    The invention relates to a discharge device for an agricultural forage harvester and a forage harvester equipped therewith.
    State of the art
    Forage harvesters are harvesting machines that pick up crops from the ground, chop them and deposit them on a storage area of a transport vehicle traveling alongside or pulled by the forage harvester using a discharge device. In order to be able to fill the transport vehicle in a controlled manner, the direction of ejection can be changed by rotating the discharge device about a vertical axis. The height of the outlet-side end of the discharge device can also be adjusted in some embodiments in that the discharge device can be pivoted about a horizontal axis. In addition, an adjustable flap for specifying the ejection direction is provided at the outlet end of the discharge device. Such a forage harvester is disclosed, for example, in DE 101 19 279 A1.
    With relatively wide headers (maize header with eight or ten or more rows of working width) or when chopping on a slope, it sometimes happens that the optimal distance from the transport vehicle traveling alongside cannot be maintained. The distance between the forage harvester and the transport vehicle is often too great, so that the transport vehicle is only filled on one side. This can lead to wasted time in the chop chain if the transport vehicle has to be changed too early because it cannot be loaded further. In addition, when placing the chopped goods on the transport vehicle, it can be strong
    BE2018 / 0096
    Cross winds are lost if the flap of the discharge device is too far away from the trailer.
    To solve these problems, fixed extension elements are known which can be attached to the end of the discharge device or can be inserted in the middle thereof (DE 196 41 211 Al). However, they have the disadvantage that they tend to be disruptive in many other operating conditions in which the transport vehicle would drive closer to the forage harvester without them.
    Furthermore, it was proposed to assemble the discharge device from a first element connected to the forage harvester and a second element which can be displaced with respect to the first element (DE 102 11 706 A1). The discharge device is therefore telescopic in itself and thus variable in length to adapt to harvesting attachments of different widths. A single hydraulic cylinder shown in the figures or a hydraulic motor or electric motor mentioned in the description serves to adjust the second element relative to the first element. A disadvantage of the hydraulic cylinder is that it has to cover the entire adjustment path of the second element, so that it has to be very long and costly and difficult. What the connection of an electric or hydraulic motor to the discharge device can look like is not described in detail.
    Length-adjustable discharge devices have also been used on combine harvesters, for which purpose a conveyor screw (cf. JP 2003 125 639 Al), which is adjustable in length and made of flexible material by means of a hydraulic cylinder, or a conveyor belt (see EP 2 377 784 Al), the outer part of which is used a chain is adjusted, which is fixed to the movable, outer part and cooperates with a motor-driven pinion, which is supported on the inner part. The latter arrangement with the conveyor belt can be used on a combine harvester in which the crop is conveyed at a relatively low speed, but is not suitable for a forage harvester in which the crop is harvested
    BE2018 / 0096 is delivered by a conveyor into the discharge chute at a speed in the order of 100 km / h.
    task
    The problem on which the invention is based is seen in providing an improved discharge device for a forage harvester in which the disadvantages mentioned do not occur or occur to a reduced extent.
    According to the invention, this problem is solved by the teaching of claims 1, 10 and 11, features which are listed in the further claims which further develop the solution in an advantageous manner.
    A discharge device of an agricultural forage harvester, by means of which the crop material discharged from a conveying device of the forage harvester can be transported onto a transport vehicle, comprises a first, hollow element connected to the forage harvester and a second, hollow element, which during operation of the forage harvester or in a state opposite to it first element is displaceable by a power-operated adjustment drive. The adjustment drive provides a rotational movement. An elongated transmission element is coupled to the adjustment drive and generates the linear or linear movement of the second element, which takes place along a curved path.
    In other words, the rotary movement of the adjustment drive is converted into a linear adjustment movement of an elongate transmission element and this linear movement is used to adjust the second element along a straight or curved path. In this way, the adjustment drive itself does not have to accomplish the full adjustment path of the second element, as is the case in the prior art
    BE2018 / 0096 provided hydraulic cylinder is required. In order to avoid tilting of the second element, an adjustment drive and a transmission element can be present on each side of the discharge device, or a single, for example centrally arranged adjustment drive can cooperate with transmission elements on both sides. In the case of an adjustment drive coupled to the first element, the transmission element can act on the second element and in the case of an adjustment drive coupled to the second element, the transmission element can be coupled to the first element in order to displace the second element with respect to the first element.
