Re: PVC Rollers?
I looked for a good belt comb pic.
Here's a cropped picture of a belt comb on our practice robot. It's thin polycarbonate rolled around the roller and riveted, we neglected to take the film off of the polycarb so it's white.
Our belt combs inside the robot (where both rollers need to contact the ball) usually cover only the top (non-contacting) side of the belt and don't go around the roller.
These belts were under a lot of side load, so we needed a lot of combing to keep the belts on track. We actually didn't rivet the spacers on the other side so the belts can walk as they please under load and move back into shape when the ball has passed.
