How II Runs.
Running the end of the paper from
Il roll through the press under and
over the various rollers Is accomplish
cd in from five to ten minutes, accord
ing to the cXpcrtncss OF the operators,
and is called threading the machine.
There arc two beds on the press, which
are stationary, each carrying for an
oight-pagc paper four forms locked IN
ChasCs, one page to a form or chase,
as on all ether fiat bed presses, except
that the arrangement of the forms Is
different. -Four forms are placed side
by side on each bed teach bed. by the
way, weighs about a tom and reaching
CTosswise of the press, the lower bed
containing pages two, seven. three and
six, and the upper bed containing pages
one. eight. four and five. The work oil
putting the eight forms on the press
and locking them In ready for print
ing consumes less than ten minutes and
the press Is ready to begin work. The
power being on, the lever Is pulled. the
machinery of the press moves, and the
paper on the roll continues on it's way
through the press, coming back to the
same end Of the press from which l.
started, printed, cut, counted, folded,
with the incest precision, ready for de-
livery To the reader, and at the rate OF
i50O to COCO completed newspapers per
hour, as required.
The press runs so easily and quietly
that the observer does not realize its
speed until he approaches the delivery
box and sees the swlftncss with which
the papers arc delivered. Every part
OF the press acts In unison, and no mis-
take can occur except through careless
ness OF the operator.
Printing Process.
The process OF printing takes place
altogether ut one end of the press
Here are situated the two stationary
horizontal beds already mentioned on
which the pages of type are placed.
Moving backward and forward over
these beds are two impression cylinders
mounted upon reciprocating crossheadI
and carrying rollers TO guide the web
and linking rollers. One OF the cross
heads Is clearly shown In the accom-
panying illustration at the termination
of the long driving gear. The press
pritns n newspaper with every half
revolution Of this driving wheel, half
the pages being printed ON the lower
red where the paper Is passing TO the
right, and half ON the upper bed as the
web passes round towards the folder.
There Is thus left an interval for thu
ink TO dry between the impression on q
given paper of the lower cylinder and
that of the upper. For the supply Oi
ink there are four ink fountains.
The Great Equalizer.
A most ingenious device OF til,
press, which makes II more remark
| able invention than the rotary stCrcO-
type presses, is the cqualizing mechan'
ism by which portion Of the web l.
! stopped to receive the impression
from tho type, while at the same time
the paper Is continuously entering thl
machine from the roll at one END
and passing steadily into the folder al
the other end Of its course. This is ac'
complsheI by looping rollers operated
! 10y equalizer cams which receive thu
constantly incoming paper, at the same
time delivering the constantly Outgo'
ing web, while the paper between these
two looping rolls remains stationary n
It's path Of travel during the time II Is
being printed upon by the two i'm
preston cylinders.
Immediately after the impressions
are taken, and the printing Is done by
the cylinders in their travel in clthcl
direction, that portion OF the web which
has been stopped Is moved forward tx
proper distance to bring sufficient
blank paper for the next impression, OF
the printing of the next paper.
After the printed web or paper
leaves the upper cqualizing roller, II II
slit by revolving cutter, in tive
parts, each part containing four pagci
In the case OF an eight page paper. one
Of these parts passes over a couple o
angle bars" bringing this portion %
the web into the direct line elevator o.
the other part. At this point THU
stream of paste can be supplied to thu
inner sheet, securely fastening the two
parts of the paper together. This past
Is not ordinarily used in an eight pag'
paper, but is when a six page paper Il
printed, which can be done as easil!
as to print the eight page style. Boil
parts now travel together over the V
shaped former, which practically
makes the second fold.
The printed web, now brought h
single page size, passes through III
short cutting cylinders which scye
each complete paper from the web.
Third Fold.
