Oh wow. That's definitely not good. Well you'll need to replace the bobbin case, and needle plate. Even the slightest burr can cause havoc. you could try smoothing down burrs with some fine sand paper but you'll need to replace the case eventually if you can't get this problem identified and fixed.

Next look for a build up or stray threads under and around the needle plate/bobbin area. Make absolutely certain you have the right needles for your machine.

Turned out I am an idiot and had my needle in backwards, leading to the tangling. No idea why the needle plate would not unscrew, but my superhero husband got it off!

Hi,

It sounds like something on the bobbin case may have been knocked out of adjustment. I would take the bobbin case to a repair shop to have it adjusted. First, be sure you've cleaned all bits of thread that may have gotten caught in the area. Blow it out with compressed air if you have it. Then, start with a new needle and be sure you are threading the top correctly. Try it again and if a good cleaning and proper threading doesn't do it, then take the bobbin case in for repair.

Hope this helps. If it does, I'd appreciate your vote. Thanks,

Handie Andie

Has the bobbin case dislodged and moved? there should be two red marks one on the bobbin case and one on the outer holder, are they lining up? Sometimes as these cases are held by a magnet, they will get dislodged and move slightly, especially in a jam up.
Take out the bobbin case and clean under it, then replace it matching up the red marks.

If the bobbin case has actaully been struck by the needle during a dislodgement, it may well pierce the bobbin case plastic, look for burring or marks on the outer flange area. If this has occured, the thread may catch on the burr as it comes over the bobbin and jam again.

You can buy a new bobbin case if yours is damaged or maybe just file the burring with an emery board (remove it from the machine first of course).

Lastly, check your needle hasn't been bent, burred, or put in backwards, any of these can prevent a stitch from forming.

If all the above fails, then it is possible that the timing has been knocked out and you will need to get it serviced by a technician.

The needle can't be turned backwards manually

The needle should only go up/down. Sewing forward or reverse involves the feed dogs grabbing and moving the fabric. On most sewing machines, you should never turn the hand wheel backwards. This can change the timing and damage the machine. Instead, try holding the Reverse lever or button then turn the hand wheel forward.

Since the sewing machine jammed with the needle bar at its lowest point, open the bobbin cover. If you see a loop of thread, try and slide that loop until it clears. If there are several loops around the bobbin/bobbin case, you might try carefully cutting the thread. If the fabric of your sewing project has been stuffed into the needle opening on the plate, try carefully clipping threads to loosen the jam.

If that doesn't work, then double-check that the bobbin winding mechanism isn't engaged. If the unit is still stuck, you might have damage to the various linkages/bearings between the hand wheel and needle bar. The problem may require taking the machine in for service.

I hope these ideas help. Please add a comment with the make and model of the sewing machine for further assistance.

(When you do get the needle bar to go up, you may want to change your needle. Also change the needle plate to the straight stitch plate if you are doing a straight stitch with a lightweight fabric.)

Fabric is pulled into the bobbin area

You have probably got a needle hole in your bobbin case....the black thing the bobbin sits down into. One common problem is when folks take off their stitch plate to untangle a jam up, the bobbin case is not held in the right position and the first stitch after the clean out jams the machine. Check you are position the bobbin case correctly and the bobbin case has not been punctured.

Husqvarna #1+ sewing machine, is breaking needles under throat plate

This could be bad timing, or the needle is not in properly.
Make sure that the needle is pushed up all the way, and in the correct position. If the needle is too low, it will break.
Also, keep the bobbin case door open to see where the needle is catching.

The needle keeps breaking in my Yamata FY 910

The bobbin case rests on the lip of the hook and is is held into place by the position bracket. The position bracket is located at about 5 o'clock and has a small square end with a buffer spring. It must be positioned to hold the bobbin case securely and also allow the thread to pass through freely. It may be out of adjustment but may not.

If the bobbin case has turned, it is very likely to have suffered damage as it is made of a soft carbon fiber material. It not polished off, these damaged areas can snag the thread and jam the machine and create tension problems. Some gouges, burrs and needle punctures can be carefully sanded but you may need a new bobbin case. Use a 1500 grit sandpaper to smooth off the rough edges.

Bobbin case case keeps jamming

I am having somewhat the same problem with the exception that my needle did not break. I've cleaned and oil, but the bobbin case and projection positioned spring is not communicating to allow sewing to continue. The thread keeps jamming and the bobbin raises up the plate. So, what else am I to do?
