Abstract
An apparatus for opening textile fiber bales includes a bale opening arrangement adapted to travel parallel to the length of the apparatus along serially arranged fiber bales. The bale opening arrangement comprises a bale opening member having a plurality of opening elements for penetrating, in an opening zone, into the fiber material of the bales at an upper face thereof and a grate formed of parallel-spaced grate bars for engaging, in an operative position of the grate, the upper face of the bales. The opening elements of the opening member project in between adjoining grate bars in the opening zone. The grate bars, when viewed in their operative position, terminate in a free end in the opening zone.
