Description

Die Erfindung betrifft eine Spannmaschine entsprechend dem Oberbegriff des Anspruches 1.The invention relates to a stenter according to the preamble of claim 1.

Werden textile Warenbahnen einer Spannmaschine zum Zwecke einer Behandlung zugeführt, so muss die den Spannketten der Spannmaschine aufgegebene Warenbahn frei von jeglichen Verzügen sein. Zu diesem Zweck ist es bekannt, im Bereich vor dem Warenbahn-Einlaufteil der Spannmaschine eine Ausrichtvorrichtung anzuordnen (wie sie beispielsweise durch die DE-A-1 906 801 bekannt ist), in der verschiedene Richtwalzen für die Beseitigung von Längs-, Bogen- und Diagonalverzügen der Warenbahn vorgesehen sind. Vorrichtungen dieser Art sind sehr aufwendig und benötigen im Bereich vor dem Einlaufteil der Spannmaschine einen verhältnismässig grossen zusätzlichen Raum.If textile material webs are fed to a tensioning machine for the purpose of treatment, the material web fed into the tensioning chains of the tensioning machine must be free of any distortions. For this purpose it is known to arrange an alignment device in the area in front of the web inlet part of the tensioning machine (as is known, for example, from DE-A-1 906 801), in which various straightening rollers for the removal of longitudinal, curved and Diagonal warping of the web is provided. Devices of this type are very complex and require a relatively large additional space in the area in front of the inlet part of the tensioning machine.

Durch die DE-AS-2 417 409 ist ferner eine Ausführung bekannt, bei der im Einlaufteil einer Spannmaschine eine Einzugswalze vorgesehen ist, die in axialer Richtung in drei mit veränderbarer Drehzahl antreibbare Walzenteile unterteilt ist. Vor dieser Einzugswalze sind ferner noch einige Umlenkwalzen sowie zwei Breitstreckenwalzen angeordnet. Durch diese Ausbildung ist es möglich, Schräg- und Bogenverzüge einer textilen Warenbahn auszurichten. Beim Ausrichten von grösseren Bogen- und Diagonalverzügen können jedoch Schwierigkeiten durch relativ grosse Differenzgeschwindigkeiten auftreten (in der auszurichtenden Warenbahn erscheinen dann sogenannte Krähenfüsse). Insbesondere zum Ausrichten grösserer Bogen- und Diagonalverzüge müssen daher vor dem Einlaufteil der bekannten Spannmaschine weitere Richtgeräte angeordnet werden.From DE-AS-2 417 409 an embodiment is also known in which a feed roller is provided in the inlet part of a tensioning machine, which is divided in the axial direction into three roller parts which can be driven with variable speed. In front of this feed roller there are also some deflection rollers and two wide section rollers. This training makes it possible to align diagonal and arch distortions of a textile web. When aligning larger curved and diagonal distortions, difficulties can arise due to relatively large differential speeds (so-called crow's feet then appear in the web to be aligned). In particular for aligning larger sheet and diagonal distortions, further straightening devices must therefore be arranged in front of the inlet part of the known tensioning machine.

Der Erfindung liegt die Aufgabe zugrunde, eine Spannmaschine der im Oberbegriff des Anspruches 1 vorausgesetzten Art so auszubilden, dass sie bei relativ einfacher und raumsparender Bauweise das Einführen von vollkommen ausgerichteten Warenbahnen in die Spannketten gestattet.The invention is based on the object of designing a tensioning machine of the type required in the preamble of claim 1 in such a way that, with a relatively simple and space-saving design, it allows the introduction of completely aligned webs of material into the tensioning chains.

Diese Aufgabe wird erfindungsgemäss durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.According to the invention, this object is achieved by the characterizing features of claim 1.

