· From the analysis of belt slip, it can be seen that the smaller the wrap angle of the roller, the smaller the friction coefficient, and the conveyor belt departs. The greater the minimum tension at the point, the easier the tape will slip. In the design, the wrap angle between the roller and the tape should be appropriately increased.
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).

Static friction is friction between two or more solid objects that are not moving relative to each other. For example, static friction can prevent an object from sliding down a sloped surface. The coefficient of static friction, typically denoted as μ s, is usually higher than the coefficient of kinetic friction.
