SOURCE: thread or bobbin tension

Thread tension. Beware of adjusting the bobbin screw. Pfaffs maintain their tensions just fine without adjusting the bobbin tension, unless you're using some crazy thick or fine thread. If you must change your bobbin tension, you would be well-advised to buy an extra bobbin case, because re-calibrating your tensions after changing them can be less than fun.

Increase your top tension, and your looping should cease. I normally keep my tension around 4.5. Also make sure you're using a good quality thread, and that there's nothing in the upper tension assemblies. Sometimes a tiny piece of debris can keep the top tension from applying enough tension, so turning the machine off and blowing some canned air in there can help as well.

Good luck,

Okie Dokie..... Here's the way I see it.. The repair center was of little or no help to you . So, I will try to do my best..
First thing you need to do is unthread your machine and set the tension to 4.. Rethread the machine up to just before the needle.
When you get that far, put the presser foot down. If your thread pulls right thru easily, it is not threaded thru the tension wheel right. It your thread is hard to pull thru with the presser foot down, then it is threaded right.

General rule of thumb..
Loops on the bottom-- problem on the top
loops on the top--- problem on the bottom.
Hope this helps..

SOURCE: janome 9500 bobbin tension too tight can I adjust it

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 !

SOURCE: Can't get thread tension right on my Euro-Pro 7130

the top seam is actually the bobbin thread. dots on the underside means that the top tension is too tight. you may have a piece of thread or something gummy caught between the upper tension disks.

Adjust thread and bobbin tension


These are the instructions in the manual:
Adjusting the Thread Tension
Balanced thread tension:
Small amount of the needle thread shows on the wrong side of the fabric.
When the needle thread tension is too tight:
The bobbin thread shows on the right side of the fabric. Reduce the tension by turning the tension dial to a lower number.
When the needle tension is too loose:
The needle thread forms loops and the stitches look shaggy.
Increase the tension by turning the dial to a higher number.

However, if you have recently changed the needle check that it is pushed right up in the slot. Other thing that springs to mind is making sure that the bobbin thread is correctly placed in the bobbin, and that the chamber is not full of lint and threads.

Tension to loose and missing stitches


SKIPPED STITCHES ON A SERGER
1. Is the needle bent or worn--replace
2. Is the needle inserted correctly into the needle holder--check needle
3. Is the Serger threaded correctly--rethread
4. Is the presser foot pressure right for the fabric--adjust

use a scrap piece of fabric to sew on as you adjust the tension
when the tension is to loose adjust one number higher till stitch
looks good

Stitching is too loose on the Juno Janome Serger Model 3434D


sergers the most frustrating machines. Every time you change fabrics you go through a tension adjusting phase.

First make sure you have threaded the machine in the proper order. upper looper, lower looper, then needles from right to left. Always thread any machine while the presser foot lever is in the UP position.

If you ever break a thread... you MUST pull all threads and rethread using the proper order.

Ok that's out of the way. Pull all your threads and get out several pieces of the same fabric scrap. Thread each pathway with a different color. This will help you determine which thread is giving you fits. Sew a test strip. Which thread is loose? tighten/loosen that tension. Keep doing this until you have a well balance seam. Then clip the colored threads starting with the upper looper thread, tie off to your proper color for your seam pull the thread through and up through the throat plate. proceed in this manner with lower looper, right needle, left needle. Sew a test seam.

Good luck.

I have a VX1250. I don't know how to regulate the tension.


There is two places to adjust thread tension: the top tension device controls the top thread tension and is usually a dial or knob with numbers on the front of the machine.

Then there is some form of tension device on the bobbin; in your case I believe the Brother has a removable bobbin case with a tension spring which holds the bobbin thread firmly: the tension spring can be adjusted with a screwdriver but once set, you shouldn't need to adjust this much, just alter the top tension slightly for different weights of fabric. So start by setting top tension dial to 4-5 and test stitch a seam. Use different coloured but the same type of thread top and bottom and take a look at the seam. You want to see a balanced even seam.

Here is a link to a great info site for this:
http://www.sewusa.com/Sewing_Machine_Repair/Thread_Tension_Settings.htm

If the bobbin thread is too loose, then you probably will need to finess the tension spring on the bobbin case and adjust this slightly. The best way to set the tension on the bobbin case is as follows. Load the bobbin into the bobbin case and pull the thread tail into the tension spring, then suspend the bobbin by holding the thread tail up in the air (the dangle test). You want it to be just tight enough to hold its own weight, but still able to release thread when you pull gently downwards on the bobbin case. If it isn't doing this then take your little screw driver and adjust the screw on the leaf tension spring by ONE QUARTER TURN ONLY. Lefty looser, Righter Tighter. Then test again, and adjust again until its right.

Now test stitch again and finess your top tension to get the seam even. Remember to change the needle for each new sewing project too; this will impact tension also.

I can't seem to get the tension right when sewing. The top tension looks okay however the bottom is loose


If the bottom looks loose then this is usually a problem with top threading so rethread the machine and check that the thread has gone through the tension discs. Lower the pressure foot and pull gently on the thread just before the needle and feel if it is under tension. Is the top tension device set to the middle number setting? usually 5? Unthread the top path, turn the dial to 0 and run the edge of a piece of fabric through the tension discs to clean them. Thread shreds particles of dye and fine thread pieces as you sew so this area needs cleaning regularly.

Also a good idea to check the bobbin thread is under tension correctly and that the bobbin is in the correct way. On my Janome the bobbin thread winds off so that the bobbin turns in an anti-clockwise direction. Mine has a clear bobbin cover with a threading image to remind me of this but check yours and the manual if you have it. Janome bobbins are same top and bottom, usually clear plastic so it is easy to get it wrong sometimes.

Check out www.sewing.about.com for some good general advice on sewing machine threading and maintenance, it pays to always clean and maintain your machine regularly, use good quality threads and change your needle for EVERY project, don't try and reuse them.

Of course, if you know all this and have tried it already, then perhaps the top tension device has actually failed, if turning the dial up higher makes no differerence at all, then could be mechanic time.

I am having trouble adjusting the 4 knobs at the top and the 2 on the side. What do the numbers (1-9) signify? and how do I adjust the tension?


Check there is no thread or lint in the 4 tension units.Tension for threads (1 - 9) should be all set at 3 ... this is the factory setting.
The two knobs on the side are: Stitch length regulator, set at 2.5 for most purposes.
Differential feed is the other knob and it is used to feed left or right at a "different" rate, rather than evenly....for around arm holes etc where a curve is required.
Sounds like you need to just play with some scrap to see how things go, and get yourself a manual for the fine details.
