I think I need a new bobbn case as the thread keeps binding up under the plate

Thread binds up under the plate and can't move the needle up or down. I have to remove the plate and remove a ball of thread that builds up over a projection behind the bobbin

Make sure your needle is threaded correctly and that the needle is not old or blunt.
make sure that the thread and needle size are compatible with the material you are using.Or check with manufacturer.

It could be the thread is hanging up and breaking the needle.

Check the thread spool for nicks - turn the spool so the thread is feeding from the bottom of the spool.

Watch the thread as the machine stitches, if the thread is pooling at the base of the spool, use a thread net on the spool.

Open the needle plate and remove the bobbin and bobbin case - clean out any lint or thread snips that may have accumulated there - do this often to help the machine work as it should.

I sounds as though the needle is not properly installed.

Replace with a new needle. Loosen the wing nut so the needle can be easily inserted into the holder as far as possible, with the flat side of the needle shaft facing the back of the machine.

Mega quilter binds thread under fabric


If you have to manually set the tension on your bobbin, your tension may be too loose or too tight. When my bobbin is full of thread the tension has to be stronger than when it is almost empty. So tight when it's full and loose when it's nearly empty. I hope this helps. If this doesn't work try using a air can to blow out the dust in your bobbin casing and make sure the bobbin doesn't have any burs. It needs to be wound smoothly. Also check for thread hangups in the bobbin casing area. Also you may want to completely re-thread your machine.

Need a manual for Singer sewing machine, model number 7442...need to know how to thread needle


You can download a manual for free from the Singer website, link is
http://www.singerco.com/uploads/download/465_7442_efs.pdf

just copy this link into your browser window and give it time to download as its a large pdf file. Once open on your screen, you can click the "clipboard" icon to save the file to somewhere on your PC. Then print it out and either bind up or put pages into a display book so its easy to flip through and stays with the machine.

Just remember to always thread up the top thread with the pressure foot up - this opens up the tension device so the thread can seat it correctly and is something often missed.

Also, use a new needle for each new sewing project, ie about 4-6 sewing hours change the needle and throw out the old one. A blunt needle is often the cause of bad stitching.

All sewing machines, whatever the make, will have similar key parts that are critical to threading up. These will be thread spool holder, the top thread tension device, thread take up lever, a couple of thread guides, the needle bar and needle. Thread in order from the spool down to the needle as per the threading diagram in your manual, ensuring you get the the thread into each thread guide fully, then thread the needle from front to back.

Place the wound bobbin into the bobbin case, it should rotate anticlockwise when you pull the thread tail. Now place the bobbin case into the machine using the latch, and it should lock into place when you let go the latch.

Now hold the top thread tail, wind the balance wheel (big one on the side of the machine) towards you to lower the needle through one stitch sequence so that the needle goes down then back up, now pull the top tail and the bobbin thread should be caught and pulled up to the top of the needle plate. Always hold both threads at the back of the needle plate as you start a new seam to ensure the threads don't get pulled down into the bobbin case/rotary hook area.

I am having a problem with my Janome Decor Excel 5018. It was working fine, until the bobbin thread won't gather with the top thread. And the top thread is binding up underneath the fabric. Kim


try a new needle

rethread the machine top & bobbin, that way you make sure the thread is not caught anywhere

make sure the bobbin is correctly inserted in the machine

clean under the needle plate & in the bobbin area for loose thread & lint

always keep a long thread tail of 3 to 5 inches long, & keep the tails pulled back behind the needle
before sewing

if none of these things help the problem,, then it may need to be serviced

Necci Lydia mk2 544. Something seems to be binding. does it need oiling. It only hums when using foot pedal.


try cleaning under the needle plate where the feed dogs are to get out any lint or loose threads
then clean the bobbin area for lint or loose threads

rethread the machine- top thread & bobbin--make sure to thread every thread guide

make sure the thread moves smoothly around the tension dial

also check the top tension setting -usually 3 or 4 is good

make sure the power cord is inserted correctly into the machine

it could also be the foot pedal itself may be going bad--it would have to be checked by a repair shop

always use the same thread on top & in bobbin area

put new needle in also

also some thread & needles are not compatable--try this

Cut 6-8 inch piece of thread of the spool you are going to use for your project
Take the needle you are going to use for the project
& insert the thread thru the eye of the needle
& lift one end of the thread to a 45 degree angle
& if the needle is the right size for the thread it will slide down the thread
But if the needle hangs on the thread you need one size larger needle for the thread

Try rethreading the machine, and make sure your bobbin is in the right way - check the manual.Also clean out under the needle plate- a build up of lint can cause all kinds of trouble.

Embroidery hoop gets stuck to the plate and needle breaks


This has happened to me as well. What I usually do is:-
* remove bobbin case and clean out any lint, also under the needle plate, then replace needle plate , bobbin case and the little front cover. replace the bobbin , checking that you have the thread going the correct way.
* replace the needle with a new one of the correct size for the weight of your fabric and the weight of your thread
*remove and rethread the top thread
* check that the stabilizer is of sufficient weight for the density of the design. (You may need to float an extra piece of stabilizer underneath the hoop)
* check also that it is bobbin-fill in your bobbin (it is easy to get it mixed up)
* when stitching out lace, sometimes it helps to hoop the solvy double.

Black bobbin case


If this is the machine I think it is the bobbin case is completely round as opposed to half round. If it is half round ignore the following.
Remove the presser foot and then the two screws which hold the needle plate. Lift off the needle plate and then lift out the old bobbin case. Clean all the lint out and then insert the bobbin case so that the less round part of it is to the back and the lip around the bobbin case is resting on the lip around the hook. Turn the hand wheel a few times to be sure it is working smoothly and not binding. Replace the Needle plate , bobbin and presser foot. Insert a new needle,thread the machine, Check your tension to be sure it is working correctly, turn the hand wheel again to be sure it is picking up the thread without binding and sew.

JUKI MO-634D trouble


Well, you might just need a good oiling. Make sure the machine is not threaded and there are no thread snarls where the loopers interact. It also pays to insert new needles and observe the loopers and needles interact. they should come withn .01-.5mm of touching eachother; there should be no hard positive contact between loopers and needles. So, if its tight to turn over by had, this is usually a cam or bushing that need oiling, or thread that got sucked into the machine and is binding the thing up. What I would do is remove the covers, slip the motor belt off, turn over by hand. If it frees up, the bind is in the motor, if its still tight, then id look for thread, and oil the machine with a light weight oil (sew mach oil, tri-flow... NOT 3in1 oil!). If you have a keen eye, you can wiggle the handwheel and try to observe what parts are moving slightly, and which are not. using that method you may be able to track the bind to a section of the machine or even a specific shaft/cam/component of the machine. Another common bind point in sergers is where the knives mate. Move the top knife to its idle (non cuttin) position and see if this relieves the bind.

Singer 3820 How I replace the bobbin case, it's loose and I can't sew!


remove the 2 screws in the needle plate. Lift off the plate.Take out the bobbin case and examine it for rough spots or nicks. If there are any it will be necessary to buff them with an emery stick or fine sandpaper. Once the rough spot has has been smoothed, buff it with some very fine steel wool. There must be no rough spots on this bobbin case.Clean all the lint from inside the hook area. Do not pull the wick from the center of the hook. Place the bobbin case in the hook area so that it sits flush and does not bind when the handwheel is turned.Reinstall the needle plate, thread the machine, insert the bobbin and turn the wheel to pick up the bobbin thread and see that it doesn't bind.Test sew

Take the needle plate off and turn the needle up and down by hand while watching to see if it is hitting anything. The hook timing could be off.
