Abstract

The invention relates to a method for setting a uniform and specific tension in running material webs, such as textile webs or the like, guided with width stretching through a treatment space, especially a dryer, in which the material webs are first introduced without width stretching into tensioning elements which are arranged on tensioning chains guided in chain tracks, and are subsequently width-stretched by a width adjustment of the chain tracks, and is aimed at guaranteeing an always specific tension in all the parts of the material web. For this, it is proposed, according to the invention, to guide the material webs (10) through the treatment station so as to be held elastically flexibly in the width-stretching direction, for example in that the tensioning elements (14), such as needle bars or tenter clips, arranged on carriers (13) on the tensioning chains and held in an end position in the width-stretching direction of the material web, are mounted on the carriers in an elastically displaceable manner.

Description

Die Erfindung betrifft eine Anordnung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to an arrangement according to the preamble of patent claim 1.

Sie geht von einer Vorrichtung aus, die durch die GB-A-2 136 465 bekannt geworden ist. Bei dieser Vorrichtung ist die Breitenverstellvorrichtung als Spindel ausgebildet, welche zwei den Kettenbahnen zugeordnete Abschnitte mit gegensinnigen Gewinden aufweist. Die Spindel ist mittels eines Motors drehbar. Sie wirkt in axialer Richtung mit einer der Warenspannung entsprechenden Kraft auf eine Kraftmeßdose ein, deren Meßsignal den Motor in dem Sinne steuert, daß die Warenspannung innerhalb vorgegebener Grenzen gehalten wird.It is based on a device known from GB-A-2 136 465. In this device, the width adjustment device is designed as a spindle which has two sections with opposing threads which are assigned to the chain tracks. The spindle can be rotated by means of a motor. It acts in the axial direction with a force corresponding to the fabric tension on a load cell, the measurement signal of which controls the motor in the sense that the fabric tension is kept within predetermined limits.

Durch die DE-C-1 629 384 ist schon eine Vorrichtung zum Spannen von bewegten Bahnen, insbesondere Kunststoffolienbahnen, bekannt, bei der an der Kette Spannkluppen in Bahnrichtung elastisch angelenkt und quer zur Bahnrichtung elastisch abgestützt sind. Bei einem Ausführungsbeispiel ist jede Spannkluppe an einer Stange befestigt, die in einem mit der Kette verbundenen Führungskörper geführt und axial, d.h. in Breitenspannrichtung, gegen eine Druckfeder verstellbar ist.From DE-C-1 629 384 a device for tensioning moving webs, in particular plastic film webs, is already known, in which tension clips are articulated on the chain in the web direction and elastically supported transversely to the web direction. In one embodiment, each clamp is attached to a rod which is guided in a guide body connected to the chain and axially, i.e. in the width direction, adjustable against a compression spring.

Durch die Erfindung soll die Aufgabe gelöst werden, immer definierte Spannungen in allen Warenbahnteilen zu gewährleisten.The object of the invention is to ensure that tensions are always defined in all parts of the web.

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

Die Zeichnung dient zur Erläuterung der Erfindung anhand eines Ausführungsbeispiels.

Fig. 1

Fig. 2
zeigt die Anordnung in einer Draufsicht.
The drawing serves to explain the invention using an exemplary embodiment.
Fig. 1
shows an arrangement according to the invention in side view.
Fig. 2
shows the arrangement in a plan view.

Bei den Darstellung ist die Warenbahn mit 10, die Kettenbahn mit 11, die Spannkette mit 12, der Träger für das Spannelement an der Spannkette mit 13 und das Spannelement, welches in der Zeichnung als Nadelleiste dargestellt ist, mit 14 bezeichnet.In the illustration, the web of material with 10, the chain conveyor with 11, the tension chain with 12, the support for the tensioning element on the tension chain with 13 and the tensioning element, which is shown in the drawing as a needle bar, with 14.

An der in der Kettenbahn 11 laufenden Spannkette 12 ist ein Träger 13 für das Spannelement 14 angebracht. Das Spannelement ist an einem Zwischenträger 15 befestigt, der durch eine Feder 16 in einer Endstellung am Träger 13 gehalten ist und dadurch eine federnde Aufhängung der Warenbahn 10 in Breitspannrichtung bewirkt. Gemäß Fig. 2 ist der Zwischenträger 15 schwenkbar am Träger 13 angebracht, so daß die angedeutete Schrägstellung der Nadelleiste möglich ist, die zur Vergleichmäßigung der Spannung in der Warenbahn beiträgt. Fig. 1 zeigt auch die Anordnung von Sensoren 21, 22 für die Überwachung der Lage der Nadelleiste 14 in bezug auf ihre Endstellungen im Verschiebeweg. Durch die Sensoren 21, 22 wird die Breitenverstellung der Kettenbahnen gesteuert.A carrier 13 for the tensioning element 14 is attached to the tension chain 12 running in the chain track 11. The tensioning element is fastened to an intermediate support 15 which is held in an end position on the support 13 by a spring 16 and thereby causes a resilient suspension of the web 10 in the wide-span direction. 2, the intermediate carrier 15 is pivotally attached to the carrier 13, so that the indicated inclined position of the needle bar is possible, which contributes to the equalization of the tension in the web. Fig. 1 also shows the arrangement of sensors 21, 22 for monitoring the position of the needle bar 14 with respect to their end positions in the displacement path. The width adjustment of the chain tracks is controlled by the sensors 21, 22.
