    Reversing machine for hope
    The present invention relates to the reversal of vegetable stems, in particular of linen, which remain in the form of heaps on the field after being pulled out. More specifically, it is a reversing machine, driven or self-propelled.
    Linen is a fiber plant. In order to facilitate the extraction of the fibers in view of their use in the textile industry in particular, the linen stems undergo a rotation operation. For this operation, when the linen is harvested, after the stems have been pulled out, the latter must be laid on the ground in heaps, forming a continuous layer of stems that are mutually parallel and aligned perpendicular to the direction of travel of the extractor. . The heap remains on the field for a sufficient time for the micro-organisms present in the soil to biodegrade the pectin binder that holds the fibers together. When the degradation is sufficiently advanced, the linen is gathered to be scammed; in other words, it undergoes treatment at an industrial site for the extraction of the fibers and their cleaning with a view to their use in the textile industry.
    The biological degradation depends on the humidity conditions and the number of hours of sunshine to which the stems are exposed. Of course, these conditions can vary depending on whether the part of the stem faces the soil or the sky. Therefore, an operation takes place during the rotting process in which the hopes in the field are reversed.
    This so-called reversing operation is carried out with a machine, self-propelled or driven, which comprises gathering means which can lift the pile as a continuous layer of the ground, reversing means which can turn over the gathered layer and spreading means which can spread the layer thus reversed over the ground.
    Such a machine is described, for example, in document FR.2.484.768. In this document, the gathering means comprise a device, generally referred to as a pick-up, which is a kind of cylinder, equipped with retractable metal fingers that are in an outward position, directed towards the bottom, to gather the stems, and then at the following half turn in a retracted position to cause the stems thus collected to be picked up, still as a layer, by the reversing means. In order to allow the stems to come off the ground well and to be able to gather them properly, the pick-up rotates in the opposite direction to the wheels of the machine and about 25% faster than the latter. There are also other collection means other than the pick-up, for example as described in document FR.2.864.425.
    The reversing means generally comprise a crossed belt with pick hammers, the intersection of this belt making it possible to describe the heap by describing a half-spiral so that the heap is reversed such that the stems that were first on top of the heap are now at the bottom and vice versa. This belt with pick hammers is clamped between a front cylinder and a rear cylinder, whereby the cylinder can be coupled to the pick-up as described in document FR.2.484.768 or more generally to the gathering means as in document FR.2.653.295. However, the front cylinder can also be separate from the gathering means as in document FR.2.864.425.
    The spreading means generally comprise a set of two parallel belts with pick-hammers which ensure that the inverted heap is removed from the reversing means and transferred to the bottom. During this transfer, the heap is supported by guide means, for example a plate in document FR.2.653.295, wherein the stems are driven by the pick-hammers carried by the side belts and which penetrate in the heap towards the heads and the feet of the stems, so that the heap is optimally spread on the soil.
    When the machine is not in operation but has to move in particular over the road, the collection means must necessarily be raised above the ground. In the known machines this raising takes place by turning the gathering means and the reversing means, wherein a horizontal axis of rotation which makes this raising possible is located in a zone close to the rear cylinder on which the crossed belt is tensioned; this cylinder is generally coaxial with the cylinders on which the two side belts of the spreading means are tensioned.
    The first object of the present invention is to provide a machine as described above, the lifting technique of which differs from the known technique.
    It is a machine, self-propelled or driven, for reversing at least one heap, of the type comprising: a) gathering means that can lift the heap from the bottom in the form of a continuous layer, b) reversing means that the gathered layer, and c) spreading means which can spread the inverted layer over the bottom, all operations being performed continuously during the progress of the machine.
    Typically, the gathering means, the reversing means, and the spreading means form a one-piece assembly according to the present invention. Moreover, the machine comprises first turning means of the aforementioned whole which follow a horizontal axis, in particular for lifting it in the non-active position and for following the bottom relief in the active position.
    In contrast to the prior art cited above, the spreading means are therefore not fixed but are made to rotate about a horizontal axis, together with the gathering means and the reversing means, all of these means forming a coherent, non-deformable whole.
    The reversing of the heaps can be done with a machine that reverses one heap at a time.
