Description

Device and method for producing a flexible strand of material

The present invention relates to a device for producing a flexible material strand according to the preamble of claim 1 and a method for producing a flexible material strand according to the preamble of claim 14.

Flexible strands of material, in particular hoses filled with a bulk material or a liquid, are used in a variety of ways. For example, they can be used as hose barriers to protect against flooding, flooding and erosion. In addition, they can serve as a basis for dykes and dams, the hoses then being enclosed with earth, tarpaulins and the like. Building material. This means that military protective walls can also be erected or landscapes can be designed in a targeted manner.

Instead of filled sacks, which are mainly known from flood protection, such flexible strands of material have the advantage that there are fewer predetermined breaking points that can allow flooding to penetrate, since the strands of material have a much greater length in contrast to relatively small sacks. In addition, almost any contours can be created with such material strands because the material strands can be bent relatively freely with respect to their length.

In this context, it is already known from DE 10 2004 009 662 A1 to collect sand in a loader shovel and fill it into gathered hoses via a transport screw connected to the loader shovel. These filled hoses then form a strand of material that is immediately placed on the spot. In this way, however, only strands of material with a relatively small diameter and short length can be freely handled. For larger diameters and the associated higher weights, the output into the hose must be essentially at floor level, because otherwise the hose will automatically pull off due to its high weight. With such a storage at floor level, however, no randomly designed systems can be built with the material strands, because the wheel loaders cannot be maneuvered at will and, in particular, must have a solid base at the location of the storage. The length is in turn automatically limited by the pushed-on hose, which cannot be made available in any length. It is therefore the object of the present invention to provide a possibility for the production of flexible material strands which avoids the disadvantages of the prior art. In a preferred aspect of the invention, the material strands should in principle be endlessly producible. In a further preferred aspect, the material strands should be able to be handled freely even with large diameters of the material strands. In a further preferred aspect of the invention, the production should be possible in a scalable manner with regard to the dimensions of the material strand. In a further preferred aspect of the invention, it should be possible to lay the material strand immediately after production.

1 to 4 show the device 10 according to the invention for positioning and distributing a flexible material strand 11 (cf. FIGS. 5 and 5a).

It can be seen that the device 10 has, in addition to a device 12 for transporting the flexible material strand, a movement device 14 and means 16 for producing the flexible material strand.

The means 16 for production include a storage or supply container 18 for the material, which in the present example is sand (not shown), means 20 for producing the material strand covering 22 (cf. FIGS. 5 and 5a) and means 24 for filling of the material into the material strand sheathing 22.

Furthermore, there is a housing 26 which is arranged so as to be rotatable 27 relative to the movement device 14.

The means 20 for producing the material strand covering 22 have a store 28 for the covering material 30 to be kept in stock, a pulling shoulder (forming shoulder) 32 for the formation of the tubular material strand covering 22 and a hose forming device 34 for fixing the material strand covering 22 and stabilizing the material strand formed 11.

The inventive device 12 for transport has strand feed means 36 which are designed as a pull-off unit for the means 16 for producing the flexible material strand 11, and strand removal means 38 which are connected to one another via hinge means 40.

In the rear part of the device 10 there is a supply 41 for electricity and hydraulics for the elements of the device 10. The means 16 for producing the flexible material strand 11, the strand feed means 36 and the joint means 40 are arranged on the housing 26 so that they can be rotated together with respect to the movement device with respect to the vertical axis of rotation 27. As a result, these elements 16, 36, 40 can be aligned with the housing 26 in a horizontal plane (if the movement device 14 itself is also set up on a horizontal plane).

The joint means 40 include a vertical axis of rotation 42 and a horizontal axis of rotation 44. As a result, the strand discharge means 38 can be compared to the longitudinal extension L of the housing 26, that is to say about the axis of rotation 42 in an angular range of a = ± 30 ° (see. FIG. 3) and opposite of the horizontal H, that is to say about the axis of rotation 44 in an angular range of β = ± 15 ° (cf. FIG. 4). However, larger angular areas of, for example, a, β = ± 90 ° can also be used in each case.

With this device 10 according to the invention, a flexible material strand 11 can be produced and laid as desired in order, for example, to form the base 46 of a high water protection structure shown in FIG. 5. These flexible material strands 11 have a diameter of approx. 500 mm, for example, so that a base 46 with a height of approx. 2010 mm and a width of approx. 2750 mm with an angle of repose d = 54.7 ° can be produced, which are sufficiently dimensioned for the formation of a dike (not shown).

