SOURCE: upper thread getting tangled in the bobbin

Always remember T-N-T. Thread, Needle, Tension. Assuming its threaded properly, is the needle all the way in and facing the right direction? These symptoms also suggest the bobbin may be in the bobbincase upside down thus turning in the wrong direction. Hope this helps.

SOURCE: problem with singer prelude sewing machine!

Firstly make sure when you thread the machine you have the sewing foot in the up position or the thread will not sit in the tension and cause this problem. Also as it is a new machine it may have a small amount of oil from transport stopping the tension discs from separating. Try sliding the folded edge of a piece of fabric with the foot up through the tension unit it may clear the oil away.

SOURCE: tangle in bobbin area, stuck needle

Please TRY the solution BEFORE giving your considered rating.




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....

4c76dc1.jpg ...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.
165ca5c.jpg 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 !

SOURCE: Upper thread knots up with bobbin thread when sewing a stich

Thread test
Test your thread quality to start, thread your machine and LIFT the presser foot (this opens the tension disks). Pull your top thread straight back. If you feel no tension no mater how much thread you pull, your thread is good. If that your machine passes that test, then let me know, we can go to step 2. If not, try different spool of thread, same test until you get a smooth pull (tip: always check your thread this way when you thread your machine)
Step 2:
Pull on your threaded bobbin thread while it’s in the machine. Does it pull smooth and even? If so, go to step 3. If not, try a new bobbin (bobbins get bent or distorted if wound too tight).
Clean thoroughly in the hook and bobbin case area and oil 1-2 drop is all.
Thread knotting on the bobbin can be a lot of things but here's some guidance:
Tension:
If the thread is loose on the bottom of the fabric, it's actually the top thread is too loose. Think of 2 little elves playing tug of war in your machine, one on toip and one underneath. If you have loops on bottom, the top needs to pull harder (tighten top tension)
Jamming bobbin case:
If it is damaged from turning out of place once, it could have rough spots on it that makes the thread hang on it, and keeps making it turn over and over. Use a finger nail board (fine sanding) and smoothall rough spots. Then reset the bobbin case taking care to put the notch in the bobbin case in alignment with the proper spot in the machine (basically 5 o’clock) when looking at the round area where the bobbin case goes.

SOURCE: SIMILAR PROBLEM OF TOP THREAD ACCUMULATING IN BOBBIN AREA

it sounds like a needle threading problem. if you have the instruction book, pull yout needle thread off the machine and re-thread as per the book ie presser foot up and make sure thread goes betwen tension discs and up over takeup lever.

to check needle tension is ok, lower presser foot and pull needle thread through needle, the needle thread should be tight enough to bend the needle a little.

goodluck,

scott.

The upper tension popped off my Necchi 3101FA sewing machine and I do not know the order these parts need to go on


Basic Tips for All
  1. Always turn the handwheel TOWARDS you (counter clockwise) as turning it in the opposite direction (away from you, clockwise) may knock the timing out requiring repair from a service center.
  2. Always be sure your presser foot is in the DOWN position before sewing. Sewing with the presser foot in the up position will cause your thread to tangle and your bobbin to jam.
  3. Change needles regularly (after 16 hours of use) as dull/weak needles can cause damage to your machine and fabric. Only use SINGER needles on your SINGER sewing machine.
  4. Always be sure you are using the correct bobbin for your machine. Class 66, Class 15 and Class 15J bobbins look very similar. However, using the incorrect bobbin class in your machine can cause damage.

Clean the bobbin case to remove the tangled thread.
After cleaning the bobbin case, insert the bobbin case properly.
If the needle is bent or broken, replace the needle.
Then, thread the upper thread properly, and continue the operation.

When sewing the thread under the material gets all tangled up. The thread is also tangled in the bobbin. At times the needle doesn't even pick up the bobbin thread, but that is another issue.


have you tried a new needle?
the needle may be bent or damaged--try rolling the needle on a flat surface to see if it's bent or not
Or the needle could be in backwards
Correct needle insertion
Correct needle insertion is mandatory for proper use of sewing machine.
Raise the needle bar to the highest point, then loosen the clamp screw to remove the old needle, place the new needle in the clamp with the flat side to the back of the machine or if using a round needle--the groove in the needle should face away from the shaft.
Push the needle all the way up to the stop or as far as it will go, then tighten the needle clamp screw

2.upper tension may be to tight--try 3 to 5

3.thread may be hanging up in bobbin case--check area for loose threads or lint

4.also clean under the needle plate for lint & loose threads

check to see if the thread has come off the thread take up lever

There is something wrong with the bobbin. When I sew it catches somewhere and bunches thread up underneath


Does this only happen when you begin sewing????? Make sure your upper and lower threads are long enough for you to hold them.......lower your pressure foot and don't release the threads until you have sewn several stitches into the seam. If you don't hold the threads when starting a seam...both threads often get pulled down into the bobbin area and cause a big tangled mess. Hope this helps.

I have a necchi sewing machine. How and where do you insert the bobbin in model 525fa


if you have a snap in sewing table remove it first
at the bottom in front of the needle plate area is a bobbin case door
when you open it there is the bobbin case & also should be the feed dogs
always keep the bobbin area clean of lint or loose threads
take note of how the bobbin case is inserted in the bobbin area,, see where the thread tail is at on the bobbin case
then make sure the bobbin is wound correctly or it can cause sewing problems
reinsert the bobbin into the bobbin case the same way it's removed

I also have a necchi sewing machine, the base of your is like the base of mine, if you need a picture of inserting the bobbin,, send me a comment with your email address & I will send you a picture of the threading the bobbin case & inserting it
