Why does top thread keep breaking?


Sounds like your tensions, both upper and lower are out of whack. Easily fixed if so...google a vidyfor your make/model machine on adjusting both upper and lower tensions.

When sewing a straight stich The bottom thread is loose.


Your upper and lower thread tensions are out of balance. The upper thread tension is too high or your lower thread tension is too low. Make sure your bobbin thread is correctly routed under the tension spring. There is a small screw on the bobbin case that always you to adjust tension.

Why is the bobbin thread bunching up?


if your saying that your bobbin thread is balling up under the platen plate , this is a sure sign that your top thread tension is not correct and there isn't enough tension to pull the bobbin thread up from below

How do to adjust the bobbin tension? Do I need to remove the throat plate and loosen the screws that hold the bobbin mechanism in place so I can get to the tension screw?


the tension screw for the bobbin thread is on the side of the bobbin carrier
that bit that you put the full bobbin in to clip it back onto the machine
t there is a small spring plate that you pull the bobbin thread under when you put the bobbin back in the carrier and you pull the thread down a slot and under that spring plate
the tension is adjusted by that small screw that holds that plate on
only very small adjustments make a lot of difference to the tension
don't touch any other screws or you will alter the needle /hook timing and that will put you a pickle

The needle thread keeps breaking, I'm using good quality thread and have tried re threading and changing the needle but it still keeps breaking, any advice would be most welcome.


1. Set the tension on the bobbin.
2. When you thread the upper thread do it with the pressure foot up.
While you are threading give slight tugs to check for snags. If there are snugs you must fix them.
3. Put the pressure foot down and adjust the tension to four. Give a tug. It should have tension but still allow the thread to flow.
(Look at your thread and look for fuzz on the sides. This indicates a bad quality thread. A good choice is embroidery.)
4. Make sure the needle has been installed going the right direction. Usually flat to the front or to the right side.
5. Turn the hand wheel while you hold the needle thread to the front.
The bobbin thread should come above the throat plate in about one turn.
NOW YOU SHOULD BE ABLE TO SEW.
LOOK AT INFORMATION ABOUT BOBBIN TENSION.

How to adjust the bobbin tension.


According to the manual, you should not need to adjust the bobbin tension (and I located other sites which stated the bobbin tension cannot be adjusted on this machine). Apparently, all the tension adjustment is accomplished through the upper thread::
"EN Thread Tension Upper thread tension Basic thread tension setting: "4". (1) To increase the tension, turn the dial to the next number up. To reduce the tension, turn the dial to the next number down. A. Normal thread tension for straight stitch sewing. B. Thread tension too loose for straight stitch sewing. Turn dial to higher number. C. Thread tension too tight for straight stitch sewing. Turn dial to lower number. D. Normal thread tension for zig zag and decorative sewing. Correct thread tension is when a small amount of the upper thread appears on the bottom side of fabric. Lower thread tension The bobbin tension has been set correctly at the factory, so you do not need to adjust it. Please note: - Proper tension setting is important for strong seams. - There is no single tension setting appropriate for all stitch functions, thread or fabric. - A balanced tension (identical stitches both top and bottom) is usually only desirable for straight stitch construction sewing. - 90% of all sewing will be between "3" and "5". - For zig zag and decorative sewing stitch functions, thread tension should generally be less than for straight stitch sewing. - For all decorative sewing you will always obtain a nicer stitch and less fabric puckering when the upper thread appears on the bottom side of your fabric. 1 A B C 22 D"

Doing further research, I found this statement on a machine review site:
"After reading reviews online from where I've bought my drop-in bobbin machines, I think many of the negative reviews are due to the bobbin thread coming up without laying across the bobbin. It can cause the stitches to look very sloppy and no amount of tension adjusting can fix the stitches."

There are several machine review sites wherein 4423 owners stated their disappointment in the 4423's performance. Some said the machine failed almost immediately and others said the machines developed problems when sewing heavy fabric.

My Singer XL 6000 upper thread is too tight and keeps breaking, when the presser foot is up the upper thread is loose, but when the presser foot is lowered the threah gets too tight, what I notice is that...


You need to loosen the tension on the machine. There is a dial that has numbers on it. The higher the dial is set, the tighter the tension is. Turn the dial to the left one number. Then try it. Do it over and over. Do not turn the dial all the way down or you will mess up your machine. Do it slowly, one number at a time and try the machine between dials.

I have a bernette 134 and the tread keeps breaking , the lower loop thread , no matter how I set the tension , upper or lower this thread keeps breaking , HELP


Serger thread breaks

1. Is the serger threaded correctly?

2. Is the needles inserted correctly?

3. Is one of the needles bent or damaged?

4. Is the tension adjusted too tightly?

5. Is the tension adjusted to accommodate thickness of thread being used?

6. Are you using inferior quality thread?

7. Is the thread feeding of the cone/spool freely?

8. Is the needle size correct for the type of fabric being used?

9. Are the needles being used the correct one for the serger?

10.check in the needle plate area to see if there is a burr

11. Check the looper to see if there is a burr or if it looks damaged


If all of the above suggestions don't help then the serger needs to be checked to see if there is something wrong with the loopers and also see if there is a problem with the tension.
