Goss Printing Press Company, Chicago, 111., a
corporation of Illinois
Application March 21, 1935, Serial No. 121152
28 Claims. (01. 101-220)
rl‘he invention relates to new and useful im
provements in rotary printing presses, and more
especially to such improvements in the web sup
plying means for such presses.
5
Objects and advantages of the invention will
be set forth in part hereinafter and in part will
be obvious herefrom, or may be learned by prac
tice with the invention, the same being realized
and attained by means of the instrumentalities
10 and combinations pointed out in the appended
claims.
The invention consists in the novel parts,
constructions, arrangements, combinations and
improvements herein shown and described.
The accompanying drawings, referred to here
in and constituting a part hereof, illustrate one
embodiment of the invention, and together with
the description, serve to explain the principles
of the invention.
Of the drawings:
erably a group of four, that is in pairs across
and along the press, supplying the webs for each
press unit, the web from any of said rolls being 01
directable to any and all of the printing couples
of the press unit. Web turning devices, and web
tension controlling means are located beneath
the press unit and between it and its group of
web rolls. It will be seen that this affords a sim
ple, compact and very low web supply unit of
very great capacity; that the web rolls can be run
on a dolly right to position to be mounted on the
press without lifting or endwise shoving of the)
web roll, and by the employment of movable
angle bars all endwise adjustment of the web
rolls is obviated. Two web rolls are maintained
for each perfecting mechanism, one active and
one in reserve, and the fresh web can be spliced
Fig. l is a side elevation of a printing press
on without in anywise disturbing any of the
other webs or web rolls. It will be understood
Fig. 2 is an end view of the bottom part of
that the foregoing general description of the
embodied invention, and the following detailed
embodying the invention;
Fig. 1, looking from the right;
Fig. 3 is a top plan of the web supply means
with the press unit removed; and
Figs. 4, 5 and 6 are diagrammatic” showings of
the printing couples and various arrangements
of a web running therethrough.
Objects of the invention are to provide an
improved web supply mechanism for rotary
presses and more especially such a mechanism lo
cated in a substructure beneath the press. The
invention provides web supplying and control
35 ling mechanism which is simple, compact and re
liable, and which can be installed and operated
in a relatively low substructure.
The invention
provides such a mechanism which requires only
minimum, and also very easy, handling of the
40 web rolls, and which avoids all lifting or upend
ing of the rolls, or endwise movement and han
dling thereof in restricted spaces. The means
a;
end relation along both sides of the press; a
plurality of alternately operating web rolls, pref
for mounting the rolls are fully and readily ac
cessible from the exterior of the press and from
both sides thereof, and the necessity for end
wise registration of the web rolls, as by an end
lay mechanism, is avoided.
To secure these and other objects and advan
tages, the present embodiment comprises, in con
nection with a press unit having a plurality of
horizontally arranged and a plurality of verti
cally arranged perfecting couples, a plurality of
web rolls horizontally disposed and with their
axes perpendicularly to the couples, and ar
' ranged at either side of the press and in end, to
description as well, are illustrative and exem
plary, but are not restrictive of the invention.
Referring now in detail to the embodiment of
the invention illustrated by way of example in
the accompanying drawings, the invention is
shown exemplarily applied to a printing press
of the type shown in my copending application .
Ser. No. 732,793, ?led June 28, 1934, although so
far as concerns the main features of my inven
tion it is also applicable to other types and kinds
of printing presses. Said herewith illustrated
press comprises a series of press units mounted
in unit frames, each of said units comprising
a plurality of printing couples arranged both
vertically and horizontally in the unit, whereby
a web may be run either across or vertically from
one printing couple to another to perfect a web,
or it may be run through both the vertically and
horizontally arranged couples for multicolor.
Any number of the press units may be mounted
upon a bed, in a longitudinal series, for the de
sired size of product, with one or more folders
as may be needed.
In said embodied form there is provided a press
unit I having side frames 2, in which are jour
naled a printing couple having a printing cyl
inder ‘! and an impression cylinder 8, and ar
ranged vertically above said couple is another
printing couple having a printing cylinder I l and
an impression cylinder l2. Mounted in the other
half of the unit, in substantially horizontal re
lation to the ?rst-mentioned printing couple is a
10

2
printing couple having a plate cylinder l4 and an
impression cylinder I5, and above said couple
and in substantially horizontal relation with cou
ple ll, I2 is a fourth printing couple [8, l9. Two
webs may be run through the unit either hori
zontally or vertically to be perfected, or a single
web can be run through all the couples for mul
ticolor, and various other combinations can be
made. The unit frame is centrally transversely
divisible and is thus capacitated to be mounted
in the press as single units or as double units,
and a collar 58 serves to regulate the spring ten
sion. Fixed to the end of shaft 54 is an arm 63,
and pivoted to arm 63 is a rod 64, pivoted at its
other end to lever ‘65 of the brake mechanism on
one of the web roll spindles 29. Web guiding
rollers r—-l to r-—8 are shown and the number
and position of these may be changed and varied
as desired to secure different one color and multi
color printing combinations as may be desired.
