Abstract

A pile-detecting apparatus is used in a machine wherein a pile fabric is deflected over a smooth surface of a roll to detect the edge between the pile-free portion of the fabric and the portion with the pile, which edge runs parallel to the displacement direction of the fabric over the roll. The apparatus has a support plate, a frame carrying the plate, a plurality of rollers mounted on the frame and riding on the surface of the deflecting roll, and at least one light source on the plate for generating light beams and directing same tangentially of the surface. Respective detectors on the plate receive the respective light beams.

Description

Die Erfindung betrifft eine Vorrichtung zum seitlichen Abtasten von florlosen Zonen an Gewebebahnen, insbesondere Frotteware, an einer Textilmaschine, bei der die Gewebebahn im Bereich der Abtastvorrichtung um eine Umlenkrolle läuft und das Abtasten der florlosen Zone mittels Fotodetektoren, bestehend aus Sender und Empfänger, erfolgt, die auf einem Rahmen befestigt sind, wobei die Abtaststrahlen tangential zur Umlenkrolle und damit zur Gewebebahn an deren Umlenkstelle gerichtet sind.The invention relates to a device for the lateral scanning of floreless zones on fabric webs, in particular terry cloth, on a textile machine, in which the fabric web runs around a deflection roller in the area of the scanning device and the floreless zone is scanned by means of photo detectors consisting of transmitter and receiver. which are attached to a frame, the scanning beams being directed tangentially to the deflection roller and thus to the fabric web at its deflection point.

Bei einer Verarbeitungsmaschine dieser Art ist es erforderlich, genau festzustellen, an welchen Stellen die florlose Zone und/oder die Florzone liegt. Dies ist während des Ablaufs der maschinellen Bearbeitung erforderlich, damit die Ware mit hoher Geschwindigkeit lagegerecht durch die Bearbeitungsmaschine hindurchgeführt werden kann.With a processing machine of this type, it is necessary to determine exactly at which points the floreless zone and / or the flor zone is located. This is necessary during the course of the machining, so that the goods can be guided through the processing machine at a high speed.

Aus der DE 89 07 659 U1 ist eine solche Vorrichtung bekannt. Obwohl diese bekannte Vorrichtung im allgemeinen zufriedenstellend arbeitet, hat sich ergeben, daß bei langen Umlenkrollen infolge deren Durchbiegung Ungenauigkeiten entstehen können, die ihre Ursache darin haben, daß der Abstand des die Fotodetektoren tragenden Rahmens gegenüber der Umlenkrolle über deren Länge nicht konstant bleibt. Die bekannte Vorrichtung hat ein oder mehrere Sender (Lichtquellen oder dergleichen), deren Strahlen tangential zur Gewebebahn verlaufen und auch entsprechende Empfänger (Fotozellen oder dergleichen) treffen. Die Sende- und Empfangseinrichtungen sind so ausgerichtet, daß sie durch die Florzone unterbrochen werden, jedoch durch die florlose Zone der Strahlengang nicht unterbrochen ist, wodurch es sehr genau möglich ist, die jeweilige Relativlage der durchlaufenden Bahn zu bestimmen und die Stoffbahn entsprechend ordnungsgemäß auszurichten.Such a device is known from DE 89 07 659 U1. Although this known device generally works satisfactorily, it has been found that in the case of long deflection rollers, inaccuracies may arise as a result of the deflection thereof, which is due to the fact that the distance between the frame carrying the photodetectors compared to the deflection roller does not remain constant over its length. The known device has one or more transmitters (light sources or the like), the rays of which run tangentially to the fabric web and also hit corresponding receivers (photocells or the like). The transmitters and receivers are aligned in such a way that they are interrupted by the pile zone, but the beam path is not interrupted by the non-pile zone, which makes it very possible to determine the relative position of the continuous web and to align the fabric accordingly.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die Vorrichtung zum seitlichen Abtasten der florlosen Zonen an Gewebebahnen hinsichtlich ihrer Erfassungsgenauigkeit zu verbessern.Proceeding from this prior art, the object of the invention is to improve the detection accuracy of the device for laterally scanning the floreless zones on fabric webs.

