Description

Die Erfindung betrifft ein Verfahren zum kontinuierlichen Befeuchten, Glätten und kompressivem Schrumpfen von textiler Schlauchware, bei dem man die letztere mittels einem Breithalter in der Breite streckt, die derart gestreckte, in flachem Zustand sich befindende Ware befeuchtet und dann einer Glätt- und Schrumpfeinheit zuführt.The invention relates to a process for the continuous moistening, smoothing and compressive shrinking of textile tubular goods, in which the width is stretched by means of a spreader, which moistens the stretched, flat product and then feeds it to a smoothing and shrinking unit.

Es ist bereits ein Dämpfkalander für Maschenschlauchware bekannt, bei dem die zu behandelnde Schlauchware mittels einem Breithalter ausgebreitet, dann in einer Dämpfzone beidseitig bedämpft, anschliessend zwischen zwei Kalanderwalzen gepresst und dann abgetafelt wird. Diese Maschine weist jedoch den gravierenden Nachteil auf, dass infolge der Pressung zwischen den beiden Kalanderwalzen der Schrumpfwert der derart behandelten Ware verschlechtert wird.A steaming calender for tubular knitted fabrics is already known, in which the tubular goods to be treated are spread out by means of a spreader, then steamed on both sides in a steaming zone, then pressed between two calender rolls and then paneled. However, this machine has the serious disadvantage that the shrinkage value of the goods treated in this way deteriorates as a result of the pressure between the two calender rolls.

Es sind auch andere Dämpf- und Kompaktierkalander bekannt, bei denen die zu behandelnde Schlauchware mittels einem um eine Glätt- und Kompaktierwalze geführt wird (vgl. bspw. FR-A 2 242 504), die jedoch den Nachteil aufweisen, dass bei der dazu verwendeten Anordnung die Oberflächendichte des Transportbandes über seine gesamte Schlauchwaren-Transportstrecke praktisch konstant gleichbleibend ist. Dadurch ist jedoch bei vielen Schlauchwaren kein genügend kleiner Restschrumpfwert erreichbar, da die zu behandelnde Schlauchware über ihre gesamte Behandlungsstrecke praktisch unverrückbar auf einer immer gleich grossen, durch die Transportbandoberfläche gebildeten Auflagefläche aufliegt.Other steaming and compacting calenders are also known, in which the tubular goods to be treated are guided around a smoothing and compacting roller by means of a (see, for example, FR-A 2 242 504), but which have the disadvantage that they are used for this Arrangement the surface density of the conveyor belt is practically constant over its entire tubular goods transport route. As a result, however, a sufficiently small residual shrinkage value cannot be achieved with many tubular goods, since the tubular goods to be treated lie practically immovably over their entire treatment section on a support surface which is always of the same size and is formed by the conveyor belt surface.

Aufgabe der vorliegenden Erfindung ist insbesondere die Schaffung eines Verfahrens, welches diese Nachteile nicht aufweisen, das heisst mittels dem eine bedeutende Verbesserung des Schrumpfwertes der behandelten Ware erreicht werden kann, indem die Oberflächendichte des Transportbandes von der Aufnahmestelle der zu behandelnden Schlauchware bis zum Ende der Behandlung der letzteren variiert wird.The object of the present invention is, in particular, to create a method which does not have these disadvantages, that is to say by means of which a significant improvement in the shrinkage value of the treated goods can be achieved by the surface density of the conveyor belt from the receiving point of the tubular goods to be treated to the end of the treatment the latter is varied.

