Description
Die Erfindung bezieht sich auf eine Vorrichtung der nach dem Oberbegriff des Anspruchs I entsprechenden Art, die durch die DE-PS 1 80 269 bekannt istThe invention relates to a device according to the preamble of claim I. Kind that is known from DE-PS 1 80 269
Bei der bekannten Ausführungsform kommt der Mitläufer nach dem Auftauchen aus dem in dem Behälter befindlichen Behandlungsmittel sogleich mit der Bahn in dem Walzspalt in Berührung. Die übertragene Menge des Auftragsmittels ist dadurch gegeben, wieviel Auftragsmittel an dem Mitläufer anhaften kann. Eine solche Menge ist in vielen Bedarfsfällen nocii zu groß. Außerdem ist der Auftrag Ober die Breite der Bahn je nach d< .) Zufälligkeiten des Aufnahmevermögens des Mit'äufers ungleichmäßig.In the known embodiment, the follower comes after surfacing from the in the Container located treatment agent immediately with the web in the nip in contact. the The amount of application agent transferred is given by the amount of application agent on the follower can adhere. Such an amount is not too large in many cases. Besides, the job is Over the width of the track depending on d <.) Randomness of the absorption capacity of the fellow traveler unevenly.
Der Erfindung liegt die Aufgai: · zugrunde, eine Vorrichtung der dem Oberbegriff entsprechenden Art so auszugestalten, daß ein Auftrag von kleineren Mengen eines Auftragsmitlels gleichmäßig möglich ist.The invention is based on: a device of the type corresponding to the preamble to be designed in such a way that an application of smaller amounts of an application agent is possible evenly.
Diese Aufgabe wird durch die im Patentanspruch angegebene Vorrichtung gelöst.This object is achieved by the device specified in the claim.
In dem vorgeschalteten Walzspalt kann eine Abquetschung des Mitläufers stattfinden, durch die der Feuchtigkeitsgehalt so weit abgesenkt wird, daß nur noch ganz geringe Mengen des Auftragsmittels auf die Bahn übertragen werden. Gleichzeitig findet in dem vorgeschalteten Walzspalt eine Vergleichmäßigung der flächenmäßigen Verteilung des Auftragsmittels auf den Mitläufer statt, bevor dieser mit der Bahn zusammengebracht wird. Für den Abquetschvorgang ist kein weiteres Walzenpaar, sondern lediglich eine zusätzliche Wake erforderlich, die mit der umschlungenen <Valze zusammenwirkt.Squeezing can occur in the upstream roll gap of the follower take place, through which the moisture content is lowered so far that only very small amounts of the application agent are still transferred to the web. At the same time takes place in that upstream roll gap an equalization of the areal distribution of the application agent on the Followers take place before this is brought together with the train will. There is no further pair of rollers for the squeezing process, just an additional one Wake required, those with the entwined <Valze cooperates.
In der Zeichnung ist ein Ausführungsoeispiel der Erfindung schematisch dargestellt. Die einzige Figur zeigt einen vertikalen Längsschnitt durch die Vorrichtung. In the drawing, an exemplary embodiment of the invention is shown schematically. The only figure shows a vertical longitudinal section through the device.
Die Bahn 1 läuft im Sinne des Pfeiles durch die Vorrichtung und von oben über eine Umlenkrolle 2 durch einen Walzspalt 3, der von der Walze 4 und der durchbiegungssteuerbaren Walze 5 gebildet wird, die vorgesehen ist, um einen gleichmäßigen Abquetschdruck im Walzspalt 3 zu erzielen. Nach den Verlassen des Walzspalts 3 läuft die Warenbahn 1 über die Rolle 6 aus der Vorrichtung aus.The web 1 runs in the direction of the arrow through the device and from above over a deflection roller 2 by a roll gap 3, which is formed by the roll 4 and the deflection-controllable roll 5, the is provided in order to achieve a uniform squeeze pressure in the roll gap 3. After leaving of the roll gap 3, the web 1 runs out of the device via the roller 6.
Um die Walze 4 ist ein endlos umlaufender Mitläufer 7 geschlungen, der eine gemäß der Zeichnung nach unten verlaufende Schleife 14 bildet, in deren unterem Scheitel eine Rolle 8 angeordnet ist, die, wie durch den Pfeil 9 angedeutet, nsch unten belastet ist. Im Bereich des unteren Scheitels taucht der Mitläufer 7 in das in dem Behälter 10 befindliche Auftragsmittel 11 ein und nimmt dieses bei seinem Umlauf mit.An endlessly rotating idler 7 is looped around the roller 4, the one according to the drawing forms running down loop 14, in the lower apex, a roller 8 is arranged, which, as by the Arrow 9 indicated, nsch is loaded below. In the area of the lower apex, the follower 7 dips into the application means 11 located in the container 10 and takes this with him as it circulates.
Gegen die Walze 4 liegt außer der Walze 5 noch die Walze 12 an, so daß ein weiterer Walzspalt 13 geb;ldet ist, durch den der Mitläufer 7 bei seinem Umlauf im angedeuteten Sinne vor dem Erreichen des Walzspalts 3 hindurchläuft und in dem der in dem Behälter 10 stark mit dem Auftragsmittel 11 getränkte Mitläufer 7 vorabgequetscht werden kann, um einen definierten und verringerten Feuchtigkeitsgehalt zu erhalten. Mit diesem Feuchtigkeitsgehalt wird der Mitläufer 7 in dem Walzspalt 3 mit der Bahn 1 doublieri und überträgt dabei einen Teil seiner Feuchtigkeit auf die Bahn 1. Die Größe dieses Teils wird durch die separat einstellbaren Liniendnicke in 'en Walzspalten 3 und 13 gesteuert.In addition to the roller 5, the roller 12 rests against the roller 4, so that a further roller gap 13 is formed ; Is ldet through which the follower 7 runs in the indicated sense before reaching the roll gap 3 and in which the follower 7 heavily soaked with the application agent 11 in the container 10 can be squeezed in advance in order to obtain a defined and reduced moisture content. With this moisture content, the follower 7 is doubled with the web 1 in the roll gap 3 and transfers part of its moisture to the web 1. The size of this part is controlled by the separately adjustable line thickness in the roll gaps 3 and 13.