Zur Lösung dieser Aufgabe schlägt die Erfindung vor, daß der Rahmen mit Rollen unmittelbar auf der Oberfläche der Umlenkrolle geführt ist, wobei die Umlenkrolle zweckmäßig feststehend ist und eine polierte Oberfläche aufweist, und daß Sender und Empfänger des Fotodetektors auf einer im Abstand tangential zur Umlenkrolle auf dem Rahmen befestigten Platte angeordnet sind.To achieve this object, the invention proposes that the frame is guided with rollers directly on the surface of the deflection roller, the deflection roller is expediently fixed and has a polished surface, and that the transmitter and receiver of the photodetector are at a distance tangential to the deflection roller plate attached to the frame are arranged.

Durch diese Ausbildung wird erreicht, daß auch bei einer Durchbiegung der Umlenkrollen eine genaue Erfassung der florlosen Zone bzw. der Florzone erreicht wird, da sich der Abstand der Fotodetektoren an der Oberfläche der Umlenkrolle selbst unmittelbar orientiert. Hierdurch können Durchbiegungen oder sonstige Ungenauigkeiten der Umlenkrolle das einwandfreie Arbeiten der Fotodetektoren nicht ungünstig beeinflussen. Die Rollen des die Sender und Empfänger tragenden Rahmens laufen unmittelbar auf der Umlenkrolle ab und richten sich folglich immer nach deren momentaner Lage, so daß ein sehr genaues Ergebnis erzielbar ist.This configuration ensures that the floreless zone or the flor zone is precisely detected even when the deflection rollers bend, since the distance between the photodetectors is directly oriented on the surface of the deflection roller itself. As a result, deflections or other inaccuracies in the deflection roller cannot adversely affect the correct functioning of the photodetectors. The roles of the frame carrying the transmitters and receivers run directly on the deflection roller and consequently always depend on their current position, so that a very precise result can be achieved.

Eine bevorzugte Ausführungsform ist dadurch gekennzeichnet, daß der Rahmen an einem im Abstand tangential zur Umlenkrolle gerichteten Federblech derart aufgehängt ist, daß die Rollen unter Vorspannung an der Umlenkrolle anliegen.A preferred embodiment is characterized in that the frame is suspended from a spring plate directed at a distance tangential to the deflection roller in such a way that the rollers bear against the deflection roller under prestress.

Durch die Anordnung der federnden Anlage des Rahmens mit seinen Rollen an der Umlenkrolle wird eine Vereinfachung erzielt, die eine äußerst genaue Ausrichtung ermöglicht.By arranging the resilient contact of the frame with its rollers on the deflection roller, a simplification is achieved which enables extremely precise alignment.

Um das Einstellen der Vorrichtung alternativ zu erleichtern ist vorgesehen, daß die Platte mittels in Langlöchern geführten Schrauben mit dem Rahmen verschraubt ist, um ihren Abstand zur Umlenkrolle in Pfeilrichtung einstellen zu können.In order to facilitate the adjustment of the device alternatively, it is provided that the plate is screwed to the frame by means of screws guided in elongated holes in order to be able to adjust its distance to the deflection roller in the direction of the arrow.

Zum gleichen Zweck ist vorgesehen, daß die Platte mittels in Langlöchern geführten Schrauben auch quer zur Pfeilrichtung einstellbar ist.For the same purpose it is provided that the plate can also be adjusted transversely to the direction of the arrow by means of screws guided in elongated holes.

Bevorzugte Einzelheiten sind in den Ansprüchen 5 und 6 bezeichnet.
Um zu erreichen, daß die Florkante frei von Teilen des Flores mittels der Sende- und Empfangseinrichtung abtastbar ist, wird vorgeschlagen, daß in dem Rahmen Luftdüsen angeordnet sind, die von einer Druckluftquelle versorgt werden und so gegenüber der Florkante ausgerichtet sind, daß sie den Flor an der Florwurzel aufrichten.Preferred details are indicated in claims 5 and 6.
In order to ensure that the pile edge can be scanned free of parts of the pile by means of the transmitting and receiving device, it is proposed that air nozzles are arranged in the frame which are supplied by a compressed air source and are aligned with the pile edge so that they match the pile stand up at the pile root.

