  • Patent number: 10244682
    Abstract: A conveyor belt has one or more conveyor belt segments made of an elastomeric material layer and a reinforcement layer of steel ropes disposed in the elastomeric material layer and oriented in a longitudinal direction of the conveyor belt segment. The conveyor belt segments each have a first segment end provided with a first transverse lock bar and a second segment end provided with a second transverse lock bar, wherein ends of the steel ropes are locked frictionally or with form fit in the first and second transverse lock bars, respectively. One or more detachable closure members couple the first and second transverse lock bars of a single one or of adjacently positioned ones of the conveyor belt segments to each other in a rigid correlation relative to each other.

  • Patent number: 8225713
    Abstract: A baling press for producing large square high-density bales has a pick-up device picking up crop, a cutting device downstream of the pick-up device, a conveying device downstream of the cutting device, and a pressing channel disposed downstream of the conveying device and receiving the crop from the conveying device. The crop is shaped to high-density bales in the pressing channel. A tying device is provided that, for ensuring a permanent cohesion of the bales and completing the bales, ties tying medium strands, connected in endless loops, in longitudinal direction of the bales about the bales. A spacing of outermost tying medium strands, disposed next to outer parallel longitudinal bale edges, relative to the outer parallel longitudinal bale edges, respectively, is at least as large as or greater than an average spacing between neighboring tying medium strands in a transverse direction transverse to the longitudinal bale edges.

  • Patent number: 7181898
    Abstract: A machine for collecting and pressing a crop to roll-shaped bales has a crop collecting device and a bale-forming device defining a winding chamber arranged downstream of the crop collecting device. At least a first and a second stationary deflection devices are provided, wherein the bale-forming device is guided about the first and second stationary deflection devices. Stationary guides are positioned between the first and second stationary deflection guides. The bale-forming device, during a first bale-forming phase, travels along a spatially determined movement path and is supported on the stationary guides. The bale-forming device is lifted off the stationary guides during a second bale-forming phase. For compressing a bale to be formed after reaching a preset bale diameter, the bale-forming device exerts on the bale to be formed in a compression phase a compression force in a direction from the exterior to the interior of the bale.

  • Patent number: 7181899
    Abstract: A machine for collecting and pressing a crop to roll-shaped bales has a crop collecting device and a bale-forming device with a winding chamber arranged downstream of the crop collecting device. The bale-forming device is guided about first and second stationary deflection devices. Guides are positioned between the first and second stationary deflection guides. During a first bale-forming phase, the bale-forming device travels along a spatially determined movement path on the guides. During a subsequent bale-forming phase, the bale-forming device is transferred to additional movement paths that are independent of the guides and are determined by the diameter of the bale. The maximum bale diameter is selectable by moveable control devices. After the bale reaches the selected maximum diameter, the bale-forming device initiates a compression phase and exerts a compression force on the bale from the exterior to the interior of the bale.

  • Patent number: 7140170
    Abstract: A device for determining and controlling a bale length on a pick-up baler for agricultural harvested material has a pick-up device, a feed channel connected to the pick-up device, and a pressing channel with pressing piston connected to the feed channel. A conveying device conveys the harvested material through the feed channel into the pressing channel. The pressing piston compacts the harvested material. A sensor detects a bale growth resulting upon compression of the harvested material during the feed stroke from the feed channel into the pressing channel. An electronic evaluation device is connected to the sensor that supplies a bale growth value to the electronic evaluation device where it is converted into an averaged operand or a statistical operand for determining a required number of feed strokes for reaching the nominal bale length. After the computed number of feed strokes is reached, the binding device is triggered for tying the finished bale.

  • Publication number: 20030101697
    Abstract: The invention concerns a bale wrapping device comprising a wrapping platform (1) on which a bale (11) is rotatable about a horizontal axis (9) and a support frame (23), which carries at least one rotating arm (17) rotatable about a vertical axis (19) by means of a rotation drive (18, 21). In order to reduce the overall height of the rotating arm drive, it is proposed according to the invention that the rotation drive (18, 21) is arranged between the upper side (A) of the support frame (23) and the under side (B) of the rotating arm (17).