    To shorten the time needed to turn the heaps around, machines were proposed that can reverse two heaps at the same time. Such a machine, as described, for example, in document FR.2.653.295, comprises on either side of the central plane, with a gap corresponding to the distance between two heaps on the field, two devices which in each case comprise the successive gathering means, reversing means and spreading means. as described above. These two devices are separate from each other. The use of such machines is associated with a specific difficulty in that two adjacent heaps in a field are not always exactly parallel, such that their spacing is not always the same. To circumvent this problem, the machine was arranged so that one of the two reversing devices can be moved laterally by the driver while the other remains fixed. The operator blocks the movement of the machine in the direction of a first heap that was inverted by the fixed reversing device and controls the lateral movement of the second device according to the positioning of the second heap. This lateral displacement of the second device is obtained by means of an angular rotation along a vertical axis of the collecting means and the reversing means. In a known manner, this vertical axis of rotation is usually situated at the point where the heap is passed between the reversing means and the spreading means, in particular at the level of the passage between the crossed reversing belt and the rear spreading belts. In this way the spreading means remain fixed, so that they do not fall back at the moment when one starts to spread the hope on the ground.
    According to another object of the invention, a machine is provided, self-pulling or driven, for reversing two heaps comprising two devices with gathering means, reversing means and spreading means, one being fixed and the other being movable in an angle and laterally. Typically, each device forms a coherent whole. Moreover, the machine comprises first turning means for the two aforementioned units along a horizontal axis, in particular for lifting them in the non-active position and for following the ground relief in the active position. Finally, the second whole comprises second rotating means for the whole according to a vertical axis with which the gathering means of the second pile can be adjusted according to the location of the pile on the bottom relative to the first pile, wherein said second whole can optionally be moved laterally to control the spacing between the spreading means of the second whole and the first whole, whereby the spacing between the first and second heaps can be defined during the spreading thereof.
    The pivot axes of the first and second pivotal means are preferably placed at the rear of the machine, predominantly at the level of the exit of the spreading means, or also predominantly at the level of the exit of the spreading means and slightly inclined forward with respect to the latter in a vertical plane that runs close to the outlet of the spreading means.
    According to an embodiment, for a machine comprising one or two of the aforementioned assemblies, wherein the spreading means comprise one or preferably two parallel belts with pick-hammers, tensioned between the front and rear wheels which are rotationally driven, the horizontal axis of rotation of the first turning means extends in a vertical plane that runs along the axis of the or the rear wheels of the spreading means.
    The horizontal axis of rotation of said first turning means in this case preferably largely coincides with the axis of the or the rear wheels of the spreading means.
    The advantage of these special features lies in the fact that the rotational movements necessary for lifting the two assemblies do not cause relative movement of the rear wheels of the spreading means.
    According to a second embodiment, for a machine comprising one or two of the aforementioned assemblies, wherein the spreading means comprise one or preferably two parallel belts with pinch hammers tensioned between the front and rear wheels that are rotatably driven, the horizontal axis of rotation of the first turning means are positioned at the height of the axis of the or the rear wheels of the spreading means, and shifted forward with respect to the axis of the or the rear wheels, preferably at the intersection of a vertical plane and a horizontal plane close to the axle of the or the rear wheels of the spreading means runs. According to this specific arrangement, the rotational movements required to illuminate the two assemblies considerably limit the relative movements of the rear wheels of the spreading means. The advantage of these specific arrangements lies in the fact that, in the event of a malfunction in the machine, it is possible to pivot the reversing means and the spreading means on the aforesaid units, whereby said spreading means can rotate, in particular gaining access to the inverted linen stems in the case of a clogging of the machine at the level of the spreading means, which can lead to interruptions in the layer of mounds.
    According to an embodiment of a machine comprising a first fixed assembly and a second assembly that can be moved at an angle or laterally with respect to the first assembly, wherein the spreading means comprise two parallel belts with pinch hammers tightened between the front and rear rotating driven wheels, the vertical axis of rotation of the second rotary means of the movable assembly is positioned centrally between the two straps of the spreading means at the level of the horizontal axis of rotation of the first rotary means. The rotational movements required for the lateral displacement of the second whole therefore only lead to very limited movements of the rear wheels that support the belts of the spreading means.
    According to an embodiment variant, the collecting means, the reversing means and the spreading means of a certain whole are driven by a single drive means.
