Abstract

Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zum Dehnen von Schlauchware (1) mittels eingeblasener Druckluft (9) wobei die Zuführungsgeschwindigkeit und/oder die Abzugsgeschwindigkeit der Schlauchware geregelt wird. Man erreicht auf diese Weise eine sehr gleichmäßige Dehnung der Schlauchware ohne Beeinträchtigung der Oberfläche.The invention relates to a method and a device for stretching tubular goods (1) by means of blown compressed air (9), the feed rate and / or the withdrawal speed of the tubular goods being regulated. In this way, a very uniform stretching of the tubular goods is achieved without impairing the surface.

Description

Die Erfindung betrifft ein Verfahren entsprechend dem Oberbegriff des Anspruches 1 sowie eine Vorrichtung zur Durchführung dieses Verfahrens.The invention relates to a method according to the preamble of claim 1 and an apparatus for performing this method.

Um Textilschlauchware in ihrer Dimensionsstabilität zu verbessern, ist es bekannt, die Schlauchware im nassen Zustand zu dehnen und anschließend zu trocknen. Dieses Dehnen von Schlauchware erfolgt bisher mit Hilfe von mechanischen Dehneinrichtungen (Breithaltern), in denen die Schlauchware im Kantenbereich eingeklemmt und durch allmähliches Auseinanderführen der beiden Klemmzonen in der Breite gedehnt wird.In order to improve the dimensional stability of textile tubular goods, it is known to stretch the tubular goods in the wet state and then to dry them. This stretching of tubular goods has so far been carried out with the aid of mechanical stretching devices (spreader bars) in which the tubular goods are clamped in the edge area and the width is expanded by gradually moving the two clamping zones apart.

Nachteilig ist bei diesem bekannten Verfahren vorallem, daß die Schlauchware in unmittelbarer Nähe des eingeklemmten Kantenbereiches durch die hier herrschenden größeren Zugkräfte wesentlich mehr gedehnt wird als im mittleren Bereich zwischen den eingeklemmten Zonen. Die Schlauchware wird bei diesem bekannten Verfahren somit ungleichmäßig gedehnt, so daß keine optimale Verbesserung der Dimensionsstabilität erreicht wird.A disadvantage of this known method is above all that the tubular fabric in the immediate vicinity of the pinched edge area is stretched considerably more by the greater tensile forces prevailing here than in the middle area between the pinched zones. The tubular fabric is thus stretched unevenly in this known method, so that no optimal improvement in dimensional stability is achieved.

Für einen anderen Zweck, nämlich zum Verlegen von strang- bzw. schlauchförmigem Textilgut bei einer Naßbehandlung (wie Färben, Waschen, Spülen) ist es ferner bekannt, in die Schlauchware Luft einzublasen, um dadurch den Strang zu öffnen und ge- bildete Falten zu verlegen (EP-A- 19 101). Hierbei werden jedoch keine über das bloße öffnen des Stranges hinausgehenden Dehnungskräfte auf die Ware ausgeübt.For another purpose, namely for laying stranded or tubular textile material in wet treatment (such as dyeing, washing, rinsing), it is also known to add air to the tubular fabric inflate, to thereby open the strand and g e - formed pleats to move (EP-A-19101). However, no expansion forces beyond the mere opening of the strand are exerted on the goods.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der im Oberbegriff des Anspruches 1 genannten Art dahin weiterzuentwickeln, daß ohne eine die Oberfläche der Ware beeinträchtigende mechanische Einwirkung ein gleichmäßiges Dehnen der Schlauchware über die gesamte Schlauchbreite erreicht wird.The invention has for its object to further develop a method of the type mentioned in the preamble of claim 1 that a uniform stretching of the tubular goods is achieved over the entire hose width without a mechanical action affecting the surface of the goods.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing features of claim 1.

