Die Anordnung erster und zweiter und ggf. weiterer gerader Bandabschnitte mit einer entsprechenden Zahl von drei oder mehr Umlenkstellen an der Bandumlenkung hat den Vorteil, dass der Faserflor an den kritischen Stellen besser geführt werden kann. Die drei oder mehr Umlenkstellen reduzieren gegenüber dem Stand der Technik die Umlenkwinkel, was ebenfalls für die Führung und den Halt des Flors von Vorteil ist. Die Band- und Florumlenkung kann in mehreren Schritten allmählich und damit schonender erfolgen. Der letzte gerade Bandabschnitt am Ende der Bandumlenkung kann bereits eine Neigung in die der Zuführrichtung entgegengesetzte Richtung haben, wobei in diesem Bandabschnitt der Flor beidseitig im Klemmschluss von den Legebändern geführt sein kann. In diesem Bandabschnitt kann er verfestigt werden, so dass er die letzte Umlenkstelle trotz einer dort nur einseitigen Florführung sicher und auch mit hoher Durchlaufgeschwindigkeit passieren kann. Fliehkraftbedingte Ablösungen des Faserflors von einem nur einseitig führenden Legeband oder Strukturänderungen des Faserflors an solchen Umlenkstellen können mit der erfindungsgemäßen Bandumlenkung vermieden werden.The arrangement of first and second and optionally further straight band sections with a corresponding number of three or more deflection points on the band deflection has the advantage that the batt at the critical points better can be performed. The three or more deflection points reduce over the prior art, the deflection angle, which is also beneficial for the guidance and the hold of the pile. The band and Florumlenkung can be done gradually and thus gently in several steps. The last straight band section at the end of the band deflection may already have an inclination in the direction opposite to the feed direction, wherein in this band section the pile can be guided on both sides in the terminal closure of the guide belts. In this band section, it can be solidified so that it can pass safely through the last deflection point despite a there only one-sided pile guide and also with high throughput speed. Fliehkraftbedingte detachments of the batt of only one-sided leading band or structural changes of the batt at such deflection can be avoided with the band deflection invention.
Der beanspruchte Vliesleger kann für sehr hohe Band- und Florlaufgeschwindigkeiten ausgelegt sein. Hierfür ist eine Ausbildung als gleichläufiger Leger mit gleichsinnig bewegten Hauptwagen von Vorteil. Der Flor kann vom Oberwagen, dem Legewagen auf einem direkten und geraden Weg ohne weitere Umlenkungen zugeführt werden und vom Legewagen auf eine Abzugeinrichtung abgelegt werden.The claimed nonwoven can be designed for very high belt speeds and web speeds. For this purpose, training as gleichläufiger Leger with the same direction moving main car advantage. The pile can be supplied by the superstructure, the laying carriage on a direct and straight path without further deflections and stored by the carriage on a deduction device.
Der Vliesleger kann außerdem eine Spanneinrichtung bzw. Bandlängenausgleichseinrichtung aufweisen, die eine Entkoppelung der Hauptwagen und deren Kinematik ermöglicht. Hierdurch kann das Flächengewicht des abgelegten Vlieses über die Legebreite und/oder über die Vlieslänge beeinflusst und ggf. verändert werden. Außerdem kann der Vliesleger eine Pufferfunktion für den Ausgleich schwankender Einlaufgeschwindigkeiten des Faserflors haben.The nonwoven layer can also have a tensioning device or band length compensation device, which enables decoupling of the main carriage and its kinematics. As a result, the weight per unit area of the deposited nonwoven can be influenced and if necessary changed over the laying width and / or over the length of fleece. In addition, the nonwoven may have a buffering function to compensate for fluctuating shrinkage speeds of the batt.

