Abstract

The method involves providing a support with two three-dimensional molds, and applying a non-woven fiber web or fleece (16) to the three-dimensional molds by non-ordered depositing of fibers on the molds. The pre-formed non-woven fiber web is compacted to produce a three-dimensional felt body (25) after removing the non-woven fiber web from the support, where the non-woven fiber web is compacted by the action of an amorphous medium e.g. fluid or heat, on the non-woven fiber web. An independent claim is also included for a device for manufacturing spatial felt objects i.e. brassiere cups, comprising a support.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von räumlichen Gegenständen aus Filz oder filzartigen Materialien sowie einer Vorrichtung zur Herstellung solcher Produkte.The invention relates to a method for the production of spatial objects made of felt or felt-like materials and a device for producing such products.

Aus der US 4,714,647 sind eine Vorrichtung und ein Verfahren zur Herstellung eines Filzbands bekannt. Dazu ist ein um zwei Rollen umlaufendes poröses Band vorgesehen, oberhalb dessen mehrere Spinnbalken vorgesehen sind. Diese geben geschmolzenen Kunststoff in Faserform ab. Durch Vakuum wird dieser auf dem porösen sich unter den Düsenbalken fortbewegenden Band abgelegt. Die sich bildende Faserschicht wird als Faserflor-Band abgezogen. Es entsteht ein flächenhaftes Gebilde.From the US 4,714,647 For example, an apparatus and a method for producing a felt belt are known. For this purpose, a circulating around two rollers porous band is provided, above which a plurality of spinning beams are provided. These give off molten plastic in fibrous form. By vacuum this is deposited on the porous moving under the nozzle bar moving band. The forming fiber layer is peeled off as a batt. The result is a planar structure.

Ein ähnliches Verfahren zur Herstellung schmelzgeblasener Vliesstoffe ist aus der DE 199 56 368 A1 und aus der US 3,825,379 bekannt, die auch Aufschluss über den Aufbau entsprechender Schmelzblasköpfe geben. Der von den Schmelzblasköpfen erzeugte Faserstrom wird auf eine Kollektortrommel geleitet und dann von dieser als Band abgenommen. Es entsteht ein flächenhaftes Vlies. Aus der DE 10 2004 030 393 A1 ist ein Verfahren zur Herstellung genoppter Vliesstoffe bekannt. Dazu wird ein Faserflor auf einer Siebtrommel mit einer Lochstruktur abgelegt. Beim Verfestigen mittels Wasserstrahlen bilden sich durch die vorhandenen Löcher die gewünschten Noppen an dem Vliesstoff.A similar process for the production of meltblown nonwovens is known from DE 199 56 368 A1 and from the US 3,825,379 known, which also provide information about the construction of appropriate melt blown heads. The fiber stream generated by the meltblown heads is passed to a collector drum and then removed from this as a belt. The result is a planar fleece. From the DE 10 2004 030 393 A1 is a method for producing knopped nonwovens known. For this purpose, a batt is placed on a sieve drum with a hole structure. When solidifying by means of water jets form the desired nubs on the nonwoven fabric through the existing holes.

Außerdem beschreibt die WO 01/53587 A1 die Herstellung räumlich geformter Vliesstoffe durch Umformen eines zunächst flächenhaften Vlieses in einer entsprechenden Formvorrichtung.In addition, the describes WO 01/53587 A1 the production of spatially shaped nonwovens by forming an initially planar web in a corresponding molding device.

Es ist Aufgabe der Erfindung ein kostengünstiges Verfahren zum Herstellen von dreidimensional geformten Gegenständen aus ungeordneten Fasern, insbesondere Büstenhalterkörbchen anzugeben.It is an object of the invention to provide a cost-effective method for producing three-dimensionally shaped objects from disordered fibers, in particular brassiere cups.

Weiter ist es Aufgabe der Erfindung eine entsprechende zur Durchführung des Verfahrens geeignete Vorrichtung anzugeben.It is another object of the invention to provide a suitable device suitable for carrying out the method.

