Definitions
- the invention relates to a tensioning machine with a horizontal drying zone for the continuous treatment of a web held between chain links consisting of chain links, the two longitudinal edges of which can be detachably fastened to the chain links in a coupling zone, each of the chain links having pivot pins to be coupled to a neighboring chain link, and wherein the tensioning chains - horizontally in the drying zone - are assigned guide rails with supporting slideways for sliding blocks of the chain links.
- the tension chains are endless. They are deflected - seen in the web transport direction or chain running direction - in front of the coupling zone (single needle field) and after a decoupling zone (needle field), the axes of which are perpendicular or parallel to the adjacent goods area and the goods transport direction. In the case of conventional plane clamping frames, this is referred to as a horizontal or vertical chain deflection, that is to say a deflection of the chain in a plane parallel or perpendicular to the plane of the web.
- tenter frame dryers with tension chains consisting of chain links for a fabric web spread out between the tension chains, for example a textile fabric web.
- the web is held at its two longitudinal edges in needles or clips through a drying and optionally fixing zone.
- the web edges are needled or clipped on in a pin-on or clipping zone, in short Coupling zone.
- An example of such a tenter frame is described in EP 00 73 915 B1.
- the tensioning chains run in or on guide rails, which take up the weight of the tensioning chain and the carried web on the one hand and the transverse tension exerted on the web (on the other hand, transverse to the web transport direction).
- the guide rails are essentially horizontal. They have load-bearing slideways (slide slides) for sliding blocks of the chain links, which support the weight of the chain (including the material path if necessary).
- Each guide rail also has a tensioning roller or slideway that absorbs the transverse tension exerted on the web.
- An example of a tension chain equipped with corresponding sliding blocks or sliding elements is described in DE 33 33 938 A1.
- the sliding blocks themselves conventionally have a flat sliding surface, which is moved relative to the respective, also flat supporting slide.
- the present stretching machine should be suitable for drying a pretreated web, for example coated on both sides in a pretreatment zone, or a web coated and / or dyed in the pretreatment zone and consisting of glass fibers or containing glass fibers.
- Coated webs of goods may generally only be touched then, e.g. deflected on rollers - when the coating has dried.
- Glass fibers often keep colors worse than the surface of rollers usually used in textile machines, so that the latter should only touch the surface of the glass fiber webs when the applied substance has dried.
- the guide rail which is horizontal in the horizontal drying zone and curved at the transition to the pretreatment zone, also has flat support slideways in its flat areas, and support slideways curved to the same extent in its curved areas.
- the sliding blocks of the chain links can be assigned to the supporting slideways.
- the sliding blocks have conventionally flat sliding surfaces that slide on the supporting slide tracks during operation.
- the sliding surfaces in question should be just like the (horizontal) supporting slideways so that the friction between the sliding block and the slideway takes place over a wide area, i.e. not in a line or point. If, however, the slideways in the deflection area of the guide rail are curved - that is, not flat -, the sliding blocks touch the slideways in this area in a point-like or linear manner, so that a relatively strong abrasion can result.
- the invention has for its object to form a tensioning frame chain slidably carried in the guide rails on slideways in such a way that the associated sliding blocks of the chain links touch the supporting slideways of the guide rails flatly both in their flat (horizontal) region and in their quarter-circle deflection region.
- the individual sliding block according to the invention lies flat against both the flat parts and the curved parts of the supporting slide tracks.
- the rounded region of the sliding surface assigned to the curved deflection zone is expediently located approximately in the middle of its length, viewed in the chain longitudinal direction, on the individual sliding block.
- the radius of curvature of this rounded central zone of the sliding block surface should have approximately the same value as the radius of curvature of the deflection zone of the guide rails.
- the invention preferably relates to a tensioning machine with a horizontal drying zone and a vertical pretreatment zone for a web stretched out between tension chains designed as slide chains.
- the tension chains are moved from the vertical to the horizontal position in a deflection zone.
- the sliding surfaces of the supporting sliding blocks attached to the chain are arranged in three successive zones in the transport direction, namely one flat edge zone, a curved middle zone and a second flat edge zone divided.
