An apparatus for opening fiber bales includes an opening member arranged for travel along serially arranged fiber bales to execute opening passes; a grate including parallel-spaced grate bars having an operative position in which they extend parallel to the direction of travel of the opening member and press down on an upper surface of the bales. The opening member has opening elements projecting through clearances defined between adjoining grate bars. The operative position of the grate is varied substantially in a horizontal direction transversely to the direction of travel of the opening member and relative to the opening elements, whereby ridges of bale material formed underneath the grate bars are periodically exposed.