Im Gegensatz zu der Ausführung gemäss DE-A-2 417 409 ist bei der erfindungsgemässen Spannmaschine die Einzugswalze ungeteilt, also verhältnismässig einfach ausgebildet. Während ferner bei den bekannten Ausführungen eine verhältnismässig grosse Anzahl von Umlenkwalzen im Einlaufteil der Spannmaschine vorgesehen ist, befindet sich im Einlaufteil der erfindungsgemässen Spannmaschine statt dessen eine komplette Warenbahn-Ausrichtvorrichtung mit der Bogenrichtwalze, den beiden einander entgegengesetzt verschwenkbaren Diagonal- Richtwalzen und der Schussfaden-Messeinrichtung. Dies fürt zu einer baulich einfachen und raumsparenden Ausbildung der Spannmaschine, insbesondere ihres Einlaufteiles.In contrast to the version according to DE-A-2 417 409, in the tensioning machine according to the invention the feed roller is undivided, that is to say it is relatively simple. Furthermore, while in the known designs a relatively large number of deflecting rollers is provided in the inlet part of the tensioning machine, there is instead in the inlet part of the tensioning machine according to the invention a complete web alignment device with the sheet straightening roller, the two diagonally straightening rollers which can be pivoted in opposite directions, and the weft thread measuring device . This leads to a structurally simple and space-saving design of the tensioning machine, especially its inlet part.

Im Unterschied zu dem aus der DE-A-1 906 801 bekannten Stand der Technik ist bei der erfindungsgemässen Ausführung die Warenbahn-Ausrichtvorrichtung nicht als gesonderte Baueinheit vor der Spannmaschine angeordnet, sondern sie ist im Warenbahneinlaufteil integriert. Dadurch ergibt sich eine wesentliche Verringerung des Raumbedarfes und des konstruktiven Aufwandes.In contrast to the prior art known from DE-A-1 906 801, in the embodiment according to the invention the web alignment device is not arranged as a separate unit in front of the tensioning machine, but is integrated in the web inlet part. This results in a significant reduction in the space requirement and the design effort.

Soll die erfindungsgemässe Spannmaschine im wesentlichen nur für die Behandlung von gewebten Warenbahnen verwendet werden, so genügt eine Warenbahn-Ausrichtvorrichtung mit einer konkav-konvex verstellbaren Bogenrichtwalze, zwei entgegengesetztzueinandnerverschwenkbaren Diagonal- Richtwalzen und einer Schussfaden-Messeinrichtung. Soll die Spannmaschine jedoch auch oder vor allem für gewirkte Warenbahnen eingesetzt werden, so enthält die Warenbahn-Ausrichtvorrichtung zweckmässig zusätzlich - in Warenbahn-Transportrichtung betrachtet - eine erste Breitstreckwalze vor der Bogenrichtwalze und eine zweite Breitstreckwalze zwischen den beiden Diagonal-Richtwalzen und der Schussfaden-Messeinrichtung. Dadurch werden die Warenbahnkanten einmal vor der Bogenrichtwalze und zum andern nach den Diagonal-Richtwalzen, jedoch vor der Schussfaden-Messeinrichtung ausgerollt bzw. glattgestrichen, so dass eine einwandfreie Richtarbeit über die ganze Breite der Warenbahn erfolgt und die einwandfrei ausgebreitete bzw. ausgerollte Warenbahn der Schussfaden-Messeinrichtung zum Zwecke einer einwandfreien Messung der Schussfadenlage zugeführt wird.If the tensioning machine according to the invention is to be used essentially only for the treatment of woven material webs, a material web alignment device with a concave-convex adjustable sheet straightening roller, two diagonally straightening rollers which can be pivoted in opposite directions and a weft thread measuring device is sufficient. However, if the tensioning machine is also to be used, or especially for knitted webs, then the web alignment device also expediently contains - viewed in the web transport direction - a first spreader roller in front of the sheet straightening roller and a second spreader roller between the two diagonal straightening rollers and the weft thread measuring device . As a result, the web edges are rolled out or smoothed out in front of the sheet straightening roller and on the other hand after the diagonal straightening rollers, but in front of the weft measuring device, so that perfect straightening work takes place across the entire width of the web and the flawlessly spread or rolled out web of weft threads -Measuring device is fed for the purpose of a perfect measurement of the weft thread position.