Diese Aufgaben werden mit dem Verfahren nach Anspruch 1 und der Vorrichtung nach Anspruch 11 gelöst:

  • Bei dem erfindungsgemäßen Verfahren wird zur Aufnahme eines Faserflors oder Faservlies ein Träger bereitgestellt, der eine dem herzustellenden Gegenstand entsprechende Form aufweist. Auf diesem Träger werden Fasern ungeordnet abgelegt. Es entsteht ein noch wenig oder nicht verfestigter Körper, der dann durch geeignete Maßnahmen zu einem Vlies oder Filzkörper verfestigt werden kann. Damit ist für die dreidimensionale Gestaltgebung kein Zusatzarbeitsgang erforderlich. Bereits beim Ablegen der zum Beispiel extrudierten Fasern auf dem Träger wird die dreidimensionale Form gebildet. Die "dreidimensionale Form" ist in zumindest zwei verschiedenen Richtungen gekrümmt. Der Träger kann dazu entsprechende konvexe oder konkave Formen aufweisen. Im Fall der Herstellung von Büstenhaltern hat der Träger die Innenform oder die Außenform des später gewünschten Körbchens.
These objects are achieved by the method according to claim 1 and the device according to claim 11:
  • In the method according to the invention, a support is provided for receiving a batt or non-woven fabric, which has a shape corresponding to the article to be produced. On this carrier fibers are deposited disorderly. The result is a little or not solidified body, which can then be solidified by suitable measures to a fleece or felt body. Thus, no additional operation is required for the three-dimensional design. Already when depositing the example extruded fibers on the carrier, the three-dimensional shape is formed. The "three-dimensional shape" is curved in at least two different directions. The carrier may have corresponding convex or concave shapes for this purpose. In the case of brassieres, the wearer has the inner shape or outer shape of the later desired basket.

Der Träger kann eine poröse oder siebartige Struktur aufweisen. Durch eine Druckdifferenz an dem Träger können die Fasern gezielt auf diesem abgelegt werden. Zur Erzeugung der Druckdifferenz kann ein Unterdruck unter dem Träger genutzt werden. Auch kann ein beim Extrudieren von Fasern bestehender Überdruck das Ablegen der Fasern auf dem Träger unterstützen. Durch Abziehen des entstehenden Bandes mit den entsprechenden Formen nach einer Richtung entsteht so ein schon dreidimensionale Formen aufweisendes Tuch mit dem gewünschten Körbchen oder sonstigen Formen. Das Tuch kann dann durch weitere Bearbeitungsschritte, zum Beispiel Thermobonden, Imprägnieren, Wasserstrahlverfestigen oder ähnliches verfestigt werden.The carrier may be a porous or sieve-like structure respectively. By a pressure difference on the carrier, the fibers can be stored specifically on this. To generate the pressure difference, a negative pressure can be used under the carrier. Also, over-extrusion of fibers may assist in depositing the fibers on the backing. By subtracting the resulting band with the corresponding shapes in one direction so creates a already three-dimensional shapes exhibiting cloth with the desired basket or other shapes. The cloth can then be solidified by further processing steps, for example thermal bonding, impregnation, hydroentanglement or the like.

Vorzugsweise kann eine erste Verfestigung des Faserflors bereits auf dem Träger vorgenommen werden. Dazu kann zum Beispiel in Nachbarschaft eines Spinnbalkens ein Wasserstrahldüsenbalken angeordnet sein, der eine erste Vorverfestigung und Fixierung der Fasern vornimmt, bevor eine weitere Fixierung zum Beispiel in Form eines Thermobonding-Prozesses und/oder einer Wasserstrahlverfestigung erfolgt.Preferably, a first solidification of the batt can already be carried out on the carrier. For this purpose, for example, a water jet nozzle bar may be arranged in the vicinity of a spinneret, which carries out a first preconsolidation and fixation of the fibers, before further fixing takes place, for example, in the form of a thermobonding process and / or hydroentanglement.

Weiter kann vorgesehen sein, dass die Körbchen oder sonstigen 3D-Formen aus dem hergestellten verfestigten Tuch durch geeignete Maßnahmen ausgeschnitten werden, zum Beispiel durch einen Stanzvorgang oder durch einen Laserschneidvorgang. Auch kann sich eine weitere Bearbeitung, beispielsweise durch Bedrucken, Säumen, Konfektionieren usw. anschließen.It can further be provided that the baskets or other 3D shapes are cut out of the produced solidified cloth by suitable measures, for example by a punching process or by a laser cutting process. Also, a further processing, for example, by printing, hemming, packaging, etc. join.

