Abstract

Die Erfindung betrifft einen Stoffauflauf einer mit mindestens einem Gap- und/oder Hybridformer ausgestatteten Papier- oder Kartonmaschine mit einem Turbulenzeinsatz (2) mit einer Vielzahl an Faserstoffsuspension führenden Kanälen (5) mit hydraulischen Durchmessern, die sich von einem vorletzten hydraulischen Durchmesser D2 auf einen letzten hydraulischen Durchmesser D1 erweitern, wobei der Beginn der letzten Erweiterung einen Abstand L1 zum Ende des Turbulenzeinsatzes aufweist.
Die Erfindung ist dadurch gekennzeichnet, dass der Turbulenzeinsatz (2) die folgenden Bedingungen erfüllt: L1 D1 = a * expb*D1 D2 mit a = 10,252 und b = 0,457, wobei eine maximale Abweichung des L1/D1 - Wertes von +30%/-60%, vorzugsweise +20%/-40%, vorzugsweise +10%/-20%, erlaubt ist.
