REGUI.ATIN:; THE

THREAD

TENSICN

For

ordinary

stitching,

the

tension

of

the

upper

and

lower

thread

should

be

equal

so

as

to

lock

ooth

·

threads

in

the

center

of

the

fabric.

The

tension

of

the

l::obbin

thread

is

regulated

by~

of

the

tension

screw,

but

it

is

preferable

to

keep

it

rather

weak.

Once

it

is

regulated,

the

perfect

stitch

can

be

obtained

by

adjusting

the

tension

of

upper

thread

by

increasing

or

decreasing

the

tension.