    The conversion of the rotary movement of the adjustment drive into the linear or along an arcuate path of the transfer element could be carried out, for example, by means of a threaded spindle known per se (cf. DE 199 31 844 A1) or a worm drive, or it can be done by means of a drive wheel connected to it Interaction with the transmission element takes place.
    The elongate transmission element can be a flexible traction means, e.g. a rope, a chain or a toothed belt, which extends in particular between two or more deflection rollers, of which one (or a further roller which interacts with the traction means) serves as a drive wheel and can be driven by the adjusting drive, and the first or second element with a bracket attached to the traction device is coupled.
    In another embodiment, the elongate transmission element is a particularly straight or curved toothed rack and the drive wheel is a pinion or worm wheel that cooperates with it.
    The transmission element can be connected to the first element or second element and the adjustment drive can be supported on the second or first element. It would also be conceivable that
    BE2018 / 0096
    Support adjustment drive on the first element or second element and to couple it by means of a transmission mechanism to the drive wheel supported on the second or first element and interacting with the transmission element.
    The elongated transmission element can be attached to the side of the discharge device and / or to its top or bottom.
    The second element can contain the discharge end of the discharge device. It would also be conceivable that the discharge device comprises a third element, which contains the outlet-side end of the discharge device and can be displaced with respect to the second element by the adjustment drive or a further adjustment drive.
    A guide and a holder supported on the guide are preferably provided, which can be moved relative to the guide by the transmission element. The guide and the holder slidably support the second element on the first element, it being optional whether the holder is attached to the first or second element and the guide is attached to the second or first element. It is also conceivable that more than one holder per guide are attached in series or with more than one guide per side connected in parallel, which increases the stability of the mechanism.
    The second element can be located, in particular in the retracted state, between the first element and the transmission element and / or the guide, or the transmission element and / or the guide is or are located, in particular in the retracted state, between the first and second elements. Accordingly, the second (or possibly third) element preferably encloses the preceding element from the outside, as a result of which the crop flow is not disturbed. It is also conceivable that the downstream element (s) within the previous one
    BE2018 / 0096
    Elements are attached, which in this case could have a complicated crank shape or the resulting abutting edge could be covered by a baffle so as not to adversely affect the crop flow.
    The invention can in principle be used on any harvesting machine with discharge devices, for. B. Combines. However, it can be particularly useful for forage harvesters, since a transport vehicle is filled there during the entire harvesting process. In addition, the discharge device can be extended in a relatively simple manner, since no conveyor, such as is located in the unloading tube of a combine harvester, is provided in the discharge device.
    According to a second aspect of the invention, it is provided that the adjustment drive comprises a linear actuator which comprises a plurality of chambers whose volume can be changed by a pressure medium or a hydraulic or pneumatic muscle and / or is coupled to the first or second element by a transmission gear.
    The adjustment drive can be steplessly controlled by means of suitable input devices from the operator's workplace by manual inputs or in fixed or changeable steps. The input devices can include switches in the multifunction handle, switches in the control console or a foot switch on the cabin floor. On the other hand, sensors can also be used that detect the position of a transport vehicle and automatically control the adjustment drive in such a way that the crop is deposited at the desired location. The sensors can optically detect the transport vehicle and control the adjustment drive using image processing software. Optical or acoustic (e.g. with ultrasound) or electromagnetic waves, such as radar, can also be used to measure distances. In another embodiment, the harvesting machine and the transport vehicle each have one
    BE2018 / 0096
    Position sensor on, e.g. B. a GPS receiver whose position signals are used to automatically control the adjustment drive.

    A harvesting machine 10 shown in FIG. 1 in the manner of a self-propelled forage harvester is built on a frame 12 which is carried by front and rear wheels 14 and 16. The harvesting machine 10 is operated from a driver's cab 18, from which a crop pick-up device 20 can be viewed. By means of the crop pick-up device 20 picked up from the ground, z. B. corn, grass or the like is fed through a feed channel 36 with pre-compression rollers 30, 32 to a chopper drum 22, which it chops into small pieces in cooperation with a shear bar 46 and gives it to a conveyor 24. The knives of the chopper drum 22 can be sharpened by a grinding device 42. The material leaves the harvesting machine 10 to a transport vehicle traveling alongside via a discharge device 26 in the form of an ejection elbow. Between the chopper drum 22 and the conveying device 24 extends a secondary comminution device with rollers 28, 28 'through which the material to be conveyed is fed tangentially to the conveying device 24.
