An apparatus for opening fiber bales has a traveling opening member propelled along serially positioned fiber bales to execute opening passes, a grate having parallel-spaced grate bars extending, in their operative position, in the traveling direction and pressing down on an upper surface of the bales. The opening member has opening elements projecting through the clearance defined by adjoining grate bars. During the opening process the relative position between the upper surface of the bales and the grate is periodically varied for periodically exposing ridges of bale material formed underneath the grate bars.
