Winding
the
bobbin
(Pfaff
^63
sewing
head)
In
order
to
avoid
unnecessary
interruptions
of
the
sewing
operation
it
is
advisable
to
have
a
full
bobbin
available
at
all
times.
Important
note
Pfaff
3516-1/?!^-928/01
and
-1/23-928/01
machines
are
equipped
with
a
different
bobbin
winder.
Its
operation
is
described
in
Section
19.
3.1«
Threading
the
machine
for
bobbin
winding
(figs.
3
and
Pass
tlie
thread
from
spool
(Fig.
3)
through
a
hole
of
the
upper
thread

through
guide
10
(Fig.
^),
through
both
holes
of
thread
guide
11
and
clockwise
around
tension
12.
Then
wind
a
few
turns
of
thread
clockwise
on
bobbin
13.
3o2.
Regulating
the
thread
tension
(Fig.
4)
The
thread
tension
is
regulated
by
turning
knurled
disc
l^u
Turn
this
disc
cloclcwise
to
decrease
the
tension,
or
counter-clockwise,
to
increase
it.
For
sewing
monofil
and
transparent
threads
reduce
the
tension
to
a
minimum.
30.
Adjusting
and
starting
the
bobbin
winder
(Fig,
k)
Tension
12
should
be
so
adjusted
that
the
thread
runs
onto
the
middle
of
the
bobbin.
This
ensures
an
even
distribution
of
the
thread
on
the
bobbin.
If
adjustment
is
required,
this
will
be
carried
out
by
a
mechanic.
To
adjust
the
amount
of
thread
to
be
wound
on
the
bobbin,
loosen
screw
15
and
adjust
stop
dog
l6
vertically.
Set
the
stop
dog
higher
for
more
thread,
or
lower
for
less
thread.
After
the
adjustment,
tighten
screw
15.
Push
down
stop
dog
l6
to
start
the
bobbin
winder.
If
resistance
is
felt,
turn
the
bobbin
slightly.
The
bobbin
winder
stops
automatically
when
the
desired
amount
of
thread
has
been
wound
on
the
bobbin.

Care
should
be
taken,
however,
that
there
is

space
between