Leads of a single web through a plurality of 10
horizontally arranged and a plurality of verti
shown in Fig. 1, and as described in my before
mentioned copending application.
The web supply comprises a plurality of hori
zontally and longitudinally disposed web rolls,
and with the embodied double perfecting unit
four web rolls are provided for each unit, being
arranged in pairs at either side of the press, end
to end, and with their axes horizontal and trans
verse to the printing couple, the pairs of web
rolls at one side of the press being in transverse
alinement with those at the other side. Web
turning mechanisms are provided between the
web rolls and the printing couples for presenting
the webs to the couples and for registering the
webs longitudinally of the printing cylinder with
out the necessity of moving the web rolls axially.
Referring now in detail to the embodied form
of the web supply mechanism, on the press side
frame, at either side of the press there are sup
porting brackets 21 and 28 for the spindle 29 of
the web roll w, the brackets being conveniently
mounted on the press side frame, there being two
web rolls arranged end to end beneath the press
unit at one side of the press (Fig. 1), and two
web rolls in the same relation directly opposite
at the other side of the press (Fig. 2), there be
ing as embodied four web rolls beneath a press
unit, said web roll supporting means are in ?xed
or stationary position, that is in permanent lon
gitudinal position, with reference to a given
printing couple and is the regular alternate sup
ply for that particular couple. It will be seen
that the replenishment of the web rolls is ex
ceedingly simple and easy, as the new roll may
be run on the dolly into position closely along
side the brackets 21 and 28 and shifted directly,
and on the same level, into place on the brackets
without any lifting or upending of the roll or any
50 need for pushing it lengthwise into .a contracted
space and there lifting or pushing it into position.
In said embodied form, the web roll directly
across the press from the running roll is the
reserve roll, and either of these webs may be led
to a common web-turning device and from it
directed into the press.
As embodied, the web runs over a guide roller
33, journaled on the frame and runs thence
preferably to an automatic tension controlling
60 mechanism. Said mechanism, as embodied,
comprises a roller 31, journaled in boxes 38, which
are slidably mounted in bearing brackets 39
mounted on the press frame. The journal boxes
38 are acted on by springs 42, coiled about rods
43, which have screw-threaded spring tension ad
justing nuts 44. The web passes from roller 38
to a roller 41, which is journaled in slidable
bearings mounted in openings 48 on the machine
frame. The pintles of roller 41 are mounted in
a pair of slotted arms 52 and 53, ?xed on a shaft
54,v journaled in the press frame. Projecting
downwardly from shaft 54 is an arm 55 to which
is pivoted a rod 56, longitudinally slidable in a
bracket 5'! mounted on the machine frame. A
75 spring 58 is coiled about rod 56 in compression,
cally arranged printing couples are shown in Figs.
4, 5' and 6.‘
The brake mechanism may be of any desired
form, and as shown, comprises a pulley 66, ?xed .5
on web roll spindle 29, and acted on by opposed
brake shoes 61 and 68, which are connected by
suitable levers to the lever 65. A similar connec
tion is made to the brake mechanism on the
spindle 29 of the opposite web roll. Further de
tailed description is not required. The web then
passes over a guide roller 13, journaled in the
press frame, and then passes about a turner bar
‘l4, located to turn the web into parallelism with
the printing mechanism, the web passing thence
over guide roller 15, journaled in the press frame,
the web thence passing upwardly to the printing
mechanism as shown in Fig. 1. The turner bar
14 is movably mounted so as to bring the web
from successive web rolls into alinement without 3O
the necessity for a side-lay mechanism, or any
other means for moving the web roll, to effect
register of the web with the press. As embodied,
each end of the turner bar is provided with a slot
Tl, the ends of the bar resting upon slotted plates 35
18, mounted on the machine frame. A bolt 19
passes through each slot, the turner bar being
thus movable to and fro to effect the side regis
tration of the web as desired.
The invention in its broader aspects is not 40
limited to the speci?c mechanisms shown and
described but departures may be made therefrom
within the scope of the accompanying claims
without departing from the principles of the in
vention and without sacri?cing its chief advan
tages.
