Brother Bobbin Case Innov-is F & NV Series

The Brother bobbin case is an important spare part for your sewing machine. It is needed if the original bobbin case is damaged, worn out, or no longer functional.

Typical signs of a defective bobbin case are:

• Uneven or irregular stitch pattern

• Thread jams in the hook area

• Bobbin thread issues despite correct settings

• Visible nicks or damage to the case

If the bobbin case is damaged, the bobbin thread tension often can no longer be regulated precisely. In this case, it should be replaced to achieve a clean and even sewing result again.

Note:
A bobbin case is only replaced if the existing one is damaged or no longer functional.
