Question about Necchi Sewing Machines

1 Answer

My bobbin thread on My Necchi 681c keeps on jumping out of the slot, how can I stop this?

Where you put the bobbin in there is the slot bit that the thread should lie in, the needle then collects it from there, well the bobbin thread keeps on slipping out and then I have a mess. How do I stop this happening? Thanks.

SOURCE: bobbin threading

You may have put the timing out, however, try this before you despair too much......

Ensure the presser foot is firm enough for the fabric you are using and that it will not just pull through easily by hand with the foot and feeddogs together (as the needle ascends), or things will not proceed, and you will be stitching in the same spot.

Generally a setting of 3 seems to work for general purposes, but if you are using very light or very heavy fabric, a sample is always a good idea before you start in earnest....also match the needle to the work for best results.

Ensure that all is clean and free of lint jams....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 consistant diameter with good thread, and less compensating to be done by your tension plates and less thread breaks !

My bobbin and thread are constantly breaking. I have the correct thread to needle, but I don't even get one stitch before both break. Tension is on auto; should it be less or more?


is the needle in the holder the correct way ( groove in the needle facing the thread )
Is the needle eye the correct size for the thread in use

remove it from auto tension setting and adjust it your self
make sure that the top thread is between the tension plates and not around the thread behind the plates
the thread tension is close to correct when you need a bit of a pull to pull it along to the needle
is the method of threading to the needle correct as any areas where the thread reverses direction will cause it to break
what do mean that the bobbin is constantly breaking or is it the bobbin thread that is breaking
have you got the thread down the case slot and under the flat spring correctly
the bobbin has to be inserted into the case in such a manner that when the thread is pulled , it flows down the slot freely as the bobbin turns
if the direction is wrong , the thread has to move across the sharp edge of the slot and will cut easily

Keep the thread from collecting on the arm that holds the bobbin case in? My Brother LB-6800 sews quilts, and embroiders great until yesterday, The thread wraps around this small arm every time now.


Try taking the bobbin case out and re-insert. It sounds like the case that holds the bobbin is not inserted correctly. You might also try checking to be sure that the needle is inserted properly. Sometimes the needle gets loose and drops down too low. unscrew, push the needle up as far as it will go, then tighten the screw.

The bobbin case keeps getting pulled out of its slot as thread is caught on a part as it attempts to pick p bobbin thread


Did you floss the bobbin holder to make sure you don't have any bits of thread, you put the bobbin case back in correctly, have been changing the needles frequently and according to type of fabric just like regular sewing and have been using the lint brush and drops of oil like the manual illustrates?Detach the embroidery unit to use the sewing side to get the situation corrected, it's much easier on that side. Then when you have that situation corrected, run a zigzag test stitch with the thread and bobbin fil until you have a perfect zigzag going on your sample fabric sandwich--adjust the tension and you should have it.

Thread keeps breaking


Have you got the needle in the correct way around - the thread must lie in the groove in the needle. Is the machine correctly threaded? Try release the tension a bit and check that the bobbin tension is not too loose and bunching up under the needle plate. The instructions for bobbin tension setting are:- Check that the thread is tight around the bobbin. Make sure that the bobbin is in the right way around - the bobbin thread should double back on itself coming out of the bobbin holder. The bobbin tension adjustment is the small screw in the plate on the bobbin case that the thread passes under as it comes off the bobbin and goes out. This might not be exactly the same as yours but should give you an idea of the position.

I am having a problem with my Shark Intell-Sew that I've had a few times before but I've always been able to resolve it, and this time I can't. The machine jams, and the book says it's usually because the...


Many machines today have a horizontal thread delivery for the needle thread. Be sure and place the thread spool with its tiny notch on one end (the notch is used to secure the loose thread end when not in use) facing toward the far right side of the spool holder and not facing toward the left side where the thread will be guided off the thread spool into the vertical tension discs and toward the needle. Some times this tiny notch will catch the thread causing undue thread tension on the needle thread. Placing the thread spool facing toward the right seems to help the thread guide off the spool without catching in the tiny notch.

Also hold onto the needle thread and the bobbin thread, giving slight hand tension to both, for the first few stitches you make in your fabric. With the first uptake of the needle, the needle’s thread tail and bobbin tail are drawn down somewhat loosely into the bobbin case and can become tangled and jam if not held onto briefly. Be sure the bobbin thread comes out of the needle plate in the area it is intended to. After winding a new bobbin, it may help to put the bobbin in its bobbin case and just raise the machine needle by hand just enough to allow the needle to bring up the bobbin thread to the top. Give the bobbin thread and needle thread held together a slight tug so that they both lay out behind of or to the side of the needle. If you have left off the needle throat plate for last (for those machines that allow the throat plate to be removed) when placing the throat plate back on the machine, be careful to guide the bobbin thread through the hole or space in the needle throat plate so the bobbin thread lies on top the plate.

Using the right machine needle for the fabric helps too. Generally, ball-point needles work great for knits and sharp-pointed needles for woven fabrics. Using the smallest size needle that makes the best stitch for the type of fabric seems to work well for most fabrics to produce clean even stitches.

Using the best quality thread helps. The bargain-priced threads found piled in sale bins at the fabric store work great for hand sewing but not for machine sewing. Lesser quality thread make lots of fuzz as it passes through the needle and can jam the machine. Many sewing machine repair folks hate the thought of us using a can of compressed air to blow out fuzz from the tiny spaces of the machine, particularly the newest digital electronic machines, but a spritz or two of compressed air in the vertical thread slots that hold the tension discs and in the bobbin case itself, usually can dislodge bits of fuzz from these spaces. Although compressed air is not recommended for a new machine the thought is offered for you to consider for older, mechanical machines.

Bobbin thread getting jammed


kyoungblood4
Are you making sure that your pressure foot is up when you thread the upper thread? If it isn't then your thread is not seating correctly in the tension disks. It will then be loose and make a birds nest(mess) under what you are trying to sew. The other thing to check is which way you are putting the bobbin into the bobbin case, different machines do it different ways. Some want the thread to come out of the case in the same direction as the slot on the case and some want it to come off in the opposite direction.

Guest,
Probably when your son broke the needle he knocked it out of time. You will need to have a sewing machine technician to repair that.

Hope this has been helpful for you bothl Liz M
