SOURCE: Bottom thread will not catch

Unplug the machine and remove the needle plate so that the bobbin case if fully exposed. Lift out the bobbin case and the cup that it sets in will be visible. Locate the "hook" on this cup. It is a finger with a sharp point at the upper edge of the cup. The hook is what grabs the thread from the needle while sewing.

  • Thread the needle.
  • Turn the handwheel by hand.
  • Watch the hook as it approaches the needle from right to left.
If the hook passes by the needle AFTER the eye of the needle is above it, you timing has slipped and the machine must be taken in for repair.
If the hook catches the thread from the needle, put everything back together and try threading again.

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: bobbin thread won't catch with needle thread

check that the needle is in the right way round i.e. with cut out on the needle facing into the machine. if this is fine then check that as the needle comes back up from the lowest point that it goes to, that the point on the bobbin case passes just above the hole in the needle, i.e. in the middle of the cut out.(if not it needs re timing) if threaded a small loop should appear at this point for the bottom bobbin to catch if not slacken the top thread and try again.

Why does my thread keep bunching up?


That is called "thread nesting," and several things can cause it. The upper thread enters the bobbin area during sewing, catches the bobbin thread, and as the needle goes up, pulls the stitch tight. Something is catching the upper thread as it goes around. The most common reasons are the bobbin or bobbin case (or both) is improperly inserted; the bobbin is warped (roll it down a flat surface--if it wobbles, it's warped), either the case or the bobbin is not seated evenly, there is a rough spot on the bobbin case that is catching the thread, or your bobbin is loosely/badly wound. You need to rule out the possibilities step by step until you find the cause. First, review your threading procedures from start to finish, using your user's manual. Then, without fabric, turn the hand wheel by hand (ALWAYS towards you) to see if you can see it start to catch. The top thread should rotate smoothly in the bobbin area. You should be able to pin-point the cause that way.

Upper thread is not catching bobbin thread


Carmen, seem that you have carried out the necessary rectification, but could it be your rotary hook tip blunt/broken, if not most probably it needs needle/hook timing adjustment. And this will require your sewing machine technician to do it.

I have a brother ls-2125 sewing machine. the upper thread is not catching the bobbin thread properly. help please


  1. Tension
    • Your sewing machine tension controls the rate at which the thread is fed through either the upper section of your machine or through the bobbin case. If your upper or bobbin threads aren't threading properly, sometimes adjusting the tension will correct this problem.
    Timing
    • Your sewing machine works by passing the upper thread through the needle of the sewing machine at precisely the same time the bobbin brings its thread to its uppermost position. If either the needle or the bobbin thread reach these positions too soon or too late, the threads won't interact and create the knots that make the seam. You can throw off your timing by sewing too many layers of fabric or hitting a pin with your needle. See you sewing machine repair facility to correct any timing issues.
    Thread
    • Thread can get snagged or caught in the upper section of your machine or on lint pieces in the lower bobbin section. If your threads aren't catching properly, you may be able to fix it by unthreading and rethreading both your upper thread and bobbin threads.

The bobbin thread is not catching. I have rethreaded the entire machine multiple times, tried different bobbins, etc. However, the needle and thread are not catching the bobbin thread. The bobbin thread is...


try a new needle
make sure the bobbin is not warped
make sure the bobbin case area is free of lint or loose thread
make sure you hold the upper thread tail while it's going down to pick up the bobbin thread
make sure there is a 2 to 4 in tail for the upper thread to grab

Upper thread will not catch bobbin thread


Your machine is out of time. It would be best to have a tech adjust the timing.

Bobbin thread won't catch


I've just had this exact problem with my model 2037. The problem, according to 3 shops I've taken mine to, is that the shuttle hook (the metal piece that the bobbin sits in) is broken and needs replaced. Problem is, the piece is next to impossible to find.