    The present invention will be better understood upon reading the following description of a preferred example of an embodiment method of a heap reversing machine, illustrated with reference to the accompanying drawing, in which: Figures 1 to 4 are schematic representations of a machine according to the existing state of the art, wherein figure 1 shows a machine in top view, the reversing means of which are fixedly fixed laterally; Figures 2 and 3 are a side view of the machine with the reversing means in the active position (Figure 2) and in the raised position (Figure 3), and Figure 4 shows a machine whose reversing means are movable laterally;

    For simplification, the self-pulling or driven machine for turning over heaps will hereinafter be referred to as the turning machine.
    Referring to Figures 1 to 4, a reversing machine 1 with a known structure successively comprises, from front to back, gathering means 2 which lift the continuous layer 4 of stems forming the heap of soil 3, reversing means 5 capable of reversing said layer 4 and spreading means 6 which can spread the layer 4 'thus inverted over the bottom 3.
    In the example shown, the collecting means 2 comprise a pick-up 7 equipped with retractable metal fingers 8. The pick-up 7 rotates per se in the direction of the arrow F, in the opposite sense of the wheels of the reversing machine, such that the metal fingers 8, when they come into contact with the layer 4, lift it and bring it to the surface thereof while rotating, as can clearly be seen in figure 2. The pick-up 7 is preceded by a wheel 9 which when the reversing machine 1 advances, presses against the outer surface of the layer 4. Thanks to this wheel 9, the distance between the pick-up 7 and the layer 4 can remain constant, regardless of the irregularities in the ground.
    In the example shown, the reversing means 5 are formed from a belt 10 which is equipped with pick hammers 11, tensioned between a front cylinder 12 and a rear cylinder 13. The front cylinder 12 cooperates with the pickup 7 such that the layer 4 is lifted by the fingers 8 of the pick-up 7, the pick-hammers 11 move on the belt 10. This belt 10 is crossed between the front cylinder 12 and the rear cylinder 13 such that the layer 4 describes a half-spiral between the two cylinders 12, 13. Thus, the stems that were initially on top of the layer 4 on the bottom 3 now lie at the bottom after turning, and vice versa. Of course, the reversing means 5 comprise mechanical elements, not shown, such as for example round irons, to support the layer 4 during its return, when it itself is no longer supported by the belt 10.
    The spreading means 6 comprise a set of two parallel belts 14, 14 'which are equipped with pick hammers 15. Each belt 14, 14' is tensioned mounted between a front cylinder or roll 16, 16 'and a rear cylinder or roll 17, 17' wherein this last cylinder is placed close to the bottom 3 so that the inverted layer 4 ', driven by the pick hammers 15 which in said layer presses towards the head and foot of the stems, is spread as close as possible to the bottom in order to avoid disturbances . Of course, the spreading means also comprise a mechanical element, in particular round irons, which can support the inverted layer 4 'during its transfer from the front cylinders 16, 16' to the rear cylinders 17, 17 '.
    The front cylinders 16, 16 'of the spreading means are placed on both sides of the rear cylinder 13 of the reversing means. In the example shown, the rear cylinder 13 on which the crossed belt 10 is tensioned and the two front cylinders 16, 16 'for mounting on the chassis of the reversing machine 1 are mounted, according to aligned transverse axes, when the gathering means and reversing means are in an active operating position as shown in Figure 2.
    When the reversing machine is no longer in an active position, in particular when it has to move over the road, the collecting means 2 including the wheel 9 are lifted above the bottom 3. This can be done by rotating the gathering means 2 and the reversing means 5 along a horizontal axis 18 which is situated in a zone close to the rear cylinder 13 for reversing. In the example shown, it concerns the transverse axis 18 for rotating said cylinder 13.
    Figure 3 shows the non-active position in which, after the aforementioned rotation, the gathering means 2 are lifted and are located at a height above the bottom surface 3.
    Figures 2 and 3 show the planes passing through the axis of rotation of the front cylinders 12 and rear cylinders 13 of the reversing means 5, respectively PO when the reversing machine 1 is in an active operating position and P1 when the reversing machine 1 is in a non-active position, after turning the gathering means 2 and the turning means 5 around the axis 18 of an angle α.
    During the transition from the active working position to the non-active position of the reversing machine 1, no change occurs in the positioning or direction of the spreading means, since these are independent of the reversing means 5 and the collecting means 2.
    On the contrary, it is precisely a feature of the present invention that the gathering means, the reversing means and the spreading means form a coherent whole, facing each other in the same place and in the same direction, irrespective of whether they are in an active working position or in a not -active position.
