Question about Baby Lock BL1556

Open Question

I can't get the upper thread to pull up the lower thread.

The machine was working fine, but i was having some tension sewing some denim. I decided to change the needle, and now i can't get the lower thread up. The upper needle just goes up and down, but the thread isn't catching and going all the way around the bobbin mechanism....

SOURCE: Not picking up the Bobbin thread

I cleaned the machine good with canned air, oiled it. I took out the bobbin case and cleaned it good also. I then noticed the tension screw on the bobbin case was loose, tightened it and the problem was fixed.

Sounds like you have to take off the throat plate and clean out threads under it.  Sometime they ball up and prevent the needle from going down and catching the bobbin thread. You can't see themuntil you take off the plate.  Follow the directions.  It is easy.

Check the easy stuff first:
Make sure the needle is inserted in the machine properly- a good rule of thumb is the flat side of the needle should go to the opposite side of the last thread guide. Also make sure the machine is threaded correctly.

the needle is in correctly with the flat side to the rear of the machine, make sure to thread the upper and lower portions of the machine correctly.

the needle is in the machine correctly- all the way up into the needle bar, make sure that it is threaded correctly, etc. If this all checks out ok, take the bobbin case out of the machine. There are two ears on either side of the bobbin case- turn the left one to the left and the right one to the right. Remove the silver ring, and inspect the piece of metal that the ring came off of (looks like a circle with the top cut off). You have to locate the hook which is the piece that looks like a half moon inside the big round metal piece. Locate the tip of it, turn the handwheel toward you until the needle is in the lowest position, at this point the tip of the hook should be flush with top of the left side of the cut off circle. If this is not so, your machine needs to be re-timed. If that is the case.

Probably a little heavy duty for a domestic machine - most don't like thread through the bobbin tension device any heavier than 50 grade.

Some tension devices have a hole that you can use to bypass the tension spring (Elna is one) which allows thread like perle cotton to be used in the bobbin. But you still can't put it through the needle (just on the underside for decorative sewing effects) .

In the past I've needed to sew vinyl tractor seats where I was stitching the vinyl to a 1/4" thick foam and after trying everything (roller foot, leather needle) on the domestic machine, I bought a Singer 20U industrial machine with 1 1/2 hp motor in a table in order to seam this weight of textile. Different system needle used and the bobbin could handle heavier weight thread.

Probably not the response you wanted though.

How do you adjust the bobbin tension?

Factory standard tension for upper thread is the midway point between the high and low number. However, that tension dial is meant to be used for tweaking tension. Generally, tweaking is required whenever the type of fabric, needle, or thread are changed, ie thicker fabric like denim should have a different upper tension setting than fine chiffon. To be successful with tension settings, one must become comfortable adjusting the upper tension.

NOTE: Accurate tension is achieved when the upper thread and bobbin thread meet in the middle of the fabric.

Lower thread too loose

Big loops on the bottom of the fabric is NOT the lower thread. First make sure that your upper thread is correctly threaded with the presser foot in the UP position. Do a test seem. If you still have loops tighten the UPPER tension knob. Do a test seem.

If after several upper tension changes do nothing. Remove the upper thread and take some rather rough sturdy fabric like light weight denim and "floss" where the tension discs are then rethread... and try again.

Hello, I have a Shark euro-pro sewing machine. I am sewing denim on denim using singer needles that were suggested for denim. The numbers on the package are 2020 110/18 808 R 130/705H 05 un I...

The size of needle is fine for sewing on denim so unless the needle is bent (and even so) I doubt that is the problem. Breaking upper thread typically has more to do with the threading, ie wrapped around some place along the way or misthreaded somehow, of even if you somehow got knots or that it has somehow got thread around the spindle for the spool. So first recheck the threading. Best to do by simply totally unthreading it, looking closely at the spool and winding and then rethreading it again. Make sure your upper tension hasn't been accidentally tightened too.

Next check the bobbin and bobbin thread. First pull on the thread. Is it pulling real tightly or does it flow out readily? Take the bobbin out and look at it. Check the tension also. Is it too tight? That too can cause the upper thread to break.

Is the needle penitrating the material smoothly? Again examine the needle closely to see if it's developed a burr. Better yet just swap the needle with a new needle and try it.

The majority of the time it is one of these things that will cause the top thread to break.

When I start sewing the back of thread is all overlap and tangled what can I do?

