SOURCE: burnette 65 bobbin tangling can't adjust thread tension

Have you replaced the needle with a new one? Your needle may be bent or in wrong, or the wrong size. You may have a bad needle. Check that the upper thread path is running freely and is not tangled or wrapped around anything. Make sure that the bobbin is unwinding in the correct direction as well, most bobbins, this is clockwise as the bobbin faces you. If you are using inexpensive thread, it could be the thread that is the culprit. Uneven thread in the needle will not flow through the needle properly, and cause bunching as well. Save it for the bobbin, and use good thread in the top.

SOURCE: I am loading bobbin and can't thread cotton

Open the manual and lay it right next to the machine.

Raise the presser foot and thread the machine - always have the presser foot up for this proceedure - according to the written instructions. Same for the bobbin.

The tension should be set according to the recommendations in the manual.

Once you get the machine set-up and sewing.

Refer back to the manual as you read and test each and every feature of the machine.

This will help you become better acquainted with this particular model.

It matters not how new you are to sewing or if you started sewing when Eve needed to switch from fig leaves to textiles - everyone needs to read and apply the instructions provided in the manual. Graphics and pictures are helpful but sometimes miss important steps.

Best wishes for many successful projects.

Our Bernette E90 timing was off due to a jam (design flaw I think)...Instructions on how we fixed it.

1. To correct timing, tip over machine and unscrew inspection plate.

2. Find the gear and unscrew the 2 grub screws so the gear is free from the shaft

3. Turn the main sewing machine handle to manually get the hook (pointed piece) of the housing (see arrow) to be directly behind the needle

4. Hold it the tightly, and turn the handle again, the needle should be able to go up and down while holding the hook in position.

5. When the needle is at it lowest and starting to move back up and the hook is directly behind tip the machine over and tighten the 2 grub screws on the gear underneath.

6. Replace inspection cover and you’re done

How do I turn off THE BOBBIN winder on a Bernette 65 sewing machine?


The bobbin spindle needs to be moved to the left in the slot to disengage the winding mechanism. (It may be easier to do this with the bobbin on the spindle. The bobbin and spindle should be moved to the right after putting the bobbin on for winding.)

The directions and pictures for winding the bobbin are on page 30-31 of the manual. The manual is available from Bernina on their support page for the out-of-print Bernette machine manuals: .http://www.bernina.com/en-US/Support-US/Out-of-Print-Manuals/bernette-manuals/Bernette-Sewing-Machines . The direct link to the Bernette 65 manual is here: http://www.bernina.com/getdoc/6d2754b8-af09-4edb-a6a6-7a4c57965b8d/bernette-55-65-80e-90e .

I hope this helps.

Bottom tension on my bernette 50 sewing mechine don't know how to fix it.


Bottom tension is controlled by the bobbin case. First, ensure that the thread is wound tight onto the bobbin (should not be spongy when you push your fingernail into into it) Looking at the open side of the bobbin case, insert the bobbin into the bobbin case (so the thread winds off in a clockwise direction) and feed under the 'tension finger'. If you now hold the end of the thread, suspending the bobbin and case from it, the assembly should not drag any more thread out of the bobbin case. If it does, the small screw on the tension finger needs to be tightened slightly. If the assembly does not drag out any more thread, give the thread a little upwards tug. The assembly should slide down a little.If it does not slide, the tension finger is too tight - loosen it a little.
Insert a NEW needle, make sure the top thread is correctly threaded and tension is set at the 'normal' setting (as per book) ..... .... try sewing a sample. Note: using 'cheap' thread will cause all sorts of tension issues as well as fluff up your machine fast - avoid it!
Good luck

My Bernina Bernette 65 has a problem with the thread bunching up every 10-15 stiches on the bottom. Some of the thread stitches on the bottom of the fabric are in a straight line, and then the thread will...


try a new needle--one that is for the fabric being sewed
then try to adjust the top thread tension again, if the stitches remain loose and the tension won't adjust then the tension knob needs to be checked to see if there is something wrong with it.
also check to make sure the bobbin is inserted correctly into the bobbin case, if the bobbin is not turned the right way in the bobbin case the sewing machine will not stitch correctly.

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?

I have a 600 also...have you changed brand of white thread? Sometimes it can be the design you are embroidering that will bring bobbin thread to the top. I use the prewound bobbins--very thin thread & tightly wound.

Pfaff varimatic 6091 sew a rag quilt with jean and flannel,I can't get my tension right it seems to be funny on the bottom stitch,where shoulf the top tension be set at 4 1/2 ,when do I adjust the bobbin...


Hi! The bobbin tension rarely needs to be adjusted. First, make sure you're using the appropriate size needle and thread for your fabric (I'd probably use either a 'denim' needle or a universal size 14) and also that the upper thread and bobbin are threaded absolutely correctly. These can throw off the tension! Also, take the time to clean out the bobbin area. That can throw your stitch off also.

If the stitch on the bottom is loose, so that you see the top threads, then the top tension is too loose. If the top stitch is too loose and you see the bobbin threads on top, then the top tension is too tight.

It helps to thread the machine with different color thread on top and in the bobbin, and then stitch an inch or so on the same type of fabric as you're using in your quilt. Check the stitch. If you need to adjust the top tension, make sure the pressure foot is down! Adjust a little, stitch a few inches, and check again. Repeat until you don't see any (or very little) bobbin thread on the top or top thread on the bottom.

If you go through all these steps, and the bobbin thread is still loose (and you've tightened up the top tension), then there is a tiny little screw on the side of the bobbin case that you can use to adjust the bobbin tension. Turn the screw just a little bit (less than a quarter turn), stitch, check, etc. Once the bobbin tension is set, you shouldn't ever have to change it.

Let me know if this helps, ok?

Happy sewing!

Top color thread showing on bottom of embroidery on a Bernina Deco 330 embroidery machine


Upper tension is too loose or lower tension is too tight.This might be a good thing. It depends upon how much it is pulling the thread under. A perfect tension on embroidery is about 2/3's lower thread and 1/3 upper thread showing on the bottom.
