How do you adjust the bottom tension on an Elna sewing machine?
Open the bobbin compartment and remove the bobbin casing. If the bottom stitches are loose, turn the screw closest to the bobbin case’s center 1/8 turn to the right with a small jeweler’s screwdriver. If the bottom stitches are too tight, turn the same screw 1/8 turn to the left to loosen the stitch.
Why is the bottom stitch on my sewing machine loose?
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 adjust the bobbin tension on my embroidery machine?
Bobbin thread appears slightly on the right side (top) of fabric. If this occurs, turn the slotted-head screw (-) clockwise, being careful not to over-tighten the screw, approximately 30-45 degrees to increase bobbin tension.
Why is the tension wrong on my sewing machine?
Needles, threads, and fabrics: Different thread sizes and types on top and in the bobbin can throw off basic tension settings. A needle that’s too large or small for the thread can also unbalance your stitches, because the size of the hole adds to or reduces the total top tension.
Why is my bottom stitch not straight?
If your thread is pulled tight on the underside and not forming an even stitch then (counter-intuitively) it’s usually the top thread tension that’s wrong. Sometimes very lightweight fabrics such as sheers can get dragged down into the machine so it’s a good idea to use a straight stitch plate.
What should bobbin tension be set at?
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).
How tight should bobbin tension?
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.
How do I fix the bobbin tension?
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.
