the
length
of
the
fabric
coming
from
the
part
with
a
larger
dimension
L
gets
longer,
while
the
length
of
the
fabric
coming
from
the
part
with
a
shorter
dimension
L
gets
shorter.
In
other
words,
the
left

right
length
of

will
be
equal
if

is
equal
at

The
difference
in
right
and
left
lengths
of
the
fabric
can
be
corrected
by
advancing
or
backing
Sinker
so
as
to
reduce
the
difference
of

to

-
0.2

In

Sinker
is
necessary
to
be
pushed
