Description
Es ist bekannt, Papier oder andere Folien mittels eines umlaufenden, endlosen Bandes aus Kautschuk oder einem anderen dehnbaren Material zu kreppen, indem das Band während seines Umlaufs in der Querrichtung gedehnt und dann wieder zusammengezogen wird. Die Folie wird dem Band an einer gedehnten Stelle zugeführt, von ihm mitgenommen und bei der Zusammenziehung des Bandes gekreppt, worauf sie vom Band abgeführt wird.It is known that paper or other foils by means of a rotating, to crepe an endless band of rubber or some other stretchable material, by stretching the belt in the transverse direction during its revolution and then again is contracted. The film is fed to the belt at a stretched point, taken by him and creped when the tape was drawn together, whereupon she is discharged from the belt.
Die vorliegende Erfindung betrifft eine Vorrichtung dieser Art, welche dadurch gekennzeichnet ist, daß das Band über die Mantelfläche zwvcier kreisrunder, gleich großer Scheiben geführt ist, mit denen die Ränder des Bandes in Eingriff stehen, wobei die Wellen der Scheiben in einer Ebene liegen und mit einer durch die Mitten der Scheiben gehenden Achse gleich große Winkel bilden. Das Band kann entweder nur über diese zwei Scllciben oder über dieselben und gleichzeitig übe. eine zylindrische Walze geleitet werden. In beiden Fällen können zwischen den beiden Scheiben Stützen für das Band angeordnet sein.The present invention relates to a device of this type, which is characterized in that the band has two circular, the same size disks is performed, with which the edges of the tape in engagement stand, with the waves of the disks in one plane and with one through the centers of the disks going axis form equal angles. The tape can either only over these two discs or over the same and at the same time. a cylindrical roller. In either case, you can choose between the two Disc supports for the belt can be arranged.
Die Zeichnung zeigt schematisch einige. Ausführungsbeispiele der Vorrichtung gemäß der Erfindung.The drawing shows schematically some. Embodiments of the device according to the invention.
Fig. 1 zeigt eine Ausführungsform in axialem Durchschnitt; Fig. 2 zeigt dieselbe von der Seite; Fig.3 zeigt eine etwas abweichende Form in axialem Durchschnitt; Fig. 4 zeigt eine Ausführungsform mit einem Kautschukband, das zwischen den Scheiben gemäß Fig. 3 und einer zylindrischen Walze gestre-kt worden ist, von der Seite gesehen; Fig. 5 zeigt dieselbe Ausführungsform von oben gesehen.Fig. 1 shows an embodiment in axial section; Fig. 2 shows the same from the side; 3 shows a slightly different shape in the axial direction Average; Fig. 4 shows an embodiment with a rubber band between the disks according to FIG. 3 and a cylindrical roller has been stretched from seen the side; Fig. 5 shows the same embodiment seen from above.
Beim Ausführungsbeispiel nach Fig. i und 2 sind zwei Scheiben t mit
einer sphärischen Zone an den Enden einer Stange 2 angeordnet. Jede Scheibe i ist
auf ihrer Welle 3 befestigt. Die Wellen 3 liegen in derselben Ebene wie die Stange
2 tuid bilden mit ihr gleich große Winkel. Somit schneiden sich die Verlängerungen
der Wellen 3. Ein endloses Kautschukband ¢ ist um die Scheiben i herumgelegt und
greift mit seinen verdickten Rändern in ringförmige Nuten 5 am Umfang der Scheiben
i ein. Während der Umdrehung der Scheiben wird das Kautschukband von diesen mitgenommen.
Durch die Schrägstellung der Scheiben i zueinander wird das Band während seines
Umlaufs. in seiner Breite abwech-