- FIG. 1 shows a cross section through a device according to the invention with a horizontal drying zone and an upstream vertical coating unit

- the web 2 is fed from roll 4 via web tension controller 5 into the coating unit 1.
- the material web 2 is coated on both sides and drawn essentially vertically upwards through a single-needle field 6 (coupling zone).
- the web edges are attached to tension chains 7, which run in guide rails 8.
- the chain links of the tensioning chains 7 can be equipped with conventional needle bars or those already used as standard.
- the single-needle field 6 has a vertical length of approximately 2 m following the coating unit 1.
- a quarter-circular deflection zone 9 adjoins the single-needle field 6, the radius of curvature R of which in the exemplary embodiment should be approximately 3 m.
- the deflection zone 9 can be horizontal at its upper end 10 immediately or after passing through, e.g. 2 m long, inspection zone 11 open into the drying fields 12, 13 etc. of a conventional stenter dryer 3.
- the latter can usually have one, two, three or more such drying fields 12, 13.
- the drying fields are followed by a run-out zone 14, for example with a needling field 15 and web tension regulator 16 and take-up roll 17.
- the base 18 of the tenter dryer 3 is approximately 5.5 m above the factory base 19 (on which the coating unit 1 is also located).
- the greatest height (here the fans 20) of the system is approx. 9 m. Factory halls of this height are common.
- the web 2 can be supported in the region of the deflection zone 9 by an air cushion 21.
- FIG. 2 and 3 show an enlarged view of the tension chain 7 according to FIG. 1 with rollers for absorbing the transverse forces.
- the tension chain consists of chain links 25 with so-called inner links 24 and chain links 23 with so-called outer links 26.
- the chain links 23 and 25 are held together by the connecting bolts 22.
- 3 needle strips 27 are attached to the tabs 24 Stigt.
- Each needle bar 27 has a plurality of needles 28, in which the longitudinal edge 29 (FIG. 4) of the web 2 is suspended.
- the needle bars 27 can be connected to the inner plates 24 by means of brackets 30.
- the tension chain 7 runs in operation in a transport direction 33 and is tensioned in this direction.
- horizontal transverse forces acting on the chain from the web 2 to be processed are intercepted with the aid of rollers 34 which run on correspondingly shaped roller rails 35 of the guide rails 8 (FIG. 3).

- the support body 40 (with a chain attached) runs from the slidable surfaces 31 (see also FIG. 3). It is attached to the support body 40 which also receives the bracket 30 of the needle bar 27 in such a way that the chain 7 is slidably mounted on its way through the tensioning machine.
- the supporting slideways 32 lie horizontally like the guide rails 8 as a whole. If, however, for some reason the guide rails 8 are to be suitable for deflecting the tension chain 7 from the horizontal position into a vertical position, this deflection rich a curvature of both the guide rails 8 and the slideways 32 required.

position in a deflection area. In order to ensure that the fulcrum slides bearing
the respective tensing chain flatly rest upon the associated supporting slide
tracks in the horizontal, flat area and in the curved area of the guide tracks,
the sliding surfaces of the supporting fulcrum slides disposed on the chain are
divided into three successive zones in the direction of transport and a lower
flat edge zone. .

Beschreibung:Description:
Die Erfindung betrifft eine Spannmaschine mit horizontaler Trocknungszone zum fortlaufenden Behandeln einer zwischen aus Kettengliedern bestehenden Spannketten ausgebreitet gehaltenen Warenbahn, deren beide Längskanten in einer Koppelzone lösbar an den Kettengliedern zu befestigen sind, wobei jedes der Kettenglieder schwenkbar mit je einem Nachbarkettenglied zu koppelnde Verbindungsbolzen besitzt und wobei den Spannketten - in der Trocknungszone horizontal - Führungsschienen mit Traggleitbahnen für Gleitsteine der Kettenglieder zugeordnet sind.The invention relates to a tensioning machine with a horizontal drying zone for the continuous treatment of a web held between chain links consisting of chain links, the two longitudinal edges of which can be detachably fastened to the chain links in a coupling zone, each of the chain links having pivot pins to be coupled to a neighboring chain link, and wherein the tensioning chains - horizontally in the drying zone - are assigned guide rails with supporting slideways for sliding blocks of the chain links.
