    Cleaning the lint from bobbin case and adding a new needle fixed the problem. I will keep the rest of the info for possible future use. Thank you

SOURCE: Difficulty adjusting tension to avoid bobbin looping

it sounds like your bobbin tension is too tight. to adjust bobbin tension, remove bobbin case (remove needle plate first) and adjust bobbin tension screw on side of case until bobbin thread has a slight resistance as you pull it through the bobbin case.

this will be trial and error until you get best result. you should always try and match top and bottom threads. if the top thread is quite thick you may have continue to increase needle thread tension until balanced.

SOURCE: how do I know which tension to adjust?

Are you sure that a stitch is being created each time, or is it missing some....

On a scrap, sew a zigzag to ensure that at least the stitches are being formed, if not, or missing some, look to timing.

This solution is for tension problems...if you cannot form any sort of stitch, the issue is quite different, so please let me know if you need a different problem solved.....

It is quite long, but just work through each section in order.
The "knotting up" can reveal a lot. If you have loose threads on one side or the other, the tension on the opposite side will be the culprit.

QUICK SUMMARY FIRST:
Ensure sharp new needle,
Thread guides and Bobbin are Clean & Clear of lint
Set Top Tesion to 4 ....then....
Balance Bobbin to suit.

TOP THREAD TENSION:
If the looping threads are on the underside as you sew, it is the top tension. Top tension ought to be between 4 & 6 (this variation to allow for the different weights of fabric in your
projects).

IS YOUR NEEDLE SHARP ?
If you are using a needle that has seen quite a deal of work, or you suspect it may be blunt, change it for a new one !

TOP TENSION & GUIDES:
Make sure that when you thread the machine the presser foot is up so the thread goes between the discs and not to one side, top tension between 4 and 6, and that you have threaded through all the guides, including the last one, usually on the needle arm, just above the needle clamp.

It may be there is lint trapped between the discs, this will keep them slightly apart and reduce the actual tension, sometimes dramatically.

If tensions appear correct, and the thread is definitely in the channel between the discs, but still too loose and looping, try raising presser foot and remove your thread.

Now, with a 2" (50mm) wide strip piece of fabric 8 - 10" (20 - 25cm) moistened with methylated or denatured spirit, gently insert the fabric strip and clean between the discs with
a see saw / to and fro action.

In the worst cases, gentle use of a needle to pick & remove the jam may be necessary, but be very gentle and make sure the tension is set at Zero and the presser foot is raised, (to
disengage tension plates).... do not gouge or score the plates, they need a polished surface to work correctly.

BOBBIN TENSION:
Far less common, but if the loose threads are on the top, it is bobbin tension that is loose, it too may have lint in the spring and be giving a "false" tension.

I would not recommend fiddling with bobbin tension without good reason, it may end up with missing small screws and spring pieces, however, you can take the needle plate off to clean
the hook race area (where bobbin case sits)

...this is just good housekeeping, my wife does this every time she replaces the bobbin....

just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint. If there is a significant amount of lint, use a vacuum and small brush to get the worst.

Then wipe all this area with a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit, especially if there appears to be fine dirty deposits....oil and lint combine to conspire against you.

If it seems likely that you ......really ....do .....actually .....need .....to adjust the bobbin case, first check there is no lint trapped in the metal spring where the thread is tensioned.

TOP LOADER:
Drop-in Bobbin case will look similar to this image with the tension screw in the middle of the metalwork....

4c76dc1.jpg ...the other screw at one end is holding it all together, so beware....it is not a tragedy to undo the whole lot and clean it, but very gingerly and lay the bits out in sequence and orientation, or you risk tearing your hair out !

FRONT LOADER:
....this is a bobbin case from a front loading machine and works in a very similar fashion to the top loader with drop in bobbin, again, if you dismantle it, take care so you can put it all
back properly.
165ca5c.jpg FINISHING UP
GETTING THE BALANCE RIGHT:
When you are certain there's no trapped lint in top tension or bobbin, set the top tension to 4 and the bobbin tension to a point where you just begin to feel resistance.

Try using good quality thread of contrasting colours so you can more easily spot the changes.

Set your zigzag to one width less than maximum (eg. 5 of 6 ...or... 4 of 5 etc) and sew a sample for a few inches and check the result.... adjust the bobbin tension screw very little at
a time, perhaps 1/16 of a turn.

You may find you are playing with this balance for some little while and if you are putting the needleplate on and off each time begin to think it cannot be correct to do this.....BUT....it is,
and eventually, you do get a "feel" for the correct tension and then it happens quite quickly.....as a user you won't be doing it very often unless there is lint built up (or are there small hands at work around the house !?!?!)

OTHER ISSUES:
If you live near the ocean as we do, salt air can play havoc with metalwork inside and out, so to help minimise this, keep a few small packets of dessicant (silica gel) in your machine
case....no case ? then make some sort of cover !

Same applies in any damp or humid environment, keep your machine dry and dust free.

Budget for a proper full service every couple of years (more often if heavily used) and if you don't use your machine for a few years, be aware that old oil will dry out and combining with
dust and form a "clag" like glue (another reason for some sort of cover, even a teatowel !)

FINALLY, A WORD ON THREAD:
If it is worth spending the time, energy and money on making something that you would like to give lasting enjoyment......use quality thread, .......it may seem to cost a little more at the
time, but the results, ease of use and added longevity will be worth the extra, and as a bonus, your tension troubles may be fewer and further between, because there is a more consistant diameter with good thread, and less compensating to be done by your tension plates and less thread breaks !

SOURCE: top thread keeps breaking

This sounds like a backwards needle. Take out the needle and when you re-insert it back in, make sure that put the flat side to the back.

