SOURCE: Stitch is uneven, not straight, and tension off on top and bottom

on my industrial machine this was caused by the wrong size needle. the length was off just a fraction. just an idea, in case you bought generic needles or something.

SOURCE: Top thread stitches correctly but bottom thread loops.

Make sure your bobbin is not in the case upside down and turning the wrong way.
Sometime people thread the machine with the presser foot down and the upper thread does not go between the tension discs, so check that.

FYI---- Loops on the bottom-- problem is in the threading..
Loops on the top--- problem is with the bobbin.

SOURCE: Zigzag stitch pulling tight, looks wrong

Try adusting the bobbin thread instead of the top. Always make sure to insert the bobbin so the thread is pulling in a clock wise direction. Both threads top and bobbin should have about the same resitance when pulled.

SOURCE: My four-year-old XL3500 seems to have a tension

according to the diagram in the manual, the upper thread tension is set by the wheel/knob on top and just to the right of the thread take up lever and thread guide. If you don't have a manual, go to www.brother-usa.com they have a downloadable manual for your machine.

How do I fix my loose bottom tension?


Remove the thread from the machine. ALWAYS RAISE the presser foot and rethread the machine from the beginning. Verify the path is correct. The standard tension setting is the midway point although you will most likely need to tweak this for your particular machine.

If you are still having problems, you may need to readjust the bobbin tension.

Bottom thread is still loose even if i try to balance the tension, how do i balance the thread tension?


You bobbin tension CAN be adjusted. First, thread your machine with different colors in the top and bobbin, set your top tension at its default, and run a line of straight, and then a line of zigzag stitches, and compare the results at the top and bottom. You will be adjusting your bobbin to your top tension. If the top tension looks like a straight line instead of stitching and the zigzag looks like "chicken tracks" instead of a zigzag, but the bottom looks like a zigzag, your bobbin tension is too loose.

Remove the bobbin case, and locate the straight-slot screw. There are generally two; one is a Phillips and one is straight--you want the straight one. Leave the other alone.

The rule is "lefty-loosy, righty-tighty." If your stitching displays the above symptoms, it needs to be tightened, so turn 1/4 turn to the right--no more--then test again. You will need patience, but don't turn more than that. It is easy to do, but if you don't do it systematically, you can make things worse, and very slight adjustments can alter the stitching significantly.

Not stitch zigzag


Have you tried a needle change? It could be blunt or the wrong size. Have you cleaned under the needle plate as the ridges get full of lint there. A toothpick will clean them out.

Top thread bunches


try changing the needle--use a needle according to the fabric
being sewed
if thin fabric is being sewed try using a stablizer
rethread the machine top and bobbin--use every thread guide
make sure the bobbin is inserted correctly and turned correctly
in the bobbin case
also try adjusting the top thread tension just a little

My top stitch is okay, however the stitiching on the bottom is wiggly, more like a zigzag stitch then a striaght stitch. Why?


try changing the needle--flat side to the back of machine
try adjusting the tension one number up--if it doesn't help put the tension back where it is
check to make sure the bobbin is in correctly
also check to make sure the bobbin is wound correctly
it's also possible that the machine is out of time which means a sewing machine repair shop would have to refix the timing of the machine, because they have the tools for the job

I am trying to do a rolled hem using a singer ultralock 14sh654. Do I disengage the knife? The stitches are uneven and some are quite loose no matter how much I adjust the tension. I am positive I...


no, you need the blade in place and cutting to give an even cut fabric edge. Set up for a three thread using the right hand needle, take out the left hand needle. move blade over to the right so it is cutting wide. Most overlockers there is also a thread finger you need to change on the foot, or a little lever you flick to move this finger forward into the stitching area. Check this on your manual as each make is a bit different.
If you can source it, put wooly nylon thread into the upper looper (knot it onto existing thread and just chain it through, the knot should go through the looper eye fine). Now turn the tension on top looper down so it is looser and tighten up tension on bottom looper, so needle 5, top looper 2 and bottom looper about 7.

Now test serge, the fabric cut edge should be wider than the overlocking seam so the fabric rolls under inside the stitching. Adjust the two looper threads so that this is happening, you want the bottom looper thread to nest right up against the needle stitch and the top looper thread to wrap all the way around too.

Once you've got this happening, turn the stitch length down to 0.5, to close the stitching right up. On some fabrics you'll need to adjust the differential feed too if the fabric is "waving" a bit.

Uneven stitches or sometimes loose when serging could indicate that one of the tension devices is faulting, so if this machine is not new and its doing this, it could need a service. Can you get a regular smooth three or 4 thread seam out if it???

It is always good to just recheck the threading path, make sure the thread aerial is up and that a thread hasn't got caught back on the thread stand somewhere if you're getting something wonky happening, threads stream off overlocker cones through the machine so anything wrong in the thread path will throw off the stitching.

If it was sewing correctly BEFORE the needle break...why did the needle break in the first place?...and what fixes did you make?
If it sewed properly...what changed?

Cut your upper thread close to the spool...make sure the presser foot is raised and pull the cut off thread section through/out of the machine from the needle area (sewing direction...do not pull the thread backwards!)

Clean out the bobbin area...remove any traces of lint or pieces of thread...look for any broken off needle pieces... brush the bobbin area out....then add a drop of sewing machine oil (but only if your manual says to oil that area).

Remove the needle plate to expose the feed dogs...brush/clean out that area too and add a drop of sewing machine oil...then secure the needle plate back on.
Replace the needle...do it again...yup...some needles arrive bad from the factory. Make sure the needle is inserted and positioned properly. Then thread the machine WITH the presser foot in raised position. (The thread needs to get seated into the upper tensions.)
..with the.presser foot down...thread the new needle.
Oh...and use the correct needle for the thread. (a universal 80/12 is standard).
Thread can cause issues too. Try a different bobbin, or maybe a different spool of thread to see if that makes a difference.

Suddenly zig zag stitch not working?


Because it is almost a straight stitch but the needle continues to move in a zig zag fashion is reason to believe it is in a long stitch. By changing the number of stitches per inch there will be a very noticeable looking zig zag stitch.