Die Spannketten sind endlos. Sie werden - gesehen in Bahntransportrichtung bzw. Kettenlaufrichtung - vor der Koppelzone (Einnadelfeld) und nach einer Entkoppelzone (Ausnadelfeld) um Wellen umgelenkt, deren Achsen senkrecht oder parallel zur angrenzenden Warenfläche und zur Warentransportrichtung stehen. Bei herkömmlichen Planspannrahmen spricht man in diesem Zusammenhang von einer horizontalen bzw. vertikalen Kettenumlenkung, das heißt von einer Umlenkung der Kette in einer Ebene parallel oder senkrecht zur Warenbahnebene.The tension chains are endless. They are deflected - seen in the web transport direction or chain running direction - in front of the coupling zone (single needle field) and after a decoupling zone (needle field), the axes of which are perpendicular or parallel to the adjacent goods area and the goods transport direction. In the case of conventional plane clamping frames, this is referred to as a horizontal or vertical chain deflection, that is to say a deflection of the chain in a plane parallel or perpendicular to the plane of the web.
Es gibt Spannrahmentrockner mit aus Kettengliedern bestehenden Spannketten für eine zwischen den Spannketten ausgebreitete Warenbahn, z.B. textile Stoffbahn. Die Bahn wird an ihren beiden Längsrändern in Nadeln oder Kluppen gehalten durch eine Trocken- und gegebenenfalls Fixierzone geführt. Das Aufnadeln oder Einkluppen der Bahnkanten erfolgt in einer Aufnadel- bzw. Einkluppzone, kurz
Koppelzone. Ein Beispiel eines solchen Spannrahmens wird beschrieben in EP 00 73 915 B1.There are tenter frame dryers with tension chains consisting of chain links for a fabric web spread out between the tension chains, for example a textile fabric web. The web is held at its two longitudinal edges in needles or clips through a drying and optionally fixing zone. The web edges are needled or clipped on in a pin-on or clipping zone, in short Coupling zone. An example of such a tenter frame is described in EP 00 73 915 B1.
In der Regel laufen die Spannketten in bzw. auf Führungsschienen, die das Gewicht der Spannkette und der mitgeführten Warenbahn einerseits sowie die auf die Warenbahn ausgeübte Querspannung (quer zur Bahntransportrichtung) andererseits aufnehmen. Bei einem normalen Planspannrahmen (mit einer einzigen Behandlungsebene) liegen die Führungsschienen im Wesentlichen horizontal. Sie besitzen tragende Gleitbahnen (Traggleitbahnen) für Gleitsteine der Kettenglieder, welche das Gewicht der Kette (gegebenenfalls einschließlich Warenbahn) tragen. Außerdem gehört zu jeder Führungsschiene eine Spannroll- bzw. -gleitbahn, die die auf die Warenbahn jeweils ausgeübte Querspannung aufnimmt. Ein Beispiel einer mit entsprechenden Gleitsteinen bzw. Gleitelementen ausgestatteten Spannkette wird beschrieben in DE 33 33 938 A1. Die Gleitsteine selbst besitzen herkömmlich eine ebene Gleitfläche, die relativ zu der jeweiligen, ebenfalls ebenen Traggleitbahn bewegt wird.As a rule, the tensioning chains run in or on guide rails, which take up the weight of the tensioning chain and the carried web on the one hand and the transverse tension exerted on the web (on the other hand, transverse to the web transport direction). In a normal plane clamping frame (with a single treatment level), the guide rails are essentially horizontal. They have load-bearing slideways (slide slides) for sliding blocks of the chain links, which support the weight of the chain (including the material path if necessary). Each guide rail also has a tensioning roller or slideway that absorbs the transverse tension exerted on the web. An example of a tension chain equipped with corresponding sliding blocks or sliding elements is described in DE 33 33 938 A1. The sliding blocks themselves conventionally have a flat sliding surface, which is moved relative to the respective, also flat supporting slide.
