The Brother DDL-8700 uses a class 15 bobbin. This is a crucial detail for anyone using this industrial sewing machine, as using the incorrect bobbin can lead to poor stitching, machine malfunction, and even damage. Let's delve deeper into understanding why this specific bobbin type is essential and explore some related frequently asked questions.
What Makes a Class 15 Bobbin Different?
Class 15 bobbins are specifically designed for high-speed, industrial sewing machines like the Brother DDL-8700. Their dimensions, including height, diameter, and the overall shape, are crucial for proper function within the machine's bobbin case. Using a different type of bobbin, even one that seems similar in size, could result in the following problems:
- Poor Stitch Quality: The bobbin may not feed the thread correctly, leading to skipped stitches, inconsistent tension, and ultimately, unsatisfactory seams.
- Thread Breakage: A mismatched bobbin could cause friction and excessive tension, leading to frequent thread breaks. This is particularly problematic in high-speed operation.
- Machine Damage: In severe cases, using an incompatible bobbin can damage the internal components of the sewing machine, requiring costly repairs.
- Difficulty in Winding: The bobbin may not fit correctly on your bobbin winder, making the process more difficult and potentially causing inconsistencies in thread winding.
How Do I Identify a Class 15 Bobbin?
It's crucial to accurately identify a class 15 bobbin. Look for these characteristics:
- Manufacturer markings: Reputable bobbin manufacturers often clearly print the bobbin class number (15) on the bobbin itself.
- Dimensions: While not always readily available without a measuring tool, compare the bobbin's dimensions to a known Class 15 bobbin.
- Compatibility: Always cross-reference the bobbin with your machine's manual.
Where Can I Find Class 15 Bobbins?
Class 15 bobbins are readily available from many sewing machine supply retailers, both online and brick-and-mortar. Searching for "Class 15 bobbins" will yield numerous results. Remember to specify that you need bobbins for industrial machines to ensure compatibility.
Are there different types of Class 15 Bobbins?
While the class number remains the same, slight variations may exist amongst manufacturers. While all Class 15 bobbins should theoretically work in your Brother DDL-8700, it's generally recommended to stick with a well-known and reputable brand to ensure optimal performance.
What happens if I use the wrong bobbin?
As mentioned earlier, using the wrong bobbin can lead to a range of issues including poor stitch quality, thread breakage, machine damage, and wasted time and materials. Always prioritize using the correct bobbin type for your sewing machine to avoid these complications.
By carefully selecting and using the correct Class 15 bobbins, you ensure smooth, efficient operation of your Brother DDL-8700 and achieve high-quality sewing results. Remember to always consult your machine's manual for precise instructions and recommendations.
