Was sewing fine, then started jamming. Thread is getting caught and tangled below the feed dogs, needle bounces up and down, hand wheel won't turn. Tried re-inserting bobbin, same thing happened. Then took apart lower section, pulled out loose thread, which seems to have wrapped itself around the bobbin case. Brushed everything out and put it back together, it did the same thing again. Also tried re-threading upper thread, same results. Have Shark model # 9110.

Re: Thread getting caught underneath
You need to replace your shukle that holds the tread bobbing below.it is either slack or broken . if it is slack then you tighten the little screw that holds a cover that gives the thread tension .if its broken then replace it.once the thread is slack below it will cause your thread to bundle up.

The needle never moves forward/back on its own for most sewing machines. The needle bar goes up and down. The fabric moves due to the action of the feed dogs. First remove the fabric from under the presser foot. Check for tangled thread wrapped around the feed dogs or fabric/thread going down into the bobbin area in a tangle. Next check if the feed dogs are up. (When the feed dogs are down or covered (on some machines), the machine is in darning mode. The fabric will only move if you move it yourself.) With the fabric out of the way, rotate the hand wheel and check if the feed dogs are moving. Open up the bobbin compartment and clean out any lint, thread or other debris that may be tangling the mechanism. Take off the throat plate and check the feed dogs. A damaged throat plate can stop the feed dogs from moving properly. You may need to replace the throat plate.
For some machines, you may need to make sure that the unit is not in bobbin wind mode. This is usually obvious since the needle bar won't move either.
Check to be sure you have not inadvertently dropped the feed dogs on your machine. Dropped feed dogs are used for 'darning' or 'free motion quilting.' Below is info from Troubleshooting Manual:
Fabric does not feed through the machine The feed dogs are lowered. Use the feed dog position switch to raise the feed dogs. 81 The stitches are too close together. Lengthen the stitch length. 42 The wrong presser foot was used. Attach the correct presser foot. 179 The needle is bent or blunt. Replace the needle with a new one. 34 The thread is tangled. Use scissors, etc., to cut the tangled thread and remove it from the race, etc.
In my Brother CE-4000, it appears as though the feed dogs (which you can change to a higher position or a lower position) are allowing the bobbin case to spin all the way around and then the needle hits the bobbin case. When the feed dogs are in the lowest position, the bobbin case does not spin all the way around when the needle moves up and down (and therefore the needle does not get stuck in the bobbin case. I am wondering if this is a problem with the feed dogs/case?
clean under the needle plate where the feed dogs are for lint
also get a can of air & use it on the bobbin area
change the needle
rethread the machine top thread & bobbin
make sure the bobbin is not warped or damaged
check the top thread tension
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.
It should move a little so the thread has clearence. If the thread is bunching underneath, it usually means the thread's not in the take-up lever or top tension is too loose. If you're needle has hit the bobbin case and created needle marks, the thread can get caught... in which you'd need to replaced the bobbin case.
when the needle pulls the fabric into the feed dog you dont have enough fabric behund the neelde when you srart, and the fabric gets caught in the feed and the bobbin case underneath clean it out anf change the needle they often get bent after they get tangled in the thread and fabric
Hi Jeanette! You have a Singer Featherweight--the best sewing machine ever made! (Mine dates from 1950/51 and I wouldn't trade it for the world.) These beautiful, sturdy machines were designed to be easily repairable at home, but you'll need a copy of the Service Manual (get the Instruction manual too, if you don't have one.) Go to www.singer-featherweight.com and check out what they have available.
I had a similar problem (needle thread not catching the bobbin thread) and the problem was that I hadn't put the needle in correctly (flat side to the left). Also, I will occasionally get thread wrapped around the bobbin housing--sewing along just great and then everything comes to a screeching halt. I'm not sure why that happens, but I'm getting pretty good at taking the bobbin housing apart. The manual is pretty clear on how to do it. You can contact me direct at firstname.lastname@example.org for more information.