Die Erfindung betrifft einen Vliesleger (1) sowie ein Vlieslegeverfahren. Die Erfindung betrifft auch eine Faserbehandlungsanlage mit einem Vliesleger (1) und weiteren Anlagenkomponenten.The invention relates to a nonwoven layer (1) and a nonwoven laying method. The invention also relates to a fiber treatment plant with a nonwoven layer (1) and other plant components.
Der Vliesleger (1) dient dazu, einen zugeführten Faserflor (9) zu einem mehrlagigen Vlies (10) abzutäfeln. Der Vliesleger (1) weist hierfür im Ausführungsbeispiel von
Die beiden in getrennten Schleifenbahnen geführten Legebänder (6,7) kommen am Oberwagen (2) aus unterschiedlichen Richtungen zusammen, werden dort über eine nachfolgend beschriebene Bandumlenkung (12) geführt und treten am Oberwagen (2) in Parallellage aus, wobei sie zwischen sich den Faserflor (9) aufnehmen und beidseitig im Klemmschluss führen. Im gezeigten Ausführungsbeispiel eines gleichsinnigen Vlieslegers (1) wird von diesem parallelen Bandabschnitt der Faserflor (9) direkt in einer geraden Bahn an den Legewagen (3) übergeben. Am Legewagen (3) treten die Legebänder (6,7) wieder auseinander und werden nach entgegengesetzten Richtungen weggeführt, wobei der freigegebene Faserflor (9) nach unten auf die Abzugeinrichtung (8) austritt und dort abgelegt wird. Der Legewagen (7) führt hierfür reversierende Fahrbewegungen in Querrichtung zur Abzugeinrichtung (8) auf, welche eine mit der Legewagenbewegung vorzugsweise gekoppelte Vorwärtsbewegung ausführt und das in schuppenförmig abgetäfelte Vlies (10) abtransportiert.The two guided in separate loop paths strips (6,7) come together on the superstructure (2) from different directions, where they are guided over a band deflection (12) described below and emerge from the superstructure (2) in a parallel position, between them the Take up the batt (9) and both sides in the terminal lead. In the exemplary embodiment of a co-directional fleece layer (1), the fleece (9) is transferred directly from the parallel strip section to the laying carriage (3) in a straight path. At the laying carriage (3), the laying belts (6, 7) come apart again and are led away in opposite directions, wherein the released fiber web (9) exits downwards onto the removal device (8) and is deposited there. The laying carriage (7) performs this reversing driving movements in the transverse direction to the removal device (8), which performs a preferably coupled with the laying carriage movement forward movement and transported away in scale-like padded fleece (10).
Die Hauptwagen (2,3) sind mittels Laufwerken (31) an einer Schienenführung im Gestell des Vlieslegers (1) parallel zueinander beweglich gelagert und geführt. Sie haben dabei jeweils einen eigenen und eigenständig steuerbaren Antrieb (nicht dargestellt) für ihre Fahrbewegung. Beim gezeigten gleichsinnigen Leger bewegen sich die Hauptwagen (2,3) in die gleiche Fahrtrichtung, wobei der Oberwagen (2) im Vergleich zum Legewagen (3) doppelte Wege und eine doppelte Geschwindigkeit hat.The main cars (2, 3) are mounted and guided in parallel to one another by means of drives (31) on a rail guide in the frame of the nonwoven layer (1). They each have their own and independently controllable drive (not shown) for their driving movement. When shown in the same direction Leger move the main car (2,3) in the same direction, the uppercarriage (2) compared to the laying carriage (3) has double paths and a double speed.
