And curl their outer edges into the curl of the ends is injected a
rubber gasket material. Graphically illustrated. It looks like this.
Later on
when the ends are seemed on the Can body this material will provide an air tight
bond between the body
and the M.P.'s now to make the candidate this body maker
actually operates too fast for us to see how they can bodies for so after the body
blanks which you saw being cut earlier are fed into the body maker. We will follow.
It's intricate steps in slow motion and with graphic illustration.
First the body blanks move to a not ging stage here small notches are cut from the
corners to eliminate a double thickness of metal
when the ends are seemed on the body
blank is then formed
and hooked into the familiar shape of the can around the body maker's
he has
next they are bumped to form
and tighten the side seam the
one who has
the form the body then passes over flexing wheels to a hot solder bath where a
solder is applied to the outside of the side seam the side seam is then wiped off
and cooled by a blast of air.
Then the bodies speed along to where they are flange studies Jan.
So the tops
and bottoms will fit on here
you will see why the body blanks were not not just the lemonade a double thickness
of metal by the side seam overlaps the flange part only two layers
come together at this point.
Thus permitting a perfect seal
when the end pieces are seemed on air in the can making plant only one of the
end pieces is double seemed in place and the other end left open.
So they can maybe easily failed at the canneries this operation is extremely
important. It calls for the utmost precision.
One hand is placed on the Can body.
It curls over the flange on the body and precisely the right amount.
Remember that rubber gasket material in the curl of the end pieces.
While this material provides a bomb between the layers of metal to ensure a
permanent air tight seal as they are pressed together to give us the finished
double seat. Later when the cans have been filled in a can
or a the other end will be double seemed on in the same way with exactly the same
precision but returning to the can making line.
Our cans with only one hand seemed on leave the double seam are ready for final
testing. Fresh air is a wonderful thing
but not in a can by means of air pressure this machine detects a can
that might leak air
and tosses it out as a suspect to be checked separately against a
can like the red one. We know to be a leaker.
And
that is the seemingly simple can require such precision in its making
that any variation in excess of a few thousands of an inch are sufficient to cause
automatic rejection.
There's ability to achieve high speed production with such precision as place the
can manufacturing industry in the front rank of the mass production leaders of the
world
but how do all these billions of cans get to the right place at the right time food
cans for instance.
Well that takes a lot of planning a lot of experience
and good teamwork between the can manufacture the canning and the farm.
Actually there's hardly a minute of the day or night
that you won't see trucks loaded with containers
or freight cars similarly loaded on their way to the canneries scattered across the
land such journeys are initiated at the canneries But there's more to it than just
loading a truck or freight car because with all manned controls.
There's still one thing about nature he can't change the uncertainty of the weather.
So the weather holds good crops should be ready about the thirtieth give
or take a day on either side.
So you want your candor on the and you make it the twenty first twenty first
that is how many way better have two carloads a day Telapak is complete.
You'll get them all I know I.
And depend on you if there's any change in the weather you'll be hearing from us.
We've got to be ready when the crop is and
that readiness depends upon the weather not weather
and its effect on a crop like peas for example is a mighty unpredictable thing you
can't depend on guesswork.
That's why the American Can Company develop this machine the tender ometer.
It shows one of the crop has reached the proper stage of maturity for best quality.
Such information together with the Council of agronomists sent out by the Can
makers help scanners
and farmers select the right time for harvesting well anything I'd say you can
start taking him in next Monday and a special time of the day or the I leave
that up to me. Monday is OK with me
but sometimes unexpected things happen. Well it's plenty hot out here.
The temperature shot right up.
We took another turn around a reading this morning
and it shows are these are going to be ready much sooner than we think we've got
them can right away. OK And of course we'll get a chance to hear.
What the worry will get in the time though.
And so it goes for the entire Can making industry operate on this principle enough
cans at the right place at the right time to meet the canners need for us
every year. Billions of cans go out into the world packed with the yield of land
and sea to say nothing of myriads of other products for Man's you
and Eric can must speak for itself where every children
when every twelve whatever it contains the contents must be in perfect condition
word for that is.
Dependability dependability built by the turn allows vigilance of
modern industry and science into every single cat or whatever the contents.
But ever their ultimate purpose goal is satisfaction.
There is nothing more important than serving the health
and well being of multitudes of people providing protective containers for the food
of a nation is such a service about which Here's something to remember NO NO shown
don't do that you're throwing away the best cause.
It certainly was a very low do nothing.
But the liquid they were cooked in is full of vitamins and minerals.
But throwing this away would be like well like doing a chicken
and throwing away the broth right for not only do canned foods contain as much
nutrition as fresh cooked foods but nature's own nutrients are seal them
when these foods are at their very best and none of the precious values can escape.
Now let's eat the likely and we'll add the P.S.
Just a few minutes before we are ready to say the least little keep them hot
and you know they are already cooked perfectly. You can depend on that.
Dependability
and nutrition these essential characteristics of canned food are assured by
constant laboratory studies of canning techniques the first laboratory in the
industry devoted to such studies was established by the American Can Company in one
thousand nine hundred six.
Since then scientific study
and research have grown with the industry today it reaches into every phase of
canning and can making ten play.
