Improvements in Web Printing Machines.
I, HENRY EDWARD NEWTON, of the Office for Patents, 6, Bream's Buildings,
Chancery Lane, in the County of Middlesex, Patent Agent, 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 web printing machines, its objects being to provide a
machine of this class in which the number of parts shall be reduced to a minimum,
and which shall be more simple and compact, and require less adjustment, than
those heretofore in use.
A further object is to provide an improved means for adjusting the position of
the web turner used in certain well-known classes of web printing machines.
With these objects in view, the invention consists generally in combining with the
printing cylinders of a web-printing machine, a web turner and a pair of perforating
or cutting rolls, one or both of the axes of which are in line with, and preferably
carried by the shafts of the printing cylinders, and in various constructions and
combinations of parts, all of which will be more particularly described in the
Specification and pointed out in the claims.
While the features constituting the present invention, are of general application
in web printing machines, they are especially designed for small machines used in
printing circulars, bills, and small papers of all kinds, for which a light, simple,
and cheap machine is especially desirable.
For a full understanding of the invention, a detailed description of a web
printing machine embodying the same will be given, reference being had to the
accompanying drawings forming a part of this Specification, in which :—
Figure 1 is a side elevation of a web printing machine with the present improve-
ments, the perforating rolls being carried respectively by the shafts of the type and
impression cylinders.
Fig. 2 is a plan view of the same.
Fig. 3 is a transverse section on the line 3--3 of Fig. 1.
Fig. 4 is a diagram showing the lead of the web.
Fig. 5 is a detail of the means for adjusting the web turner; and
Figs. 6 to 12 show various modifications.
Figs. 6 and 7 are respectively a side diagram and plan view of a construction in
which one of the perforating rolls is carried by the shaft of the type cylinder.
Figs. 8 and 9 are similar views of a construction in which one of the perforating
rolls is carried by the shaft of the impression cylinder.
Figs. 10, 11, and 12 are respectively a side diagram and plan view with the
inking rolls omitted, and a rear elevation, of a perfecting machine.
Referring now particularly to Figs. 1 to 5, the frame of the machine shown,
consists of the base A. on which are mounted the side frames BC, in which is
supported the printing and delivery nechanism M.
The side frames consist only of front and rear standards connected at their
upper ends by a plate extending longitudinally of the machine, the frames being
enlarged at the front of the machine sufficiently to provide bearings for the
printing, inking, and cutting rolls, and each side frame being provided with a
projecting arm D, forming supports for the web roll, a very light and simple frame
thus being formed.

page_text: In this frame are mounted the shafts E, F, the former carrying the type
cylinder G, and the latter the impression cylinder H.
Upon these shafts are carried also the cutting rolls, which, with the delivery
mechanism shown, consist of a pair of perforating and feeding rolls IK, the
former being provided with a perforating blade 1, and the latter with a groove 2,
and both being provided preferably with rubber bands 22 for increasing their hold
upon the edges of the paper, all as shown in Figure 3. The shaft F is driven by
a pulley L connected to any suitable source of power, and the two shafts E F, are
geared together by gears 3, as usual in this class of mechanism.
The shaft carrying the impression cylinder and grooved roll, is preferably
mounted, as shown, in bearings adjustable by means of screws 4 at each side of
the frame, in order to secure the accurate adjustment necessary for printing and
perforating rolls.
These
The inking mechanism may be of any suitable form, but preferably, for
simplicity of construction, consists of the form rolls M and the inking roll N, the
latter being a self-feeding roll or supplied with ink in any suitable manner.
rolls also are driven from the shaft F by gears 3, and the form rolls are preferably
mounted in spring bearings, and the inking roll made adjustable by screws 5, as
shown.
For the purpose of transferring the web from the printing rolls to the
perforating rolls, there is provided a turner O, of well-known construction, around
which the web is led from the printing to the perforating rolls, as shown in the
drawings, and as hereinafter described.
For the purpose of adjusting the turner O, so as to secure the correct registry
and severance of the printed sheets, the following means are provided :-
The turner O is provided at its lower end with a fork 6, which slides transversely
of the machine on a short shaft 7, supported by a standard 8 projecting upward
from the base frame. The turner is carried upon a rod or shaft 9, which is
supported in forks 10 formed in crank arms 11, carried by a rock shaft 12,
supported in the side frames of the machine, the shaft being held in position
within the forks by pin 13, the withdrawal of which permits of the removal
of the turner. The crank arm 11, on one side of the machine, is provided
with a downwardly extending arm 14, thus forming a bell crank lever. This
arm 14 is forked at its lower end, and embraces a grooved nut 15, carried by, and
moving on a screw 16, mounted in the frame, and provided with a handle 17, by
which it may be operated. For supporting this screw 16, a slotted lug 18 extends
inward from the frame of the machine, and the screw is secured in said slot so as
to rotate therein and move transversely of the machine, but to be held from longi-
tudinal movement by shoulders 26. The rock shaft 12 is mounted to slide in the
frame, and is extended outside the same at one end, and the extended end is
provided with an arm 19, which carries a screw 20, entering the side frame, and
provided with a handle 21, by which it may be operated, the movement of the
screw 20 in the frame thus carrying the shaft 12 and turner O transversely of the
machine, these parts being held in their adjusted position by the same screw.
The delivery mechanism may be of any form, but consists preferably of the
single set of accelerated tapes P, Q, by which the sheets are delivered to the
packing box R, the tapes P, Q, extending from rolls 23, next the perforating and
feeding rolls, to rolls 24 at the end of the machine, the rolls 23 being driven by
gears 3 from the shaft F. These tapes are arranged, as is usual in this class of
mechanism, so that the sheets are not nipped until they reach the end of the
machine when pressure upon the sheet by rolls 24 and 25, the latter being placed
below the tape and above the line of movement of the same, snaps the sheet
from the web at the line of partial severance.
The operation of the parts described will be readily understood from the
drawings, and a brief statement of the lead of the web:
The web W passes from the web roll at the front end of the machine upward
between the type and impression cylinders G, H, thence downward over roll 27,

