PATENTSCHRIFTPATENT LETTERING

KLASSE 55: Papierherstellung.CLASS 55: Paper manufacture.

Patentirt im Deutschen Reiche vom 29. Juni 1898 ab.Patented in the German Empire on June 29, 1898.

Um ein starkes Kleben des Stoffes an der oberen Prefswalze der Nafspressen zu verhindern und zu ermöglichen, mit stärkerem Druck der Pressen zu arbeiten, somit besser zu entwässern und Stoffe zu verarbeiten, die sonst wegen der starken Adhäsion an den Pressen zum Durchgang durch die Nafspressen nicht geeignet sein würden, werden die oberen Prefswalzen gemäfs dem Patent Nr. 99215 aus krystallinischer Steinart (Granit, Porphyr, Syenit u. s. w.) hergestellt oder aus Steinarten, die aus Theilen von verschiedener Härte zusammengesetzt sind, z. B. Sandstein.To prevent the fabric from sticking to the top roller of the press and make it possible to work with stronger presses, thus better dewater and process materials that would otherwise be due to the strong adhesion to the presses would not be suitable for passage through the presses, the upper pref rollers become according to Patent No. 99215 Crystalline stone type (granite, porphyry, syenite, etc.) or from stone types made of Parts of different hardness are composed, e.g. B. sandstone.

Die Vortheile der Verwendung dieser Steinarten für die oberen Prefswalzen der Nafspressen sind:The advantages of using these types of stone for the upper prefabricated rollers of the presses are:

Geringe Adhäsion des Stoffes an diese Walzen gegenüber den bisher angeordneten Walzen und infolge dessen die Möglichkeit, mit stärkerem Druck der Pressen zu arbeiten, den Stoff somit besser zu entwässern und Stoffe zu verarbeiten, welche sonst infolge ihrer starken Adhäsion an den oberen Prefswalzen nicht zum Durchgang durch die Nafspressen geeignet sein würden.Low adhesion of the fabric to these rollers compared to those previously arranged Rollers and, as a result, the possibility of working with higher pressures, to dewater the material better and to process substances, which otherwise as a result Their strong adhesion to the upper prefrollers does not allow passage through the presses would be suitable.

Aufserdem findet kein Durchbiegen der Prefswalzen bei starkem Druck statt, da die Steinarten nicht elastisch sind.In addition, there is no sagging of the pref rollers when there is strong pressure, since the Stone types are not elastic.
