Question about Necchi Sewing Machines

How do I set the tension on a 40 year old Nechhi 359? I haven't sewn in years and can't locate the manual. It quite often skips threads and won't catch the thread under the slippery, thin fabric. W

I don't remember what all the numbers on the thread tension dials mean? I know this sounds really simple, but help me out, please! Thanks to all old ladies out there who can sympathize!

Hello Sharon, Usually the higher the number on your tensioner means more tension on the thread. I would start out at 3 1/2 and go from there.

SOURCE: sudden knotting under fabric

I have an Elna 2005 machine and had a similar but opposite problem whereby the tension up top was too tight - thread wouldn't pull smoothly. I found adjusting the feed dog lever slightly helped the stitches a lot, even though the needle tension up top is no better. Hope that helps! :-s

SOURCE: thread continually breaking in lower looper needle

I was having this very same problem with my lower looper . I had been using the one needle stitching all afternoon and I was doing quite nice stitching. then I decided to put the right needle back in and do some overlock stitching and guess what I spent the next two hours fighting the looper problem. I had completely re-thread this machine at least 20 times now. I decided to take the needle out and re-insert it and re-thread it one more time (right lower looper- then upper looper- right needle- then left needle) was careful to pull all threads to the back and under the presser foot for about 6 inches.
Held on to the thread, lowered presser foot and did the chaining stitch. BINGO it didn't break, tried it with a piece of cloth and Perfect stitches. I have a Babylock BL402 and used tension settings left to right
4-3-3-3 and default settings for the rest.
Hope this helps someone someday.

if thread is good quality you may have a sharp groove in your needle plate hole from needle breakage. if so, polish with emery tape.

SOURCE: Huge loops on back of fabric!

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 !

How do I adjust the tension for straight sewing?


First, be sure you are using a brand-new needle and that the needle, thread, and fabric are compatible.
All About Needles

When you thread the upper thread, be sure the presser foot is ALWAYS RAISED so the thread will seat properly in the tension disk. Also, confirm that the machine thread pathway is correct.

Remember that when fabric types/weights are changed, the needle/thread should be changed accordingly. (Needles should be changed often to attain the best sewing experience and minimize unnecessary frustration.) The tension may also need to adjusted. Tension is not static. It should be adjusted to fit the project being sewn. Unless one continuously sews with the same fabric, thread, and needle type would the tension adjustment remain at the same setting, but machines do change over time so a tension setting that worked last year may not look the same this year.

The factory standard tension setting is the midway point between the high & low numbers. However, please understand that machines vary and that sometimes this standard setting may change with time and use. The midway point should only be the beginning point and is most likely suitable for medium-weight fabric. Also, usually the bobbin tension does not require frequent adjustments unless a particularly heavy- or light-weight thread is used in the bobbin--sometimes the bobbin tension will get out of whack requiring adjustment (consult the owner's manual or search the internet for instructions for adjusting bobbin tension). In the majority of cases, the tension adjustment is made to the top thread.

Test your straight stitch on your fabric (may be helpful to use a different color thread in the bobbin so it is easier to see any tension issues). If the bobbin thread is popping up to the top of the fabric, loosen the upper thread tension. If the upper thread is looping or showing on the bottom of the fabric, tighten the upper tension. Keep adjusting until the upper and bobbin threads meet in the middle of the fabric.

FWIW, the same process would be used for zig-zag stitching. Just make sure that the tension is not too tight or it will cause the fabric to pucker (or tunnel).

Machine is "hopping" when I use zigzag program. It seems like there is a problem with the mechanics in the over thread ?


Not quite sure I understand the problem. However, the following may be helpful:

First--install a brand new needle. Old, dull, knicked, bent needles play havoc with stitching. Needles should be replaced frequently (it is the least expensive and easiest resolution to sewing issues). Also be sure that the needle & thread are compatible, ie the thread is not to large for the needle's eye...

Second--one of the primary resolutions to upper thread issues is making sure it is threaded properly. Remove all the thread. RAISE the presser foot to release the tension disk, then rethread from the beginning. Verify that it is threaded through all the guides per the owner's manual.

Also, thread skipping sometimes occurs due to the type of fabric being sewn, ie knit fabrics will tend to hold onto thread, therefore it is important to use a needle suitable for the fabric.

All About Needles

One other thing to check is that the thread coming from the thread spool is not snagging on something. This will frequently cause thread to unwind in a jerking motion.

What is the tension supposed to be on my homemaker fy2300 model sewing machine i have misplaced my manual and can't seem to get the tension right?


The standard factory tension setting for most machines is the halfway point between the high and low number. The upper tension is not meant to be static, ie, the tension adjustment will change depending on what is being sewn.

The tension is correct when the upper thread and bobbin thread meet in the middle of the fabric.

My sewing machine needle (very new one) keeps jamming every couple of turns of the needle - and the thread is very loose and loopy on the fabric. It makes a jarring noise


not quite sure how needle is jamming. I have had them break, had thread ball up underneath and caused needle to jam. Question is the needle in the right way, ie the flat side in as per manual, generally the flat side faces away from you. Sounds like your tension is not quite right if the thread is looping. Loops on bottom, bobbin tension, on top sewing machine tension

I have Usha allure,sometimes it gives skipped stitch,and sometimes it gives bunches at the bottom. If I use thin thread for interlock, it dosnt accept, what is the solution?


Sounds most likely to be either thread tension issue - check bobbin tension OR dull / bent needle - put a new needle in suitable for fabric being sewn. Use good quality thread.

I love my machine except when trying to free motion quilt. No matter how loose I set the tension it still pulls the bobbin thread to the top. I also have trouble with the thread breaking and stitches...


Properly balanced tensions are critical. The lower bobbin tension must be tight enough to pull the knots down. To which number is your upper tension set? It should be around three. Skipping stitches is an indicator of hook timing and hook/needle clearance issues.

Once I set up my design card and select design, the needle moves


Hi, and welcome to FixYa. If I understand your problem, the needle goes in and out of your fabric, and the embroidery hoop moves, but the machine does not actually start embroidering your design right away....did I get it right? If have time to answer a few questions, I can give more accurate instructions.

  1. How long have you had your machine?
  2. How long have you been doing machine embroidery?
  3. Do you have a manual for your machine?
  4. Look at the back side of your design - do you see lots of bobbin thread, or hardly any?
  5. Have you taken lessons for your machine or for embroidery?
  6. When your design is finished, can you where the machine skipped stitches?
Here a couple of things you can try (if you have already):

  • Make sure you use an embroidery needle, not a universal. In most cases, you should use a size 90. Change your needle after each project. A blunt need can cause your machine to skip embroidery stitches anywhere in the design.
  • Rewind or replace your bobbin. Make sure you use bobbin thread in your bobbin when you embroider - it is thinner and gives you better tension. If pre-wound embroidery bobbins are compatible with your machine, I recommend that you try one and compare the result with designs sewn using the bobbin thread you've been using.
  • Normally, you should loosen your tension a little bit when you embroider. When you look at the back side of your embroidery, you should see more bobbin thread than embroidery thread.
I owned an embroidery business for several years, and I have six different embroidery machines of my own - so with a little more info from you, I think I can help.