Due to the free rotation of the housing 26 and thus the device 12 for transporting the flexible material strand 11 with respect to the movement device 14 as well as the additional free pivotability of the strand discharge means 38 with respect to the housing 26, the movement device 14 can be moved on a solid surface while the flexible material strand is produced 11 can be freely handled and piled up to form the base 46.

Instead of the housing 26 being freely rotatable about the axis of rotation 27, however, provision could also be made for the housing 26 to be arranged rigidly with respect to the movement device 14, whereby the material strand distribution then takes place solely through the pivotability of the strand discharge means 38. This rigid training would have the advantage that then the feed container 18 would always remain in the same place, as a result of which it can be easily filled, for example by an excavator (not shown).

In order to enable the supply container 18 to be filled directly from the truck, a receiving container (not shown in FIGS. 1, 2, 3, 4 and 29, but see FIG. 30 for device 10 ') can exist in addition to the supply container 18 , which is arranged so low on the device 10 that it can easily be filled directly from the truck. Then one would provide additional transport means, for example in the form of a screw conveyor or a conveyor belt, which transfer the material from the receiving container into the feed container 18 as required.

The device 12 according to the invention for transporting the flexible material strand 11 is described in more detail below in connection with FIGS. 6 to 11.

It can be seen that the pulling unit 36 downstream of the hose forming device 34 has a frame 100 in which there is a lower conveyor belt 102 and an upper conveyor belt 104 arranged directly above it. The lower conveyor belt 102 simultaneously forms the support and a first drive means for the flexible material strand 11 to be transported. The upper conveyor belt 104 simultaneously forms the means for weighing down the flexible material strand 11 to be transported and a second drive means for the flexible material strand 11 to be transported this weighting with the upper conveyor belt 104 can be dispensed with.

The drives (not shown) of the lower conveyor belt 102 and the upper conveyor belt 104 are each electric motors which drive rollers for the conveyor belts 102, 104. These drive rollers and assigned guide rollers for the conveyor belts 102, 104 can be displaced in terms of their spacing from one another in order to be able to adjust the tension of the conveyor belts 102, 104.

Both the lower conveyor belt 102 and the upper conveyor belt 104 are arranged in a stationary manner in the frame 100. However, it can also be provided that the upper conveyor belt is displaced vertically at least on one side, preferably completely and in any orientation. is bar in order to be able to react to differences in height in the transported flexible material strand 11.

In addition, there are means 106 for the lateral guidance of the transported flexible material strand 11 in the form of a plurality of vertically aligned rollers or rollers arranged opposite one another in relation to the transported flexible material strand 11.

The pull-off unit 36, which pulls the strand of material 11 generated in the means 16 for producing the flexible material strand 11 from the tube forming device 34, ensures that the strand of material 11 produced is continuously transported away, with the strand of material 11 being compressed and shaped at the same time.

In FIG. 8 it can be seen that the strand discharge means 38 are designed as booms which have three identically designed boom modules 108, 108 ', 108 ". Each of these boom modules 108 has two lower conveyor belts 110 (see FIG. 9). between each of which there is an intermediate roller 112. In contrast to the conveyor belts 110, which can again be driven via drive rollers 114 and corresponding electric motors (not shown), the intermediate rollers 112 are freely rotatable the drive roller 114 assigned to a conveyor belt 110 and the corresponding guide roller 116 can be changed in order to be able to adjust the tension of the conveyor belts 110.

In addition, upper conveyor belts (not shown) could again exist in order to weigh down the transported flexible material strand 11.

As part of the strand discharge means 38, additional intermediate rollers 118 are arranged between each two boom modules 108. In addition, such intermediate rollers 118a, 118b also exist on the boom module 108 in the direction of the housing 26 and on the last boom module 108 ″ in the transport direction.

In FIGS. 10 and 11 it can be seen that both to the side of the conveyor belts 110 and to the side of the intermediate rollers 112, vertically aligned guide rollers 120, 122 are arranged, through which the transported flexible material strand 11 runs out of the conveyor belts 110 and the intermediate rollers 112, 118 is prevented. In Fig. 12, the device 10 according to the invention is in a partially fabricated state betil det. It can be seen that the transfer of the flexible material strand 11 from the take-off unit 36 (not shown) to the boom 38 (not shown) takes place via three roller guides 124, 126, 128.

The first roller guide 124 is arranged in a stationary manner on the housing 26. The second roller guide 126 is arranged in a stationary manner on a rotary module 130 (cf. FIGS. 13, 14). And the third roller guide 128 is arranged in a stationary manner on a boom connection 132 (cf. FIGS. 15, 16).

The rotary module 130 has a rotary module housing 134, the roller guide 126, which is shown in FIG. 13 for better understanding and not shown in FIG. 14, rests on a frame 136 and a guide plate 138 with a front round area 140 and a rear area has straight edge 142 and between freely rotatable rollers 144.

Furthermore, the rotary module housing 134 has an upper connection 146 and a lower connection 148 for the rotatable mounting 44 in the housing 26. In addition, there are bearings 150 on both sides for the pivotable mounting 42 of the boom connector 132 in the rotating module 130.

The boom connection 132 has a boom connection frame 152 with a rotary bearing 154, which is received in the bearings 150 in order to ensure the pivotable mounting 42.

It can also be seen in FIGS. 15, 16 that the third roller guide 128 again rests on a frame 156, with freely rotatable rollers 160 being arranged in a guide plate 158. In FIG. 16, the bearing 162 of these rollers 160 can be seen, which is arranged under the guide plate 158.

The guide plate 158 of the boom connection 132 has a straight edge 164, 166 on both sides. The front straight edge 164 of the boom connection 132 faces the rear straight edge 142 of the rotary module 130 in the assembled state (cf. FIG. 12), while the rear straight edge 166 faces the first intermediate roller 118a of the Boom 38 has (see. Fig. 8). The front round area 140 of the guide plate 138 of the rotary module 130 in turn covers the first roller guide 124 (see. Fig. 12), so that for each case of a possible horizontal and / or vertical pivoting of the boom 38 relative to the housing 26, a closed roller guide path 124, 126, 128, 118a.

In order to prevent a possible jamming of the material strand 11 between the roller guides 124, 126, 128, 118a and the supports surrounding them, the roller guides 124, 126, 128 or the intermediate rollers 118a can be omitted entirely and only the supports 138, 158 are formed as sliding plates for the strand of material 11.

In FIG. 17 it can be seen that the rotary module 130 has a Flebelanschl uss 168 on one side, on which a hydraulic cylinder 170 is arranged (cf. also FIG. 2), which is connected to the housing 26 on its other side. As a result, the horizontal pivoting of the boom 38 about the vertical axis 42 can be controlled.

In Fig. 18 it can be seen that the rotary module 130 has four stop points 172, 174, the lower stop points 172 being arranged on the rotary module housing 134 and the upper stop points 174 on a cross member 176. This cross member 176 is fixed to the via a shaft 178 upper connection 146 connected.

In Fig. 1 and 2 it can be seen that there is a linkage 180, which is connected to both the rotary module 130, namely the lower attachment points 172, and with the boom 38, namely between the second boom module 108 'and the third Boom module 108 "attached boom anchor points 182 (see. Fig. 8).

The rod 180 has two sides 184, 186 each with two rod parts 188, 190, with a cross brace 192 in the transition from the first rod part 188 to the second rod part 190, which connects the two sides 184, 186 with each other and stiffens them.

On this cross brace 192 there are again oppositely arranged attachment points 194. Two controllable hydraulic cylinders 196 are each connected to the upper attachment points 174 of the cross member 176 and the attachment points 194 of the linkage 186 connected, so that the vertical pivoting of the boom 38 about the horizontal axis of rotation 44 can be adjusted by targeted control of the hydraulic cylinder 196.

In order to be able to maintain the equilibrium of the device 10 for each case of the horizontal pivoting of the boom 38 about the vertical axis 42, there is a counter-boom 198 on the cross-member 176 which is opposite to the boom 38 and on which a suitable counterweight 200 is arranged. If, on the other hand, the dead weight of the device 10 on the side of the storage container 18 is large enough, it is also possible to dispense with such additional counter-jibs 18 and counterweights 200, as shown in FIG.

19 shows a section through the joint means 40 transversely to the longitudinal direction L and FIG. 20 shows a plan view of the joint means 40 in the longitudinal direction L.

It can be seen that the axis of rotation 42 is formed by two shafts 178, 202 which are each firmly connected (by means of feather key connections) to the housing 134 of the rotary module 130 and are each supported in the housing 26 with spherical roller bearings 204, 206. These spherical roller bearings 204, 206 can transmit particularly high forces without wear.

By using the split shaft 178, 202, the rotary module 130 is constructed as a cage through which the material strand 11 can be easily transported for all pivoting areas.