Bei dem erfindungsgemäßen Verfahren wird die Schlauchware mit Voreilung in die Dehnungszone eingeführt. Durch eine gegenüber der Abzugsgeschwindigkeit größere Zuführgeschwindigkeit wird somit mehr Schlauchware in die Dehnungszone eingeführt, als aus dieser abgezogen. In die Schlauchware wird ferner in der Dehnungszone Druckluft (in ausreichender Menge und mit genügendem Druck) eingedüst, wobei die Schlauchware am Anfang und am Ende der Dehnungszone gegen einen Luftaustritt abgedichtet wird.In the method according to the invention, the tubular goods are introduced into the stretch zone with lead. Due to a higher feed speed compared to the take-off speed, more tubular goods are thus introduced into the stretch zone than are drawn off from this. Compressed air (in sufficient quantity and with sufficient pressure) is also injected into the tubular fabric in the expansion zone, the tubular fabric being sealed against air leakage at the beginning and at the end of the expansion zone.

Bei den der Erfindung zugrundeliegenden Versuchen hat sich nun herausgestellt, daß man das Ausmaß der Dehnung der Schlauchware sehr feinfühlig und genau durch Regelung der Zuführungsgeschwindigkeit und/oder der Abzugsgeschwindigkeit beeinflussen kann. Mißt man die Breite der Schlauchware nach der Dehnungszone, so läßt sich durch Regelung der Zuführungs- und/oder Abzugsgeschwindigkeit erreichen, daß die Schlauchware genau auf die gewünschte Breite gedehnt wird. Im Unterschied zu den bisher bekannten mechanischen Dehnverfahren wird bei dem erfindungsgemäßen pneumatischen Dehnverfahren eine absolut gleichmäßige Dehnung der Schlauchware über die gesamte Breite erreicht, da an allen Umfangsstellen gleiche Dehnungskräfte angreifen und keine Zonen der Schlauchware eingeklemmt sind.In the experiments on which the invention is based, it has now been found that the The extent of the elongation of the tubular goods can be influenced very delicately and precisely by regulating the feed speed and / or the take-off speed. If the width of the tubular goods is measured after the stretching zone, it can be achieved by regulating the feed and / or take-off speed that the tubular goods are stretched exactly to the desired width. In contrast to the previously known mechanical stretching methods, the pneumatic stretching method according to the invention achieves an absolutely uniform stretching of the tubular goods over the entire width, since the same stretching forces act on all circumferential points and no zones of the tubular goods are pinched.

Zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche und werden im Zusammenhang mit der Erläuterung eines in der Zeichnung veranschaulichten Ausführungsbeispieles beschrieben.Appropriate embodiments of the invention are the subject of the dependent claims and are described in connection with the explanation of an exemplary embodiment illustrated in the drawing.

Die schematisch dargestellte Vorrichtung dient zum Dehnen von Schlauchware 1 in einer Dehnungszone 2, deren Anfang und Ende durch je ein Walzenpaar 3,4 bzw. 5,6 begrenzt ist. Jeweils eine Walze jedes Walzenpaares, nämlich die Walze 4 bzw. 6 ist angetriebenl'Die Walze 4 des am Anfang der Dehnungszone vorgesehenen Walzenpaares ist darüber hinaus regelbar.The device shown schematically serves for stretching tubular goods 1 in a stretching zone 2, the beginning and end of which are delimited by a pair of rollers 3, 4 and 5, respectively. In each case one roller of each pair of rollers, namely the roller 4 or 6 is driven. The roller 4 of the pair of rollers provided at the beginning of the expansion zone can also be regulated.

Die Walzen 3 und 4 sind in einemvorzugsweise mit Wasser gefüllten Flüssigkeitstrog 7 angeordnet, in den die Schlauchware 1 über eine Umlenkwalze 8 eingeführt ist.The rollers 3 and 4 are arranged in a liquid trough 7, preferably filled with water, into which the tubular material 1 is introduced via a deflection roller 8.

Zur Eindüsung von Druckluft in die Schlauchware 1 ist am Anfang der Dehnungszone 2 ein an der Außenseite der Schlauchware 1 anliegendes Düsenelement 9 vorgesehen, das durch eine Pumpe 10 mit Druckluft beaufschlagt wird und wenigstens eine (nicht dargestellte) Düsenöffnung enthält. Das Düsenelement 9 kann entweder stationär angeordnet sein oder mit der Schlauchware lose mitlaufen. Im letzteren Falle können die durch die Schlauchware 1 nicht abgedeckten Düsenöffnungen des Düsenelementes 9 entweder durch eine ortsfeste Dichtung abgedichtet sein oder (bei Inkaufnahme eines gewissen Verlustes an Druckluft) offen bleiben.In order to inject compressed air into the tubular fabric 1, a nozzle element 9, which bears on the outside of the tubular fabric 1, is provided at the beginning of the expansion zone 2 and is pressurized with compressed air by a pump 10 and contains at least one (not shown) nozzle opening. The nozzle element 9 can either be arranged stationary or run loose with the tubular goods. In the latter case, the nozzle openings of the nozzle element 9 which are not covered by the tubular material 1 can either be sealed by a fixed seal or can remain open (if a certain loss of compressed air is accepted).

Mit Abstand vor den am Ende der Dehnungszone angeordneten Walzen 5 und 6 sind zwei Führungswalzen 11,12 angeordnet, die bewirken, daß die aufgeblasene Schlauchware 1 mit einem definierten, nicht zu großen öffnungswinkel in das Walzenpaar 5,6 einläuft. Dadurch wird die Bildung von Falten in der Schlauchware 1 beim Passieren des Walzenpaares 5,6 verhindert.At a distance from the rollers 5 and 6 arranged at the end of the expansion zone, two guide rollers 11, 12 are arranged, which cause the inflated tubular fabric 1 to enter the roller pair 5, 6 with a defined, not too large opening angle. This prevents the formation of wrinkles in the tubular fabric 1 when passing through the pair of rollers 5, 6.

Nach Verlassen der Dehnungszone 2 passiert die Schlauchware 1 beispielsweise eine Haspel 13.After leaving the expansion zone 2, the tubular goods 1 pass through a reel 13, for example.

Zwischen dem Walzenpaar 5,6 und der Haspel 13 ist die Schlauchware 1 flächig (eben) geführt und passiert eine Meßeinrichtung 14, die die Breite der in der Dehnungszone 2 gedehnten, nunmehr doppellagig liegenden Schlauchware 1 mißt.Between the pair of rollers 5, 6 and the reel 13, the tubular fabric 1 is guided flatly (flat) and passes through a measuring device 14 which measures the width of the tubular fabric 1, which is now stretched out in the expansion zone 2 and is now double-layered.

Das erfindungsgemäße Verfahren kann mit der dargestellten Vorrichtung beispielsweise in der Weise durchgeführt werden, daß die Walze 6, die die Schlauchware 1 aus der Dehnungszone 2 abzieht, mit einer festen Drehzahl angetrieben wird, so daß die Schlauchware die Dehnungszone mit einer vorgegebenen Abzugsgeschwindigkeit verläßt. Die am Anfang der Dehnungszone 2 vorgesehene Walze 4 wird demgegenüber in Abhängigkeit vom Signal der Meßeinrichtung 14 mit einer solchen Drehzahl angetrieben, daß die Schlauchware 1 mit einer gegenüber der Abzugsgeschwindigkeit höheren Zuführgeschwindigkeit in die Dehnungszone 2 einläuft. Wird außerdem über das Düsenelement 9 Druckluft in ausreichender Menge und mit genügendem Druck in die Schlauchware 1 eingedüst, so kann man durch Regelung der Antriebsgeschwindigkeit der Walze 4 das Ausmaß der in der Dehnungszone 2 erfolgenden Dehnung der Schlauchware 1 sehr feinfühlig und genau (sowie mit ganz geringer Ansprechverzögerung) beeinflussen. Erhöht man die Zuführgeschwindigkeit, so vergrößert sich die Dehnung und umgekehrt. Die im Flüssigkeitstrog 7 auf die Schlauchware 1 aufgebrachte Flüssigkeit dichtet in der Dehnungszone 2 den Innenraum der Schlauchware 1 gegen einen Luftaustritt ab. Am Anfang und am Ende der Dehnungszone 2 bewirken ferner die Walzen 3, 4 bzw. 5, 6 die erforderliche Abdichtung der Dehnungszone.The method according to the invention can be carried out with the device shown, for example, in such a way that the roller 6, which pulls the tubular fabric 1 out of the expansion zone 2, is driven at a fixed speed, so that the tubular fabric leaves the expansion zone at a predetermined take-off speed. In contrast, the roller 4 provided at the beginning of the stretching zone 2 is driven at such a speed as a function of the signal from the measuring device 14 that the tubular fabric 1 runs into the stretching zone 2 at a higher feed speed than the take-off speed. If compressed air is also injected into the tubular fabric 1 in sufficient quantity and with sufficient pressure via the nozzle element 9, the degree of expansion of the tubular fabric 1 occurring in the expansion zone 2 can be adjusted very delicately and precisely (as well as completely) by regulating the drive speed of the roller 4 low response delay). If the feed rate is increased, the elongation increases and vice versa. The liquid applied to the tubular goods 1 in the liquid trough 7 seals in the expansion zone 2 the interior of the tubular goods 1 against air leakage. At the beginning and at the end of the expansion zone 2, the rollers 3, 4 and 5, 6 also effect the required sealing of the expansion zone.

