Improvements in Printing Machines.
I, JULES MICHAUD, of 96, Rue d'Assas, Paris, France, Engineer, do hereby
declare the nature of this invention to be as follows;-
The arrangement of machine forming the object of the present invention, is
illustrated in the accompanying drawings, in which
Fig. 1 is a side elevation of such machine, and Fig. 2 a plan view showing the
cylinders, the apparatus for turning the paper, and the four printing formes.
The principal parts of the machine are:-
1st. The bed having a to and fro movement, which is imparted to it by a
pinion engaging a rack 3, as in ordinary reciprocating machines. This bed
may be actuated in any other suitable manner.
Upon the bed are arranged four formes corresponding to the four pages of the
paper to be printed; if it is a question of a journal the formes 4 and 5 are for
one side and 6 and 7 for the other.
2nd. The four cylinders 8, 9, 10, and 11.
The formes 4 and 6 pass beneath the cylinders 8 and 9; the formes 5 and 7
pass beneath the cylinders 10 and 11.
The four cylinders have a rising and falling movement such that they only fall
during the travel of the bed in the direction of the arrow, and they are raised
during its opposite travel. This rising and falling movement of the cylinders
may be obtained in various manners, such as by means of cams mounted on a
shaft 12 making one revolution for the double travel of the bed, such cams acting
by means of levers upon movable supports carrying the cylinders, in the manner
employed in machines which are called perfecting machines.
I reserve to myself the right of producing this rising movement in any other
suitable manner.
The printing cylinders 8, 9, 10, and 11 have a continuous rotary movement
always in the same direction, which is that indicated by the arrows upon the
drawing.
3rd. The inking apparatus 13 and 14.
4th. The turning or reversing apparatus 15.
5th. The cutter folders 16.
The continuous web of paper proceeding from the reel 17 after having passed
over feed rollers proceeds round the cylinder 11, and is partly printed by the
forme 5 passing under this cylinder.
The web continuing its travel then passes round the cylinder 10 and is again
printed on the forme 5, but in one of the portions which remained blank.
The web then proceeds round the cylinders 9 and 8 successively, and is printed
by the contact of these cylinders with the forme 4, these two latter impressions

page_text: being produced between those obtained by means of the forme 5 and the cylinders 10
and 11. The travel of the web between the cylinders 11, 10, 9, 8, is calculated
so that on its leaving the last cylinder it will be found to be printed on one
side in a continuous manner, with only the space corresponding to the margins
between the pages.
So as to ensure an exact travel of the paper the rollers 18, 19, 20, 21, 22, 23,
are either partially or wholly movable, so as to cause each impression to occupy
exactly the position which it should have with regard to the others.
I may if desired cause the two different impressions 4 and 5 to be produced one
upon the other, and by employing on the inking apparatuses 13 and 14 different
coloured inks produce an impression of two superposed colours. In order to pro-
duce this result it is only necessary to correspondingly regulate the travel of
the web.
The web on leaving the cylinder 8 passes over the rollers 24, 25, 26, then to
the turning or reversing apparatus 15, upon which it is displaced parallel to itself;
it returns round the cylinder 11 after passing over the rollers 27 and 28, but in
a position adjacent to that which it previously occupied, and turned over so as
to present to the formes or cliches 7 and 6 its unprinted portion.
The web thus displaced and turned over again resumes its travel from the
cylinder 11 to the cylinder 8, and receives on the opposite side four new impres-
sions, two obtained from the forme 7, which are situated between two obtained
from the forme 6.
The web completely printed on both sides leaves the cylinder 8, and then pro-
ceeds between the cylinders 16, which cut it to the desired size and give to the
sheet a first fold if this is required, and direct it to the other portions of the folder,
if the machine is provided with same. Or the cut sheets may be accumulated
and delivered mechanically by means of a flyer, as is effected on rotary printing
machines.
The machine as I have described it, during a double travel of the bed prints
two identical copies; these copies are separated and folded after printing as has
been described; but in this arrangement the machine prints only a single size
of paper, in the direction of the development of the cylinders, the size being equal
to double the development of these cylinders.
In Fig. 3 I show the arrangement of the machine which is employed for printing
sheets of variable dimensions in the direction of the development of the cylinders.
The paper proceeding from the reel 17 is carried forward by the rollers 28 and 29
at a speed varying with the size to be produced; it is cut to the required size
between the cylinders 30 and 31, the cylinder 31 making one revolution for two
of the printing cylinders.
The separated sheets are carried forward by a cylinder 32, which may be pro- 4
vided with grippers; they descend between tapes and arrive at cylinder 11.
The sheets then follow the same course as that of the continuous web in the
machine previously described, but they effect the travel between tapes. They are
turned over on the turning or reversing apparatus. Like the continuous web
they are printed on the other side under the same conditions, then they are con- 4
ducted, again between tapes, to the folding cylinders or to the accumulator.
The first sheet engaged in the machine is printed on the forme 5 while passing
round cylinder 11, and on forme 4 while passing round the cylinder 9. The
second sheet will receive the same impressions, but while passing round the
cylinders 10 and 8. It is the same for the impression on the opposite side.
The only regulation to be made when the size of the sheet is varied, consists in
increasing or diminishing the travel between the cylinders 10 and 9, which will
be effected by the movability of the rollers 20 and 21.

