If you can see if more than just a tiny bit, you need to adjust your tension on top. It should be even. The best way to test it is to use 2 different color threads and then a different color fabric. Stitch a straight line, then look to see what color you see on each side.
You thread a needle with the thread you want to pull through, pass the needle into the material slightly within the margins of the pattern and pull the thread through. You don't really have to pull the top thread through to tie off because the stitch density is high enough to lock the thread, you can clip close. If you feel the need, unpick a few stitches (don't rip them, unravel the top and bobbin threads) until you have enough length to work with, pull the top thread through the fabric with the bobbin thread ad tie them together. When you change top thread, lay a short tail of the previous color and the new thread across the next pattern section and the thread will be locked. Same idea when you change the bobbin thread
For the bobbin wheel. This is a small thread spool that is located below the sewing table. The needle draws out the bobbin and along with the top spool of thread, sews the garment.
The winder allows the machine to transfer thread from a spool onto the bobbin, which provides the underside, connecting, stitches. It does a better and more even job of it that winding the thread by hand.
To wind the bobbin you thread the machine except for the hook above the needle and the needle itself and pull the thread over the notch at the top on the front. Start the thread on the bobbin just till it stays and then place it on the little post on the right side by the wheel and pull down the small lever just above the post and then press on the pedal and wind till the bobbin is full. I still haven't figured out how to thread the bobbin yet but it shouldn't be to hard.
A bobbin winder is the part of a sewing machine that takes the thread from a spool of thread and winds it on the bobbin. The sewing machine bobbin is a mini-spool of thread, made of plastic or metal, that holds the thread that will be on the underneath portion of your fabric when you sew. The top thread comes from the spool of thread and the thread on the bottom side of your fabric comes from the bobbin. Instead of winding the thread on the bobbin by hand, long and tedious, the machine will wind it for you if you load it up correctly. Check your owner's manual for instructions. If you don't have a manual, do a google search for it by entering the name of your machine branch and the model # and it will probably find one. Also, any experienced sewer can show you how.
I'm assuming you're talking about winding a bobbin on a sewing machine? If so, there is a post similar to the one for thread (near it) that you put the empty bobbin on. Then you put your spool of thread where it goes on the machine. You wind your thread from the spool of thread to the bobbin (there's usually a little chart on your machine, but if not, the thread goes through a hook or two and then you wind it about 4 times around the bobbin (clockwise). In newer machines you then push the bobbin toward a holder type thing that is near it. This disengages the needle from going up and down and lets the machine wind the thread as you push the pedal. On older machines, you have to turn the handle of the machine toward you and it disengages the needle, allowing the bobbin to be filled when you press the pedal. Hope this helps! You could probably google your sewing machine name and how to thread a bobbin and maybe get a diagram.
A sewing bobbin is a small spool of thread that goes underneath the needle and sewing platform. It provides the lower thread for the sewing machine. Different models of machines use different bobbins, but most machines require you to create the bobbin yourself.If you'd like to see a picture of a typical sewing machine bobbin, visit the "related link" below.If you look at a diagram of the way a sewing machine works, you can see that when the needle goes down to the bobbin, the bobbin thread is pushed around the upper thread, and that is how the two pieces of fabric are joined together.The upper thread goes along the top of the seam, and the bobbin thread goes along the bottom of the seam.
I'm not exactly sure what you are asking, but if it is "WHAT IS a sewing machine bobbin?" then I can help. The sewing machine bobbin is the round "wheel" like part that holds the thread under the sewing needle. In the older machines it was metal, and in the newer machines it is mainly plastic. Mostly, these bobbins are not interchangeable from one machine to the next. Each sewing machine brand requires its' own specific bobbin. Without the bobbin (with thread on it!) a machine is unable to sew.
such as in a sewing machine? Your sewing machine should have a button on it. it should have to 2-3 spindles at the top. Using your spindle of thread, thread through the machine and wrap thread around bobbin, replace bobbin back where it was and push your foot pedal, if this dont work find the brand name and write to the company and request a handbook. You can find the company from searching the net.
The tension control on a sewing machine determines how tight or loose the thread in each individual stitch is. The top and bobbin thread tension is like a tug-of-war. If each side is pulling equally, you have perfect tension. Imperfect tension is evidenced by thread loops on the bottom if the top tension is too loose and the same on top if the bobbin tension is too loose.
The needle does not draw up the bobbin thread. In actuality, there are two "needles" used. The one you see, that moves up and down into the fabric, and another, underneath, which pushes the bobbin thread through a "loop" in the thread from the top needle. When the top needle begins to raise up, it pulls the threads tight. If your problem is that the top needle goes through the fabric, but does not "sew" it, first check to make sure the bobbin has thread in it. If it does, then check to make sure the machine is threaded properly. If it is, then the problem sounds like the bottom "needle" is not meeting the top needle at the precise time to push the bobbin thread through the loop. This is called being "out of timing". Just like in a car, all the cylinders have to be in the right place at the right time to make the engine run. Same thing in a sewing machine. The needles and the thread have to meet in the right place at the right time to work properly. If you are out of timing, unless you know alot about your machine, it will require a repairman to remedy this situation.
It relates to the orientation of the hook (the part under the bed that catches the top thread to create the lock stitch) to the needle. Horizontal machines often have a 'fixed' bobbin case that the user doesn't remove, and utilize a drop-in type of bobbin, whereas vertical machines have removable bobbin cases that the user must insert the bobbin into, then insert the filled bobbin case into the machine. Horizontal bobbins usually hold a lot more thread and make it easier to replace the bobbin without having to remove the work, therefore you will commonly find this type in industrial applications.
