A fiber bale opener includes a truck arranged for back-and-forth displacement along a travelling path, an opening mechanism carried by the truck and arranged for removing fiber from the top of fiber bales positioned along the travelling path and a suction apparatus for carrying away, by an air stream, fiber removed from the bales by the opening mechanism. The suction apparatus includes a suction duct extending in the direction of the travelling path and a throughgoing slot on one side of the duct, extending parallel to the travelling path. The suction apparatus further has a flexible cover belt which extends over the slot for sealing the inside of the duct from the environment and which defines an interstice within the truck. The interstice travels with the truck and provides a passage for the fiber from the opening mechanism to the inside of the suction duct. The cover belt extends in two superposed layers from one side of the interstice to one end of the travelling path and from the other side of the interstice to the other end of the travelling path. |
