The tension on my machine is off.I don't know which thread to adjust.bobbin or top thread. on fabric top stitch seems ok,bottom stitch bunches up and is loose.How do I readjust the tensions?


If the thread problem appears under the fabric, it is a top thread issue.

If the thread problem appears on the top of the fabric, the bobbin thread is the issue.

Perhaps the upper thread is not seated completely in the tension disk. Remove the upper thread from the machine, ALWAYS RAISE the presser foot, then rethread from the beginning. Make sure the thread path is correct. Test your stitch.

If the thread is still looping under the fabric, the upper tension is too loose. Set the upper tension to the midway point. Test and adjust the tension until it is where you want it. Preferred tension is when both threads meet in the middle of the fabric.

What am I doing wrong when the stitching on top of the material is ok and straight and the backside is knotting?


wrong bobbin tension , but amazingly its actually easier to adjust the top threads tension to compensate for it , use your tension knob to slowly adjust , try an inch , slowly adjust try an inch , and so on to get a top and bottom thread tension to match , this will need to be adjusted for each major change in fabric (aka , knits to woven )

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.

Bottom thread seems too tight!!! Help!!!


If the bottom thread is tight there should also be loops on top and this means that the upper tension is too tight.
Get out your manual (http://www.singerco.com/uploads/download/1198_8763-efs.pdf) and turn to page 24. Under "ADJUSTING TOP THREAD TENSION" it tells you that if you're having thread tension issues, change the tension control dial on the top of your machine from auto. It also shows you a diagram with your problem illustrated on the right side of the page. The bobbin tension is set at the factory, so all tension problems can be solved with top tension adjustment. Set it manually and if it loops on top, loosen the tension a little. Test again. Repeat until loops are gone.
Using different colours on top and bobbin and a contrasting fabric (e.g. black top, white bottom, light blue fabric) means you can easily see what's happening. A perfect stitch is when you see exactly the same stitch pattern on both sides of the fabric. On top, the bobbin thread colour appears between stitches as a tiny dot and on the bottom, you see the top thread dot between stitches.
If it's impossible to get the tension right, take it to a technician, because it's a sign that the hook timing needs attention.

I have a singer 7258 that I can not get the tension to loosen up on. The top stitch is straight across and adjusting dial doesn't help.


Hello

Adjust the tension

Load your sewing machine with one color on top, threaded through the needle. Load the second color thread into the bobbin and thread.


Fold the scrap fabric in half, and sew a straight stitch at least 2 inches long. Look closely at the seam. If you see loops of the bottom color thread on top of the fabric, proceed to Step 3. If you see loops of the top color thread on the bottom of the fabric, proceed to step 4.


Loosen the top tension. Since the top tension is so tight, it is pulling the bottom thread up through the fabric. Loosen the top tension by turning the numbered knob on the front of the sewing machine counterclockwise by one number.


Tighten the top tension. Since the top tension is too loose, the bottom thread is pulling the top thread down through the fabric. Tighten the top tension by turning the numbered knob on the front of the sewing machine clockwise by one number.


Sew a straight stitch 3 inches in length. Check the stitching. It is perfect if the threads meet in the middle, and you can only see the top thread on top and the bottom thread on bottom. If it still needs adjusting, go back to step 2 to repeat the needed steps.


Using two different colored threads makes it easier for you to see which thread is being pulled.

Always use proper precautions when working with electrical machines.

I have a singer 288. I think this may be a tension adjustment problem. The top or visible stitch is fine, however the bottom, when I flip the single piece of fabric over, is large loops. No matter how I...


no tension on the top thread causes this. either thread is not into top tension discs or tension device is broken, dirty or faulty. always thread with pressure foot up as when lowered it engages the tension and closes up the discs. you could try cleaning the tension by flossing between open discs using selvage edge of clean piece of cotton waste fabric scrap. turn tension to zero first and raise pressure foot. then rethread up and set tension back to 5 and test sew again. if still no joy then I would suggest a service by tech as tension may be broken.

Sears Kenmore sewing machine model number 15358 tension issues


#14 needle is way big for cotton napkin scrap. a #10 is good for most lightweight fabric. #14 is for sewing denim or levis, like that.

the tension problems on almost all machines regardless of price usually fall on the upper tension. the lower bobbin tension is factory set and it's rare you should ever need to mess with it.

if you have a drop in bobbin (top loading), tighten the adjustment screw all the way and then back it off 1/4 turn. if your machine uses a shuttle bobbin, tighten the adjustment screw all the way and then back it off in 1/4-turn increments until you can hold it in the air like a yo-yo and cause to bobbin case to fall slightly dipping your hand.

A dull needle and stitch length will also mess up your stitch. The idea is to narrow the problem down to one thing and one thing only -- UPPER THREAD TENSION.

So, if you have the right size needle for the job, with the right thread, and if your stitch length selection is correct (usually between 2 and 3 or 8-to-10 stitches per inch, the problem should be with your upper thread tension.

An easy way to fix this then is to remember: Loops on top, upper tension drop. Loops below, upper tension grow. If you get loops on top of your work, lower (drop) your upper thread tension to a lower number. If you get loops on the bottom, raise the upper thread tension.

Different stitches on the same machine will require different upper thread tension settings. Don't be afraid of it. Just remember the pneumonic: loops on top, tension drop, loops below, tension grow -- referring to upper thread tension.

have fun :)