Um Störungen bei der Bearbeitung zu vermeiden, wird vorgeschlagen, daß auf dem Rahmen zwei Sender angeordnet sind, die drei Empfänger gegenüberstehen, wobei der Sender mit den Empfängern zum Abtasten der längslaufenden Florkante der florlosen Zone und der. Sender mit dem Empfänger zum Abtasten der Kanten der florlosen Zone quer zur Gewebebahn dient.In order to avoid malfunctions during processing, it is proposed that two transmitters are arranged on the frame, which face three receivers, the transmitter with the receivers for scanning the longitudinal pile edge of the floreless zone and the. Transmitter with the receiver serves to scan the edges of the floreless zone across the fabric web.

Durch entsprechende Schaltungsverknüpfung ist erreicht, daß beim Durchlauf einer quer zur Gewebebahn verlaufenden florlosen Zone die Abtasteinrichtung nicht nachteilig beeinflußt wird, indem nämlich dann, wenn die querverlaufende florlose Zone ertastet wird, die Sende- und Empfangseinrichtung abgeschaltet wird, die die Längsrandkante abtastet, um eine Fehlausrichtung in diesem Bereich zu vermeiden. Sobald die querverlaufende florlose Zone die entsprechende Sende- und Empfangsvorrichtung passiert hat und unter dieser Sende- und Empfangsvorrichtung wieder eine Florzone liegt, werden die Sende- und Empfangseinrichtungen wieder eingeschaltet, die den Längsrand der Gewebebahn abtasten.Through appropriate circuit linkage ensures that the scanning device is not adversely affected when passing through a floreless zone running transversely to the fabric web, namely by switching off the transmitting and receiving device which scans the longitudinal edge in order to misalign in this area when the transverse floreless zone is scanned to avoid. As soon as the transversal floreless zone has passed the corresponding sending and receiving device and a pile zone is again under this sending and receiving device, the sending and receiving devices that scan the longitudinal edge of the fabric web are switched on again.

Eine bevorzugte Weiterbildung wird noch darin gesehen, daß der Sender ein fächerförmiges Signal abgibt, das je nach Lage der Florkante der florlosen Zone längs der Gewebebahn den Empfänger, die Empfänger zusammen oder keinen der Empfänger trifft.A preferred further development is seen in the fact that the transmitter emits a fan-shaped signal which, depending on the position of the pile edge of the floreless zone along the fabric web, hits the receiver, the receiver together or none of the receivers.

Desweiteren ist bevorzugt vorgesehen, daß die drei möglichen Signale in einer Steuerung auswertbar sind, die ein Stellglied der Textilmaschine beaufschlagt.Furthermore, it is preferably provided that the three possible signals can be evaluated in a control which acts on an actuator of the textile machine.

Mittels des Stellgliedes der Textilmaschine kann eine entsprechende Querverschiebung der Textilbahn erfolgen, so daß die ordnungsgemäße Lage sich in Abhängigkeit von den ertasteten Signalen einstellen läßt.By means of the actuator of the textile machine, a corresponding transverse displacement of the textile web can take place, so that the correct position can be set depending on the sensed signals.

Weiterhin ist bevorzugt vorgesehen, daß, wenn der Sender und der Empfänger im Bereich der querverlaufenden florlosen Zone miteinander in Kontakt stehen, die Abtastung der Florkante in Längsrichtung abgeschaltet wird.Furthermore, it is preferably provided that when the transmitter and the receiver are in contact with one another in the region of the transverse floreless zone, the scanning of the pile edge in the longitudinal direction is switched off.

Schließlich ist bevorzugt, daß anstelle der Rollen beweglich gelagerte Kugeln verwendet werden.Finally, it is preferred that movably mounted balls are used instead of the rollers.

