These small, cylindrical components are essential for the lower thread supply in Janome sewing machines. They hold the thread that interlocks with the upper thread to create stitches. Different models of Janome machines may require specific types, often categorized by class (e.g., Class 15) or style (e.g., metal or plastic). Correct selection ensures proper tension and smooth operation.
Using the correct type for a given machine model is crucial for preventing thread jams, tension problems, and inconsistent stitching. Choosing the appropriate material, whether plastic, metal, or pre-wound, can impact stitch quality and machine longevity. Historically, bobbin design and materials have evolved alongside sewing machine technology, improving performance and reliability. Proper maintenance, such as regular cleaning and checking for damage, contributes to optimal sewing results.
