Definitions

  • the invention relates to a system and a method for connecting or solidifying a web of fiber material with a nonwoven by means of water jets, with a first circumferential belt on which a web of fiber material can be deposited and a device for introducing a nonwoven into the system, with a further subsequent circumferential belt on which the fleece with the web of fibrous material can be connected or solidified by means of water jets.
  • EP 1929080 B1 known to connect loose fibers with a fleece, in which the loose fibers are always supported and guided by a tape from below and are simultaneously deposited on a fleece.
  • This method and the associated system are very complex, since an absolutely parallel guidance of the strips over a longer section is required.
  • This is structurally very complex to implement, since constant tension is required between the belts and both belts must have an identical speed at every point in order not to introduce uncontrolled distortions into the end product.
  • the WO 2004/097097 A1 and the WO 2005/118934 A1 disclose a method for producing a fleece by means of airlaid, a fibrous web being deposited upside down on a circulating conveyor belt.
  • the fibrous web is stabilized in that a further fibrous web, for example pulp, is connected to the airlaid fibers with a binding agent by means of mechanical compaction. It is a dry process in which the fibers are deposited with the help of a vacuum. Wet laid short fibers cannot be processed in this way.
  • the EP 2116645 A1 and the US 2003/0021970 disclose a method for the production of a sandwich fleece, in which a spunbond or a fleece made of synthetic fibers is deposited between two carded fleeces and solidified. Wet laid short fibers cannot be processed in this way.
  • the object of the present invention is to create a method and a system for connecting a web of loose fibers with a fleece, with which a compact and inexpensive system can be produced.
  • the system for connecting or solidifying a web of fibers with a fleece by means of water jets comprises at least one first circumferential belt on which a web of fiber material can be placed and a device for introducing a fleece into the system, the another subsequent revolving belt is arranged downstream, on which the fleece with the web of fibrous material can be connected or solidified by means of water jets.
  • the invention is characterized in that the web of fibrous material from the first circumferential belt can first be deposited on the fleece and then the fibrous material together with the fleece is transferred to the subsequent belt for connection or solidification by means of water jets.
  • the term “depositing the fibrous material on the fleece” does not require that the fleece has to assume an approximately horizontal position so that the loose fibers or the web of fibrous material are transferred to the fleece and form a first connection. For this purpose, it is sufficient that, for example, on the sloping section of the circumferential belt, a first contact is made between the fleece and the web of fibrous material, so that the adhesion between the layers causes a first light connection, even if the fleece is arranged spatially above the fibrous material is.
  • connection between the fleece and the fibrous material takes place by means of water jets, whereby at the same time a solidification of the fibrous material in itself, but also with the fleece takes place, since the fibers swirl with and into each other.
  • joining of nonwoven and fiber material also means consolidation at the same time.
  • the web of fibrous material is transferred with its upper side onto a circumferential belt which is arranged in front of the further following belt for hydroentangling.
  • very light fibrous materials are supported and transferred onto a preferably horizontal or inclined belt from an overhead position before the fleece is introduced into the system and connected to the fibrous material.
  • This overhead laying enables the connection of the upper side of the fiber material with the fleece, whereby the flat underside of the fiber material reaches the outside of the product and this achieves a visually better quality.
  • the device for introducing the fleece into the system is preferably arranged between the belts.
  • the result is a space-saving solution in which the fiber material is first placed upside down on a further belt and can then be placed with the upper side on the fleece, before the two are connected and solidified together.
  • the arrangement of the device for introducing the fleece in the area of a roller of the circulating belt has the advantage that the upper side of the web of fibrous material is placed on the fleece and the fibrous material is compacted between the roller and the incoming fleece.
  • the roller of the circulating belt is arranged as a deflection roller around which the belt changes its direction. Because the fibrous material with the fleece is guided around the roller by a deflection angle, the fibrous material is first compressed or compacted.
  • the fleece is introduced into the system with a defined pre-tension in order to generate minimal contact pressure on the fiber material.
  • the device for introducing the fleece into the system can be designed as a roller.
