Abstract: A multiple bale opening apparatus for opening fiber bales which includes an inclined conveyor for supporting a longitudinally-extending rank-and-file array of bales in a single, uniformly inclined plane along the entire length of the inclined conveyor, and including a bale-receiving end for receiving bales to be opened, a fiber plucking head carried by a fiber conveyor truck for moving along the length of the inclined conveyor and plucking a layer of fibers from a top surface of the array of bales supported by the inclined conveyor, the fiber plucking head mounted for movement in a horizontal plane to maintain the top surface of the bales in a horizontal plane along the length of the inclined conveyor as the fiber is plucked from the top surface and the depth of the bales is progressively reduced along the length of the conveyor by the movement of the bale plucking means.