Zweckmässige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche und werden im Zusammenhang mit der folgenden Beschreibung zweier in der Zeichnung veranschaulichter Ausführungsbeispiele erläutert. Es zeigen:

  • Fig. 1 eine ganz schematisch gehaltene Seitenansicht einer Spannmaschine;
  • Fig. 2 eine schematische Seiten-Schnittansicht des Warenbahn-Einlaufteiles der Spannmaschine in einer Ausführung für in vertikalen Ebenen umlaufende Spannketten;
  • Fig. 3 eine schematische Seiten-Schnittansicht des Einlaufteiles der Spannmaschine mit in horizontalen Ebenen umlaufenden Spannketten.
Useful embodiments of the invention are the subject of the dependent claims and are explained in connection with the following description of two exemplary embodiments illustrated in the drawing. Show it:
  • Figure 1 is a very schematic side view of a tensioner.
  • Figure 2 is a schematic side sectional view of the web inlet part of the tensioning machine in an embodiment for tension chains rotating in vertical planes.
  • Fig. 3 is a schematic side sectional view of the inlet part of the tensioning machine with tension chains rotating in horizontal planes.

In Fig. 1 ist eine Spannmaschine 1, die für irgendeine der bekannten Behandlungsarten von textilen Warenbahnen 2 bestimmt ist, nur ganz schematisch angedeutet. Die Spannmaschine 1 enthält einen Warenbahneinlaufteil 3, einen Hauptbehandlungsteil 4 sowie einen Warenbahnauslaufteil 5. Während es im vorliegenden Falle um die besondere Ausbildung des Warenbahneinlaufteiles 3 geht, können der Hauptbehandlungsteil 4 sowie der Warenbahnauslaufteil 5 in üblicher Weise ausgebildet sein. Die Warenbahn 2 durchläuft die Spannmaschine 1 in Richtung der Pfeile 6. Eine zu behandelnde textile Warenbahn 2 wird im Warenbahneinlaufteil 3 der Spannmaschine 1 in üblicher, hier nicht näher veranschaulichter Weise zwei endlos umlaufenden Spannketten 7 zugeführt, die - wie allgemein bekannt - senkrecht zur Zeichenebene der Fig. 1 hintereinanderliegen und die Warenbahnlängskanten ergreifen. Die Spannketten können dabei in bekannter Weise als Nadelketten oder als Kluppenketten ausgeführt sein. Im Beispiel der Fig. 1 laufen die Spannketten 7 in vertikalen Ebenen um, d.h. die zugehörigen Kettenumlenkräder 7a drehen sich um horizontale Achsen.In Fig. 1, a tensioning machine 1, which is intended for any of the known types of treatment of textile webs 2, is only indicated very schematically. The tensioning machine 1 contains a web inlet part 3, a main treatment part 4 and a web outlet part 5. While in the present case the special design of the web inlet part 3 is concerned, the main treatment part 4 and the web outlet part 5 can be designed in the usual way. The material web 2 runs through the tensioning machine 1 in the direction of the arrows 6. A textile material web 2 to be treated is fed in the web entry part 3 of the tensioning machine 1 in a conventional manner (not shown here in more detail) to two endless rotating tension chains 7 which, as is generally known, perpendicular to the plane of the drawing 1 lie in a row and take the longitudinal edges of the web. The tension chains can be designed in a known manner as needle chains or as chain clips. In the example of Fig. 1, the tension chains 7 run in vertical planes, i.e. the associated chain deflection wheels 7a rotate about horizontal axes.

Anhand der Fig. 2 sei nun zunächst eine Ausführungsform des im vorliegenden Falle vor allem interessierenden Warenbahneinlaufteiles 3 beschrieben, und zwar ebenfalls für eine Spannmaschine 1 mit in vertikalen Ebenen umlaufenden Spannketten (wie anhand der Fig. 1 erläutert).An embodiment of the web inlet part 3, which is of particular interest in the present case, will now be described with reference to FIG. 2, also for a tensioning machine 1 with tension chains rotating in vertical planes (as explained with reference to FIG. 1).

