Needle breaks can be a frustrating and time-consuming problem for embroiderers. But by understanding the common reasons why needles break, you can take steps to prevent them from happening and ensure your projects are completed without interruption.
Here’s a guide to help you resolve the problem:
1. Check the Needle
-
Ensure you are using the correct needle type and size for the fabric. A 75/11 or 80/12 needle is commonly used.
-
Make sure the needle is inserted correctly, with the scarf (indentation) facing the back and fully pushed up into the needle clamp.
-
Replace the needle if it is bent, dull, or broken.
2. Check Thread Tension & Thread Path
-
Incorrect thread tension can cause extra stress on the needle, leading to breakage. Ensure the tension is balanced (not too tight or too loose).
- Verify that the thread is correctly threaded through the tension knobs and thread guides. Misthreading can cause uneven tension, pulling on the needle.
3. Check the Bobbin & Bobbin Tension
-
Make sure the bobbin is correctly placed in the bobbin case and the tension is properly adjusted.
-
If the bobbin tension is too tight, the upper thread may be pulled too much, increasing the chance of needle breakage.
4. Check the Timing
- If the needle is consistently breaking, there might be a timing issue with the Rotary hook and needle. Use the guides below to check the timing and adjust if needed.
EM Series Proper Timing
TC/SWD Series Proper Timing
MT/CHT2 Timing
5. Check the Presser Foot Height
- If the presser foot is too high, the fabric may bounce and move during embroidery, causing the needle to strike incorrectly and break. Follow the guides below to adjust your Presser Foot Height.
Presser Foot Adjustment EM-1010
Presser Foot Adjustment TC/SWD
Presser Foot Adjustment MT/CHT
6. Check the Hooping & Stabilization
-
Improper hooping can cause the fabric to move while stitching, leading to misalignment and needle breaks. Ensure the fabric is hooped tightly but not overstretched.
-
Use an appropriate stabilizer (e.g., cutaway stabilizer for stretchy fabrics).
7. Lower the Speed
- Running the machine too fast can increase the chance of needle breakage. Try reducing the speed, especially on difficult fabrics.
