TonyGreen3455 Report post Posted January 9 help needed a bit strange issue, I can't even describe in which area exactly - the threading, the tension or machine itself. cb3500 clone. the thread 207/15 the thread, which is initially threaded as usual (via correct way, I hope) when sewing, jumps out of the upper tension. just comes out from between the plates and all the tension disappears. was trying different ways to thread, screwing tension/plates up - all the same. thread 207 does not want to be in between the plates when sewing. imho most logical way to fix it - to put extra thread guide after the tensioner, but there in no any hole/screw to connect it at all. no any way by the design. with a thread 277/10 no such problems, everything was fine. so, where I'm wrong? or it is hardware issue and smth to be replaced/fixed/installed? any advises welcome Quote Share this post Link to post Share on other sites
CowboyBob Report post Posted January 9 TonyGreen3455 You should have a spool pin in the center on top of the machine,run the thread through 2 of the holes & it will give enough pre-tension to hold it. Quote Share this post Link to post Share on other sites

BlackDragon Report post Posted January 9 2 hours ago, TonyGreen3455 said: On your top tension disk, is your thread seated completely in between the disks. In the picture it looks like it just sitting on top instead of it sandwiched in between. Give a good tug down so it sets in. Quote Share this post Link to post Share on other sites

Dwight Report post Posted January 9 49 minutes ago, TonyGreen3455 said: you mean - this one? threaded as per video - through single hole, but will try it for sure, thank you! That is the culprit . . . I take my 346 thread thru the other side of the post . . . wrap once around it . . . and come thru it again starting on the same side as the first thread. It was a guess . . . first time I threaded my 4500 . . . and has worked perfectly for the last 3 years or so. Try it . . . I think you'll like it. May God bless, Dwight Quote Share this post Link to post Share on other sites
DieselTech Report post Posted January 9 Isn't his thread path thru the top tension disc wrong? Shouldn't it look like this? Granted this is a Cobra class 4, but I think the threading is the same. Quote Share this post Link to post Share on other sites

I though the same thing so I looked at a couple youtube videos and for the Cowboy it's different than the Cobra, based on those videos. Quote Share this post Link to post Share on other sites

Ok sorry. I thought they both used the same threading path. Quote Share this post Link to post Share on other sites

Give a good tug down so it sets in. those pict with a thread on the top taken after that. at the beginning put it in between plates completely down - it is why a bit surprised with such issue. confused - thread itself is either too thin or slippery many thanks to all for your opinions - will try it Quote Share this post Link to post Share on other sites
TonyGreen3455 Report post Posted January 9 followed all recommendations and on top of that moved thread guide before the upper tension a bit down, just below the axle of the tension itself - see pict. very happy with a result, whatever it's a right way or not. many thanks to all again. coda Quote Share this post Link to post Share on other sites

The funny thing is that when I saw this thread I found pics of how the Cobra is threaded and mine was totally wrong. I don't know how I was sewing anything with how wrong it was but it worked.

This is a topic that I done sometime ago about the different top threading methods and may help. On my class 441 I follow the method of threading the top thread of the Juki TSC-441. kgg Quote Share this post Link to post Share on other sites
Uwe Report post Posted January 10 Also this path look suspect. You have the thread caught between the windings of the check spring, which adds tension in a spot where it shouldn’t. Quote Share this post Link to post Share on other sites

Damas Report post Posted January 11 I had the very same problem with my Hightex CB3200 recently. It came from the thread... It was making pigtails when unspooling and when the pigtail arrived in upper tension, the thread was popping out... Try with a different thread and see if that was your issue Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted January 11 Here's one part of the problem of thread coming out of tensioners. I found out that not every spool of thread unwinds smoothly. Some, especially black thread spools are what I call "twisty or coily." They unwind with a twist that's in the direction they were wound in. The worst offender is from Weaver. Sometimes, thread is double-dyed to get a solid black color. This really stiffens the thread and can cause it to become a coil that twists around guides and jumps out of tensioners. I have come up with a way to counteract this twist. This is specific to the Cowboy and Cobra 441 clones, and similar machines that have a top guide post containing at least two holes that are about an inch apart. My solution is to feed the top thread through the top hole, then turn it counterclockwise and feed it through the bottom hole. From there, it goes to the eyelet under the tension disks. I also lowered that eyelet to get a tighter feed into the disks. I've never tried feeding the thread back through that eyelet because my reverse feed seems to counteract the twisty thread.
