Abstract:
A method for determining a property of a belt, to allow for non-linear belt motion, comprising:determining an arrival of a predetermined feature on the belt; determining at least one belt edge value of the belt; generating at least two consecutive plots including a previous data plot for a previous plot and a current data plot for a current plot based on the at least one determined belt edge value at positions relative to the predetermined feature; comparing the current data plot to the previous data plot, wherein if the current data plot does not match the previous data plot, the belt is adjusted to compensate for non-linear motion along the length of the belt; and continuing to generate data plots, comparing the current data and previous data plot and adjusting the belt until the current data plot matches the previous data plot so that a control condition is obtained in which non-linear motion along the length of the belt has been eliminated.
