Abstract
A bale opener for detaching fiber tufts from a top surface of a fiber bales series includes a tower for travel along a series of fiber bales in a direction of travel; a detaching device supported by the tower and including a rapidly rotating detaching roll; an arrangement for vertically moving the detaching device relative to the tower; an arrangement for angularly moving the detaching device about a horizontal axis oriented perpendicularly to the direction of travel; and a bale transporting device for advancing the fiber bales in a horizontal feed direction. The bale transporting device includes a conveyor belt and first and second end rollers supporting the conveyor belt. The first end roller is situated downstream of the second end roller as viewed in the horizontal feed direction. There is further provided a control arrangement for operating the conveyor belt to advance the fiber bale series in the horizontal feed direction and for simultaneously positioning the detaching device immediately above the downstream end roller upon completion of a working pass of the bale opener in a direction coinciding with the horizontal feed direction.