In addition, the axes 42, 44 lie in one plane, as a result of which the joint means 40 are designed to be particularly effective, space-saving and low-wear.

In the boom connection 132, guides 207 in the form of sliding surfaces are provided laterally in order to guide the material strand 11 laterally within the articulation means 40 and thereby center it, so that a steady transport of the material strand 11 is guaranteed even with larger horizontal pivoting. The guides 207 could, however, also be formed by rollers and the like. The movement device 14 has two chains 208, 210 (cf. FIG. 12), which can be driven separately (not shown) in order to enable both straight running or reverse running as well as cornering with appropriate synchronization. In addition, the chains 208, 210 can be telescoped to the side with respect to the chassis 212, so that the standing surface of the movement device 14 on a surface can be adjusted if necessary or the standing surface for the transport of the device 10 on a tractor or the like (not shown ) can be reduced.

In FIGS. 21 to 25, the means 16 for manufacturing are shown in greater detail.

It can be seen that the means 20 for producing the material strand covering 22 have, in addition to the pulling shoulder 32, a hose-forming device 34 which has sewing means 220 and loop-forming means 222. The forming shoulder (pulling shoulder) 32 has a deflection edge 224 for the wrapping material 30, which delimits a guide tube 226 which, at its upper end, has a slot 228 which tapers down to a narrow gap. The guide tube 226 is spaced apart from a cylinder segment-like tray 230 by a gap 229. At a distance from the tray 230 by a gap 231, a receiving tube 232 adjoins it.

The sewing means 220 are designed as a lockstitch machine whose sewing direction (direction of movement of the sewing needle along the longitudinal extension of the sewing needle) is horizontal. The sewing means 220 are preferably adapted to set two seams 233 in parallel.

By means of these sewing means 220, the two outer edges of the wrapping material 30, which are brought together in the slot 228 and placed against one another in a vertical position, are sewn together, so that the material strand wrapping 22 is formed.

The loop-forming means 222 are designed as Kemafil ^® machines, as described for example in the publications DD 110 905 A1, DE 37 05 573 C2, WO 00/34561 A1 and DE 102 59 845 A1, the relevant content of which is fully referred to is taken.

More precisely, the stitch-forming means 222 have four hook grippers 234 (mesh-n-forming parts), each around the gap 231 with respect to a longitudinal central axis of the tray 230 are arranged pivotably so that a hook gripper 234 always takes over the braided material of the hook gripper 234 placed in front of it. The tube receiving tube 232 takes on the task of Führu ngsrohres a Kemafil ^® machine.

By means of these mesh-forming means 222, the material strand 11 with the material strand cover 22 is surrounded by a mesh structure 236, which is formed from rows of stitches 238 running parallel to the longitudinal axis of the material strand 11 and wales 240 running spirally around the material strand 11, as shown in FIG. 26 .

Due to this combination of seams 233 and mesh structure 236 in cooperation with a material strand covering 22 made of a textile material, the material strand 11 itself is very durable and at the same time resilient during transport and storage and is nevertheless flexible so that it can be easily manipulated.

The gap 231 between the shelf 230 and the guide tube 232 allows the mesh structure 236 to be withdrawn from the shelf 230 (if this is already generated around the shelf 230 by the mesh-forming means 222), so that the strand of material encased in the mesh structure 236 11 can be transferred into the guide tube 232.

The tray 230 serves on the one hand to support and guide the material strand 11 between the guide tube 226 and the hose receiving tube 232.

On the other hand, the tray 230 serves to compress the material in the material track 11, for which purpose the tray is connected to a vibrator 242, which is designed, for example, as an electrically driven eccentric vibrator.

In addition, the shelf 230 serves as the basis for a level sensor 243, which comprises a rotatable wheel 243a or a similarly suitable sensor, which is articulated on a lever arm construction 243b. With the help of this level sensor 243, the parameters: filling quantity, connection speed for the opposite sides, wrapping speed and withdrawal speed depending on the level in the flexible material strand 11 are regulated so that a predetermined level, preferably within a tolerance range for the predetermined level is maintained.

The means 24 for filling the sand stored in the storage container 18 have a housing 244 with an inlet 246, which is connected to the storage container 18, and an outlet pipe 248 which extends into the feed-through pipe 226 without touching it - it therefore exists an annular gap (not shown) between outlet pipe 248 and feed-through pipe 226.