Die vorliegende Spannmaschine soll geeignet sein zum Trocknen einer vorbehandelten, beispielsweise in einer Vorbehandlungszone beidseitig beschichteten, Warenbahn bzw. einer in der Vorbehandlungszone beschichteten und/oder gefärbten, aus Glasfasern bestehenden oder Glasfaser enthaltenden Warenbahn. Beschichtete Warenbahnen dürfen in der Regel erst dann berührt, - z.B. an Walzen umgelenkt - werden, wenn die Beschichtung getrocknet ist. Glasfasern halten Farben häufig schlechter als die Oberfläche üblicherweise in Textilmaschinen verwendeter Walzen, so daß letztere die Fläche der Glasfaser-Warenbahnen erst berühren sollen, wenn die aufgebrachte Substanz getrocknet ist.The present stretching machine should be suitable for drying a pretreated web, for example coated on both sides in a pretreatment zone, or a web coated and / or dyed in the pretreatment zone and consisting of glass fibers or containing glass fibers. Coated webs of goods may generally only be touched then, e.g. deflected on rollers - when the coating has dried. Glass fibers often keep colors worse than the surface of rollers usually used in textile machines, so that the latter should only touch the surface of the glass fiber webs when the applied substance has dried.
In Einrichtungen, in denen eine laufende Warenbahn auf beiden Flächen zu beschichten ist, wird die Bahn senkrecht von unten nach oben durch das Beschich- tungsaggregat gezogen. Die senkrechte Warenführung hat den Vorteil, daß die Beschichtungsverhältnisse auf beiden Warenflächen gleich sind - dies im Gegensatz zu einer horizontalen Warenführung. Da die frisch beschichtete Oberfläche
der Bahn erst nach dem Trocknen berührt werden darf, wird die Ware nach dem Auftauchen aus dem Beschichtungsaggregat durch einen senkrecht über Letzterem angeordnete Trockner geleitet. Ganz ähnlich wird beim Trocknen der Glasfaser-Bahnen verfahren.In facilities in which a running web of goods is to be coated on both surfaces, the web is pulled vertically through the coating unit from bottom to top. Vertical goods routing has the advantage that the coating conditions on both goods surfaces are the same - in contrast to horizontal goods routing. Because the freshly coated surface the web may only be touched after drying, the goods are passed out of the coating unit through a dryer arranged vertically above the latter. The procedure for drying the fiberglass sheets is very similar.
Bei manchen Qualitäten von vertikal aus der Vorbehandlung kommenden Warenbahnen besteht die Notwendigkeit, die Bahnbreite während der Trocknung zu kontrollieren. Zu diesem Zweck wird die Warenbahn in den beschriebenen Spannketten aufgenommen, auf eine bestimmte Breite gespannt und einem vertikalen Trockner zugeführt. Da man Trockner wegen meist zu geringer Höhe der jeweiligen Fabrikhalle nicht beliebig hoch bauen kann, wurde vorgeschlagen, die Spannketten mit bereits darin aufgenommener, beiderseits beschichteter Warenbahn durch eine viertel-kreisförmige Umlenkzone - 90°-Umlenkzone - der Spannketten auf gekrümmten bzw. gebogenen Führungsschienen (von der Vertikalen in die Horizontale) mit glattem Übergang in eine horizontale Position einer Trocknungszone zu bringen. Die gekrümmten Führungsschienen besitzen ebenso (vorzugsweise konzentrisch) gekrümmte Traggleitbahnen.For some qualities of webs that come vertically from the pretreatment, there is a need to control the web width during drying. For this purpose, the web is taken up in the tension chains described, stretched to a certain width and fed to a vertical dryer. Since it is not possible to build dryers of any height due to the fact that the height of the respective factory hall is too low, it has been proposed that the tension chains with the web of material already incorporated in it and coated on both sides through a quarter-circular deflection zone - 90 ° deflection zone - of the tension chains on curved or curved guide rails (from vertical to horizontal) with a smooth transition to a horizontal position of a drying zone. The curved guide rails also have (preferably concentrically) curved support slideways.
Im Ergebnis besitzt die in der horizontalen Trocknungszone horizontale und am Übergang zur Vorbehandlungszone gekrümmte Führungsschiene in ihren ebenen Bereichen ebenso ebene Traggleitbahnen sowie in ihren gekrümmten Bereichen in gleichem Maße gekrümmte Traggleitbahnen. Den Traggleitbahnen können die Gleitsteine der Kettenglieder zugeordnet werden.As a result, the guide rail, which is horizontal in the horizontal drying zone and curved at the transition to the pretreatment zone, also has flat support slideways in its flat areas, and support slideways curved to the same extent in its curved areas. The sliding blocks of the chain links can be assigned to the supporting slideways.