page_text: around the turner, and upward in front of and between the perforating and feeding
rolls I, K, where the sheet is partially severed, and passes thence into the control
of the accelerated tapes P, Q, by which, as previously described, the sheet is fully
severed from the web, and delivered to the packing box R.
For the purpose of adjusting the web turner vertically, it is necessary only to
rotate the screw 16 in either direction, when the turner is raised or lowered as
desired, this upward and downward movement. being permitted by the fork 6
moving freely upon shaft 7.
For adjustment of the turner transversely of the machine, the screw 20 is.
operated so as to carry the shaft 12 in either direction, this movement of the turner
and shaft being permitted by the free movement of the screw 16 in the slotted
lug 18, and of the fork 6 longitudinally of the shaft 7.
The construction described provides a very simple and convenient means of
adjusting the turner, while the latter is held firmly in its adjusted positions,
transverse movement being prevented by screw 21, vertical movement by screw 16
and nut 15, and swinging movement by fork 6 and shaft 7.
In the construction thus far described, two shafts only are employed for
carrying the printing cylinders and perforating and feeding rolls, the latter being
mounted in line respectively with the type and impression cylinders.
In Figures 6 and 7, a construction is shown in which three parallel shafts are
used, one perforating roll being mounted upon the shaft E of the type cylinder,
the grooved perforating roll K being mounted upon an independent shaft S. In
this construction, the turner O is preferably placed above the printing cylinders,
and the inking mechanism M, N below the same, as shown, but any other arrange-
ment of parts may be adopted.
The lead of the web W is substantially the same as that described in connection
with Figures 1 to 4, the web passing first between the type and impression
cylinders G, H, thence upward over roll 27 and around the turner, and thence
forward over the perforating roll I on the shaft of the type cylinder, and downward
between it and perforating roll K to the delivery mechanism.
In Figures 8 and 9, a construction is shown in which, as in Figures 6 and 7,
three parallel shafts are used for the printing cylinders and perforating rolls, the
perforating roll 1, in this case, however, being mounted, not upon the shaft of
the type cylinder, but upon that of the impression cylinder, the shafts S of the
perforating roll K being mounted between the shaft of the impression cylinder and
the web roll. In this construction also, the turner is preferably mounted above
the printing rolls, but the construction of Figures 6 and 7 is varied, the type
cylinder G being placed between the impression cylinder and the perforating roll K,
and the inking rolls M, N outside the printing roll, and in the same horizontal
plane. The web W is led upward between the type and impression cylinders,
thence over roll 27, and around the turner, and downward between the perforating
rolls I, K to the delivery mechanism.
Figures 10, 11, and 12, show one form of a perfecting press of this type of
machine. In this construction, the usual pair of printing and perfecting cylinders
are used, the perfecting type and impression surfaces G, H, being placed between
the printing cylinders G, H, and the perforating rolls 1 K, all. the printing and
perforating rolls being mounted upon two shafts, as in the construction shown in
Figures 1 to 4. In this construction of a perfecting press, two turners are
necessary, a second turner O' being introduced to transfer the web for the
perfecting impression.
The arrangement of the parts may be varied widely, but a simple and convenient
arrangement is shown, in which the shafts E, F are arranged in a vertical plane,
and the turner O' is placed horizontally, and the turner O vertically, the inking
mechanism being placed above the printing cylinders. The web W is led
horizontally under the roll 28, to and between the printing cylinders G, H, thence
around the cylinder H, and over and around the turner O, returning under the
roll 29 between the perfecting cylinders GH, thence downward around the roll 27

page_text: and over the turner Oreturning below the perforating roll I, and horizontally
between it and the perforating roll K, whence the web passes to the delivery
tapes:
It will be seen that by the construction described, there is provided a very
simple and compact machine, in which the number of operating parts are greatly
reduced, and that all these parts are mounted close together, and driven by a single
short train of gears. The use of intermediates for transferring power from one
end of the machine to the other, as usual in printing machines, is entirely avoided,
the action of the parts thus being rendered more positive and accurate.
By mounting the perforating and feeding, rolls upon the shafts of the type and
impression cylinders, the amount of adjustment necessary in the machine is lessened,
these parts being always in adjustment relatively to cach other; it being necessary,
therefore, only to adjust the web turner for the purpose of securing the accurate
registry and perforation of the sheet. While it is preferable that the perforating
rolls should be carried by the shafts of the printing cylinders, thus lessening the
number of shafts to be driven, and securing the relative accurate adjustment of
these parts, some of the advantages of this machine, especially those of simplicity
and compactness, may be obtained by mounting the perforating rolls on independent
shafts in line with the shafts of the printing cylinders, and such construction forms
a part of the present invention.
In printing machines of small size, to which the improvements constituting the
invention are especially applicable, it will be found that supports at each end, as
shown, will be sufficient for the shafts carrying the printing cylinders and per-
forating rolls. In large machines, however, it will sometimes be found desirable
to provide a central support for these shafts.
It will be understood that the delivery mechanism and inking mechanism may be
of any desired form, these features constituting no part of this invention, and that
other devices commonly used in web-printing machines, as, for instance, numbering,
dating, folding and pasting mechanisms, may be used in the machine in which the
present invention is embodied.