    The position of the components of the discharge device 26 can be changed by adjusting drives 48, 50, 58 and 68. A first adjustment drive 50 in the form of a hydraulic motor serves to rotate the discharge device 26, which is rotatably mounted on the frame 12 on a turntable about the vertical axis. The adjustment drive 50 enables the discharge device 26 to be rotated rearward into the rearward loading position shown in FIG. 1. or to spend them to the left or right of the harvester 10. A second adjustment drive 48 in the form of a hydraulic cylinder is set up to pivot the discharge device 26 about a horizontal axis 34 located at its upstream end. The second adjustment drive 48 thus defines the height of the downstream end of the discharge device 26. A third
    BE2018 / 0096
    Adjustment drive 58 in the form of a hydraulic cylinder serves to pivot an ejection flap 56 at the outlet end of a second element 54 of the discharge device 26. The adjustable ejection flap 56 makes it possible to set the angle at which the harvested material leaves the discharge device 26. The adjustment drives 48 and 58 are single-acting or double-acting hydraulic cylinders, with the self-weights of the discharge device 26 and the ejection flap 56 making the return movement possible in the case of single-acting hydraulic cylinders. The adjusting drives 48, 50, 58 and 68 can be controlled by means of an input device 98, which is located in the driver's cab 18 and, unlike shown, can be attached to a driving lever and is connected to a controller 53, which controls the adjusting drives 48, 50 , 58 and 68 controlled, usually using feedback sensors to detect the respective position of the adjustment drives.
    The discharge device 26 is constructed from a first element 52 and the second element 54. The first element 52 is attached to the frame 12 (rotatable about the vertical axis and the horizontal axis 34 on the slewing ring 50 and movable by the adjustment drives 48, 50). At the downstream end of the first element 52, the second element 54 is pushed onto the first element 52. The second element 54 is displaceable relative to the first element 52 by the fourth adjustment drive 68 in the longitudinal direction of the discharge device 26, by the distance between the outlet-side end of the second element 54 and the vertical axis of rotation of the discharge device 26 during operation or standstill or before or after to be able to vary a road transport of the harvesting machine 10. The support and mounting of the second element 54 on the first element 52 as well as the supply of the adjustment drive 58 as well as a lamp (not shown) attached to the end of the discharge device 26 can, as in DE 102 1 1 706 A1, the disclosure of which is referred to in the present documents will be included.
    BE2018 / 0096
    The first element 52 and the second element 54 are open at the bottom, since the chopped crop slides along the top of the elements 52, 54 of the discharge device 26 due to the centrifugal force. However, embodiments that are at least partially closed down would also be conceivable. The elements 52 and 54 are hollow, i.e. not provided with internals through which the crop would be actively conveyed by the discharge device 26. The crop is transported through the discharge device 26 only by the kinetic energy imparted to it by the conveying device 24.
    The fourth adjustment drive 68, which brings about the linear adjustment movement of the second element 54 with respect to the first element 52, is not designed as a linear hydraulic cylinder, but rather as a motor providing a rotational movement, in particular a hydraulic, pneumatic or electric motor. Its shaft 72 drives a first deflecting roller 60 which serves as a drive wheel (directly or via a gear which, for example, is geared up or down). A flexible traction element 64 in the form of a rope, a chain or a toothed belt or V-belt is looped around the first deflection roller 60 and a second deflection roller 62, which serves as a transmission means, around the rotary movement of the adjustment drive 68 into the desired linear or along a curved path implement the adjusting movement of the second element 54. A holder 66 is coupled to the pulling element 64 and is coupled to the second element 54 via a connecting rod 70. In another embodiment, the connecting rod 70 could also be omitted and the second element 54 could be coupled directly to the holder 66. In the embodiment according to FIG. 1, the adjusting drive 68 accordingly drives the deflection roller 60, the flexible traction means 64, the holder 66 via the shaft 72 (or another transmission element, which can be an angular gear, a pinion or a worm gear) and optionally the connecting rod 70 to the second element 54. The traction means 64 can be held on an arcuate path by central guides (not shown) or the holder 66 and / or
    BE2018 / 0096
    Connecting rod 70 are movable in the direction oriented transversely to the adjustment direction with respect to the tension element 64. In this embodiment, the deflection rollers 60, 62 are laterally attached to the first element 52 and the adjustment drive 68 is also supported on the first element 52. A further adjustment drive (not shown) is arranged on the side of the discharge device 26 which is not visible and which is coupled to the second element 54 via a mechanism which corresponds to the mechanism shown in FIG. In a further embodiment, no adjustment drive and / or only one guide can alternatively also be arranged in FIG. 1 and all other figures on the invisible side of the discharge device 26, the adjustment of the element 54 then taking place on one side.
