The puzzler got me thinking about flat fan belts. They are used today where ever ultra high speed and low friction are required. (They are the blades in bandsaws, for example.) Ever wonder about the contour of the pulley face, and what keeps the flat belt centered on the pulley? For the curious, t…

Low friction? Friction is GOOD when using belts. Perhaps you meant high flexibility (low internal friction)?

I meant high efficiency, i.e., little to no loss in power conduction. V-belts have higher internal friction (they are thicker and stiffer).

Internal friction. That’s what I figured you meant. It didn’t come out clear.

Some of us are more curious than others.

I wonder about it, and looked it up, many years ago. So far back I don’t even remember. I have an enquiring mind…

Monkeys are curious too. JUST KIDDING!!!

Give me a break: Moe B. Usse? Hummm…Mobius?

I am hoping Ober made it past the front lines before they discovered a twist in the belt would make it wear faster.

There’s no way the mobius strip answer would work. The belt would not rotate around leaving the twist in one spot between pulleys, but the tiwst would rotate with the belt and go over the pulleys, doing nothing to extend the life of the belt. Now if something could be engineered in to keep the twist…

Honestly, I never have wondered!!