Die Fahrbewegungen der Hauptwagen (2,3) können voneinander entkoppelt sein, so dass durch Bewegungsunterschiede die Schlaufenlänge der zwischen den Hauptwagen (2,3) parallel geführten Legebänder (6,7) verändert und dadurch ein Florspeicher gebildet werden kann. Die Legebänder (6,7) können ebenfalls eigenständige Antriebe aufweisen, die sie in eine gesteuerte Umlaufbewegung versetzen. Durch eine solche Konfiguration ist es möglich, die Austrittsgeschwindigkeit des Faserflors (9) am Legewagen (3) zu beeinflussen und insbesondere von der Fahrgeschwindigkeit des Legewagens (3) zu entkoppeln. Hierüber kann die Florablage auf der Abzugeinrichtung (8) und das Flächengewicht des Vlieses (10) beeinflusst und über die Legebreite des hin- und herfahrenden Legewagens (3) verändert werden. Damit lassen sich einerseits Randverdickungen des Vlieses (10) vermeiden und andererseits bewusste Profilierungen in Quer- und/oder Längsrichtung des Vlieses (10) bilden. Mit solchen Profilierungen kann das verfestigte Endprodukt eine gewünschte Flächengewichtsverteilung erhalten oder es kann Fehlerkompensation von Flor- oder Verfestigungsfehlern betrieben werden. Außerdem ist es möglich, durch die Hauptwagenentkoppelung und die Spanneinrichtung (4) Geschwindigkeitsschwankungen im zugeführten Faserflor (9) zu kompensieren und eine Pufferwirkung zu entfalten.The movements of the main car (2,3) may be decoupled from each other, so that changes in movement differences, the loop length of the main carriage (2,3) parallel guided bands (6,7) and thereby a pile store can be formed. The bands (6,7) may also have independent drives that put them in a controlled orbital motion. Such a configuration makes it possible to influence the exit speed of the fibrous web (9) on the laying carriage (3) and, in particular, to decouple it from the traveling speed of the laying carriage (3). This can affect the pile tray on the removal device (8) and the weight per unit area of the fleece (10) and be changed over the laying width of the reciprocating laying carriage (3). On the one hand, this makes it possible to avoid edge thickening of the fleece (10) and, on the other hand, to form conscious profilings in the transverse and / or longitudinal direction of the fleece (10). With such profilings, the solidified end product can receive a desired basis weight distribution or error compensation of pile or consolidation errors can be operated. In addition, it is possible to compensate for speed fluctuations in the supplied fiber web (9) by the main carriage decoupling and the tensioning device (4) and to develop a buffering effect.
Mit dieser vorbeschriebenen Grundkonzeption kann der Vliesleger (1) in unterschiedlicher Weise ausgebildet sein, z.B. entsprechend der
Das andere Legeband (7) wird nachfolgend als Gegenband bezeichnet. Beide Legebänder (6,7) werden in einer im Wesentlichen horizontalen Ausrichtung dem Oberwagen (2) und der Bandumlenkung (12) zugeführt. Das Zuführband (6) wird an der Bandumlenkung (12) aus seiner Zuführrichtung (11) in die Gegenrichtung um ca. 180° nach unten zu einer Auslassstelle (33) am Oberwagen umgelenkt. Hier treten beide Legebänder (6,7) in eng benachbarter Parallelage aus und bilden im Sandwich mit dem Faserflor (9) einen beidseitigen Florführungsbereich (34).The other laying belt (7) is referred to below as the counter belt. Both laying belts (6, 7) are fed in a substantially horizontal orientation to the superstructure (2) and the belt deflection (12). The feed belt (6) is at the band deflection (12) from its feed direction (11) deflected in the opposite direction by about 180 ° down to an outlet point (33) on the superstructure. Here, both guide strips (6,7) emerge in closely adjacent parallel positions and form a two-sided pile guide region (34) in the sandwich with the batt (9).
