Abstract
The bale opening machine is provided with a detection unit upstream of the bale opener for detecting the presence of foreign material at the surface of the fiber bale. In addition, an extraction unit is mounted adjacent the bale opener for removing the detected foreign material from a fiber bale. The extraction unit may include pairs of gripping jaws so as to mechanically remove the fiber material or may be constructed as a suction tube or tubes to pneumatically remove the foreign material. The detection and extraction unit may be mounted on a common side or on opposite sides of the bale opener.