Die Gleitsteine besitzen - wie gesagt - herkömmlich ebene Gleitflächen, die bei Betrieb auf den Traggleitbahnen gleiten. Die fraglichen Gleitflächen sollen eben - wie die (horizontalen) Traggleitbahnen - sein, damit die Reibung zwischen Gleitstein und Gleitbahn flächig, also nicht linien- oder punktförmig, erfolgt. Wenn nun aber die Gleitbahnen in dem Umlenkbereich der Führungsschiene gekrümmt - also nicht eben - sind, berühren die Gleitsteine die Gleitbahnen in diesem Bereich punkt- oder linienförmig, so daß sich ein relativ starker Abrieb ergeben kann. Man könnte die Gleitfläche der Gleitsteine zwar so hohlzylindrisch formen (z.B. durch
Hohlschleifen), daß die Gleitsteine im gekrümmten Umlenkbereich der Gleitbahnen der Form von deren Krümmung angepaßt sind und daher flächig anliegen. Dann wäre jedoch in Kauf zu nehmen, daß auf den ebenen Teilen der Gleitbahnen nur die Kanten der hohlzylindrischen Form anliegen und entsprechend schnell abnutzen.As already mentioned, the sliding blocks have conventionally flat sliding surfaces that slide on the supporting slide tracks during operation. The sliding surfaces in question should be just like the (horizontal) supporting slideways so that the friction between the sliding block and the slideway takes place over a wide area, i.e. not in a line or point. If, however, the slideways in the deflection area of the guide rail are curved - that is, not flat -, the sliding blocks touch the slideways in this area in a point-like or linear manner, so that a relatively strong abrasion can result. One could shape the sliding surface of the sliding blocks so hollow cylindrical (e.g. by Hollow grinding) that the sliding blocks in the curved deflection area of the slideways are adapted to the shape of their curvature and therefore lie flat. Then, however, it would have to be accepted that only the edges of the hollow cylindrical shape rest on the flat parts of the slideways and wear out correspondingly quickly.
Der Erfindung liegt die Aufgabe zugrunde, eine gleitend in den Führungsschienen auf Gleitbahnen getragene Spannrahmenkette so auszubilden, daß die zugehörigen Gleitsteine der Kettenglieder die Traggleitbahnen der Führungsschienen sowohl in deren ebenen (horizontalen) Bereich als auch in deren viertelkreisförmigen Umlenkbereich flächig berühren.The invention has for its object to form a tensioning frame chain slidably carried in the guide rails on slideways in such a way that the associated sliding blocks of the chain links touch the supporting slideways of the guide rails flatly both in their flat (horizontal) region and in their quarter-circle deflection region.
Die erfindungsgemäße Lösung besteht für die eingangs genannte Spannmaschine darin, daß bei zwischen vertikaler Vorbehandlungszone und horizontaler Trocknungszone eingeschalteter Viertelkreis-Umlenkzone der Führungsschienen und Traggleitbahnen die den Letzteren zuzuwendenden Gleitflächen der Gleitsteine eine der Krümmung der Umlenkzone zum flächigen Anliegen angepaßt geformte Mittelzone und in Bahn-Transportrichtung vor und hinter (beiderseits) der Mittelzone je eine ebene Teilgleitfläche zum glatten Anliegen an den horizontalen Teilen der Traggleitbahnen besitzen. Einige Verbesserungen und weitere Ausgestaltungen der Erfindung werden in den Unteransprüchen beschrieben.The solution according to the invention for the tensioning machine mentioned at the outset is that when the quarter circle deflection zone of the guide rails and supporting slide tracks is switched on between the vertical pretreatment zone and the horizontal drying zone, the sliding surfaces of the sliding blocks to be turned towards the latter have a shaped central zone adapted to the curvature of the deflection zone for flat contact and in the direction of web transport In front and behind (on both sides) of the central zone each have a flat partial sliding surface for smooth contact with the horizontal parts of the supporting slideways. Some improvements and further refinements of the invention are described in the subclaims.
