Bobbin thread one big snarly knot

The bobbin thread is just turning into a big knot. Machine has only been used a couple times, and previously worked OK. Totally rethreading top & bottom and a new needle didn't help. Stitch type/length and Thread tension is OK. What else can be causing it

Re: Bobbin thread one big snarly knot

Part of the mechanism to advance the fabric is defective. Have the feed teeth dropped?. Mine appear to have. I still have to work on my two machines with the same problem. It is exactly like asking a solicitor an answer as it was on the Jimmy Young programme. The questioner received the stock answer "See a solicitor". Jimmy Young called me a B. Gitt when a reprimanded solicitor actually made an attempt at answering one of my questions.

Re: Bobbin thread one big snarly knot

First ensure that your bobbin is threaded correctly. Most drop in style bobbins the thread will feed off in a clockwise motion. Also make sure to only move the hand wheel (on the right) toward you (counter clockwise). When you begin sewing ensure that you start with the needle in the fabric and when you end that your needle is in the highest position.

Check the bobbin tension and that the thread is tight around the bobbin. Make sure that the bobbin is in the right way around - the bobbin thread should double back on itself coming out of the bobbin holder.

There has to be a problem in your threading or your needle. You may have the needle inserted backwards, flat side has to face rear or the needle is bent. Totally unthread your machine and make sure that there are no tangles and that it feeding the right way. Watch how they show your for threading and winding the bobbin, plus threading the bobbin. Good luck, but I truly think it is in your threading.

Bobbin Thread is "birdnesting"

Get out the manual and refer to the maintenance section for cleaning the machine.

Especially the bobbin area. You want to make sure the area around the bobbin case is free of lint and thread.

Use a new bobbin and re-thread the machine, with the presser foot UP.

Install a new needle, again according to the directions in the manual. Installed incorrectly can lead to mis-stitching.

If the problem persits, the timing may need adjusting.

This should be done by the sewing machine tech for Kenmore. has a guide for this in the repair section, but you could end up with more problems.

Bobbin thread keeps breaking

Could well be that the bobbin tension is too tight, you should only just be able to pull the bottom thread through with slight resistence, if it is too tight slacken the screw on the bobbin case anti clockwise about a quarter of a turn at a time and test until you get it right,

Upper thread knots up with bobbin thread when sewing a stich

Thread test
Test your thread quality to start, thread your machine and LIFT the presser foot (this opens the tension disks). Pull your top thread straight back. If you feel no tension no mater how much thread you pull, your thread is good. If that your machine passes that test, then let me know, we can go to step 2. If not, try different spool of thread, same test until you get a smooth pull (tip: always check your thread this way when you thread your machine)
Step 2:
Pull on your threaded bobbin thread while it’s in the machine. Does it pull smooth and even? If so, go to step 3. If not, try a new bobbin (bobbins get bent or distorted if wound too tight).
Clean thoroughly in the hook and bobbin case area and oil 1-2 drop is all.
Thread knotting on the bobbin can be a lot of things but here's some guidance:
If the thread is loose on the bottom of the fabric, it's actually the top thread is too loose. Think of 2 little elves playing tug of war in your machine, one on toip and one underneath. If you have loops on bottom, the top needs to pull harder (tighten top tension)
Jamming bobbin case:
If it is damaged from turning out of place once, it could have rough spots on it that makes the thread hang on it, and keeps making it turn over and over. Use a finger nail board (fine sanding) and smoothall rough spots. Then reset the bobbin case taking care to put the notch in the bobbin case in alignment with the proper spot in the machine (basically 5 o’clock) when looking at the round area where the bobbin case goes.

Thread getting knotted

My machine does the same thing. Unplug the machine, and open the bobbin case. I would bet that you have "orphan" thread still sitting in the bobbin area that is bunching up the new thread.
Your bobbin area should be opened, cleaned and well oiled to ensure that no loose threads are sitting in there waiting to create "tension" with you and your machine.
I have found that when I have not cleaned out the bobbin area, there are loose threads, lint and fibers left behind from other projects that I have been working on.
Get a new can of compressed air, and blow out the lint, and left behind stuff, and see if that doesn't fix your problem. If it's been a while since you have taken it in for a "tune up", it should be done if you use your machine often. Happy Sewing!

Problems with Singer 2732

"Birdnesting" occurs when there is no tension on the needle thread to pull the bobbin thread. This is easily corrected by rethreading the machine, following the threading path carefully and making sure the thread is fully engaged in the tension mechanism.

Bobbin continues to pose problem - knotting thread underside of fabric,

In 99% of all problems with "bird's nesting" or "knotting" it is an issue of the thread coming out of the take up lever (at threading guide #3) (from the spool; through the first thread guide at #1 down to #2 and up to # 3) when the thread comes out of the take up lever, the machine can not regulate the thread and it floods the machien with thread and wraps itself around the bobbin case. OR! Your tension is too loose. Raise it. Your machine should preform perfect at tension #4 unless you are using speciality threads or fabrics.

ALWAYS be in the habit of threading your machine with presser foot up so that while threading between paths 1 and 2 you are certain to have the thread pass throught the tension disks.

This will happen on a $50.00 machine or a $5,000 machine. The thread needs to be regulated.

Thread knotting around bobbin case

hello, I had the exact same problem and could not find the solution until i took my machine to my sewing sensei and i solved my tedious problem. It was actually not a tension problem at all but a threading problem. Make sure you have threaded your bobbin correctly and that when you pull on the bobbin thread that the bobbin turns the right way. (mine must spin anti clockwise to work)  Make sure that when you pull up the bobbin thread using the needle that it is not over the feed dogs connective bar but under it. A big problem when the thread gets caught around the bobbin case wheel is that the thread is looped around the feed dogs once and that causes the thread to get caught around the bobbin wheel. In conclusion, thread the bobbin correctly and read over your instruction book before spending the money to get it fixe in s shop.

Thread tension?

I own this little gem of a machine. It definitely sews a perfect stitch. I'm assuming you own the green 3/4 size machine as denoted by your product number. The half size blue one pictured is incorrect.

Anyway, this machine sews a perfect stitch, due to the oscillating bobbin. Most sewing machines with rotary (drop in) bobbins don't have an easily accessible bobbin tension screw, which means your fabric is usually slightly puckered. Fiddling with only the upper tension helps very little. This frustrates me to no end for sewing long curtains, clothing side seams, etc. Wrong tension causes them to hang with puckers, making them look awful. With the Hello Kitty 3/4 size Janome, there is a screw on the bobbin case which allows you to adjust for every thread diameter perfectly. Always a perfect stitch, if you take the time to adjust this screw.

To adjust the bobbin for a perfect tension, load the bobbin into the bobbin case and thread it through the guide. Holding only the thread between two or three fingers, let the bobbin case dangle below. This will be slightly difficult, because the bobbin will want to fall out of the case. Don't worry, just don't move it around too much and it will stay in long enough for this test. If the metal bobbin case slowly drops lower, unwinding thread as it goes, the thread is too loose. Tighten the screw on the side of the bobbin case a little (about a quarter turn.)

If the bobbin case seems to be dangling firmly, give the thread a gentle tug, lifting up fairly quickly. If it doesn't release a couple of inches of thread, it's too tight, loosen the screw. You know the tension is perfect when a quick, light tug of the thread releases a couple of inches of thread.
