylinder 15, cylinder 19, cylinder 20, rods 56, 57, 58, 59, 60, 61, and return to
roller 54. The tapes will only pass in the manner described in the case where
the accumulation of the sheets occurs on the cylinder 19; in the case where
this occurs on cylinder 20, the tapes after passing round cylinder 19 will return by
the rods 53, 53, 57, 58, etc., without passing over cylinder 20.
Another set of tapes also passing in the blanks, passes over cylinders 13 and 15,
then over the rods 62 and 63 and returns to cylinder 13; other tapes passing over
the rods 65, 66, 67, apply the sheets to cylinder 19 when the accumulation is to be
effected on this cylinder.
In the case where the accumulation is to be effected on cylinder 20, I shall
employ tapes which, after passing round the cylinders 13, 15, 19, will return from
the latter to the rod 63, then to cylinder 13.
To prevent slipping of the sheets and to obtain a perfect superposition of the
sheets on cylinder 19, when it serves as an accumulator, I may provide this
cylinder with fixed or movable points which pierce the head of the sheet and will
ensure their regular travel. I may also apply the same fixed or movable points,

page_text: such as hereafter describe, on the cylinder 20 when I employ this cylinder as an
accumulator.
To facilitate access to the printing cylinder 14 and so as to provide space for the
off-set reel as well as the rewinding apparatus, I remove the frames carrying the
flyer shaft and the delivery table, from the frames of the machine, so as to leave a
passage between them.
The operation of the grippers of cylinder 20, whether it acts as an accumu-
lator or as a delivery cylinder, is retained. I may abolish the accumulation of
the sheets and lead them one by one either by the aid, of flyers, or by tapes,
to a folder operating either by means of cylinders, or by ordinary folding
appliances.
In Sheet 2 have shown an arrangement of machine in which the blanket
cylinders may either be provided or not with grippers, and in which the sheets
after printing are engaged in tapes which conduct them to folding or to delivery
mechanism.
The sheets arrive between the tapes 78 and engage the cylinder 70, are printed
by contact with cylinder 71, pass over cylinder 72, are printed by contact with
cylinder 73, and then engage between the tapes 74 and 75, which lead them either
to the folding cylinders 76 and 77, or to any other form of følder, or to an
accumulator.
At 96 is an off-set weh which after passing over cylinder 72 is rewound at 79.
To ensure the passage of the eheets from one cylinder to the other, then between
the delivery tapes 74 and 75, I make use of sets of tapes which pass in the blanks
of the impression in the following manner:
A first set pass over rod 80, the cylinder 70, the rods 81, 82, 83, and
return to 50.
The second set pass over rol 84, the cylinders 70 and 72, the rods 85, 86, 87, 88.
and return to 84.
I have invented various modifications in the machine shown in Sheet 1, which
while permitting the employment of the continuous off-set web will only necessitate
the abolition or rendering stationary of the grippers of the second blanket cylinder
while retaining those of the other cylinders.
In this arrangement which is shown in Fig. 3, Sheet 3, the sheets seized by the
first anket cylinder, are transmitted by the tapes 13 and 14 to the second
blanket cylinder 15, when a certain number of these sheets accumulate on the
cylimler 16, and the packet thus formed, seized by the grippers of cylinder 17, is
carried forward in front of the Ryers 18, which deposit them on table 19.
A continous off-set web proceeding from reel 51 protects the cylinder 15 from
becoming soiled, and then returns and is rewound at 64.
I have above stated that the cylinder 16 is an accumulating cylinder:
provided with grippers 22 which seize the sheet from cylinder 15.
is
In order that the off-set web which passes round cylinder 15 may not be forn by
the action of grippers 22, I may form this cylinder with a flat surface, or a gap 23,
so that at this part the off-set web is no longer in the form of a cylinder. In the
section of machine shown in Fig. 3, Sheet 3, it is represented as a chord of a circle
formed by the exterior of the cylinder 15. The cam 24 which governs the opening
of the grippers 22 is arranged so that the extremity of the latter in their closing
inovenient describe a line very close to the chord 23 formed by the off-set web, but
not touching such web. On the other hand the head of the sheet which does not
form part of the off-set web not only is not applied to the latter, but further tends
to move away from it.
