What To Know
- One of the crucial components of an overlocker is the needle, and it’s important to understand the distinction between sewing machine needles and overlocker needles.
- The sharp point of the sewing machine needle can cut through the fabric, causing the threads to fray and the seam to weaken.
- Additionally, the lack of a groove on the sewing machine needle can prevent the thread from flowing smoothly, leading to thread breakage and tension issues.
Overlockers, also known as sergers, are specialized sewing machines designed for finishing raw fabric edges. They create a secure and professional-looking seam while trimming and overcasting the excess fabric in one step. One of the crucial components of an overlocker is the needle, and it’s important to understand the distinction between sewing machine needles and overlocker needles.
Differences Between Sewing Machine Needles and Overlocker Needles
While both sewing machine needles and overlocker needles are designed for piercing fabric, they have several key differences:
- Tip Shape: Sewing machine needles have a sharp point, while overlocker needles have a blunt or ballpoint tip. The blunt tip prevents the needle from cutting through the fabric, allowing it to slide between the threads.
- Groove: Overlocker needles have a groove on the side, which allows the thread to flow smoothly and prevent fraying. Sewing machine needles do not have a groove.
- Thread Path: Sewing machines use a single needle and thread, while overlockers use multiple needles and threads. The groove on the overlocker needle helps guide the thread through the machine’s threading system.
- Size and Compatibility: Overlocker needles are typically shorter and thinner than sewing machine needles. They are specifically designed for the overlocker’s threading system and may not fit in a sewing machine.
Can I Use Sewing Machine Needles in My Overlocker?
The short answer is no. Using sewing machine needles in an overlocker can damage the machine and produce unsatisfactory results. The sharp point of the sewing machine needle can cut through the fabric, causing the threads to fray and the seam to weaken. Additionally, the lack of a groove on the sewing machine needle can prevent the thread from flowing smoothly, leading to thread breakage and tension issues.
Choosing the Right Overlocker Needles
When selecting overlocker needles, it’s essential to consider the following factors:
- Needle Size: The needle size refers to its thickness. The appropriate needle size will depend on the fabric thickness and thread weight.
- Needle Type: There are different types of overlocker needles available, each designed for specific fabrics and applications. Some common types include general-purpose needles, stretch needles, and metallic needles.
- Brand Compatibility: Overlockers are compatible with specific needle brands and models. It’s important to consult the manufacturer’s instructions to determine the appropriate needles for your machine.
How to Insert and Thread an Overlocker Needle
1. Raise the needle bar: Use the handwheel or lever to raise the needle bar to its highest position.
2. Loosen the needle clamp: Locate the needle clamp screw and loosen it using a screwdriver.
3. Insert the needle: Hold the needle with the groove facing the back of the machine. Insert the needle into the needle bar and push it up until it stops.
4. Tighten the needle clamp: Use the screwdriver to tighten the needle clamp screw securely.
5. Thread the needle: Pass the thread through the thread guide and the eye of the needle.
Troubleshooting Overlocker Needle Problems
If you encounter problems with your overlocker needle, such as thread breakage or skipped stitches, check the following:
- Needle is bent or damaged: Replace the needle with a new one.
- Needle is the wrong size or type: Choose the appropriate needle for the fabric and thread you’re using.
- Needle is not inserted correctly: Remove the needle and reinsert it, ensuring it’s fully seated in the needle bar.
- Thread tension is incorrect: Adjust the thread tension according to the manufacturer’s instructions.
- Fabric is too thick or thin: Adjust the needle size or choose a different needle type for the fabric you’re sewing.
Final Note: Sewing Machine Needles vs. Overlocker Needles
Understanding the differences between sewing machine needles and overlocker needles is crucial for achieving optimal results in your sewing projects. Using the correct needles for your overlocker will ensure smooth operation, high-quality seams, and prevent damage to your machine. By following the guidelines outlined in this blog post, you can confidently select and use the appropriate needles for both your sewing machine and overlocker.
Basics You Wanted To Know
1. Can I use universal needles in my overlocker?
No, universal needles are not suitable for overlockers. They have a sharp point and lack a groove, which can damage the machine and produce poor-quality seams.
2. How often should I change my overlocker needle?
It’s recommended to change your overlocker needle after every 8-12 hours of sewing or whenever it becomes bent or damaged.
3. What is the difference between a 130/705H needle and a 130/705H-S needle?
The 130/705H-S needle has a slightly larger eye than the 130/705H needle. It’s designed for sewing with heavier threads or multiple layers of fabric.
4. Can I use a sewing machine needle to sew on an overlocker?
No, sewing machine needles are not compatible with overlockers. They have a sharp point and lack a groove, which can damage the machine and produce poor-quality seams.
5. How do I know if my overlocker needle is bent?
Check the needle by holding it against a flat surface. If you notice any curvature or deformation, the needle is bent and should be replaced.