The means 24 for filling are designed as screw conveyors, with one or more screws inside the housing 244 which transport and compress the material from the reservoir 18 Vorratsbe. Preferably there are three intermeshing augers and an upper channel can be provided in which coarse material is transported. With regard to the design of the means 24 for filling, reference is made to WO 2007/147540 A1, the relevant content of which is included in full.

In Fig. 26, which shows a detailed view with a section in the horizontal plane above the lower conveyor belts 110, it can be seen that the transport of the material strand 11 takes place without interruption, namely from the take-off unit (strand feed means) 36 via a fixed guide plate 250 with corresponding Rollers 252, then over the guide plate 138 with the rollers 144, then the guide plate 158 with the rollers 160, via the intermediate roller 118b to the lower conveyor belt and intermediate roller 112, etc.

The control unit 254 of the device 10 can also be seen in FIG.

In FIG. 27, which shows a partial detailed view with a section in a vertical plane through the means 20 for producing the material strand sheathing 20, it can be seen that the hose holder 230 engages under the upstream guide tube 226, with a gap 256 being formed. This prevents the hose 22 from jamming in the area between the hose holder 230 and the guide tube 226, which ensures that the hose 22 is reliably conveyed without damaging the hose 22. It can also be seen that the gap 231 at the transition between hose holder 230 and hose receiving tube 232 is bridged by a shell element 258 which is resiliently arranged on hose holder 230 and engages in hose receiving tube 232. A gap 260 is formed between this shell element 258 and the hose receiving tube 232. Instead of or in addition to this shell element 258, one or more fingers (not shown) can also be used.

As a result, the conduction of the hose 22 is also ensured here without being damaged by jamming, and at the same time the means 20 can be wrapped around in the area between the hose holder 230 and the hose receiving tube 232. The gap 231 in connection with the resilient shell element 258 ensures that the wrapping is pulled off. The fact that the resilient shell element 258 is present means that it can be pulled off particularly easily and safely. In addition, the strand of material is also very easily transported because it can slide over the shell element 258 and is supported by it.

In Fig. 28, in which an alternative embodiment of the strand removal means 38 'of the inventive device 10 according to FIG. 1 is shown in a detailed view, it can be seen that with two successive belts 110a, 110b in the transfer area 262 between the belts 110a, 110b the belt end 264 of a belt 110a arranged upstream is arranged vertically higher than the beginning 266 of a belt 110b arranged downstream, both belts increasing in relation to the conveying direction F of the strand discharge means 38 '. This results in a more or less step-shaped transport of the material strand 11. In addition, in the transfer area 262 there is a sliding plate 268 between the belts 110a, 110b.

This effectively prevents jamming of the strand of material 11 transported in the conveying direction F and damage to the hose 20 between the two belts 110a, 110b. The material strand 11 is lifted by the step-like arrangement from an upstream belt 110a over the sliding plate 268 onto the following downstream belt 110b, so that jamming is excluded.

Instead of the slide plate 268 shown, there could also be a roller (not shown). In addition, instead of the sliding plate 268 or roller and thus in In the horizontal direction between the belts 110a, 110b there is also an overlap (not shown) between the belts 110a, 110b, so that rollers or sliding plates 268 can be dispensed with. Even if the horizontal distance between the belts 110a, 110b is not too great, the jam-free transfer will still work, even if no roller or slide plate 268 is provided.

In FIG. 30, an alternative embodiment 10 'of the device 10 according to the invention is shown, only the differences being explained below, because otherwise parts are the same.

It can be seen that this device 10 ′ additionally comprises a collecting container 300 which feeds the storage container 18 via a conveying device 302. The conveyor device 302 can be, for example, a belt conveyor. Collection container 300 and conveyor device 302 are arranged on a common platform 304 which has its own chassis 306 and is connected to the rest of the device 10 'via the coupling 308.

However, a separate chassis 306 and the coupling 308 could also be dispensed with if the collecting container 300 and the conveying device 302 were permanently connected to the rest of the device 10 '.

With this addition 300, 302, a separate feeder can be dispensed with. Instead, for example, trucks can drive directly to the collecting container 300 and dump sand into it. The sand is then transported to the storage container 18 by means of the conveyor device 302 and is available for further use.

