The Bobbin Winder Assembly is a spare part that is a critical component of a sewing machine’s bobbin winding system. It is responsible for winding thread onto the bobbin, which is used to create the lower thread of a sewing project.
The Bobbin Winder Assembly typically consists of a bobbin winder spindle, a bobbin winding mechanism, and a motor or hand crank to power the assembly. When engaged, it winds thread from the upper thread spool onto the bobbin, creating an even and consistent layer of thread.
If the Bobbin Winder Assembly becomes worn or damaged, it can cause the bobbin winding process to become uneven or unstable, resulting in poorly wound bobbins that can cause thread tension issues or even thread breakage. In such cases, it may be necessary to replace the Bobbin Winder Assembly with a new one.
