ABSTRACT:
In an apparatus for opening bales of textile fibers, a deflecting member for the fiber flocks is arranged within the housing and extends in the longitudinal direction of the opening roll. This deflecting member deflects fiber flocks supplied on the one side of the roll into the conveying shaft, at least largely prevents leakage air coming from the other side of the roll, and is able to shift in position under the action of blows which act on it during bale opening, for example blows caused by foreign articles. The deflecting member is pivotally secured in the region of its longitudinal edge adjacent the roll, to respective links for executing pivotal movements about an axis which extends parallel to such longitudinal edge. The opposite ends of the links are in turn pivotally journalled on the housing. Moreover, an extendible and retractable unit is provided for changing over the direction of the deflecting member in accordance with the direction of rotation of the opening roll.
