Question about Bernina Activa 140

1 Answer

12 wt thread

I have a Bernina Activa 140 and need to use 12 wt thread in both the upper thread and the bobbin, stitching 2 layers of cotton fabric and a layer of cotton damask together. I have tried several needles types and sizes including size 80, 90 and 100, different tension settings for upper thread and bobbin thread and tried lengthening my stitches. The stitches just won't come out nice and strait and look a bit wobbly. Has anyone had success with using 12 wt thread in this manner and what settings and needle gives nice stitch results?

12 wt thread generally will not work well in the bobbin...


"Aurifil 12wt Thread
Aurifil 12 wt thread is ideal for hand quilting, big stitch hand quilting and machine quilting. 12 weight thread creates a more defined and often primitive look. It's great for designs that use a longer stitch length if using a machine. When machine quilting with 12 wt thread, use 40 wt in the bobbin, increase your stitch length, lower your tension, use Topstitch size 90 needles and stitch slowly."

SOURCE: i have an 1130 bernina

The 1130 does not have a consumer adjustable presser foot. Check to be sure you are using the correct presser foot .Some feet are slightly different in height which is how the pressure is regulated. If this is not your problem it will need to be seen by a technician.

SOURCE: Why won't my Bernina Activa 140 sew the blind hem stitch?

Are you absolutley sure you're not getting a problem with stitch formation on, for example, wide zig-zag. Check again, using a different colour top and bottom and make sure that the stitch is being formed properly with only the top colour on top and bottom colour on the bottom. It sounds as though the bottom loop is not being picked-up by the hook properly. Make sure you've thoroughly cleaned-out any fluff under the stitch-plate and remove the hook/shuttle and give the hook race a good clean and give it a single drop of oil, even if you've got the lightweight part-plastic hook/shuttle fitted.

SOURCE: Bernina activa 210 won't zigzag and has bobbin issues on straight stitch

it's very possible that the machine is slightly out of time & needs to be service at a sewing machine shop
is the fabric & thread & needle compatable with each other?
did you use every thread guide when threading the machine?
is the bobbin in correctly?
is the bobbin warped?

Bernina activa 130 tension loose after needle breaking into bobbin area


Is it the bobbin tension that is very loose? Try tightening it. Also check that the bobbin has been installed in the bobbin case, turning the correct direction and that the bobbin tension is threaded properly.

Bobbin Tension How and Why Tension is Adjusted

Understanding Bobbin Tension

Understanding Thread Tension Threads

If it is the upper tension that is loose and creating "thread nests" under the fabric, the machine is either misthreaded or possibly the thread is not seated completely in the tension disk.

Remove the upper thread from the machine.
ALWAYS RAISE the presser foot and rethread the upper thread from the beginning--verify the thread path is correct.
Set the upper tension to the midway point between high & low number (the factory standard--although it may need tweaking later for your particular machine).

Retest your machine. Hopefully, the issue has been resolved. If not, it may need service.

Why is the stitching on the bobbin side of soft fabric uneven


Is it the upper thread that is looping under the fabric? If so, that's what is called thread nesting or bird nesting. It is usually caused by it not being threaded correctly or the tension is off. Most likely, it is because the thread is either not in all the guides, the thread path is incorrect (it may have jumped out of the take-up lever), OR (most frequently) the thread is not completely seated in the tension disk.

#1--install a brand new needle that is compatible with the thread & fabric you are sewing. All About Needles

#2--remove the upper thread. Always raise the presser foot and rethread from the beginning making sure to follow all the guides and the thread pathway.

Set the upper tension to the midway point between high & low number and test. Re-adjust tension as needed. If the upper thread is showing too much on the underside of the fabric, the upper tension is too loose. If bobbin thread is showing on the top, then upper tension is too tight. Correct tension is when both upper & bobbin threads meet in the middle.

I have a Bernina 145 S activa and I can't get my satin stitch to work , it brings the bobbin thread to the top , what can I do ?


Do you use stabilizer when you are satin stitching? I had a teacher who also hooped the fabric with a spring-loaded embroidery hoop (turned upside-down under the presser foot so the fabric is flat against the needle plate) that would keep the fabric taut.

It is not uncommon for bobbin thread to rise to the top when doing embroidery, satin stitch, etc., especially if you are using lighter-weight thread than usual. You would normally loosen the upper tension so the upper thread will sink into the fabric. However, if loosened upper tension is not doing enough, you may need to adjust bobbin tension when doing embroidery, applique... You might try tightening the bobbin tension just a smidgen to get the bobbin thread to stay below the fabric. Be sure to mark the bobbin case before making any adjustments so you can return it to the original setting when finished with the satin stitch. (If you do a lot of satin stitch or applique, etc., you may want to invest in a separate bobbin case that is set up only for doing that kind of work--saves having to alter the bobbin tension frequently.)