For instance ten itself comes from far off lands us every
world crisis threatens its supply
that can making industry is therefore working on coatings and bonding materials
that will replace stand in can making will be better than tan
and best of all always available here on our own continent the
industry constantly looks to the combined scales of science
and manufacturing to solve many problems which directly affect our daily lives.
For instance behind this simple familiar twist of the wrist lies a story of
teamwork typical of the achievements in the can making industry
that bring the homemaker convenience and satisfaction. Here's how it came about.
Ed this is Mr Ward the coffee roaster I told you about stored meat out of our
research staff pleased to meet you. How do tell us what you're up against Mr Ward.
Well it's short and sweet. We pack coffee.
Here is a container using it's good but it's not airtight.
You know coffee when it's freshly ground and exposed to air.
Naturally lose its freshness and there goes our flavor.
Has been on the shelf for a while. You can guess what we've got.
Stale coffee probably if it stays there long enough right then folks don't like it.
Well there's only one real answer to that since is the air the ruins your coffee.
You've got to take the air out of the can.
But that can cause the can is what you need that sounds good
but I've never seen a back room coffee can because easy to pack
and easy for the housewife to open.
Well those are our problems and they're toughens. Let's work on them.
The chair of the. You've got to develop a Can strong enough to hold a vacuum.
And yet still be easy to warp.
Let me think it over a while. I'll try to come up with something. But I warn you.
It may be designing machinery to produce this. You let me worry about that.
Going to get an idea.
Oh hell this is John. Got a pencil and paper.
Wake up. This is what you've been waiting for.
Grab a pencil.
All right. OK. Draw yourself a sanitary tan.
Only a little shorter
and about five inches in diameter.
Got it. Yeah go on. Now. Draw bead on it.
About one inch from the top.
Right now.
Cut away part of the canvas shell of the inside.
Now. Inside.
They can drop a collar from the bottom of the be up to the underside of the cover
and add a curl of the top of the collar got it
all right. That puts the bottom of the collar into the B.
To hold it in place
and just above the draw a double score on the outside of the chain.
Now at the end of the school
or over the side of the padded tongue about a half an inch long.
Right now and then like that. Sure we can make it but what is it.
What is it. Well put it to your neck to wind off a scored strip
and that our new easy opening back and coffee can.
Then I think you've got something but.
About makin packing while John had the answer for that too.
After the cans are filled with coffee
and loosely covered they pass into a chamber where the vacuum closing machine draws
out the air. Almost at the same time that covers are tightly doubled seemed on.
So that no lawyer can possibly get back again.
So from then on the vacuum coffee can not only solve the roasters problem of
protecting his product freshness even though months
or years of my past before the cans were opened
but it also meant the consumers demand for easy opening more than
that had led to other developments
that make the housewives job easier for it was an ideal container for override a
zero product especially shortening so. So far freshness and convenience.
Instead of this.
This and for sanitarium protection neatness planet.
Instead of this this.
Or perhaps the whole story can be summed up in the vast difference between this.
And with all it signifies in our modern way of life. This.
So our basic idea adapted to human needs is like a pebble dropped in a pool the
need is the Pebble the pool our democratic way of life
and the answer the Rings spreading ever outward touching the lives of millions of
our everlasting good.
That is why this key is not just a little household gadget symbol of challenges
mapped
and victories won for the good of all many many challenges
and many answers. Whether containers of steel or paper
or a combination of both they are products of the can makers imagination and skill.
Here are some of them just a few all of them.
We know we recognize each one instantly familiar to us from almost daily use.
Many of their colorful and informative labels as seen on store shelves
or skillfully lithograph them permanently baked on in the can making plant all as
part of the can making process
this to while not a can it had its beginning in the minds of can makers who scale
in shaping ceiling and mass produce.
Metal containers was applied to the problem of fashioning from paper the ideal
disposable container for the dairy industry.
Yes these containers are familiar because they are part of the pattern of our
living an essential indispensable part of our way of life even recreation
just another type of can.
Just as if these tennis balls were peas or beads or beans.
They will come out as perfect as they were
when they were put in while man may survive without tennis.
There have been all too many occasions
when a life has depended upon the blood plasma in
that very same kind of can coming out as perfect as it was
when it went in to the men and women who make the can.
There could be no greater satisfaction than its use for a purpose such as this
Thus every new ideas sets in motion a succession of ideas
that expand an ever widening circle saw the miracle of the can
continue bringing to countless supporting industries added expansion
and prosperity to millions of people more jobs greater security
and better way of life the can manufacturing industry ranks among the first ten
indispensable industries of the world.
Hundreds of thousands of men and women in the United States Canada ally last
and elsewhere depend upon its continuing prosperity its bright future is there's
this achievement this present day flowering of the seeds of enterprise first
planted by the Pioneer can makers of America
and nurtured by their successors has truly brought about.
Miracle of benefits to our be a miracle which continues daily for all people
for a day every day is Harvest Day Daily we have the assurance
of nature's bounty both for today
and tomorrow much we have today
and our promise of the future is ever more and more
and just as harvest time means more than the ending of one bottle season contained
within itself the seeds of another fruitful spring.
So this tumblers little servant of your daily life contains not just a product
but symbolizes a more abundant life for all freedom loving people everywhere in the
world. This is the miracle of the can.