By this means at the moment when the closing of the grippers terminates, their
extremity as shown in Fig. 3 is situated between the off-set web and the head of
the sheet, so that the grippers in closing apply the latter to the cylinder 16 without
having damaged the ill-set web.
This arrangement of the cylinder 15 has further the great advantage of
permitting the abolition of the folding back of the grippers 12, which grippers ou

page_text: account of the flat surface or gap in the cylinder 15 hold the sheet until the
moment when it should pass to the cylinder 15, which avoids all retardation of the
sheet.
I may employ the gap 23 of the cylinder 15 for arranging grippers therein, so as
to be able with these grippers to take the sheets from the cylinder 6 when the
machine operates without an off-set web.
In order to ensure the carrying forward of separate sheets on the cylinders
I may employ the arrangement shown in Sheets 4 and 5.
Fig. 5, Sheet 4. illustrates part of the machine represented in Sheet 1. The
sheets seized by the cylinder 13, released by the grippers 50, are detached from
the cylinder 13 by the tapes passing round this cylinder, then round the cylinder 16
and the rods 62 and 63.
In order to better ensure the carrying forward of the sheets on the cylinder 15,
I have thought of placing on this cylinder points such as a which pierce holes in
the margin of the head of the sheets. These points may either be fixed or
movable, in which latter case they are actuated by a cam through the inter-
mediary of levers, so as only to project for piercing the sheet, first passing through
the continuous off-set web and only to leave same when the sheet is to pass to the
cylinder 19. I may on the cylinder 15 arrange two or a greater number of these
points.
Upon cylinder 19 shall also employ points c fixed or movable, if this is
necessary to ensure the carrying forward and the perfect superposition of the
sheets. I may also arrange such points on the cylinder 20 when the sheets are
accumulated on this cylinder.
To ensure the separation of the sheet and the off-set web on the cylinder 19
without having to employ the tapes indicated above, I have thought of placing at d
on a rod, a brush or even a series of brushes corresponding to the blanks of the
impression. These brushes rubbing against the roller 53 and revolving in the
direction indicated by the arrow, have for their object to prevent the sheet from
following the off-set web and to maintain it applied to the cylinder 19. I further
reserve to myself the right of constructing the cylinder 19 as I have shown in
section in Fig. 6 Sheet 4, that is to say with an edge pierced with holes, these
holes being prolonged by tubes up to the hollow axle of the cylinder so as to be
able by the aid of a pump to produce at a suitable moment an air suction which
will properly apply the sheet to the cylinder 19, and which then ceasing will
permit it to be delivered to the cylinder 20. I may employ any other arrangement
for producing an air suction for maintaining the sheet on the cylinder 19 for the
desired time.
Fig. 7 Sheet 5 shows the same part of the machine and another arrangement for
producing the same result.
Beneath the cylinder 13 which seizes the head of the sheet by means of grippers,
I arrange a cylinder provided with a projecting piece g which slightly bends the
head of the sheet and presses it against the part of cylinder 13 at the moment
when the grippers are applied to this part; this arrangement has for its object to
permit the grippers 50 to turn while resting inside the circle of the cylinder.
Behind the part is a blade i which actuated by a cam j projects from the
cylinder pushing before it the head of the sheet at the moment when the latter is
to be transmitted to the cylinder 15.
This projection of the blade i causes the off-set web to be deflected onto
cylinder 15; at this moment the blade K situated at the interior of this cylinder,
being under the action of the cam m caused to bear on the off-set web, forms in the
latter fold or pleat in the interior of which is enclosed the head of the sheet,
which is thus carried forward and maintained on the cylinder 15 without the aid of
tapes; the cam m afterwards causes the blade K to withdraw when the sheet and
the off-set web are to be applied to the cylinder 19.
So that the fold or pleat made in the off-set web may be produced without
causing the latter to break, I may impart a movement to the roller 52", so as to

page_text: cause it to occupy the position indicated in dotted lines, at the moment when the
blade i operates.
