Both Very Important
Taken alone, either one Of the
discoveries would be regarded as Of
the utmost significance, but to-
getfer they are hailed as the most
Important advance in the field Of
rubber manufacture since the dis
cOvery of INFLAMMATION nearly q
century ago.
Speaking Of the new processes,
the India Rubber World, mouth
piece of the rubber industry, says
In its current issue:
"By the combined use Of this
rubber and the latex treated fabric,
the United States Rubber Company
is in a position to make it's prod
ucts of a quality that cannot be
surpassed by any product or pro-
cess now known"
The new processes have been
perfected by the development de.

The new method Of extracting
rubber from latex Is mechanical and
of too technical a nature to be de-
scribed here. 1t supplants the
method now in universal use on the
plantations whereby the particles of
rubber in the latex are coagulated
by the introduction Of chemicals
into the 1atex just after 1t has been
taken from the tree, and also super

crease in tensile strength and -resis-

Rubber Company itself is modest
in its claims regarding the super
iority of the crude rubber coagu-
lated in this way, other rubber eX-
perts do not hesitate to predict that

revolutionize coagulating methods
throughout the world and give to
consumers rubber goods Of a dis
tinctly better quality.
Several coagulated plants of the
new type are now in operation or
in the course of construction by the
United States Rubber Company,
both in the United States and the

The new web fabric process. in its
immediate aspects, is Of even greater
interest to the rubber industry In

process because most of the work
of coagulation has been done at
