Vorliegende Erfindung betrifft eine Verbesserung bei der Eincylinder-Papiermaschine, die gewöhnlich Papier herstellt, welches halbglatt, d. h. glasirt auf der einen Seite und auf der anderen Seite maschinenglatt ist. Die Verbesserung besteht darin, dafs man auf einer kurzen Strecke vermittelst einer Rolle das Papier vom Trockencylinder wegführt. Dadurch erhält man ein Papier, welches auf den beiden Seiten maschinenglatt ist.The present invention relates to an improvement in the single cylinder paper machine, which usually makes paper that is semi-smooth, d. H. glazed on one side and on the other side is machine-smooth. The improvement consists in being on one A roller guides the paper away from the drying cylinder over a short distance. Through this the result is a paper that is machine-smooth on both sides.
Die hierzu nöthige Einrichtung ist auf beiliegender Zeichnung schematisch veranschaulicht. The equipment required for this is schematically illustrated in the accompanying drawing.
Bei den gewöhnlichen Eincylinder - Papiermaschinen wird die auf dem Oberfilz 0 hergeführte Papiermasse, nachdem sie die Prefsrollen PP passirt hat, auf den Trockencylinder T überführt, und das Papier M verläfst wieder den Cylinder bei dem Punkt s in vollständig fertigem Zustand als halbglattes Papier, indem die an dem Trockencylinder anliegende Seite des Papiers glasirt ist, wogegen die andere Seite maschinenglatt ist.In the ordinary Eincylinder - paper machines on said upper felt 0 hergeführte pulp, after it has passed the Prefsrollen PP, transferred to the Trockencylinder T, and the paper M verläfst again the cylinder at the point s in completely finished condition as a semi-glossy paper, by the side of the paper lying against the drying cylinder is glazed, while the other side is machine-smooth.
Um diese Glasirung der einen Seite des Papiers zu vermeiden und um das Papier gleich glatt auf beiden Seiten zu erhalten, wird in der Nähe der Prefsrollen PP eine Rolle V angebracht, so dafs das Papier auf einer kurzen Strecke a-b vom Trockencylinder weg und. aufsen um diese Rolle herumgeführt wird.In order to avoid this glazing of one side of the paper and to keep the paper equally smooth on both sides, a roller V is attached near the pressure rollers PP so that the paper is a short distance away from the drying cylinder and. outside around this role.
Der Erfolg der Erfindung — die Vermeidung der inneren Glasirung der Oberflache des Papiers ■—■ basirt auf praktischen Versuchen und mufs dem Umstand, dafs das Papier auf einer kurzen Strecke vom Trockencylinder weggeführt wird, also eine Abkühlung, nachdem es erst zum Theil getrocknet worden ist, erleidet, zugeschrieben werden.The success of the invention - the avoidance of the internal glazing of the surface of the paper is based on practical experiments and must depend on the fact that this Paper is led away from the drying cylinder over a short distance, i.e. cooling, after it has only been partially dried, it may be ascribed.
Die in diesem Fall benutzte Rolle V kann durch jeden anderen für die Absicht zweckmäfsigen Constructionstheil ersetzt werden. The role V used in this case can be replaced by any other constructional part that is expedient for the purpose.
