There are several factors to be consider if the machine was not threading kindly check the upper thread tension should be complied to the fabrics,check also the tension the bobbins thread
theres small adjusting screw on the bobbins,the thread that come out to the bobbins should be on the counter clockwise rotation,set the acquired stitch adjustment,check the needle alignment and then manually turn the handwheel if the needle thread hook up the bobbins thread also it would be helpful if the feed dogs is clean and free from dust and chips fabrics and chips thread.

What is normal tension settings on a kenmore model 158.12112


The tension depends on what you are sewing but usually a 4 -5. Also make sure thread and needle are the correct size for the materials you are sewing. and make sure needle and bobbin are threaded correctly and that needle is not, blunt or bent. :)

Fashion Mate 248. The top stitch is fine but will gather too much under the material. Wraps around the bobbin holder and tangle up into the bobbin thread. Does anybody know whats going on?


That is what is referred to as bird nesting or thread nesting. It usually results from mis-threading, the thread not being fully seated in the tension disk, or the tension set too loose. (I have a machine that does this frequently because the thread "jumps" out of the take up lever when sewing fast--instant thread mess.)

Remove the thread from the machine. ALWAYS RAISE the presser foot and rethread from the beginning. Make sure the thread path is correct. Set the upper tension to the midway point between high & low number. (You will probably need to tweak the upper tension because every machine differs over time, but the midway point is the factory standard setting.)

While you are at it, check to make sure the bobbin is loaded and threaded correctly in the bobbin case.

If you continue to have issues, you may need to take it for service.

What am I doing wrong when the stitching on top of the material is ok and straight and the backside is knotting?


wrong bobbin tension , but amazingly its actually easier to adjust the top threads tension to compensate for it , use your tension knob to slowly adjust , try an inch , slowly adjust try an inch , and so on to get a top and bottom thread tension to match , this will need to be adjusted for each major change in fabric (aka , knits to woven )

Have a Singer 11910000A and the bobber thread bunches up and makes a mess in the feet when sewing


Is it really the bobbin thread that is globbing? Check closely. Usually it is the upper thread accumulating under the fabric.

If it is in fact the bobbin thread, then the bobbin case is not threaded correctly, the bobbin case tension needs adjustment, or it is broken and needs replacement. There are web sites and YouTube videos that show how to adjust the bobbin case tension.

QUICK FIXES: Remove all the thread from the machine. Clean the area around the feed dogs and bobbin area. Oil as instructed in the owner's manual using ONLY fresh, good quality sewing machine oil (only 1-2 drops each spot). Install a brand new needle insuring it is installed correctly. Avoid using fuzzy, old, or bargain bin thread. Rethread: Be sure you raise the presser foot BEFORE threading the upper thread so it will seat properly in the tension disk--and check to make sure you are threading the machine correctly. Check that the upper tension is set properly (the factory standard is usually the halfway point between the high & low number on the selection). Test on a scrap of the fabric you wish to sew. Adjust the upper tension--either tighten to pull the upper thread toward the top of the fabric, or loosen to pull more upper thread down.

Here are some web sites that may help.

Feeder not moving


knotted up thread under the material indicates that the needle thread tension is incorrect ( needs tightening)
once you have that correct the material, will feed normally
use scrap when adjusting and the correct tension is when the top and bottom threads meet at the join ( middle -center )of the materials being sewn

It wont stitch tee/shirt material it misses stitchs


If machine misses stitches consistently, it can be several things.
Needle not installed correctly, not threaded correctly, Bobbin case not installed correctly, make sure the bobbin itself is inserted correctly and spinning in the correct direction.
Finally, machine may need service the timing is off. All actions of a sewing machine are carefully "timed" to form a stitch while sewing. Sewing things that were too heavy for the machine or you hit the bobbin case while sewing can knock the machine out of adjustment.
Let a professional do the maintenance on your machine. Some may opt to show you how to do more in depth maintenance yourself at home.
Cheers,

Make sure your machine is set to feed material. There may be a switch or knob somewhere on your machine to lower the "feed dogs" (the little metal teeth that pull the material through the machine). If they are down, the material won't feed so the machine will sew in place. More likely, since its knotting on the bottom, your machine is probably not threaded correctly. Rethread the machine, and try again.
Yes, the thread on the bottom IS the needle thread.
