 das Rad j in die Kette   1n eingreift.   Hierauf wird diese in der Pfeilrichtung r bewegt, wodurch der andere. ebenfalls mit dem Steg i"fest verbundene Stab h den Halbkreis t beschreibt und so fort. 



   Nach Entfernung der Stäbe   A   wird die Gegenprofilplatte e auf das   Werkstück   niedergelassen. 



  Das Werkstück bleibt so lange auf der Platte b, bis es genügend trocken ist und beim Abnehmen von der Platte b seine Form beibehält, was schon nach wenigen Minuten der Fall ist. Die Verwendung einer
Gegenprofilplatte ist nicht unbedingt erforderlich. Das   Werkstück   kann auch auf andere Weise an die Platte b   angedrückt   werden, beispielsweise mittels der ebenen Platte d oder eines Gitters. Erfindungsgemäss können hiezu auch einzelne, gegebenenfalls gelenkig verbundene Stäbe u (Fig. 3) benutzt werden. 



   Die erfindungsgemäss hergestellten Wellpappe und Wellpapiere eignen sieh für jede Verwendungsart, insbesondere zur Versteifung von Verpackungsschachteln. 



   PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von Wellpappe (Wellpapier), dadurch gekennzeichnet, dass ganze Tafeln des Ausgangswerkstoffes in feuchtem Zustande zwischen Formplatten auf einmal gepresst und bis zum Erreichen der Formbeständigkeit erhitzt werden.

 the wheel j engages the chain 1n. This is then moved in the direction of the arrow r, whereby the other. also with the bar i "firmly connected bar h describes the semicircle t and so on.



   After removing the bars A, the counter profile plate e is lowered onto the workpiece.



  The workpiece remains on plate b until it is sufficiently dry and retains its shape when it is removed from plate b, which is the case after just a few minutes. Using a
Counter profile plate is not absolutely necessary. The workpiece can also be pressed against the plate b in other ways, for example by means of the flat plate d or a grid. According to the invention, individual, possibly articulated rods u (FIG. 3) can also be used for this purpose.



   The corrugated cardboard and corrugated paper produced according to the invention are suitable for any type of use, in particular for stiffening packaging boxes.



   PATENT CLAIMS:
1. A process for the production of corrugated cardboard (corrugated paper), characterized in that whole sheets of the starting material in the moist state are pressed between mold plates at once and heated until they are dimensionally stable.

Claims

2. The method according to claim 1, characterized in that the material is pressed into the grooves of the base (b) by means of rods coming into effect one after the other, the last rod used in each case being left in the groove at least until the next following groove a rod has been pushed in.

3. Device for performing the method according to claim 1, characterized in that the organ for holding the material nestled against the grooved base is formed by a series of rods, the connection of which is possibly an articulated one.

4. Device for carrying out the method according to claims 1 and 2, characterized in that two serving to nestle the material on the support plate, the shape of their grooves adapted rods (it) through connecting members (i ', i "), in which they can be rotatably held, are connected and are held at a distance of two grooves of the support.