page_text: 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 machine forming the object of the present invention, is illustrated in the
drawings (Figs. 1 to 3) accompanying the Provisional Specification, in which
Fig. 1 is a side elevation of one form of the machine, and Fig. 2 a plan view
showing the cylinders, the apparatus for turning the paper, and the four printing
formes.
The principal parts of the machine are:-
1st. The bed 1 having a to and fro movement, which is imparted to it by a
pinion 2 engaging a rack 3, as in ordinary reciprocating machines. This bed
may be actuated in any other suitable manner.
Upon the bed are arranged four formes corresponding to the four pages of the
paper to be printed; if it is a question of a journal the formes 4 and 5 are for
one side and 6 and 7 for the other.
2nd. The four cylinders 8, 9, 10, and 11.
The formes 4 and 6 pass beneath the cylinders 8 and 9; the formes 5 and 7
pass beneath the cylinders 10 and 11.
The four cylinders have a rising and falling movement such that they only fall
during the travel of the bed in the direction of the arrow, and they are raised
during its opposite travel. This rising and falling movement of the cylinders
may be obtained in various manners, such as by means of cams mounted on a
shaft 12 making one revolution for the double travel of the bed, such cams acting
by means of levers upon movable supports carrying the cylinders, in the manner
employed in machines which are called perfecting machines.
I reserve to myself the right of producing this rising movement in any other
suitable manner.
The printing cylinders 8, 9, 10, and 11 have a continuous rotary movement
always in the same direction, which is that indicated by the arrows upon the
drawing.
3rd. The inking apparatus 13 and 14.
4th. The turning or reversing apparatus 15.
5th. The cutter folders 16.
The continuous web of paper proceeding from the reel 17 after having passed
over feed rollers proceeds round the cylinder 11, and is partly printed by the
forme 5 passing under this cylinder.
The web continuing its travel then passes round the cylinder 10 and is again
printed on the forme 5, but in one of the portions which remained blank.
:
The web-then proceeds round the cylinders 9 and 8 successively, and is printed
by the contact of these cylinders with the forme 4, these two latter impressions
being produced between those obtained by means of the forme 5 and the cylinders 10
and 11. The travel of the web between the cylinders 11, 10, 9, 8, is calculated
so that on its leaving the last cylinder it will be found to be printed on. one
side in a continuous manner, with only the space corresponding to the margins
between the pages.
So as to ensure an exact travel of the paper the rollers 18, 19, 20, 21, 22, 23,
are either partially or wholly movable, so as to cause each impression to occupy
exactly the position which it should have with regard to the others,

page_text: may
if desired cause two different impressions 4 and 5 to be produced one
upon the other, and by employing on the inking apparatuses 13 and 14 different
coloured inks produce an impression of two superposed colours. In order to pro-
duce this result it is only necessary to correspondingly regulate the travel of
the web.
The web on leaving the cylinder passes over the. rollers 24, 25, 26, then to
the turning or reversing apparatus 15, upon which it is displaced parallel to itself;
it returns round the cylinder 11 after passing over the rollers 27 and 28, but in
a position adjacent to that which it previously occupied, and turned over so as
to present to the formes or cliches 7 and 6 its unprinted portion.
The web thus displaced and turned over again resumes its travel from the
cylinder 11 to the cylinder 8, and receives on the opposite side four new impres-
sions, two obtained from the forme 7, which are situated between two obtained
from the forme 6.
The web completely printed on both sides leaves the cylinder S, and then pro-
ceeds between the cylinders 16, which cut it to the desired size and give to the
sheet a first fold if this is required, and direct it to the other portions of the folder,
if the machine is provided with same. Or the cut sheets may be accumulated
and delivered mechanically by means of a flyer, as is effected on rotary printing
machines.
The machine as I have described it, during a double travel of the bed prints
two identical copies; these copies are separated and folded after printing as has
been described; but in this arrangement the machine prints only a single size
of paper, in the direction of the development of the cylinders, the size being equal
to double the development of these cylinders.
In Fig. 3 I show an arrangement of the machine which is employed for printing
sheets of variable dimensions in the direction of the development of the cylinders.
The paper proceeding from the reel 17 is carried forward by the rollers 28 and 29
at a speed varying with the size to be produced; it is cut to the required size
between the cylinders 30 and 31, the cylinder 31 making one revolution for two
of the printing cylinders.
The separated sheets are carried forward by a cylinder 32, which may be pro-
vided with grippers; they descend between tapes and arrive at cylinder 11.
The sheets then follow the same course as that of the continuous web in the
machine previously described, but they affect the travel between tapes. They are
turned over on the turning or reversing apparatus. Like the continuous web
they are printed on the other side under the same conditions, then they are con-
ducted, again between tapes, to the folding cylinders or to the accumulator.
The first sheet engaged in the machine is printed on the forme 5 while passing
round cylinder 11, and on forme 4 while passing round the cylinder 9. The
second sheet will receive the same impressions, but while passing round the
cylinders 10 and 8. It is the same for the impression on the opposite side. The
only regulation to be made when the size of the sheet is varied, consists in
increasing or diminishing the travel between the cylinders 10 and 9, which will
be effected by the movability of the rollers 20 and 21.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The combination of cylinders with a continuous movement printing upon
flat formes with a turning or reversing apparatus for the paper, so as to obtain
on a continuous web impressions on the opposite sides of this web by means of
the same cylinders upon different formes.
2. The combination of the apparatus printing on flat formes, and of turning or
reversing apparatus with a cutting and folding apparatus forming a continuation
of same.
3. The combination of the apparatus printing on flat formes and of the turning

page_text: or reversing apparatus with a cutting apparatus, accumulating the cut sheets
and a mechanical delivery apparatus for unfolded sheets.
4. The combination of an apparatus supplying from a continuous web sheets
the size of which may be varied, with the printing apparatus and the reversing
or turning apparatus described.
5. The combination of the apparatus supplying sheets from a continuous web
with the printing apparatus and the reversing or turning apparatus described,
and also with a folder.
6. The combination of the apparatus supplying sheets from a continuous web
with the printing apparatus and the reversing or turning apparatus, and a
mechanical delivery apparatus for unfolded sheets.