A more detailed description would be helpful, but my guess is that you have lost all of your upper tension.
Unthread the machine. Raise the presser foot. Turn the handwheel until the take-up lever is at it's highest position. Set the upper tension dial/knob to 5. Thread the machine.
With the presser foot up, the upper thread should pull through easily and then grab when the presser foot is lowered.
Test sew.
The upper tension pulls the stitches up and the lower tension pulls the stitches down. When they pull properly, the stitch is even.

My bobbin stitch is loose. I have tried adjusting tension and have changed the needle.

A. To correct loose stitches, try the following: (1) Balance the thread tension. If the stitches are loose on top of the fabric, decrease the tension to the next lower number. If they are loose on the underside set the tension to the next higher number. (2) Make sure the needle/upper thread follows the threading path. (3) Check to see that the bobbin case is threaded properly. (4) Use a different size needle. For fine fabrics, use a smaller needle (size 9, 11); medium-weight fabrics require a size 14 or 16. And use a size 18 or "Denim" needle for heavy corduroy or denim.

Singer sewing machine 6215c trouble w/stitching - top looks fine, underside all loops of thread

The problem is actually with the upper thread not having enough tension on it. Check your upper tension setting,,,it should be set about mid range of its adjustment (4,5 or 6). To see if the tension is functioning correctly thread the machine and raise the presser foot to its up position and pull thread thru the needle. It should pull easily, lower the presser foot down to the fabric and now the thread should become harder to pull. If there is no change in the pull,then either the thread is not in the tension correctly ot the tension is not working,

How to Thread Juki MO-134 Serger from watching lady at Lyles. Turn upper blade up. Push in first then turn up.It makes threading easier. Blue Thread upper looper first. Pull thread through tension knob. Don'tjust lay it there. (She thought that is what I must have done) Orange Thread lower looper next. Pull thread through tension knob as inthreading upper looper. Adjust lower looper so it is right nextto upper looper so that their points are almost together and directly belowsewing needles. Lower looper will be in front of upper looper (I believe). With tread from upper looper pulledback, slightly lift lower looper above upper looper and thread. I think this isright. Pull thread back with other thread. Tension is the key. Remember that. Yellow: Thread left needle first.Remember tension. Pull thread through curled wire on left side of needle arm. Green: Thread right needle. Rememberabout tension. Pull thread through curled wire on right side of needle arm. b> Note: Before sewing turn the wheel tomake sure the stitches are going together correctly.

Under side of fabric.... the thread is a mess

Remove the thread from the upper portion of the machine.

Place the presser foot in the up position.

Turn the handwheel so that the take-up lever is in the highest position.

Ensure that the upper tension dial/knob is set to 5.

Thread the machine all the way and through the needle.

With the presser foot still up, hold the thread from behind the needle and pull about a foot of thread through. It should pull through with very little resistance.

Now lower the presser foot, pull the thread and you should feel great resistance.

If so, now try to sew.

If not, there is a problem with the upper tensioner.

Sears Kenmore sewing machine model number 15358 tension issues

#14 needle is way big for cotton napkin scrap. a #10 is good for most lightweight fabric. #14 is for sewing denim or levis, like that.

the tension problems on almost all machines regardless of price usually fall on the upper tension. the lower bobbin tension is factory set and it's rare you should ever need to mess with it.

if you have a drop in bobbin (top loading), tighten the adjustment screw all the way and then back it off 1/4 turn. if your machine uses a shuttle bobbin, tighten the adjustment screw all the way and then back it off in 1/4-turn increments until you can hold it in the air like a yo-yo and cause to bobbin case to fall slightly dipping your hand.

A dull needle and stitch length will also mess up your stitch. The idea is to narrow the problem down to one thing and one thing only -- UPPER THREAD TENSION.

So, if you have the right size needle for the job, with the right thread, and if your stitch length selection is correct (usually between 2 and 3 or 8-to-10 stitches per inch, the problem should be with your upper thread tension.

An easy way to fix this then is to remember: Loops on top, upper tension drop. Loops below, upper tension grow. If you get loops on top of your work, lower (drop) your upper thread tension to a lower number. If you get loops on the bottom, raise the upper thread tension.

Different stitches on the same machine will require different upper thread tension settings. Don't be afraid of it. Just remember the pneumonic: loops on top, tension drop, loops below, tension grow -- referring to upper thread tension.

have fun :)