  • an unwinding device or a carding device can be integrated into the system in a free spatial arrangement, whereby the fleece can enter the system directly or indirectly via further rollers.
  • the device for introducing the fleece into the system can be designed as a suction drum, the suction drum advantageously being equipped with at least one first nozzle bar, so that a first connection or solidification between the fleece and fiber material can take place here.
  • the arrangement of the suction drum in the direction of material transport after the roller enables a multi-stage connection or consolidation of the fibrous material with the fleece.
  • the suction drum can advantageously be arranged in the material transport direction between the first revolving belt and the subsequent belt for connecting / solidifying the fibrous material with the fleece, the fibrous material being transferred with its upper side to the suction drum, and the fleece being introduced into the system in this way is that by means of water jets, the underside of the fiber material can be connected or solidified with the fleece.
  • this alternative enables different variants in the surface structure of the end product.
  • the suction drum is arranged in the material transport direction between the first revolving belt and the following belt for connecting / solidifying the fibrous material with the fleece, the fibrous material being transferred with its upper side to the suction drum and a fleece in this way into the system is introduced that by means of water jets, the upper side of the fibrous material is connected or solidified with the fleece.
  • At least one water bar can be arranged within the revolving belt on which the loose fiber material is deposited in order to detach the web of fiber material from the belt.
  • the distance between the revolving belt on which the loose fiber material is deposited and the belt on which the fleece is connected to the fiber material by means of water jets is greater than the thickness of the fleece with the fiber material deposited thereon.
  • the method according to the invention for connecting or consolidating a web of fibrous material with a fleece by means of water jets provides that a web of fibrous material can be placed on a first circumferential belt, and that a fleece for connection with the web of fibrous material can be introduced into the system, wherein the fleece with the web of fibrous material can be connected or solidified to one another by means of water jets on a further following circumferential belt.
  • the web of fibrous material is placed on the fleece and then the fibrous material together with the fleece is transferred to the next following belt for connection or solidification by means of water jets.
  • the web of fibrous material can be transferred with its upper side onto a circumferential belt which is arranged in front of the further following belt for hydroentangling.
  • the fiber material is first transferred overhead to the following belt and only then connected to the fleece.
  • An inclined screen former 1 is arranged below a rotating screen belt 10.
  • the screen belt 10 which can be designed as an endless belt, runs around various rollers 12 and has an inclined section 11 which rises in the running direction of the screen belt by the angle a.
  • the inclined screen former 1 is arranged below the screen belt 10, on its covering 2 the screen belt 10 is supported.
  • the inclined screen former 1 can have a plurality of suction zones 3 to which different pressures or negative pressures are applied.
  • the vacuum sources can preferably be designed as controllable / regulatable vacuum pumps.
  • each fiber suspension 8.1, 8.2 and 8.3 contains, in addition to water, a certain content of solids, which in turn consists of fibers and other additives.
  • the fiber suspensions 8.1, 8.2, 8.3 lamellae (not shown) are arranged with which the layer thickness of the fiber suspensions can be varied individually or in total. Since the lamellae separate the fiber suspensions 8.1, 8.2 and 8.3 from one another, they are dewatered one after the other on the inclined wire former 1. This prevents the fiber suspensions 8.1, 8.2 and 8.3 from mixing and improves the purity of the individual layers of fiber material.
  • each layer of a fiber suspension 8.1, 8.2 and 8.3 can be exposed to a separate negative pressure, with which different mixtures of water with fibers can be processed in each fiber suspension.
  • the fiber suspensions 8.1 and 8.3, which form the outer layers or the cover layer for the middle layer of fiber suspension 8.2 during further processing, can at least partly consist of short synthetic fibers such as polyester, polyamide or polyolefin. Mixtures of synthetic and natural fibers are also possible.
  • the outer layers can also consist of 100% pulp.
  • the middle Fiber suspension can consist of natural fibers that have a high water retention capacity.
  • the thickness of the layers can be adjusted by means of the lamellae in that the task of the fiber suspensions 8.1, 8.2 and 8.3 via the headbox 8 can be varied.
