False Thread Breaks on Hats

[Mike Garber]

I have an old red Amaya that we use alot for hats.
We have been getting false thread breaks (mainly on designs with thinner columns). It has been getting worse the last month or so to the point we have to turn off the thread detection to run a hat. When we sew flats the problem is gone. We follow the maintenance schedule and have been trying to trouble shoot for a couple months with no luck.

Anyone have an idea?

Thanks,
Mike

Try tighening up on the top thread feed just a little bit. If that doesn't work by itself, tighten the bobbin up a little tiny bit too.

We have been messing with the bobbin and material thickness. I have not messed with the column feed, its at 40.

Try about 35-38 and see (on a scrap, of course).

Mike,

In addion to what has been suggested...try taking the threadbreak sensor tube(the crome tube that runs across the front of the needlecase) and gently rotate it back and forth leaving it in a different position than when you started. The thread break sensor is very sensitive and given the age of your Big Red, it may be going bad and have to be replaced.

The first thing I think of is rotation of the sensor. For a while I thought it was working only to get worse. I will try lowering the column feed to 38 maybe. Do sensors slowly fade? The only thing that gives me hope is it doesn't do it on flats.

The threak sensor has a little solid state PC board and in my experience anything solid state is time limited and due to fail at the most in-appropriate time...so yes it can gradually degrade to total failure over time.

They are pretty easy to replace though...

You answered my next question....
Thanks for the info Rod and Gregory.
