Question about Bernina Activa 140

1 Answer

Bernina Activa 240

I just purchased a Bernina Activa 240 and when I try the blanket stitch, it is bringing the lower thread up. I know this would normally be a tension problem, but it is on the standard #4 setting. I have re-threaded the machine a million times... not sure what to do next, other than drive an hour back to the Bernina dealer & get it fixed. I have a Bernette 80e, so I am somewhat comfortable with these machines.

Any suggestions would be helpful.
Thanks!

There is also a tension adjustment on teh bobbin. It's just a little screw. Turn it about 1/4 to 1/2 turn and try again. Adjust as needed a little at a time.

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.)

I would like to know how to set the machine up for polyester/spandex material


You need a ball point size 70 or a jersey 70 if you can get it. Stitch length 2.3 to 2.5. Re tension, just normal tension setting. If the machine is sewing an evenly balanced zigzag on regular cotton fabric, then tension is fine. If you find the straight stitch on your fabric pops under stretch, then try using a very small zigzag to put some flexability into the seam.

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?

My tension is bad. I've tried adjusting, but no success. The lower thread can be seen between the stitches on the top side. How do I correct this.


I'm not completely familiar with your machine, but I would suggest tightening the bobbin tension on your machine. Check you owners manual for instructions. The symptom you've described is either top tension too tight or bottom tension too loose. Good luck!

I can't find my Bernina Serger 800 dl manual - how do I thread for a 2 thread rolled hem, and do I need a upper looper cover and that the heck is that anyway?? Thanks


From what I have read this manual is less than desirable. Neither is the one for the brand that I have.

You may have better guidance if you purchase and use Nancy Zieman's "Serge with Confidence". I have found it very helpful.

For the two thread rolled hem, the looper cover is used to "trick" the looper into "thinking" it is threaded.

On my serger (not a Bernina), this is referred to as a "subsidiary looper". It is a spring type mechanism that fits in a small hole at the top of the upper looper.

You use a rolled edge presser foot; right or left needle; stitch length @ normal or wider; stitch length @ 1mm for the left needle/0.5 for the right needle; differential feed @ normal; needle tension - tighten; lower looper tension - normal or looser; two thread looper cover - engaged.

Test and adjust the tension as needed before making the rolled hem on your garment.

I hope this helps.

Bernina 1008 - tension problems


Make sure the presser foot bar is UP before you thread the machine, otherwise the thread doesn't connect propertly with the tension discs. Top thread should reel-off in clockwise direction.

either the bobbin thread is not in the lower tension or the lower tension is too loose or the top(upper) tension is too tight.
