Abstract
A fiber bale opening device (1.1) with a bale opening organ (30) moves in the direction of the arrow A over a row of bales (4) to open fiber flocks from the surface of the bales by means of the opening rollers 6a and 6b. The opening rollers are inclined in such a way that the bales are opened with an angle .gamma. to the horizontal. The opening rollers (6a and 6b) are moreover adjustable to incline in such a way that the depth of penetration (T.1) of the leading opening roller correspond substantially to half the penetration depth (T.2) of the trailing opening roller. These penetration depths can, on the one hand, be effected by the setting of the opening rollers. Movement of the opening organ (30) in direction (D) sets of the opening rollers in order to retain the opening depth (T.1).
