Adler 269-373 missing stitches

Hi Yanni,

This is my first time on any forum but for what it is worth i think Eric is most correct Spongy spots and hard spots will often cause this problem, but further a new needle will often solve it. The tip can have a very slight twist and deflect sideways away from the hook. Next the hole in the needle plate should not be too enlarged out as this allows the softer leather to go in and hold the thread elastically against the needle and miss the hook. The gap on the foot being too large will create the same problem. Check carefully for any catching on the thread return spring and polish up any bits if needed. Last try lifting the foot by hand upward and if it feels grabby work out why and fix. Silicon spray if you must.

Best of luck Brian

PROBLEM SOLVED!

Thanks a lot for all the replies, I called an engineer from the factory next door and sorted it out.

He basically told me if there are skipped stitches check the hook first!

What happened is I had for sometime a lot of play on the feed dog because of a non original spacer next to the feedog.

That was kept of breaking needles for a while due to the play of the feedog and the needle not always hitting the centre of the feedog.

As a result it had also blunted/rounded the tip of the hook. I also found a small piece of broken needle inside the hook and also had to move the hook assembly as close to the needle without touching...all this 0.10mm business is rubbish...you just get it as close to the needle so you no longer see any light behind with the magnifying glass.

Then we sharpened the bottom up and inside tip of the hook( never the outside he said) to make it like a needle point and it now works again like a dream, no more slip stitches...

 

Thanks again...

A wiggly feed dog will cause problems, no doubt.
