Sewing Machine Thread Tension problems

Hi, I have a Kenmore 385.15616
I'm trying to sew upholstery fabric and the tension on both the top and the bobbin seem to be off. The bobbin thread bunches up underneath the garment and the thread on top pulls through too quickly, making it skip off the spool and reel around the spindle.

I've tried various tension settings and stitching. It works fine for non-upholstery weight fabrics. Ideas?

What size needle are you using?

Posted on Dec 31, 2008

  • David Robinson Dec 31, 2008

    Yes it can make a difference.You should be using a green needle, size 18(110), for upholstry fabrics. Also when sewing heavy material it's a good idea to lubricate the machine before you start. Let me know if this works for you. Please rate me so I know if I helped you. Thanks.

What are the correct top & bottom tensions for this machine?


Both tensions are preset at the factory. Normally, the bobbin tension is the last one to adjust. Most often tension adjustments are made to the top thread. The factory standard setting for the upper thread is the midway point between the high & low numbers, however, each machine is different and may need slight readjustment.

The tensions are correct when both, the upper and bobbin, threads meet in the middle of the fabric. Tension is not static. Differing fabric weights, thread, or needle sizes may necessitate a change to tension. Lighter weight fabrics like chiffon will require a different tension setting than heavy fabrics like denim. Always test first on scraps of the fabric you plan to sew. Get the tension set the way you want it before you begin sewing your project.

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.

I have a Kenmore sewing machine - 12 stitch model which I bought in the 70's. I am having a tension problem and can't seem to fix it. What is the normal setting for the top, and bottom?


Hello

Load your Kenmore sewing machine with the right thread and bobbin thread for your project. If you use the wrong weight thread for your fabric or severely uneven weights of thread, this can cause the appearance of a tension problem when it is, in fact, a thread weight problem or a problem with your sewing speed. If you go too fast, you will break the thread. If you go too slow, you can cause loops. Uneven pressure can cause stitches to vary greatly.

Test your Kenmore sewing machine's tension by sewing on a piece of scrap fabric. If your tension is way off, then test on some basic cotton or a firm blend simply to get your tension right. Do not try to start adjusting your tension on silk or leather. Get a base adjustment on a more standard fabric first.

Look at the top threads and bottoms threads. If the tension is off on one side, it will usually affect the other side slightly. So select the side that looks more maladjusted to start adjusting the tension.

If the top thread is too loose or too tight, you will need to adjust the tension dial. This dial is usually located a few inches above the needle on the Kenmore machine body. Usually, your machine will have markings to indicate which direction tightens the tension. If these have worn off over the years, watch the dial as you turn it. If it appears to move toward the machine body, then it is tightening.

If the bottom thread is too loose or too tight, then you will need to open the door to the bobbin case. On some Kenmore models, there is a little screw near the bobbin case that can be adjusted slightly to adjust the tension. On other Kenmore models, there is a screw on the bobbin case itself--not on the bobbin, but on the bobbin's casing. This will also adjust the bottom thread tension. Adjust the bobbin thread tension to make slight changes.

If the thread is looping severely on one side, the thread weights might be off. For instance, look to see if you have a lightweight thread on the bobbin and a heavyweight one on the top. If the thread keeps breaking, the top tension or bottom tension could be too tight or the thread is too lightweight for the material you have selected. Check your combination of threads and material. Also make sure you are using the right weight needle and the right foot for the sewing step or project you are working on.

If your Kenmore sewing machine's tension is off severely or if you have not used your Kenmore in a long time, then you might need to take your machine in to be serviced. Sometimes, the inner parts need to be oiled or the entire machine might need to be cleaned and calibrated by a professional. If you sew a great deal or if your machine sits idle a lot, both situations will usually require some servicing to keep your Kenmore sewing machine and its tension in perfect working condition.

I am trying to sew a boat canvas top with sunbrella canvas. my top stitch is beautiful but the bottom stitch is loose and messy. Is this just a tension adjustment and if so what should I be adjusting?


Try adjusting the top tension dial to tighten up the loose stitching on the underside. Generally if you have loose threads underneath, its the top tension and visa versa.

However, if you are using a thread heavier than normal sewing thread through the needle and bobbin (which you probably need for this canvas) then the machine may struggle. I've sewed vinyl seat covers and gave up with my domestic machine and purchased a second hand industrial Singer machine 20U to cope with this heavier weight textile. Generally for anything heavier than upholstery fabric a domestic machine may not be strong enough.

Tension is too tight on my sewing machine,,need to know the settings to go with which seam. singer 724 graduate


Hi. As a rule of thumb, once the tension is balanced on your machine, it shouldn't need adjusting. It's not something you adjust for each different type of seam or fabric (again, rule of thumb!). (Certain kinds of sewing, like free motion embroidery or when you use rayon thread, require particular tension adjustments, but for ordinary sewing, you shouldn't have to mess with the tension that often.
If the top tension is too tight, your top thread will be loose and basically just sitting on top of the fabric. You need to loosen it up so that the bobbin thread can pull the top thread down into the fabric.
Let me know if this helps, ok? I'm going to post a tip on adjusting tension so please check that out.
Happy Sewing!

No bobbin tension


If the thread is loose on the bottom of the fabric, it's actually the top thread is too loose. Think of 2 little elves playing tug of war in your machine, one on toip and one underneath. If you have loops on bottom, the top needs to pull harder (tighten top tension)

you have your thread tension too tight that's why it is pulling the bottom stitch all the way through it looks good from the bottom but not good on top. Its pulled the stitch all the way through the material.
I had my own upholstery shop 18 yrs and tension gets you every time.Just loosen the top tension.

Kenmore 15343 incorrect stitching


When you see the bobbin thread on top of the fabric this can be on e of 2 things usually. 1) thath the top thread tension is too tight or that the bobbin thread loose. Remember the saying righty tighty, lefty loosey. If you have adjust the top tension and it has helped just not enough perhaps you need to try the bottom a small screwdriver to turn the little screw on the outside of the bobbincase may do the trick. only small adjustments 1/4 turn at the most at a time to the right to start with.

Sewing with drapery material


Switch back to regular thread. Upholstery thread is used for seams that will get lots of stress (as in upholstery; although I use regular thread in upholstery and have no problems). For draperies, regular thread is fine.
