SOURCE: bobbin thread not catching

Whenever you see loops on the underside of the fabric something is snagging the thread. the biggest culprit is burrs on the hook. the hook is what goes round and around the bobbin. The reason for burrs on the tip of the hook areseveral

ONE ...is by helping the fabric through as the machine is doing the sewing which directs the needle too close to the hook thus scarring the smooth surface of the hook and potentially breaking it off and the needle too. You must allow the machine do it on its own and only guide the material.

TWO...Sometimes if you are sewing s-t-r-e-t-c-h-y double knit material the material calls for a ball point needle. I have gotten good results with the Singer brand YELLOW BAND needle.

Three ... The hook could have gotten out of timing. What this means is that the hook is not meeting the needle on the top edge of the eye of the needle. You yourself can check this out by removing the bobbin (or shuttle, cassette). Install the needle flat side to flat side of the mounting rod and all the way up. By slowly turning the handwheel on the right slowly and watching that the eye of the needle is just below the hook on the upward swing of the needle and that they both meet dead center. This when you need to take it in to a repairman. FrankIy I don't like to advise this because of unscruppulous practices. My boss used to call me a virgin Mary because I wouldn't ripp-off the customers. Anyway at this time you can also check the condition of the hook carefully looking for nicks and scratches on or around the tip of the hook. If there is damage present you can file this down with a very fine emory board or by using a strip of 400 to 600 grit sandpaper as if your were buffing a shoe. If the hook is removeable by unsnapping the snaps on either side its easier to buff. Anything courser may contibute to the problem. If the paper won't remove the damage you may need a whole new hook. If its not removeable you will have to take it in to have it installed.They have to time it properly.

Four...The two disk that you mentioned also has a spring. That sping is there to pull up those loops. If the disks are full of lint from the thread going through. the clups of lint won't allow the discs to apply tension on the thread and thereby having tightened the tension so much that that spring is not working properly.You can clean the discs by raising the foot which opens the discs. With a long narrow pick pull out all that lint without scatching the discs. Check closely that the the thread goes across the top of the machine down through the discs pull up snug so the spring engages,through the take up arm,in the two thead guides, then into the needle front to back or right to left, if it is a side loading bobbin. Now the tension will work properly!

TESTING : Move the TENSION dial to mid point of the dial usually 5. This is your starting point.
With two layers of fabric ( not stretchy) and with a regular needle, set stitch length at about 12 per inch on the dial. Now sew about six inches. Raise the fabric and look at the results. Do minor adjustments necessary on your tension dial up 6...7.. if loose on the bottom 4...3..2 if loose on top.
If you did all the steps above those are the steps a repairman performs and charges $75 except me I used to charge $10 .

Brother machines are good quality it is those hidden gremlins that make a fun hobby frustrating when you don't have someone to turn to without having to shell out cash! Its been a pleasure!

SOURCE: Singer Touch & Sew won't loop bobbin thread

I believe you have a broken gear. These are difficult to repair on your own.

SOURCE: Needle thread looping underneath, threads not interlocking at all

If the machine is now threaded, lift the presser foot.

Now, pull about 10" of thread through the needle.

The next time you thread the machine, lift the presser foot first.

When the presser foot is up, the tension control opens and allows the thread to "seat" into the control, then when the foot is down the control closes to the indicated setting.

When threading the machine with the foot is down, thread does not enter the tension control and when you start to sew, there is no tension on the thread.

No tension = loosey, goosey, loopy stitches underneath.

Because the lack of tension on the top thread, the bobbin thread cannot lock a proper stitch.

SOURCE: how do i fix the timing on my pe770

Timing this machine is not so easy but if U want to try... Remove the left bottom panel (one central screw), and look under. U will see by the rear the vertical gear making the hook turn. At the bottom of this gear, U will see a small allen. Slack this allen screw, LEAVE A TENSION ON THE ALLEN SCREW: eitherway the hook will not follow the gear when U bring back the assembly to retight the allen screw.
U can now turn the hook on the gear, allowing to change the timming.

Send the needle completely down and when it come up, the point of the hook has to arrive at 2.5mm. on the top of the hole on the needle.

A TRICK : It might be easier to slighly change the position of the needle in the needle bar. Check the timing and try to correct it but lowering a little bit the needle before tightening the scew, or cut a little bit top part of the needle with a grinder.

PE770 thread seems to be getting hung up on metal hook behind bobbin assembly


If thread is getting wrapped behind the bobbin assembly, most likely your machine needs service as thread behind the bobbin assembly should not be a normal occurrence.

My Brother PE770 was sewing fine and all of a sudden started looping on the upper embroidery. I have cleaned the bobbin case, rethreaded etc.


The bobbin case sounds like it became loose for some reason. You need to fix this. Somehow the thread isn't under the tension spring. Check that bobbin! The only other reason is the top tension became too high. When you are threading the top do it with the pressure foot up. As you are threading the top apply little tugs to see if there are snags. This will tell you if you are having problems on top.

My brother pe770 is allowing bobbin thread to show on top sporadically which makes the stitching look like it is speckled with white. I have adjusted tension..cleaned and changed everything.


Shelia,

when sewing these parts of the design, (small stitches? ) load your bobbin with the same top thread. Just match the top thread color, and done! No more white bobbin thread in the topside of your designs.

1. thread machine correctly.
2. make sure the bobbin is installed spinning the right way in the bobbin case.
3. put the tension knob back to middle (if this is possible numbered tension knob)

Handwheel is locked down


Several things to check. Did the needle break and jam in the bottom? Is the needle bent or did it jam in the bobbin area? I had a 'knot' of thread build up on the bottom and it hooked itself into the metal clip on the bobbin so that the needle couldn't raise. If thread jams in the bottom cut the threads until you can free the hoop and material. Check the bobbin for pieces of thread and fuzz. Check to see if the bobbin case or the throat plate is scratched or bent. If you are stitching Free Standing Lace on this machine or a piece with over 20,000 stitches I recommend starting with a new full bobbin and a new needle. As you get toward the bottom of the bobbin, thread seems to have a high likelihood of tangling or looping and will cause a jam which means the handwheel locks.

Brother pe770 bobbin thread is showing on top of fabric.


First check threading. If it is done properly, then it's probably because it is dirty between the lower tension blade and the bobbin case body. Remove this blade, clean, reassemble and it shoud work.

I have a brother pe 770 and the bobbin will not catch the thread. The thread will wrapped and tangled up around the bobbin case and bobbin, but will not catch the bobbin at all. I chcked the needle, it is...


You need to sew the first stitch slowly. Lower the needle by hand and take up carefully. Pull the needle thread up and the bobbin thread should be caught in the formed loop and come with it. Pull them both to the back of the machine and sew.

Check your threading.
Berhaps your thread is not between the discs.
