  • Patent number: 5020311
    Abstract: The invention relates to a method and to a device for producing highly compressed cylindrical bales from loose stalk material, such as hay or straw, which is picked up continuously and is compressed to form a rotating compressed roll which flows continuously in an axial direction. Individual compressed roll sections (bales) are successively cut off from the front end of the compressed roll. For producing dimensionally stable bales of varying length, the compressed roll, which is still subject to radial pressure, is bound automatically by a binder during its axially feeding and before a bale is cut off. The binder is delivered under tension and utilizes the rotation and feed of the compression roll.

  • Patent number: 4009653
    Abstract: To form round bales of fibrous agricultural material, windrowed material is fed into a baling zone formed within a frame. The frame is formed of a stationery front part and a rear part pivotally connected to the front part. Circumferential peripheral surface of the baling zone is lined with conveying elements, either belts, chains, drums, rollers or the like can be used. The material enters in the lower portion of the front part through an opening between two adjacent conveying elements. As it is carried along by the conveying elements, the material is turned over on itself gradually producing a round bale limited in size by the circumferential periphery of the baling zone. As the zone becomes filled, the conveying elements compress the material, wherein the inner layers fold together in a stellate manner. When the bale is completed the rear part pivots away from the front part to discharge the bale.

  • Patent number: 3938652
    Abstract: The invention relates to a feeder rake for the feeding of cut material into the baling chamber of agricultural pick-up and other balers, which is arranged to be driven by a steadily rotating crank and is guided by a swinging rod, which is connected by a link and by a guide arm with two spaced pivot bearings of the tine carrier of the feeder rake, and the guide arm has an overload protection device, upon whose actuation the feeder rake is folded back into a position in which it cannot continue feeding and, when it is freed of its load, it is erected again automatically moving out of the above-mentioned inoperative position into its operating position.