Diese Aufgabe wird bei einem Verfahren der eingangs genannten Art erfindungsgemäss dadurch gelöst, dass man die zu schrumpfende Ware auf die Aussenseite eines kontinuierlich umlaufenden, endlosen, aus einem Schrumpfband gebildeten Transportbandes anlegt, mittels letzterem in Eingriff mit der zylindrischen Aussenseite einer in der gleichen Richtung transportierenden Abstützwalze bringt und längs einem Teil des Umfanges der letzteren in Anlage an derselben um diese herum führt, und dann den gleichen Vorgang für die Gegenseite der in flachem Zustand sich befindenden Schlauchware in einer zweiten Glätt- und Schrumpfeinheit wiederholt, so dass die vorher mit dem Transportband in Eingriff gestandene Seite der zu behandelnden Ware nun in Eingriff mit der Aussenseite der Abstützwalze der zweiten Glätt- und Schrumpfeinheit gebracht wird, wobei man die zu schrumpfende Ware unmittelbar vor der Anlage auf der Aussenseite der Abstützwalze der ersten und/oder zweiten Glätt- und Schrumpfeinheit in einer um eine Umlenkwalze des Transportbandes entgegengesetzt zur Aussenseite der Abstützwalze gekrümmt verlaufenden Fläche und erst in diesem derart gekrümmten Bereich auf dem Transportband aufliegend von der Umlenkwalze auf die nachfolgende Abstützwalze abgibt, und dass das Transportband auf seiner inneren, gegen seine Umlenkwalzen zu gerichteten Seite aus einem im Betrieb praktisch nicht dehnbaren Grundträgermaterial besteht, auf dessen nach aussen gegen die zu behandelnde Ware zu gerichteter Seite eine elastische Schicht angeordnet ist.This object is achieved according to the invention in a method of the type mentioned at the outset by placing the goods to be shrunk on the outside of a continuously rotating, endless conveyor belt formed from a shrinking belt, by means of the latter in engagement with the cylindrical outside of a conveyor belt transporting in the same direction Support roller brings and runs along part of the circumference of the latter in abutment thereon, and then repeats the same process for the opposite side of the flat tubular material in a second smoothing and shrinking unit, so that the previously with the conveyor belt engaged side of the goods to be treated is now brought into engagement with the outside of the support roller of the second smoothing and shrinking unit, the goods to be shrinked being immediately in front of the system on the outside of the support roller of the first and / or second smoothing and shrinking egg unit in a surface that is curved around a deflection roller of the conveyor belt opposite to the outside of the support roller and only in this area curved in this way on the conveyor belt, rests on the conveyor roller from the deflection roller to the subsequent support roller, and that the conveyor belt on its inner side directed toward its deflection rollers consists of a base support material which is practically inextensible in operation, on the outside of which an elastic layer is arranged towards the side of the goods to be treated.

Zur Vermeidung der Erzeugung von Glanz auf der behandelten Ware ist es vorteilhaft, wenn die Umfangsgeschwindigkeit der Abstützwalze geringer ist als diejenige des zugeordneten Transportbandes.To avoid producing gloss on the treated goods, it is advantageous if the peripheral speed of the support roller is lower than that of the associated conveyor belt.

Vorteilhafte Weiterausgestaltungen des erfindungsgemässen Verfahrens sind Gegenstand der Ansprüche 2, 3 und 5 bis 12.Advantageous further developments of the method according to the invention are the subject of claims 2, 3 and 5 to 12.

Je nach Art der zu behandelnden Schlauchware kann es ausserdem vorteilhaft sein, wenn dem Transportband der ersten und/oder zweiten Glätt-und Schrumpfeinheit eine Befeuchtungs- und/oder Trocknungseinheit zugeordnet ist.Depending on the type of tubular material to be treated, it may also be advantageous if the conveyor belt of the first and / or second smoothing and shrinking unit is assigned a moistening and / or drying unit.

