Zig zag

[Uwe]

Perhaps a Diver-Suits Blindstitch Sewing Machine will do the trick.

 

Or a Strobel style machine:

Good info., first thing I would look at is a top and bottom feed zig zag, here are two;

Consew 347R Series (WS is for wet suit) feed off the arm type

Consew 146RB-1A-1WS flat bed type

I have a customer who wants neoprene compression sleeves made and all of his examples are all zig zag stitched. He is wanting large quantities made and I'm not opposed to buying a machine to do the job (who doesn't like a new toy) but I'm unsure what machine to get. I've been looking at singer 20u models but don't know their limitations i.e thread size,foot lift. Any knowledge or opinions on these machines or any other zig zag capable machine is much appreciated 

20u and 021d201 series are embroidery machines in essential, because despite have power to sew even a soft leather or jeans, with appropriate needle, this machines was made to speedy and no to power.. i have a 021d, but I'm restoring now a durkopp 252-4(similar/clone of singer 107/143)..its more slowly, but i can sew ¼ of leather easily....