    The reversing machine 20 according to the invention comprises, as described above: gathering means 21, with a pick-up 23 which is equipped with collapsible metal teeth 24, as well as a front wheel 22, reversing means 25 with a crossed belt 26 which is equipped with pick-hammers 27, tensioned between a front cylinder 28 and a rear cylinder 29, and spreading means 30 with two side belts 31, 31 'equipped with pick hammers 32, said belts 31, 31' being tensioned between front cylinders 33, 33 'and rear cylinders 34, 34 ".
    According to the present invention, the three aforementioned gathering means 21, reversing means 25 and spreading means 30 form a coherent whole in one piece.
    The transition from the active working position of the reversing machine 25 (Fig. 6) to the non-active position (Fig. 7) is achieved by rotating the whole 35 around a horizontal axis of rotation 36, this axis 36 in the example shown coinciding with the axis of rotation of the two rear cylinders 34, 34 'of the spreading means 30.
    Figures 6 and 7 show the planes passing through the axis of rotation 37 of the front cylinder 28 of the reversing means 25 and the rotary axis 36 corresponding to the axis of rotation of the rear cylinders 34, 34 'of the spreading means 30 and plane P2, respectively. the active working position (figure 6) and plane P3 in the non-active position (figure 7), after turning up an angle β. The entire assembly 35 undergoes this rotation of an angle β, including the spreading means 30.
    We note that for the lifting movement of the whole 35, the horizontal axis of rotation is in a zone close to where the inverted layer 4 'is laid on the bottom. Preferably, as mentioned above, this axis of rotation 36 coincides with the axis of rotation of the rear cylinders 34, 34 'on which the side spreading belts 31, 31' are tightened, such that there is no relative movement of the rear cylinders 34, 34 'while lighting up. However, this is not excluded according to the present invention.
    In the foregoing we have focused on the description of the gathering means, reversing means and spreading means of a reversing machine that reverses one heap at a time.
    However, according to the current trend, a reversing machine for two heaps is proposed, in other words that two heaps can turn in one pass. The reversing machine is thus provided with two devices as described above, each comprising gathering means, reversing means and spreading means. In order to take into account that the two heaps that are processed simultaneously are not always exactly parallel to each other, the reversing machine is also equipped with means to move the devices laterally and at an angle with respect to each other.
    Figure 4 shows, for a reversing machine 1 with a known structure, a device with collecting means, reversing means and spreading means which is equipped with lateral displacement means.
    In comparison with the fixed device of figure 1, this laterally displaceable device is distinguished by the following differences.
    The gathering means 2 and reversing means 5 are mounted pivotally with respect to a vertical axis of rotation 40 which is largely located in the center of the axis of rotation of the rear cylinder 13 of the reversing means 5.
    Figure 4 shows the extreme positions of the planes P4 and P5 passing through this axis of rotation 40 and through the center of the axis of rotation of the front cylinder 12, the maximum lateral displacement power of an angle Y being demonstrated. The driver of the reversing machine 1 can thus adjust the positioning of the front wheel and of the collecting means according to the variation in the distance between the two heaps. The crossed belt 10 is driven by a first motor 41, while the two rear spreading belts 14, 14 'are driven by a second motor 42. In the example shown, the two rear belts 14, 14' are on a single rear cylinder 17 mounted by said second motor 42.
    Apart from the fact that it is necessary to use two motors 41, 42 respectively for driving the gathering means and the reversing means for the first and the spreading means for the second, both motors 41, 42 must be perfectly synchronized with the progress to avoid risks of variations in the thickness of the layer during the transition of this layer from the reversing means to the spreading means.
    Moreover, as becomes apparent with reference to Fig. 4, when the reversing means pivot at an angle about the axis 40, angular displacement of the stems of the layer occurs in the same way when it is moved by the straps 14, 14 'of the spreading means. included. This allows the stems to accumulate locally on one of the belts 14, 14 'in the transition zone between the reversing means and the spreading means - an accumulation that can form an insurmountable obstacle.
    All of these disadvantages are overcome by the implementation of the present invention. As shown in Figure 8, the one-piece assembly 35 consisting of the gathering means 21, the reversing means 25 and the spreading means 30 is mounted rotatingly relative to a vertical axis 43 located at the rear of the reversing machine 20, usually at the exit location of the spreading means 30 to achieve the intended lateral displacement.