In der gezeigten Variante sind das Obertrum (13) und das Untertrum (14) des Zuführbandes (6) parallel ausgerichtet, wobei die Auslaufhöhe des Oberwagens (2) und die Einlaufhöhe des Legewagens (3) gleich sind. Hieraus resultiert ein Umlenkwinkel von 180°. Wenn die besagte Auslauf- und Einlaufhöhe unterschiedlich sind, kann das Untertrum (14) eine Neigung gegen die Horizontale haben, so dass der Umlenkwinkel von 180° geringfügig abweichen kann. Eine Winkelabweichung kann auch aus anderen Gründen eintreten, z.B. wenn das Obertrum (13) eine Schräglage hat.In the variant shown, the upper strand (13) and the lower strand (14) of the feed belt (6) are aligned in parallel, wherein the outlet height of the upper carriage (2) and the inlet height of the laying carriage (3) are the same. This results in a deflection angle of 180 °. If the said outlet and inlet heights are different, the lower run (14) may have an inclination to the horizontal, so that the deflection angle of 180 ° may differ slightly. Angular deviation may also occur for other reasons, e.g. when the upper run (13) has a tilt.
Das Gegenband (7) wird an der Bandumlenkung zwar ebenfalls umgelenkt, wobei die Eintritts- und Austrittsrichtung des Gegenbands (7) am Oberwagen (2) gleichgerichtet und insbesondere horizontal sein kann. Mit der Bandumlenkung (12) wird dazwischen ein Höhenversatz des Gegenbands (7) zwischen Einlass- und Auslassstelle (32,33) bewirkt.Although the counter-belt (7) is likewise deflected at the belt deflection, the entry and exit direction of the opposing belt (7) on the superstructure (2) can be rectified and, in particular, horizontal. With the band deflection (12) is effected in between a height offset of the opposite band (7) between the inlet and outlet point (32,33).
Beide oben eintretenden Legebänder (6,7) werden an der Bandumlenkung (12) nach unten umgelenkt und treten am Oberwagen (2) in einer tieferen Lage wieder aus, die in der vorerwähnten Weise vorzugsweise die gleiche Höhe wie die Einlaufstelle am Legewagen (3) hat.Both above entering levers (6,7) are deflected at the band deflection (12) down and emerge on the upper carriage (2) in a lower position again, in the aforementioned manner preferably the same height as the inlet point on the laying carriage (3) Has.

Die drei Umlenkstellen (15,16,17) bzw. Umlenkollen sind mit Abstand übereinander angeordnet, wobei die mittlere Umlenkstelle (16) in Zuführrichtung (11) weiter vorn als die beiden anderen Umlenkstellen (15,17) liegt. Hierdurch wird zwischen der oberen und der mittleren Umlenkstelle bzw. Umlenkrolle (15,16) ein erster gerader Bandabschnitt (22) und zwischen der mittleren (16) und der unteren Umlenkstelle bzw. Umlenkrolle (17) ein zweiter gerader Bandabschnitt (23) des Zuführbands (6) gebildet. Der in Zuführrichtung (11) erste Bandabschnitt (22) ist in Zuführrichtung (11) schräg abwärts gerichtet. Der zweite Bandabschnitt (23) ist entgegen der Zuführrichtung (11) schräg abwärts gerichtet. Falls die Bandumlenkung (12) mehr als drei Umlenkstellen für das Zuführband (6) hat, ist der Bandabschnitt (23) der letzte Bandabschnitt vor der Auslassstelle (33) des Oberwagens (2).The three deflection points (15, 16, 17) or deflection rollers are arranged at a distance one above the other, wherein the middle deflection point (16) in the feed direction (11) lies further forward than the two other deflection points (15, 17). In this way, between the upper and middle deflection point or deflection roller (15, 16), a first straight belt section (22) and between the middle (16) and lower deflection point or deflection roller (17) a second straight belt section (23) of the feed belt (6) formed. The in the feed direction (11) first band portion (22) is directed in the feed direction (11) obliquely downward. The second band section (23) is directed counter to the feed direction (11) obliquely downward. If the band deflection (12) has more than three deflection points for the feed belt (6), the band section (23) is the last band section in front of the outlet point (33) of the upper carriage (2).
