Is
wound
on
the
power-driven
bobbin
winder
shown
in Fig. 5.
Place
a
spool
of
thread
on pin 1.
Pass
the
thread
through
eyelet

clockwise
around
and
between
tension
discs

and,
from
the
inside,
through
the
slot
in
the
bobbin.
Wind
a
few
turns
of
thread
on
the

Turn
this
screw
clockwise
for
more

or
counter-clockwise
for
less
thread.
If the
thread
should pile up at
one

the
position
of
the

winder
tension
