Belagpapierstreifenabschnitte die als Führungsflächen vorgesehenen Schneidführungsflanken beim Schneidvorgang im Zusammenwirken mit einer an einer als Gegenwalze ausgebildeten Saugwalze vorgesehenen Schneidkante zunächst in Kontakt gebracht werden, wodurch die die Schneidkante der Gegenwalze berührenden Schneidführungsflanken der Schneidwalze an dieser Schneidkante zum Beispiel eines Messers der Saugwalze (Gegenwalze) beim Eintauchen in eine Nut der Gegenwalze entlang gleiten, so dass unter Rotation der Schneidwalze und der mit der Schneidwalze zusammenwirkenden Saugwalze der Schneidbereich des Messerkörpers des Messers und die Schneidkante der Saugwalze einander angenähert werden.The invention is based on the idea that a cutting roller of a padding device is formed with one or more knives, whereby the cutting guide edges provided as guide surfaces during cutting of webbing strips in material web strip sections or covering paper strip sections during the cutting process in cooperation with a provided on a suction roll as a counter-rotating cutting edge first whereby the cutting guide edges of the cutting roller contacting the cutting edge of the backing roll slide along this cutting edge of, for example, a knife of the suction roll (counter roll) when immersed in a groove of the backing roll so that the cutting roll and the suction roll cooperating with the cutting roll rotate the cutting area of the knife body of the knife and the cutting edge of the suction roll are approximated to each other.
Dabei ist vorzugweise vorgesehen, dass der Schneidbereich des Messers bzw. der Messerkörper der Schneidwalze ausgelenkt werden, um vorhandene Toleranzen zwischen dem Schneidbereich der Schneidwalze und dem Messer der Saugwalze zu kompensieren. Im Rahmen der Erfindung wird die Schneidwalze auch als Messerwalze bezeichnet.It is preferably provided that the cutting area of the knife or the knife body of the cutting roller are deflected to compensate existing tolerances between the cutting area of the cutting roller and the blade of the suction roller. In the context of the invention, the cutting roller is also referred to as a knife roller.
Beim Schneidvorgang des Materialstreifens wird hierbei durch die Annäherung des Schneidbereichs des Messerkörpers des Messers und der Schneidkante der Saugwalze ein Vollkant-Schnitt ausgeführt, wodurch die Schneidzeit bei einer Belageinrichtung verkürzt werden kann bzw. verkürzt ist. Durch den berührenden Kontakt zwischen den Schneidführungsflanken des Messerkörpers des Messers mit der Schneidkante der Saugwalze (Gegenwalze) wird der Messerkörper vor dem Schnittbeginn, vorzugsweise federnd, ausgelenkt, wobei unter Rotation der Schneidwalze und der Saugwalze der Schneidbereich des Messer bzw. des Messerkörpers und die Schneidkante der Saugwalze einander angenähert werden. Aufgrund des gleitenden Kontakts zwischen den Schneidführungsflanken des Messerkörpers und der Schneidkante der Saugwalze werden eventuell mögliche Schiefstellungen des Messerkörpers bzw. des Schneidbereichs zur Drehachse der Schneidwalze sowie mögliche Ungenauigkeiten im Winkel von der Schneidkante des Schneidbereichs zur Schneidkante der Saugwalze kompensiert.During the cutting process of the material strip, a full-edge cut is performed here by the approach of the cutting region of the knife body of the knife and the cutting edge of the suction roll, whereby the cutting time can be shortened or shortened in the case of a covering device. Due to the contacting contact between the cutting guide flanks of the knife body of the knife with the cutting edge of the suction roll (counter roll), the knife body is deflected before the start of cut, preferably resilient, with rotation of the cutting roll and the suction roll the cutting area of the knife or the knife body and the cutting edge of the suction roll are approximated to each other. Due to the sliding contact between the cutting guide flanks of the knife body and the cutting edge of the suction roll possibly possible misalignments of the knife body or the cutting area are compensated to the axis of rotation of the cutting roller and possible inaccuracies in the angle from the cutting edge of the cutting area to the cutting edge of the suction roll.