Die Spannmaschine 1 enthält in ihrem Einlaufteil 3 eine - in Warenbahntransportrichtung (Pfeil 6) gesehen - vor den Spannketten liegende Einzugswalze 8, die über ihre Länge ungeteilt und mit einem im wesentlichen zylindrischen, starren Mantel ausgebildet ist.The tensioning machine 1 contains in its inlet part 3 a feed roller 8 lying in front of the tensioning chains, as seen in the web transport direction (arrow 6), which is undivided along its length and has an essentially cylindrical, rigid jacket.

In Warenbahntransportrichtung (Pfeil 6) vor der Einzugswalze 8 ist im Warenbahneinlaufteil 3 eine komplette Warenbahn-Ausrichtvorrichtung 9 angeordnet. Diese Warenbahn-Ausrichtvorrichtung 9 enthält - in Richtung des Warenbahntransportes (Pfeil 6) betrachtet - eine konkav-konvex verstellbare Bogenrichtwalze 10, zwei einander entgegengesetzt verschwenkbare Diagonalrichtwalzen 11, 12 sowie eine Schussfaden-Messeinrichtung 13.In the web transport direction (arrow 6) in front of the feed roller 8, a complete web alignment device 9 is arranged in the web inlet part 3. This web aligning device 9 contains - viewed in the direction of web transport (arrow 6) - a concave-convex adjustable sheet straightening roller 10, two diagonally straightening rollers 11, 12 which can be pivoted in opposite directions and a weft thread measuring device 13.

Da im vorliegenden Falle davon ausgegangen wird, dass diese Spannmaschine 1 mit ihrem Warenbahn- einlaufteil 3 für das Ausrichten und Behandeln von gewirkten Warenbahnen bestimmt ist, enthält die Warenbahn-Ausrichtvorrichtung 9 - wiederum in Warenbahntransportrichtung (Pfeil 6) betrachtet - vor der Bogenrichtwalze 10 noch eine erste Breitstreckwalze 14 und zwischen den beiden Diagonal- richtwalzen 11, 12 und der Schussfaden-Messeinrichtung 13 eine zweite Breitstreckwalze 15. Diese beiden Breitstreckwalzen 14, 15 können in herkömmlicher Weise insbesondere zum Ausrollen der Warenbahnkantenbereiche ausgeführt sein, wobei sie entgegengesetzt zur Warenbahntransportrichtung (Pfeil 6) antreibbarsind (vgl. Pfeile 14a bis 15a).Since it is assumed in the present case that this tensioning machine 1 with its web inlet part 3 is intended for aligning and treating knitted webs, the web alignment device 9 - again viewed in the web transport direction (arrow 6) - still contains the sheet straightening roller 10 a first spreader roller 14 and between the two diagonal straightening rollers 11, 12 and the weft thread measuring device 13 a second spreader roller 15. These two spreader rollers 14, 15 can be designed in a conventional manner in particular to roll out the web edge areas, whereby they are opposite to the web transport direction (arrow 6) can be driven (see arrows 14a to 15a).