Das Zuführband (6) hat an den gezeigten drei Umlenkstellen (15,16,17) jeweils einen Umlenkwinkel α, β, γ, der weniger als 90° beträgt. In der Summe ergeben die Winkel α, β, γ den Gesamt-Umlenkungswinkel von z.B. 180°.The feed belt (6) has at the shown three deflection points (15,16,17) each have a deflection angle α, β, γ, which is less than 90 °. In sum, the angles α, β, γ give the total deflection angle of e.g. 180 °.
Im gezeigten Ausführungsbeispiel ist der erste Umlenkwinkel α an der ersten Umlenkstelle bzw. Umlenkrolle (15) und auch der letzte, insbesondere dritte Umlenkwinkel γ an der letzten oder dritten Umlenkstelle (17) jeweils größer als der Umlenkwinkel γ an der mittleren Umlenkstelle (16). Der erste Umlenkwinkel α kann zwischen 55° und 70°, vorzugsweise ca. 63°, betragen. Der zweite kleinere Umlenkwinkel β kann zwischen 40° und 55°, bevorzugt ca. 46°, betragen. Der dritte und z.B. letzte Umlenkwinkel γ kann zwischen 65° und 75° liegen und beträgt bevorzugt ca. 71°.In the illustrated embodiment, the first deflection angle α at the first deflection point or deflection roller (15) and also the last, in particular third deflection angle γ at the last or third deflection point (17) are each greater than the deflection angle γ at the middle one Deflection point (16). The first deflection angle α can be between 55 ° and 70 °, preferably about 63 °. The second smaller deflection angle β can be between 40 ° and 55 °, preferably about 46 °. The third and eg last deflection angle γ can be between 65 ° and 75 ° and is preferably about 71 °.
Die vorgenannten Umlenkwinkel α, β, γ, können in der Größe und Zuordnung variieren. In einer anderen Ausführungsform kann z.B. die erste Umlenkstelle bzw. Umlenkrolle (15) am Oberwagen (2) gegen die Zuführrichtung (11) horizontal verschoben sein, wobei die beiden anderen Umlenkstellen bzw. Umlenkrollen (16,17) ihre Anordnung und Ausbildung behalten. Hierdurch wird der erste Umlenkwinkel α kleiner und der zweite Umlenkwinkel β größer als in
Die Bandumlenkung (12) weist für das andere Gegenband (7) ebenfalls drei oder mehr Umlenkrollen (18 bis 21) auf. Hierbei sind drei Umlenkrollen (18,19,20) mit Abstand übereinander angeordnet. In Zulaufrichtung des Gegenband (7) zum Oberwagen (2) gesehen liegt die erste Umlenkrolle (18) dabei vor der mittleren Umlenkrolle (19) und diese wieder vor der unteren Umlenkrolle (20). Zwischen der ersten und der zweiten bzw. mittleren Umlenkrolle (18,19) wird ein erster gerader Bandabschnitt (24) und zwischen der zweiten bzw. mittleren Umlenkrolle (19) und der unteren und/oder dritten Umlenkrolle (20) ein zweiter gerader Bandabschnitt (25) gebildet. Auch diese geraden Bandabschnitte (24,25) haben unterschiedliche Ausrichtungen.The band deflection (12) also has three or more deflection rollers (18 to 21) for the other counter belt (7). Here are three pulleys (18,19,20) arranged at a distance one above the other. Seen in the direction of feed of the counter belt (7) to the superstructure (2), the first deflection roller (18) is located in front of the middle deflection roller (19) and this again in front of the lower deflection roller (20). Between the first and the second or middle deflection roller (18, 19) a first straight band section (24) and between the second or middle deflection roller (19) and the lower and / or third deflection roller (20) a second straight band section (FIG. 25) is formed. These straight band sections (24, 25) also have different orientations.
