When i sew, the lower thread is in huge loops underneath and gets stuck in the machine underneath where the bobbin thread is. Please help me, I was on a roll making dresses for my baby girl who is due in June. I just got the machine a week ago. I have a singer Quantum 7360... The top thread keeps getting stuck in the machinery below the foot... I don't know what to do!
If you are seeing the needle thread in loops and birdnests then its the needle thread you need to check. The main reason is it is not threaded through the takeup spring(the one that moves) This action is critical as it is how the thread is pulled up tight. Also make sure the needle thread is between the discs and that it has sufficient tension that you do not see it on the bottom of the material. Try this: Use two different color threads for needle and bobbin. If you see the needle color on the bottom then the needle thread is not tight enough (or in 5% of the cases the bobbin is too tight or hung up). Let me know how it does. Jay
You may have your bobbin in backwards. Look to see which side the thread is coming from (clockwise or counterclockwise) and switch it. You may also have the wrong kind of bobbin. My machine (different brand) takes specific bobbins--who'd of thunk it!!! No problem when I switched to what the manufacturer recommended.

It could be the top thread is the problem. Might try removing all the thread. Consult the owner's manual for threading instructions. RAISE the presser foot BEFORE threading the upper thread so the thread will seat properly in the tension disk. Re-thread from the beginning carefully following the instructions--do not miss any spots or thread guides.
If top thread is still creating a mess of loops under the fabric, try tightening the upper tension. The tension is ideal when both upper and bobbin threads meet in the middle of the fabric.
Try these suggestions
1. Change the needle--use a needle that's for the fabric being sewed
2. Rethread the machine--top --make sure to use every thread guide
3. try a different bobbin--make sure bobbin is inserted correctly into the bobbin case, & make sure the bobbin is turned the correct way in the bobbin case
4. make sure the thread has not come off the thread take up lever
5. Clean under the needle plate & in the bobbin area for lint or threads
I know this sounds wrong, but I am very sure you are not threading it correctly. If the sewing is loopy on the underneath, it is not properly threaded on the top of the machine or not properly caught into the tension discs at the front/on the top. If the stitching is loopy on the totop, then the problem is underneath in the bobbin area. Sort of back the front-upside down.If you are sure you have threaded it correctly, then-1) Put the foot down to sew 2) turn the balance wheel to place the needle into the fabric 3) hold the threads to the back or side 4) start sewing. Because you are holding the threads, this stops them from being able to get caught up underneath. It will still happen if the machine is incorrectly threaded. If all this fails, what area do you live in??? Good luck, sewing is wonderful :)
Grab some scrap fabric of the same type you'll be sewing. Tighten your top tension and test sew until you see until you see the top thread of a seam go like a straight line and the bobbin thread loops on top of the seam. Then back off of the top tension until those loops disappear.
If you never see it the top thread go like a straight line... your top tension needs to be cleaned... and make sure you have the pressure foot UP when you thread the upper thread.
Check your top tension dial setting is on 5, as this sounds like the thread is not in tension fully so is looping up around the rotary hook and not being held back by the tension device. Is the pressure foot lowered (this turns the tension on) fully and is the thread through the tension discs correctly. Lower the pressure foot and pull the top thread from below the tension dial, it should feel firm to pull, if it comes out easy, its not undertension, device could be faulty and machine will need to be serviced.
Also, check that the bobbin case is fully inserted into the rotary hook in the correct position, bobbin is in and rotating the right way and thread is into the tension spring fully.
If you have the manual pull it out, and carefully check the threading up instructions and follow on your machine - it is probably one of these things causing the jamming.
Hi. So is this a horizontal hook? Where is the thread getting caught beneath the needle? Maybe on the hook? Check your upper threading to make sure the thread passes through the thread take-up lever. If thread is not through the lever, it wont get pulled up , which can lead to multiple thread loops getting caught on the hook, not pulling off after the rotation.
Try rethreading the top of the machine making sure you get it thru the tension wheel correctly.. General rule of thumb.
If it loops on the bottom, the problem in on the top.. Loops on the top, problem is with the bobbin.
Okay. I had this problem too. try taking the bobbin casing out. I had a bit of thread lintg caught in a remote area of the under-plate area. Blow it out with canned air and oil your machine. That should help. It fixed mine.
