That means your top tension is incorrect, be sure to make sure your machine is threaded correctly and that your tension assembly is working correctly,,,,,,easy fix!

When I rewind my boobin, the thread is too loose. How do I adjust it on a JUKI DNU 1541-S?

You're saying the thread on the bobbin is loose/sloppy? That would be a result of the tension placed on the bobbin during winding. Make sure you are using the correct threadpath to wind the bobbin, or the winding tension needs to be adjusted.

My Bernina 1630 A straight pin was struck by the needle and went into the needle hole. I changed the needle, but the bobbin tension is loose. Is there an adjustment for bobbin tension?

There is. It's the little screw on the side of the bobbin case. Be sure to mark its position BEFORE making any changes and turn it only 1/8 to 1/4 of a turn per adjustment.

However, if the pin damaged the bobbin case or anything else, that may need to be repaired or replaced. Sometimes, just biting the bullet and purchasing a brand new bobbin case eliminates a lot of frustration--not that expensive. Besides, I have several bobbin cases on hand because I change thread weights between quilting and regular garment sewing and it is just easier to have a bobbin case set up specifically for one use--eliminates the need to make constant adjustments to the bobbin tension between projects.

Be sure you've changed out the old needle. It could also be an easier fix by just removing all the thread and rethreading the machine again--always raise the presser foot when threading the top thread.

Please help what is a problem of a boobin to take too much cotton and make the needle to sewing in one place

1. Make sure the pressure foot isn't pushing on the material too hard. Loosen it in other words.
2. Make sure the length of stitch is above zero.
3. Check the tension of the threads (above and below). A good starting tension is four. I've sent a guide on how to adjust the bobbin thread. This is one of the usual problems that sewing machine operators have.
4. Check the size of the needle. Also, make sure you have good thread.

The cotton jam underneath the garment. How does it come about doing it ? How do i fix this on the Compal Opus machine

First thing I would try is to try to shift the handwheel on the right carefully to see if it would loosen up a little. Next thing would be to get to the screws holding down the needle plate and remove them. Remove the presser foot and the needle from it's clamp. Then slowly try to work the whole thing loose. If you can expose thread underneath the needle plate cut all that you see and try not to cut into the garment. With a little care you should be able to work it loose and out. Don't force anything if you can help it. Particularly the hook surrounding the bobbin case. Too much force and it might be shifted out of time and won't sew right once you get it all clear. good luck.

The whole problem may have started from improper threading or upper tension not operational or too loose. Make sure when you rethread that the upper tension is engaged when the presser foot is lowered and loose when the presser foot is raised. Also when you have the needle plate off that the bobbin case is in the proper position so that it can't turn too much only a very little. Just Enough so that the thread can make its way around without catching.

Bottom sitch skips and gathers and when I use reverse it gathers up. I have changed needle, thread and boobin, I have also cleaned and oiled boobin area.

Either your bobbin tension is wrong or, your needle isn't the right length for your machine. The bobbin tension is adjusted by the little screw on the side of the bobbin holder.