Die Schussfaden-Messeinrichtung 13 kann im wesentlichen durch eine Anzahl üblicher oberer und unterer Messköpfe 16 und 17 gebildet sein, zwischen denen die Warenbahn 2 hindurchgeführt wird. Damit eine genaue Messung der Schussfadenlage bei der zwischen den Messköpfen 16 und 17 hindurchtransportierten Warenbahn 2 erfolgen kann, sind unmittelbar vor bzw. hinter der Schussfaden-Messeinrichtung 13 je eine Beruhigungswalze 18, 19 zur Stabilisierung der ausgebreiteten Warenbahn vorgesehen. Beide Beruhigungswalzen 18, 19 besitzen einen zylindrischen, glatten und vorzugsweise aus Stahl bestehenden Mantel. Die unmittelbar vor der Schussfaden-Messeinrichtung 13 angeordnete erste Beruhigungswalze 18 ist dabei mit ganz geringem Abstand hinter der zweiten Breitstreckwalze 15 angeordnet, wie es aus Fig. 2 deutlich zu ersehen ist, während die Warenbahn 2 von der hinter der Schussfaden-Messeinrichtung 13 liegenden zweiten Beruhigungswalze 19 direkt auf die Einzugswalze 8 aufläuft.The weft measuring device 13 can essentially be formed by a number of conventional upper and lower measuring heads 16 and 17, between which the web 2 is passed. So that a precise measurement of the weft thread position can be carried out on the web 2 transported between the measuring heads 16 and 17, a calming roller 18, 19 is provided in front of or behind the weft measuring device 13 to stabilize the spread web. Both calming rollers 18, 19 have a cylindrical, smooth and preferably made of steel jacket. The first calming roller 18 arranged directly in front of the weft measuring device 13 is arranged at a very short distance behind the second spreader roller 15, as can be clearly seen from FIG. 2, while the web 2 is separated from the second one behind the weft measuring device 13 Calming roller 19 runs directly onto the feed roller 8.

Als Richtwalzen 10, 11, 12 können ohne weiteres in an sich bekannter Weise ausgeführte und anzuordnende Richtwalzen verwendet werden. Die konkav-konvex verstellbare Bogenrichtwalze 10 kann also mit abschnittsweise (vorzugsweise in ihren mittleren Abschnitten) im Durchmesser veränderbar sein, wie es durch strichpunktierte Kreise in Fig. 2 angedeutet ist, wobei sie jedoch bei unverzogenen Warenbahnabschnitten eine im wesentlichen zylindrische oder leicht ballige Grundform aufweist. Die beiden Diagonalrichtwalzen 11, 12 können - abgesehen von ihrer zueinander parallelen Grundstellung - einander entgegengesetzt verschwenkt werden, wie es in Fig. 2 durch voll ausgezogene und strichpunktierte Linien sowie durch Doppelpfeile 11a bzw. 12a angedeutet ist.The straightening rolls 10, 11, 12 can be used in a manner known per se and can be used to straightening rolls. The concave-convex adjustable straightening roller 10 can thus be changed in sections (preferably in its central sections) in diameter, as indicated by dash-dotted circles in FIG. 2, but it has an essentially cylindrical or slightly spherical basic shape in the case of undistorted web sections . The two diagonal straightening rollers 11, 12 can - apart from their mutually parallel basic position - be pivoted in opposite directions, as is indicated in Fig. 2 by fully solid and dash-dotted lines and by double arrows 11a and 12a.

Alle genannten Walzen des Warenbahneinlaufteiles 3 können durch nicht näher veranschaulichte Antriebseinrichtungen von aussen her in geeigneter Weise angetrieben sein. Die Einzugswalze 8 kann - da sie in vertikalen Ebenen umlaufenden Spannketten 7 zugeordnet ist - ortsfest gelagert sein.All of the rollers of the web inlet part 3 mentioned can be driven in a suitable manner from the outside by drive devices (not illustrated in more detail). The feed roller 8 can - since it is assigned in vertical planes revolving tension chains 7 - be fixed.