Die Verfestigung des Faserflors durch Wasserstrahlen wird bevorzugt. Ergänzend oder alternativ kann die Verfestigung jedoch auch durch andere formlose Medien, wie beispielsweise Gasstrahlen, Strahlen eines organischen Fluids, Wärme, einen Klebstoff oder ein sonstiges Klebemittel oder Lösungsmittel erfolgen. Dies gilt sowohl für die Vorverfestigung des Faserflors auf dem Träger wie auch für eine sich an die Abnahme des noch nicht vollständig verfestigten Filztuchs oder Vliesstoffs von dem Träger anschließende Verfestigung.The solidification of the batt by water jets is preferred. Additionally or alternatively, the solidification may, however, also be effected by other informal media, such as, for example, gas jets, blasting of an organic fluid, heat, an adhesive or another adhesive or solvent. This applies both to pre-consolidation the batt on the support as well as for the subsequent solidification of the not yet fully consolidated felt cloth or nonwoven fabric from the carrier.

Das vorgestellte Verfahren gestattet die Kombination unterschiedlicher Fasermaterialien in dem dreidimensionalen Filzkörper. Zum Beispiel können nacheinander Fasern aus verschiedenen Materialien auf dem Träger abgelegt werden. Es bilden sich so in dem Faserflor Lagen aus unterschiedlichen Fasern, die dann in dem fertigen Tuch bzw. Filzkörper untereinander verbundene Schichten mit unterschiedlichen Eigenschaften bilden. Zum Beispiel können strukturgebende feste Faserschichten und Fasern, die einen Tragekomfort erbringen, miteinander kombiniert werden.The presented method allows the combination of different fiber materials in the three-dimensional felt body. For example, successively fibers of different materials can be deposited on the carrier. Layers of different fibers thus form in the batt, which then form interconnected layers with different properties in the finished fabric or felt body. For example, structural solid fiber layers and fibers that provide comfort can be combined with each other.

Alternativ ist es möglich, in dem Tuch oder Filzkörper ein Gemisch aus verschiedenen Fasern anzuordnen, um die Eigenschaften verschiedener Fasermaterialien miteinander zu kombinieren.Alternatively, it is possible to arrange in the cloth or felt body a mixture of different fibers in order to combine the properties of different fiber materials.

Auch ist es möglich, Bikomponentenfasern zu nutzen, die beispielsweise einen Kern aus einem ersten Material und eine Umhüllung aus einem zweiten Material haben. Wenn Büstenhalterkörbchen hergestellt werden sollen, ist es in der Regel gewünscht, dass sie eine gewisse Elastizität haben. Dazu werden die extrudierten Fasern beispielsweise so erzeugt, dass sich die einzelne Faser kräuselt und dadurch einen Elastizitätseffekt bewirkt. Die gekräuselte oder ungekräuselte Faser kann aus einem Elastomer bestehen. Es kann eine Bikomponentenfaser dadurch hergestellt werden, dass eine Komponente die Festigkeitskomponente darstellt und beispielsweise in der Mitte als Seele angeordnet ist. Eine äußere Komponente kann die Seele einhüllen und den Weichheitsgrad der Faser bestimmen.It is also possible to use bicomponent fibers which, for example, have a core of a first material and a sheath of a second material. When bra cups are to be made, it is usually desirable that they have some elasticity. For this purpose, the extruded fibers are for example generated so that the individual fiber curls and thereby causes a elasticity effect. The crimped or uncrimped fiber may be made of an elastomer. A bicomponent fiber may be made by having one component as the strength component and being centered, for example, as a core. An outer component can envelop the soul and determine the degree of softness of the fiber.

Wird ein Fasermehrschichtaufbau, beispielsweise zur Herstellung Büstenhalterkörbchen gewünscht und befindet sich die Körbcheninnenseite auf der dem Träger zugewandten Seite, werden zum Beispiel zuerst die weichen Fasern durch einen ersten Spinnbalken abgelegt. In einem zweiten Spinnbalken werden dann die Fasern aufgebracht, die den elastischen Halt des Gebildes ausmachen. Ein dritter Spinnbalken kann dazu vorgesehen sein, Fasern aufzubringen, die sich in einem späteren Arbeitsgang zum Beispiel bedrucken lassen. Ist der Träger hingegen auf der Körbchenaußenseite angeordnet ist die Ablagereihenfolge der Fasern umgekehrt.If a fiber multilayer structure is desired, for example for making brassiere baskets, and if the inside of the basket is located on the side facing the wearer, for example, first the soft fibers are laid down by a first spinning beam. In a second spin beam then the fibers are applied, which make up the elastic support of the structure. A third spin beam may be provided to apply fibers that may be printed in a later operation, for example. On the other hand, when the carrier is placed on the outside of the basket, the filing order of the fibers is reversed.