Nachstehend wird die Erfindung anhand der Zeichnung beispielsweise näher erläutert. Es zeigt:

  • Fig. 1 schematisch einen Längsschnitt durch eine beispielsweise Ausführungsform einer erfindungsgemässen Vorrichtung;
  • Fig. 2 in vergrössertem Massstab schematisch in Seitenansicht eine weitere beispielsweise Ausführungsform der beiden einander zugeordneten Glätt- und Schrumpfeinheit der in Fig. 1 dargestellten Vorrichtung; und
  • Fig. 3 und 4 in vergrössertem Massstab je einen Schnitt durch eine beispielsweise Ausführungsform des Transportbandes der in Fig. 1 dargestellten Vorrichtung.
The invention is explained in more detail below with reference to the drawing, for example. It shows:
  • Figure 1 schematically shows a longitudinal section through an example embodiment of an inventive device.
  • FIG. 2 on an enlarged scale, schematically in side view, a further exemplary embodiment of the two mutually assigned smoothing and shrinking units of the device shown in FIG. 1; and
  • 3 and 4 on an enlarged scale each a section through an example embodiment of the conveyor belt of the device shown in Fig. 1.

Wie aus Figur 1 ersichtlich, wird die zu behandelnde Maschenschlauchware 1 mittels einem Einzugswerk 2 aus einem Vorratsbehälter 3 abgezogen und über eine Rutsche 4 einem Breithalter 5 zugeführt, so dass die zu behandelnde Ware in ausgebreitetem Zustand durch eine Bedämpfungseinheit 6 hindurchgeführt werden kann. In dieser Bedämpfungseinheit wird die zu behandelnde Ware 1 von beiden Seiten gleichmässig und intensiv bedämpft, bis die derart behandelte Ware 1 etwa 10 bis 15 Gew.-% Feuchtigkeit aufgenommen hat.As can be seen from FIG. 1, the knitted tubular fabric 1 to be treated is drawn off from a storage container 3 by means of a feed mechanism 2 and fed to a spreader 5 via a slide 4, so that the goods to be treated can be passed through a damping unit 6 in the spread-out state. In this damping unit, the goods 1 to be treated are damped evenly and intensively from both sides until the goods 1 treated in this way have absorbed about 10 to 15% by weight of moisture.

Anschliessend wird die befeuchtete Schlauchware 1 mit Voreilung in möglichst losem Zustand in Eingriff mit der äusserst elastischen und dampfdurchlässigen Aussenseite eines kontinuierlich umlaufenden, auf seiner Aussenseite im Aufnahmebereich 9 aufgeweiteten, endlosen, aus einem sogenannten Schrumpfband gebildeten Transportband 7 in Eingriff gebracht, von letzterem an die verchromte zylindrische Aussenseite der in der gleichen Richtung der in der gleichen Richtung transportierenden Abstützwalze 8 angelegt und unter Verkürzung ihrer gegen die Schlauchware 1 zu gerichteten Abstützfläche 9 (siehe Fig. 4 und 5) längs einem Teil des Umfanges der Abstützwalze 8 und in Anlage an derselben um diese herum geführt. Dabei ist zur Vermeidung von Glanz auf der Warenoberfläche sowie zur Erzielung möglichst guter Schrumpfwerte die Umlaufgeschwindigkeit der Abstützwalze 8 normalerweise geringfügig geringer als die Umlaufgeschwindigkeit des über die Umlenkwalzen 10, 11 und 12 geführten Transportbandes 7. Die Drehachsen der Umlenk- sowie der Abstützwalze 8 und die Auflauflinie 17 der Warenbahn auf der Abstützwalze 8 liegen dabei in einer gemeinsamen Ebene 14.Subsequently, the moistened tubular fabric 1 with lead in the most loose state possible is brought into engagement with the extremely elastic and vapor-permeable outside of a continuously circulating endless conveyor belt 7 formed from a so-called shrink belt and expanded on the outside in the receiving area 9, from the latter to the latter Chromed cylindrical outer side of the support roller 8, which is transporting in the same direction, is created and its support surface 9 (see FIGS. 4 and 5) directed towards the tubular material 1 is shortened along a part of the circumference of the support roller 8 and in abutment against the same led around this. Here is ver Avoidance of gloss on the surface of the goods and to achieve the best possible shrinkage values, the rotational speed of the support roller 8 is normally slightly lower than the rotational speed of the conveyor belt 7 guided over the deflection rollers 10, 11 and 12. The axes of rotation of the deflection and support roller 8 and the run-up line 17 of the Goods web on the support roller 8 lie in a common plane 14.