    The embodiment according to FIG. 2 is shown in an exploded view in order to make the structure easier to recognize. In this embodiment, the holder 66 is slidably mounted on a guide 78 and is pulled back and forth along the guide 78 by the traction means 64 arranged within the guide 78 and serving as a transmission means. Alternatively, the traction means 64 can also be arranged outside the guide 78. The deflection rollers 60 and 62 can, as in the embodiment according to FIG. 1, rotate about horizontal axes or about vertical axes. The second element 54 is preferably pushed onto the first element 52 on the outside of the element 52 and connected to the holder 66 at fastening points 74. It is also conceivable that more than one mountings 66 per guide 78 are arranged in series or if more than one guide 78 is connected in parallel, which increases the stability of the mechanism. If a plurality of brackets 66 are arranged one behind the other or parallel to one another (next to one another in the transverse direction of the discharge device 26), the number of fastening points 74 would also increase accordingly. It is also conceivable that more than two elements 54 are arranged one behind the other in the flow direction of the material 52 and connected at the fastening points 74. The elements are
    BE2018 / 0096 preferably attached to element 52 from the outside so that the crop flow is not disturbed. It is also conceivable that the respective downstream element (s) 54 are attached within the preceding element 52, as a result of which in this case they would have to have a complicated crank shape or the resulting abutting edge would have to be covered by baffles in order not to adversely affect the crop flow.
    The guide 78 could be laterally spaced from the side walls of the elements 52, 54 and could only be connected to the first element 52 at its upstream fastening point on the first element 52, which is located on the first deflection roller 60. Following in the direction of the crop flow, the guide would accordingly be cantilevered outward from the elements 52, 54. However, an arrangement in which the guide is located between the elements 52, 54 would be preferred. The guide 78 can then be coupled to the first element 52 over its entire length.
    A further adjustment drive 68 (not shown) can be arranged on the side of the discharge device 26 which is not visible and which is coupled to the second element 54 via a mechanism which corresponds to the mechanism shown in FIG.
    The embodiment according to FIG. 3 corresponds to that according to FIG. 2, with the difference that the guide 78 is located on the top of the first and second elements 52, 54. Here, two adjustment drives 68 can be arranged laterally next to one another on the upper side of the first and second elements 52, 54 and / or a further adjustment drive 68 can be attached to the underside of the first and second elements 52, 54 and via a mechanism that corresponds to that in FIG mechanism shown may be coupled to the second element 54. The arrangement of Figure 3 is carried out analogously to that of Figure 2, but curved in a different plane.
    BE2018 / 0096
    In the embodiment according to FIGS. 4 and 5, the shaft 72 of the adjustment drive 68 is coupled (directly or via a gear) to a pinion 80 or worm wheel serving as a drive wheel, which cooperates with a rack 82 serving as a transmission means, which acts at a fastening point 86 on the second Element 54 is attached. The rack 82 is held at the top by rollers 84, which, by suitable shaping of the rollers 84 and the rack 82, also fix, stabilize and guide the latter in the lateral direction. Here the pinion 80 or worm wheel is accordingly fastened to the first element 52 and pulls or pushes the rack 82 and thus the second element 54 when the adjusting drive 68 is activated in the drawing plane of FIG. 4 to the left and right. A further adjustment drive 68 (not shown) is arranged on the side of the discharge device 26 which is not visible and which is coupled to the second element 54 via a mechanism which corresponds to the mechanism shown in FIG. The rollers 84 can be attached to a further support (not shown) which is connected to the first element 52 only in its lower region and which allows the second element to be drawn in between the rollers 84 and the first element 52. However, an arrangement in which the toothed rack 82 and the rollers 84 are located between the elements 52, 54 would be preferred. Then, rack 82 can be coupled to first element 52 over its entire length.