  • layers of the same thickness can be produced, or the layers can be produced with a gradation of, for example, 10%, 80% and 10% thickness.
  • the weight per unit area of each layer of fibrous material 9 can also be set indirectly via this.
  • the sieve belt 10 which is permeable to liquids and gases, transports the fiber suspensions 8.1, 8.2 and 8.3 arranged one above the other via the inclined section 11 over the inclined screen former 1. Due to the force of gravity and the negative pressure that acts on the fiber suspensions 8.1, 8.2, 8.3, the fiber suspensions are dewatered, which in this example forms a web of fiber material 9 with three layers of fibers.
  • the web of fibrous material 9 is first transported in the direction of the arrow over a horizontal section then further over a sloping section on the belt 10. After the sloping section, the web of fibrous material 9 is passed around a roller 12 upside down onto a further circulating belt 14, which is also guided around several rollers 13.
  • the belts 10 and 14 run at least partially approximately parallel, the distance between the belts 10, 14 being greater than the thickness of the web of fibrous material 9.
  • the belts 10, 14 can also be arranged at such a distance that the web is compressed from fiber 9.
  • at least one water bar 17 is arranged within the revolving belt 10, with which the web of fibrous material 9 is pre-consolidated and detached from the belt 10.
  • the associated suction device 18 is located within the circulating belt 14. Downstream of the fiber material 9 and below the inclined screen former 1 with the circulating belt 10, there is another circulating belt 16 on which the fibrous web 9 is further processed.
  • the circumferential belt 16 is arranged in such a way that there is no overlap or running parallel to the belt 10.
  • An infeed roller 21 is arranged between the belts 14 and 16, via which a fleece 20 is introduced under the web of fibrous material 9 onto the circulating belt 16. Since the web of fibrous material 9 is transported upside down by the circulating belt 10 after the sloping section, the upper side of the web of fibrous material 9 is deposited on the fleece 20.
  • the fleece 20 is unwound from a store or a roll of material.
  • a card can also be arranged with which the fleece 20 can be fed directly into the in Figure 1 Solidification plant shown is introduced.
  • the distances between the rollers 13, 21 and 15 are kept small on the one hand to minimize the gusset for the further transport of the fibrous material 9, on the other hand the infeed roller 21 can be designed to be adjustable in order to introduce the fleece 20 quickly.
  • the final connection between the nonwoven 20 and the fibrous material 9 takes place in the area of the belt 16 in that at least one water bar 17 connects the fibrous material 9 to the nonwoven 20 and compresses it.
  • the water jet from the water beam 17 hits the fibrous material 9, which is connected to the fleece 20.
  • a revolving belt 10 in which a fiber application 4 is arranged over an inclined section 11, with which, for example, pulp can be applied as loose fibers.
  • a fiber application 4 is arranged over an inclined section 11, with which, for example, pulp can be applied as loose fibers.
  • the web of fibrous material 9 is transported onward over a horizontal section in the direction of material flow to a sloping section, and passed overhead over a roller 12 onto a fleece 20. So that the dry fibers do not slip off the belt 10, a fiber moistening system (not shown) can be arranged, for example, on the horizontal section of the belt 10, so that the loose composite of dry fibers has a certain strength.
  • the fleece 20 can likewise be unwound from a roll or supplied directly from a carding machine.
  • the delivery of the fleece 20 takes place in the area of the roller 12 in such a way that a first compacting takes place between the fleece 20 and the web of fibrous material 9.
  • This connection is reinforced on a subsequent belt 14 by at least one water beam 17.
  • the following belt 14 is arranged below the belt 10 and runs at least partially parallel to it.
  • the distance between the bands 10, 14 is greater than the thickness of the fleece 20 with the web of fibrous material 9.
  • the fleece 20 can also be applied to the belt 14 via an infeed roller 21, the web out in the area of the infeed roller 21 Fibrous material 9 is deposited upside down on the fleece 20.
  • the embodiment of Figure 3 likewise shows two circumferential belts 10, 14 which are at least partially arranged in parallel, the circumferential belt 14 being arranged below the belt 10.
