12 Claims. (Cl. 242-58)
This invention relates to web supply mecha
nisms used with machines adapted to operate
upon a web, such as certain types of printing
machines. More particularly the invention re
5 lates to an adjustable stop mechanism for web
roll supporting reels, provided with high speed
roll changers.
The web supply mechanisms and high speed
roll changers, particularly referred to, are adapt
ed to position a web replacement rollin proper
relation with respect to a running web from an
expiring web roll that web joining mechanism
may be efficiently operated to join the web of the
replacement roll to the running web without
stopping or otherwise interfering with the ma
chine operation. As the position of the replace
ment roll in respect to the running web would
vary if the roll supporting reel was stopped at a
definite position each time it was rotated to bring
20 a roll into position due to differences in diam
eter of the replacement roll, it is desirable to
change the stopping point of the reel in ac
cordance with the diameter of the roll being po
sitioned.
In View of the above desideratum, this inven
tion has for its principal object the provision in
a, Web supply mechanism of an adjustable stop
mechanism for the web roll reels, which is adapt
ed to be manually set in accordance with the
30 measured diameter of the roll supported on the
reel to control the rotation of the reel and stop
it in proper position to dispose the roll in proper
web joining position.
Another object of this invention is to provide
in an adjustable stop mechanism for the above
stated use, means rotatable with the reel and
which is adjustable in accordance with the di
ameter of a web roll, to' operably engage a reel
rotation interrupting device, to actuate the same.
A
A further object is to provide an adjustable
stop mechanism for an electric motor driven
web roll supporting reel and which is adjustable
in accordance with the diameter of the web roll
on the reel, to dispose an electric switch actuat
45 ing member in proper position toè cause the
switch to stop the reel rotating motor, and there
by the reel in the desired roll supporting posi
tion with respect to another operative device
of a machine operating upon a web.
5G
It is also an object of this invention to pro
vide a web supply mechanism of generally im
proved construction, Whereby the device will be
simple, durable and inexpensive in construction,
as well as convenient, practical, serviceable and
55 emcient in its use.
With the foregoing and other objects in View,
which will appear as the description proceeds,
the invention resides in the combination and
arrangement of parts, and in the details of con
struction hereinafter described and claimed,
5
The preferred embodiment of the invention
is illustrated in the accompanying drawings,
wherein:
Figure 1 is an end view of a web supply mech
anism embodying the features of this invention; 10
Figure 2 is a View of a part of the same look

Figure 6 is a top view of the parts shown in 20
Figure 3;
Figure 7 is a sectional view on line 'I-l of
Figure 5; and
Figure 8 is a schematic illustration of an elec
trical circuit adapted for use with the features 25
of this invention.
The web supply mechanism selected to illus
trate the application and use of the features of
this invention is particularly adapted for use
with printing machines "through which a web is
continuously run for operation thereon of the
several parts and devices thereof. The web, in
dioated in dotted lines at I I in Figure l, normal
ly feeds from a roll I2 positioned as shown, the
surface speed of which is controlled by a driven
belt i3 whereby proper tension is imposed upon
the web, it being understood that the belt I3 is
driven from, and substantially in synchronism
with, the operating machine’s parts. The roll I2
together with, in this instance, a spare roll I4
and an expiring web roll I5 is mounted upon re
spective arms I6, Il and I8 of a reel I9.
When the supply 0i web on the roll I2 is sub
stantially exhausted, the reel I9 is rotated to
position the spare roll I4 in place of the roll I2.
the 'expiring web roll therefore assumes the
position of the roll I5, and the web from this roll
I5 runs into the machine as shown at II' in full
lines in Figure l. Considering now, that the
roll I2, as shown, is the replacement roll, the
roll I5 is the expiring roll and the roll I4 is the
spare roll, it is necessary to join the web of the
roll I2 with the running web II’ and provision
for so doing is shown as part of the web supply
mechanism. The web joining mechanism in
2

cludes swingably mounted web deñecting and
63 carried by the lug 62 and disposed in T-slots
severing means herein shown respectively as a
brush 2| and a web cutting knife housed in a'
64 in a casing member 65 of the device 6|. A
cover plate 66 is secured to the casing 65 and is
provided with a central hub 61 which encircles
the shaft 31 and is secured thereto by set screws CA
68. Both the casing member 65 and the cover
plate 66 are formed of semi-disc-like portions
which respectively are secured together by screws
carrier 22. When it is desired to join the webs, a
Ci handle 23 is depressed and through a. cable 24
swings the brush 2| towards the roll |2, pressing
the web Il' thereagainst, whereupon the web
adheres to the end of the web of the roll I2, which
was previously prepared, including the applica~
tion of an adhesive thereto. Substantially si
multaneously with the joining of the webs, the
web ll’ running from the roll |5 is severed be
low the join and the web is then fed into the
machine from the roll l2.
As the amount of the deflection of the web Il'
69 and 1l. The central hub 61 of the plate 66
is provided with an annular flange 12 at one
end, and a hub 13 provided on the casing 65
surrounds the hub 61 and is rotatably retained
thereon by the flange 12.
