What is tension in embroidery machine?
When thread tension is in balance (and designs are properly stabilized) embroidery can run smoothly, with beautiful results. When tension is off, you might see clumps of thread on the underside of the fabric, bobbin thread showing on the front of the design, looping threads, or thread breaks.
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.
Why is my thread bunching 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 you know if embroidery tension is correct?
When doing machine embroidery, the tension dial should be set somewhere between 2 to 6. If the stitches appear loose, turn the tension up one notch and embroider again.
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.
Why are my stitches loose embroidery?
Common Causes of Birdnesting
The main source of birdnesting or looping is improperly inserted or threaded bobbin or running the embroidery machine with no bobbin. … Unthreaded take-up levers will always cause birdnesting. A tight bobbin tension, together with highly loose needle thread tension, can cause birdnesting.
How do you adjust bobbin tension?
To increase the bobbin tension – tighten the screw by turning it to the right (clockwise). To decrease the bobbin tension – loosen the screw by turning it to the left (counterclockwise). Move the screw only a quarter turn or even less at a time.
Why is my top thread looping?
Looping on top generally means the needle tension is too loose. Change your needle. The golden rule for needle selection is to use the smallest sharpest needle that can carry the thread through the fabric without damage to the thread, fabric, or needle. Change your thread.
