Abstract
A bale opener has an opening device arranged for a horizontal back-and-forth travel above a row of fiber bales. The opening device includes two parallel-arranged and horizontally oriented opening rollers provided with teeth. The opening rollers are spaced from one another in a direction parallel to the direction of back-and-forth travel and each opening roller has an axis of rotation oriented perpendicularly to the direction of the back-and-forth travel. The opening device further has a bale hold-down device through which the teeth of the opening rollers project for penetrating into upper faces of the bales and a suction device for removing fiber tufts detached by the opening rollers. The opening rollers are codirectionally rotated during the back-and-forth travel of the bale opener.
