Abstract
A fiber bale opening machine having an inclined opening roller (1) is provided with conveying apparatus (100) for stepwise displacement of fiber bales in the direction of the opening roller. The roller is movable transversely with respect to the direction of the displacement. The conveying apparatus includes at least one stationary support for supporting the bale and at least one shifting device for performing a repetitive movement cycle starting from an initial position and returning back to it. In the initial position, the lifting device is lower than the stationary support and the bale is supported on such support. Later the lifting device moves up to take over support of the bale and during this time it shifts in the direction of intended bale displacement.
