One reason could be the thread tension. If it is more the thread will snap. Please loosen the thread tension and run it. It should not break.

Royal Series, Necchi, Model # 80331763 bobbin does not take up thread properly. No manual unsure if i am threading it correctly.


You can get Necchi instruction manual from Necchi website: http://www.sewusa.com/Sewing_Machine_Manuals/Necchi_Sewing_Machines.htm". Makesure the needle is in the machine correctly- all the way up into the needlebar, make sure that it is threaded correctly, etc. If this all checks out ok,take the bobbin case out of the machine. There are two ears on either side ofthe bobbin case- turn the left one to the left and the right one to the right.Remove the silver ring, and inspect the piece of metal that the ring came off of(looks like a circle with the top cut off). You have to locate the hook whichis the piece that looks like a half moon inside the big round metal piece.Locate the tip of it, turn the hand wheel toward you until the needle is in thelowest position, at this point the tip of the hook should be flush with top ofthe left side of the cut off circle. Checkwhether underneath thread is looping on the fabric. If so then you've mis-threadedthe top, probably haven't raised the presser foot when threading so you can getthe upper thread into the tension. You need to thread the upper part with thepresser foot up. (You can put it down to thread the needle.)

Not picking up thread can be several issues, like bobbin is miswound, bobbincase isn't snapped in properly, you're using the wrong type bobbin, machine isout of time, needle is bent or burred, machine is dirty and in need of dustbunny eviction and a little oil but most of the time the issue is once againmisthreading: sewing machine needles have a front and a back and they have tobe placed in the needle holder correctly. In that case your manual is needed, take all the thread offthe machine (yes, spool off the spool pin, bobbin out of the bobbin case), pullthe needle plate and clean your machine thoroughly, using brush and vacuum (notcompressed air) and oiling per the instruction manual. Put it all backtogether, putting in a 80/12 needle, correctly oriented. Hang on to theneedle thread when you fetch up the bobbin thread.

Each and every seam you start is going to be done this way:
1) Pull the tail of the top and bobbin thread behind the presser foot
2) Put the work under the needle and use the hand wheel to lower the needleinto the work
3) Drop the presser foot
4) Holding the thread tails behind the foot, take a couple of stitches.
5) Drop the thread tails and sew normally. Hope this will help you. Good Luck.

Thread gets under needle while sewing. needle then cuts thread. is this a bobbin tension problem? thanks!


Hi. My guess would be no. Sounds more like an upper or needle thread tension problem than a lower or bobbin thread tension problem. Your trouble could also be the thread take-up lever was missed when threading the machine. Trace the thread path to make sure the threading is correct. Is this an embroidery machine? If not, were you trying make a darning stitch? Perhaps with the foot raised? Keep in mind that raising the foot loosens the upper thread tension.

Wife has Kenmore 385.12314. Regular use. Normally cleaned and oiled. Needle goes down, but bobbin thread doesn't catch. Needle at bottom of stroke and "half moon" is on top, needle...


Make sure the needle is in the machine correctly- all theway up into the needle bar, make sure that it is threaded correctly, etc. Ifthis all checks out ok, take the bobbin case out of the machine. There are twoears on either side of the bobbin case- turn the left one to the left and theright one to the right. Remove the silver ring, and inspect the piece of metalthat the ring came off of (looks like a circle with the top cut off). You haveto locate the hook which is the piece that looks like a half moon inside thebig round metal piece. Locate the tip of it, turn the hand wheel toward youuntil the needle is in the lowest position, at this point the tip of the hookshould be flush with top of the left side of the cut off circle. If this is notso, your machine needs to be re-timed. If that is the case, I would need to seea picture of the bottom of the machine so that I am able to determine whatneeds adjusting. Make sure you're turning the hand wheel in the proper direction-- the proper direction isthe one that will feed fabric forward under the presser foot.

Make sure the needle is facing in the correct direction -- stitches don't form,or skip badly when the needle is turned around.

Put the bobbin in the bobbin case (right way around) leaving a 2-3" tail.

Thread the top of the machine correctly, leaving a 3-4" tail afterthreading the needle.

Hang on to the end of the upper thread, and use the hand wheel to drop theneedle... continue to turn the hand wheel to raise the needle. Pull on the endof the needle thread and a loop of bobbin thread should come up.

Hold BOTH threads behind the presser foot when starting a seam to preventthread jams.
Hope this will help you. Good Luck.

The tension of the thread on top and bottom is not equal. How do you adjust the bottom thread to make it equal to the top?


Hello

First locate the sewing machine tension gauge. Sometimes its called a knob or a button or found on your Touch Screen if you have a computerized machine. Refer to your manual if you can't find it.

Either your needle thread is too tight or your bobbin thread is too loose.

First check that your bobbin thread hasn't slipped out of its tension spring in the bobbin case.

If the bobbin thread is correctly threaded through the tension spring, then decrease your needle tension by 1 number. Test by stitching several inches on your small quilt sandwich. Keep decreasing the tension until no needle thread is visible on the quilt top.

If sewing machine tension problems occur during the middle of a quilting session, again, first refer to the checklist above. Once you're satisfied that your sewing machine is threaded properly and your needle is not the culprit, then adjust the tension as outlined above.

If you have just started testing your quilting thread choices and you are using different threads for the needle and bobbin, you will in all probability make adjustments to your tension.

Make a small quilt sandwich from the materials used in your quilt to make this sandwich. It doesn't have to be pretty or even pin basted. It should be just big enough to test some of the stitching you plan to do on your quilt.

I have needles snapping and bobbin tangle


Try to repair in this order.

1) Your machine likely needs oil. Especially put a few drops of oil on the outside edge of your bobbin holder.

2) Try replacing your needle if you have some spares. If you are using a decorative thread (metalized) use a needle with a teflon lining on the eye (called metallic thread needle).

3) Try buying a better quality thread. Do not use generic thread in a sewing machine (i.e. "made in cheap country" with no brand name)

Please rate me..

Bobbin not threading through, spool thread is gathering in bobbin catch and not sewing - just clumps of thread


It would appear to be threaded wrongly. Pull all the threads out, check the visible upper tension discs for broken threads then re-thread top and bobbin, making sure the pressure foot is up when you re-thread. Bobbins should normally turn clockwise when the tail of the thread is pulled. Make sure thread has gone under the tension spring.
Oddly enough, a blunt needle can occasionally cause this problem so if all else fails try changing the needle. Good luck

Sewing machine won't pick up bobbin thread


open the bobbin case and see if the hook is turning, if it is it is just a timing problem with the hook and needle, if it isn't tuning you may have a broken gear or timing belt.....It eill need to be looked at or adj by someone who repairs them....Daniel
