A large round baler includes a net wrapping device mounted to the rear and bottom of the discharge gate of the baler. A spare roll of net material is stored above an active roll of net material which rests upon and is caused to be rotated by the upper roll of a pair of net material feed rolls. The rolls of material are wider than the baling chamber of the baler and net spreader rolls, including both raised spirals and spiral grooves, are provided along the net feed path so that the net is at its full width when it arrives at the inlet to the bale chamber which is located at a lower bale-forming belt support roll extending between opposite sidewalls of the gate at the lower front of the gate. A pair of guide plates are mounted to the insides of the bale chamber sidewalls and extend about an upper portion of the circumference of a net spreader rolls located at the opposite ends of the belt support roll. These guide plates are shaped and positioned such that they perform the functions of creating a space between the bale end and the side wall for receiving marginal portions of the net, defining together with the side walls, a channel which leads from the net spreader rolls to the space created for receiving the net, rounding the end edges of the bale for better reception of the marginal portions of the net and deflecting crop material away from the spirals of the net spreader rolls so as to prevent them from wrapping with crop which would interfere with the feeding of the marginal portions of the net to be placed over the edges or corners at the opposite ends of the bale. First and second alternate embodiments respectively have only the recess or the entire shape of inner surfaces of the guide plates formed into the sidewalls. In the latter case, openings are provided in the sidewalls adjacent the trailing part of the formed shape, as considered relative to the direction of rotation of a bale engaging the formed shape.
In a large round baler including a bale-forming chamber defined in part by a bale discharge gate having opposite sidewalls spaced apart by a predetermined distance for forming bales in said chamber, lower rear and lower front bale-forming belt support rolls extending between and being rotatably supported by said opposite sidewalls of said discharge gate with said lower front roll defining a rear side of a crop inlet leading to said chamber, a plurality of side-by-side disposed bale-forming belts having respective fore-and-aft runs extending between and engaging said lower rear and lower front support rolls, said baler being equipped with a net wrapping mechanism including a wrap material guide surface underlying said fore-and-aft runs, the wrapping mechanism being operable for introducing a length of net wrap material into said crop inlet along a path defined between said wrap material guide surface and said fore-and-aft runs of said belts and in contact with said fore-and-aft extending runs of said belts whereby the net material is captured between the bale and the bale-forming belts, the improvement comprising:
An improved net wrapping mechanism for a large round baler, comprising:
