This is generally called bird nesting or thread nesting. It is frequently caused by the machine not being threaded properly, the thread not being seated completely in the tension disk, or the upper thread tension too loose. Remove the upper thread. When threading the upper thread, ALWAYS RAISE the presser foot. Check that the thread path is correct. Then set the upper tension to somewhere around midway between high & low numbers. Be sure to use a brand new needle to get the best sewing results.

It also helps to bring the bobbin thread to the top of the fabric before beginning to stitch. This works whether you are quilting or doing any other sewing.

I have just been given a singer melodie 40.When I start to sew, material is stopped by bobbin? Bobbin is breaking off bits of thread underneath?


Try a brand new needle. Make sure the thread is suitable to the needle and fabric you are using. AVOID old or bargain bin threads. Spend an extra dollar or two for good thread.
All About Needles

Check that there are no loose threads stuck in the upper thread path, ie the tension disk.

ALWAYS RAISE the presser foot when threading the upper thread. Verify that the thread path is correct. Mis-threading will invariably cause broken thread.

Clean out the bobbin area & feed dogs of any lint and loose threads. Check that the bobbin has been installed & threaded correctly and turning the right direction in the bobbin case.

Manually rotate the handwheel one turn until the upper thread grabs the the bobbin thread. Pull it the rest of the way to the top. When beginning to stitch, start slowly and gently hold both thread tails in your left hand until it has made a couple of stitches.

How and Why to Bring up the Bobbin Thread

If you have a manual, make sure you follow the maintenance tips. If the machine needs oiling, be sure to follow the instructions using only fresh good quality sewing machine oil. Most machines that have been given as gifts from a sewist's stash may not have been maintained regularly.

If it still does not stitch properly, take it for service. It could have a timing issue, ie the needle arrives at the bobbin at the wrong time to intercept the bobbin thread.

My minghui is sawing just top and bottom is just mess can u help me???


Thanks for the question.
If your machine is not sewing on the bottom or making stacks of thread called (bird nesting) there are several simple fixes for this and some not so simple.
First you need to make sure that you are threading the bobbin into the holder correctly, Insure that you pull the end of the thread through the little slit on the side of the bobbin and that the thread is somewhat snug but not hard to pull.
Once you have done this replace the bobbin in the bobbin holder and thread the feed thread over the top from the spool or thread. making sure that you run it through the auto tensioner.
Set the auto thread tension to +1 to start, go ahead and thread the main feed through the bobbin feed so that you have both strings on the sewing deck.
Now with a piece of used material, pull both bobbin feed and Main thread behind the machine, insert your test material, drop the material tension foot onto material and start to sew a 1 inch spot.
After about one inch check to see if your machine is still nesting thread, if it is you need to add more tention to the main thread by moving the auto tensioner to +2. Now test sew again a short distance and recheck. If you still have a issue move the tension up until the nesting of string stops.
If you reach the stop. than it\'s likely that the bobbin holder needs to be adjusted.
The bobbin holder has two small screws in it generally that allow a very small screwdriver to adjust the bi metal pensioner on the bobbin holder. This is the area where you slide the string through the little slot in the bobbin holder.
You can tighten those screws until the string is harder to pull out of the bobbin holder. You may have to repeat this step several times until you get the tensions just right.
but make sure that you reset the main Thread tension to 0 before you start adjusting the bobbin tension.
If after all this work fails you may have to replace the bobbin holder to correct this issue.
There is one other fix that you can try before replacing the bobbin holder and that is to purchase more expensive thread. The reason behind this is that the more expensive thread is thicker and causes more friction in the bobbin holder..
I hope that this has helped you, I know what it\'s like not to have a working sewing machine.
Best of luck and thanks for using Fixya.com

Embroidering in blue thread, and the white bobbin thread was coming through on the material. Adjusted the tension to -8, sprayed the bobbin casing and area lightly with WD40, changed the bobbin, changed...


The white bobbin thread was showing on the top of the material correct? Make sure bobbin thread is in the tension correctly, check the top thread spool and make sure thread is not caught around it, if you have a manual top tension make sure that is set correctly. Personally I would never use wd40 in a sewing machine, sewing machine specific oil is always better. You seem to be describing two different problems. The thread bunching is probably from the thread jump out of the take up lever.

The bottom stitching looks like a line and not stitches the top stitching is fine


whether its bias or straight does not matter to machine. loosen the bobbin tension and put more tension on take up spring by inserting a screwdriver in the slot of the top thread tensioner. turn to right.

How do you adjust the bobbin


Hello

Set the tension on the sewing machine for the weight of the material you want to sew. The tension setting shows in the stitch on the material. Use the chart on the machine that matches types of stitches with suggested material tensions. An example of this is, the stitch to sew jean material is different than the stitch to sew silk.

Take the bobbin and wind the thread around it. Make sure the bobbin is empty and don't fill it too full of thread. A bobbin filled too full won't stay tightly spun.

Thread the string evenly on the bobbin. Move the thread back and forth evenly and in layers that are level. Many Singer sewing machines have a bobbin winder on the top of the sewing machine, and the consistency of how it threads can save you frustration later.

Find the hole on the bobbin that is located near the inside spindle of the bobbin. Take the thread sitting on the sewing machines spool and insert the thread in the hole from inside the bobbin to the outside. Set the threaded bobbin on the spool designated for spinning on the top of the sewing machine for some Singers.

Turn the side drive wheel slowly until the threaded bobbin has a layer or two of thread on it. Push down on the drive peddle and fill the bobbin, but don't thread it to the very edge. If the bobbin is too full the thread will release erratically. Cut the thread from the spool.

Drop the bobbin into the bobbin case under the area where the needle sews the material. Close the case and turn by hand the side wheel drive until the bobbin threads into the sewing machine. You can tell when the bobbin is threaded by the tiny piece of thread that juts out of the bobbin case where the needle goes up and down.

Grab the thread with your fingers and pull it out approximately 4 inches. Your bobbin is now spun and threaded.

My quilt expression 4.0 requires rethreading a lot. It'll stitch along just find, and then "clunk! clunk!" and the thread underneath gets jumbled up (which I've been told is a problem not with the bobbin...


Sounds to me like a tiny bit of thread may be caught in the bobbin assembly. I have a couple of machines that will come to a screeching halt when this happens!!

What you'll need to do is take your bobbin assembly apart and brush out off the lint and thread you can find, then use a bright light and magnifying glass to look for any bits that might still be in there.

Good luck and I sure hope this fixes your problem! Let me know, ok?

Stop sewing! You need to adjust your tension. Your book will explain exactly how to do this. If you can't find your book, try setting the tensions to the same number. If your tension adjustments have a mark at a certain number, use that setting for most materials. If not, try setting it to about 3.

To test your settings, thread your bobbin with a different color, then do a test stitch. Check the top and bottom stitches for a spot of the other color thread showing through. If the bobbin thread shows in the top, raise the bobbin tension setting a bit and try it again.

Hope this FixesYa!

Loose stitches every 1


test it out on 2 pieces of material by rotating the wheele by hand. pay close attention to the 1" area. when you turn it by hand you can feel the area of question. is your bobbin spooled correctly. if all fails read the directions.