SOURCE: I can't adjust my tension correctly. The

Let me give you general instructions on adjusting machine tension. Make sure you thread the top with a different color thread than your bobbin so it's easy to see what's going on.

Thread your machine with the presser foot UP. The disks that control the tension (threadgoes through them) are tightened up if the foot is down. Change the machine tension with the presser foot DOWN.Because the disks won't be engaged (see above) if the foot is up, the diskswon't move. Start at the middle setting, 3. Go up to tighten, decrease toloosen. Each machine is different, even 2 different machines of the same model.The best thing to do is start at 3 and use a different color in the top andbobbin thread so you can easily see what changes to the tension do to yourstitches. Now use a straight stitch a sew 3 or so inches. Take a lookat the top and bottom of the fabric. You don't want to see any (or at least notmuch) of the other color showing from the other side. Loops on the bottom of the fabric means you need to tighten(increase) your top tension. If you're stitches on the bottom are causingpuckering, then you need to loosen you're top tension. For the most part, youreally don't want to touch your bobbin tension-leave that to a repairtechnician. The factory setting shouldn't be touched except by someone whoreally knows what they're doing. Keep sewing a few inches at a time until you have the resultsyou want. Now you're tension is where you need it!
Good luck!

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.

Thread tension


try changing the needle first--make sure the needle is the correct one for the fabric being sewed.
if you've adjusted the top tension & the bottom stitch still looks the same
it's possible that the top tension dial is needing to be checked to see if it's
working correctly

New Home ss2015 machine. I am having trouble with the thread tension. I have loops on the bottom. I have cleaned the bobbin case, changed the needle, re-threaded and moved the upper tension all the way up....


try adjusting the top tension to 3 & if it doesn't stop the looping, try 4 but I wouldn't go any higher than 5,, if changing the top tension doesn't help then I suggest taking the machine in to have it serviced. the bottom tension is more difficult to do,, it's also very possible that the top tension dial is messed up & needs replacing. only a sewing machine shop can tell for sure.

I have a Viking/Lisa Model. I am having trouble with my tension and I am not sure if it is the top or bottom. My bobbin thread is all of the sudden too loose.


I just bought a Viking Lisa, and also had to adjust the tension. Use the manual to make sure you've threaded the machine correctly and put the bobbin in correctly. (I wasn't getting the bobbin thread the way it needed to be.) Then gradually increase the tension on the dial inside the top cover, checking the bobbin stitches every two inches, ending up on about 4 1/2. If this doesn't take care of the problem completely, gradually increase the side tension dial, and between adjustments on both dials, you should end up where the stitches look good. Also make sure to use cotton thread; mine doesn't like polyester thread. :o)

If the loops are forming on the bottom it is the TOP thread tension you need to check. Make sure it isn't too loose. Also is the needle the right type and size for the fabric? Check the stitch out on plain cotton fabric if a tension adjustment doesn't fix it.

The TOP thread effects the UNDERSIDE of the stitch and the BOBBIN thread effects the TOPSIDE of the stitch :)

The bottom stitch is very loose. I've tried tightening and loosening the screw and the problem remains...HELP!


The bottom stitch is affected by the TOP thread tension :) First go back and make sure your bobbin tension is correct since you adjusted it. It should drop slightly when held suspended by danging it by the thread. If it reels out to the floor it is too loose. If it doesn't drop at all it is too tight.

Now that you have that adjusted look at your top tension. If it is loopy on the bottom side of the stitch the TOP tension is too loose. Increase the top tension.

Now take some scrap material and set machine to a wide zig zag, medium length stitch and sew a bit. Compare the top and the bottom sides of the stitch. They should look identical. Remember the TOP side effects the bottom and the BOTTOM tension effects the top side. Adjust accordingly until they look identical with no loose threads or loops and no puckering (puckering means it's too tight).

I am sewing a cotton piece of fabric for a dress and i do not know how to set the tension for cotton


The tension for cotton is set the same way tension is set for any fabric:

1. The thread should pull freely with a small resistance before/after it goes through the needle, on many machines that's half way on the tension adjustment.

2. The bobbin thread when dangled by the thread with the bobbin inside the case should drop down a bit when slightly flicking your wrist like you do with a yo-yo. If it reels out to the floor the tension is too loose. If it doesn't drop at all it is too tight.

3. Now make sure you use the right type of needle. For cotton you want a "sharp" and for reg. weight cotton about a size 10 maybe 12.

Now take a piece of strap cotton material like you're going to sew a seem and sew with a wide zig zag. Example the top side and then the bottom. They should appear identical, flat with needle holes at each side where the thread disappears to the other side. You should see no loop where the threads over lap each other and the material should not be puckering in the middle.

If that is not what you see then think this way:

The TOP side of the stitch is effected by the BOTTOM thread. the bobbin tension.
The BOTTOM side of the stitch is effected by the TOP /needle tension.

Adjust the responding tensions until the stitch looks the same on both sides. Now you are ready to sew your cotton! :)

The bobbin thread is loopy on the under side of the fabric. I tried adjusting the tension setting but it didn't help at all.


Loops stitches on the underside is typically from the TOP tension being too loose, however it can also be the bobbin tension is too tight, or a problem with the needle. I would check them in that order.

Hold the bobbin thread and let the bobbin dangle. A slight shake of your hand should allow the bobbin to move downward (lets more thread out) but not so much that it just drops to the floor. When you put it in again and try sewing look at the top stitches. Do they look overly tight? THen the bobbin tension is too tight. The stitching should look the same top and bottom with no loops.

If both tensions seem to be alright check to see if the needle is: 1. the right size and type of the fabric 2. not bent

That should fix your problem :)

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 :)
