Bobbin thread not being picked up.

I saw your comment on FixYa.com about a brother sewing machine not picking up the bobbin thread with the top needle. Do you have a solution for this? Do you know why this is happening? You can email me at ashleetodd@hotmail.com. Thanks for your help!

    I have a Janome QC machine and it will not pick up the bobbin thread. The repair man says it is the timing AGAIN. I am finished throwing money at this machine.

  • wabb1t Oct 26, 2008

    This is my first sewing machine and I'm not sure if I am making a basic error. I have put the bobbin in correctly I am sure but when I put the needle down it does not pull up any thread from the bobbin. the bobbin does not move and I can see bits of metal moving but there is no movement of the bobbin thread. Help !!!!!

its the problem of the timing belt in your machine its extra loosen or extra tightned or is slightly came out of its position or finally broken.
as the machine is proper just missing the proper speed as it should be .
it is running continuosly as you stated.
check the timing belt and make it proper if its worn out and needs replacement this is how its done

There is an adjusting screw on the right side of the machine head. Follow the motor bracket to the machine head and loosen that big old screw or bolt which will raise or lower the motor giving you slack to remove or replace the belt.

feel free for further queries
thanks

The top of the machine is not threaded correctly. First raise the presserfot then rethread the machine. Bottom looping is usually caused by a lack of top tension. There could allso be a bur on the hook.

SOURCE: bobbin threading

You may have put the timing out, however, try this before you despair too much......

Ensure the presser foot is firm enough for the fabric you are using and that it will not just pull through easily by hand with the foot and feeddogs together (as the needle ascends), or things will not proceed, and you will be stitching in the same spot.

Generally a setting of 3 seems to work for general purposes, but if you are using very light or very heavy fabric, a sample is always a good idea before you start in earnest....also match the needle to the work for best results.

Ensure that all is clean and free of lint jams....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: needles keep breaking & bobbing wont feed thru

First try taking your bobbin case right out of the machine (not sure if this model has a top loading or front loading bobbin, but your manual will help you here) and floss out the tension slot with a piece of strong thread. Don't use waxed dental floss, but non-waxed would work okay. (The bobbin case is the piece that the bobbin sits in.) Look around while you have the machine open and remove any fluff and thread you can see - TURN MACHINE OFF BEFORE DOING THIS! Replace bobbin case. Replace bobbin and make sure it "clicks" into the tension slot.

Then unthread the top of the machine, clean the tension disks by passing a folded dollar bill (or any paper money, depends on what country you are in) through the disks in the direction you thread the machine. Do this several times. Re-thread making sure you follow the correct thread path.

Make sure the needle plate is on firmly.

If after all that it still won't work, I'm sorry to say that it sounds like you have a misaligned needle bar. This commonly happens after you have a major thread snaffoo and needle breakage. The needle gets caught in the thread knot, pulls to the side and breaks but if it gets seriously caught it can pull the needle bar out of place. You cannot put the needle bar back in place yourself - it's a job for the workshop. Don't sew on your machine until it is fixed. The noise you are hearing is likely to be the needle striking against the needle plate or even the bobbin. Your timing will probably need re-setting too and this needs to be done by a qualified technician.

If you really need to sew before you can get your machine into the workshop, and if you can move the needle position on your machine by pressing a "sideways" button of some sort, you could try to get the needle in the centre yourself using this feature. This will not help if it is the timing that is the major problem.

SOURCE: Top thread won't pick up the bobbin thread

re insert the needle, maybe you did not put the needle up as far as it is to go. Make sure the flat side of the needle is to the back of the machine. Without any thread in the machine hand turn the wheel and look to see if the hook of your bobbin would/could catch the thread (to see if timing is right)
then thread the machine and hand turn the wheel and see what it is doing.
Your timing might be off, but I do not think that is likely. Though it is possible that when the needle fell out, it hit something hard, broke, and pushed the machine out of timing. then you need to bring it in.

Try installing a brand new needle (verify it is installed correctly). If it still does not pick up the bobbin thread, the needle/hook may be out of time, requiring service.

try changing needles
clean under the needle plate & in the bobbin area for loose thread or lint
make sure the bobbin is inserted into the bobbin case correctly--if the
machine won't pick the thread up from the bobbin correctly take the bobbin
out of the case & turn it around & try it that way.

The top thread is not picking up the thread from the bobbin. Is there an adjustment that needs to be made to solve this problems?


Try a new needle, installed with the flat side facing the rear of machine, make sure that you have a 3-4 inch tail on top and bobbin thread. Hang on to the top thread tail and slowly turn your handwheel towards you and watch it pick up the bobbin thread. If that fails, it may sadly be your timing is off and needs professional service.

The machine stopped sewing, the top thread doesn't pick up the bobbin thread, even when I just installed a new bobbin and try to just run the machine by hand to pick up the bobbin thread.


Have installed your bobbin right? By this, I mean drop the bobbin in but make sure that you pull the thread through the tension spring by putting your finger to hold the bobbin in place, then pull on the thread to get the tension. Let me know if this works.

My needle won't pick up the bobbin thread


My sewing machine is a Brother LS1217, well actually it is my son's, and he uses it very seldom. I went over to put in a new needle and I cleaned it top and bottom, put in a new bobbin, and a new needle and the needle won't pick up the bottom thread. What am I doing wrong? Please help me!! It has to be something simple, as this is such a simple machine! roseandjimmy@yahoo.com
