Question about Janome Sewing Machines

2 Answers

My Heart Truth 2008 sewing machine was sewing fine when the top thread got caught between the bobbin case and the machine - and it has been producing nothing but knots ever since. I cleaned the lint out of the bobbin case area and changed the needle - what do I try next?

    The answer I received was generic thread tension problems. My thread is getting caught in the bottom of the machine. It wraps around the bobbin case, but doesn't make it all the way around. Then without completing the first stitch, it wraps the next stitch around the bobbin case - and gets stuck again (and again and again). it was working fine with the tension settings as they are, with the same thread and fabric one day - and just producing knots the next.

    Thank you for not giving me a "canned" answer!



    I did know bobbins are different - and I "hid" my singer bobbins when I bought the janome. I'm sure I have the right one in the machine. I did not know they could go bad!



    I also knew all thread isn't equal. I never buy the 100% polyester thread - and can get rather picky about it. My time is worth more than the pennies the cheap stuff saves. Could a spool of thread "go bad" in the middle??



    I was expecting something like "make sure this screw is tight" or "drop some oil here". I hope these easier suggestions help - I will test them tonight!



    Thanks!

    Well, I changed the bobbin and put in different thread in the top. Played with a couple different stitches - a couple tried to knot - and just kept the machine going until it was consistent. THEN I put the "old" bobbin back in - and it worked! THEN I put the same "old" spool of thread in - and it worked! So - I still don't know for sure what the problem was - but I'm happy again!! Thank you for your help - and the education about bobbins!

  • Assuming you threaded your needle right I would start with looking at your bobbin. They do go bad and you could have that thread to tought around the bobbin. If you have a spare bobbin then string a fresh bobbin, and pull the old one out and replace with the new bobbin.
  • Also note that cheap thread will mess with a sewing machine something awefull. Had this Walmart thread one time that just tore and knotted. New quality thread took care of that.
  • Also bobbins are not a one size fits all. Make sure to use the same style bobbin every time. Again, as with thread, cheap bobbins are not always netter.

    • Sure, thread can go bad just from storage. Thread is spooled, naturally, and can get become tangled or over taught further inside the spool from undo stress. Let me know how it works out for you.

    As for how bobbins go bad, they spin constantly but are not on bearings like a car wheel. So the inside of the bobbin that sits on the shaft begins to open up and warp and gap. When a bobbin does this it does not feed the needle properly, because its not seated properly, and you get faulty sewing. Often times you can't see with the bare eye this has happened. Trial and error is the only way. And bobbins come in wood and metal and different sizes. The wrong one, even the right one but cheap, will or may not work.

How do I adjust tension on a Necchi Lydia 510 sewing machine?


loops under fabric means top tension needs to be tightened
try cleaning the top tension dial with some unwaxed dental floss and see if that helps. if it doesn't then the tension dial may need to be replaced
also check to make sure the spool of thread is not getting caught on the spool holder
also try a new needle--one that is correct for the fabric being sewed

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


Bobbin thread breaks


1. There is a right way & wrong way to insert the bobbin in the case --when you insert the bobbin in if it doesn't stitch correctly turn the bobbin over see if that helps or bobbin case is not inserted correctly


2. Lint has collected in the bobbin holder


3. The bobbin is damaged & doesn't turn smoothly


4. Lower thread tension is two tight

if the sewing machine has a top loading bobbin, you may have to have the sewing machine checked to see if there is something wrong with the bobbin case or the hook and hook race.
I suggest try a new needle--one for the fabric being sewed
also try another bobbin
rethread the sewing machine top and bobbin, using every thread guide.

Toyota 9400 Sewing Machine top thread caught between bobbin casing and spring causing jam


it would be a very good idea to have the machine serviced since
someone gave the machine to you, and having the bobbin
case replaced would be a good idea and having the spring
checked would be good too.

I am sewing scout badges on a uniform and when I sew there is a bunch of needle thread bunched up on the bottom (the top looks fine). And the needle thread gets all caught up around the bobbin.


Clean out the bobbin area if there are any thread tangles there.

Refer to the maintenance section of the manual - see the configuration of the bobbin case and shuttle race? The bobbin case as an extending arm and the race a notch. When inserting the bobbin case into the shuttle, turn the handwheel so the needle is at it's highest position. Then lift the lever on the back of the bobbin case and insert the cast into the shuttle, arm pointing straight up toward the bed of the sewing machine.

Now thread the machine with the presser foot up - always - and see if the tangling stops.

When you forget to lift the presser foot before threading the machine, the tension control does not open to capture the thread. Then when you begin to sew, the top thread has no tension, and the bobbin thread, which does have tension, pulls the top thread to the bottom in messy loops.

You need to sew the first stitch slowly. Lower the needle by hand and take up carefully. Pull the needle thread up and the bobbin thread should be caught in the formed loop and come with it. Pull them both to the back of the machine and sew.

Other than your machine being out of time and needing service, following are suggestions to try:

Be sure to use the correct type of needle for the thread and fabric you are sewing, ie sharp, top-stitch, embroidery, universal, or microtex for woven fabrics and ball-point needle for fine knits.

AVOID old or bargain bin thread.

Remove the top thread from the machine.
ALWAYS RAISE the presser foot and rethread from the beginning.
Check that the bobbin is turning the correct direction in the bobbin case and the bobbin case is properly threaded.
Set the top tension to the midway point.
Re-test your machine and tweak the top tension so the top and bobbin threads meet in the middle of the fabric.

If the thread continues to hang up, take your machine for service and adjustment.
