ABSTRACT:
A bale opener includes a housing moved along a travelling path, and an opening roll which is mounted in the housing for removing fiber tufts from faces of fiber bales arranged in a series along the travelling path and which has a longitudinal axis lying in a plane oriented perpendicularly to the travelling path. There is further provided a suction device that generates a suction stream within the housing for removing, from a zone of the opening roll, fiber tufts detached by the opening roll from the fiber bales. A pressurized air stream generating device blows air in an upwardly inclined direction into the housing for essentially preventing fiber material from dropping off the fiber bales over upper edges thereof.
