The Brother DDL-8700 industrial sewing machine uses a class 15 bobbin. This is a crucial detail for anyone operating or maintaining this powerful machine. Understanding the bobbin type ensures you're using the correct one, preventing potential malfunctions and ensuring smooth operation. Using the wrong bobbin can lead to skipped stitches, broken needles, and even damage to the machine itself.
What are Class 15 Bobbins?
Class 15 bobbins are a standard size and shape used in various industrial sewing machines, not just the Brother DDL-8700. They're characterized by their specific dimensions, ensuring proper fit and function within the machine's bobbin case. These bobbins typically have a larger capacity than domestic machine bobbins, allowing for longer sewing sessions before needing a change.
Where Can I Find Class 15 Bobbins?
Class 15 bobbins are widely available from industrial sewing machine suppliers, both online and in brick-and-mortar stores specializing in sewing machine parts. Many online retailers specialize in industrial sewing supplies and will offer a variety of bobbins, including those specifically compatible with the Brother DDL-8700. Always ensure you're purchasing bobbins specifically labeled as "Class 15" to guarantee a proper fit.
What Happens If I Use the Wrong Bobbin Type?
Using an incorrect bobbin type in your Brother DDL-8700 can result in several issues:
- Skipped stitches: The bobbin may not feed correctly, leading to inconsistent stitching and potentially ruining your project.
- Broken needles: A poorly fitting bobbin can put excessive strain on the needle, leading to breakage.
- Machine damage: Persistent use of the wrong bobbin can cause damage to the internal components of the machine, leading to costly repairs.
- Uneven tension: Incorrect bobbin size and shape can disrupt the delicate balance of tension between the needle and bobbin threads, resulting in inconsistent stitching.
Are there different types of Class 15 Bobbins?
While the overall classification is Class 15, subtle variations might exist among manufacturers. Some bobbins might be slightly different in material (plastic vs. metal) or have minor dimensional differences. It's advisable to stick with bobbins specifically recommended by Brother or known to be compatible with the DDL-8700 to avoid any compatibility issues.
How often should I replace my bobbin?
The frequency of bobbin replacement depends on your sewing tasks and the bobbin's capacity. It's always good practice to replace the bobbin when it's about ⅔ full. This helps maintain consistent thread tension and reduces the chance of thread jams. Regularly checking your bobbin's fill level is an essential part of proper machine maintenance. Replacing your bobbin when nearly empty is a good preventive measure against many potential machine problems.
By ensuring you use the correct Class 15 bobbin in your Brother DDL-8700, you'll maintain the machine's optimal performance and extend its lifespan. Remember to always source your bobbins from reputable suppliers.