Der einzelne erfindungsgemäße Gleitstein liegt sowohl an den ebenen Teilen als auch an den gekrümmten Teilen der Traggleitbahnen flächig an. Das wird dadurch erreicht, daß die die Kette tragenden Gleitsteine eine geteilte Gleitfläche besitzen, deren Teile sowohl im gekrümmten Bereich als auch im ebenen Bereich der Traggleitbahnen mit einem erheblichen Anteil ihrer Gleitfläche flächig anliegen. Zweckmäßig befindet sich am einzelnen Gleitstein der der gekrümmten Umlenkzone zugeordnete gerundete Bereich der Gleitfläche etwa in der Mitte von deren Länge, gesehen in Kettenlängsrichtung. Der Krümmungsradius dieser gerundeten Mittelzone der Gleitsteinfläche soll annähernd denselben Wert wie der Krümmungsradius der Umlenkzone der Führungsschienen besitzen. Um die Flächenpressung im
gekrümmten Teil und im ebenen Teil gleich groß zu halten, ist es vorteilhaft, die Länge des gerundeten Teils der Gleitfläche etwa gleich groß zu gestalten wie die Summe der Längenabschnitte der ebenen Teile der Gleitfläche.The individual sliding block according to the invention lies flat against both the flat parts and the curved parts of the supporting slide tracks. This is achieved in that the sliding blocks carrying the chain have a divided sliding surface, the parts of which lie flat in the curved region as well as in the flat region of the supporting slide tracks with a considerable proportion of their sliding surface. The rounded region of the sliding surface assigned to the curved deflection zone is expediently located approximately in the middle of its length, viewed in the chain longitudinal direction, on the individual sliding block. The radius of curvature of this rounded central zone of the sliding block surface should have approximately the same value as the radius of curvature of the deflection zone of the guide rails. To the surface pressure in To keep the curved part and the same size in the flat part, it is advantageous to make the length of the rounded part of the sliding surface approximately the same size as the sum of the length sections of the flat parts of the sliding surface.
Vorzugsweise betrifft die Erfindung eine Spannmaschine mit horizontaler Trocknungszone und vertikaler Vorbehandlungszone für eine zwischen als Gleitketten ausgebildeten Spannketten ausgebreitete Warenbahn. Die Spannketten werden in einer Umlenkzone aus der vertikalen in die horizontale Position gebracht. Um zu erreichen, daß die die jeweilige Spannkette tragenden Gleitsteine sowohl im horizontalen, ebenen Bereich als auch im gekrümmten Bereich der Führungsschienen flächig an den zugehörigen Traggleitbahnen anliegen, werden die Gleitflächen der an der Kette angebrachten tragenden Gleitsteine in drei in Transportrichtung aufeinanderfolgenden Zonen, nämlich eine ebene Randzone, eine gekrümmte Mittelzone und eine zweite ebene Randzone unterteilt.The invention preferably relates to a tensioning machine with a horizontal drying zone and a vertical pretreatment zone for a web stretched out between tension chains designed as slide chains. The tension chains are moved from the vertical to the horizontal position in a deflection zone. In order to ensure that the sliding blocks carrying the respective tension chain lie flat against the associated supporting slide tracks both in the horizontal, flat area and in the curved area of the guide rails, the sliding surfaces of the supporting sliding blocks attached to the chain are arranged in three successive zones in the transport direction, namely one flat edge zone, a curved middle zone and a second flat edge zone divided.

Die Warenbahn 2 wird ab Rolle 4 über Bahnspannungsregler 5 in das Beschichtungsaggregat 1 geleitet. Dort wird die Warenbahn 2 auf beiden Seiten beschichtet und im Wesentlichen vertikal nach oben durch ein Einnadelfeld 6 (Koppelzone) gezogen. Hier werden die Warenbahnkanten an Spannketten 7, welche in Führungsschienen 8 laufen, befestigt.