The device 10, 10 'is now used as follows:

The device 10, 10 'is brought to the place of use by means of a low loader or the like and is unloaded there. The standing area is then brought to the required size by means of the telescopic chains 208, 210. Then the device 10, 10 'moves to its starting point, which is selected so that the device 10, 10' finds sufficient support on the ground and also a sufficiently small distance in relation to the boom 38 to the storage location of the flexible material strands 11 exists. The storage container 18 is filled with sand and, in the meantime, if necessary, refilled again via a feeder (see device 10) or via the collecting container 300 and the conveying device 302 (see device 10 '). Then the boom 38 is pivoted so that its front end is above the point at which the beginning of the material train 11 is to be deposited.

The wrapping material 30 is unrolled from the bearing 28 and pulled over the pulling shoulder (form shoulder) 32 into the guide tube 226 and thereby formed into a tube. The two lateral ends of the wrapping material 30 are guided together through the slot 228 and sewn over it with the sewing means 220 to form the tube 22, which was also first closed at its front end. Then sand is filled into the hose 22 formed by means of the filling means 24.

The tube 22 filled with material is guided over the tray 230 and vibrated with the vibrator 242, as a result of which the material in the tube 22 is compressed.

Then the filled hose 22 is sheathed with the mesh-forming means 222 with the mesh structure 236 and the filled and sheathed hose 22 is then pulled off by the pulling means 36 and conveyed to the boom 38 via the hinge unit 40.

In the extraction means 36, the contact pressure of the upper conveyor belt 104 is adjusted and the speeds of the conveyor belts 110 of the boom 38 and the conveyor belts 102, 104 of the extraction unit 36 as well as the speed of the hose formation device 34 and the speed of the filling means 24 are synchronized and adjusted so that a flexible material strand 11 results (cf. FIG. 29), which is evenly filled with sand over its entire length and thus has a constant diameter.

The fill level in the hose 22 is continuously monitored by the fill level sensor 243 and the parameters: fill quantity, connection speed for the opposite sides, wrapping speed and take-off speed depending on the fill level in the hose 22 are regulated in such a way that a preset fill level, if necessary, taking into account a tolerance, is achieved permanently in order to guarantee constant quality.

After the flexible material strand 11 has reached the front intermediate roller 188b of the boom and has arrived at the storage location from there, the device 10, 10 'is moved, if necessary, by means of the movement device 14 and / or the boom 38 is pivoted so that the flexible material strand 11 is successively the planned Filing path is stored accordingly.

If a change of direction is to take place in order to generate a second adjacent flexible material strand path 216 or a third applied flexible material strand path 218 in addition to a first flexible material strand, the filling speed of the filling means 24 and / or the withdrawal speed can be reduced in advance for a certain time the haul-off unit 36 and the transport speed of the boom 38 can be increased, as a result of which the flexible material strand 11 has less sand as a filling over a certain section. The flexible material strand 11 can then be bent by 180 ° in this section in order to change direction.

When a sufficient length of material strand 214, 216, 218 has been produced, the wrapping material 30 is severed and the rear end of the hose 22 produced is sewn and thereby closed, the internal advance of the device 10, 10 'being stopped.

If, on the other hand, after the wrapping material 30 has been completely used up, additional material strand sections 214, 216, 218 are required, then another roll of wrapping material 30 is loaded and the beginning of the new wrapping material 30 is sewn to the end of the old wrapping material 30, with no advance within the device 10, 10 'takes place until the sewing has been completed. The described procedure can then be carried out again, whereby an endless tube 22 can in principle be produced in a very safe manner and filled with sand and deposited as a material strand 11.

On the one hand, the movement device 14 can be used to transport the device 10, 10 ′. On the other hand, the entire device 10, 10 'can also be transported on a low-loader or the like. The movement device has a central part and chain drives arranged thereon, the chain drives being able to be moved in and out with respect to the central part. In the case of transport on a low-loader, a drive-in takes place in order to keep the device 10, 10 'as narrow as possible for transport on motorways and the like The largest possible stand base is guaranteed.

It has become clear from the above illustration that the present invention provides a possibility for producing flexible material strands 11 which avoids the disadvantages of the prior art. In principle, the strands of material 11 can be produced endlessly. Even with large diameters of the material strands 11, the material strands 11 can be freely handled. In addition, the production is scalable with regard to the dimensions of the material strand 11. In addition, it is possible to lay the strand of material 11 directly after production. In this way, such flexible material strands 11 can be provided very simply and inexpensively, for example for the construction of flood protection systems 46, military protective walls or for targeted landscaping.

Unless stated otherwise, all of the features of the present invention can be freely combined with one another. In particular, features specified in the claims can also be combined with features from the feature sets. Unless otherwise stated, the features described in the description of the figures can also be freely combined with the other features as features of the invention.