Figur 1 stellt einen Schnitt durch die Umlenkrolle dar mit der auf die Umlenkrolle aufgesetzten erfindungsgemäßen Vorrichtung. Man erkennt den Rahmen 1, der U-förmig die Umlenkrolle 3 umgreift. Die Umlenkrolle 3 ist zweckmäßig feststehend und mit einer polierten Oberfläche versehen. An dem Rahmen 1 sind mehrere Rollen 2 drehbar gelagert, die unmittelbar auf der Außenoberfläche der Umlenkrolle 3 laufen. Im gezeichneten Beispiel sind es insgesamt sechs Rollen 2, von denen sich je zwei Rollenpaare 2 an den Enden des Rahmens 1 und ein Rollenpaar 2 vorne und hinten etwa in der Mitte des Rahmens 1 befinden. Im Abstand und tangential zur Umlenkrolle 3 ist eine Platte 9 auf dem Rahmen 1 befestigt, die als Träger für die Fotodetektoren dient. Diese bestehen aus Sender und Empfängern, und zwar sind je ein Sender 7 und 8 auf der einen Seite der Platte 9 und drei Empfänger 4, 5, 6 auf der anderen Seite der Platte 9 angeordnet. Sie sind so eingerichtet, daß der zwischen ihnen ausgehende Lichtstrahl die Oberfläche der florlosen Zone der Gewebebahn 19 als Tangente berührt.FIG. 1 shows a section through the deflection roller with the one placed on the deflection roller device according to the invention. One recognizes the frame 1, which surrounds the deflection roller 3 in a U-shape. The deflection roller 3 is expediently fixed and provided with a polished surface. A plurality of rollers 2 are rotatably mounted on the frame 1 and run directly on the outer surface of the deflection roller 3. In the example shown, there are a total of six rollers 2, of which two pairs of rollers 2 are located at the ends of the frame 1 and one pair of rollers 2 at the front and rear approximately in the middle of the frame 1. At a distance and tangential to the deflection roller 3, a plate 9 is attached to the frame 1, which serves as a carrier for the photodetectors. These consist of transmitters and receivers, namely one transmitter 7 and 8 on one side of the plate 9 and three receivers 4, 5, 6 on the other side of the plate 9. They are set up so that the light beam emanating between them touches the surface of the floreless zone of the fabric web 19 as a tangent.

Um diese Tangente richtig einstellen zu können, ist die Platte 9 mit dem Rahmen 1 mittels in Langlöchern 10 geführten Schrauben 11 verbunden. Desweiteren ist die Platte 9 auch quer zur Pfeilrichtung 14 mittels in Langlöchern 12 geführten Schrauben 13 einstellbar.In order to be able to set this tangent correctly, the plate 9 is connected to the frame 1 by means of screws 11 guided in elongated holes 10. Furthermore, the plate 9 can also be adjusted transversely to the direction of the arrow 14 by means of screws 13 guided in elongated holes 12.

Figur 2 zeigt eine Draufsicht auf die Vorrichtung nach Figur 1. Auf der Umlenkrolle 3 ist der Rahmen 1 mit Rollen 2 verfahrbar. Man erkennt, daß der Rahmen 1 an seinen beiden Enden mit den Rollen 2 versehen ist, von denen zwei Rollen nicht sichtbar sind. An einem Ende des Rahmens 1 ist die Platte 9 in der vorbeschriebenen Weise befestigt (12,13). Auf der Platte 9 sind die beiden Sender 7,8 einerseits und drei Empfänger 4, 5, 6 andererseits angeordnet. Der Sender 8 arbeitet mit den Empfängern 5, 6 zum Abtasten der längslaufenden Florkante der Gewebebahn 19 zusammen, während der Sender 7 mit dem Empfänger 4 zum Abtasten der Kanten einer florlosen Zone quer zur Gewebebahn-Längserstreckung zusammenarbeitet. Der Sender 8 kann dabei ein fächerförmiges Signal abgeben, das je nach Lage der Florkante längs der Gewebebahn 19 den Empfänger 5 allein, die Empfänger 5,6 zusammen oder keinen der beiden Empfänger 5,6 trifft. Jedes der drei möglichen Signale wird in einer Steuerung ausgewertet, die in der Textilmaschine vorgesehen ist und ein Stellglied der Maschine beaufschlagt. Wenn der Sender 7 und der Empfänger 4 im Bereich der querlaufenden florlosen Zone miteinander in Kontakt stehen, wird die Abtastung der längslaufenden Florkante abgeschaltet.Figure 2 shows a plan view of the device according to FIG. 1. The frame 1 can be moved with rollers 2 on the deflection roller 3. It can be seen that the frame 1 is provided at both ends with the rollers 2, of which two rollers are not visible. The plate 9 is fastened to one end of the frame 1 in the manner described above (12, 13). The two transmitters 7, 8 on the one hand and three receivers 4, 5, 6 on the other hand are arranged on the plate 9. The transmitter 8 cooperates with the receivers 5, 6 for scanning the longitudinal flank edge of the fabric web 19, while the transmitter 7 cooperates with the receiver 4 for scanning the edges of a floreless zone transverse to the length of the fabric web. The transmitter 8 can emit a fan-shaped signal which, depending on the position of the pile edge along the fabric web 19, hits the receiver 5 alone, the receiver 5,6 together or neither of the two receivers 5,6. Each of the three possible signals is evaluated in a controller which is provided in the textile machine and acts on an actuator of the machine. When the transmitter 7 and the receiver 4 are in contact in the region of the transverse floreless zone, the scanning of the longitudinal pile edge is switched off.

Figur 3 zeigt eine andere Lösung der gestellten Aufgabe. Der Rahmen 1 ist dabei an einem im Abstand tangential zur Umlenkrolle 3 gerichteten Federblech 16 derart aufgehängt, daß die Rollen 2 unter Vorspannung an der Umlenkrolle 3 anliegen. Die Verbindung zwischen dem Federblech 16 und dem Rahmen 1 erfolgt durch ein Lagerstück 15, in welchem der Rahmen 1 in Pfeilrichtung 20 um eine Welle 18 drehbar gelagert ist. Dies stellt eine Vereinfachung dar, weil der Rahmen 1 sich immer selbsttätig über die ganze Länge der Umlenkrolle 3 an deren Oberfläche anlegen kann. Die vier Rollen 2 sind paarweise mit senkrecht zueinander stehenden Laufflächen angeordnet. Das Federblech 16 ist mit einem Maschinenteil 17 verbunden.Figure 3 shows another solution to the problem. The frame 1 is directed at a tangential to the deflection roller 3 at a distance Spring plate 16 suspended in such a way that the rollers 2 bear against the deflection roller 3 under pretension. The connection between the spring plate 16 and the frame 1 is made by a bearing piece 15, in which the frame 1 is rotatably mounted about a shaft 18 in the direction of the arrow 20. This represents a simplification, because the frame 1 can always create itself over the entire length of the deflection roller 3 on its surface. The four rollers 2 are arranged in pairs with perpendicular running surfaces. The spring plate 16 is connected to a machine part 17.

Figur 4 stellt eine Draufsicht auf die Ausführung nach Figur 3 dar. Sie gibt Auskunft über die Anordnung der Rollen 2 und die Lage des Federblechs 16. An dem Rahmen 1 befindet sich die Platte 9 die, wie oben beschrieben, als Träger für die Fotodetektoren dient. In dem Rahmen 1 können Luftdüsen untergebracht sein, die von einer Druckluftquelle versorgt, Blasluft gegen die Florkante blasen, so daß etwa umgelegter Flor gegenüber der Florwurzel aufgerichtet wird. Die Blasdüsen können in dem Rahmen 1 selbst oder auch in einem gesonderten Luftklotz angebracht sein.FIG. 4 shows a top view of the embodiment according to FIG. 3. It provides information about the arrangement of the rollers 2 and the position of the spring plate 16. On the frame 1 there is the plate 9, which, as described above, serves as a support for the photodetectors . In the frame 1, air nozzles can be accommodated, which are supplied by a compressed air source, blow blown air against the pile edge, so that any folded pile is erected against the pile root. The blowing nozzles can be mounted in the frame 1 itself or in a separate air block.

