Abstract: A grinding device and a grinding method for grinding at least one knife. The grinding device includes a frame with a knife holder and a grinding unit comprising a grinding head, a grinding head holder, and a grinding head drive assembly. The grinding unit can selectively be connected with the frame or can be disconnected from the frame and can be placed on a cutting assembly with knives to be ground. In both operating modes the grinding head drive assembly rotates the grinding head and moves the rotating grinding head with respect to the grinding head holder.

Abstract: An apparatus and a method for forming and wrapping a bale in a bale forming chamber into wrapping material includes a wrapping material conveying device that conveys a web of wrapping material towards a wrapping material inlet. A severing device severs the web at a severing location. The wrapping material conveying device moves the web towards the inlet, forms a leading segment of the web, and keeps the leading segment in an intermediate web providing position between the wrapping material inlet and the severing location without moving the leading segment. For starting the wrapping procedure, the web is conveyed towards the inlet.

Abstract: A baler-wrapper combination includes a bale forming device and at least one wrapping device with a bale support. The bale support being in the bale depositing position has a lateral offset to a vertical center plane of the bale forming device and is entirely positioned on one side of the vertical plane. A bale is moved on the bale support being in the bale receiving position and is wrapped. The wrapped bale is deposited from the bale support being in the bale depositing position on the ground.

Abstract: A wrapping apparatus and A wrapping method are provide to wrap an object in a chamber into a web of wrapping material. The web is moved from a reservoir outside of the chamber. A tag applicator applies a tag on the web in an application position which is between a wrapping material reservoir and a wrapping material inlet. A tag reader monitors whether or not a tag is conveyed in the chamber along the tag reader. If no tag is detected, an alert is generated that the object is not properly wrapped.

Abstract: A bale forming apparatus including a bale forming device providing a bale forming chamber, a rotatable driving member, a shaft, and a free-wheel clutch provided between the shaft and the rotatable driving member. The shaft drives at least temporarily the rotatable driving member. The free-wheel clutch transfers a rotation of the shaft onto the driving member. The rotated driving member drives at least one part of the bale forming device. The bale forming device forms a bale in the provided bale forming chamber. At least one time the rotatable driving member is rotated with respect to the shaft. The free-wheel clutch enables this rotation of the rotatable driving member.

Abstract: A wrapping device and a web supplying method are used on board of an agricultural harvester. A supply reel with wrapping material is held between two parts of an unrolling station. A web moving member moves a web taken from this supply reel away from the unrolling station. For replacing the supply reel with a further supply reel, the further supply reel is placed on at least one supporting roller. The or every supporting roller is stationary and is positioned angularly below the unrolling station and between two unrolling station parts. The further supply reel on the supporting roller is shifted in a shifting direction towards an unrolling station part.

Abstract: A baler baling chamber has a movable chamber part pivotally mounted at a fixed chamber part. Several conveying units convey the bale along a circumferential wall. The baler can be transferred into a bale ejecting mode by pivoting the movable chamber part away from the fixed chamber part. One conveying unit is mounted at the moveable chamber part and adjacent to the fixed chamber part. In a bale forming mode, the adjacent conveying unit engages into a receiving aperture in the fixed chamber part and conveys loose material into the bailing chamber. The adjacent conveying unit can be pivoted away from the fixed chamber part and out of the receiving aperture increasing the aperture for ejecting a bale out of the bale forming chamber as the adjacent conveying unit is pivoted out of the receiving aperture.

Abstract: A feeding apparatus and a feeding method are disclosed. The apparatus and the method feed wrapping material towards an inlet of a chamber. An object in this chamber is to be wrapped with wrapping material injected into the chamber. A wrapping material supplying unit supplies wrapping material from a reservoir towards the inlet such that a loose end area is formed. A drive drives a conveying surface of a wrapping material feeding unit either in a feeding direction or in a cleaning direction. If moved in the feeding direction, the conveying surface conveys the loose end area towards the inlet. If moved in the cleaning direction, the conveying surface cleans the inlet from debris.

Abstract: A bale forming apparatus and a bale forming method form cylindrical bales. A bale forming chamber is surrounded by a bale forming mechanism. A bale is formed in this bale forming chamber. This bale is pushed onto a bale supporting construction. This bale supporting construction buffers the bale. A further bale is created in the bale forming chamber. One pushing member pushes the old bale from the bale forming chamber onto the bale supporting construction. This pushing member is connected with a holding device and performs a movement on a circular path for pushing the bale. The drive rotates the holding device around a rotating axis. A pivotal guiding member is pivoted into a guiding position and contributes to provide a bale forming chamber for the new bale.

Abstract: A grinding device and a grinding method for grinding at least one knife. The grinding device includes a frame with a knife holder and a grinding unit comprising a grinding head, a grinding head holder, and a grinding head drive assembly. The grinding unit can selectively be connected with the frame or can be disconnected from the frame and can be placed on a cutting assembly with knives to be ground. In both operating modes the grinding head drive assembly rotates the grinding head and moves the rotating grinding head with respect to the grinding head holder.

Abstract: A belt-roller arrangement with a deflecting roller and an endless flexible belt and a method for guiding such a belt over such a roller are disclosed. The roller body of the roller includes two deformable roller body segments and a rigid roller body segment part which is—in an axial direction—positioned between these two deformable segments. The belt is entirely guided over the central rigid segment part and at least partially over both deformable segments. The belt run is automatically corrected.

Abstract: A bale forming apparatus and a bale forming method are provided. A bale is formed in a bale forming chamber. A bale pushing device pushes the bale away from an outlet onto a bale supporting construction. A guiding element is pivoted into a guiding position. The guiding element in the guiding position contributes to guide a bale forming mechanism such that a bale forming device a chamber is also provided when the bale is on the bale supporting construction. A new bale is formed in the provided bale forming chamber. The bale pushing device is pivoted around the pivoting axis in a pushing direction and backwards and performs a reciprocating movement. Pivoting the bale pushing device in the pushing direction causes the guiding element to be pushed and pivoted into the guiding position.