Zur weiteren Erläuterung der Erfindung diene folgendes Beispiel:

  • Eine im Schlauch gestrickte Baumwoll-Feinrippware kommt als Rohware mit 36 cm Schlauchbreite in die Veredelung. Die gewünschte Schlauchbreite der Fertigware ist 30 cm.
The following example serves to further explain the invention:
  • A fine-knit cotton fabric knitted in a tube is processed as a raw material with a tube width of 36 cm. The desired hose width of the finished product is 30 cm.

Die Ware wird in einer Bleichanlage behandelt, anschließend gespült und liegt dann aufgrund von Längsdehnung in einer Schlauchbreite von 25 cm vor.The goods are treated in a bleaching plant, then rinsed and are then in a tube width of 25 cm due to their longitudinal expansion.

Diese Ware 1 läuft mit 20 m/min in die von den Walzen 3 und 4 gebildete Fuge ein. Das Flottenniveau im Trog 7 ist so gewählt, daß die aus der Fuge austretende Ware sich wiederum voll mit Wasser benetzen kann.This product 1 runs at 20 m / min into the joint formed by the rollers 3 and 4. The liquor level in the trough 7 is chosen so that the goods emerging from the joint can in turn be fully wetted with water.

Durch die Pumpe 10 wird Luft mit einem Druck von ca. 1000 mm WS über ein feststehendes Rohr, das mit einer Bohrung von 3 mm versehen ist, in den nassen, mit Flüssigkeit bedeckten Schlauch geführt. Der Schlauch füllt sich dadurch mit Luft. Die Walzen 11 und 12 sorgen dafür, daß der Schlauch ohne Bogenverzug zu der von den Walzen 5 und 6 gebildeten Fuge gelangt. Das von den Walzen 5 und 6 gebildete Walzenpaar läuft mit einer Geschwindigkeit von 17 m/min. Dadurch ergibt sich eine Geschwindigkeitsdifferenz zwischen den beiden transportierenden Walzenpaaren von 15 %.The pump 10 feeds air with a pressure of approx. 1000 mm WS through a fixed pipe, which is provided with a bore of 3 mm, into the wet, liquid-covered hose. This will fill the hose with air. The rollers 11 and 12 ensure that the hose reaches the joint formed by the rollers 5 and 6 without warping. That from reels 5 and 6 formed pair of rollers runs at a speed of 17 m / min. This results in a speed difference of 15% between the two pairs of rollers.

Zwischen den Walzen 5 und 6 wird die Ware scharf abgequetscht, so daß sie einen minimalen Wassergehalt aufweist, beispielsweise 70 %. Die Ware passiert die Meßeinrichtung 14 mit einer Schlauchbreite von 31 cm. Bei der anschließenden Trocknung schrumpft die Ware in Länge und Breite noch geringfügig nach, so daß die gewünschte Endbreite von 30 cm erreicht wird und die Warenlänge geringe Restkrumpfwerte aufweist.The goods are squeezed sharply between the rollers 5 and 6 so that they have a minimal water content, for example 70%. The goods pass the measuring device 14 with a hose width of 31 cm. During the subsequent drying, the length and width of the goods shrink slightly, so that the desired final width of 30 cm is reached and the length of the goods has low residual shrinkage values.
