Adding friction material to timing belts

[Knufire]

The vertical conveyor on 469s 2012 robot was a single strand of timing belt without any sort of friction material added to it. Worked perfectly.

So it looks like brush-on products are the way to go here. We'll have to do testing on how well it adheres.
It is for an intake mechanism, maybe for next year. Thanks!

You could always try a flexible latex caulk as a grippy material, or as something to attach a stretchy grippy material. I work at a lumberyard, and Lexel always advertises that their latex caulk is super flexible and adheres to everything, and from the display samples I've seen, I have no reason to dispute that. It might work, it might not, but there is only one way to find out.

I doubt a latex caulk would be tough enough.

Shoe goo adheres tenaciously and is tough and flexible.

I repaired a split tractor seat cushion with it. Four years of abuse and still no sign of letting go.

Years ago there was a track style robot in the PNW that used timing belts as the tracks. They were custom made timing belts that had a urethane backing on it. They were extremely grippy. They were like a 2" wide belt and if I remember right they weren't all that expensive considering their size and that they were custom built. I'd check with Gates and see if you can get a pre-done solution.
