brauch ein Erzeugnis, das zugleich saugfähig und flüssigkeitsdicht ist. Gekrepptes Seidenpapier besitzt eine geeignete Saugfähigkeit. Eine Kunststoff-Folie ist dagegen flüssigkeitsdicht. Wenn eine Kunststoff-Folie so an das Papier laminiert wird, daß die Schichten ganzflächig aneinander haften, wird das Erzeugnis hart und steif. Selbst wenn die verwendeten Materialien weich und fallend sind, ist das fertige Verbunderzeugnis steif. Gleichzeitig nimmt auch die Saugfähigkeit des Papiers ab, da der Kunststoff in die Poren des Papiers dringt.need a product that is both absorbent and impermeable to liquids is. Creped tissue paper has a suitable absorbency. A plastic film is against it liquid-tight. When a plastic film is laminated to the paper in such a way that the layers come together over the entire surface stick, the product becomes hard and stiff. Even if the materials used are soft and falling, the finished composite product is stiff. At the same time, the absorbency of the paper decreases as the plastic does penetrates the pores of the paper.
Wenn die Befestigung der Schichten aneinander nur auf einem Teil ihrer Fläche, z.B. punktartig, erfolgt, wird die weiche und fallende Natur des fertigen Erzeugnisses beibehalten. If the layers are fastened to one another only on part of their surface, e.g. in a point-like manner, the maintain the soft and sloping nature of the finished product.
Bisher sind Plastfolien und Papier aneinander punktartig befestigt worden, indem die fertige Kunststoff-Folie an das Papier geklebt wurde.So far, plastic films and paper have been attached to each other in a point-like manner by attaching the finished plastic film the paper was glued.
Das Verfahren gemäß der Erfindung ist hauptsächlich dadurch gekennzeichnet, daß ein Kunststoff-Film oder dergleichen in geschmolzenem Zustand direkt zwischen Materialbahnen oder auf eine Seite einer Materialbahn zugeführt wird und die Befestigung der Schichten aneinander auf einem Teil ihrerThe method according to the invention is mainly characterized in that a plastic film or the like is in molten state is fed directly between webs of material or on one side of a web of material and the Attachment of the layers to one another on part of their

Fläche dadurch erfolgt, daß die Befestigungspunkte gepreßt werden, vorzugsweise, indem eine Preßwalze mit Reliefmuster und eine gegenüberliegende Gegenwalze verwendet werden.Surface is done in that the attachment points are pressed, preferably by using a press roller with a relief pattern and an opposing backing roll can be used.
Eine Preßwalze mit Reliefmuster wurde bisher bei der Extrusions !aminierung nicht verwendet. Bisher hat man immer eine möglichst ebene Preßwalze zu verwenden versucht, wobei man eine ebene und fehlerfreie Kunststoff-Folie erhält.A press roll with a relief pattern has not previously been used in extrusion amination. So far you always have one Tried to use as flat a press roll as possible, whereby a flat and flawless plastic film is obtained.
Die Herstellung der Kunststoff-Folie und ihre Laminierung an das Papier erfolgen also gemäß der vorliegenden Erfindung in einer Stufe.The manufacture of the plastic film and its lamination to the paper are therefore carried out in one step according to the present invention.
Es ist charakteristisch für das fertige Erzeugnis, daß die Schichten nur an den gepreßten Stellen miteinander in fester Berührung liegen. An den nicht festgepreßten Stellen befindet sich die Kunststoff-Folie locker zwischen den Oberflächenschichten. Hierdurch wird die gesamte ursprüngliche Saugfähigkeit des Papiers auch nach der Laminierung beibehalten und das Erzeugnis ist weicher, fallender, angenehmer und geräuschloser, als wenn dieselben Schichten ganzflächig festlaminiert sind.It is characteristic of the finished product that the layers are only firmly attached to one another at the pressed points Touch lying. The plastic film is loosely located between the surface layers in the areas that are not pressed tightly. As a result, the entire original absorbency of the paper is retained even after lamination and the product is softer, more sloping, more pleasant and noiseless than if the same layers were applied over the entire surface are firmly laminated.
Zum Verbinden der Schichten verwendet man im Gegensatz zum Zusammenkleben der Schichten keine Zusatzstoffe; dies istIn contrast to gluing the layers together, no additives are used to join the layers; This is