    In the illustrated example of Figure 8, this axis of rotation 43 is placed centrally between the two belts 31, 31 'of the spreading means, at the level of the axis of rotation of the rear cylinders 34, 34'.
    This axis of rotation 43 passes through the center plane of the front cylinders 28 and rear cylinders 29 of the reversing means 25.
    Figure 8 shows the median planes P6 and P7 in question, in their extreme position during the angular rotation δ of the whole 35 with respect to the vertical axis 43.
    We note that, because the vertical axis of rotation 43 is at the rear of the reversing machine, the angle δ required to obtain a certain spacing for the gathering means 21 is smaller than the angle γ that would have been necessary in a reversing machine according to a known structure as shown in Figure 4.
    The crossed belt 26 and the two rear belts 31, 31 'can otherwise be driven by the same motor 44, insofar as the rear cylinders 29 of the reversing means 25 and the front cylinders 33, 33' of the spreading means 30 can be mounted on the same rotation spindle as is the case when the device is fixed with the collecting means, the reversing means and the spreading means.
    Figures 9 to 11 show a design variant of the reversing machine according to the present invention. This reversing machine 45 comprises means similar to those described above, in particular: - gathering means 46 with a pick-up 47 equipped with collapsible metal teeth 48, as well as a front wheel 49, - reversing means 50 with a crossed belt 51 which is equipped with pick hammers 52, tensioned between a front cylinder 53 and a rear cylinder 54, and spreading means 55 with two parallel side straps 56, 56 ', equipped with pick hammers 57, which are between the front cylinders 58, 58' and the rear cylinders 59, 59 'are tense.
    According to the present invention, the three aforementioned gathering means 46, reversing means 50 and spreading means 55 form a coherent whole 60 in one piece.
    The transition from the active working position of the reversing machine 45 (Fig. 9) to the non-active position (Fig. 10) is achieved thanks to a rotation of the whole 60 about a horizontal axis of rotation 61. This axis of rotation 61 is usually located at the intersection of an vertical plane P8 with a horizontal plane P9 running close to the axis of rotation 63 of the rear cylinders 59, 59 'of the spreading means 55. This horizontal axis of rotation 61 is therefore located at the rear of the machine 45, usually at the level of the outlet of the spreading means 55 and shifted forward with respect to the latter. This axis of rotation 61 is parallel to the axis of rotation 63 of the rear cylinders 59, 59 'of the spreading means 55.
    Figures 9 and 10 show the planes passing through the axis of rotation 64 of the front cylinder 53 of the reversing means 50 and the axis of rotation 63 of the two rear cylinders 59, 59 'of the spreading means 55, respectively the plane P10 in active working position ( figure 9), according to which plane P10 coincides more or less with the horizontal plane P9 according to the unevenness in the ground, and the plane P1 in the inactive position (figure 10) after turning up an angle Θ about an axis 61 The assembly 60 thus undergoes this angular rotation Θ with respect to the shaft 61, including the spreading means 55.
    According to this design, the rear cylinders 59, 59 'undergo relative downward movement during lifting of the collection means 46; however, the positioning of the axis of rotation 61 in a zone close to the exit of the spreading means 55, where the inverted layer 4 'is laid on the bottom, limits this relative movement downwards. This relative movement downwards therefore has no effect whatsoever during the movement of the machine on the road.
    The turning machine 45 is preferably equipped with two assemblies 60 as described above, which can turn two heaps during the same passage of the machine. As shown in Figure 11, the assembly 60 is mounted pivotally with respect to a vertical axis 65 defined by the intersection of the vertical plane P8 passing through the horizontal axis 61, in other words close to the axis of rotation 63 of the rear cylinders 59, 59 'of the spreading means 55, and of the middle vertical plane P12 between the two belts 56, 56'. For example, the assembly 60 rotatably mounted along the vertical axis 65 can be moved at an angle to the second assembly, not shown in Figure 11, said assembly 60 reaching two extreme positions corresponding to the center planes P12 and P13. in Figure 11 during an angular rotation λ of the aforementioned whole 60.
    Like the reversing machine 20 according to the invention, shown in Figs. 6 to 8, the placement of the vertical axis of rotation 65 close to the rear of the spreading means 55 requires an angle of rotation λ which is substantially identical to the angle δ in order to have a given spacing for the gathering means 46 wherein this angle λ is smaller than the angle γ that was required in a reversing machine with a known structure, as shown in Figure 4. This second design method for the reversing machine 45 shown in Figures 9 to 11 offers other advantages which become clear.
