Abstract
An adjustable grid for the extraction arm of a bale-opener machine for adjusting the depth of penetration of drivable fiber extraction elements extending between the grid bars which are substantially tranversely arranged relative to the longitudinal direction of the extraction arm, has the grid bars biased by the spring devices into an abutment position corresponding to a minimum depth of penetration of the extraction elements. The spring force is selected such that the moveably arranged grid bars are displaced, in accordance with the bale hardness, in the direction of increasing depth of penetration of the extraction elements into a position which at least approximately corresponds to the appropriate depth of penetration of the extraction elements.
