The pression of the belt segment and the grooved plate was achieved with a universal Zwick/Roell Z050 testing machine in the temperature chamber. The tests were conducted at four different temperatures, which enabled us to determine the influence of the temperature on the mechanical properties of the belt rubber. In Fig. 12 the pression force versus the deformation of the belt segment is presented. It can be assumed that the main deformation of the belt segment is due to the deformation of the soft friction rubber layer.