I may also cause the blade K to turn so that when it is in the
position removed from engagement, it projects from the cylinder, as indiented at K'
in dotted lines.
The lifting of the off-set web produced by this means will permit of the paper
necessary for the formation of the fold being provided at the moment of the
closing of the blade K without causing an abrupt pull on the off-set web under the
action of the blade i.
The present invention relates to a further improvement having for its object to
avoid variations of margin by ensuring that always the same amount of paper will
be under the grippers of the first blanket cylinder when the sheets are seized by the
latter.
For this purpose the paper feed rollers 1 and 2 Fig. 3, Sheet. 3, and the cutting
cylinders 3 and 4 are mounted on frames which are capable of being moved towards
or away from the printing machine properly so called, so that the distance A
between the axis of the cutting cylinder and the axis of blanket cylimler 6, shall
always be substantially equal to the size of the sheet to be printed no matter what
such size may be.
In effecting this result the frames 5 can slide on the lase 7 of the machine, two
screws 8 fixed to this base passing through two nuts 9 fixed to each of the
frames.
A shaft 10 carrying two bevel pinions and which may be actuated by a crank 11
acts simultaneously on the two frames; according to whether the crank 11 is turned
in one direction or the other, the frames and the eating cylinders which they carry,
will approach to or recede from the blanket cylinder 6.
By this means the seizing of the sheets by the gripper 12 of the
cy linder 6 can
always be effected at the moment when the cut is effected, no matter what the size
of the sheets may be.
I may as shown in Fig. 4, Sheet 3, place between the cutters 3 and 4 and the
blanket cylinder 6, a cylinder 20 mounted in movable supports and of which the
distance between it and the cutting cylinder may be varied so that the seizing of
the sheets by the grippers 21 of this cylinder will always occur at the moment of
cutting, no matter what their size. The sheets thus separated will then proceed to
the cylinder 6 between two sets of tapes; I may further vary the position of the
cutting cylinders independently of the frames carrying same, either by displacing
them on these frames, or by any other means.

Improved Rotary Printing 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:-
In the Specification of my prior Patent No. 1635 A.D. 1890, I have described
an improved rotary printing machine constructed for cutting and printing sheets of
varying dimension.
The present Application relates to improvements in various parts of such machine
and in means for enabling a continuous off-set web of paper to be adapted
thereto.
In the arrangement illustrated in Fig. 1 Sheet 1 of the drawings filed with the
Provisional Specification the sheets to be printed arrive between the tapes II

page_text: and 12, and are seized by Le cymmer

and printed by CONTACT
LITC
cylinder 14.
The grippers 50 of the cylinder 13 are, as is shown at 50, thrown back before
passing in front of cylinder 15, this being effected by the action of a cam such as is
employed in existing printing machines for obtaining such movement.
This throwing back has for its object to release the sheet and not to produce the
opening of the grippers in front of the cylinder 15, which cannot be effected, as the
continuous off-set web surrounds this cylinder.
The off-set proceeding from reel 51, after passing over the rollers 52, 52, 5211,
passes right round the cylinder 15, then round part of cylinder 19, and passing back
over the rods 53, 53, 53, is rewound at 64 by the means already employed.
When employ a continuous off-set web, the movements of the grippers of
cylinders 15 and 19 are abolished and such grippers' remain in continual contact
with their cylinders without holding the sheets, so as not to touch the off-set. For
this purpose it suffices either to abolish the cams which actuate the grippers, or to
remove the rollers upon which the cams act.
Under these conditions in order to effect the transfer of the sheet from
cylinder 13 to cylinder 15, then, after the second impression, from cylinder 15 to
cylinder 19, make use of tapes passing in the margins or blanks between the
printed portions.
I thus have tapes which, starting from roller 54, pass over rods 55, cylinder 13,
cylinder 15, cylinder 19, cylinder 20. rods 56, 57, 58, 59, 60, 61, and return to
roller 54. The tapes will only pass in the manner described in the case where the
accumulation of the sheets occurs on the cylinder 19; in the case where this occurs
on cylinder 20, the tapes after passing round cylinder 19 will return by the
rods 53, 53', 57, 58 etc., without passing over cylinder 20.
