KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von gekrepptem Papier, insbesondere für Verpackungszwecke, Papiersäcke u. dgl., auf der Papiermaschine, und besteht darin, daß die Papierbahn, nachdem sie ■ in bekannter Weise vor dem Trocknen gekreppt oder gaufriert worden ist, während des Trocknens zwischen endlosen mitlaufenden Tüchern (Filztüchern oder Siebtüchern) oderThe invention relates to a method for producing creped paper, in particular for packaging purposes, paper sacks and the like, on the paper machine, and consists in that the paper web after it ■ creped in a known manner before drying or has been embossed while drying between endless cloths (felt cloths or sieve cloths) or
ίο zwischen Trockenzylindern und mitlaufenden Siebtüchern gehalten und geführt sowie in und mit diesen Tüchern einer kräftigen Pressung durch Druckwalzen ausgesetzt wird. Hierdurch werden die Kreppfalten oder Gaufrierungen ohne Längung der Papierbahn in sich zusammengedrückt. Zugleich findet unter dem Druck der Walzen^ eine Nachverfilzung des noch feuchten Papiers statt. Bei Verwendung von mitlaufenden Siebtüchern wird außerdem eine feinere XTachgaufrierung der Kreppapierbahn erzielt.ίο is held and guided between the drying cylinders and the traveling cloths and is subjected to strong pressure by pressure rollers in and with these cloths. This compresses the crepe folds or embossments without elongating the paper web. At the same time, under the pressure of the rollers, post-felting of the still moist paper takes place. When using idler Siebtüchern also is a finer X T achgaufrierung the Kreppapierbahn achieved.
Durch dieses Verfahren wird infolge der Pressung die Oberfläche des Papiers glatter als bei gewöhnlichem Kreppapier, ohne daßThis process makes the surface of the paper smoother as a result of the pressing than with ordinary crepe paper, without

die Falten verloren gehen, ferner wird durch die Nachverfilzung die Festigkeit erhöht und die Ausziehbarkeit der Falten verringert. Endlich wird die lederartige Geschmeidigkeit des Papiers erhöht.the wrinkles are lost, and furthermore the firmness is increased by the post-felting the extensibility of the folds is reduced. The leather-like suppleness of the Paper increased.
