Anti – Spin Spring for Bobbin Case
!
What is it for?
Also called the “No Backlash Spring”. It is used
to keep the bobbin from spinning after the take-
up lever has pulled the stitch tight. If allowed to
spin this would cause the bobbin thread to be
thrown out of the groove in the bobbin causing
a very loose tension as the machine starts up
again. Some may say they are not required on
embroidery machines, but with the speeds
achieved on Brother embroidery machines
today, they do make a difference. Running the
machine with out one may not cause an
immediate problem, but they do make a
difference and are needed in these types of
machines with jumbo bobbins. It is strongly
recommend when replacing one, to replace it
with a Brother Anti-Spin Spring p/n#S35583001, which comes in the Brother bobbin
case assembly p/n#S35584001.
!
When do you check it?
At installation of machine and at every bobbin change.
!
How do you check it?
Install a brand new bobbin, (for the correct
weight), in the bobbin case. Hold bobbin case
level with open side up or lay upside down on a
table. The bobbin should be .5mm above the
top of the bobbin case. I recommend the pre-
wound, with two cardboard sides that have a
serration on the flat surface of the cardboard.
This helps slow down the bobbin when in machine.
•
How do you adjust it?
Remove the spring by taking it out with a
small slotted screwdriver. Note how you
took the anti-spin spring out of the bobbin
case to adjust it, as it will only go back in
properly one way. You will need to bend
the spring in two places so that the spring
will be even against the bobbin as
illustrated. Re-insert the spring and recheck
your adjustment. Try to make it as even as
possible all the way around the bobbin
case. You may need to repeat this
procedure a few times until it is correct.