Another set of tapes also passing in the blanks, passes over cylinders 13 and 15
then over the rods 62 and 63 and returns to cylinder 13; other tapes passing over
the rods 65, 66, 67, apply the sheets to cylinder 19 when the accumulation is to be
effected on this cylinder.
In the case where the accumulation is to be effected on cylinder 20, I shall
employ tapes which, after passing round the cylinders 13, 15, 19, will return from
the latter to the rod 63 then to cylinder 13.
To prevent slipping of the sheets and to obtain a perfect superposition of the
sheets on cylinder 19, when it serves as an accumulator, I may provide this
cylinder with fixed or movable points which pierce the head of the sheet and will
ensure their regular travel. may also apply the same fixed or movable points,
such as hereafter describe, on the cylinder 20 when I employ this cylinder as an
accumulator.
To facilitate access to the printing cylinder 14 and so as to provide space for the
off-set reel as well as the re-winding apparatus, 1 remove the frames carrying the
flyer shaft and the delivery table, from the frames of the machine, so as to leave a
passage between thein.
The operation of the grippers of cylinder 20, whether it acts as an accumulator
or as a delivery cylinder, is retained. I may abolish the accumulation of the
sheets and lead them one by one either by the aid of flyers or by tapes, to a
folder operating either by means of cylinders, or by ordinary folding appliances.
In Sheet 21 have shown an arrangement of machine in which the blanket
cylinders may either be provided or not with grippers, and in which the sheets after
printing are engaged in tapes which conduct them to folding or to delivery
mechanism.
The sheets arrive between the tapes 78 and engage the cylinder 70, are printed
by contact with cylinder 71, pass over cylinder 72, are printed by contact with
cylinder 73, and then engage between the tapes 74 and 75, which lead them either
to the folding cylinders 76 and 77 or to any other form of folder, or to an
accumulator.
At 98 is an off-set web which after passing over cylinder 72 is rewound at 79.

page_text: the delivery tapes 74 and 75, I make use of sets of tapes which pass in the blanks
of the impression in the following manner:
A first set pass over rod 80, the cylinder 70, the rods 81, 82, 83, and return
to 80.
The second set pass over rod 84, the cylinders 70 and 72, the rods 85, 86, 87, 58,
and return to 84.
I have invented various modifications in the machine shown in Sheet 1, which
while permitting the employment of the continuong off-set web will only necessitate
the abolition or rendering stationary of the grippers of the second blanket cylinder
while retaining those of the other cylinders.
In this arrangement which is shown in Fig. 3, Sheet 3, the sheets seized by the
first blanket cylinder, are transmitted by the tapes 13 and 14 to the second blanket
cylinder 15, when a certain number of these sheets accumulate on the cylinder 16,
and the packet this formed, seized by the grippers of cylinder 17, is carried
forward in front of the flyers 18, which deposit them on table 19.
A continous off-set web proceeding from reel 51 protects the cylinder 15 from
becoming soiled, and then returns and is rewound at 64.
I have above stated that the cylinder 16 is an accumulating cylinder; it is
provided with grippers 22 which seize the sheet from cylinder 15,
In order that the off-set web which passes round cylinder 15 may not be torn by
the action of grippers 22, I may form this cylinder with a flat surface, or a gap 23,
so that at this part the off-set wel is no longer in the form of a cylinder. In the
section of machine shown in Fig. 3, Sheet 3, it is represented as a chord of a circle
formed by the exterior of the cylinder 15. The cam 24 which governs the opening
of the grippers 22 is arranged so that the extremity of the latter in their closing
movement describe a line very close to the chord 23 formel by the off-set web, but
not touching such web. On the other hand the head of the sheet which does not
form part of the off-set web not only is not applied to the latter, but further tends
to move away from it.
By this means at the moment when the closing of the grippers terminates, their
extremity as shown in Fig. 3 is situated between the off-set web and the head of
the sheet, so that the grippers in closing apply the latter to the cylinder 16 without
having damaged the off-set web.
