NBL (No-Back-Lash) Spring. Specifically designed for the Pfaff 1445 industrial sewing machine, this specialized spring is essential for maintaining control over the bobbin during high-speed stops and starts.

Product Overview
The NBL spring (Part 9101989105) sits inside the bobbin case to prevent the bobbin from spinning freely when the machine suddenly stops. By providing just the right amount of braking pressure, it eliminates thread over-run, which is a leading cause of tangles and "birdnesting" at the start of a new seam.
