How do I fix top tread breakage on a white model 935

My top thread constantly breaks after about 3 stitches. I have done the maintenance that the manual tell me but it hasn't helped... My mother in law is planning on coming over this week to get it working, and I sure would like to get it done myself, if you know what I mean.. :)

The top thread breaks

1. the needle thread is not threaded properly

2. The needle thread tension is to tight

3. The needle is bent or blunt

4. The needle is incorrectly inserted

5. The needle thread & the bobbin thread are not set under the presser foot when starting to sew

6. the threads were not drawn to the rear after sewing

7. The thread is either to heavy or to fine for the needle

8. Try a different spool or cone of thread

SOURCE: WHITE Jeans Machine model 1475 thread tension problem

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 consistant diameter with good thread, and less compensating to be done by your tension plates and less thread breaks !

SOURCE: thread wont overlock

When the thread breaks too often, try these, that goes for all sewing machines
1. Replace the needles,
2. Loosen slightly the tension of the needle threads.
3. The top threads are to thin,
4.The sewing (rotary) hook or looper, has burs,
5. Wrong threading

SOURCE: Stitches not forming!

Good Morning,

A few things to try:

  1. Loosen the needle screw, make sure the needle is fully up in the needle hole and re-tighten the screw. Vibration can sometimes cause the needle to slip...and the needle not fully inserted can cause this problem.
  2. Make sure the bobbin is turning the proper direction. If your machine has a standard bobbin case that comes out of the machine, turn the case so the bobbin is facing towards you. Pull the thread tail and make sure the bobbin turns clockwise. If it's turning counter-clockwise, flip it over and try your machine again. If your machine has a drop-in bobbin, double-check your particular machine instructions to make sure it's going the right direction (clockwise or counterclockwise depending on the machine).
  3. Make sure you have tension on the upper thread. Do this by lowering the presser foot (make sure the thread tail is NOT under the foot) and give the thread a tug. You should feel tension on the thread. If not, the thread isn't fully down in the upper tension disks. You should be able to give it a further tug to pull it down into the disks. No tension on the upper thread can cause the stitches to not form.
  4. If none of the above seems to help, you'll need to get your dealer involved (provided you purchased your machine from a sewing machine dealer). They can determine if it's just something happening during threading or if the machine is out of timing. They are there to help you before AND after the sale and should be willing to take care of whatever is happening.
  5. If you did NOT purchase your machine from a dealer, and the store you purchased from does not have a sewing machine technician, we would suggest that you return/exchange it for a new machine and see if the new machine has the same problem (most department/big box stores that carry machines have a very liberal return policy since they do not have personnel dedicated to sewing machines).
  6. If the new/replacement machine has the same issue, we would suggest you return it (no sense frustrating yourself) and perhaps find a local sewing machine dealer to purchase a machine from. Authorized sewing machine dealers are geared towards providing machines and service (before and after sale) and are worth the extra $ for the peace of mind and knowledge that you'll have someone local to call on for help.
Best of luck with your machine - we hope it's something minor and you're up and sewing soon! Don't hesitate to reply to this post if we can offer further help, ideas or suggestions.

Happy sewing,

SOURCE: Singer CE-150: Constant error messages, thread breakage, etc.

Check the sensor at the top of the machine. It is where the thread passes through the plastic "u-turn". Check to see if the wheel turns when you pull the thread through the machine. The wheel has a red marking on it. If the wheel isn't turning when you pull the thread, it may not be sensing the threading correctly.

I hope this helps. God bless you!

SOURCE: top thread keeps breaking

This sounds like a backwards needle. Take out the needle and when you re-insert it back in, make sure that put the flat side to the back.

Where are the oiling points and what would make the threads constantly break


Depends on your make & model machine. Newer computerized machines require little or no oiling. Consult your owner's manual AND use only good quality sewing machine oil.

When sewing it skips stitches also the thread keeps breaking.


Remove the thread from the machine.
Install a brand new needle.
RAISE the presser foot and rethread the top thread.
Verify the thread path is correct.
Load and thread the bobbin case & install it. Verify it is correct.
Set the top tension at the midway point.
Re-test your stitch.

Remove the thread and rethread. Usually, thread breakage occurs when the thread is not following the thread path. However, there could be other reasons:

My bobbin and thread are constantly breaking. I have the correct thread to needle, but I don't even get one stitch before both break. Tension is on auto; should it be less or more?


is the needle in the holder the correct way ( groove in the needle facing the thread )
Is the needle eye the correct size for the thread in use

remove it from auto tension setting and adjust it your self
make sure that the top thread is between the tension plates and not around the thread behind the plates
the thread tension is close to correct when you need a bit of a pull to pull it along to the needle
is the method of threading to the needle correct as any areas where the thread reverses direction will cause it to break
what do mean that the bobbin is constantly breaking or is it the bobbin thread that is breaking
have you got the thread down the case slot and under the flat spring correctly
the bobbin has to be inserted into the case in such a manner that when the thread is pulled , it flows down the slot freely as the bobbin turns
if the direction is wrong , the thread has to move across the sharp edge of the slot and will cut easily

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.

Constant thread breakage. I have a singer futura CE-150 embroider machine. IT is brand new never been used just got out of the box. I can get about 100 stitches before breaks. I am using 100% ployester...


Well it sounds like you're using a decent thread, that can often be the issue. Just wondering if your top thread is too tight? Might be worth fiddling with the tension to see.

Another thought could be look at the trouble shooting guide in your manual as most have one, but my gut instinct would be the tension.

1 Answer

Bobbon thread is too losse /thread breaks no


Clean out the bobbin area.

Thread the machine with the presser foot up. This opens the tension so the thread can enter. Threading with the foot down closes the tension and the thread cannot enter as it should. When you sew, the top thread is loose and cannot properly connect with the bobbin thread to form a tight stitch. The stitching does not hold and pulls right out.

Thread breakage - top thread? Check the thread spool to be sure there aren't any nicks to catch the thread.

When the thread breaks, check the spool pin to see if the thread is unwinding too fast and wrapping around the pin. Thread nets can help stop this. You can find them at sewing machine dealers.