This arrangement of the cylinder 15 has further the great advantage of per-
mitting the abolition of the folding back of the grippers 12, which grippers on
account of the flat surface or gap in the cylinder 15, hold the sheet until the
moment when it should pass to the cylinder 15, which avoids all retardation of the
sheet.
I may employ the E*]! 23 of the cylinder 15 for arranging grippers therein, so as
to be able with these grippers to take the sheets from the cylinder 6 when the
machine operates without an off-set web.
In order to ensure the carrying forward of separate sheets on the cylinders I may
employ the arrangement shown in Sheets 4 and 5.
Fig. 5, Sheet 4, illustrates part of the machine represented in Sheet 1. The
sheets seized by the cylinder 13, released by the grippers 50, are detached from the
cylinder 13 by the tapes passing round this cylinder, then round the cylinder 16
and the rods 62 and 63.
In order to better ensure the carrying forward of the sheets on the cylinder 15,
I have thought of placing on this cylinder points such as a which pierce holes in
the margin of the head of the sheets. These points may either be fixed or movable,
in which latter case they are actuated by a cam through the intermediary of
levers, so as only to project for piercing the sheet, first passing through the
continuous off-set web and only to leave same when the sheet is to pass to the
cylinder 19. 1 may on the cylinder 15 arrange two or a greater number of these
points.
Upon cylinder 19 1 shall also employ points fixed or movable, if this is

page_text: necessary to ensure the carrying forward and the perfect superposition of the sheets.
1 may also arrange such points on the cylinder 20 when the sheets are accumulated
on this cylinder.
To ensure the separation of the sheet and the off-set web on the cylinder 19
without having to employ the tapes indicated above, I have thought of placing
at d on a rod, a brush or even a series of brushes corresponding to the blanks of the
impression. These brushes rubbing against the roller 53 and revolving in the
direction indicated by the arrow, have for their object to prevent the sheet from
following the off-set web and to maintain it applied to the cylinder 19. further
reserve to myself the right of constructing the cylinder 19 as I have shown in
section in Fig. 6 Sheet 4, that is to say with an edge pierced with holes, these holes
being prolonged by tubes up to the hollow axle of the cylinder so as to be able by
the aid of a pump to produce at a suitable moment an air suction which will
properly apply the sheet to the cylinder 19, and which then ceasing will permit it
to be delivered to the cylinder 20. I may employ any other arrangement for
producing an air suction for maintaining the sheet on the cylinder 19 for the
desired time.
Fig. 7 Sheet 5 shows the same part of the machine and another arrangement for
producing the same result.
Beneath the cylinder 13 which seizes the head of the sheet by means of grippers,
I arrange a cylinder provided with a projecting piece g which slightly bends the
head of the sheet and presses it against the part of cylinder 13 at the moment
when the grippers are applied to this part; this arrangement has for its object to
permit the grippers 50 to turn while resting inside the circle of the cylinder.
Behind the part is a blade which actuated by a cam j projects from the
cylinder pushing before it the head of the sheet at the moment when the latter is to
be transmitted to the cylinder 15.
This projection of the blade causes the off-set web to be deflected on to
cylinder 15, at this moment the blade K situated at the interior of this cylinder
being under the action of the cam m caused to bear on the off-set web, forms in the
latter a fold or plent, in the interior of which enclosed the head of the sheet,
which is thus carried forward and maintained on the cylinder 15 without the aid of
tapes the cam m afterwards causes the blade K to withdraw when the sheet and
the off-set web are to be applied to the cylinder 19.
So that the fold or pleat made in the off-set web may be produced without
causing the latter to break, I may impart a movement to the roller 5211, 50 as to
cause it to occupy the position indicated in dotted lines at the moment when the
blade operates. may
also cause the blade K to turn so that when it is in the
position removed from engagement, it projects from the cylinder, as indicated at K'
in dotted lines.
The lifting of the off-set web produced by this means will permit of the paper
necessary for the formation of the fold being provided at the moment of the
closing of the blade K without causing an abrupt pull on the off-set web under
the action of the blade i.
The present invention relates to a further improvement having for its object to
avoid variations of margin by ensuring that always the same amount of paper will
be under the grippers of the first blanket cylinder when the sheets are seized by
the latter.
