SOURCE: Thread tension?

I own this little gem of a machine. It definitely sews a perfect stitch. I'm assuming you own the green 3/4 size machine as denoted by your product number. The half size blue one pictured is incorrect.

Anyway, this machine sews a perfect stitch, due to the oscillating bobbin. Most sewing machines with rotary (drop in) bobbins don't have an easily accessible bobbin tension screw, which means your fabric is usually slightly puckered. Fiddling with only the upper tension helps very little. This frustrates me to no end for sewing long curtains, clothing side seams, etc. Wrong tension causes them to hang with puckers, making them look awful. With the Hello Kitty 3/4 size Janome, there is a screw on the bobbin case which allows you to adjust for every thread diameter perfectly. Always a perfect stitch, if you take the time to adjust this screw.

To adjust the bobbin for a perfect tension, load the bobbin into the bobbin case and thread it through the guide. Holding only the thread between two or three fingers, let the bobbin case dangle below. This will be slightly difficult, because the bobbin will want to fall out of the case. Don't worry, just don't move it around too much and it will stay in long enough for this test. If the metal bobbin case slowly drops lower, unwinding thread as it goes, the thread is too loose. Tighten the screw on the side of the bobbin case a little (about a quarter turn.)

If the bobbin case seems to be dangling firmly, give the thread a gentle tug, lifting up fairly quickly. If it doesn't release a couple of inches of thread, it's too tight, loosen the screw. You know the tension is perfect when a quick, light tug of the thread releases a couple of inches of thread.

sarah if the top tension is to tight it might slip stitches but as always when there is a problem with stitching you should change the needle and make sure it is in right.
Taking the needle plate of and cleaning with a fine brush around the bobbin and feeders will help and should be done regular.

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

Please TRY the solution BEFORE giving your considered rating.
Specific detail on bobbin case adjustment (with picture) near halfway down reply, the remainder will help you achieve a balance of top and bottom tensions.

Ensure that all is clean and free of lint and jams, this is the most likely cause....now for tension troubleshooting .......

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 consistent diameter with good thread, and less compensating to be done by your tension plates and less thread breaks

What is the proper tension number for a normal straight seam


Usually, the midway point of the upper tension dial is the standard factory setting. However, machines change with age and use. The correct tension is when the top and bobbin threads meet in the middle of the fabric. (However, that means you should test/reset the tension whenever you change projects because different fabrics may require a different tension setting.) Don't be afraid to adjust the top tension. You know where it started, so if you turn the wrong way, you can always undo it.

Adjusting the bobbin tension is usually a last attempt as it is very sensitive and is difficult to undo. Bobbin tension very seldom requires adjustment.

HINT: When threading the top thread, ALWAYS RAISE the presser foot and rethread from the beginning. Install a brand new needle when beginning a new project, after 8 hours of sewing, or if the needle strikes something on the machine. (A new needle is very inexpensive when compared to frustration, damaged fabric, or machine repair expenses.)

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.

What is the tension disc and how do I draw thread into it?


Make sure the thread is pulled into the disc - if you just place it and are not firm the thread will not be in place correctly - this disc puts the correct amount tension needed to sew your garment

You should see numbers (on the disc or at the side - if on side a arrow to set at the numbers ) the higher the number you set the greater the tension on the thread - well that's for a Jones machine it may be reverse on yours!

you can purchase a new tension dial here
http://www.sewingpartsonline.com/tension-brother-vx-800-sewing-machine.aspx for your machine. This may be simpliest solution.

there is also a manual on that site http://www.sewingpartsonline.com/instruction-book-brother-vx810-sewing-machine-instruction-manual.aspx but I can't see images to know if it includes an exploded diagram of the tension dial.

Stitches form loops below te work. i tried to tighten the thread tension & a used the pressure regulator but to no avail. kindly help


If you are getting loops on the underside of your seam, it is usually the top tension that is at fault. Check that the thread is under tension by pulling the top thread just before it goes into your needle with the pressure foot down (most machines don't apply tension until the pressure foot is lowered).

Check the tension dial - is it set to the middle number? usually 5 if the dial goes from 1-10?.

You can also clean between the tension discs - turn the dial to zero and slide the salvage edge of an offcut of light fabric between the tension discs to remove any build up.

Thread will shed particles of dye and filaments as it goes through the tension discs so you need to clean this area regularly.

Now rethread everything, check the tension dial is back to 5 and try again.

There is also good general sewing machine maintenance guides at www.sewing.about.com which I find very useful.

Need to know how to set the tension to sew hems on


Re-thread the machine and make sure that the needle is in properly. The tension would not cause the thread to break.



If it is not working, what is the machine doing? Try re-threading the machine again, check the needle to make sure that it is in correctly. There are no set numbers for tension- it is a feel, push, pull. If you could e-mail me back with a better description of what the machine is doing or not doing,

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.
