  • Patent number: 3949448
    Abstract: Apparatus and method for removing fibers from fiber-laden pallets is disclosed in which the bulk of fibers is removed in a primary unloading area thus leaving a thin layer of fibers that are removed by a surface cleaning device. The surface cleaning device included a multiple-blade rotary sweeper which is spaced vertically above the uppermost portion of a pallet to enable the pallet to move therebelow without mechanical interference with the rotary sweeper. A cowling encloses a portion of the periphery of the rotary sweeper to increase the efficacy of fiber removal by the rotary sweeper. The rotary sweeper mechanically engages an upper portion of the thin layer and removes it from the pallet. A suitable gas blast device impinges upon the pallet surface at a location substantially below the rotary sweeper to engage a lower portion of the thin layers of fibers. The gas blast device causes fibers to be lifted upward and into mechanical engagement by the blades of the rotating sweeper.