    The embodiment according to FIG. 6 corresponds to that according to FIGS. 4 and 5, with the difference that the toothed rack 82 is fastened to the first element 52, while the adjustment drive 68 and the pinion 80 or worm wheel coupled therewith are fastened to the second element 54. Since, in a possible embodiment, the second element 54, analogous to the embodiment according to FIG. 2, pushes between the rack 82 and the first element 52 when it is retracted, the rack 82 can also only be at the lower, in the embodiment according to FIG FIG. 6 the end drawn in on the left are connected to the first element 52 and otherwise laterally via the first and second elements 52, 54
    Protrude BE2018 / 0096. For this reason, rollers 84 attached to the first element 52 are held on the first element 52 in a vertical and lateral direction, analogously to FIG. 5. In another embodiment, the rack 82 is arranged between the first element 52 and the second element 54, as also described above with reference to FIGS. 4 and 5.
    A further adjustment drive 68 (not shown) is arranged on the side of the discharge device 26 which is not visible and which is coupled to the first element 52 via a mechanism which corresponds to the mechanism shown in FIG. In the embodiment according to FIG. 6, the rollers 84 can also be attached to a further carrier (not shown) which is connected to the first element 52 only in its lower region and the retraction of the second element between the rollers 84 and the first element 52 allows.
    The embodiment according to FIGS. 7 and 8 corresponds to that according to FIG. 6, but the adjustment drive 68 is not fastened to the second element 54 but to the first element 52 and is coupled to the pinion 80 or worm wheel via a force transmission element 90. The force transmission element 90 can be a flexible or rigid shaft or spindle or a flexible traction means (chain, rope or toothed belt) or a toothed rack. In the case of a flexible traction device, measures would still have to be taken to tension the traction device when the second element 54 moves to the left, which can be done using a free-running roller that is tensioned by a spring, or a mechanism such as this is used is used per se in telescopic cutting units (cf. EP 1 653 122 Al). In the embodiment according to FIGS. 7 and 8, the rollers 84 can also be attached to a further carrier (not shown) which is connected to the first element 52 only in its lower region and the retraction of the second element between the rollers 84 and the first Element 52 allows. A further adjustment drive 68 (not shown) can be arranged on the side of the discharge device 26 that is not visible
    BE2018 / 0096
    Mechanism, which corresponds to the mechanism shown in FIG. 7, is coupled to the first element 52. Likewise, the adjustment drive 68 can only be mounted on one side (for example on the visible side), but by means of a transmission element (not shown here), can also effect an adjustment on the non-visible side of the discharge device 26 in order to counteract tilting.
    The embodiment according to FIG. 9 uses a flexible traction means 64, in particular a rope, to adjust the second element 54, which is wound on a roller 60 which can be set in rotation by the adjustment drive 68 (not shown here). The traction means 64 is fixed at its outer end to a fastening point 90 on the second element 54 and pulls the second element 54 inward from the end position shown in FIG. 9 if necessary. The second element 54 is reset by a compression spring 92 or a gas pressure spring or a pneumatic length-adjusting element 92. A guide 78 fastened to the first element 52, which can correspond to that according to FIG. 2, defined in cooperation with one attached to the second element 54 Bracket 66 the path of the second element 54. On the invisible side of the discharge device 26, a further adjustment drive 68 (not shown) can be arranged, which is coupled to the second element 54 via a mechanism which corresponds to the mechanism shown in FIG , In the embodiment according to FIG. 9, the rope could be coupled to the elements 52, 54 by a pulley. Likewise, the adjustment drive 68 can only be mounted on one side (for example on the visible side), but by means of a transmission element (not shown here), can also effect an adjustment on the non-visible side of the discharge device 26 in order to counteract tilting. In a further embodiment (not shown here), the adjustment drive 68 can also be mounted on the second element 54.
    In the embodiment according to FIG. 10, in addition to the second element 54, a third, displaceable element 94 is provided,
    BE2018 / 0096 which defines the discharge end of the discharge device 26 with the flap 56. The second and third elements 54, 94 are adjusted by a single drive element, e.g. a pinion 80 or a worm wheel, which is coupled directly or via a force transmission element to the adjustment drive 68 and is rotatably supported on the second element 54. A first toothed rack 82 connected to the first element 52 meshes with the pinion 80 (analogous to the embodiment according to FIG. 6) and a second toothed rack 82 'connected to the third element 94 meshes from the e.g. diametrically opposite side also with the pinion 80 (analogous to the embodiment according to FIG. 4). The second and third elements 54, 94 are thus simultaneously adjusted by the pinion 80. A further adjustment drive 68 (not shown) can be arranged on the side of the discharge device 26 that is not visible, via a mechanism which corresponds to the mechanism shown in FIG. Likewise, the adjustment drive 68 can only be mounted on one side (for example on the visible side), but by means of a transmission element (not shown here), can also effect an adjustment on the non-visible side of the discharge device 26 in order to counteract tilting. In a further embodiment (not shown here), the adjustment drive 68 can also be mounted on the second element 54.
