Abstract
An arrangement for extracting fiber flocks from textile fiber bales includes a fiber flock extraction member which passes between and projects to a predetermined extent beyond respective grid bars which rest on the bale surface during the extraction operation, for the extraction member to extract the fiber flocks from the surface layer of the bale. The extent to which the extraction member extends beyond the grid bars can be adjusted in dependence on the fiber type. To achieve this, the grid bars are movable with respect to the extraction member by respective screw-threaded spindles. This adjustment is performed under the control of a suitable control system, especially a microprocessor, such that the extent of projection of the extraction member beyond the grid bars is automatically accommodated to the fiber type of each bale or bale group from which the fiber flocks are to be extracted during a particular extraction operation.
