An interesting parameter to investigate is the theoretical contact points of the belt on the rollers. The contact point location for every roller can be estimated based on the two (left and right) dynamometer readings. The deviation angle δ between the roller centre and the contact point is defined as graphed in Figure 11 and expressed in Eq. (8).Web
