what sewing machine is this?

[wolfago]

hi, this sewing machine was almost given to me. but other than the initials (643-110) there is no producer. there is also the writing ITALIA-9002. I need to figure out the make and model to know what thread and needles to use. I did a test with 2 layers of 14oz leather and it works great, but that's also the maximum thickness of the presser foot lift. it has transport only below

It´s a clone of the Singer 45K or Adler 5. It´s a drop feed machine w/o reverse. The Adler 5 or Singer 45K manual will work for this machine

Since it is made in Italy I would guess it was made by NECCHI.

So it´s a NECCHI 643-110 I´d say.

I also believe it's a clone of the singer 45k, but the necchi 643-110 doesn't exist. the important thing is to use a manual, so I will use the singer 45k. Can you tell me what maximum thickness I can sew? I would need this to sew the saddle skirts, 2 layers of 14 oz plus the shearling. What needles and maximum thread thickness can I use? Thank you

But the NECCHI 643 seem to exists and the 110 is (as on other sewing machines too) the subclass that describes technical details or how the machine was set up when it once left the factory. However NECCHI machines of the Class 643 are quite rare as it seems.

This is a NECCHI 643 but set up as darning machine:

So I think the data plate on the machine "could" be right - not sure though.

I have a 45K and I know the Adler 5 - they usually can sew 12mm leather. But it depends on how the machine is set up. The Singer 45K´s and Adler 5 usually have a much larger / heavier hand wheel you at least need a powerful servo motor (would recommend 750Watts) with small 50mm pulley and I personally would add a speed reducer as well for slowing down the sewing speed and increasing the torque.

I`m can use needles up to size 250 (metric) but I seldom do I usually sew with 180 or 200 needles with 11/3 (metric) thread.

The needle system on these machine usually is 328 or 214x2

I just went trough my sewing needle records and found that NECCHi made a machine class called OPC. Maybe it is an abbreviation or maybe OPC was an earlier class and they later remanded it with a number system or the other way around - I don´t know.
