The Key To More Jobs
Did you ever stop to think how much you depend
upon your neighbor down the street—and how much he,
in turn, depends upon you? This principle in our society
is especially active in our jobs, and in the satisfying of
our daily needs.
For example, there is the product you help to make
at Firestone. Your neighbor needs it, and he buys it.
Maybe he is your milkman, your grocer, or the man who
sells you electricity and gas.
This principle of interdependence points up how the
money you paid for, say, your shelter and clothing last
month was provided through the product you help to
make, and its sale on the market. On the other hand, the
money which goes to your neighbor for his services and
goods helps him to supply his own needs and, in turn,
allows him to continue serving you.
The businessman who serves you is likely a Firestone
customer now. If not a customer, he is a potential one.
Let him know you appreciate his services and remind
him that your patronage is made possible through sales
of the company for which you work.

Compounding and mixing of a
batch of rubber in the process
of building a tire is much like
the baking of a cake. The more
care and attention given to this
operation, the more improved is
the mixed stock—and the end
In tire manufacturing, bales
of natural or synthetic rubber
are inspected, split and plasti-
cated, in preparation for com
pounding. This is the second
major operation in the building
of a tire.
More than 800 types of final
compounds have been establish
ed for making various Firestone
tires. Final compounds vary ac
cording to the purpose for which
they are to be used — treads,
sidewalls, plies, beads, tubes,
chafer strips. These compounds
are the result of extensive re
search and are selected only
after exhaustive testing by de
Adds To Quality
All raw materials used in the
compounds are tested thorough
ly. They are sampled as they are
received in the plants, and un
dergo rigorous tests before being
released for use.
In the compounding depart
ment of the company’s tire-
building plants, exact amounts of
ingredients are mixed with the
rubber, to comply with rigid
specifications. Working as a
team, compounders weigh the
proper amounts of pigments for
each formula designated by the
In addition to the rubber stock
and certain mixing oils, ingredi
ents for compounding include—
Carbon black to make the rub
Zinc oxide for speeding up the
Anti-oxidants to guard against
effects of weathering
Accelerators to speed up the
Sulphur to make possible the

Since 1900, our gross national

This record of over half a cen
tury shows some ups and downs,
but the general trend is express
ed in an ever-mounting curve.
Many producers are small

The Firestone Company, dur
ing a recent fiscal year, spent
more than $400 million for out

of all the money taken in by the
company was paid out for ma

To maintain sales, please customers and meet com
petition, Firestone tires must be reasonable in cost and
outstanding in performance on the highway. They must
not check or crack, they must be flexible and resilient;
and they must give motorists a safe, comfortable ride.
Compounding—one of the major steps in the building
of tires—is an example of how quality is built into tires
rubber to give it such qualities
as strength, elasticity, resistance
to solvents, and to render it

The quality of a tire and the
service it gives the customer are
—to a great extent—determined
by the precise measuring and
weighing of pigments.
Accelerators, sulphurs, anti
oxidants and retarders are criti
cal basic ingredients and must
be weighed with precision.
Pieces of rubber, pigments and
oils which have been thus weigh
ed and checked according to lab
oratory formula, are formed in
to a mixture, called a “batch”.
The Banbury Machine
The batch is next sent to the
Banbury mixer. This machine
can be likened to a giant mixing
bowl. It forces the rubber and
pigments through a pair of ir
regular rolls, chopping the ma
In the Banbury, the batch is
mixed according to laboratory
specifications. Instructions tell
the operator how to mix, how
long to mix, proper temperatures
to maintain, and when to add
After the batch has been
through the Banbury mixer, it is
sent through the pelletizer ma
chine for additional mixing. It
is then forced out through a steel
sleeve which has small holes
in it. A rotating knife slits the
material into small pellets,
which are then water-cooled,
sprayed, dried and then sent
through the Banbury again for
additional mixing. Out of the
Banbury for the second time, the
material goes through a series of
mills, finally emerging in the
form of sheets. They are spray-
cooled and stored on skids, to
await further processing.
Samples of materials are tak
en after each operation has been
completed. These samples are
sent to the Mill Room Control
Laboratory for additional tests,
to insure that proper amounts of
the different ingredients have
When the stock passes these
tests, the laboratory approves
the stock for production.