Eine Papierbahn 1 wird von der Abrollachse in den Preßspalt 5 zwischen einer Preßwalze 6 und einer Gegenwalze 7 geführt. Von einer oben befindlichen Düse 3 wird ein geschmolzener Kunststoff-Film H in denselben Walzenspalt geleitet. Die Temperatur des Kunststoffes ist hoch genug, um den Kunststoff in geschmolzenem Zustand zu halten, d.h. rund 250-34O0C. Eine zweite Papierbahn 2 wird von der entgegenliegenden Seite des Films 4 in den Walzenspalt geleitet.A paper web 1 is guided from the unwinding axis into the press nip 5 between a press roll 6 and an opposing roll 7. A molten plastic film H is fed into the same nip from a nozzle 3 located above. The temperature of the plastic is high enough to keep the plastic in the molten state, ie about 250-34O 0 C. A second paper web 2 is passed from the opposite side of the film 4 in the nip.
Die Preßwalze 6 ist mit einem Gummi bedeckt, in welchemThe press roller 6 is covered with a rubber in which

durch Fräsen ein Reliefmuster erzeugt ist. Hierbei werden die zu laminierenden Schichten an der Preßlinie gegeneinander gepreßt und aneinander befestigt. Das Preßen und die Befestigung finden aber nur auf einem Teil ihrer Fläche statt. Die Höhe des Reliefmusters kann z.B. 2 mm sein. Die Kanten der Musterfiguren werden vorteilhaft abgerundet, wobei der Preßvorgang sanfter ist und der geschmolzene Film zwischen den Walzen nicht beschädigt wird.a relief pattern is generated by milling. Here, the layers to be laminated are against each other on the press line pressed and fastened together. The pressing and the fastening take place, however, only on a part of their surface instead of. The height of the relief pattern can be 2 mm, for example. The edges of the model figures are advantageously rounded, with the pressing process is gentler and the molten film between the rollers is not damaged.
Der Gummi der Preßwalze mit Muster muß etwas härter sein als der Gummi an der Walze ohne Muster. Der geeignete Härtebereich beträgt 70-90°Shore. Ein geeigneter Liniendruck an der Preßlinie zwischen der Preßwalze 6 und der Gegenwalze 7 beträgt 5~15 kp/cm, berechnet pro drückenden Teil der Preßlinie. Das Muster der Preßwalze muß derartig sein, daß die tragende Fläche der Walze laufend ist, damit keine Vibrationen entstehen. Die Angabe, daß die tragende Fläche laufend sein soll, bedeutet hier, daß in jeder Drehlage der Preßwalze 6 Vorsprünge 10 an der Gegenwalze 7 anliegen. Gleichzeitig muß man danach streben, daß es möglichst wenig Bef es tigungs fläche gibt. Fig. 2, jnda"dfe Bewegungsrichtung der Laminierung mit dem Pfeil angegeben ist, gibt ein Beispiel für ein geeignetes Muster der Preßwalze. Die Erhöhungen der Walze sind mit 10 bezeichnet.The rubber on the press roll with a pattern must be a little harder than the rubber on the roll without a pattern. The appropriate hardness range is 70-90 ° Shore. A suitable line pressure on the press line between the press roll 6 and the counter roll 7 is 5 ~ 15 kgf / cm calculated per pressing part of the press line. The pattern of the press roll must be such that the supporting surface of the roller is running so that no vibrations arise. The indication that the load-bearing surface is ongoing is to be, here means that in each rotational position of the press roll 6 projections 10 rest against the counter roll 7. At the same time, one must strive to have as little mounting space as possible. Fig. 2, jnda "dfe direction of movement the lamination is indicated by the arrow, gives an example of a suitable pattern of the press roll. The increases of the roller are denoted by 10.

Eine Stützwalze 8 verhindert Biegungen der Gummiwalze 6. In der Stützwalze 8, in der Preßwalze 6 mit Muster sowie in der Kühlungswalze 7 mit Stahlmantel läuft eine Kühlflüssigkeit, vorzugsweise Wasser, um. Die Walzen werden so gekühlt, daß ihre Temperaturen etwa 5^5O°C betragen. Die Umfangsgeschwindigkeit kann bis zu 450 m/min, erreichen.A support roller 8 prevents bending of the rubber roller 6. In the support roller 8, in the press roller 6 with a pattern and in the cooling roller 7 with a steel jacket, a cooling liquid runs, preferably water to. The rollers are cooled so that their temperatures are about 50 ° C. The peripheral speed can reach up to 450 m / min.
Die Preßwalze 6 und die Kühlwalze 7 sind in bezug auf die Düse 3 vorzugsweise in einer solchen Lage, daß der Kunststoff-Film 4 in den Spalt 5 zwischen den'Walzen hauptsächlich in der Richtung der gemeinsamen Tangente der Walzen gelangt. Dabei haftet der Kunststoff vor dem Walzenspalt an keiner Papierbahn.The press roller 6 and the cooling roller 7 are with respect to the nozzle 3 preferably in such a position that the plastic film 4 mainly in the gap 5 between the rollers arrives in the direction of the common tangent of the rollers. The plastic adheres to the roller gap on any paper web.
