The Making Of Wall Paper.
METHOD BY WHICH THE coLoRs ARE
ArPIIED.

METHOD by WHICH THE coLoRs ARE :,
APPLIED.
The paper on which the designs are
printed is manufactured especially for |
this purpose, and is of varying weight. |
II is received in large heavy rolls, re-
sembling the rolls of paper used in
newspaper offices. This paper is first
passed through the grounding" ma
chine where the ground color, be it
light or dark, is applied TO the surface
of the paper by rollers, and then is
rubbed in and thoroughly distributed
by means of set of brushes, some of
which move from side TO side, while
Others are stationary. Some of the i'm
proved machines can apply this ground
color TO two rolls at the same time.
If it is desired that the paper shall
have the silvered appearance seen in
some papers "mica" coat, as it is call
ed, is applied. This coloring matter is
pulverized isinglass mixed with white
lead. The colors of this mixture can
not well be shaded, and, therefore, in
such cases the differences in shade are
made by using paper of different col.
ors.
After the ground color has been ap-
piled the roll of paper is placed on a
framework and is slowly unrolled, and
then carried on an endless band over a
large drum, resembling the cylinder of
printing press. The machine on
which the paper is printed, in fact, re-
sembles very closely a cylinder printing
press, except that the process of print
ing is reversed the paper passes over
the drum or cylinder, and the designs
are printed by the rolls, which are
placed on the lower part of the frame
work and revolve in the same direction
as the cylinder. Each roller is stamp
ed with different part of the figure
forming the general design to be pro-
duced, and each of these portions of
the design is printed in distinct color
APPLYING THE CoLoRs.
The colors are applied to the print
ing blocks or rolls by an endless band
of muslin passing through tank filed
with the color for that particular block.
As the band covered with the color
passes from the tank it travels over or
beneath piece of metal having a tooth
ed edge, technically known as "doc-
tor" and all supeihuous paint is re-
moved, running back into the tank.
The printing rolls are so adjusted that
each portion of the design is closely
joined together, producing a harmon
lous effect. These printing machines
print from two to twelve colors at the
same time. The colors are prepared
by a special process. so that they do
not "run" or blend. The heavier shades
are applied last, as general thing
though the arrangement of the colors
and the printing blocks depends in
great measure upon the design which
is to be produced.
After passing over the cylinder the
printed paper is carried to the dryer on
an endless chain. This dryer extends
the whole length of the factory, and by
an ingenious arrangement the endless
chain carrying the paper passes around
pillar and returns to the other end oil
the room, As the paper passes of
from the cylinder it is caught up at in
tervals of about eight feet on wooded
sticks called Carriers" These sticks
are moved along by little projections
on the endless chain, the paper hang
ing in loose loops or folds between the
.'carriers.' The paper is carried along
for distance of 200 or 800 feet owe
coils of steam pipe, and thus is quick
ly dried. After hanging for length
OF time varying from six to twenty
four hours, the paper is taken from thu
carriers and laid in dry room, wher'
it remains until the drying process il
thoroughly complete. 1t is then taker
to another room, where, by ingenious
machinery, it is rolled in lengths o
marketable size.
COAT OF BRONZE POWDER.
If it is desired to apply coat o
bronze powder to make figure, tn
figure which is to be thus treated i
stamped on the paper as it passe
through the printing machine with
heavy coat of varnish. Then, afte
passing once over the coil of steam
pipe in order that the other colors ma
be dried, the paper is sent through
long air-tight box, in which this bronz
'dust" is sifted over the surface from
perforated tray, and the paDer the
passes around the end of the travele
and back over the hot air or stear
pipes.
The finest and most elaborate design
however, are printed by hand. Fac
color must be stamped separately, an
any one can at once distinguish pape
that is printed by hand from that prin,
ed by machine. In the former at on
of the margins will be found, at dis
tances of about eighteen inches, fin
lines or dots containing the colors form
ing the design. These are the mark
guiding the men in their work of stamp
ing the pattern. The block or die fo
each separate portion of the patter
which is to be printed in certain Co
or is eighteen inches in length. Th
workman presses this die upon a pa
covered with the color, and then place
it upon the paper as it lies on the tabl
in front of him, taking care that tn
guide at the edge of the die joins tn
mark left on the margin of the paper
Placing swivel over the block, b
presses a lever with his foot thus STAMP
ing the form of the die on the paper
A boy attendant spreads the paper o.
rack, where it is permitted to dry
and it is then taken to another machin
where the same process is gone throug
in printing another portion of the dc
sign in another color, and this process
is repeated in some instances a doze
or more times, until the entire desig
in all its more or less harmonious blend
ing of colors, is produced.-Neao Yor
