PATENTAMT.PATENT OFFICE.

Von den bekannten zweiwalzigen Glatt-.From the well-known two-roller smooth.

kalandern, bei denen das Werkstück zwischen parallel gelagerten Walzen mit verschiedener Geschwindigkeit hindurchgeführt wird, unterscheidet sich der neue Glättkalander durch .die Art der Lagerung der Walzen zueinander.calenders, in which the workpiece is sandwiched between parallel rollers with different Speed is passed through, the new smoothing calender differs through .the type of storage of the rollers in relation to one another.

Statt der bisher angewendeten ParallellageInstead of the previously used parallel position

der Walzenachsen nach Fig. ι wird eine Schieflagerung der Walzen α und b zuein-the roller axes according to Fig. ι a misalignment of the rollers α and b is zuein-

jo ander eingeführt, wie in Fig. 2 und 3 in etwas übertriebenem Maßstabe veranschaulicht. Die Achsen der Walzen überschneiden sich danach' innerhalb der Walzenlänge selbst,jo others introduced, as in Fig. 2 and 3 in something exaggerated scale illustrated. The axes of the rollers then overlap ' within the roller length itself,

Ein solches Walzensystem mit zueinander winklig stehenden Walzen, von denen nur eine angetrieben . wird, bietet gegenüber den bekannten Friktionskalandern den Vorteil, daß man damit leicht die jeweils gewünschte Reibung erzeugt.Such a roller system with each other angled rollers, only one of which is driven. is offering towards the known friction calenders have the advantage that they can easily achieve the desired friction generated.

ao Walzen, deren Achsen parallel liegen, rollen ohne Ausübung seitlichen Druckes, übereinander weg. Sobald aber eine geringe Schiefstellung der Achsen herbeigeführt wird, so daß ein Überschneiden vorhanden ist, treten Druckwirkungen ein, durch welche die Walzen in der Achsenrichtung umso stärker verschoben werden, je mehr der Achswinkel wächst. Dies bietet die Ursache für "die stärkere Reibung, welche das zu behandelnde Material zwischen schief aneinander liegenden Walzen erleidet, und wodurch es an Glanz und Glätte gewinnt.. ...ao rollers, whose axes are parallel, roll away on top of each other without exerting lateral pressure. But as soon as a slight misalignment of the axes is brought about, so that there is an overlap, pressure effects occur, through which the rollers are displaced in the axial direction, the more the greater the axial angle increases. This provides the cause of "the greater friction, which suffers the material to be treated between obliquely adjacent rollers, and thereby gaining gloss and smoothness.. ...

Zumeist wird man bei dieser neuen Art und Weise der Hervorbringung glänzendster Preßeffekte mit Walzen verschiedener Form arbeiten, doch steht der Verwendung von Walzen mit gleichartiger Oberfläche nichts entgegen. Die Oberfläche einer oder mehrerer oder auch aller Walzen kann entweder, rauh oder glatt oder hoch poliert oder auch in irgend einer Weise unterbrochen sein. Die gewünschte Leistung ist dafür maßgebend.Most of the time one becomes the most brilliant with this new way of producing Press effects work with rollers of various shapes, but the use of Nothing against rollers with a similar surface. The surface of one or more or all of the rollers can either be rough or smooth or highly polished or even interrupted in some way. The desired performance is decisive for this.

Die erzeugte Reibung ist in weitesten Grenzen regelbar. Die Friktion, also der Wirkungsgrad der Einrichtung, wächst mit dem Winkel, den die Achsen einschließen, so daß durch dessen Veränderung der Grad des zu erzeugenden Glanzes bestimmt und die Schiefstellung der Walzen danach festgelegt werden kann. -The friction generated can be regulated within the broadest limits. The friction, so the The efficiency of the device increases with the angle enclosed by the axes that determined by changing the degree of gloss to be produced and the Inclination of the rollers can then be determined. -

Der neue Kalander soll zur Glättung von Papier, Karton, Pappen, Kunstleder, Leder, Holz, namentlich in Fourriieren, Geweben aller Art, Zelluloidplatten und dergl. dienen.The new calender is intended to smooth paper, cardboard, cardboard, artificial leather, leather, Wood, especially in fourriages, fabrics of all kinds, celluloid plates and the like. Serve.