Der Spannmaschine 1 ist ferner eine herkömmliche, in der Zeichnung nicht näher veranschaulichte Steuereinrichtung zugeordnet, die einerseits mit den drei Richtwalzen 10, 11, 12 und andererseits mit der Schussfaden-Messeinrichtung 13 steuerungsmässig verbunden ist. Auf diese Weise werden von der Schussfaden-Messeinrichtung 13 die SchussfadenLagen der Warenbahn 2 bzw. der jeweils die Einrichtung 13 durchlaufenden Warenbahnabschnitte überprüft und sofort nach Feststellung irgendwelcher Warenbahnverzüge entsprechende Signale an die Steuereinrichtung weitergeleitet, durch die dann entsprechende Steuersignale an die für die erforderliche Richtarbeit zuständigen Richtwalzen (10, 11 bzw. 12) weitergeleitet werden, so dass ein unverzügliches Korrigieren der Schussfadenlage erfolgen kann.The tensioning machine 1 is also assigned a conventional control device, not shown in the drawing, which is connected on the one hand with the three straightening rollers 10, 11, 12 and on the other hand with the weft thread measuring device 13 in terms of control. In this way, the weft thread measuring device 13 checks the weft thread positions of the web 2 or the web sections passing through the device 13 and immediately after detection of any web delays, corresponding signals are forwarded to the control device, through which corresponding control signals are then sent to the person responsible for the required straightening work Straightening rollers (10, 11 or 12) are forwarded so that the weft thread position can be corrected immediately.

Fig. 3 zeigt ein gegenüber dem vorherigen Ausführungsbeispiel etwas abgewandeltes Beispiel. Der Einfachheit halber sind in dieser Fig. 3 Einrichtungsteile, die mit gleichartigen Einrichtungsteilen der Fig. 2 übereinstimmen, mit dem gleichen Bezugszeichen unter Hinzufügung eines Striches bezeichnet, so dass eine nochmalige Erläuterung dieser gleichartigen Einrichtungsteile weitgehend unterbleiben kann.Fig. 3 shows an example slightly modified compared to the previous embodiment. For the sake of simplicity, in FIG. 3, device parts that correspond to similar device parts from FIG. 2 are designated by the same reference number with the addition of a dash, so that a repeated explanation of these similar device parts can largely be omitted.

Bei der Spannmaschine 1' bzw. dem Warenbahn- einlaufteil 3' gemäss Fig. 3 handelt es sich vor allem um eine Ausführungsform, bei der die Spannketten in an sich bekannter Weise in horizontalen Ebenen umlaufen. Bei in horizontalen Ebenen umlaufenden Spannketten ist es erforderlich, das Einlaufniveau der Einzugswalze 8' gegenüber den Spannketten dann zu verändern, wenn in dieser Spannmaschine 1' die Warenbahnen 2' wahlweise von Nadeln der Spannkette oder den Kluppen der Spannketten erfasst und transportiert werden können. In Fig. 2 können die Warenbahnen 2' daher entweder in dem höher angedeuteten Niveau 20 für Nadeln oder in dem etwas tieferliegenden Niveau 21 für Kluppen geführt werden.The tensioning machine 1 'or the web entry part 3' according to FIG. 3 is above all an embodiment in which the tensioning chains rotate in horizontal planes in a manner known per se. In the case of tension chains rotating in horizontal planes, it is necessary to change the entry level of the feed roller 8 'compared to the tension chains when in this tensioning machine 1' the webs 2 'can be picked up and transported either by needles of the tension chain or the clips of the tension chains. In FIG. 2, the webs 2 'can therefore be guided either in the higher level 20 for needles or in the lower level 21 for clips.

Zu dem zuvor genannten Zweck ist die Einzugswalze 8' in ihrer Höhenlage einstellbar gelagert, wie es in Fig. 3 durch einen Doppelpfeil 22 sowie durch ausgezogene und strichpunktierte Linien für die Einzugswalze 8' angedeutet ist. Die Einzugswalze 8' kann dabei mit ihren Endachsen an den freien Enden zweier Arme 24 gelagert sein, die um eine gemeinsame horizontale Achse 25 geschwenkt werden können (ggf. in einstellbarer Weise).For the aforementioned purpose, the feed roller 8 'is adjustably mounted in its vertical position, as is indicated in FIG. 3 by a double arrow 22 and by solid and dash-dotted lines for the feed roller 8'. The feed roller 8 'can be supported with its end axes at the free ends of two arms 24 which can be pivoted about a common horizontal axis 25 (if necessary in an adjustable manner).