Bei den angegebenen Maßen liegt der Boden 18 des Spannrahmentrockners 3 etwa 5,5 m über dem Fabrikboden 19 (auf dem auch das Beschichtungsaggregat 1 steht), während die größte Höhe (hier die Ventilatoren 20) der Anlage ca. 9 m beträgt. Fabrikhallen dieser Höhe sind üblich. Die Bahn 2 kann im Bereich der Umlenkzone 9 von einem Luftkissen 21 unterstützt werden.A quarter-circular deflection zone 9 adjoins the single-needle field 6, the radius of curvature R of which in the exemplary embodiment should be approximately 3 m. The deflection zone 9 can be horizontal at its upper end 10 immediately or after passing through, e.g. 2 m long, inspection zone 11 open into the drying fields 12, 13 etc. of a conventional stenter dryer 3. The latter can usually have one, two, three or more such drying fields 12, 13. In the exemplary embodiment, the drying fields are followed by a run-out zone 14, for example with a needling field 15 and web tension regulator 16 and take-up roll 17. With the dimensions given, the base 18 of the tenter dryer 3 is approximately 5.5 m above the factory base 19 (on which the coating unit 1 is also located). , while the greatest height (here the fans 20) of the system is approx. 9 m. Factory halls of this height are common. The web 2 can be supported in the region of the deflection zone 9 by an air cushion 21.
Die Fig. 2 und 3 zeigen eine vergrößerte Darstellung der Spannkette 7 nach Fig. 1 mit Rollen zur Aufnahme der Querkräfte. In Fig. 2 werden zwei Verbindungsbolzen 22 der Spannkette 7 abgebildet. Die Spannkette besteht aus Kettengliedern 25 mit sogenannten Innenlaschen 24 und Kettengliedern 23 mit sogenannten Außenlaschen 26. Die Kettenglieder 23 und 25 werden durch die Verbindungsbolzen 22 zusammengehalten. Nach Fig. 3 werden an den Laschen 24 Nadelleisten 27 befe-
stigt. Jede Nadelleiste 27 besitzt mehrere Nadeln 28, in denen die Längskante 29 (Fig. 4) der Warenbahn 2 eingehängt wird. Die Nadelleisten 27 können über Bügel 30 mit den Innenlaschen 24 verbunden werden.2 and 3 show an enlarged view of the tension chain 7 according to FIG. 1 with rollers for absorbing the transverse forces. In Fig. 2, two connecting bolts 22 of the tension chain 7 are shown. The tension chain consists of chain links 25 with so-called inner links 24 and chain links 23 with so-called outer links 26. The chain links 23 and 25 are held together by the connecting bolts 22. 3 needle strips 27 are attached to the tabs 24 Stigt. Each needle bar 27 has a plurality of needles 28, in which the longitudinal edge 29 (FIG. 4) of the web 2 is suspended. The needle bars 27 can be connected to the inner plates 24 by means of brackets 30.
Die Spannkette 7 läuft bei Betrieb in einer Transportrichtung 33 und wird in dieser Richtung gespannt. Zugleich auf die Kette von der zu bearbeitenden Warenbahn 2 her wirkende horizontale Querkräfte werden mit Hilfe von Laufrollen 34, die an entsprechend geformten Rollschienen 35 der Führungsschienen 8 ablaufen, abgefangen (Fig. 3). Die Laufrollen 34 werden nach Fig. 2 über insgesamt mit 36 bezeichnete Gleitlager auf Stahlbuchsen 37, die die Bolzen 22 koaxial umfassen, gelagert. Im Ausführungsbeispiel wird der Verbindungsbolzen 22 in der jeweiligen Stahlbuchse 37 mit Hilfe einer Kunststoffbuchse 38 schmierfrei gelagert.The tension chain 7 runs in operation in a transport direction 33 and is tensioned in this direction. At the same time, horizontal transverse forces acting on the chain from the web 2 to be processed are intercepted with the aid of rollers 34 which run on correspondingly shaped roller rails 35 of the guide rails 8 (FIG. 3). The rollers 34 are supported according to FIG. 2 via a total of 36 plain bearings on steel bushings 37 which coaxially comprise the bolts 22. In the exemplary embodiment, the connecting pin 22 is mounted in the respective steel bushing 37 with the aid of a plastic bushing 38 without lubrication.
