Special
machine
is
identified
by
a
Style
number
on
a
name
plate
on
the
machine.
Style numbers
are
classified
as
Standard
and
Special.
Standard
Style
numbers
have
one
or
more
letters
suffixed
but
never
contain
the
letter ‘‘Z’’.
Example:
‘‘Style
39600
(.U’’.
Special
Style
numbers
contain
the
letter
‘‘Z’’.
When
only
minor
changes
are
made in
a
standard
machine,
a
‘‘Z’’
is
suffixed
to
the
Standard
Style
numhe
r.
ixample:
Style
39600
CUZ”.
Styles
of
machines
similar
in
construction
are
grouped
under a
class
number
which
differs
from
the
style
number
in
that
it
contains
no
letters.
Example:
‘396OO.
The
distance
between
the
rows
of
stitches
or
between
the
needles
is
represented
by
a
gauge
number
measured
in
l/64ths
of
an
inch,
going
from
left
to
right.
The
width
of
overeclge
is
represented
by
a
fraction.
Collectively,
the
gauge
number
and
the
width
of
overedge
represent
the
machine
gauge.
Example:
“5
1/8”.
Thus,
5
1/3 gauge
represents
a
distance
of
5/64
inch
between
the
left
needle
(401
stitch)
and
the
right
needle
(503
or
504
stitch)
and
the
1/8
represents
the
width of
overedge
to
the
right
of
the
right
hand
needle.
