Butterfly B1201B/T - Single Head 12 Needle Embroidery Machine Manual
Bobbin thread
The B1201B/T uses style ‘L’ bobbins and bobbin cases which are also known as Standard
Bobbins. We recommend using prewound polyester bobbins with cardboard sides. The bobbin is
located inside the bobbin case and is near the bottom of the machine under the needle plate. The
bobbin should be cleaned and replaced regularly to ensure proper tensions. Lint typically clogs the
bobbin case which will produce variations in tensions and poor embroidery quality. It’s a good
indication that it’s time to replace the
bobbin case if the bobbin pulls out of
the bobbin case rough after the case has
been cleaned. Because bobbin cases are
so inexpensive, it is recommended to
purchase new ones rather than replace
or repair used ones.
To remove the bobbin case from
the hook of the machine, pull the
bobbin case handle while extracting the
case. When inserting the bobbin case
back into the hook, make sure that the
handle is pointing straight to the right.
Do not pull the handle when inserting
the case back into the hook.
To thread your bobbin into the
bobbin case, follow the following steps.
Step 1 – Insert the style ‘L’
prewound standard cardboard sided
bobbin into the bobbin case.
Step 2 – Insert the bobbin thread into the slot/notch on the side of the metal bobbin case.
Step 2/B – When pulling the bobbin thread through the notch, the bobbin should spin clockwise
when looking at the side/top of the bobbin. If it is not spinning
clockwise, remove the bobbin and flip it over.
Step 3 – Pull the bobbin thread through the notch and
under the hook located right by the notch.
Step 4 – Place the thread under the pig tail of the
bobbin case. Be sure that the bobbin thread passes from the
bottom opening of the pig tail and exits for the very top and not
from the side of the pigtail.
