Definitions
- the invention relates to a device for solidifying a material web according to the preamble of claim 1.
- EP-A-0 959 076 discloses a device for consolidating the fibers of a material web of natural and / or artificial fibers of any type, in which a belt drum compacting of the fiber web takes place. It consists of the following characteristics or is designed as follows:
- a first endless belt supporting the fiber web which is tensioned between at least two rollers and deflected
- a second belt also tensioned between at least two rollers, which is connected to the first endless belt and whose workstring lies opposite the workstring of the first endless belt in the same direction as that of the first endless belt;
- the two working strands of the two endless belts are directed conically toward one another in their longitudinal extent, so that the fiber web lying on the working strand of the first endless belt (the pre-fleece, the pile) is increasingly compressed between the leading endless belts,
- the device of this type has the advantage that the pre-fleece, the voluminous leading fiber web, between the two endless belts is slowly increasing and compressed with uniform pressure from above and below without shearing and only if they see between the two endless belts is recorded, is wetted on the Vernade- drum.
- the construction is complex and therefore too expensive for some products.
- a first endless belt supporting the fiber web which is tensioned between at least two rollers and deflected
- a second endless belt also guided stretched between at least two rollers, which rotates the Hästrum of the first endless belt opposite lying Hätrum in the same direction as that of the first endless belt,
- the two working strands of the two endless belts are conically directed toward one another at the inlet in their longitudinal extension, so that the fiber web lying on the working strand of the first endless belt is increasingly compressed between the leading endless belts,
- Nozzle bar with a suction for netting the fiber web is provided.
- DE 10 2005 055 939 B3 shows a nozzle beam for producing fluid jets, which serve to solidify a fiber web.
- the Nozzle strip contains a replaceable nozzle strip, which contains the outlet openings for the fluid.
- the outlet openings may be arranged in a row, but also in two or more rows parallel to each other.
- the outlet openings have a distance from each other and diameter, which depend on the purpose.
- pressurized water but in principle also superheated steam can be used.
- the object of the present invention is to propose a simple device for compressing and first applying a Flores consisting of fibers and / or filaments.
- the invention is based on a device for solidifying a material web formed from fibers and / or filaments, comprising a wire belt carrying the material web, a nozzle beam arranged above the wire belt for impinging the material web with a pressurized fluid in the form of a plurality arranged in at least one row of fluid jets, arranged below the screen belt and cooperating with the nozzle beam suction with a suction, wherein in the area of the Absaugspaltes the fluid jets hit the web.
- the fluid is applied in the rear region of the suction gap in the conveying direction of the material web.
- the material web, the fiber and / or filament web experiences no mechanical compaction, compaction or guidance until fluid is applied.
- the fluid jets In the case of an enlarged suction area, the fiber and / or filament pile is stabilized and also slightly compacted, depending on the absorption capacity.
- the invention avoids that the fiber and / or filament web which is moved in the direction of fluid application is upset by the fluid jets or wrinkles form on the surface thereof. Disturbances in the fleece quality are thus avoided.
- the suction is designed as a connected to a vacuum cleaner chamber, which is bounded in the transport direction of the web by a respective plastic existing bar.
- the blowing device has air guide elements.
- the air guide elements of the blowing device are adjustable. The compacting effect of the blowing air can thus be adjusted depending on the prevailing conditions.
- the pile of the material web in the conveying direction is different strong acted upon with blown air.
- an air flow with a predetermined strength and direction is blown directly into the area of the suction gap.
- a second air flow with different strength and / or direction acted upon in the area in front of the suction gap the material web and stabilizes this already before it is flowed through above the Absaugspaltes of air.
- the web carrying the web is running straight stretched, the Absaugspalt is located directly below the screen belt.
- the web carrying the web passes around a needling drum with a permeable surface, wherein the suction gap in the interior of the needling drum cooperates with the underside of the permeable surface.
- a conveyor belt S which is rectilinearly stretched around guide rollers, not shown, carries a material web F which consists of fibers and / or filaments and which is provided as un-sealed pile by a carding or spunbonding installation largely un-solidified and transported in the direction of the arrow ,
- a nozzle beam D extending over the width of the material web F is arranged, on the underside of which a multiplicity of outlet openings for a fluid under pressure are arranged.
- it is high-pressure water, according to the pile of the material web F with a plurality of water jets W is applied.
- a row outlet openings for the water jets W are in a, not shown, replaceable nozzle strip. It is also possible to use a nozzle strip with outlet openings arranged in a plurality of spaced-apart rows.
- an extraction A is arranged below the material web F carrying conveyor belt S, which is connected via a line system with a separator AS together with downstream Saugventilator SV.
- the separator AS the water is separated from the water-air mixture, conveyed away via the downstream suction pump SP and fed to a water treatment, not shown.
- the suction A is a over the width of the conveyor belt S extending chamber which is limited in the transport direction of the web F of two made of plastic strips L1 and L2.
- the web F of the formed by the strips L1, L2 Absaugspalt is closed.
- the representation of the strips L1, L2, the nozzle beam D and in particular the size ratios of the components is shown purely in principle in the figure.
- the suction gap formed by the strips L1, L2 has a width b.
- the nozzle beam D with its exiting at the bottom water jets W is offset in the transport direction of the web F towards the rear of the Absaugspaltes, such that the water jets W not centrally but closer to the rear strip L2 Absaugspaltes in this or the web F enter.
- the distance of the entrance of the water jets W from the rear rail L2 is indicated by c, and from the front rail L1 by a.
- the material web F in the front region experiences a greater throughput than in the rear region (distance b to the strip L2).
- This volumetrically stronger absorption of the material web F in the front region stabilizes the pile, which accumulates on the water jets W and thereby experiences a compressive force against the transport direction.
- the stronger absorption of the Flores before the water jets W avoids bulging of the Flores before the first solidification by the water jets W.
- a blowing device is arranged in the conveying direction of the material web F in front of the nozzle beam D, is blown by means of the air in the area a of the suction on the surface of the web.
- the material web F to be consolidated consisted of a spunbonded nonwoven made of polypropylene (PP) with a denier of 1.8 denier.
- the spunbonded fabric was only lightly calendered after laying and then acted upon hydrodynamically according to the invention.
- the water pressure in the first nozzle bar D was 80 bar, the suction was applied with 120 mbar vacuum.
- the suction gap had a width b of 12 mm, the water jets W had a distance a of 10 mm from the front strip L1 of the suction gap.
- the first hydrodynamic needling without compaction could be carried out with a noticeably lower pressure, which additionally reduced the risk of bulking of the flores.
- a significantly more homogeneous nonwoven fabric could be produced without interference.
