ABSTRACT:
A method of detaching fiber tufts from top surfaces of fiber bales which are set up in a fiber bale series along a travelling bale opener that operates with a vertically displaceable tuft-detaching device. The method includes the following steps: the bale height of all the bales of the series carried by the bale opener is determined by sensors; then data representing the bale height of the bale series, a vertical feed for the bales in the series having a minimum bale height and the determined bale height for all bales without feed change are inputted in a computer; then a proportionately higher feed for bales other than those having the minimum bale height is determined; and fiber tufts are detached from the top bale surfaces utilizing the predetermined feeds.