Die Abstützwalze 8 wird auf eine Temperatur von etwa 110 bis 120°C aufgeheizt.The support roller 8 is heated to a temperature of about 110 to 120 ° C.

Um in der Bedämpfungsstation 6 möglichst wenig Flüssigkeit und Energie zu benötigen, kann es vorteilhaft sein, ein mindestens auf seiner Warenauflageseite mit einem Flüssigkeit speichernden Material versehenes Transportband 7 zu verwenden. Dabei kann es zur Erzielung eines universelleren Einsatzspektrums dieser Anlage vorteilhaft sein, wenn das derart ausgebildete Transportband 7 bei seinem Umlauf durch eine Befeuchtungs- und/oder Trocknungseinheit 15 hindurchläuft, um den gewünschten Befeuchtungsgrad des Transportbandes 7 automatisch geregelt genau steuern zu können.In order to require as little liquid and energy as possible in the damping station 6, it can be advantageous to use a conveyor belt 7 provided with a liquid-storing material at least on its goods support side. In order to achieve a more universal range of use of this system, it can be advantageous if the conveyor belt 7 designed in this way runs through a moistening and / or drying unit 15 in order to be able to control the desired degree of moistening of the conveyor belt 7 automatically and precisely in a controlled manner.

Nach Erzielung des gewünschten Glätt- und Schrumpfgrades wird zuerst das Transportband 7 ausser Eingriff mit der derart behandelten Schlauchware 1 gebracht und erst dann die letztere von der Abstützwalze 8 abgeleitet.After the desired degree of smoothing and shrinkage has been achieved, the conveyor belt 7 is first disengaged from the tubular material 1 treated in this way and only then is the latter derived from the support roller 8.

Der gleiche Arbeitsvorgang wird nun für die Gegenseite der in flachem Zustand sich befindenden Schlauchware 1 in einer zweiten nachfolgenden, gleich ausgebildeten Glätt- und Schrumpfeinheit wiederholt, so dass die vorher mit dem Transportband 7 der ersten Glätt- und Schrumpfeinheit in Eingriff gestandene Seite der zu behandelnden Schlauchware 1 nun in Eingriff mit der Aussenseite der ebenfalls beheizten Abstützwalze 8' der zweiten Glätt- und Schrumpfeinheit gebracht wird.The same operation is now repeated for the opposite side of the tubular goods 1 which are in the flat state in a second subsequent, identically designed smoothing and shrinking unit, so that the side of the treatment to be treated, which was previously engaged with the conveyor belt 7 of the first smoothing and shrinking unit Tubular goods 1 are now brought into engagement with the outside of the likewise heated support roller 8 'of the second smoothing and shrinking unit.

Nach dem Austritt aus der zweiten Glätt- und Schrumpfeinheit wird die derart behandelte Schlauchware 1 mit Hilfe einer Präzisionsabtafeleinrichtung 16 abgetafelt.After exiting the second smoothing and shrinking unit, the tubular goods 1 treated in this way are boarded with the aid of a precision table device 16.

