Thread tangling around the needle...

[Dantan]

Hi,  

I have an Adler 104-64,  that is suddenly giving me problems.

 

I am stitching two to three layers of heavy-ish belt leather,  and have not had trouble before,  but today,  I can not for the life of me get it to stich more then 5 stitches before it starts skipping stitches, and then stops stitching completly... and when I look at the needle,  some how the top thread is wrapped around the needle.

 

I cut the thread...   put it into the needle correctly, and same thing happens again.

 

Any suggestion?

 

Thank yuo i advance,   for any help!!

thread Wrapping around needle sounds weird . But start tracing down the problem . work back from the needle , needle bent/needle turned . the correct size needle and Skarf on correct direction to Hook or off-angle.
Had a needle strike lately ? . look/feel for a burr on needle/throat plate, burr on Hook .

Got thread with the right "twist"?

[Dantan]

So ,  in my own trouble shooting,  I changed the needle already....   I will have to check the hook for burrs...

 

the comment about the thread is interesting,  because the cone is about 3/4 empty,  and I have noticed that it has a lot more twist to it then it did when the cone was full/larger...   could this cause it?

 

This is the first cone of thread I have ever used on this machine...   On the cone it says

 

Bonded Nylon 66

Tex 135     1250 yards

Col:Black

 

Does that sound right?

You should be using a #22 or 23 needle with T135 thread. Are you? Also, make sure the top thread is feeding through the check spring, before the take-up lever.

[nylonRigging]

Your nylon is always going to be a little stiff and curly with memory of the wrap/tension, especially on the last 25% left on the Roll .

In your 1st post your saying that it sewed perfect until now ?? . ( if so ? )  then something has suddenly changed different . You saying ? .." you only used this one thread #size this whole time  . You Did not accidentally put wrong needle in by mistake ? You did not have Scarf pointing wrong direction to Hook ? . Your Needle is pushed-up all the way in needle bar ?

---> So, you saying suddenly now, It's dropping Stitch and shredding/tangled on ( top-Thread and needle ) and fast in first 5-6  stitched laid down . You need to ' start ' by close scrutiny of all related to Needle - Hook .

That sounds about right. The size of cone you are using is approximately 4 oz. There has be discussion on the problems associated with the 8 oz cones particularly black in colour from China in the past. I can see that the problems would be that much greater particularly when you get down towards the last 10 to 20 % with such a small cone. I would suggest replacing the thread cone with a new one of a larger size (1 lb would be best), check the needle and size of needle making sure it is fully seated and installed correctly.

Black thread is the worst for getting twisting. It is the most stiff thread because of the dyes they use to dye the thread.   I always told my production people to change to a new spool of thread halfway into a spool, especially on black.  As you use up more and more thread on a spool, it gets stiffer the closer to the end of the spool.  They used 1/2 spool left  strictly for bobbin winding.    Never had any problems following this approach.  We used #138 bonded thread in our production.  A&E's top nylon thread  made for automotive industry.  We were building hockey gear.   You may be having the same problem.  #23 titanium coated needles works great in this application.

This is an indication to me, that the check spring may not operate, as is should.

I agree!

This could be the problem if the thread isn´t the problem. The check spring should hold the thread under "tension" until the needle touches the material (+/- a little bit) so it may depend on the material thickens you are sewing how to set the check spring.
