Abstract
A method of operating a bale opener arranged for alternating forward and reverse travel along a series of fiber bales and having an opening device including an opening roll for removing fiber tufts from top faces of the fiber bales. The opening roll has unidirectionally inclined teeth. The opening device further has a grate arranged for pressing down on the top faces of the fiber bales and formed of grate bars between which the teeth of the opening roll project. The method includes the following consecutive steps: lowering the opening device immediately prior to a forward working pass, whereby the opening roll executes a downward feed motion; moving the opening device in a forward travelling direction for causing an execution of the forward working pass; and moving the opening device, without an immediately preceding lowering thereof, in a rearward travelling direction for causing an execution of a reverse working pass.
