ABSTRACT:
A fiber bale opener includes a downwardly open housing which is adapted to be supported above fiber bales to be opened and which accommodates an opening roller having an axis and being arranged for detaching fiber tufts from upper bale surfaces. In the housing there is further arranged a suction duct through which fiber tufts detached by the opening roller are adapted to be removed by a suction air stream flowing therethrough. The suction duct has two lateral walls which are facing one another and which are spaced from one another in a direction parallel to the roller axis. One lateral wall has an upwardly extending first oblique air guiding face and the other lateral wall has an upwardly extending second oblique air guiding face. The first air guiding face projects into the suction duct to a maximum extent of between one fourth and one third of a width dimension of the suction duct measured parallel to the roller axis at a location adjacent the opening roller and further, the second air guiding face has a bent portion for changing an upward inclination thereof.
