That's an idea WD. Similar to what was suggested by Dalpuri:
I've also used a similar method when making parathas.
Instead of rolling out with flour and a pin, ive pressed the balls of dough in my electric chapati maker for 10-20 seconds. They blister slightly and a waxy type of skin is formed. These can be stacked up together without the need for dividers for frying later.
Interesting idea of the pasta roller Natterjak. May have potential but i don't have one to give it a try
As for the funnels, I can see the logic behind it. You'd have to be careful not to overfill though, and then you've still got to get the little bugger out and close it up. What happens if it decides to stick itself to the funnel

;D
Or we could nip down the local general store and clear their food cabinet of their home made samosas - if you're lucky enough to have a store that makes them ;D I'm lucky, I do and they're real tasty.
But then again, just think of all the fun you'd be missing out on and that special moment when all your efforts come together to produce that perfect little triangular snack

I now am feeling the need to mix up some dough and knock out the cases today and possibly boil up the spuds :