Es sei an dieser Stelle nochmals erwähnt, dass die zuvor beschriebenen Spannmaschinen-Ausführungen, und zwar sowohl gemäss den Fig. 1 und 2 als auch gemäss Fig. 3, insbesondere für ein Ausrichten von gewirkten Warenbahnen, also von Warenbahnen, deren Kanten bzw. Kantenbereiche besonders stark zu einem Einrollen neigen, ausgebildet sind. Falls mit einer gleichartigen Spannmaschine sowohl gemäss Fig. 1 und 2 als auch gemäss Fig. 3 nur gewebte Warenbahnen ausgerichtet und behandelt werden sollen, bei denen kein Einrollen der Warenbahnkanten zu befürchten ist, dann können die beiden Breitstreckwalzen 14, 15 bzw. 14', 15' entfallen, so dass dann eine der Spannmaschine 1 bzw. 1' zugeführte Warenbahn 2 bzw. 2' zunächst direkt auf die Bogenrichtwalze 10 bzw. 10' gelangt; von der in Warenbahn-Transportrichtung letzten Diagonalrichtwalze 11 bzw. 11' läuft die Warenbahn 2 bzw. 2' dann direkt auf die erste Beruhigungswalze 18 bzw. 18'.At this point it should be mentioned again that the previously described clamping machine designs, both according to FIGS. 1 and 2 as 3, in particular for aligning knitted material webs, that is, material webs whose edges or edge regions tend to curl particularly strongly. If only woven webs are to be aligned and treated with a similar tensioning machine according to FIGS. 1 and 2 and according to FIG. 15 'are dispensed with, so that a web of material 2 or 2' fed to the tensioning machine 1 or 1 'then reaches the sheet straightening roller 10 or 10'directly; From the last diagonal straightening roller 11 or 11 'in the web transport direction, the web 2 or 2' then runs directly onto the first calming roller 18 or 18 '.

Schliesslich sei nochmals erwähnt, dass sowohl bei dem Ausführungsbeispiel gemäss den Fig. 1 und 2 als auch beim Ausführungsbeispiel gemäss Fig. 3 die komplette Warenbahn-Ausrichtvorrichtung (9 bzw. 9') innerhalb des Warenbahn-Einlaufteiles (3 bzw.3') der Spannmaschine (1 bzw. 1') angeordnet ist. Die zu dieser Ausrichtvorrichtung gehörende Schussfaden-Messeinrichtung (13 bzw. 13') ist dabei - wie sich ohne weiteres der entsprechenden Erläuterung der Steuereinrichtung anhand der Fig. 2 entnehmen lässt - kein reines Messglied, das lediglich der Anzeige der Schussfadenlagen dient, sondern - im Zusammenhang mit der erwähnten Steuereinrichtung - gleichzeitig auch eine Art Schussfadenregler, dessen Ausgangssignale über die Steuereinrichtung der jeweils zu verstellenden Richtwalze (Diagonal-Richtwalzen oder Bogen-Richtwalze) zugeführt werden, um mit Hilfe dieser Richtwalzen dann die Schussfäden der Warenbahn etwa rechtwinklig zu den Kettfäden auszurichten.Finally, it should be mentioned again that both in the embodiment according to FIGS. 1 and 2 and in the embodiment according to FIG. 3, the complete web alignment device (9 or 9 ') within the web inlet part (3 or 3') of the Tensioning machine (1 or 1 ') is arranged. The weft thread measuring device (13 or 13 ') belonging to this alignment device is - as can easily be seen from the corresponding explanation of the control device with reference to FIG. 2 - not a pure measuring element which only serves to display the weft thread positions, but rather - in In connection with the mentioned control device - at the same time also a kind of weft thread controller, the output signals of which are fed via the control device to the straightening roller to be adjusted in each case (diagonal straightening rollers or bow straightening roller) in order to then use these straightening rollers to align the weft threads of the web approximately at right angles to the warp threads .
