  • Patent number: 8051771
    Abstract: An improved mechanism for directing movement of a plurality of side-by-side belts in a round baler wherein a bale chamber is optimally configured for bale core formation thereby reducing the need for an aggressive surface on the belts to initiate rotation of the incoming crop material. As the bale expands, the improved mechanism enables the unguided span of belts surrounding the periphery of the bale to be minimized by positioning intermediate guide rolls generally equidistantly from idler rolls bounding the belt guides defining the bale forming chamber. Further, the improved mechanism reduces the friction force between the crop and the belts necessary to initiate crop rolling for bale core formation enabling smooth-surfaced belts to be used which reduce trash generation.

  • Patent number: 7574955
    Abstract: A roll mounting apparatus for the lower bale forming roll of a round baler enabling the roll to be selectively installed in one of two positions using common mounting components. The normal roll mounting aperture in the side wall allowing the roll shaft ends to extend therethrough is elongated to permit limited radial movement of the shaft. A reversible adapter connected to the main frame (one on each main frame side wall) at each end of the shaft covers a portion of the elongated aperture and provides a mounting connector (threaded hole) to replace a fastener receptacle eliminated by elongation of the aperture. By repositioning the adapter, the shaft may be displaced radially to one of two positions, thereby allowing the roll to be installed in an optimum location for the crop material or to enable manufacturing flexibility. The roll can easily be relocated to the other position, as necessary, using bolted connections securing the adapter to the side walls and the roll shaft bearing to the frame and adapter.

  • Patent number: 6550218
    Abstract: The device consists of a mechanism to place netwrap over the edge of a cylindrical bale that is created in a variable/fixed baling chamber of an agricultural round baler. The invention consists of a netwrap delivery system having of a pair of arms pivotally affixed to the outside of the baling chamber sidewalls. Also attached to the arms is an assembly frame. An actuator controls the pivoting motion of the delivery system inserting the netwrap between the stationary dimple roll and the pivot roll of the sledge assembly. Positioned outside the sidewall and between the outer frame member is a transition area. The netwrap is inserted between the stationary dimple roll and the pivot roll as well as into the transition area. Because the width of the delivery assembly is wider than that of the cylindrical bale, a portion of the netwrap is inserted over the edge by use of the transition area.

  • Patent number: 5054387
    Abstract: Apparatus for wrapping cylindrical bales of crop material with twine includes a feed roller, a knife, and a twine arm connected to an electrical actuator for dispensing twine. The electrical actuator is extendable and retractable in order to cause pivoting movement of the twine arm between a rest position, a twine dispensing position and a twine cutting position. A first link is connected between the electrical actuator and a crank lever, and a second link is connected between the crank lever and the twine arm. Extension of the electrical actuator moves the twine arm from the rest position to the dispensing position and simultaneously results in the feed roller being driven. Retraction of the electrical actuator moves the twine arm from the twine dispensing position toward the twine cutting position while the feed roller continues to be driven. When the electrical actuator is fully retracted, the twine arm is moved into the twine cutting position and the knife is actuated.
