ABSTRACT:
A bale opener is arranged for travel along a series of fiber bales and has a detaching (opening) device for progressively removing and hurling away fiber tufts from top faces of the fiber bales. The detaching device includes a generally horizontally supported opening roller having a roller axis and equipped with detaching teeth and a grate urged against top faces of the bales. The grate is formed by a series of side-by-side arranged grate bars spaced from one another in a direction parallel to the roller axis. The teeth project between adjoining grate bars and penetrate into top faces of the bales. A first imaginary contour line, defining a plane with the roller axis, interconnects tips of axially adjacent teeth of the opening roller and a second imaginary contour line, defining a plane with the roller axis, lies in an underface of each grate bar and interconnects side-by-side arranged grate bars in a direction generally along the roller axis. At least one of the first and second contour lines extends at least in part non-parallel to the axis of the opening roller.
