Part 2 Looping
Tracking Down the Problem Part 2 Looping
First, always check your thread
path. Thread should pull smoothly with no obstructions.Second, check the thread tensions. It’s very important to be certain the upper
pretension is adjusted so the thread doesn’t slip through the main tension.
See Tips Part 5 for more information on adjusting tensions.
| Common Causes | Remedies |
| Upper thread tension is too loose. | Tighten upper thread tension. |
| Elastic threads, such as polyester. | Tighten upper thread tension. Adjust take up spring (check spring), tighten the tension on the spring. Adjust the length of the take up spring. Try alternate brand of thread. |
| Needle too small. | Larger size needle. |
| Stitch too long. | Shorten stitch length. |
| Angle of the stitch. | Change stitch angle. Best angle is the X direction. Y direction stitches cause excessive pull on the thread as the needle moves back (frame moves forward). |
| Density too tight. | Less density or make more than one sewn pass over same area. |
| Dense material. | Larger needle or lubricant. |
| Elastic or rubbery material. | Stiffer backing, larger needle or lubricant. |
| Inadequate foot clearance. | Adjust foot clearance. Too low and foot can pinch thread causing a loop. |