Fig. 4 zeigt einen vertikalen Schnitt durch ein Spannkettenglied quer zur Transport- richtung 33. In der Kette nach Fig. 4 werden sowohl für die Aufnahme der Querkräfte als auch für die Aufnahme der Gewichtskräfte Gleitlager vorgesehen. Die Transportkette nach Fig. 4 enthält Verbindungsbolzen 22, welche mit unteren und oberen Innenlaschen 24 verbunden sind.FIG. 4 shows a vertical section through a tension chain link transversely to the direction of transport 33. In the chain according to FIG. 4, plain bearings are provided both for absorbing the transverse forces and for absorbing the weight forces. 4 contains connecting bolts 22 which are connected to lower and upper inner links 24.
Im Rahmen der vorliegenden Erfindung sind vor allem zwei Traggleitbahnen 32 von Bedeutung, die ebenfalls an einem Teil der Führungsschiene 8 zu befestigen sind. Die Gleitbahnen 32 nehmen im Ausführungsbeispiel die Gewichtskräfte der Kette 7 auf. An den Gleitbahnen 32 läuft der Tragkörper 40 (mit anhängender Kette) auf den Gleitflächen 31 ab (siehe auch Fig. 3). Er wird derart an dem auch den Bügel 30 der Nadelleiste 27 aufnehmenden Tragkörper 40 befestigt, daß die Kette 7 auf ihrem Weg durch die Spannmaschine überall gleitend gelagert ist.In the context of the present invention, two supporting slideways 32 are particularly important, which are also to be fastened to a part of the guide rail 8. In the exemplary embodiment, the slideways 32 absorb the weight forces of the chain 7. On the slideways 32, the support body 40 (with a chain attached) runs from the slidable surfaces 31 (see also FIG. 3). It is attached to the support body 40 which also receives the bracket 30 of the needle bar 27 in such a way that the chain 7 is slidably mounted on its way through the tensioning machine.
Die Traggleitbahnen 32 liegen bei herkömmlichen Planspannrahmen horizontal wie die Führungsschienen 8 insgesamt. Wenn jedoch die Führungsschienen 8 aus irgendwelchen Gründen dazu geeignet sein sollen, die Spannkette 7 von der horizontalen Position in eine vertikale Position umzulenken, ist in diesem Umlenkbe-
reich eine Krümmung sowohl der Führungsschienen 8 als auch der Gleitbahnen 32 erforderlich.In conventional plane clamping frames, the supporting slideways 32 lie horizontally like the guide rails 8 as a whole. If, however, for some reason the guide rails 8 are to be suitable for deflecting the tension chain 7 from the horizontal position into a vertical position, this deflection rich a curvature of both the guide rails 8 and the slideways 32 required.
Während die Gleitfläche 31 nach Fig. 5 herkömmlich durchweg genauso eben wie die Traggleitbahn 32 selbst ist, wird erfindungsgemäß die Gleitfläche 31 unterteilt. Sie besteht nach Fig. 5 aus drei in Transportrichtung 33 aufeinanderfolgenden Teilen, einem ebenen Bereich (ebene erste Teilgleitfläche 51), eine zylindrische Mittelzone (gekrümmte Teilgleitfläche 52) mit dem Krümmungsradius R und einem zweiten ebenen Bereich (ebene zweite Teilgleitfläche 53). Vorzugsweise hat der Bereich 52 in Transportrichtung 33 ungefähr die gleiche Länge wie die Summe der Bereiche 51 plus 53. Bei Betrieb wirken die ebenen Teilgleitflächen 51 und 53 als Auflageflächen überall dort, wo auch die Traggleitbahn 32 eben ist.While the sliding surface 31 according to FIG. 5 is conventionally as flat as the supporting slide 32 itself, the sliding surface 31 is divided according to the invention. 5 consists of three parts in succession in the transport direction 33, a flat region (flat first partial sliding surface 51), a cylindrical central zone (curved partial sliding surface 52) with the radius of curvature R and a second flat region (flat second partial sliding surface 53). The area 52 in the direction of transport 33 preferably has approximately the same length as the sum of the areas 51 plus 53. In operation, the flat partial sliding surfaces 51 and 53 act as contact surfaces wherever the supporting slide 32 is also flat.