    According to the design shown in Figs. 9 to 11, at least one of the two assemblies 60 of the reversing machine 45 is slidably mounted along a horizontal axis, which preferably coincides with the horizontal axis of rotation 61 as shown in Fig. 11. The assembly 60 is slidably mounted is, in particular, the whole that can be moved at an angle with respect to the other whole 60. Thanks to this sliding assembly, the equipped whole of said assembly can move laterally with respect to the other whole along the horizontal axis 61. Thanks to this In a sliding assembly, the two assemblies 60 of the reversing machine 45 can be brought together, in particular in non-active mode, which complies with road traffic regulations, which impose a maximum width for the moving machine. The two assemblies 60, on the other hand, can be spaced apart and so controlled, particularly in active mode, that their spacing is ideally matched to that of the two adjacent heaps which must be simultaneously inverted by the machine. The spacing between the two assemblies 60 is then adjusted by means of the angle adjustment according to the vertical axis of rotation 65 depending on the variations in the spacing between the two reversible heaps.
    The sliding assembly is also preferably used in the design method of the reversing machine 20 illustrated in Figures 6 to 8. In that case, the sliding assembly runs along a horizontal axis, which preferably coincides with the horizontal axis of rotation 36 of the assembly 35, which can be moved at an angle along the vertical axis of rotation 43 with respect to the second assembly 35. Thus, one of the assemblies 35 in one corner and laterally displaced with respect to the other assembly 35.
    The crossed belt 51 and the two rear belts 56, 56 'can moreover be driven by the same motor 80, provided that the front cylinders 58, 58' of the spreading means 55 are mounted on the same axis of rotation as the rear cylinder 54 of the reversing means 50. The gathering means 6, the reversing means 50 and the spreading means 55 are thus driven by a single motor 80.
    As shown in Figs. 9 and 10, the spreading means 55 are rotatably mounted with respect to the reversing means 50 along the axis of rotation 62 of the rear cylinder 54, the rotation downwards of the spreading means 55 with respect to the reversing means 50 being limited in the position illustrated in Fig. 9, for example by means of a stopper, such that an angular positioning is guaranteed between the spreading means 55 and the reversing means 50, both in active mode (Fig. 9) and in non-active mode (Fig. 10). This rotation is only used in the event of a malfunction of the installation; with this the spreading means 55 can be tilted upwards with respect to the rest of the whole 60 which, in normal use mode, forms a one-piece whole, whereby the tilting makes it possible to loosen linen stems when the machine is clogged, which would can lead to interruptions in the layer when it is inverted and then laid down at the exit of the spreading means 55.
    Figure 12 shows an example of a connection 67 for the assembly of the assembly 35, 60 on the reversing machine 20, 45 which allows the use of the horizontal axis of rotation 36, 61, the vertical axis 43, 65, and the sliding assembly with which the lateral displacement of the second whole 35, 60 of the reversing machine 20, 45 can be guaranteed. This connection 67 is usable for both the reversing machine 20 illustrated in Figs. 6 to 8 and for the reversing machine 45 illustrated in Figs. 9 to 11. This connection 67 consists of a carrying head 68 which is connected to the chassis 69 of the reversing machine 20, 45 said support head 68 receiving an intermediate support element 70 mounted via a spindle connection with respect to said head 68 along the vertical axis of rotation 43, 65. This intermediate support element 70 receives a spindle 71 which is connected to the one-piece unit 35, 60 of the reversing machine 20, 45. The spindle 71 is pivotally mounted with respect to the intermediate support element 70 along the horizontal axis of rotation 36, 61, said spindle 71 being able to slide with respect to the intermediate support element 70 along this horizontal axis of rotation 36, 61 about to allow lateral displacement of the whole 35, 60 with respect to the chassis 69. Thanks to this connection 67, the angular displacement of the spindle 71, and thus of the whole 60, can be limited during the rotation of the intermediate support element 70 with respect to the head 68, as a result of which the two extreme central surfaces P6 and P7, illustrated in Figure 8, can be achieved during an angular rotation ζ, or the two extreme middle planes P12 and P13, illustrated in figure 11, during the rotation of an angle λ. To this end, the spindle 71 is stopped against the sides 72, 73 of the head 68, thereby limiting the angular spring height of the arms 71.
