The thread keeps coming out of the needle on top when I start sewing. Any help would be appreciated. I tried putting the needle in again, I tried taking the bobbin area apart and putting it back together and it still keeps doing it. Help please

hi Virginia.
you have not said what make you have.
but this is all i could find out.
Make sure your bobbin is threaded properly along with the top thread. It would help to know which machine you have. Mine has only one way to put the bobbin in so it will work okay, but I have had the thread miss the take up lever and it acted the same way (top thread). Keep trying.
Is it bunching as you first start sewing a seam? Try hold the bobbin thread and the top thread lightly when you first start your seam.
If you look at how the stitch is made, you'll see that the bobbin and top thread are interconnected, without a bobbin thread, you don't have a stitch. Check out the link below to see how a machine makes the stitch. It's pretty cool.
Are you bringing the bobbin thread to the surface before trying to sew? To do this, manually turn the wheel on the end of the machine so that the needle drops down into the bobbin race, while holding onto the tail of top thread. Bring the needle back up so that it's as high as it will go. Now pull on the tail of the top thread and it should bring up a loop of the bobbin thread. Pull up the loop so that the tail of the bobbin thread is up. As Marion said, you need to hold onto these tails when you start your seam, or the bobbin thread will get pulled down into the bobbin again and cause the snarling that you are having.

Here is a link that might be useful: Sewing machine stitch

When I have the thread bunching underneath, it is usually the upper tension that needs tweaking. Also, be sure that your needle is the right size and nice and sharp. A dull needle can really gum up the works.
When mine has done that it usually has lint under the bobbin case. Have you cleaned under and around the bobbin?
Make sure your bobbin is feeding off in the right direction.
I have just recently learned this. When you are threading your machine, make sure the needle and the presser foot are both in the up position. I am betting that would fix your problem.
I use to have this problem often. [sorry for the simplicity of this answer but it works for me] the needle goes up and down, when it starts it downward motion stop. this should be the position of the needle when you start to sew. hope this helps
or this link might help you out some more.

Thread keeps bunching up under needle plate Google Search

here are some suggestions
change the needle--make sure it's turned the right way when inserting
the new needle into the needle bar holder
check for burrs on the needle plate and in the bobbin area
try a different thread, some thread is just not very good

is the bobbin threaded correctly ?
is the bobbin warped?
try rethreading the machine top & bobbin
change the needle
Correct needle insertion is mandatory for proper use of your sewing machine.
Raise the needle bar to the highest point, then loosen the needle clamp screw to remove the old needle.
Place the new needle in the needle clamp with the flat side of the needle facing the back, (round needle, the groove in the needle should face away from the shaft).
Push the needle all the way up as far as it will go. Then tighten the needle clamp screw.
check to make sure every thread guide is used

first let's deal with the needle becoming unthreaded, Keeping the needle threaded is easy, always keep thread tails of 3 to 6 inches on the top thread & bobbin at all times, & make sure the thread tail are pulled behind the needle before you start to sew,, this will ensure that the thread will not come out of the needle when you start to sew.

you mention the fabric is thin,, do you have a needle that's right for the fabric your sewing?
thin fabric needs a different needle than blue jeans fabric, check your top tension & see what the setting is on, usually 3 to 5 is good.

when the needle & thread are right for the fabric then the sewing is good.

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

also it's a possibility that the machine could be out of time & would need to be serviced by a sewing machine repair shop-as they have the tools for the job

always keep 3 to 6 inch thread tails for the top & bobbin thread & make sure the thread is pulled behind the needle to the back of the machine & that will keep the thread from coming out of the needle

before starting to sew
1.make sure the top thread & bobbin thread have a thread tail of 3 to 6 inches
2.make sure the thread tails are pulled behind the needle toward the back of the machine

then put the fabric under the presser foot to sew

when your finished with the seam, after the thread is cut from the fabric,, leave the thread tail the same as above before starting to sew again

when starting to sew
1.make sure to have a thread tail of 3 to 6 inches on top thread & bobbin
this will keep the thread from pulling out of the needle when starting
2. make sure the thread tail is pulled behind the needle area before starting to sew

rethread the machine
try a top thread tension of 3 or 4
change the needle
always keep a thread tail of 3-5 inches on top & bobbin thread & keep the thread pulled back behind needle before starting to sew
always keep the bobbin area clean of lint & loose thread
& check under the needle plate for lint also
you might consider having the machine serviced, since you said it sounds like a tractor
some needle & thread are not compatable-try this

Cut 6-8 inch piece of thread of the spool you are going to use for your project
Take the needle you are going to use for the project
& insert the thread thru the eye of the needle
& lift one end of the thread to a 45 degree angle
& if the needle is the right size for the thread it will slide down the thread
But if the needle hangs on the thread you need one size larger needle for the thread

Try putting the bobbin in the other way, you may have it backwards, also you have to pull the threads out at least 6-inches from the needle before you start sewing or the thread uptake lever can pull the thread out of the needle.

Try a new needle, making sure it is put in properly. A bent needle can break thread. Make sure top tension is set properly.
