This is a symptom of thread nesting or bird nesting (you can search for information on the internet). Usually, it means the thread is not seated completely in the tension disk or the upper tension is too loose.

Remove the thread. ALWAYS RAISE the presser foot and rethread from the beginning. Verify the thread path is correct. Set the upper tension to the midway point between high & low number. If it is still making loops underneath, you need to tighten the upper tension and retest until the two threads meet in the middle of the fabric.

You may need to adjust the tension knob for the thread . Usually located above the needle . screw it in a little at a time or perhaps it has a number scale if so increase to a higher number a little at a time till the stitches become correct.

My sewing machine is a Janome Magnolia 7330. The hand wheel will not manually turn backwards to raise or lower the needle. When sewing, the bobbin stitches are loose and looped.


I would find a local sewing machine sales and repair shop near you. You will need to have them look into this, it may be a timing issue or a broken or damaged part.

My Husqvarna diamond top thread keeps breaking while doing loop embroidery. It sews a couple of stitches and then you can hear when the thread breaks. Ive tried changing the needle and bobbin, and cleaning...


Hello

Primary causes of upper thread breakage:


-- misthreading: pull all the thread off and thread again, using the manual, step by step. Read each step aloud before you do it. (sounds dumb, but helps.) (And make sure you thread the takeup lever!)

-- thread has wrapped itself around a thread guide or spool pin from one of the breaks. Take the spool off the machine before rethreading.

-- bad or damaged needle. Replace with the right size for the fabric, turned correctly (backwards needles skip stitches)

-- dirty machine, especially in the bobbin case area: review cleaning instructions and do it, using brush and vacuum only

-- bad/cheap thread: should not be slubby or break easy. Try another spool.

-- top thread tension too tight. 4 is normal for most fabrics, most stitches.

Tips;

1) do a light cleaning (brush and vacuum) every day you sit down to sew.

2) replace the needle if you hear it hit metal, if you've got a really bad thread jam, if you see it deflect as you sew (for instance, sewing over the side seam on jeans when hemming). Replace every 3-8 hours of actual stitching time anyhow.

3) buy good quality thread

4) when your machine isn't sewing right, stop; take all the thread off of/out of the machine (bobbin out of bobbin case, spool off spool pin) and give it a quick cleaning. Rethread from scratch, carefully. If that doesn't fix it, do it again, then replace needle and rethread one more time, manual in hand (yah, even if you've threaded it 8 million times before). #4 is curative about 98% of the time. The other 2% often requires professional attention.

I bought Brother sewing machine Model XL 2230, And could not get a good stitch. Keeps giving me loop either on top stitch or down stitch. Dont know if the single needle can't do straight sewing and dont...


The foot is on the side. Make sure it is clean. Take off the plate and remove the bobbin cleaning all the lint and thread out with q-tips. Oil if needed. Make sure you are using the same thread in the bobbin as on top. Rethread the machine making sure you do it correctly. Change needles using Schmetz as it is shorter and I have found Singer and white label needles are too long and cause problems and well as break easily as they hit the bobbin and cause looping. Not sure what you need to know about the foot. It should have a handle on it so you can put it up or down. Google Brother model XL 2230 and download a manual to find lots of info about your machine.

I hit a pin with my Singer Stylist 7258. It jammed. I changed the needle, rethreaded it, and turned it off and on, but it snarls up thread under the fabric, and seems that the thread does not always loop...


Good that you changed the needle. Did you rethread just the needle or did you rethread the machine? You may have already taken these steps, but if not, here is what I would suggest:

1. Replace the old needle (which you did), even if it looks ok, as it may be bent or have a tiny burr or other damage that isn't easily visible. Make sure the needle is seated properly - facing forward and fully inserted.
2. **Completely rethread the machine, making sure the thread is going through the take-up lever. It can easily pop out when the machine jams, and you can't always see that the thread is out of place. That could explain why the thread doesn't loop properly around the bobbin.
3. Remove the bobbin and clean any knotted thread or lint from around the bobbin carrier. Canned air is great for cleaning the lint.
4. Replace the bobbin, making sure the thread-end is clipped neat, not frayed or knotted.
5. Try sewing on some practice fabric to make sure the stitches are going to form properly before returning to your sewing project.
Good luck!

Bobbin tension


If the looping is happening on the underside, it is your top tension that is to blame, conversely looping on top is bobbin tension.........take a look HERE for detail on cleaning lint buildup.

Top tension should be set around the middle of the range, usually 4 - 6.

I would not advise playing with bobbin tensions, however, you can take the needle plate off to clean the hook race area (where bobbin case sits) ...this is good housekeeping, my wife does this every time she replaces the bobbin....just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint, if there appears to be fine dirty deposits, a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit will do the trick.
