Bobbin Case Comes Loose When Sewing

If your Singer model 600e's bobbin case is stuck, try the following steps to remove it:

1. Turn off the sewing machine and unplug it from the power source.
2. Raise the presser foot and the needle to the highest position.
3. Open the bobbin cover and remove the bobbin from the bobbin case.
4. Locate the lever or button that releases the bobbin case from the hook race. Depending on the model of your Singer sewing machine, this may be a lever, a button, or a latch.
5. Use your finger or a small screwdriver to press or move the lever, button, or latch to release the bobbin case from the hook race.
6. Gently pull the bobbin case out of the machine.

If the bobbin case is still stuck, do not force it. Instead, seek assistance from a trained sewing machine technician or contact Singer customer support for further advice.

If your bobbin and bobbin case are stuck on your 880 Bernina sewing machine, there could be several potential causes for this issue. Here are some possible solutions to unstick the bobbin and bobbin case:

1. Check for any debris or lint that may be blocking the bobbin and bobbin case. You can try using a small brush or toothpick to remove any debris or lint that may be blocking the movement of the bobbin and bobbin case.
2. Check the tension on the bobbin case. The tension on the bobbin case should be adjusted to match the type and weight of the thread you are using. If the tension is too tight, it may be preventing the bobbin and bobbin case from moving freely. You can try adjusting the tension on the bobbin case using the tension dial or screw on the case.
3. Check the position of the bobbin case. The bobbin case should be positioned correctly in the sewing machine to allow the bobbin and bobbin case to move freely. If the bobbin case is not properly positioned, it may be preventing the bobbin and bobbin case from moving. You can try repositioning the bobbin case in the sewing machine according to the instructions in the sewing machine manual.
4. Check the condition of the bobbin and bobbin case. If the bobbin and bobbin case are old or damaged, they may be stuck or difficult to move. You can try replacing the bobbin and bobbin case with new ones to see if this fixes the problem.

If none of these solutions work, it may be necessary to disassemble the sewing machine and clean or repair the internal parts that are preventing the bobbin and bobbin case from moving freely. This is a complex task that should only be performed by a qualified sewing machine repair technician.

I don't know your model but my Janome 6500 has a bobbin case held in by magnet on the underside and it will dislodge and move if there is a jam up. This then prevents it from forming stitches correctly. You need to lift out the bobbin case and put it back into position. With mine, when it has moved, the needle then strikes part of the case when it comes down. This often results in a burr in the plastic which then causes the thread to catch again even when the case is back in correct position.
There should be two marks, one on the case and one on the outside to align it to.

this is my bobbin case, and the cut away part on lower part of the image is the bit that goes into the machine away from you.

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.

check with these 2 websites for the part ,,

it's possible the bobbin case could be a problem, I have 2 sewing machine & if one of them had a broken bobbin case I would replace it

have you tried a new needle

also check the thread take up lever, if the thread comes off of it, that can jam up the machine as well, I've had that happen before

also keep under the needle plate area clean of lint or loose threads & also the bobbin area

First 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. The bobbin tension adjustment is the small screw in the plate on the bobbin case that the thread passes under as it comes off the bobbin and goes out. This might not be exactly the same as yours but should give you an idea of the position.

if you have a snap in sewing table remove it first
at the bottom in front of the needle plate area is a bobbin case door
when you open it there is the bobbin case & also should be the feed dogs
always keep the bobbin area clean of lint or loose threads
take note of how the bobbin case is inserted in the bobbin area,, see where the thread tail is at on the bobbin case
then make sure the bobbin is wound correctly or it can cause sewing problems
reinsert the bobbin into the bobbin case the same way it's removed

I also have a necchi sewing machine, the base of your is like the base of mine, if you need a picture of inserting the bobbin,, send me a comment with your email address & I will send you a picture of the threading the bobbin case & inserting it

According to the manual, this is a drop-in bobbin.

If the bobbin case came loose, the needle would probably hit it and brake.

Take the bobbin out.

Turn of the power and remove the needle plate (under the presser foot).

Raise the needle to it's highest position and lift out and reset the bobbin case into the shuttle. This should be in the maintenance section of the manual. The bobbin case should fit snug.

Make sure the thread is feeding from the bobbin, counter-clockwise and through the guides on the bobbin case.

For a rotary bobbin with a metal bobbin case.

Remove the bobbin case. Make sure the thread is feeding clock-wise and through the guide on the side of the bobbin case.

Raise the needle to it's highest position - this puts the hook at the lower left. Left the tab on the back of the bobbin case and slip the bobbin case back into the shuttle with the "arm" straight up. You may have to move the bobbin case a bit to the left or right for it to snap into place.

If the problem persits, take the machine back to the dealer - there should not be a charge for fixing this as it is brand new - keep your receipt and warranty information at hand.

Viking bobbin case tension adjustment:
When the bobbin runs out, sometimes it bends the bobbin case tension spring. Then tension is too light. Take the bobbin case out of the machine. Tie the loose bobbin thread to the Designer 1 needle plate. Insert the bobbin in the bobbin case. Here’s the tricky part set the bobbin case on the table as if it’s in the machine (Bobbin is visible and sitting horizontal to table top) threaded as if sewing and loose end tied to needle plate (that is removed from the machine). Lift the bobbin case off the table rotate it so that the flat side of the bobbin are vertical to the table and no longer horizontal. Have the bobbin case oriented so that the thread coming out of the bobbin case sprint (slot area where it is put for sewing) is at the top. Lift it high enough that the needle plate is lifted from the table. It should not release thread unless you shake it gently and then a very small amount of thread. The needle plate is the exact weight resistance your bobbin case should have on the thread.