    In further embodiments (not shown), one (or more) further adjustable element 94, 94 'can also be attached to FIGS. 1, 2, 3, 4, 6, 7, 9 and 11, which is repeated by repeating the respective in the mentioned figures shown and named adjustment mechanisms is adjusted.
    In the embodiment according to FIG. 11, the second element 54 is adjusted by a linear actuator 94 in the form of a multi-stage telescopic hydraulic cylinder which is articulated at both ends at pivot points 92 on the first and second elements 52, 54. The linear actuator 94 accordingly comprises at least three tubes, two of which are telescopic, i.e. it comprises two volumes that can be changed in volume by a pressure medium (hydraulic fluid),
    BE2018 / 0096 chambers connected in series. Instead of being a hydraulic cylinder, the linear actuator 94 could also be designed as a multi-stage pneumatic cylinder. It could also be designed as a so-called hydraulic or pneumatic muscle, in which a membrane or another material expands in the circumferential direction when pressure is applied, which produces a contraction movement and a tensile force in the longitudinal direction, which leads to the displacement of the second element 54 and possibly the third Elements 94 could be used. In this case, a single muscle could be present, or several muscles could be connected in series in order to increase the adjustment path achieved. It would also be conceivable to design the linear actuator as an arrangement with one or more bellows connected spatially in series (cf. DE 10 201 1 107 580 A1). The movement of all the linear actuators mentioned can, if necessary, be increased in their stroke by means that translate the movement, such as a lever.
    It should also be noted that various modifications of the embodiments shown would be conceivable.
    Thus, in the embodiments of FIGS. 2 and 3, the flexible traction means 64, embodied as a chain or toothed belt, or a rigid toothed rack 82 could be attached to the guide 78 and the holder 66 moving along the guide 78 with a pinion 80 driven by the adjustment drive 68 or worm wheel to generate the adjustment movement.
    In the embodiment according to FIG. 10, the second element 54 could be adjusted relative to the first element 52 by a mechanism as shown in one of FIGS. 2 to 4, while the third element 94 could be adjusted by means of a mechanism according to FIGS. 6 or 7 second element 54 could be adjusted, or only a single adjustment drive is used, which acts on the first and third elements 52, 94.
    BE2018 / 0096
    In the embodiments in which a component moves relative to an elongated guide or vice versa, e.g. Like the holder 66 opposite the guide 78 in FIGS. 2 and 3 or the rack 82 relative to the rollers 84 in FIGS. 4, 6, 7 and 10, a sliding, ball or other rolling-element bearing can be used to hold the components together to be linearly displaceable and movably support the second element 54 with respect to the first element 52. Such linear ball guides can contain two elongate elements which are movable relative to one another and which are supported against one another by balls or other rotating elements such as rollers or cones. They can also be used to support the second element 54 with respect to the first element 52, irrespective of the position of the adjustment drive 68 and the power transmission to the second element 54. For this purpose, it would also be conceivable to use a roller guide, as is the case with drawers is known here. This can be equipped with smooth rollers and guides, or the rollers and guides can be toothed to match one another, which makes it possible to set the roller in rotation by the adjustment drive 68 in order to generate the adjustment movement.
    Finally, the adjustment mechanism can be sealed against environmental influences. It can be designed as a bellows or telescopic sheet metal seal or as a combination thereof, which is attached at one end to the first element 52 and the other end to the second element 54 and that shown in FIGS. 1 to 11, for generating and / or transmitting the adjustment movement serving components semicircular or rectangular or in any other shape and abuts the walls of the first or second element 52, 54. In the embodiment according to FIGS. 1 to 3, the traction means 64 could be arranged in a sandwich-like manner between two walls which lie in planes extending perpendicular to the axis of rotation of the deflecting rollers 60, 62, and enclose with its edge a slight gap with the walls, which is provided by flexible elements (Brushes, felt or similar) must be sealed
    BE2018 / 0096 can. The traction means 64 then serves at the same time to seal the deflection rollers 60, 62.
    In all of the embodiments, the drive can optionally be carried out by electrical, hydraulic, pneumatic means or a combination of two or all of the means mentioned.
