My machine is Janine 382.
When I try to stitch , the bobbin thread does comes up but when I continue with the fabric, it gets jammed .and the upper thread breaks.
It seems like it tries to take the fabric down along with the needle.
I have changed the needle,cleaned it ,adjusted the tension,re-threaded it several times..
Even without fabric, when it's threaded, it gets jammed.
The upper thread breaks and part of upper thread sticks to hook .
What could be the problem?
Hi, here are a few reasons it could be.1. use same thread in bobbin and needle.2. thread too old. 3. Cheaper thread frays and knots.
4.Thread and/or needle,incorrect size for the material sewn
5. Incorrect tension for the material sewn. And 6, thread tangled underneath feed dogs or bobbin. Hope this helps. :-)
The tread only breaks in the needle. what can i do . i don't get to sew anything . I tread the needle and get everything ready and start the machine and as quickly as that the tread is broken and the machine has not sewn at all.

Hm, if the bobbin thread stitch is inconsistent, I would guess it is a problem with the bobbin tension. You might try picking up a new bobbin case for our machine. Bobbin cases do wear out or get damaged or there may even be a burr somewhere that is catching the bobbin thread.
Something else to try, before buying a new bobbin case, is:
Avoid old or bargain bin threads!
Install a brand new needle (compatible with the fabric & thread).
Remove the top thread from the machine.
Try a different brand of thread.
ALWAYS RAISE the presser foot and rethread from the beginning.
Set the upper tension to the midway point and test your machine.
Adjust the upper tension until the bobbin and top threads meet in the middle of the fabric.
Check your stitch sample. Is it actually the top thread showing under the fabric, or is it really the bobbin thread. Generally, thread problems under the fabric are an upper thread problem. Thread issues above the fabric is a bobbin issue.
Try a brand new needle.
Remove the top thread from the machine.
ALWAYS RAISE the presser foot and rethread.
Remove the bobbin, check that it is wound smoothly, and install and thread the bobbin case making sure the bobbin spins the correct direction.
From that point, there may need to be some tension adjustments required.
If the problem continues, you may need to have it serviced. Perhaps there is a burr or snag somewhere that is interfering with the thread in the thread path.
ALWAYS RAISE the presser foot during the threading process and rethread the machine from the beginning. (Check that the upper and bobbin threads are threaded correctly in your machine.)
Set the tension dial to the midway point. This is a factory standard setting but each machine may vary.
Test your machine. The ideal tension is when the upper and bobbin threads meet in the middle of the fabric. If the upper thread is showing on the bobbin side of the fabric, the upper tension is too loose. However, if the bobbin thread is showing on the top of the fabric, the upper tension is too tight.
Tension is not static--whenever you change projects, ie fabric, thread, needle, you may need to test the tension on some scrap project fabric first. Get the tension adjusted before stitching the project.
Make sure you clean and lubricate your machine regularly to keep it operating--consult your owner's manual and use only good quality sewing machine oil (NO 3-in-1, cooking oil, WD-40, or old brown stinky sewing machine oil).
If you are still having issues, take it for service.
Do you use stabilizer when you are satin stitching? I had a teacher who also hooped the fabric with a spring-loaded embroidery hoop (turned upside-down under the presser foot so the fabric is flat against the needle plate) that would keep the fabric taut.
It is not uncommon for bobbin thread to rise to the top when doing embroidery, satin stitch, etc., especially if you are using lighter-weight thread than usual. You would normally loosen the upper tension so the upper thread will sink into the fabric. However, if loosened upper tension is not doing enough, you may need to adjust bobbin tension when doing embroidery, applique... You might try tightening the bobbin tension just a smidgen to get the bobbin thread to stay below the fabric. Be sure to mark the bobbin case before making any adjustments so you can return it to the original setting when finished with the satin stitch. (If you do a lot of satin stitch or applique, etc., you may want to invest in a separate bobbin case that is set up only for doing that kind of work--saves having to alter the bobbin tension frequently.)
First thing to do: install a brand new needle and clean the lint/dust from the feed dogs and bobbin area. Make sure you are using the right needle and thread for the fabric being sewn.
Second thing: remove all the thread from the machine. RAISE the presser foot and rethread from the beginning making sure that it is threaded correctly through every thread guide (consult the owner's manual). And verify that the bobbin is loaded and threaded in the bobbincase properly.
AVOID using old, fuzzy, and bargain bin threads.
Set the upper tension to the midway point between the high & low number (this is the factory standard although every machine may slightly differ). Now perform a new stitch test.
If the upper thread is creating a thread mess under the fabric, the upper tension is too loose. Tighten it.
If the bobbin thread is coming up to the top of the fabric, loosen the upper thread and retest. Sometimes the upper thread tension is not enough to prevent the bobbin thread from coming up. In that case, the bobbin tension may need to be tightened. (Search the internet for instructions for adjusting the bobbin tension. NOTE: bobbin tension adjustments should be done in micro-increments as a small adjustment will make a big difference in the result. Be sure to test after each adjustment.)
The tension is correct when the upper thread and bobbin thread meet and cross in the middle of the fabric. This will change whenever fabric, needle & thread are changed, so a sewist needs to be comfortable with regularly making upper thread adjustments.
One other thing to try is pull the bobbin thread up through the fabric before stitching and gently holding the thread tails when taking the first couple of stitches.
first thing first - thread inside bobbin should be tightly wound in. Insert bobbin into bobbin case and thread through slot and under the spring. Spring has small screw which regulates the tension. Hold the thread like yo-yo and jerk a little down-up. It should drop just a little (not run down) - that is usually required bottom thread tension,
if not, regulate with the screw. Set top thread tension 3 and sew. If still looping under, increase the top tension higher till the looping disappears. .
try rethreading the machine top & bobbin change the needle--flat side to the back of the machine, make sure the needle is the right one for the fabric being sewed clean under the needle plate & in the bobbin area for lint or theads
Hi! I've had this happen to me many times and it is so very frustrating! First, take the bobbin out and also the bobbin assembly and clean the entire area of all lint, fuzz, little bits of thread....get it as clean as you can. Take out the upper thread too. Clean and oil. Change the needle. Make sure you're using the appropriate size and type of needle and thread for the fabric. Take off the needle plate and look for any nicks or scratches. If you've got them, you can get emery cloth from a good hardware store (often in the plumbing department) and polish them out (or mostly out).
Rethread the machine, carefully following the instruction manual. Use your basic, normal settings. Using a scrap of the fabric you're trying to gather, sew a seam and see if everything works ok. You may need to hold the top and bobbin thread firmly behind the needle as you sew the first few stitches (I find this little trick helps a lot to prevent birdsnests).
To gather, sew three parallel lines of long, basting stitches (you really don't need a special foot or special settings other than to make the stitch a long one). Don't backstitch, reverse, or lockstitch either end, and leave the thread long when you cut it. Pull the three bobbin threads and the fabric with gather nicely along them.
Something to keep in mind--if you're trying to gather very sheer fabric on a zigzag machine, you may need to replace the throat plate with the zigzag hole for a throat plate with a single, small hole for a straight stitch. I've run into this situation before, and ended up using one of my antique straight-stitch only machines to do the gathering.
If you don't have a throat plate with the single hole, you might try some light weight interfacing to give some density to the sheet fabric.
