Abstract: The present invention describes a self-propelled or pulled baler for producing bales of agriculturally-harvested crops. Harvested crops are compressed in the feeding channel before entering the actual baling chamber. For this purpose a sensor reaches into the feeding channel. Crops will be pushed against the sensor by the feed rakes. As soon as a pre-adjusted pressure can be measured at the sensor, and the baling ram has moved towards the front dead center position, the motion track of the feed rakes will be switched so the compressed crops located in the feeding channel will be fed into the baling chamber through a single loading stroke. The change of the motion track of the feed rakes dependent upon the pressure sensor has the advantage that, with each loading stroke, an equal amount of compressed crops are fed into the actual baling chamber. Thus, bales of a consistent density can be produced.

Abstract: A round baler for harvested product comprises a housing, a pressure chamber with walls limiting the pressure chamber at an end side and with driven transporting elements limiting the pressure chamber at a peripheral side and forming a harvested product inlet opening, a drivable transporting rotor arranged near the inlet opening for closing the inlet opening, and a drive provided for driving the transporting elements and the transporting rotor and formed so that during the formation of a bale the drive drives the transporting roller in a form-locking manner and during a time of ejection of the bale the drive drives the transporting rotor frictionally.

Abstract: The shaping machine for circular bales of crop material has straps (belts) (12) continuously passing around a plurality of rollers (2 to 11) in a movable housing (1, 1a) which can be tilted open, forming and defining a coiling chamber (13) and having a crop material inlet (14) for the retrieved and conveyed crop material (15) between two lower rollers (2, 3) disposed at a distance from each other. A rotor (17) is disposed in the crop material inlet (14), which conveys the crop material (15) into the coiling chamber (13) while compressing the crop material, and closes off the inlet (14) at the bottom.

Abstract: A round-bale press for stalk-shaped crops has a pick-up and a press space which, on its circumference, is limited downwards by a rearwardly conveying ground arrangement, rearwards by the upwardly travelling front strand of a press-band arrangement, and forwards by a downwardly travelling movable wall arrangement. A transverse roller is provided which is movable and by which the front strand can be pressed forwards at the start of formation of a bale.

Abstract: A method of producing bales of agricultural products includes wrapping a bale with a wrapping material, discharging the fully wrapped bale from the press, and forming a new bale, with an intermediate storage of the product in the press retained as short as possible by overlapping of some of the method steps, so that the time required from the beginning of wrapping of a finished bale to the beginning of forming a new bale is very short.

Abstract: A large baling press for forming round bales has a pressing chamber which peripherally is limited by winding elements driven via cranks connected by connecting members, and mass compensating elements are connected with driving elements for the connecting members and cranks.

Abstract: A large baling press has a pressing chamber for forming bales, a device for supplying a web material for wrapping the bales, and a brake which acts on the wrapping material supply device so that in the beginning of wrapping the braking force is smaller than during the subsequent complete wrapping.

Abstract: A baling press for agricultural products has a pressing chamber limited by a plurality of winding rollers, and a device for wrapping a finished bale with a wrapping material, which is provied for its threading into the pressing chamber with guiding elements between wrapping material drawing rollers and the pressing chamber.

Abstract: A large baling press for agricultural products has a plurality of driven winding elements, a housing, a web roller with supply of web material to wrap finished bales, a container for receiving the web rollers so that the web roller is in contact with the container in at least two points, and a braking element for braking the web roller so that with decreasing diameter of the web roller it is pressed with increasing pressing force, wherein the braking element is formed as a braking rod abutting against the web roller, and a spring is provided for urging of the braking rod against the web roller.

Abstract: A round baling press for agricultural stalk products has a pressing chamber limited by a stationary front housing part and a movable rear housing part which is turnable for discharge of a finished bale about a horizontal axis and is provided with a sensing device which senses whether the turning region of the rear housing part is free of bale after its discharge to prevent turning of the rear housing part when the bale is still in its turning region.

Abstract: A large baling press has a pressing chamber peripherally limited by driven winding elements which simultaneously form an inlet opening, and a product supply passage which is limited from below by a prong drum unit and from above by a holding down rack, wherein the rack is oscillatingly moveable in a traveling or product flowing direction.

Abstract: A baler for forming round roll bales of agricultural products includes a baling chamber in which a plurality of bale-forming rotatable rolls form a bale which is wrapped with a binding tape supplied into the baling chamber from the tape supply roll positioned outside and above the baling chamber. The baling chamber is formed by two portions of the housing which are hinged away from each other to discharge the formed and wrapped bale from the baling chamber. A pair of tape advancing rollers receive a starting end of the tape from the supply roll and advance it into a gap between two adjacent bale-forming rolls so that the binding tape is taken along by the rotating formed bale in the baling chamber. A counter of the number of revolutions of at least one of the advancing rollers is provided, which causes cutting off a tape portion from the binding tape by a control device after the number of revolutions of the advancing roller has reached an adjusted number.

Abstract: A device for forming bales of hay, straw or similar crops includes a container in which there is yieldably mounted a holding member situated between the inlet end and the outlet end of the baling chamber of the container. The device picks crops up from the ground and advances the same into the inlet end of the baling chamber so that the crops form a bale thereat, and the holding member presses against the forming bale for the entire duration of the formation of the bale. The holding member retards the advancement of the forming bale toward the outlet end of the baling chamber and yields only after the material of the forming bale has reached a desired degree of packing. The holding member may be a flap pivoted in the container or a shield mounted on a tiltable frame for movement relative thereto and for tilting therewith.

Abstract: In a baler wherein material to be baled is displaced along a path past a plurality of needles into a baling chamber and wherein tying mechanism periodically displaces the needles in a predetermined direction across the path, a pair of shields are provided flanking each of the needles and displaceable in the same direction as the needles by links connected to the tying mechanism so as to force a way through material in the passage for the needles and thereby prevent bending of these needles. The shields are formed as circle segments pivotal about an axis immediately below the path and below the axis about which the needles are pivoted.
