ABSTRACT:
A bale opener for removing fiber tufts from top surfaces of fiber bales assembled in a series includes a carriage for travelling back-and-forth along a generally horizontal, first path of travel along the fiber bale series; a tower mounted on the carriage for travel therewith; a fiber tuft detaching device extending from the tower and movable relative to the tower along a generally vertical, second path of travel; and an incremental rotary displacement signalling device including a shaft; a toothed rotary element mounted on the shaft; a counter element meshing with the rotary element which is movable relative to the counter element; and a signal generator coupled to the toothed element for generating signals as a function of rotary displacements of the toothed element. One of the elements is mounted on the detaching device (or other co-travelling component) and the other element is mounted along one of the first and second paths of travel for generating signals as a function of displacement of the detaching device along at least one of the first and second paths of travel.