Die Vorrichtung zum Abtasten der florlosen seitlichen Längsrandkanten von Gewebebahnen ist hinsichtlich ihrer Funktion nachstehend näher beschrieben. Eine Gewebebahn läuft in Längsrichtung durch die Vorrichtung, wobei die beiden Längsrandkanten der Gewebebahn florlose Zonen aufweisen. Zusätzlich kann die Gewebebahn querverlaufende florlose Zonen aufweisen (zum Beispiel bei Frotteehandtücher oder dergleichen). Die Vorrichtung dient zur Steuerung der Lageausrichtung der Gewebebahn auf den Bearbeitungsmaschinen. Es ist eine ordnungsgemäße Steuerung des Bewegungspfades der Gewebebahn erforderlich ist, damit diese ordnungsgemäß mit Längssäumen versehen werden kann oder auch andere Bearbeitungsvorgänge maschineller Art ausgeübt werden können. Zur Abtastung der längslaufenden Randkanten sind an beiden Seiten der Gewebebahn die Abtastvorrichtungen vorgesehen, die aus dem Sender und den Empfängern bestehen. Es gibt dabei folgende mögliche Lagen:The device for scanning the floreless lateral longitudinal edge edges of fabric webs is described in more detail below with regard to its function. A fabric web runs through the device in the longitudinal direction, the two longitudinal edge edges of the fabric web having floreless zones. In addition, the fabric web can have transverse floreless zones (for example in the case of terry towels or the like). The device serves to control the positional alignment of the fabric web on the processing machines. Proper control of the path of movement of the fabric web is required so that it can be properly hemmed or other machining operations can be carried out mechanically. The scanning devices, which consist of the transmitter and the receivers, are provided on both sides of the fabric web for scanning the longitudinal edge edges. The possible locations are as follows:

Eine erste Lage (Sollage) ist dann erreicht, wenn das System, bestehend aus dem Sender 8 und den Empfängern 5 + 6 so ausgerichtet ist, daß der vom Sender 8 ausgehende Strahl zum Empfänger 6 anzeigt, daß hier keine Tuchbahn vorhanden ist, wohingegen der vom Sender 8 ausgehende, zum Empfänger 5 gerichtete Strahl anzeigt, daß hier zwischen die florlose Zone angeordnet ist. Diese Position ist die normale und erwünschte Arbeitsposition. Sofern sich die Stoffbahn so verschiebt, daß beide vom Sender 8 ausgehenden Strahlen über die florlose Zone zu den Empfängern 5 und 6 hin gelangen, so wird hieraus ein Signal für die Querverschiebung der Stoffbahn abgeleitet, so daß diese automatisch maschinell soweit querverschoben wird, daß wieder einer der beiden Strahlen, nämlich der Strahl zwischen Sender 8 und Empfänger 5 über die florlose Zone verläuft und der andere Strahl zwischen Sender 8 und Empfänger 6 neben der florlosen Zone verläuft.A first position (target position) is reached when the system consisting of the transmitter 8 and the receivers 5 + 6 is oriented so that the beam coming from the transmitter 8 to the receiver 6 indicates that there is no cloth web, whereas the beam emanating from the transmitter 8 and directed towards the receiver 5 indicates that here is arranged between the floreless zone. This position is the normal and desired working position. If the fabric moves so that both emanating from the transmitter 8 If beams reach the receivers 5 and 6 via the floreless zone, a signal for the transverse displacement of the fabric web is derived therefrom, so that it is automatically mechanically displaced so far that one of the two beams, namely the beam between transmitter 8 and receiver 5 runs over the floreless zone and the other beam runs between transmitter 8 and receiver 6 next to the floreless zone.

Es ist auch Position möglich, bei der beide vom Sender 8 ausgehenden Strahlen neben der florlosen Zone außerhalb der Tuchbahn angeordnet sind. Bei dieser Position wird die Stoffbahn so gesteuert, daß sie verschoben wird, bis wieder die Sollposition erreicht ist.A position is also possible in which both beams emanating from the transmitter 8 are arranged next to the floreless zone outside the cloth web. At this position, the fabric is controlled so that it is moved until the target position is reached again.

