  • Patent number: 10314238
    Abstract: A block baling press has a bale chamber and a baling ram moveable in the bale chamber in an oscillating manner to compress bale material. An end face of the baling ram facing the bale material is divided into ram segments separated from one another by needle slots. At least a first needle slot is flanked by ram segments with a profiling transverse to the first needle slot. The profiling brings about a weaker compression of the bale material in an edge region of the ram segments adjacent to the first needle slot than in a region of the ram segments spaced apart from the first needle slot. Bales are obtained in which zones of high compression and low compression alternate across the width of the bale chamber. The bales are held together by twine placed around the zones having low compression.

  • Patent number: 9179598
    Abstract: A twine retaining device for a baler includes a retaining disk, which can rotate about a shaft, and a retaining plate, which jointly delimit a retaining gap. The retaining gap is defined by a plurality of constrictions distributed along a twine strand extending through the retaining gap.

  • Patent number: 9149004
    Abstract: A method for operating a baler with a pressing chamber which serves for the pressing of a straw-like crop includes compacting the crop using an adjustable pressing pressure and binding the crop through a holding material. The pressing pressure is limited to a maximum value and controlled through a control circuit. A control circuit reference variable is a load variable of the holding material. The load variable is adjustable and is smaller than or equal to the maximum value.

  • Patent number: 8813642
    Abstract: An agricultural ram press has a bale chamber, a baling ram moveable in an oscillating manner in the bale chamber, a feed channel, a feed rake arranged in the feed channel and switchable between a gathering stroke motion which compresses crop in the feed channel and a filling stroke motion which moves the crop from the feed channel into the bale channel, and a drive for driving the feed rake and having a control rod interacting with an adjustable stop to control at least one of the motions of the feed rake.

  • Patent number: 8555780
    Abstract: A bale press includes a pressing channel in which a piston is displaceable for forming a bale from crop material supplied to the pressing channel. The bale press includes a yarn supply and a knotter device arranged at a side of the pressing channel. The knotter device has a first holder for releasably holding an end portion of a yarn, a yarn deflecting member and a knotter beak. The yarn extends between the first holder and the yarn supply across the deflecting member and a side of the bale facing away from the piston. The knotter beak ties a knot in a first stretch of the yarn extending between the first holder and the deflecting member. A second holder holds the yarn at the deflecting member in an initial phase of bale formation.
