Upper thread on embroidery machine jamming machine, and ending up with a bird's nest in the bobbin area.

Took bobbin area apart and removed loose threads, etc. Looks like top thread won't clear the little metal 'arm' at the upper right of the bobbin shuttle. Also, stitch plate won't sit flush on the right side of the deck when I put it back on. Any thoughts? Tia

Upper threading is wrong. Thread could be catching on the end of the spool. What machine are you using?

SOURCE: upper thread getting tangled in the bobbin

Always remember T-N-T. Thread, Needle, Tension. Assuming its threaded properly, is the needle all the way in and facing the right direction? These symptoms also suggest the bobbin may be in the bobbincase upside down thus turning in the wrong direction. Hope this helps.

I had this problem and it all came down to using the wrong backing. I kep trying to use tearaway on everything but WRONG. Using the proper backing corrects most problems. Good Luck!

Have you checked the top thread is correctly placed in the spring of the bobbin case?

SOURCE: Bobbin problems

Are you using a size "A" (Class 15) bobbin? If you are using pre-wounds and they are not this size... they will jump around alot. The size of an "L" is very similar, but they are not as tall (height off the table when laying flat on the round side... like when sitting in the bobbin case.) There are tricks to using the thinner bobbins... See if you have a "taller" size "A"/Class 15 and if that corrects the trouble. tjsews2008@gmail.com

Why is the bobbin thread bunching up?


if your saying that your bobbin thread is balling up under the platen plate , this is a sure sign that your top thread tension is not correct and there isn't enough tension to pull the bobbin thread up from below

When pulling my bobbin thread thru to top my upper thread doesnt go all the way around the bobbin case then it hooks on the little metal arm on top bobbin case on my PE700


The part that holds the bobbin case moves around it after catching the upper thread. Check it and see if it is not working as it should. I wonder if the bobbin is not in far enough.

Tangled thread on wrong side of fabric, I did the remedy as per manual but problem still exist


Unthread the machine fully. Remove the bobbin. Is the bobbin thread the same as the top thread? Is it a Quality thread (yes, cheapie thread can give big issues!!) Do you have several different threads wound onto the bobbin?? Is the bobbin thread wound on quite tight? If you push your finger nail into the thread wound onto the bobbin, it must not feel soft or spongy. Check if there is any roughness / burr on the any part of the shuttle hook. If so, remove it with 800 grade wet and dry abrasive or similar. Put in a NEW needle as per user manual specs (not a 'new' one you used before 'just for a little bit'.!) REPEAT - put in a NEW needle - amuse me!!. Place the bobbin into the bobbin holder (the CORRECT direction - yes there is a Right and a Wrong direction!), thread it ready to put back into the machine. BEFORE you do, hold onto the thread tail and let the bobbin and bobbin case dangle. Thread should slip thru when you give a gentle pull upwards. If no slip, loosen the tension on the tension finger a LITTLE. If it slides down easy, tighten it a little. Fit the bobbin into the machine. Lift the presser foot (this releases the top thread tension discs) Check there are no bits of thread or fluff between the tension discs Rethread the top thread - check the thread path is 100% correct. Hold onto the end of the needle thread and draw up the bobbin thread. Hold both threads, start to sew - check the result. Tip : If you use a different color bobbin thread (same brand etc etc) it will help you to see more easily what is going on. You should be seeing some of the bobbin thread color on the top side of the sewing. If not, INCREASE top tension a little - retry.If there is a lot showing, decrease top tension. Good luck

Bunches of threads on the bottom


You didn't give the brand, but if it's any of the older, non computerized machines, your problem is most likley in the tensions.
Loopies (tangles or nests of thread) on the bottom means upper tension too loose (or bobbin too tight).
Let's do the bobbin first...once it is set...99.9% of loopies on the underside are a problem with upper tension.
This is for bobbins that load on the front/side of the machine.. Take out the bobbin case...check the area (hook/race area) that the bobbin goes into for lint, tiny thread pieces, etc.). Now, most of this type of bobbin loads into the case with the thread going counter clockwise (when you are looking at the open side of the case), insert the bobbin in the case, and pull it through the hole/slott in the side of the bobbin case. To test for proper tension:
Lay the bobbin case in the palm of one hand, pull on the thread coming off the bobbin case. The bobbin will gently lift off your hand & if you wiggle the thread, the bobbin case should slowly drop about an inch at a time. If it's too tight, loosen the Larger (closest to where the thread comes out) screw on the side of the bobbin case about 1/16 of a turn...tiny bit...retest. Once that is done try a test stitchout. Remember to hold onto the bobbin & top thread for first few stitches.

If you still get loopies on the bottom...tighten the upper tension...it should be set between 4-5 for regular sewing.
Make sure the needle is in properly.

