One aspect is the friction of the underside of the belt. In practice, this is not critical because it is low. Regardless of whether a table of steel or of wood is used, the coefficient of friction is.

Conveyor belts with a low coefficient of friction - Nitta Corporation

The fabric used in Nitta's curved conveyor belts reduces the coefficient of friction to 0.14 (coefficient of friction µ of backside on aluminum). This makes these types of conveyor belts particularly suitable for other applications. Not only will it be a solution for friction critical applications but also for applications where energy.

between the pulley and the belt. There are three ways to do this. First, use as large a diameter of a pulley as possible. Second, provide as much belt wrap as possible, and finally, increase the coefficient of friction between the pulley and the belt by lagging the pulley. It is also necessary to always use FLAT FACED PULLEYS.

Accumulation Belts - Forbo

The particularly stiff design of the belts ensures level conveying in larger belt widths. So pushing unit goods on or off from the side is no problem at all. Minimum friction coefficients between slider bed and underside and accumulation goods and top face must be maintained so that required power and wear and tear is kept.
