Abstract
A bale opener arranged for travel along a series of fiber bales for removing fiber tufts from top surfaces thereof. The bale opener includes a toothed opening roll supported in an orientation transverse to a direction of travel and a grate formed of grate bars spaced in a direction transverse to the direction of travel and arranged for engaging the top surfaces of the fiber bales. The teeth of the opening roll extend between the grate bars for penetrating into the fiber bales during travel. There are further provided bale pressing elements supported by the bale opener on opposite sides of the opening roll spaced therefrom parallel to the direction of travel. The bale pressing elements are arranged to engage and press down the fiber bales during travel of the bale opener. A setting arrangement simultaneously vertically adjusts the bale pressing elements in opposite directions.
