Question about Singer 5050 Mechanical Sewing Machine

2 Answers

Sewing machine works fine as I sew, then for some reason thread will become very loose on bottom of fabric, and then machine freezes and it is hard to turn needle, or pull fabric away from bobbin. I end up cutting bobbin thread, and there will be a clump of thread stuck on needle plate and inside bobbin. I clean that off, and can sew again, but this keeps happen during sewing at diffent times. I notice that it sounds like bobbin is rattling around inside of case. My Singer sewing machine is from 1980's but the bobbin case looks okay, and I am using new bobbins that are suppose to fit, could this mean I need a new bobbin case? Thanks for any help! Kathy

Check and reset your needle and make sure the flat side.Is facing correctly then I suggest you rethread the upper thread being careful to each step correctly. Then pull out your bobbin and reseat making sure the bobbin unwinds the correct direction (counter clockwise for a xl 5130) when you pull the bobbin thread. Also make sure you have the right needle and thread size for your fabric.

Straight stitch. Top is fine loose on bottomadjusting top tension does not help how to adjust bottom tension?


Usually, if there are loose threads under the fabric, it is the top thread that is too loose. Check your sewing sample closely--you can even test with two different color threads to help distinguish which thread is which. Loose top thread will generally be pulled DOWN and show under the fabric. Loose bobbin thread will be pulled UP and show on the top of the fabric. The ideal tension is when both threads MEET in the middle of the fabric.

First, remove the thread from the machine. Install a brand new needle. Always Raise the Presser Foot and thread the upper thread, making certain the thread path is correct.

Check that the bobbin thread is threaded correctly and turning the proper direction in the bobbin case.

Set the upper tension to the midway point and sew a retest. A tweaking of upper tension may be necessary to get it where it should be. Generally, upper tension should make the majority of adjustments needed for tension correction. Bobbin tension is one of the last tension adjustments to make as it is very sensitive and can go awry very quickly.

If, in fact, the bobbin tension is off, the tension skrew on the bobbin case is where the adjustment is made. Before making any bobbin tension adjustments, mark where the skrew slot is located on the bobbin case with a permanent marker. This will allow you to reverse your changes if necessary. Be CAREFUL as TINY changes make HUGE differences in tension. Make only 1/8th turn adjustment, then retest before making another adjustment.

Remember that tension testing and readjustment are a necessity when sewing. The same tension that will work with light weight thread and fine fabric will most likely not work when using heavy thread on drapery fabric. Get comfortable with making tension adjustments to get the ideal tension for each project.

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.

My handheld machine won't sew any fabric.the thread just flaps in and out of the fabric but its not sewing the fabric


Sounds like it is not catching the bobbin thread which is how it makes a stitch. Try re-threading top and bottom threads. Or perhaps your tension is far too loose. Adjust tension higher or lower to test.

the thread that you changed to is a lighter weight thread & the top tension must
be adjusted to work well with the thread & fabric
needles & thread have to work togeather with the fabric,, & the tension needs
to be check every time thread & needles & fabric are changed

Top thread tangled in bobbin.


try changing the needle---flat side goes to the back side of the machine
also check the top tension
depending on the fabric your sewing on--the needle & thread have to work
with the fabric--example light fabric needs a different needle & thread than
a heavy fabric
check to see if the thread is coming off the thread take up lever when you
sew.

I needle comes unthreaded whenever we try to sew. We've both tried numerous times and it doesn't make a sitch. The bobbin seems to be done correctly b/c the bottom thread comes up with no problem....


first let's deal with the needle becoming unthreaded, Keeping the needle threaded is easy, always keep thread tails of 3 to 6 inches on the top thread & bobbin at all times, & make sure the thread tail are pulled behind the needle before you start to sew,, this will ensure that the thread will not come out of the needle when you start to sew.

you mention the fabric is thin,, do you have a needle that's right for the fabric your sewing?
thin fabric needs a different needle than blue jeans fabric, check your top tension & see what the setting is on, usually 3 to 5 is good.

when the needle & thread are right for the fabric then the sewing is good.

also clean under the needle plate & bobbin area for loose threads or lint

also it's a possibility that the machine could be out of time & would need to be serviced by a sewing machine repair shop-as they have the tools for the job

Sewing a bunch of thread from the bottom, this stops the machine from actually sewing


Yes, it does. There are a couple of reasons the bobbin thread could be bunching up on the underside of the fabric. It could simply be that the machine needs cleaning. Take the bobbin assembly out, brush all the old lint out as best you can, reoil the machine once it's all clean, and make sure there aren't any little bits of thread caught in the bobbin assembly. Rethread the machine (carefully) and change the needle. This solves the problem usually--especially if the machine was sewing along fine and the problem develops suddenly. '
The other thing to check is your tension. It could be that the top tension is too loose. But different color thread in the top and in the bobbin, stitch a few inches (be sure to held the top and bobbin thread ends behind your needle as you start to stitch) and check. WIth the pressure foot down, adjust the tension, and stitch again. Keep stitching, checking, and adjusting until you see little if any bobbin thread on the top or top thread on the bobbin.
Another thing to reminder: use the appropriate thread and needle for the fabric you're sewing.
Let me know if this works, ok?

When i use sewing cloth in backside the thread will too loose then i use tension tight it correct in 8 number but manual book says 4 or 5 is correct wat can i do help me


Unthread your machine and set the tension to 4.5. rethread your machine up to the needle and then put the presser foot down. If the thread pulls hard, your machine is threaded right if it pulls easily, the thread is not thru the tension wheel correctly.

Rule of thumb:: loops on the top, problem on the bottom.
loops on the bottom, problem on the top.