In Figur 1 ist eine Faserlegevorrichtung 1 schematisch veranschaulicht, die zur Herstellung von räumlichen, d.h. dreidimensional geformten Vliesen dient. Zu der Faserlegevorrichtung 1 gehört ein Träger 2, der mindestens eine, vorzugsweise aber mehrere, 3D-Formen 3, 4 aufweist. Diese 3D-Formen 3, 4 sind beispielsweise ungefähr halbkugelförmige oder anderweitig ausgebildete dreidimensionale Formen. Beispielswiese können die 3D-Formen 3, 4 eine dem Körbchen eines Büstenhalters entsprechende Form aufweisen, um Büstenhalter herzustellen. Die 3D-Formen können Erhebungen oder Vertiefungen sein. Sie haben zumindest stellenweise eine Oberfläche, die an der gleichen Stelle sowohl in Trägerlängsrichtung als auch in Trägerquerrichtung gekrümmt ist.In FIG. 1 a fiber-laying device 1 is schematically illustrated, which serves for the production of spatial, ie three-dimensionally shaped nonwovens. The fiber-laying device 1 includes a carrier 2, which has at least one, but preferably several, 3D-forms 3, 4. For example, these 3D shapes 3,4 are approximately hemispherical or otherwise formed three-dimensional shapes. For example, the 3D molds 3, 4 may have a shape corresponding to the cup of a brassiere to make bras. The 3D shapes can be elevations or depressions. At least in places, they have a surface which is curved at the same point both in the carrier longitudinal direction and in the transverse direction of the carrier.

Der Träger 2 besteht vorzugsweise aus einem porösen oder auch siebartigen Material. Er kann als endloses, zum Beispiel um zwei oder mehrere Rollen geschlungenes Band ausgebildet sein, an dem die 3D-Formen 3, 4 vorgesehen sind. Insoweit ist in Figur 1 lediglich ein Ausschnitt aus dem Träger 2 dargestellt. Die gegebenenfalls angetriebenen Rollen, um die der Träger 2 geschlungen ist, sind nicht weiter veranschaulicht.The carrier 2 is preferably made of a porous or sieve-like material. It can be designed as an endless belt, for example wrapped around two or more rollers, on which the 3D molds 3, 4 are provided. In that regard, is in FIG. 1 only a section of the carrier 2 shown. The optionally driven rollers around which the carrier 2 is looped are not further illustrated.

Zu der Faserlegevorrichtung 1 können außerdem ein oder mehrere Düsenbalken 5, 6, 7 gehören, die jeweils mit einer Reihe von Schmelzblasdüsen 8, 9, 10 besetzt sind. Diese dienen dazu, aus geschmolzenem Kunststoff Fasern zu extrudieren, um diese auf den Träger 2 aufzubringen. Während die Düsenbalken 5, 6, 7 vorzugsweise ortsfest angeordnet sind, wird der vorzugsweise als endloses Band ausgebildete Träger 2 vorzugsweise in der in Figur 1 durch eine Pfeil 11 veranschaulichten Trägerlängsrichtung quer zu den Düsenbalken 5, 6, 7 unter diesem vorbei bewegt.To the fiber-laying device 1 may also include one or more nozzle bars 5, 6, 7, which are each occupied by a series of melt-blowing nozzles 8, 9, 10. These serve to extrude fibers from molten plastic in order to apply them to the carrier 2. While the nozzle bars 5, 6, 7 are preferably arranged in a stationary manner, the carrier 2, which is preferably in the form of an endless belt, is preferably located in the in FIG FIG. 1 represented by an arrow 11 carrier longitudinal direction transverse to the nozzle bar 5, 6, 7 moved under this past.

Optional kann an dem Ende der von den Düsenbalken 5, 6, 7 gebildeten Reihe oder zwischen benachbarten Düsenbalken 5, 6 eine Vliesverfestigungseinrichtung 12, zum Beispiel in Gestalt eines Düsenstreifens, angeordnet sein. Diese kann dazu eingerichtet sein, einen Wasserstrahlvorhang auf den Träger 2 zu richten.Optionally, a nonwoven bonding device 12, for example in the form of a nozzle strip, may be arranged at the end of the row formed by the nozzle bars 5, 6, 7 or between adjacent nozzle bars 5, 6. This can be adapted to direct a water jet curtain on the support 2.

