Die Antriebsriemscheibe α und das Rad b sind auf die Welle c aufgekeilt. Das Rad b greift in das Zahnrad d1 ein, welches mit der Oberwalze des Walzenpaares I fest auf einer Welle sitzt. Das Rad dl greift in das Rad dn ein, welches mit der Unterwalze des Walzenpaares II auf einer Welle sich befindet. Das Rad d11 greift in das Rad dm ein, welches auf einer Welle mit der Oberwalze des Walzenpaares III befestigt ist etc.The drive pulley α and the wheel b are keyed onto the shaft c. The wheel b engages in the gear wheel d 1 , which sits firmly on a shaft with the top roller of the roller pair I. The wheel d l engages in the wheel d n , which is on a shaft with the lower roller of the roller pair II. The wheel d 11 engages in the wheel d m , which is attached to a shaft with the top roller of the roller pair III, etc.
Die treibenden Walzen haben alle gleichen Durchmesser, folglich auch die Zahnräder d^dn und dm etc., so dafs die Umfangsgeschwindigkeit sämmtlicher Walzen gleich grofs ist.The driving rollers all have the same diameter, consequently also the gears d ^ d n and d m etc., so that the peripheral speed of all the rollers is the same.
Das Wellen der Bleche geht folgendermafsen von statten: Die gerade Blechplatte wird von dem Walzenpaar I auf den nach den Walzen spitz zulaufenden Tisch e gelegt, nach beiden Seiten niedergebogen und in die Walzen hineingeschoben. Diese ziehen das Blech durch und bilden die erste Welle (s. Fig. 3); beim ■ weiteren Vordringen streifen die beiden niedergebogenen Theile über die Zungen f1, welche sich zwischen den Walzenpaaren I und II befinden.The corrugation of the sheets takes place as follows: The straight sheet metal plate is placed by the pair of rollers I on the table e which tapers to a point after the rollers, bent down on both sides and pushed into the rollers. These pull the sheet through and form the first wave (see Fig. 3); As the advance further, the two bent-down parts brush over the tongues f 1 , which are located between the pairs of rollers I and II.
Die Lage der Zungen fl ist so angeordnet, dafs die Blechtheile sich nach oben biegen, um von dem Walzenpaar II >erfafst werden zu können, welches, wie aus Fig. 4 ersichtlich, an jeder Seite eine halbe Welle anbiegt.The position of the tongues f l is arranged in such a way that the sheet metal parts bend upwards in order to be able to be grasped by the roller pair II> which, as can be seen in FIG. 4, bends half a shaft on each side.
Der Theil des Bleches, welcher das Walzenpaar II passirt hat, wird wiederum an den Seiten durch die Zungen fu niedergebogen, um von dem Walzenpaar III aufgenommen werden zu können (s. Fig. 5). Im Walzenpaar III wird ebenfalls an jeder Seite eine halbe Welle angebogen. Nun wird das Blech durch die Zungen fm aufgebogen, um das Walzenpaar IV passiren zu können etc., bis das Blech in seiner ganzen Breite gewellt ist.The part of the sheet which has passed the pair of rollers II is again bent down on the sides by the tongues f u , so that it can be picked up by the pair of rollers III (see Fig. 5). In roller pair III, half a shaft is also bent on each side. Now the sheet is bent open by the tongues f m in order to be able to pass the pair of rollers IV, etc., until the sheet is corrugated in its entire width.
