Abstract: An agricultural machine includes a pick-up device with teeth and points, and a guiding device with a lower front end, a rear part and an intermediate part situated above the pick-up device and movable relative to the latter about a rotation center, via a displacement device movable in a first, respectively a second position and including first and second connecting devices which enable the guiding device to pivot about a first, respectively a second rotation center. The first and second connecting devices are geometrically and/or elastically configured so that in the first position, the lower front end is greatly raised above the ground and the intermediate part is brought close to the points, and that in the second position the lower front end is brought greatly close to the ground and the intermediate part and the rear part are distanced from the points.

Abstract: A strap feed assembly for a strapping machine reduces wear on the pinch and drive wheels of feed head components by creating a gap between the pinch and drive wheels while using a cam and an engagement surface to grip the strap during a cut-and-seal phase of a strapping cycle. In the strap feed assembly, a rocker arm has an engagement surface and a pivot axis parallel to both the axis of rotation of the pinch wheel and the axis of rotation of the drive wheel. An eccentric cam, driven by a cam motor, is engageable with the engagement surface of the rocker to move the pinch wheel into and out of engagement with the drive wheel. Thus, the pinch and drive wheels are configured to grip the strap during a strap feed phase, while the cam and the engagement surface grip the strap during the cut-and-seal phase.

Abstract: A round bale wrapping mechanism that employs a second roll of wrapping material that is mounted adjacent an active roll. The second roll is powered by an electric clutch that allows a belt drive connected between the first roll and the second roll to rotate the second roll of wrapping material. The wrapping material on the second roll thus feeds onto the wrapping material being fed from the active roll and if fed through the wrapping mechanism onto the bale before the active roll is exhausted of wrapping material.

Abstract: The invention concerns a method and apparatus for fine-adjustment of moving part sequences in big square balers and, in particular, for adjusting the insertion point of the needle bar and the timing of the feeding mechanism for the baling material. The fine-adjustment is accomplished by pivoting an angle adjustment mechanism, which is jointly pivotable with an intermediate drive shaft, at a maximum pivot angle of 10 degrees, but preferably 2 to 3 degrees in either forward or backward pivot directions.

Abstract: A drive and bearing device for a binding station for finished bales predominantly in waste bale presses with a horizontally acting press plate, wherein several twisting wheels provided with a radial slot for receiving the binding wire are mounted in a support and are temporarily rotated by a common drive unit for the purpose of twisting the wire. The wheels supporting the slotted twisting disks have a plurality of arms or bearing points which extend outwardly in a star-shaped manner, wherein on the free end of each arm or bearing point is mounted a roller which is freely rotatable about an axis extending perpendicularly of the wheel plane. For each wheel with the star-shaped arms is provided in the same horizontal plane a drive wheel with arc-shaped recesses at the outer circumference thereof, wherein the recesses correspond in a positively engaging manner with the rollers.

Abstract: A baler has a frame, a shaft extending on the frame along and rotatable about an axis, and a knotter having a sleeve-like hub rotationally fixed to the shaft and of a predetermined outer diameter. A support journaled on the hub is fixed to the frame and carries movable knotting parts. A rim ring surrounding the axis is formed of a main C-shaped part having arms spaced apart by a distance greater than the hub outer diameter and a bridge part between the arms and closing the main part. The rim ring also has formations engageable with the parts for actuating same. Fasteners releasably fix the rim ring on the hub.

Abstract: An automatic baler for creating a bale of compressible material comprises a mechanism for compressing an amount of the material into a bale and moving the bale along a path past a continuous strand of wire which extends across the path to engage a front end of the bale and wrap around the bale as it moves along said path. Opposing arm elements positioned on opposite sides of the path are movable toward each other to engage the path and are operable for engaging sections of the continuous wire strand. The opposing arm elements form at least two overlapped sections of wire proximate the rear end of the bale, and a twisting mechanism with twister pinions engages the overlapped wire sections to simultaneously tie the overlapped wire sections to both secure the wire wrapped around the bale and to reform a continuous strand of wire to engage the next bale.

Abstract: In the method of reducing twine tension in a bale (1) of straw in a baler in which the straw material is pressed under a high pressure, a plurality of windings of twine (6) is looped around and ties the straw material (1) while the material is subjected to the pressure.To avoid twine bursts in the use of sisal twine instead of synthetic twine, the twine tension is reduced by moving the twine windings (6) away from the top face of the bale (1) prior to the knotting operation, and the twine windings (6) are then released after the knotting operation.

Abstract: A binding machine having a base and a binding arm pivoted to the base, for tightly binding articles to be inserted between the base and the binding arm with an adhesive tape which is fed from a tape reel to a tip portion of the binding arm, by swinging down the binding arm toward the base.
