I'm betting that you put your bobbin in the bobbincase backwards. Hold the bobbincase between your left thumb and forefinger looking inside it. Pull the thread, the bobbin should turn clockwise, if it doesn't flip it over. And also your upper tension could be off and/or your needle isn't in right. Good Luck.

Singer touch sew 645


Singer website has a plethora of manuals to download, http://www.singerco.com/accessories/instruction-manuals is the link, your manual is there for $15. If the bobbin thread is knotting up in the bobbin then I'd say you need to rewind a fresh bobbin and make sure it is smooth with even tension as it goes onto the bobbin. If your bobbin thread looks a bit chunky and uneven, then you won't get good results from it. Also, check that you are putting the bobbin into the bobbin case the right way, the thread needs to come off the bobbin and make a reverse direction into the tension spring (assuming yours is a removeable bobbin case, not top loading)

1957 Montgomery Ward Automatic Zig Zag machine...Tension is completely out of sink. Top thread cannot feed through the tension track properly and breaks when I try to sew. How can I readjust the setting. ...


Bobbin with right diameter with or without holes. The bobbin has to sit below the top of the bobbin case when it is inserted. Make sure it rotates counter clockwise when installed. If there is a peg in the center of the bobbin case then make sure the bobbin hole is big enough to rotate easily.

1. Top tension approximately four. Get a feel for this pull on your finger.
2. Now-Bobbin case has a small screw adjustment; on left probably. Adjust this to be set equally with the top tension set at four. To do this:
a. Feed thread through the spring area while the bobbin is installed.
b. Adjust pressure of screw until it is equal to the top tension set at four.
The machine can now be operated.
If the thread knot is under the fabric then tighten the top thread. Do the opposite adjustment if the knot is above the fabric. It should be in the center.

I have a Brother Disney SE-2700 and the bottom threads knott up causing me to not be able to sew.Please help.


It sounds like it has not been correctly threaded or the tension is too tight. Check the tension discs for bits of thread that may have broken off and be causing a blockage.
Re-thread the top threads making sure the pressure foot is up before passing the thread through the tension discs!
Then check the bobbin is running correctly by pulling on the tail of the thread. The bobbin should rotate clockwise. Put the bobbin case in and make sure it is seated correctly.

If all this fails try replacing the needle. A blunt needle can cause all sorts of weird problems

Hello Supernana.

Check to see if you have your bobbin in upside down. If your machine requires it to unspool from one side having it spool from the other side (counter clockwise vs clockwise) can cause you problems like this. Your manual should tell the correct direction. My machine (Brother) for instance requires that the thread to pull counter clockwise direction.

Needles keep breaking & bobbing wont feed thru


First try taking your bobbin case right out of the machine (not sure if this model has a top loading or front loading bobbin, but your manual will help you here) and floss out the tension slot with a piece of strong thread. Don't use waxed dental floss, but non-waxed would work okay. (The bobbin case is the piece that the bobbin sits in.) Look around while you have the machine open and remove any fluff and thread you can see - TURN MACHINE OFF BEFORE DOING THIS! Replace bobbin case. Replace bobbin and make sure it "clicks" into the tension slot.

Then unthread the top of the machine, clean the tension disks by passing a folded dollar bill (or any paper money, depends on what country you are in) through the disks in the direction you thread the machine. Do this several times. Re-thread making sure you follow the correct thread path.

Make sure the needle plate is on firmly.

If after all that it still won't work, I'm sorry to say that it sounds like you have a misaligned needle bar. This commonly happens after you have a major thread snaffoo and needle breakage. The needle gets caught in the thread knot, pulls to the side and breaks but if it gets seriously caught it can pull the needle bar out of place. You cannot put the needle bar back in place yourself - it's a job for the workshop. Don't sew on your machine until it is fixed. The noise you are hearing is likely to be the needle striking against the needle plate or even the bobbin. Your timing will probably need re-setting too and this needs to be done by a qualified technician.

If you really need to sew before you can get your machine into the workshop, and if you can move the needle position on your machine by pressing a "sideways" button of some sort, you could try to get the needle in the centre yourself using this feature. This will not help if it is the timing that is the major problem.

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!

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.
