ABSTRACT:
A bale opener includes a carriage arranged for a back-and-forth travel in a path along a fiber bale series; a tower supported on the carriage and a cantilever mounted on the tower and arranged for vertical displacements with respect to the tower, an opening device supported in the cantilever and arranged for removing fiber from the bale tops during travel of the carriage; a sensor assembly arranged for travel along the fiber bale series for emitting first signals characterizing bale heights; and a control device operatively connected to the sensor assembly for receiving the first signals. The sensor assembly comprises two sensors mounted on the tower or the cantilever and spaced vertically from one another. There is further provided a length position determining device for generating second signals representing longitudinal positions of the cantilever along the travel of the carriage. The length position determining device is connected to the control device for receiving the second signals.
