Abstract

Apparatus for removing fiber portions from a selected plurality of bales and delivering the fiber to a receiver, such apparatus including a head that is lowered into contact with the top surface of such bales to grasp fibers therefrom. A control system is provided which generates a signal when the head has traveled a predetermined vertical distance toward a bale, and the signal is used to vary the sequence of pick-up or the amount of fiber picked up, from the plurality of bales to assure that the plurality of bales are maintained at substantially even heights during the sequential pick-up of fiber therefrom.
