    Now also take a more specific look at tension issues....

    Please TRY the solution BEFORE giving your considered rating.

    Specific detail on bobbin case adjustment (with picture) near halfway down reply, the remainder will help you achieve a balance of top and bottom tensions.

    Ensure that all is clean and free of lint and jams, this is the most likely cause....now for tension troubleshooting .......

    This solution is for tension problems...if you cannot form any sort of stitch, the issue is quite different, so please let me know if you need a different problem solved.....

    It is quite long, but just work through each section in order.

    The "knotting up" can reveal a lot. If you have loose threads on one side or the other, the tension on the opposite side will be the culprit.

    QUICK SUMMARY FIRST:
    Ensure sharp new needle,
    Thread guides and Bobbin are Clean & Clear of lint
    Set Top Tesion to 4 ....then....
    Balance Bobbin to suit.

    TOP THREAD TENSION:
    If the looping threads are on the underside as you sew, it is the top tension. Top tension ought to be between 4 & 6 (this variation to allow for the different weights of fabric in your projects).

    IS YOUR NEEDLE SHARP ?
    If you are using a needle that has seen quite a deal of work, or you suspect it may be blunt, change it for a new one !

    TOP TENSION & GUIDES:
    Make sure that when you thread the machine the presser foot is up so the thread goes between the discs and not to one side, top tension between 4 and 6, and that you have threaded through all the guides, including the last one, usually on the needle arm, just above the needle clamp.

    It may be there is lint trapped between the discs, this will keep them slightly apart and reduce the actual tension, sometimes dramatically.

    If tensions appear correct, and the thread is definitely in the channel between the discs, but still too loose and looping, try raising presser foot and remove your thread.

    Now, with a 2" (50mm) wide strip piece of fabric 8 - 10" (20 - 25cm) moistened with methylated or denatured spirit, gently insert the fabric strip and clean between the discs with a see saw / to and fro action.

    In the worst cases, gentle use of a needle to pick & remove the jam may be necessary, but be very gentle and make sure the tension is set at Zero and the presser foot is raised, (to disengage tension plates).... do not gouge or score the plates, they need a polished surface to work correctly.

    BOBBIN TENSION:
    Far less common, but if the loose threads are on the top, it is bobbin tension that is loose, it too may have lint in the spring and be giving a "false" tension.

    I would not recommend fiddling with bobbin tension without good reason, it may end up with missing small screws and spring pieces, however, you can take the needle plate off to clean
    the hook race area (where bobbin case sits)

    ...this is just 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 is a significant amount of lint, use a vacuum and small brush to get the worst.

    Then wipe all this area with a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit, especially if there appears to be fine dirty deposits....oil and lint combine to conspire against you.

    If it seems likely that you ......really ....do .....actually .....need .....to adjust the bobbin case, first check there is no lint trapped in the metal spring where the thread is tensioned.

    TOP LOADER:
    Drop-in Bobbin case will look similar to this image with the tension screw in the middle of the metalwork....

    ...the other screw at one end is holding it all together, so beware....it is not a tragedy to undo the whole lot and clean it, but very gingerly and lay the bits out in sequence and orientation, or you risk tearing your hair out !

    FRONT LOADER:
    ....this is a bobbin case from a front loading machine and works in a very similar fashion to the top loader with drop in bobbin, again, if you dismantle it, take care so you can put it all
    back properly.
    FINISHING UP
    GETTING THE BALANCE RIGHT:
    When you are certain there's no trapped lint in top tension or bobbin, set the top tension to 4 and the bobbin tension to a point where you just begin to feel resistance.

    Try using good quality thread of contrasting colours so you can more easily spot the changes.

    Set your zigzag to one width less than maximum (eg. 5 of 6 ...or... 4 of 5 etc) and sew a sample for a few inches and check the result.... adjust the bobbin tension screw very little at
    a time, perhaps 1/16 of a turn.

    You may find you are playing with this balance for some little while and if you are putting the needleplate on and off each time begin to think it cannot be correct to do this.....BUT....it is,
    and eventually, you do get a "feel" for the correct tension and then it happens quite quickly.....as a user you won't be doing it very often unless there is lint built up (or are there small hands at work around the house !?!?!)

