PATCHING PROBLEMS


Recommended Posts

HELP! I have 3 zips to replace and my patcher is playing up. I don't have a manual or problem solving info. Just doesn't seem to want to stitch. Messed about with the tension and thought it was ok, then realised all the thread had gathered in a ball under the material. Have tried different needles etc. sometimes its doing 1 or 2 stitches then missing loads or just not catching a stitch at all. Any info would be great.

Have you tried turning the wheel manually and see if a stitch is formed. Do this without stitching on material. Just have a look and see what happens.

When there is a lot of material on the underside, the mayor problem is tension. Get the threat out of the machine. Rewind a new spool and use the same threat as you put on the upperside. Put everything together and try it.

Missing stitches can also mean that the moment your spool has to take the upper threat comes too early or too late. The needle goes down and takes the threat with him. Then the needle goes a little bit up and leaves a little piece of threat down where the turning spool has to take the threat. When this has happened the needle goes down again and the spool makes his turn. A stitch is formed.

This moment is crucial. When the underarm, the 2 saws that are in, are worn out, you never will get a proper stitch. This can be controlled by feeling if the spool can be turned left and right with a standing still machine.

Sorry for my English, I hope I have helped a little bit.

Claes and Adler are pretty much it, priced between £2800 and £3500, depending on whether you want to sit or stand and do your work. Both are very good, well made German machines with no part supply issues.

 

The only real alternative to those two machines are cheap, Chinese made, 29k copies that are dreadful, poor quality with dubious parts availability and cost more than you think once you have imported it :shock:

 

However, keep an eye on our Website for an announcment early in the New Year with regard to a NEW manual, short arm patcher :D Something we have under development :D

The old K60 would now have many worn parts, the sum of which make for problems on a big scale.

To identify which part is causing the problem is a mamoth task, one step at a time covering dozens of possibilities.

It's a hit & miss affair trying to identify the actual problem on this forum on an older machine.

 

I would look at the problem through a different channel.....£2800 for a new one... £25 a week just over 2 years pays for it.

£50 a week and you are into almost 100% profit after 12 months. Get a Claes.. very smooth and more versatile.

The reason thicker thread works is possibly because it increases the tension. Try removing the small plate on the side of the shuttle. Clean out any accumulated dirt and refit. Ensure the needle is fitted the right way round ie the longest groove in the needle facing to the left of the machine.

disc, you might want to try changing the grade of thread that you are using,, we had this problem,, now use a slighy thicker thread in bobbin than main thread, works for us, :D

Thicker thread is possibly compensating for worn parts ......rear of tension spring & bobbin case.. look for the tell tale groove in either. (after cleaning out the crap of course, as previously mentioned).
