Each Year
Packing Holders Are Made
Rapidly In Factories

San Francisco, Oct 81 Over l,OOO,-
100000 cans are thrown away every
year. Once used they are put in the
garbage cans by the thrifty. house
wives and ultimately find theft way to
the dumps of the big cities. None OF
them Is used mole than once, writes e.
p. Mcdonald in the San Francisco
Call
The big factories now are making
two kinds of fruit and vegetable cans
the old fashioned can that has been
in common use for more than so years
and the sanitary can, which has been
manufactured for about FIVE years. Ac-
cording to an official of one of the rep
resentative can companies, the sani-
tary can will, within eight or ten
years. supplant the old fashioned can,
Besides the ordinary fruit and vegeta-
BILE cans, they make what is known as
general line-paint pals, lard pals,
oyster cans and varnish cans.
The tomato cans most generally
used are known as the sanitary, and
the hole and cap cans. The hole and
cap can is used extensively by pack
ers Of peas, corn, tomatoes, beans and
other vegetables.
The operation employed in making
this can is entirely automatic. The
cans are made at the rate of $4,000 to
10000 a day on each line, day con-
sisting of 10 hours. A line consists
of a machine called the body maker,
into which is fed the blanks In the fiat
the blank sheets of tin. The body
maker folds the sheets and rolls them
into cylinders.
The cylinder then is carried along
automatically to the next station,
where the side is scanned. Then 1t
finds its way to a machine called the
header, and into this header are fed
the ends and tops. On one side of the
header the tops come down and on the
other side the ends come down. This
puts the ends on the cans.
From the header they progress to a
crimper, which crimps the ends or
fianges against the body Of the can.
From the crimper they go to the sold
ering machine, where both ends are
soldered.
Next comes the tester that tests the
cans automatically to see that they do
not leak If can is imperfect it is
thrown aside. From the tester they
20 to the drier and are dried thor
oughly No water is allowed to get
inside the can, the hole being covered
with rubber during the process of
tetsing.
The finished cans are counted auto
matically and packed in the cars by
young men, who use long prOngs which
they insert in the mouths of the cans.
1t takes only about eight workmen
to operate an entire line, In some OF
the larger factories as many as IL
lines are operated for 10 hours a day
1t will thus be seen that big can fac
tory has capacity of almost 100000
cans day 100000 in round numbers
In other words, less than a hundred
men are capable of turning out 1000,
600 packing cans in single day
Ends, before going to a header are
all cut on what are termed gang press
es. The sheeted tin is fed into gang
press, and as the press comes down il
cuts out SO of these ends, both bot
toms and tops-an equal number oi
each. Then the little round cap fount
in the center of the top of the ordin
ary tomato can is cut from the same
, sheet. This cap has little ribbon o
