Abstract: A method of producing bales of agricultural products includes wrapping a bale with a wrapping material, discharging the fully wrapped bale from the press, and forming a new bale, with an intermediate storage of the product in the press retained as short as possible by overlapping of some of the method steps, so that the time required from the beginning of wrapping of a finished bale to the beginning of forming a new bale is very short.

Abstract: A wrapping of netting is disclosed for a round bale of agricultural blade crops. The use of netting as a wrapping permits the elimination of all additional measures for fastening of the wrapping which have so far been customary and necessary with any other wrapping materials.

Abstract: A roll bale press apparatus for rolling and wrapping harvested agricultural material comprises a prechamber that is disposed forward of a press region. A variable position pickup device is operative in a first position thereof to direct harvested agricultural material through a first inlet orifice into the press region, and is operative in a second position thereof to direct harvested agricultural material into the prechamber. The apparatus includes a second inlet orifice above the first inlet orifice, between the prechamber and press region, through which harvested agricultural material may pass from the prechamber into the press region, and the prechamber includes a transport mechanism for conveying material in the prechamber upwardly to the second inlet orifice.