For a drop in bobbin...adjusting that tension is harder. You take the face plate (needle plate, the plate covering the sewing area of the machine) off and remove the bobbin case...First...look at the case in the machine...there is a little lip sticking out, usually at the bottom right corner of the open area (closest to you)...this is where you need to have the little lip when you replace the bobbin case.
Remove the case...check under it and inside the machine for lint/dust/threads & using a small paint brush (I use a childs tooth brush sometimes), clean the lint out. Now check the bobbin case for lint, especially where the thread fits..look at the inside of the case, you will see a little flat metal thing with a slott in it...make sure no lint in that slott. I use a pin to remove lint from there. Reinsert the bobbin case, rethread it all, (bobbin goes counterclockwise). Put the faceplate back on & test the stitches...still loopies with the upper set to between 4-5? Then you will remove the faceplate, remove the bobbin case & loosen the screw on the outside about 1/16 of a turn (these are usually covered in a colored coating) and retest.
I know that most home machine makers say not to adjust the bobbin..but that was back when you had one size thread...now we have many, many sizes and types of thread, so adjusting the bobbin may be needed sometimes.
Rule of thumb is:
loopies on underside...tighten upper tension
loopies on top...loosen upper tension.
But, like I said...with all the new threads..sometimes you have to adjust that bobbin.

Pfaff varimatic 6091 sew a rag quilt with jean and flannel,I can't get my tension right it seems to be funny on the bottom stitch,where shoulf the top tension be set at 4 1/2 ,when do I adjust the bobbin...


Hi! The bobbin tension rarely needs to be adjusted. First, make sure you're using the appropriate size needle and thread for your fabric (I'd probably use either a 'denim' needle or a universal size 14) and also that the upper thread and bobbin are threaded absolutely correctly. These can throw off the tension! Also, take the time to clean out the bobbin area. That can throw your stitch off also.

If the stitch on the bottom is loose, so that you see the top threads, then the top tension is too loose. If the top stitch is too loose and you see the bobbin threads on top, then the top tension is too tight.

It helps to thread the machine with different color thread on top and in the bobbin, and then stitch an inch or so on the same type of fabric as you're using in your quilt. Check the stitch. If you need to adjust the top tension, make sure the pressure foot is down! Adjust a little, stitch a few inches, and check again. Repeat until you don't see any (or very little) bobbin thread on the top or top thread on the bottom.

If you go through all these steps, and the bobbin thread is still loose (and you've tightened up the top tension), then there is a tiny little screw on the side of the bobbin case that you can use to adjust the bobbin tension. Turn the screw just a little bit (less than a quarter turn), stitch, check, etc. Once the bobbin tension is set, you shouldn't ever have to change it.

Let me know if this helps, ok?

Happy sewing!

Singer 301a...sews on top of fabric nicely...bottom is just loose loops of thread...it's like the bobbin is not sewing...I put 2 different colors in to see...top is perfect...on bottom of fabric I see the...


This is a tension adjustment problem. It's good to use two different colors of thread, like you did. From your description, the top thread (needle thread) tension needs to be tighter. As you tighten the tension of the top thread, you'll see that the top thread pulls the bobbin thread up into the fabric so it's no longer laying loose on the bottom of the fabric.

You'll need to have the pressure foot down when you tighten the tension. Tighten it a little, sew a practice seam, check to see what the stitch looks like. Tighten it a little more, sew, check, etc etc--until both top and bottom look the same--you shouldn't see much (if any) of the bobbin thread color on top of the fabric or the top thread color on the underside.

Let me know how this works for you, ok?

Husqvarna Vicking - The bobbin thread is knotting


Check that it is threaded correctly (both top and bottom) making sure that the upper thread is in the takeup lever. Watch the needle as you slowly turn the handwheel counter clockwise (toward you) and the needle point touches the fabric (make sure presser foot is down). Is the thread still relatively taunt? If it is loose, the upper thread tension unit does not have enough tension. Check the areas where the thread goes and make sure you remove any loose threads or fluff which could be inhibiting the tension discs from closing over the thread. If the tension unit still is not tightening enough, the tension unit may need to be replaced or the circuit board replaced. If everything is ok in the upper thread area, now look at the bobbin area. With no fabric, watch as the needle enters the bobbin area. Does it go down and the upper thread catch the bobbin thread and pulls it to the surface? Check for anything preventing the bobbin thread from being pulled up to the surface through the needle plate. If you have still not been able to resolve the problem suggest you take it to an authorized husqvarna viking dealer for service. You can locate a dealer near you by visiting the husqvarna viking website and clicking on the Dealer link on the left-hand side of the page - http://www.husqvarnaviking.com

Husqvarna Sapphire - thread cutter not working


Does the metal arm come out to grab the threads to cut it? Is there a blade in the metal arm that cuts the tread? I think a standard utility knife cutter blade is the same size (just like the one that cuts the bobbin thread when you put in a new bobbin). What happens when you activate the cutter is the arm comes out, grabs the threads, brings them to the blade which cuts the threads, the velcro by the cutter holds the bobbin thread in place for the next stitch. Otherwise the thread may end up on top and the top thread would not be able to pick it up for the next stitch.

Good luck.
