To tighten your bobbin tension, turn the tiny screw on the bobbin case a smidgen clockwise. To loosen bobbin tension, turn the screw counterclockwise. A quarter turn or less is a good place to start.
What should bobbin tension be?
Proper bobbin tension is essential to good embroidery. If tension is too tight, unwanted bobbin thread may begin to show on top of your garment and you may begin to experience frequent thread breaks which wastes time and money. Bobbin tensions should be 18 to 22 grams (up to 25 grams when embroidering caps).
When should you tighten bobbin tension?
If the tension isn’t perfect, fix it by adjusting the bobbin spring; tighter if the bobbin thread shows on the upper layer, and looser if the needle thread shows on the underlayer. Make another test seam, and examine the stitches, repeating until the stitch is balanced.
Why is my thread looping underneath?
A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.
How do I know if my bobbin tension is correct?
The thread should unwind just slightly and the bobbin case should drop an inch or two. If the thread unwinds without resistance and the case slips to the floor, your bobbin tension is too loose. If the bobbin case doesn’t budge, your bobbin tension is too tight.
What causes bobbin thread to bunch up?
Bobbin Thread Tangling
The bobbin keeps pulling and jamming collecting a lot of thread beneath your fabric. There are several culprits for this ranging from a dull needle, improper threading or tension. The tension in both your upper and bobbin threads need to be even. The bobbin could also be placed incorrectly.
What number should the tension be on a sewing machine?
As the bobbin thread tension is factory-set and wouldn’t usually be adjusted for normal sewing. So we’ll be talking only about the top thread tension since that’s where you’d usually make the adjustments. The dial settings run from 0 to 9, so 4.5 is generally the ‘default’ position for normal straight-stitch sewing.
How do you fix the bobbin tension on a Singer sewing machine?
Place a small screwdriver on the head of the screw on the side of the bobbin case. Turn very slightly clockwise to increase the tension on the Singer bobbin. Turn slightly counterclockwise to decrease the bobbin tension.