For this purpose the paper feed rollers 1 and 2 Fig. 3, Sheet 3, and the cutting
cylinders 3 and 4 are mounted on frames which are capable of being moved
towards or away from the printing machine properly so called, so that the
distance A between the axis of the cutting cylinder and the axis of blanket
cylinder 6, shall always be substantially equal to the size of the sheet to be printed
no matter what such size may be.
To effecting this result the frames à can slide on the base 7 of the inachine, two
screws 8 fixed to this base passing through two nuts 9 fixed to each of the frames.
A shaft 10 carrying two bevel pinions and which may be actuated by a crank II

page_text: acts simultaneously on the two frames: according to whether the crank II IS
turned in one direction or the other, the frames and the cutting cylinders which
they carry will approach to or recede from the blanket cylinder 6.
By this means the seizing of the sheets by the gripper 12 of the cylintor 6 can
always be effected at the moment when the cut is effected, no matter what the size
of the sheets may be.
1 may as shown in Fig. 4, Sheet 3, place between the cutters 3 and 4 and the
blanket cylinder 6, a cylinder 20 mounted in movable supports and of which the
distance between it and the entting cylinder may be varied so that the seizing
of the sheets by the grippers 21 of this cylinder will always occur at the moment
of cutting, no matter what their size. The sheets thus separated will then
proceed to the cylinder 6 between two sets of tapes; I may further vary the
position of the cutting cylinders independently of the frames carrying same,
either by displacing them on these frames, or by any other means.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, declare that what I
claim is :-
In all-size rotary printing machines
1. The combination of a first blanket cylinder provided with grippers for seizing
the sheets to be printed, with a continuous off-set web for enveloping the second
aylinder, and of two sets of tapes for ensuring the transfer from one cylinder to the
other, and the delivery of the printed sheets.
2. The combination of a continuous off-set web with a blanket cylinder the
grippers of which are thrown back or disappear within the cylinder so as to escape
the continuous off-set web.
3. The combination of a continuous off-set web with tapes serving to ensure the
transfer of the sheets to be printed from one cylinder to the other, and their
delivery between two sets of tapes, the i opression cylinders of the machine not
being provided with grippers.
4. The arrangements of tapes described in combination with the continuous off-set
web and the delivery cylinder for the printed sheets.
5. The arrangement of points in combination with accumulating cylinders, for
ensuring the perfect superposition of the sheets.
6. The arrangements described and shown in Sheets 1 and of the drawings, of
machines to which the different improvements described are applied.
7. The employment of a blanket cylinder round which passes a continuous off-set
web, such cylinder having a flat surface or gap, in combination with the grippers of
a first. blanket cylinder for enabling the sheets to be held by the grippers on the
first cylinder until they pass to the second blanket cylinder round which the off-set
web passes, without cansing the grippers to hear against such off-set web.
8. The employment of a blanket cylinder over which passes a continuous off-set
web, and having a flat surface or gap, in combination with an accumulating or
delivery cylinder the movement of the grippers of which is regulated so that they
seize the sheets without bearing against the off-set web.
9. The arrangements described which on a machine in which the transfer of the
sheets is effected by grippers, for the printing and for the delivery, permit the
grippers of a single cylinder only-the blanket cylinder for the second impression-
being rendered immovable so as to employ a continuous off-set web.
10. The combination with the continuous off-set web surrounding the second
impression cylinder, of the tapes and points, either movable or not, mounted on this
cylinder so as to better fix the sheet thereon.
11. The employment of brushes for producing the separation of the printed sheets
from the continuous off-set web.
12. The combination of the brushes described in the preceding claim with points
fixed to the delivery or accumulating cylinder of the sheets, for better holding the
sheets thereon.

page_text: 13. The employment of a delivery cylinder for sheets provided with a suction
apparatus capable of fixing the sheets thereto, in combination with a continuous
off-set web from which it is necessary to detach them.
14. The combination with the continuous off-set web, of folding blades producing
in the web a fold and at the same time inserting therein the head of the sheets to
be printed.
15. The combination with the arrangement described in the preceding claim, of
