Abstract
A bobbin system for use with a sewing machine is disclosed. The system includes a bobbin and a thread wound around the bobbin. The system also includes an anti-unwinding member arranged around the thread to ensure that the thread does not dislodge and unwind off of the bobbin thus reducing or eliminating entanglements and jamming of the moving parts of the sewing machine.
