RE:I remember the first time I saw a field with rolls of hay across it

Are they called 'swiss rolls' there too?

and if so does anyone know why-

The do look like a snack cake called 'swiss rolls' (among other things) but i was told the machine to roll hay and not bale it, was originally of swiss manufacture.

I have never see real sheaves, (i have seen decorative ones at restoration villiages, but what little i know about farming comes from 1) watchin 'Modern Farmer' in my very early childhood (it came on very early, before early morning cartoons) and 2)looking out car windows, and reading.