Alternativ können ein oder mehrere der Schmelzblasdüsen 8, 9, 10 durch Einrichtungen ersetzt sein, die dazu eingerichtet sind, vorgefertigte Fasern, beispielsweise Naturfasern, auf den Träger 2 aufzubringen. Weiter können die Düsenbalken 5, 6, 7 gleichartig oder unterschiedlich ausgebildet sein. Sie können dazu eingerichtet sein, Fasern aus gleichen oder unterschiedlichen Kunststoffen auf den Träger 2 aufzubringen. Außerdem können eine oder mehrere der Düsenstreifen 5, 6, 7 dazu eingerichtet sein, aus verschiedenen Komponenten bestehende Fasern zu erzeugen, beispielsweise Fasern mit einem Kern aus einem ersten Material und eine Hülle aus einem zweiten Material.Alternatively, one or more of the meltblowing dies 8, 9, 10 may be replaced by means adapted to apply prefabricated fibers, for example natural fibers, to the carrier 2. Further, the nozzle bars 5, 6, 7 may be formed similar or different. They may be adapted to apply fibers of the same or different plastics to the carrier 2. In addition, one or more of the nozzle strips 5, 6, 7 may be configured to produce fibers composed of different components, for example fibers having a core of a first material and a sheath of a second material.

Mit der aus Figur 1 schematisch ersichtlichen Faserlegevorrichtung kann ein dreidimensionaler Faserflor hergestellt werden, wie es in Figur 2 angedeutet ist. Der sich in Richtung des Pfeils 11 bewegende Träger 2 läuft unter den Düsenbalken 5, 6, 7 hindurch. Damit treffen zuerst die von der Schmelzblasdüse 8 abgegebenen Fasern 13, dann die von der Schmelzblasdüse 9 abgegebenen Fasern 14 und dann die von der Schmalzblasdüse 10 abgegebenen Fasern 15 auf den Träger 2 bzw. die bereits darunter liegende Faserschicht. Es bildet sich auf den hier näherungsweise halbkugelförmigen 3D-Formen 3, 4 ein Faserflor 16. Dieser kann vollkommen lose sein. Wird die Vliesverfestigungseinrichtung 12 vorgesehen und betrieben, ist der Faserflor 16 zumindest teilverfestigt. Das Anlagern der Fasern 13, 14, 15 an den Träger 2 kann durch einen von den Schmelzblasdüsen 8, 9, 10 ausgehenden Luftstrom sowie gegebenenfalls durch einen Unterdruck gefördert werden, der an die Unterseite des Trägers 2 angelegt sein kann. Der Faserflor 16 kann schichtweise aufgebaut sein. Zum Beispiel können die Fasern 13 aus einem flauschigen gut hautverträglichen Material bestehen. Die Fasern 14 können beispielsweise aus einem vorwiegend elastischen, haltgebenden und stützenden Material bestehen, während die Fasern 15 aus einem der vorigen Materialien oder auch aus einem dritten Material bestehen können, beispielsweise einem für die Außenfläche eines Büstenhalters vorgesehenen bedruckbaren, färbbaren, gefärbten oder anderweitigem Material.With the out FIG. 1 schematically apparent fiber laying device, a three-dimensional Faserflor can be produced, as in FIG. 2 is indicated. The carrier 2 moving in the direction of the arrow 11 passes under the nozzle bars 5, 6, 7. Thus, first of all, the fibers 13 discharged from the melt-blowing nozzle 8, then the fibers 14 discharged from the melt-blowing nozzle 9 and then the fibers 15 discharged from the Schmalzblasdüse 10 hit the carrier 2 or the already underlying fiber layer. It forms on the here approximately hemispherical 3D shapes 3, 4 a batt 16. This can be completely loose. If the web stabilizer 12 is provided and operated, the batt 16 is at least partially solidified. The attachment of the fibers 13, 14, 15 to the carrier 2 can be promoted by an outgoing of the melt-blowing nozzles 8, 9, 10 air flow and optionally by a negative pressure, which may be applied to the underside of the carrier 2. The batt 16 can be constructed in layers. For example, the fibers 13 may consist of a fluffy, skin-friendly material. For example, the fibers 14 may be comprised of a predominantly elastic, supportive, and supportive material, while the fibers 15 may be comprised of any of the foregoing materials, or may include a third material, such as a printable, dyeable, dyed, or otherwise provided material for the outer surface of a brassiere ,