Wie aus Figur 2 ersichtlich, wird die zu behandelnde Schlauchware 1 zur Verbesserung der Schrumpfwerte vor dem Einzug zwischen das Transportband 7 bzw. 7' und der zugeordneten Anpresswalze 8 bzw. 8' in einer um die erste, einen relativ geringen Aussendurchmesser aufweisenden Umlenkwalze 10 bzw. 10' entgegengesetzt gekrümmt verlaufenden Transportfläche, in welcher die gegen die aufzulegende Schlauchware 1 zu gerichtete Aussenseite 9 des Transportbandes 7 bzw. 7' stark vergrössert ist, mit dem letzteren in Eingriff gebracht. Bei der nachfolgenden Änderung der Krümmungsrichtung der Transportfläche nach dem ersten Auflagepunkt 17 bzw. 17' auf der Aussenseite der Anpresswalze 8 respektive 8' erfolgt eine starke Verkleinerung der mit der zu behandelnden Schlauchware in Eingriff stehenden Aussenseite 9 des auf dieser Seite ausserordentlich flexiblen und dehnbaren Transportbandes 7 respektive 7', und damit ein sehr guter Schrumpfeffekt.As can be seen from FIG. 2, the tubular material 1 to be treated is, in order to improve the shrinkage values, before being drawn in between the conveyor belt 7 or 7 ' and the associated pressure roller 8 or 8' in a deflection roller 10 or around the first, having a relatively small outside diameter 10 ', the transport surface which runs in the opposite curve and in which the outside 9 of the conveyor belt 7 or 7' which is directed towards the tubular goods 1 to be placed is greatly enlarged, is brought into engagement with the latter. In the subsequent change in the direction of curvature of the transport surface after the first support point 17 or 17 'on the outside of the pressure roller 8 or 8', the outside 9 of the extraordinarily flexible and stretchable conveyor belt, which is in engagement with the tubular goods to be treated, is greatly reduced 7 or 7 ', and thus a very good shrink effect.

Wie aus den Figuren 3 und 4 ersichtlich, besteht, das Transportband 7 bzw. 7' auf seiner inneren, gegen seine Umlenkwalzen 10, 11, 12 respektive 10', 11' und 12' zu gerichteten Seite aus einem im Betrieb praktisch nicht dehnbaren, dampfdurchlässigen mit Verstärkungsfäden armierten Grundträgermaterial 20, auf dessen nach aussen gegen die zu behandelnde Schlauchware 1 zu gerichteten Seite eine dampfdurchlässige elastische Tragschicht 21 angeordnet ist.As can be seen from FIGS. 3 and 4, the conveyor belt 7 or 7 'on its inner side directed towards its deflecting rollers 10, 11, 12 or 10', 11 'and 12' consists of a practically inextensible during operation, vapor-permeable base support material 20 reinforced with reinforcing threads, on the outside of which a vapor-permeable elastic base layer 21 is arranged toward the tubular material 1 to be treated.

Bei einer solchen Ausbildung des Transportbandes 7 bzw. 7' ist es ganz klar, dass die Schlauchwarenauflage- und -ergreiffläche des letzteren im gekrümmten Bereich 9 grösser ist als im geraden Teil 9', und in letzterem wiederum grösser ist als im nachfolgenden, gegenüber dem Bereich 9 umgekehrt gekrümmten Bereich 9". Dieser Effekt ist umso grösser, je grösser die Dicke d der elastischen, dampfdurchlässigen Schicht 21 des Transportbandes 7 respektive 7' und je kleiner der Durchmesser der Walzen 8 bzw. 8' und 10 respektiv 1 0' ist.With such a configuration of the conveyor belt 7 or 7 ', it is very clear that the tubular goods support and gripping surface of the latter is larger in the curved area 9 than in the straight part 9', and in the latter in turn is larger than in the following, compared to the Area 9 reversely curved area 9 ". This effect is greater the greater the thickness d of the elastic, vapor-permeable layer 21 of the conveyor belt 7 or 7 'and the smaller the diameter of the rollers 8 or 8' and 10 or 10 ' .

Bei der in Figur 3 dargestellten Ausführungsform besteht die elastische Schicht 21 aus einem dampfdurchlässigen Filz, und bei der in Figur 4 dargestellten Ausführungsform aus einem Flor.In the embodiment shown in FIG. 3, the elastic layer 21 consists of a vapor-permeable felt, and in the embodiment shown in FIG. 4 it consists of a pile.
