Question about Sewing Machines

Top thread keeps breaking and I do not think it is a bobbin issue. Thread seems to be getting snagged up in one of the upper threading spots. It has been professionally serviced many times.

Remove the top thread from the machine.

Install a brand new needle and confirm that the needle is correct for the thread and fabric you are sewing.

ALWAYS RAISE the presser foot and rethread from the beginning. Set the top tension to the midway point. Verify the thread path is correct.

When the presser foot is raised, the thread should pull through with very little resistance. Once the presser foot is lowered, the tension is activated and the thread should not pull through.

It could be the thread is catching a notch or groove. I have a machine that the thread has worn a sharp groove in the finish. I covered it with tape. Fixed.

The upper thread keeps breaking whenever I sew even though it is always properly threaded and the needle is fine

check the age of the cotton
cotton is not a single thread but a series of fine threads bonded with a glue
old cotton glue breaks down and the thread separates easilty
next check that the needle is installed correctly with the grove ( thread groove away from the bobbin hook
check the needle and hook timing because if it is off a fraction , the hook will pierce the the thread causing it to break
next check that the eye is the correct size for the thread in use
a needle eye too small for the thread thickness will jam the thread ans not let slide through the eye properly

My brother innovis machine has a problem. Top thread frays and breaks, not not seem to be picking up bobbin thread properly. I have changed the needle tried a previous bobbin.

Be sure to install a brand new needle--check that the needle eye is the correct size for the thread you are using--a small needle eye will shred heavy thread. It may also help to remove the top thread from the machine, ALWAYS RAISE the presser foot and rethread from the beginning. Verify the thread path is correct. Try different thread--AVOID old or bargain bin thread. Check that the upper tension is not too tight.

If the top does not pick up the bobbin thread, the machine may be out of time.

Otherwise, there may be a burr or snag somewhere along the thread path that is catching and fraying the thread. Sometimes there is a snag in the bobbin area (possibly the needle plate or hook) that is rubbing the thread.

How do I stop my tread from popping on my Brother (17 stich) sewing machine?

Breaking thread? Presumably the top thread? AVOID old or bargain bin threads. The upper tension is too tight or the thread is not properly seated in the tension disk, the needle is defective or the needle, needle eye/scarf is not the best choice for the fabric/thread being used, there may be a snag in the bobbin area that is catching the thread. Make sure the thread is not catching on the spool's thread notch.

Kenmore mini ultra The top thread breaks off from needle after a few stitches. The bobbin seems to Be catching the top thread. Thank you. ??

If the top thread sews a few inches and then breaks, something is catching the top thread and holding it until it breaks. Usually, this will happen when using the old style thread cones with the slit in the edge to keep the thread from raveling off the spool. To prevent the thread from hanging up, turn the thread spool over so the slit is at the top instead of the bottom. Sometimes top thread breaks will happen if the thread becomes looped around the thread spool pin.

Remove the thread, ALWAYS RAISE the presser foot and then rethread the upper thread. Verify that the thread path is correct and that the thread has not looped around a guide.

If the thread is fraying at the needle eye, the needle/thread are not compatible. Also, the tension may be too high.

Check that the upper tension disk is clean--no gunk buildup or thread pieces stuck.

If the thread is actually breaking when it penetrates the needle plate hole, there may be a burr or nick somewhere below that is catching the upper thread. You can wrap your finger with a piece of fine fabric, like an old pair of hosier, fine knit fabric, etc. and running your finger around in the bobbin area, under the needle plate. If you get snags, then you have a burr or nick. If it is small, you can sometimes smooth it with a fine emery board. If it is a large burr, you may need to purchase a replacement part.

Thread keeps breaking.had it serviced reciently.thread and tention correcthelp

1. Replace needle
2. Get good thread. One without fuzz. Usually embroidery thread is better quality.
3. Adjust the bobbin carefully. I've enclosed a guide how to do this.
4. Thread the top while the pressure is up. While threading the machine give tugs to check for snags. If there are any snags you must fix them first.
5. Check the needle to ensure it is installed the right direction. Thread the needle.
6. Adjust the tension to four. Pull just a little bit to see if the tension is a little or way too much which won't allow the thread to flow at all.
Once the tensions have been set correctly and there are no snags the sewing machine should run smoothly.

How do I set a straight stitch? What is causing the top thread to break?

You do not say which machine you have. As for a straight stitch, make sure the needle is central and not in zig zag mode.
The thread can break for several reasons, such as. Incorrect tension.
:Wrong thread for the material.
: Thread in bobbin different from the top thread.
:Old thread.
: Not threaded correctly.
: Needle not inserted correctly, or incorrect needle.or the thread could be wound around the spool holder pin,
Try removing the spool and turn it around.
Hope this helps.

How do I fix a White sewing machine #445 that keeps breaking the upper thread

Check the thread spool to make certain the thread is not getting snagged on the edge of the spool (or the little slit where you pull out the thread from the spool); then check your tension paths and settings (I once found broken, tangled metallic thread in the needle 'uptake' loop that was snagging the thread and making it break).
Canned air is excellent for cleaning out older models as well as the new electronic machines.

Top thread keeps breaking, I've re-threaded to make sure it's right, wound and re-inserted a new bobbin, checked the needle to make sure it's not bent (as described in the manual) and put it back with flat...

Not sure if you noticed but if you thread a machine with the pressure foot down it will not thread correctly. There are two little things that sorta looks like symbols for the tension on most machines. (learned this when my viking 600e kept breaking thread and I put it in shop) If you thread the machine with the pressure foot down it closes the symbol things and the thread will break as you described. If you have completed that correctly check the spool of thread. You may have a burr on the thread spool that is catching the thread that too has happened to me.

Cannot machine quilt without the thread breaking and/or shredding. I've change needle, thread type and size and tension on my fabric.

If the thread is shredding and breaking, there is an incompatibility of your needle, thread, and fabric. Could be old, bargain bin, or poor quality thread--does the thread have little "hairs" of thread lint sticking out of it--that's probably not good quality. Look for fresh, good quality thread. Try a brand new needle--a sharp if you are sewing woven fabric. Make sure the thread is not too big for the needle eye. Sometimes, a top-stitch needle or embroidery needle will work well on FMQ. (A top-stitch needle has a longer scarf which helps protect the thread during the multiple times the needle penetrates the fabric before the thread forms a stitch. Shredding means the thread is getting worn out before it forms a stitch. A piece of thread penetrates the fabric 10-20 times before it forms a stitch.) Could also be a snag somewhere that is damaging the thread.

Sewing Needle Troubleshooting Guide

SCHMETZ Household Needle Chart

Most FMQ instructions say the upper and bobbin tension should be the same, however, I find my machine works a bit better when the bobbin thread is just a little tighter than the upper thread. Then the bobbin thread does not "pop" up on the top of my fabric quite as much. It's probably something you will just need to experiment with in getting used to your machine.

P.S.--when threading your machine, make sure the Presser Foot is ALWAYS RAISED so the top thread will seat properly in the tension disk. Failure to do this will cause thread barfs (usually referred to as thread nests or bird nests) under your fabric. Also, before beginning your FMQ, ALWAYS PULL the bobbin thread to the top of the fabric, then hold both thread tails gently in your left hand while you slowly take the first couple of stitches.