    OTHER ISSUES:
    If you live near the ocean as we do, salt air can play havoc with metalwork inside and out, so to help minimise this, keep a few small packets of dessicant (silica gel) in your machine
    case....no case ? then make some sort of cover !

    Same applies in any damp or humid environment, keep your machine dry and dust free.

    Budget for a proper full service every couple of years (more often if heavily used) and if you don't use your machine for a few years, be aware that old oil will dry out and combining with
    dust and form a "clag" like glue (another reason for some sort of cover, even a teatowel !)

    FINALLY, A WORD ON THREAD:
    If it is worth spending the time, energy and money on making something that you would like to give lasting enjoyment......use quality thread, .......it may seem to cost a little more at the
    time, but the results, ease of use and added longevity will be worth the extra, and as a bonus, your tension troubles may be fewer and further between, because there is a more consistent diameter with good thread, and less compensating to be done by your tension plates and less thread breaks

Breaking thread and under thread is loose


Is this happening when you are free motion quilting? Do you have the right needle size, thread.

If you are talking about the thread on the bottom of the fabric being loose it is actually the tension on the top thread. The tension is too loose. You might want to check and make sure it is threaded properly and that the thread is between the tension disks. The slightest thing off will make it not operate properly.

You need to relax and take your time learning your sewing machine. Once you do that you will immediately know what to adjust or check.

Started machine quilting; first pass went just fine, rolled up quilted portion, then started machine again but the bobbin thread broke and continues to break. Took out bobbin, reset it in case, etc. N


from what you said about the bobbin thread continues to break
check for burrs in the following area--even the smallest burr can cause problems
bobbin
bobbin case
needle plate
needle could be damaged
or bad thread

Thread breakage on Juki TL-2000Qi


There are a few reasons the top thread may break.
- Check the needle plate for damage around the needle hole. Polish any burrs with fine sand paper or a needle file.
Check the hook for damage. If the hook is damaged it can cause the thread to break as it comes off the tip. Be very careful if you must remove burrs from the hook. Changing the shape of the hook tip will cause skipping problems.
Check that the top tension is not too high. The top tension should be set at a medium number
Burrs on the needle plate
Burrs on the hook assembly
Bobbin tension is too tight

I am sewing a quilt and my needle is in the right place but it keeps breaking. Please help. Also, the thread break often.


here are something you might check
upper thread breaks
1.top tension to tight
2.thread to thick or to fine for needle
3.needle not inserted correctly
4.thread caught on something-spool pin, tension area
5.needle damaged
6.needle thread is not threaded properly

Needle breaks
wrong size needle for fabric
wrong foot is attached
needle clamp screw is loose

also check for lint & pieces of broke needle under the needle plate
also the bobbin case area -take the bobbin & case out & check for pieces of broke needle

here is a tip about needle & thread
Cut 6-8 inch piece of thread of the spool you are going to use for your project
Take the needle you are going to use for the project
& insert the thread thru the eye of the needle
& lift one end of the thread to a 45 degree angle
& if the needle is the right size for the thread it will slide down the thread
But if the needle hangs on the thread you need one size larger needle for the thread

Just bought a brand new Pfaff Quilt Expression 4.0 and the top thread keeps getting shredded and breaking while doing free motion quilting. I've checked threading diagrams, changed to four different...


this is a known issue with the pfaff.....i have just bought the machine and it has thread uptake issues...thread tension issues and it comes unthreaded by itself often...leaving globs of thread on the bottom stuck in the feed dogs and under the throat plate.....then the stitches are not properly balanced because the tension gets too loose on the bobbin thread....very disappointed to find out it is a known issue with all the viking husqvarna made machines...which are pfaff, janome and viking.....sux.

Free motion quilting skipped stitches, breaking threads


Might be that you need to lower the tensions quite a bit, you'll have to juggle with top and bottom tensions though, and experiment for just this operation with the Sensormatic.

Needle thread breaks while quilting on machine frame


My friend and I both have the Juki 98Q but on different frames - we were both having problems (needles breaking, thread getting tangled) we removed the thin metal thing inside the bobbin case and have had no problems since (over a year now!).
