Highest Quality  BOBBIN CASE.
Juki Bobbin Case For Industrial Lockstitch Single Needle Sewing Machines.
Complete Bobbin Case with built in anti-spin spring or brake to assist with over spinning of the thread on the bobbin when starting and stopping.
Part # : 110-38759 (11038759)
MADE IN JAPAN.
These are Bobbin Cases with
NO BACK LASH spring inside
.
A special
anti-spin spring
is built into the bobbin case assembly to
prevent the bobbin from spinning
when the machine is suddenly stopped. If the bobbin spins when the machine stops, there is a good chance that a single loop of thread will fall out of the bobbin case. This condition will cause the thread to snap as soon as the operator begins to sew.
No Back Lash
Bobbin Cases are also
required
by sewing machine manufacturers for use in machines with
bobbin thread undertrimmers
. The anti-spin spring
adds slight additional tension
to the bobbin thread and
stabilizes the bobbin thread
just prior to actuation of the
trimmer mechanism
.