Für das Gegenband (7) ist außerdem noch eine vierte Umlenkrolle (21) neben der unteren Umlenkrolle (20) vorgesehen, mit der das Gegenband (7) um mehr als 180° umgelenkt wird und dann am Auslass (33) des Oberwagens (2) eine parallele und z.B. horizontale Lage zum Zuführband (6) und dessen Untertrum (14) einnimmt. Eine unterhalb der Umlenkrollen (17, 20) angeordnete Stützrolle (27) stützt das umgelenkte Gegenband (7). Sie kann verstellbar sein, um die Bandhöhe und den Abstand zum Zuführband (6) einzustellen und ggf. an unterschiedliche Flordicken anzupassen.For the counter belt (7) is also still a fourth guide roller (21) next to the lower guide roller (20) provided with which the counter-belt (7) is deflected by more than 180 ° and then at the outlet (33) of the upper carriage (2) a parallel and eg horizontal position to the feed belt (6) and its lower run (14) occupies. A below the pulleys (17, 20) arranged support roller (27) supports the deflected counter-belt (7). It can be adjustable in order to adjust the band height and the distance to the feed belt (6) and, if necessary, to adapt to different pile thicknesses.
Am Auslass (33) des Oberwagens (2) ist das Gegenband (7) unten angeordnet und trägt den Faserflor (9), wobei das Zuführband (6) darüber angeordnet ist und den Faserflor (9) von oben abdeckt.At the outlet (33) of the upper carriage (2), the counter belt (7) is arranged below and carries the batt (9), wherein the feed belt (6) is arranged above it and covers the batt (9) from above.

Die zweiten oder letzten geraden Bandabschnitte (23,25) beider Legebänder (6,7) verlaufen eng benachbart und sind im Wesentlichen gleich gerichtet, wobei ihre Ausrichtung eine Richtungskomponente entgegen der Zuführrichtung (11) hat. Die zweiten oder letzten geraden Bandschnitte (23,25) bilden dabei zwischen sich einen engen Spalt, in dem der Faserflor (9) aufgenommen und ggf. mit Klemmschluss beidseitig geführt ist. Die besagten Bandabschnitte (23,25) können dabei parallel zueinander verlaufen. Sie können zum Zwecke einer Florkompaktierung auch mit einem spitzen Winkel konisch aufeinander zu verlaufen und dadurch einen in Florlaufrichtung sich verengenden Spalt bilden. Die Form und Größe des Spalts kann eingestellt und verändert werden.The second or last straight strip sections (23, 25) of both guide belts (6, 7) run closely adjacent to one another and are oriented essentially identically, their orientation having a direction component opposite to the feed direction (11). The second or last straight band sections (23, 25) form a narrow gap between them, in which the fibrous web (9) is received and possibly guided on both sides with a clamping connection. The said band sections (23, 25) can run parallel to one another. You can for the purpose of a Florkkompaktierung with an acute angle tapered towards each other and thereby a narrowing in the direction of flow direction gap form. The shape and size of the gap can be adjusted and changed.

