  • Publication number: 20020189199
    Abstract: A large round baler is equipped with a net wrapping mechanism for wrapping a bale with net material that is wider that the width of the baling chamber so that the net material extends over the opposite ends of the bale. The baler has a baling chamber defined in part by a plurality of bale-forming belts mounted in side-by-side relationship on a plurality of belt support rolls extending between opposite sidewalls of the baling chamber. The net material is fed beneath the discharge gate of the baler to a crop inlet located between a lower front belt support roll carried by the discharge gate, the net being carried into the baling chamber by a fore-and-aft runs of the belts that extend between a lower rear and the lower front belt support roll, and carry the net along a guide surface defined by a plurality of channel members respectively located beneath the fore-and-aft runs of the belts.

  • Patent number: 6272816
    Abstract: An apparatus for wrapping net about bales formed in the baling chamber of a large round baler is arranged such that the net material supply roll is pressed directly against the driven wrap material feed roll by a pressure roll carried by a pair of transversely spaced lower arm portions of a lower arm section of a vertically swingable pressure arm assembly that also includes a separate, upper arm section. The force pressing the pressure roll against the supply roll originates with gas springs coupled to a linkage that is in turn coupled to transversely spaced upper arm portions of the upper arm section, these arm portions carrying respective force transfer rollers that engage respective intermediate sections of the lower arm portions.
