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

Bernette 715. Why does top thread keep coming out?
The quilting is thick and the thread isn't being pulled into the work by the bottom bobbin tension, or the top tension is too tight.

I can’t get the tension on my Bernina 65 correctly set. There are three dials on the top that I find no reference for in the directions. PLease help
The manual for the Bernina Bernette 65 are available from the manufacturer here: https://www.bernina.com/getdoc/6d2754b8-af09-4edb-a6a6-7a4c57965b8d/bernette-55-65-80e-90e . The three dials, from left to right, are thread tension, stitch length, and stitch width (page 9, page 12 of the PDF). See page 24 (page 42 of th ePDF for the pictures of the appearance of the correct tension versus the incorrect top thread tension. For best tension testing, use different color top and bobbin threads. Do use the same thread type and needle appropriate for your fabric and use scrap from that same fabric. In general, if the top thread is visible on the under side of the stitched fabric, increase the tension (turn the dial to a higher number). If the bobbin thread is visible on the top of the fabric, reduce the tension (lower number). Make sure that the machine is properly threaded. (Make sure that the presser foot was up during threading and is raised when you adjust the tension dial.) Start with the tension at 4 and change the tension in small steps. (Do not turn the dial more by 0.5 before stitching a line to test the tension again. You want to avoid over-correcting.) When the tension is correct, the top and bobbin threads will meet between the two layers of fabric for a normal seam.

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 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.
