EP 88 850 286.1 SCA Development Aktiebolag Übersetzung der AnsprücheEP 88 850 286.1 SCA Development Aktiebolag Translation of the claims 1. Verfahren zum Herstellen eines symmetrischen, dreilagigen Papiers aus zwei ungleichartigen Materialien, von denen eines die oberen Schichten des Papiers und das andere Material die Zwischenschicht des Papiers bildet, dadurch gekennzeichnet, daß die oberen Schichten und im wesentlichen die Hälfte des Gewichts für die Zwischenschicht durch gemeinsame Ausbildung in zwei getrennten Zuführkästen ausgebildet werden, und daß die zwei getrennt ausgebildeten Schichten bei einem Trockenfeststoffgehalt von nicht über 12% miteinander verbunden werden.1. A method of making a symmetrical three-ply paper from two dissimilar materials, one of which forms the upper layers of the paper and the other material forms the intermediate layer of the paper, characterized in that the upper layers and substantially half of the weight for the intermediate layer are formed by co-formation in two separate feed boxes, and in that the two separately formed layers are bonded together at a dry solids content of not more than 12%. 2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß die Zwischenschicht bei einer niederen Konzentration von 0,1 - 1,0 % im Zuführkasten und die äußere Schicht bei einer höheren Konzentration von 0,3 - 1,2 % ausgebildet wird.2. Process according to claim 1, characterized in that the intermediate layer is formed at a lower concentration of 0.1 - 1.0 % in the feed box and the outer layer is formed at a higher concentration of 0.3 - 1.2 % . 3. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß die oberen Schichten in den gemeinsam ausgebildeten Schichten bei der nachfolgenden getrennten Formung gegeneinander gedrückt werden.3. Method according to claim 1, characterized in that the upper layers in the jointly formed layers are pressed against each other during the subsequent separate forming. 4. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß das Material zum Ausbilden der äußeren Schicht einen Anteil von kurzen Fasern von 80 - 100 %, möglicherweise mit hohem Schlag- bzw. Rührgrad, und die Zwischenschicht einen Anteil von langen Fasern von 70 - 100 % enthält.4. Process according to claim 1, characterized in that the material for forming the outer layer contains a proportion of short fibers of 80 - 100 %, possibly with a high degree of agitation, and the intermediate layer contains a proportion of long fibers of 70 - 100%. 5. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß dem Material zum Ausbilden der Zwischenschicht ein Füllmittel in einer Menge von wenigstens 10 % zugegeben wi rd.5. Process according to claim 1, characterized in that a filler in an amount of at least 10% is added to the material for forming the intermediate layer.
