How to fill the bobbin with thread


The bobbin is a little metal wheel that is usually housed under a plate where the upper needle darts down into. Slide the plate aside and fish the bobbin out. Put the bobbin up on the upper right hand side of the sewing machine and connect thread from the full spool of thread to the bobbin and then when you push the pedal down, (if you have arranged it right), your machine will automatically fill the bobbin with thread and automatically shut off when it is full. Then you have to leave a bit of thread hanging out when you put the full bobbin back down into its hiding space. Of course, you can always fill the bobbin by hand too. When you put it back in its housing, some thread has to be hanging out as the needle will drop down, grab it and the two threads (the top one from the needle, and the bottom one from the bobbin) work together.
Machines work differently but the is the main idea behind most of them. I hope that helps.

Bobbin winder stop before befor fully wound


Is the bobbin close to full in the middle but not that full above and below? You may need to watch the bobbin wind and give the thread a nudge so that it fills right across the bobbin core to avoid this happening. Most bobbin winders will click off before the bobbin is completely full as you don't want any thread actually touching the bobbin case when it is in position, just fill to about 80% for good tension and stitching.

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.

I was doing fine zigzag, ran out of bobbin thread did not change any thing and now the thread bunches on the bottom and the machine does not advance. Bobbin casing pop up also this is a 774 model


Hi there,

Well The most probable cause of the lower thread breaking is an improperly wound bobbin. Regardless of where you wind the bobbin, inside the machine, on the top of the hand wheel or on the front side near the hand wheel, the basic "bobbin" rules apply. 

** Always start with an empty bobbin. Never wind one color over another color.
** Don't wind the bobbin so full that it would be tight and hard to insert into the bobbin case. Most machines have an automatic "shut off" when the bobbin gets full, but if yours does not, be careful not to fill it too full.
** Wind the bobbin evenly across and in level layers.
** Never mix different sizes of thread in the bobbin and on the spool, unless you're doing sewing machine embroidery or some specialty type of sewing. Using different weights of thread on the spool and in the bobbin for general sewing will cause ragged stitches as well as other stitching problems.
So clean all the threads and do it work from start.........
Please reply ......
Thanks

Bobbin stops before it is full. Is there and


There ought to be a stopper arm that touches the thread and stops the winding.....a small screw nearby ought to be the way to adjust the depth of the arm....use an empty bobbin...loosen the screw, move the arm toward the edge of the bobbin, then re-tighten.
DO NOT UNDO completely or bits may fall into the machine

Automatic bobbin winder does not stop when bobbin is full


Simply loosen the screw on the bobbin winder stop, no more than 1 full turn or you will drop the backing nut will fall down into your machine, move the bobbin winder stop slightly to the left then tighten the screw and see if that works. you may have to repeat this step several times until you find the right spot to stop the bobbin at the correct point.

Husqvarna viking, interlude 435...unable to solve tension problem


Sounds like the tension unit is at fault. First check the bobbin tension by removing the bobbin case. Use a half-full to 3/4 full bobbin. Be sure it is threaded through the bobbin case with thread hanging straight down with tension spring on top. Tie the stitch plate to the end of the thread. If the thread pulls the bobbin out, the bobbin tension is too loose. If it does not move when "jiggling" the bobbin, it is too tight (which is not likely based on your description). Small screw (through an open hole) on the side of the bobbin case adjusts the tension of the bobbin case. Left for loose and Right for tighter. Otherwise, contact local authorized Husqvarna Viking dealer for their assistance. You can find the closest dealer at the Husqvarna Viking website - http://www.husqvarnaviking.com/us Good luck.

Singer 2662 winds bobbin only half full.


there is an adjustment on the bobbin winder. Just bend the little spring flap that rides inside the bobbin while winding. Bend it up a little. The flap being pushed up is what releases the shut off

Bobbin does not fill completely


Machines that stop the bobbin winder automatically when the bobbin is full have a mechanism that detects how much thread is accumulating in the bobbin while it is winding, then stops the winder when the bobbin is full. It is likely that the bobbin winding mechanism needs to be adjusted by a mechanic. 
On the other hand, if the thread winds evenly, and stops winding when the bobbin is about 3/4's full each time, you probably don't need to worry about it if all else is good (even tension, consistent stitch quality, and so on). 
If you'd like me to post some general troubleshooting tips, let me know.
Good luck

Is it the correct size bobbin?
If you have spare bobbins do they all make a noise?