Der zweite Führungsabschnitt (30) bildet einen Klemmabschnitt zwischen den zweiten geraden Bandabschnitten (23,25), zwischen denen der Faserflor (9) im Klemmschluss beidseitig geführt ist. Der Klemmbereich (30) ist zur Auslassstelle (33) gerichtet und endet kurz davor. Am Ende des Klemmbereichs (30) wird die beidseitige Führung wieder aufgehoben, wobei der ggf. kompaktierte und zusätzlich stabilisierte Faserflor (9) an der dritten Umlenkstelle (17) wieder unter einseitiger Führung am Zuführband (6) moderat um den Winkel γ umgelenkt wird und dann in den auslassseitigen (33) beidseitigen Führungsbereich (34) zwischen den erneut zusammengeführten Legebändern (6,7) eintritt. Durch die Schräglage des Klemmbereichs (30) und der geraden Bandabschnitte (23,25) hat der Faserflor (9) bereits eine Richtungskomponente entgegen der Zuführrichtung (11) und in Weiterführrichtung zum Legewagen (3). Auch an dieser Umlenkstelle (17) löst es sich somit trotz einseitiger Führung nicht vom tragenden Zuführband (6). Dies ist auch bei hohen Laufgeschwindigkeiten und entsprechend hohen Fliehkräften der Fall.The second guide section (30) forms a clamping section between the second straight strip sections (23, 25), between which the fiber web (9) is guided on both sides in the terminal closure. The clamping area (30) is directed to the outlet point (33) and ends shortly before. At the end of the clamping region (30), the two-sided guide is canceled again, wherein the optionally compacted and additionally stabilized fiber web (9) at the third deflection point (17) again under one-sided guidance on the feed belt (6) moderately deflected by the angle γ and then enters the outlet side (33) on both sides guide region (34) between the rejoined guide belts (6,7). Due to the inclined position of the clamping region (30) and the straight belt sections (23, 25), the fiber web (9) already has a directional component counter to the feed direction (11) and in the direction of advancing to the laying carriage (3). Even at this deflection point (17) it thus does not detach from the load-bearing feed belt (6) despite one-sided guidance. This is the case even at high speeds and correspondingly high centrifugal forces.
Dem Vliesleger (1) können an der Eingangsseite (35) eine oder mehrere Anlagenkomponenten vorgeschaltet sein. Dies kann z.B. eine Florbildungseinrichtung, insbesondere eine Karde oder eine Krempel, sein. Außerdem kann eine Streck- oder Staucheinrichtung, ein Florspeicher oder dergleichen andere Anlagenkomponente vorgeschaltet sein. Die genannten Anlagenkomponenten sind der Übersicht halber nicht dargestellt.The nonwoven layer (1) can be preceded on the input side (35) one or more system components. This may be, for example, a pile forming device, in particular a card or a carding machine. In addition, a stretching or compression device, a pile store or the like may be connected upstream of other system components. The mentioned system components are not for the sake of clarity shown.
Auf der Ausgangsseite des Vlieslegers (1) und der Abgabestelle der Abzugeinrichtung (8) können ebenfalls ein oder mehrere Anlagenkomponenten nachgeschaltet sein. Dies kann eine Vliesverfestigungseinrichtung sein, z.B. eine einstufige oder mehrstufige Nadelmaschine, eine Wasserstrahlverfestigungsanlage, eine thermische Verfestigungseinrichtung oder dergleichen. Desgleichen kann auch ein Ausgleichsband zur Pufferung und Kompensation schwankender Vliesabgabegeschwindigkeiten zwischen Vliesleger (1) und Verfestigungseinrichtung, insbesondere Nadelmaschine, geschaltet sein. Auch diese nachgeschalteten Anlagekomponenten sind der Übersicht halber nicht dargestellt.On the output side of the web laying machine (1) and the delivery point of the discharge device (8) can also be followed by one or more system components. This may be a web stabilizer, e.g. a single-stage or multi-stage needling machine, a hydroentangling plant, a thermal consolidation device or the like. Likewise, a compensating belt for buffering and compensating fluctuating nonwoven delivery speeds between the nonwoven layering machine (1) and the solidifying device, in particular the needling machine, can also be connected. These downstream system components are not shown for clarity.
Abwandlungen der gezeigten und beschriebenen Ausführungsformen sind in verschiedener Weise möglich. Die Zahl der Umlenkstellen (15,16,17) des Zuführbands (6) kann größer als drei sein und kann z.B. vier oder fünf betragen, wobei sich die Zahl und Ausrichtung der geraden Bandabschnitte (22,23) entsprechend erhöht. Auch die Größe und Verteilung der Umlenkwinkel kann sich dabei ändern. Die Umlenkstellen (18,19,20) des Gegenbands (7) können entsprechend angepasst sein. Die Florführung (28) kann dabei ebenfalls eine größere Abschnittszahl erhalten, wobei die Zahl der offenen Führungsabschnitte (29) und/oder der Klemmabschnitte (30) erhöht werden kann.Variations of the embodiments shown and described are possible in various ways. The number of deflection points (15, 16, 17) of the feed belt (6) may be greater than three and may be e.g. four or five, with the number and orientation of the straight band sections (22,23) increases accordingly. The size and distribution of the deflection can change. The deflection points (18,19,20) of the opposing belt (7) can be adjusted accordingly. The pile guide (28) can also receive a larger number of sections, wherein the number of open guide sections (29) and / or the clamping sections (30) can be increased.