Das gegebenenfalls vorverfestigte Faserflor wird an einer Seite fortwährend von dem sich bewegenden Träger 2 abgenommen und einer Verfestigungseinrichtung 17 zugeführt, wie sie aus Figur 3 hervorgeht. Diese kann aus einer Reihe von Düsen 18 bis 24 bestehen, die beispielsweise feine Wasserstrahlen oder Strahlen eines sonstigen gasförmigen oder flüssigen Fluids auf den Faserflor 16 richten. Die Düsen 18 bis 24 können gegebenenfalls auf lediglich einer Seite des Faserflors 16 oder auch auf beiden Seiten desselben angeordnet sein. Die auf den Faserflor 16 einwirkenden Strahlen sind in Figur 3 schematisch veranschaulicht. Sie dienen dazu, aus dem relativ losen Faserflor 16 unter Beibehaltung der ursprünglich von dem Träger 2 vorgegebenen dreidimensionalen Form ein verfestigtes filzartiges Vlies bzw. einen Vlieskörper 25 zu erzeugen.The possibly pre-consolidated fiber web is continuously removed from the moving support 2 on one side and fed to a solidifying device 17, as it is FIG. 3 evident. This may consist of a series of nozzles 18 to 24 which direct, for example, fine jets of water or jets of other gaseous or liquid fluid onto the batt 16. The nozzles 18 to 24 may optionally be arranged on only one side of the batt 16 or on both sides thereof. The rays acting on the batt 16 are in FIG. 3 illustrated schematically. They serve to produce a consolidated felt-like nonwoven or a nonwoven body 25 from the relatively loose fibrous web 16 while retaining the three-dimensional shape originally predetermined by the carrier 2.

Im vorliegenden Ausführungsbeispiel haben die Düsen 18 bis 24 eine zueinander parallele Ausrichtung. Es ist aber auch möglich, die Düsen 23 bis 24 in Anpassung an die räumliche Form des gewünschten Filzkörpers auszurichten. Weiter ist es, wie in Figur 5 angedeutet ist, möglich, den Faserflor 16 zum Verfestigen auf einem geeigneten zum Beispiel siebartigen Träger 26 zu halten.In the present embodiment, the nozzles 18 to 24 have a mutually parallel alignment. But it is also possible to align the nozzles 23 to 24 in adaptation to the spatial shape of the desired felt body. Continue is it, as in FIG. 5 indicated, it is possible to hold the batt 16 to solidify on a suitable, for example sieve-like carrier 26.

Figur 4 veranschaulicht einen Ausschnitt aus einem so erhaltenen Vlieskörper 25. Der Vlieskörper 25 ist, wie ersichtlich, mehrschichtig, hier zweischichtig, aufgebaut. Er besteht aus einer ersten Faserschicht 26, beispielsweise bestehend aus weichen gekräuselten Fasern und einer außen liegenden zweiten Faserschicht 27, bestehend aus Fasern aus einem anderen Material. Die beiden Faserschichten 26, 27 sind innig miteinander verbunden und in sich verfilzt bzw. verfestigt. Sie folgen der von dem Träger 2 ursprünglich vorgegebenen Form. Aus dem derartig hergestellten Vlieskörper 25 lassen sich die gewünschten 3D-Filzkörper, beispielsweise Kleidungsstücke, beispielsweise Büstenhalterrohlinge, ausschneiden. Diese können dann weiteren Bearbeitungsschritten zugeführt werden, in denen sie beispielsweise besäumt, bedruckt und/oder konfektioniert werden. FIG. 4 illustrates a section of a thus obtained nonwoven body 25. The nonwoven body 25 is, as can be seen, multi-layered, here two-layered constructed. It consists of a first fiber layer 26, for example consisting of soft crimped fibers and an outer second fiber layer 27, consisting of fibers of a different material. The two fiber layers 26, 27 are intimately interconnected and entangled or solidified. They follow the form originally given by the carrier 2. From the nonwoven body 25 produced in this way, the desired 3D felt bodies, for example garments, for example brassiere blanks, can be cut out. These can then be supplied to further processing steps in which they are, for example, trimmed, printed and / or assembled.

