I'm trying to find a grommet or machine that will act like a button hole. I don't want to sew a button hole

Question

I want to reinforce a slit in fabric, but don't want to sew a button hole. Does anyone know a grommet machine out there that does oval or rectangular grommets? It is for mass production so sewing a button hole would be too time consuming.

Answer 1

Why don't you just use Heavy duty snaps,

or is it going to be used to thread rope or line through?

Answer 2

If you are going into REAL mass production, buy a dedicated button hole sewing machine.

Answer 3

You would need a specialized machine for that particular shape.  Most grommets are round.  Could you not locate a factory that specializes in sails for boats?  You could find out who makes their machines, (or tent makers) then contact that manufacturer for the modifications you need.

Good luck.
