The device for filling and/or emptying the shuttle has members for holding the shuttle (1) in place while it is being filled or emptied, and members for opening the closing member (9) and for filling and emptying the shuttle (1), the mutual position of the members for holding the shuttle (1) and the member for opening the closing member (9) at the filling and the emptying station being such or capable of being made such that the end of the opening member pushes through the opening (8) of the shuttle (1) into the shuttle to a distance beyond the closing member (9).
