ABSTRACT:
This disclosure relates to a method of removing a generally uniform layer portion of fibrous material from the top of a bale of compressed fibrous material and loosening the fibers of the layer portion during the removal thereof by providing a bale of relatively compressed fibrous material having a predetermined upper surface area, providing a suction hood having an overall area corresponding in size generally to the upper surface area of the fibrous bale, creating at least two spaced linear areas of suction across the overall area of the hood while preventing the creation of suction between the two linear suction areas, positioning the suction hood in overlying contiguous relationship to the bale upper surface area whereby the suction draws the fibrous material upwardly across the overall area and loosens the compressed condition thereof to a generally fluffed state through a uniform depth thereof, raising the suction hood to remove a general uniform depth of the loosened fibrous material across generally the entirety of the predetermined surface area, and subsequently discontinuing the suction to release the loosened fibrous material layer portion from the suction hood for subsequent processing.