Eine alternative Möglichkeit besteht dergestalt, daß die Abtastung der Randkante in der Weise erfolgt, daß der vom Sender 8 ausgehende Strahl zum Empfänger 5 hin durch die Florzone verläuft, während der andere Strahl vom Sender 8 zum Empfänger 6 durch die florlose Zone verläuft. Dies kann wiederum eine Sollposition sein. Bei einer Abweichung von dieser Position verlaufen beide vom Sender ausgehenden Strahlen entweder im Bereich der florlosen Zone oder durch die Florzone der Gewebebahn. Durch die Empfangseinrichtung wird eine Steuerung der Maschine in Betrieb gesetzt, mittels derer die Gewebebahn in entsprechender Richtung querverschoben wird, um wieder die Sollposition zu erreichen. Bei dieser letztbeschriebenen Anordnung ist es erforderlich, daß eine zusätzliche Einrichtung vorgesehen ist, die verhindert, daß dann, wenn eine querverlaufende florlose Zone durchläuft, ein Fehlsignal auf die Steuerung ausgelöst wird. Hierzu ist das weitere Sende- und Empfangssystem (Sender 7 und Empfänger 4) vorgesehen. Im Normalfall, also einer mit Flor besetzten Zone gelangt der vom Sender 7 ausgehende Strahl nicht zum Empfänger 4, so daß kein Signal erfolgt. Sofern eine querverlaufende florlose Zone den Strahlengang zwischen Sender 7 und Empfänger 4 erreicht, kommt das vom Sender 7 ausgehende Signal zum Empfänger 4, der dann die Sende- und Empfangseinrichtung 8 bzw. 5, 6 ausschaltet, bis die querverlaufende Zone durchgelaufen ist, woraufhin dann wiederum die Sende-Empfangseinrichtung 8, 5, 6 eingeschaltet wird. Sofern diese zusätzliche Einrichtung nicht vorgesehen wäre, würde beim Durchlauf durch die querverlaufende florlose Zone ein Fehlsignal ergehen, da dann auch bei in Sollposition befindlicher Stoffbahn beide Strahlen, die von der Sendeeinrichtung 8 ausgehen, ungehindert zu der Empfangseinrichtung 5 und 6 hingelangen könnten, so daß eine Verstellung der Stoffbahn quer zur Durchlaufrichtung erfolgen würde. Dies ist unerwünscht und würde zu Fehlern führen.An alternative possibility is such that the edge edge is scanned in such a way that the beam coming from the transmitter 8 runs to the receiver 5 through the pile zone, while the other beam runs from the transmitter 8 to the receiver 6 through the flowerless zone. This can in turn be a target position. In the event of a deviation from this position, both beams emanating from the transmitter either run in the area of the floreless zone or through the pile zone of the fabric web. A control of the machine is started by the receiving device, by means of which the fabric web is operated is shifted in the corresponding direction to reach the target position again. With this last-described arrangement, it is necessary to provide an additional device which prevents a false signal from being triggered on the control when a floreless zone runs through. For this purpose, the further transmission and reception system (transmitter 7 and receiver 4) is provided. In the normal case, that is to say a zone occupied by pile, the beam coming from the transmitter 7 does not reach the receiver 4, so that no signal is produced. If a transverse floreless zone reaches the beam path between the transmitter 7 and the receiver 4, the signal emanating from the transmitter 7 comes to the receiver 4, which then switches off the transmitting and receiving device 8 or 5, 6 until the transverse zone has passed, whereupon then turn the transceiver 8, 5, 6 is turned on. If this additional device were not provided, a false signal would be given when passing through the transversal floreless zone, since then even with the fabric web in the desired position, both beams emanating from the transmitting device 8 could reach the receiving device 5 and 6 unhindered, so that the web of fabric would be adjusted transversely to the direction of flow. This is undesirable and would lead to errors.