Der Vliesleger (1) kann z.B. als gegenläufiger Leger ausgebildet sein, bei dem sich die Hauptwagen (2,3) in entgegengesetzten Richtungen bewegen und die im Führungsbereich (34) parallel laufenden Legebänder (6,7) zwischen den beiden Hauptwagen (2,3) über eine gestellfeste Umlenkung, z.B. eine Umlenkwalze, geführt sind. Ferner kann die Spanneinrichtung (4) entfallen oder in anderer Weise ausgebildet sein, wobei sie z.B. nur einen einzelnen Hilfs- oder Spannwagen aufweist. Ferner kann die Führung der Legebänder (6,7) in anderer Weise ausgebildet sein, wobei z.B. ein oder mehrere zusätzliche Stützwagen angeordnet sind. Das Gegenband (7) kann zur Bildung einer geschlossenen Florzuführung bis zur Eingangsseite des Vliesleger (1) verlegt sein und den Faserflor (9) auf dem Zuführband (6) abdecken. Solche Abwandlungen der Bauform des gezeigten Vlieslegers (1) können z.B. gemäß der
Die Legebänder (6,7) bestehen im gezeigten Ausführungsbeispiel aus zugfesten und biegeelastischen Kunststoffbahnen. Sie können alternativ aus anderen Materialien bestehen und z.B. als Ketten- oder Lattenbänder ausgebildet sein. Variationen sind auch hinsichtlich der Antriebstechnik möglich. Die Hauptwagen (2,3) können einen gemeinsamen Antrieb für ihre Fahrbewegungen aufweisen und können untereinander mechanisch durch ein Seil oder dergleichen gekoppelt sein.The laying belts (6, 7) in the illustrated embodiment consist of tensile and flexurally elastic plastic webs. They may alternatively consist of other materials and e.g. be designed as a chain or slat bands. Variations are also possible with regard to drive technology. The main car (2,3) may have a common drive for their driving movements and may be mechanically coupled to each other by a rope or the like.
Der Vliesleger (1) weist eine bevorzugt programmierbare Steuerung (nicht dargestellt) auf, an die die verschiedenen Antriebe der Hauptwagen (2,3), der Legebänder (6,7) und der Abzugeinrichtung (8) sowie evtl. weiterer Komponenten, z.B. einer im Einlaufbereich angeordneten Streckeinrichtung, angeschlossen sind. Diese Steuerung kann in eine übergeordnete Anlagensteuerung angebunden oder in diese integriert sein.The fleece laying machine (1) has a preferably programmable controller (not shown) to which the various drives of the main carriage (2, 3), the laying belts (6, 7) and the removal device (8) and possibly further components, e.g. a arranged in the inlet region stretching device are connected. This control can be connected to a higher-level system control or integrated into it.
Eine Bandumlenkung (12) der gezeigten Art mit mehreren Umlenkstellen für mindestens ein Legeband (6,7) kann auch an anderen Stellen eines Vlieslegers (1) oder Kreuzlegers vorhanden sein, z.B. am Legewagen (3) oder an einer stationären 180°-Bandumlenkung im Gestell des Vlieslegers (1) .A band deflection (12) of the type shown with several deflection points for at least one laying belt (6,7) can also be present at other locations of a fleece layer (1) or stacker, for example on the laying carriage (3) or on a stationary 180 ° band deflection in the Frame of the fleece layer (1).
