    Check the timing of the needle to the hook. HERE is a guide to generic principles of Timing



    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

SOURCE: Bottom (bobbin thread) makes loops

I don't have the same brand as yours, but on my machine there is a little screw on the bobbin case that you tighten to increase the bobbin tension. If you've got one, turn it 1/8 to 1/4 turn at a time.

SOURCE: Bobbin thread not catchinig Kenmore model 385 12912890

Christytn,

I am going to guess that you have the bobbin thread facing the wrong way. When you
put it in the case, open part facing you, make sure the thread is going clockwise.
That should fix the problem.

SOURCE: viking husqvarna classica 100, thread tension

I suspect you are correctly threading the machine but the timing of the needle and bobbin hook is off. When the threaded needle goes into the bobbin area, a pointed hook grabs the thread and loops it with the bobbin thread. Something is catching when the needle starts to come up that is not allowing the bobbin thread to be pulled back through the needle plate opening by the upper thread. With machine threaded and bobbin in place, have the bobbin area open if possible and watch the thread interaction when the needle goes down. To set the hook/needle timing, normally covers have to be removed. Suggest taking it to an authorized Husqvarna Viking dealer for service.

SOURCE: Bobbin thread will not stitch.

Have you had the machine serviced since you purchased it? This is something that should be done at least once a year.

Take the machine to a certified Singer dealer and explain what is happening. There may or may not be something that needs to be adjusted.

Your warranty is still in effect, but is now limited. Attempting to repair it yourself or having someone who is not a Singer dealer repair it will invalidate the remaining warranty.

Refer to page 15 of the manual - http://www.singerco.com/accessories/manuals.html

Before changing the tension settings, be sure to thead the machine with the presser foot up as this also has a tremendous effect on the tension and formation of the stitch.

The directions are very vague about how to thread the bottom bobbin. I have no idea how this is to be done or how the needle will pick it up. Help Please!


you don't thread the bobbin as such
wind sufficient thread on to the bobbin (use the rewind section of the machine )
place the bobbin in the bobbin carrier in such a manner that the thread unwinds anticlockwise
take the thread and pull it around the edge of the bobbin holder until you reach the slot in the holder
pull the thread down that slot and under the flat spring plate at the bottom of the slot
That plate controls the tension of the bottom thread
pull out about 5" of thread and while holding the thread put the bobbin holder and the bobbin into the machine making sure that it goes right in and clicks in place ( turn it to achieve the click
The needle should be fully up for this procedure
now thread the needle and hold the end of the thread while you hand turn the machine in the sewing direction
the needle will go down and if not on the first time will on the second time pull up the bobbin thread
pull that bobbin thread up and place it along with the needle thread under the foot plate and out the back comment if that doesn't work as there may be a bigger fault that can be fixed

How do I fix the bottom bobbin thread


THE BOTTOM AND TOP THREADS ARE IN A TUG OF WAR. WHEN THE TOP IS TOO LOOSE THE BOBBIN WILL BE PULLING HARDER THAN THE TOP THREAD SO A GREAT DEAL MORE THREAD WILL END UP ON THE BOTTOM. TO CORRECT THIS YOU INCREASE THE TOP THREAD TENSION. IF THE TOP THREAD IS PULLING HARDER THAN THE BOTTOM THEN A GREAT DEAL MORE BOBBIN THREAD WILL END UP ON THE TOP. TO CORRECT THIS YOU WOULD LOWER THE TENSION ON TOP.

How do I change the bobbin in a Janome sewing machine?


There is a small plastic plate where the needle goes down through the foot, remove this cover and you will see the bobbin. Remove the bobbin and refill or selecting another bobbin turn it so that when you pull the thread the bobbin turns anti-clock-wise, slip the bobbin into the black plastic casing, pulling the thread towards the small red arrow at the bottom of the casing, slip the thread between break in the silver metal sleeve pulling it to your left between the 2 pieces of metal this is where the tension on the thread is. You have now changed your bobbin. With the plastic plate still off, hold the top thread with your left hand and with your right slowly turn the wheel, this will send the needle (holding your top thread) down into the bobbin casing and will pick up the bottom thread, pull on the top thread and bring the bottom thread up through the hole in the plate. Replace the plastic plate and recommence sewing. Good luck

Bottom thread bunches


try changing the needle
rethread the machine top & bobbin
clean under the needle plate & in the bobbin area for lint or thread
make sure the bobbin is inserted correctly into the bobbin case
if none of these suggestions help then it's possible that the machine is out of time & needs to be serviced

Bobbin thread keeps knotting


1. Do you mean that there are knots in the bobbin thread?
2. Is the bottom thread in your stitching looping and knotting.

If yes to 1. you need to rewind your bobbin fresh, and keep slight tension on the thread reel that you are winding it from. Put the handle of your scissors into the top of the reel to apply a gentle pressure while winding. Keep your eye on the bobbin as it winds and give it a nudge with a finger tip to ensure it winds the bobbin evenly top, middle and bottom.

If yes to 2, then you need to check your bobbin threading, is the thread even under tension. Is the bobbin tension set correctly. Break out your manual and revisit this to ensure it is set correctly.

Bottom thread too loose; tried rethreading top thread, cleaning bobbin case, refilling bobbin, changing needle, adjusting top tension


Check for correct bottom thread tension.
It's provided by a flat spring on the bobbin holder.
When the bobbin is correctly installed, pulling on the thread
should meet with slight resistance, and the bobbin should spin without
trying to jump out of the bobbin holder.

I have a 7570 and cannot get the tension the bottom thread is loose and can be pulled right thru I checked the top and adjusted the bottom and nothing seems to change.


When you thread your bobbin in the bobbin case, hold it only by the thread. If the bobbin and bobbin case fall, the tension is too loose. If this is the case, turn the bobbin tension screw 1/4 turn until the bobbin and bobbin case do not fall when only holding by the thread. The top tension should be set between 4 and 5. The best way to see which one needs to be adjusted is to do a zigzag. If the thread is pulling more on top and your top tension is set between 4 and 5, the bobbin tension is too loose. If your top tension is set between 4 and 5 and it's pulling on the bottom, the bottom is too tight.

Brother ls2125 bobbin not picking up thread


OK...I have an old singer (from 1964) so I am not sure whether you can do this...

I thread the upper thread as directed.

I stick the bobbin in the bobbin assembly as directed.

LEAVING THE SLIDE DOOR OPEN...I, by hand turn the wheel on the right hand of the machine counter clockwise (towards me). I want the needle go down. The thread from the upper part will enter the bobbin area and will form a loop that goes OVER the top of your bobbin to catch the thread from the bottom.

I keep turning until the machine has complete a cycle where the needle has started from the highest point, dropped to the lowest point (thus forming the loop that passes over the bobbin) and returns back to the highest point).

At this point you will notice that the thread is coming for from the bottom of the machine..I use a scissor to pull the the ends of the thread through. To the top. There should be two ends, one from the top thread, one from the bottom. If you dont believe me..jsut use a bobbin with a different color of thread...you will see what I mean..there will be two threads...one the first color and one the second color.

Good luck!!

Bobbin thread breaks


Make sure your bobbin thread is turning clockwise as it sits in the bobbin case. There is a screw on the outside of the bobbin case you can turn with your thumb slightly to adjust tension. If you dangle the case from the thread and give it a light ****, it should move down slightly when doing so-an indicator of good bobbin tension.
