A poly V belt can be used to drive a bare drum if the drum is IIRC 10x

Contitech design guide for their poly v belts and it mentions it in
there. They've been doing washing machines that way for decades.

I've been using a poly v "serp" belt in place of the flat belt on my Logan
lathe for years . And did you mean dryers ? Most every dryer I've ever
worked on used a poly v to drive the drum .
Those too and I expect many other similar items out there. I didn't
think dryer as I've never owned one, I just hang my clothes on the line
in the garden or on the radiators in the winter when wet.