The casing member 65 and the plate 66 are
adjustably connected together for rotation in
by the brush 2| to cause it to engage the web of
unison by means of one of a plurality of triangu
the roll |2, as indicated at 25 in Figure 1, is re
quired and preferred to be the same in all in
stances when a web join is made in order to
make a proper join in the most eilìcient manner,
it is necessary that provision be made to compen
sate for diiîerences in the diameters of different
web replacement rolls, when such occur. It is,
therefore, contemplated to accomplish this re
lar studs 14, the number of studs corresponding
to the number of roll carrying arms on the reel
I9. Each stud 14 is locked to the plate 66 by a
nut 15, one edge of each stud 14 being engageable 20
with teeth 16 formed in a segment piece 11. The
segment piece 11 is mounted upon a lever 18
which is pivoted at 19 to the casing member 65
between the same and the plate 66.
The lever
sult by the provision of adjustable means where
by the amount the reel I9 is rotated to position
the replacement roll l2 may be controlled and
its movement arrested when the proper position
of the roll |2 with respect to the web H' is
30 reached.
As illustrated herein the reel I9 is rotated by
18 is provided with a thumb engageable part 8|, 25
an electric motor 3| through a worm-gear 32, a
the segment 11 whereby the casing 65 may be
rotated about, and relatively to, the plate 66. A
compression spring 80 having one of its ends
abutting a post 83 secured to the casing 65 and 35
worm-wheel 33, a shaft 34, a pinion 35, and a
gear 36 secured upon a reel shaft 31. The reel
shaft 31, in this instance, is journaled in and
extends between bearing brackets 38 and 38, each
of which is secured respectively to opposing ma
chine frame members 4| and 42. The motor 3|,
adapted through the aforesaid gearing to rotate
40 the reel I9, is under the control of suitable elec
trical solenoids, switches and relays mounted in
a control box 43 and it receives its power from
the conductors Ll, L2 and L3 leading thereinto,
see Figure 8. Direction of rotation coils 44 and
45 disposed in the box 43 when energized re
spectively cause rotation of the motor 3| forward
and reverse. A normally closed circuit limit
switch 46 mounted for convenience upon the
bracket 38 is herein shown connected by a con
ductor 41 to a line wire LLI and by a conductor
48 to the common terminal 49 for the coils 44
and 45. Suitable switches are provided in a
switch box 5| whereby the proper one of the
coils 44 and 45 may be energized to c-ause the
55 actuation of the proper motor controls in the
box 43 to rotate the motor 3| in the desired direc
tion, the switches in box 5| being connected to
line wire LL2 by a conductor 52. Conductors 53
and 54 leading from the box 5| may be connected
60 to the switches therein and to controls of other
operable parts of the mechanism such as the
web joining mechanism controls (not shown)
and a suitable tensioning device operable upon a
floating roller 55 over which the web is threaded
in its passage through the machine, so as to pre
vent operation of the reel motor 3| when these
devices are in operation or vice versa.
Secured upon and rotatable with the reel shaft
31, herein shown disposed adjacent the bearing
70 bracket 38, is a device 6|, see Figures 3-7 inclu
sive, circular platelike in form, which is adapted
by means of a lug 62 to actuate the limit switch
46 when the reel is rotated into a determined
position, the lug 62 being adjustable circumfer
entially about the device 6| by means of T-bolts
which extends from the lever 18 into a recess 82
formed in the peripheral Wall of the casing 65
and open thereat to permit ready access to the
thumb part 8|. Depression of the lever 18 by
pressure upon the part 8| releases the engage 30
ment between the stud 14 and the teeth 16 of
its other end abutting a collar 84 fastened to a
guide rod 85 which is secured to the free end
of the lever 18, continuously urges the lever 18
outwardly insuring engagement of the teeth 16
on the segment 11 with the stud 14 until the lever
is depressed to release the same.
A plate 86 having indicia thereon, which pro
portionally corresponds to various diameters of
web rolls is provided and mounted on the periph
ery of the casing 65. Herein the indicia com
prises a series of lines 81 which are spaced apart
along the plate 86 and are numbered in accord
ance with the diameter in inches of the web rolls
to be mounted on the reel I8. A point mark 88
is provided on the periphery of the plate 66 which. .
when its position with respect to any line 81
is considered, visually indicates the setting, that
is, the relative rotative position of the casing 65
in respect to the plate 66, and thereby the posi
tion of the switch actuating lug 62 in respect to ,
the arm of the reel I8 carrying the replacement
web roll |2.
The operation of the adjustable stop mecha
nism above described is easily and eñìciently
accomplished. The operator measures the dl 60
ameter of the replacement web roll I2 while pre
paring it for having its web joined to the running
web ||’. Before the reel I8 is rotated to posi
tion the roll |2, the thumb part 8| is depressed
and the casing 65, with the lug 62, is rotated
about the plate 66 until thepoint mark 88 is
opposite the line 81 numbered in accordance with
the roll diameter as above ascertained. Release
of the part 8| locks the casing 65 to the plate 66
and the mechanism is set for efficient operation. 70
Rotation of the reel I8 will now be limited to
properly position the roll l2 in respect to the
running web Il’ as shown at 25 due to the
interruption of the actuation of the motor by the
opening of the limit switch 46 by the lug 62. By 75