Das Verfahren ist vorstehend an einem Träger 2 erläutert worden, der die Hohlform, d.h. die Innenseite des herzustellenden Filzkörpers festlegt. Wie in Figur 6 veranschaulicht, kann der Träger 2' jedoch auch derart angeordnet werden, das er die konvexe Außenform des herzustellenden Körpers definiert. Wiederum sind ein oder mehrere Düsenbalken 5, 6, 7 mit Schmelzblasdüsen 8, 9, 10 oder anderen zur Abgabe von Fasern eingerichteten Einrichtungen vorgesehen. An einer geeigneten Stelle, zum Beispiel zwischen den Düsenbalken 6, 7 oder auch an einem Ende der von den Düsenbalken 5, 6, 7 gebildeten Reihe, ist die optionale Vliesverfestigungseinrichtung 12 vorgesehen. Außerdem können weitere derartige Vliesverf,estigungsvorrichtungen zwischen den anderen Düsenbalken 5, 6 vorgesehen sein. Die Fasern 13, 14, 15 werden, wie vorstehend beschrieben, auf den Träger 2' aufgebracht und bilden einen relativ losen gegebenenfalls vorverfestigten Faserflor 16. Dieser kann aus einem einzigen Material oder, wie es bevorzugt wird und in Figur 6 dargestellt ist, mehrschichtig aufgebaut sein. Der vorverfestigte Faserflor kann dann wiederum einer Verfestigungseinrichtung 17 zugeführt werden wie es in Figur 3 schon dargestellt ist.The method has been explained above on a support 2, which defines the hollow shape, ie the inside of the felt body to be produced. As in FIG. 6 however, the support 2 'may be arranged so as to define the convex outer shape of the body to be manufactured. Again, one or more nozzle bars 5, 6, 7 are provided with meltblowing dies 8, 9, 10 or other means for delivering fibers. At an appropriate location, for example between the nozzle bars 6, 7 or also at one end of the row formed by the nozzle bars 5, 6, 7, the optional web bonding device 12 is provided. In addition, other such Vliesverf, estigungsvorrichtungen between the other nozzle bars 5, 6 may be provided. The fibers 13, 14, 15 are, as described above, on the Carrier 2 'applied and form a relatively loose possibly pre-consolidated fibrous web 16. This can be made of a single material or, as it is preferred and in FIG. 6 is shown to be multi-layered. The pre-consolidated fiber web can then be fed to a solidifying device 17 again as in FIG. 3 already shown.

Anstelle des dargestellten Wasserstrahlverfestigungsverfahrens oder zusätzlich zu demselben können auch andere Bearbeitungsschritte vorgenommen werden, wie beispielsweise Thermobonden, Imprägnieren oder dergleichen.Instead of the illustrated Wasserstrahlverfestigungsverfahrens or in addition to the same, other processing steps can be made, such as thermal bonding, impregnation or the like.

Bei dem erfindungsgemäßen Verfahren zur Herstellung von räumlichen Gegenständen aus einem Vlies bzw. Filz werden Fasern auf einer Form abgelegt, die vorzugsweise luftdurchlässig ist. Die Fasern können durch Unterdruck unter der Form an diese angezogen werden. Die Form hat vorzugsweise mehrere räumliche Strukturen, die die Form des sich bildenden Faserflors bestimmen und zumindest angenähert der gewünschten Endform entsprechen. Durch das nachfolgende Verfestigen des so gewonnen geformten Faserflors wird ein räumlich dreidimensionaler Filzgegenstand erreicht. Bei diesem Verfahren werden nachträgliche Verformschritte überflüssig oder auf ein geringes Maß reduziert, so dass das herzustellende Material keinen wesentlichen Verzug erfährt.In the method according to the invention for the production of spatial objects from a fleece or felt, fibers are deposited on a mold, which is preferably permeable to air. The fibers can be attracted to them by vacuum under the mold. The mold preferably has a plurality of spatial structures that determine the shape of the forming batt and at least approximately correspond to the desired final shape. By subsequently solidifying the thus obtained formed batt, a spatially three-dimensional felt article is achieved. In this method subsequent deformation steps are superfluous or reduced to a low level, so that the material to be produced undergoes no significant delay.