Bernina 1080 pleats the fabic of 1 layer on zig zag setting.I am trying to do the "cheats way " of gathering.Have adjusted the top tension ,changed thread/ needle.What can it be?


The fabric is tunneling? The pleat is forming the length of the line of stitches? http://crazylittleprojects.com/wp-content/uploads/2013/01/Z4.jpg Loosen the upper thread tension and increase the presser foot pressure and/or choose a flat soled foot, not an embroidery foot and/or add paper or other stabilizer on top of the fabric.

Or if the stitches are gathering up as you sew, go with it... that's what you're going to be doing anyhow, right? You can increase the amount of gathering by parking your thumb or forefinger hard against the needle plate behind the presser foot and allowing the fabric to pile up--- this is called "crimping" or "ease plus" and is commonly used for easing princess seams or sleeve heads. If it eases too much, clip the seam threads here and there and pat the fabric back out a little flatter, till it fits.

PS: If you like Gutermann poly threads, check the prices for Mara 100 at Wawak.com or similar pro sites. At Joann Fabric prices, you get an $8 spool of thread for $2.50 or less. Good stuff.

I need to find out how to set up my machine for polyester/spandex material.


For spandex you will probably want to use a size 70 needle for stretch fabric. You should be able to leave your tension settings on standard tension but may need to go for a slightly shorter stitch length.
try stitch length of 2.5 or 3
tension of 3.5
check your bobbin tension, to do this thread the bobbin and suspend it in the air holding the thread. If the bobbin falls to the floor the tension is too loose. If the bobbin hangs in the air and you give a gentle tug on the string the bobbin should slide along the thread an inch or so. If it doesn't budge it's too tight.

When you say the thread is not the same on top as the bottom do you mean you are using different threads or that the stitches are coming out different on the top to the bottom of the fabric?

My Bernina Activa 140 (12 yrs. old,first time to have any trouble with it) has stopped stitching properly. The top thread looks normal but underneaty(the bobbin thread I guess) is just giant loops an


Almost every time this will be due to the machine being not threaded correctly. I've been sewing for 45 years and still mis-thread my machine occasionally. It's also possible that the bobbin thread didn't seat quite right when you put in the bobbin. Or, I've had mine do that if I didn't quite get the presser foot lever down completely. (working with heavy fabrics usually)

If that is not the case here, try replacing your needle with a new one, as it might have developed a small burr, and be certain that it's the correct needle for the fabric. Sometimes it can also be that the needle is in backwards. Also, cleaning it, (the bobbin area), out thoroughly by using a soft brush and some canned air can do wonders for it. Then use a drop or two of sewing machine oil where your manual indicates it to go in that area.

If none of that fixes the problem, let me know and I'll see if there is a problem specific to your machine that can happen.

Happy Sewing! :)

The bottom thread on my Bernina 140 jams


Try pulling more thread out before you begin the seam - about 6". If you can hold the threads while you take the first few stitches that helps too.

Whenever I zig zag my machine skips stitches.


Hello,
Try these solutions.

* Re-thread your needle
It may be threaded incorrectly (backwards).

* Reinsert your needle
Make sure it goes all the way into the holder and that it’s positioned correctly – usually with the
flat side away from the bobbin, but consult your machine’s manual to be sure.

*Change your needle
Your needle may be blunt, bent, or otherwise damaged.

*Your fabric may require a different needle. Generally, heavier fabrics require larger needles and
thinner fabrics, smaller needles. You may also need a larger needle if
you’re sewing through many layers of fabric. And make sure to use a ballpoint needle for knit fabrics and a sharp needle for wovens (or a universal needle for either).
And make sure your needle is appropriate for the type of thread you’re using.

* Adjust the pressure of your pressure foot
It may be too light for your fabric.

* Change your thread
If your upper thread and bobbin threads are different types, try using the same thread for
both. And use a good quality, brand name thread.

* Adjust your thread tension
It may be too tight or too loose.

* Re-thread your machine
It may be threaded incorrectly.

* Change your needle plate
Try switching to a needle plate with a smaller hole (a straight stitch needle plate).

Important: If you change your needle plate, check to make sure your needle aligns perfectly with
this smaller hole before starting to sew. A misaligned needle could hit the plate and break, which
could be dangerous. And make sure to change your needle plate back for zigzag and other wide
stitches.
I hope this helps you.
