ABSTRACT:
A method of operating a bale opener having a carriage arranged for back-and-forth travel along a plurality of serially arranged fiber bales, a tower mounted on the carriage, a cantilever supported by the tower and projecting generally laterally therefrom, an opening device accommodated in the cantilever and arranged for removing fiber from bale tops, and a sensor arranged to travel in a path along the fiber bales. The method includes the steps of sensing the presence of a length boundary of the bales by the sensor and applying first signals, representing such presence, to a control device. The sensing step comprises the step of sensing the bale boundary by the sensor directly. The method further comprises the steps of determining positions of the sensor along its path of travel, applying second signals representing such positions to the control device, and comparing the first and second signals in the control device for determining locations of length boundaries of the bales along the path of travel of the bale opener.
