(Cl. 101-181)
The present invention relates to devices for
maintaining the register of a printed web upon
-which a plurality of printing operations are to
be effected. Where a continuous web is subjected
‘ to more than ‘one printing operation, as, for
example, where the web is to receive multi
color printing, the importance of maintaining
accurate registration of the web with respect to
the printing surface of the respective printing
cylinders will be readily apparent. Inaccuracies
in such registration result in imperfect printing,
and registration, ‘therefore, becomes a highly
'
’
upon it in such fashion as to register correctly‘
with the previous impression.
Figure 4 is a view similar to Figure 2 showing
the condition existing when the web is leading,
that is, when the web reaches the printing sur- 5
face too soon to have accurate registration of the
printing surface with the prior impressions.
Referring to the above drawinzs, Figure 1
illustrates the pertinent portions of a printing
press upon which the present invention may be 10

A further object of the invention is to provide

A further object of the invention is to provide

from which it is carried to the third printing unit 25
consisting of printing cylinder 20 and impression

impression upon the web which must register
accurately with the impression made by the
printing cylinder H.
In order that this im- 30 '
pression may register accurately with the im
pression made-by cylinder I'I, mechanism is pro
vided, in accordance with the present invention,
this mechanism now being described.

The printing cylinders are driven by a com- 35

suitable driving connections such as worm gears ~

In operation, the printing cylinders are en

II by means of a wire II which also includes a
lamp or other indicator 0! to give an indication
of the existence of a leading web.
In order that the web tensioning roll is may
be adjusted to compensate for leading or lagging
conditions of the web, a reversible motor 63 is
suitably connected thereto. The speci?c connec
tion and operation of the web tensioning roll by
the motor It forms no part of the present in 10

‘matically in the drawings. In the construction
' illustrated, the motor ‘I is a 3-phase reversing
motor and may be controlled by means of any
suitable reversing mechanism operated by relays 15
responsive to current ?owing through the re
spective wires 58 and ii. In order that this may
be illustrated more fully, two interlocked relays
N and ii are illustrated, relay 64 being adapted
to close contact members 66, i‘! and 68 while 20

plate circuit by means of a wire II, the condenser
having a rating of one microfarad in the typical
circuit above referred to.

A relay II is connected in the plate circuit, this
relay having a contactor 52 which is adapted to

nected to a suitable power source by means of a
wire 85 while terminal 54 is connected to the
circuit interruptor 26 by means of a wire IS. The
interrupter 26 is adapted to engage a stationary
contact ‘1 which is connected to the contact
finger ii.
The 'interruptor 26 is operated by
means of a cam 25 which, as above described, is
mounted on or synchronized with the rotation of
the drive shaft 22.

The directional switch 21,- ss previously‘ de
scribed, is mounted on the drive shaft 22 or syn

Contact ?nger 32 is connected to a wire II
70 which is connected in turn to lamp II and to
wire II which is connected to the source of power
-to which .wire I! is connected. In the circuit
formed by the wire II, a lamp or other suitable in

Figure 2 illustrates the case where the web H 60
is in accurate registry with the printing surfaces
of the‘respective printing cylinders. The index

photo-electric cell 34 so that an instantaneous
current impulse is transmitted to the grid of the

A lagging web is illustrated in Figure 3, where
(Si)
the actual position of the indexing indicia is in
dicated by the solidly drawn spot on the web Ii,
and the position of the indicia for accurate reg
istry is indicated by the spot shown in dotted
lines. In this case, contact ?nger 26 is in en

therefore, supplies voltage to the lamp 8! through 70
the segment 30, and at the same time energizes
the relay ll, thereby energizing the motor I4 and
increasing the tension in the web ii.
In Figure 4 is shown the case where the web
is'leading. Here, at the instant when the in 75