  • a web of fibers is applied to the belt 10 via a fiber application 4 or via an inclined wire former 1.
  • an infeed roller 21 is arranged, via which a fleece 20 is applied to the web of fibrous material 9.
  • a compaction takes place between the fleece 20 and the fibrous material 9, although the distance between the bands 10, 14 is greater than the thickness of the fleece 20 with the fibrous material 9.
  • FIG. 3a shows in a further arrangement at least one water bar 17 within the belt 10, whereby the web of fibrous material 9 is detached from the belt 10. There is no compaction at this point, since the distance between the bands 10, 14 is greater than the thickness of the fleece 20 with the fibrous material 9.
  • the embodiment in Figure 3b shows a suction drum 22, which is acted upon by at least one water beam 17, instead of the infeed roller 21.
  • the web of fibrous material 9 is thus consolidated with the nonwoven fabric 20, with subsequent compaction between the nonwoven fabric 20 and the fibrous material 9 due to the deflection around the roller 12.
  • the subsequent water bars 17 within the band 10 also ensure a complete detachment of the fibrous material 9 from the band 10, since here too the distance between the bands 10, 14 is greater than the thickness of the fleece 20 with the fibrous material 9.
  • the subsequent further consolidation between the fleece 20 and the web of fibrous material 9 takes place in an area on the belt 14 in which the belts 10, 14 no longer run parallel.
  • the embodiment of Figure 4 also shows in the area of a sloping section an infeed roller 21 around which a fleece 20 is brought into contact with the web of fibrous material 9. Over a Subsequent deflection by a roller 12, a compaction takes place between the fleece 20 and the web of fibrous material 9. Instead of being deposited directly on a belt 14 arranged below the belt 10, the fleece 20 with the web of fibrous material 9 is at least partially around a suction drum 22 out, on which the fleece 20 is consolidated with the fibrous material 9 by means of a water beam 17. A subsequent roller 19 is used for further transport onto a revolving belt 14 with at least one further subsequent water beam 17.
  • the fibers 9 deposited on the belt 10 are consolidated in the first horizontal section by means of water beams 17.
  • the solidified fiber material 9 is detached from the belt 10 by a water bar 17 and transferred with its upper side to the suction drum 22 and guided around it.
  • the suction drum 22 rotates clockwise.
  • a fleece 20 is fed via an infeed roller 21 so that a connection between the fleece 20 and the underside of the fibrous material 9 takes place over a partial area of the circumference of the suction drum 22 in that at least one water bar 17 connects the two.
  • Subsequent rollers 19 ensure that it is transported further onto a further revolving belt 14, on which the fleece 20 is connected again to the fibrous material 9 by means of water bars 17.
  • a suction drum 22 is arranged in the region of the sloping section.
  • a fleece 20 is guided around the suction drum 22.

  • the fiber material 9 is located below the fleece 20 and is on the following circumference of the suction drum 22 by means of water bar 17 with its top with the Fleece 20 solidified.
  • Rollers 19 arranged below ensure a transfer to a further revolving belt 14, which can be arranged below belt 10, with subsequent further consolidation between fleece 20 and fiber material 9 by means of water bars 17.
  • All the exemplary embodiments have in common that the fibers are laid down on the first belt 10 as loose pulp or wet-laid by means of an inclined screen former 1.
  • the fleece 20 can be fed into the system as a carded fleece from a supply roll or directly as a carded fleece from a carder in the system.
  • the fleece 20 can be produced from short or continuous fibers.
  • the connection of the fibrous material 9 with the fleece 20 does not take place in the area of a parallel guide between two bands.
  • the loose fibers do not have to be connected to the fleece upside down between two tapes. Aligning the belts to one another and synchronizing the belt speeds are therefore not necessary.
  • the two layers can be compacted by means of bands arranged in parallel. However, this is not necessary for the process and the system.
  • the water beams create a turbulence and thus solidification of the fibers with one another or, if the pressure is lower, cause the fibers or the fleece to be detached from a belt or drum.
