Check your tension disks, with your presser foot up, and the tension dial on zero. Sometimes a piece of cotton breaks off between the tension disks and then prevents the disks to work properly. Also make sure when you thread the machine, the thread does go through the disks and over the take up lever. After you threaded the machine, before putting the thread through the eye of the needle, lower the presser foot and while pulling on the thread with your left hand, increase the tension with your right hand. Do it slowly and you should feel in difference in tension. If this is the case, your machine should work fine. Good Luck!

I'm having trouble properly threading my Elna 1010. Could you please help? The bobbin thread keeps bunching up and breaking


bunching of thread under the material is an indication of insufficient tension of the needle thread
increase the needle tension until the threads meet at the center of the materialbeing sewn

Keeping the thread in needle when you begin to sew


after threading the needle pull about 6" of thread out the back under the press foot
that way the thread is jammed under the foot and is held in place for the next thread
bobbin thread should also be out the back
when you have finished sewing then lift the foot and move the material sewed about 6"" away from the foot before cutting the threads

I suspect that the bobbin thread you are talking about is in fact the top thread that has been pulled under the material, make sure that the top thread is pulled into the tention discs firmly and that there is no fuzz in with the thread, also make sure the top thread is properly threaded and is actually in the take up bar .

How do you adjust the bobbin


Hello

Set the tension on the sewing machine for the weight of the material you want to sew. The tension setting shows in the stitch on the material. Use the chart on the machine that matches types of stitches with suggested material tensions. An example of this is, the stitch to sew jean material is different than the stitch to sew silk.

Take the bobbin and wind the thread around it. Make sure the bobbin is empty and don't fill it too full of thread. A bobbin filled too full won't stay tightly spun.

Thread the string evenly on the bobbin. Move the thread back and forth evenly and in layers that are level. Many Singer sewing machines have a bobbin winder on the top of the sewing machine, and the consistency of how it threads can save you frustration later.

Find the hole on the bobbin that is located near the inside spindle of the bobbin. Take the thread sitting on the sewing machines spool and insert the thread in the hole from inside the bobbin to the outside. Set the threaded bobbin on the spool designated for spinning on the top of the sewing machine for some Singers.

Turn the side drive wheel slowly until the threaded bobbin has a layer or two of thread on it. Push down on the drive peddle and fill the bobbin, but don't thread it to the very edge. If the bobbin is too full the thread will release erratically. Cut the thread from the spool.

Drop the bobbin into the bobbin case under the area where the needle sews the material. Close the case and turn by hand the side wheel drive until the bobbin threads into the sewing machine. You can tell when the bobbin is threaded by the tiny piece of thread that juts out of the bobbin case where the needle goes up and down.

Grab the thread with your fingers and pull it out approximately 4 inches. Your bobbin is now spun and threaded.

Needle only moves a little and then beeps saying needle up when the peddle is pushed. Machine will not run.

The bobbin thread keeps getting matted up and pulling the material in the bottom... I'm using a heavier thread, and have tried several differant kinds of material to see if that was the problem...


Be sure to use the correct thread, advised in your manual and that your bobbin and top threads are not too different or else you will have problems. If, you are using a real thin material, try putting tissue paper under your fabric so that it won't get caught. in the needle hole. Usually matting under the fabric is caused by incorrect threading but I am suspecting your thread itself. If, you don't have a manual, go brother-usa.com and download one for free.

The bobbin thread is too loose and bundles up when I go to more than 3 layers . I need to sometimes go through a thick plastic vinyl window material, which with some seams will make 4 or 5 layers through...


--Some times you may have to use a neelde with a larger eye so that the thread will flow though the needle easier,
-Sometimes the clearance on the bobbin case stop has to be adjusted to allow for thicker thread,
-Be abundantly sure the top thread is through the discs on the top tension and not behind the tension devise, then increase the tension to a tighter position. if there are numbers on the tension, og to 5-8 so tyhat the thread will pull up into the fabric and not form loops under the fabric
-What type of thread are you using, possibly try a thinner thread
-check the bobbin as it spins in the bobbin case and after you have put the thread under the tension spring on the bobbin case, be sure the thread will pull out of the bobbin case relatively easily if not loosen the screw on the bobbin case ( righty-tighty/ lefty-loosey)
if all this fails you had better take it to an industrial sewing machine technician

I am trying to sew and the thread keeps clumping up at the bottom.


Hello,
Try these solutions.

* Re-thread your machine as it may be threaded incorrectly.

* Raise your feed dogs If your machine has this feature.

* When you start to sew a seam, hold the upper and bobbin thread tails back and out of the way as you sew your first couple of stitches. This will keep them from getting caught in your machine.

I hope this helps.
