The 'industrial machine' is a misnomer. A machine which can saw fast is usu. called 'industrial' for it saves time.
The peccant part is the "walking foot" or free arm.
This type as it's name suggests, steps over the material passed, not trying to drag it like the 'normal' sawing machine. I had a leather business, sawing leather wests, pants, jackets and we used an 'industrial walking foot' machine.
It handled all the heavy duty sawing with aplomb.
Never tried a sail be sawn on it thou, but the idea is the same.
The machines down at the local loft are all so called 'walking foot' machines.
The old Singers are a class on their own as in those days they did not have the walking foot invented yet and all the machines were built like they should have built today, using metals not crap plastic.
Sam and LC beat me to it by minutes but it's the same, nevertheless !
