ABSTRACT:
A method and apparatus for use in sensing and correcting wander in a conveyor belt system employed to transport articles of greater width than the width of the belt itself, comprising for sensing deviations from a mean belt edge position at at least one side of the belt, generating a signal in response to such deviations, timing the duration of the signal, and an actuator operable to adjust tracking of the belt when the signal is generated for a period of time greater than that taken for the projecting portion of an article carried on the belt to move past the sensor.
